introduction
the melt filter is polyester production in the one of the most key equipment. Usually end together from the output of the melt the kettle melt pump after the boost to the melt filter, filter it particle cutting machine to cut grain. I company article 3 polyester thread all use PRINCO company produces the HYPOX filter, a few years to run a stable, reliable. When filtering room dirty, melt filter room cleaning is in place, cleaning scope includes filter room and filter elements, filter and turned to the room between the melt pipes, and turning to the valve channel. With biochemical unit (condenser and washing tower), so row into the atmosphere pollutants as cleaning process is the minimum, and fully automatic.
1 process and characteristics
process as shown in figure 1 below.
melt filter have 2 filter room, rotation, through the work of the sliding import/export to switch valve. When filtering room A work, that is A place filter room Health assessment in “working” work of the state, import/export to valve are in the room, A side of the melt filter by the entrance to the valve to filter room, after A filter from export to the output.
filter is used to heat the room as the hot air carrier. 2 A filter room were used to heat 2 set of independent heating system, to the filter room for A, B 01 will air fan to heater E 02 heating, and then sent to the filter room of A clip set, hot air makes A close system recycling. Heater E 02 use electric heating, into A hot air filter room temperature control by TIC281A.
to the filter room B speaking, it is by heater E air heating, the same into the hot filter room B air temperature control by TIC281B. Import/export to valve, melt pipelines are is the HTM clip set of heating.
when filtering room A dirty, the entrance of the melt pressure (PT242 detection) is by increased, usually when pressure rises to 8 MPa, is switching filter room, that is, from A switch to the work room B filter. Import/export to the valve can switch is automatic, can also manually remote control, in order to ensure that the process of switching particle cutting machines not discharge, use more manual Folk network this switch.
when filtering room A switch to filter room B, first is to to the filter room B preheating, when filtering room temperature rise after opens to the B need constant temperature 12 h, after 12 h, filter room B from state (Prehea ting preheated) into the state, this said today can be filtered room A to filter room B switching.
in complete filter room from A to B switching filter room after room “B” is working, filter, at this time will immediately to filter room in A residual melt on emissions. Open A side entrance to filter room in the discharge valve valve QD1.1, through the connection nitrogen pipe to filter room A blind flange plate at the top of the place, and let the nitrogen into the room, open A filter filter room A side inlet valve place to the discharge valve, such QD1.1 residue in A room in the melt filter is the QD1.1 flow to the interior of the car emissions, A few minutes later, manual valve and will open QD2.1 export to the side as the discharge line row, discharge shall not exceed 2 h time.
in emissions, A filter room during the hot air still maintain 285 ℃, that is TIC281A still press the original value in control operation.
emissions ended, filter room cleaning A will be A clean room, filter is in place, the HYPOX process, from the hydrolysis and 2-1 hydrolysis and 2-1 pyrolysis pyrolysis, oxidation is automatic. When filtering room over A oxidation is automatically into “standby” condition, waiting for filtering out after cooling room, clean wicks wicks replacement, and then A filtered room is as backup.

Since the cleaning filters out of simple fault
since cleaning filter machine as a new type of filter machine, automatic cleaning, because it has automatic decontamination, cleaning continuous flow, automation degree higher many merits, so in many fields has a wide range of applications, from cleaning in use process of filter machine might meet many problems and fault, these problems and fault often will influence the cleaning filter the normal operation of the machine, which affects the normal operation of the water system. Understand the basic structure of cleaning filters and common failure to guarantee the water out the normal operation of the system is very important dae0kut. Here is a simple analysis from cleaning filter machine prone to some problems and the corresponding solutions.
an, from cleaning filter machine appear slack
since cleaning the leaking problem filters general will appear in the filter machine drive shaft part (barrel, welding flanges part is leaking in the range), appear this kind of problem there are two basic reasons, one is the drive shaft sealing ring material or specification requirements, so change to meet the requirements of sealing ring will do. The second is, sealing ring too long time running appear wear away, cause transmission shaft and filters between ontology lax and appear slack, sealed in a situation like that replaced the sealing ring corresponding specification can be to solve problems.
2, from cleaning filter machine automatic drain valve failure
some users of the system from cleaning filter machine in using longer after period of time will appear to be automatic drain valve failure, the specific performance of the filter machine automatic cleaning drain valve do not move or when the drain valve can’t open have been closed, appear this kind of problem since cleaning machine manufacturer of filter is generally choose of domestic of electromagnetic valve as drain valve use, the electromagnetic valve for the pilot type, first by the electromagnet open hole, then rely on leading the push aside the diaphragm constitute the system pressure open valve. Due to pollution water contains many impurities, very easy to block pilot hole, cause electromagnetic valve do not move or turn on the closed after lax. Changsha spirit more environmental protection technology Co., LTD, the clean production since JiXuan filter with electric ball valve or Israel, the original import of hydraulic electromagnetic valve as drain valve is completely solved at the electromagnetic valve for the cleaning machines automatic drain valve easy to filter out the problem. Fault
three, automatic cleaning control system fault
some users in the use of the filter in the process of cleaning machine will find that the cleaning filter machine start cleaning water caused by frequent increases, filters, life shorten has this problem is by filtering machine control system malfunctions or parameters Settings cause. It is mainly differential pressure differential pressure and the controller cleaning cleaning time Settings. Filter machine cleaning system frequent restart by setting more general may differential pressure range or adjust control system of the cleaning time to solve it.

Condensed type filter development and design
1 introduction
compressed air as a kind of power energy are widely used in petrochemical, textile, biochemical, national defense, and other fields. But the compressed air contains impurities. These impurities from the atmosphere, compressor itself and pipeline. According to statistics, scientific atmosphere every stere containing about 140 million particles, and 80% of the particle size less than 2 mm, and such small particles of compressor filter is can not be removed in; Use have oil lubrication compressor working process itself of the waste and pollution, according to the finished product gas compressor working conditions and type of difference, pollutants in 5-usually 50 mg/m3 changes between. At present domestic widely adopted without oil lubrication compressor most also just half without oil lubrication type. Because the crankshaft and the piston rod joint still use plenty of the splash lubrication, working part oil steam still will go into the cylinder piston rod, and lead to a trace of oil gas exist. In addition, the gas from the compressor out with temperature will drop water pipe in long separation and product, form rusty spot, meet that solid particles, impurities. So the compressed air purifying will Gender Health is very necessary.
2 air compressor of the original air filter structure, principle of compressed air before the air filter the depot GYF-3/8, GYF-6/8 type the oil-water separator to air purifying, its structure schematic diagram as shown in figure 1 shows, its working principle is: the compressor and cooler out from this device of the compressed air intake pipe into the spiral, separated, the bigger particles and droplet are thrown to the drain valve, inner eduction, the head of the department of taper sealing come after the collision cover flow, change gas into the chaos of bends to the accumulation of ceramic ring (rasching ring). Gas in ceramic ring between continuous baffle, make oil, water continue to separation. Gas continue to up the thick filter components, precision filtration components, finally the exhaust pipe eduction. The role of the tubing row is rough and fine filter out of the oil, water and dust from such as. After this device process after the air, oil content (5 mg/m3, including dust grain diameter (5 um, such the dusty index can only meet general, at the request of biochemical, medical, scientific research on the compressed air have higher requirements of the industry and can’t meet.
3 condensed type filter design, this paper attempts to develop the new type of coherence type filter structure schematic diagram shown in figure 2. It’s the job of the principle is: from the compressor lubrication oil discharge of the cooler gas back after the device to cut, in cylinder, and in the cylinder and the cylinder body in circular indoor air flow, high speed rotating compulsory form suspended in the air particles and bulky oil, bulky by centrifugal separation, water are thrown to the inner self, in under the action of the cone tube wall along the lid and cylinder of the gap between sinking, and deposition in the bottom of the container, the automatic drain valve eduction. Air cylinder to the spin and tapered cover meet, change direction of flow, baffle into stainless steel flat screen. The screen is a kind of like MoTong of very fine flat shape stainless steel wire to braid and become net belt, nets is even ring structure, gas to liquid and gas separation, and part of the solid particles. As these particles and droplet generation grew up in the screen surface smooth, sinking and eduction. The gas up fine filter, continue to realize aerosol body grew up and gravity, condensed landing sedimentary filter the ministry of concave oil and water from the row tubing.
4 condensed type filter the performance analysis of the structure of the oil-water separator is the collection centrifugal separation, crude filter, fine filtration three process at an organic whole, can effectively remove the compressed air dust, moisture, the impurities such as oil mist, the purification gas more than 1 mg/m oil content, including dust particle size (more than 1 u m. To T5967 JB/97 “pneumatic components and with air quality grading” medium oil, the dust index is equal to or greater than the performance of the filter the industry provide pure air source.
this new type of the development of the filter out original old products, it has the following advantages:
first of all, in the centrifugal separation method, it has changed the previously the sort of welding structure, and spiral by cutting into the intake of now. Avoid the processing method from the limited spiral of surface is uneven, welding large distortion, and not easy processing, welding, etc. The new structure makes processing technology simplified, reduced cost, and obviously improve the separation effect.
second, with domestic more successful screen except the components of the ceramic foams to replace the accumulation filtering method. Short section of the ceramic tube desultorily, passes through, the accumulation of the DuoCi baffle, collision, able to separate out part of oil, water, dust, but due to high pressure gas flow, cause ceramic tube of mutual impact, there will be broken particles, and easy in secondary air pollution. And stainless steel flat screen, is not a problem with pollution, and it extremely easy to clean, separation and good effect, reduced the rear fine filtration components load, and extend the life of pure filter.
the third, and the use of the essence of filter through identification to replace the old products to the original felt winding filtering method. With the extension of time felt filter will be impurities, extremely easy jam adsorption saturated felt hole, and greatly reduce the filtering area, increase the pressure loss. More seriously, if not keep clear of impurities, they felt hole through the hole and finished product after impurities mixed, make the original gas design index can not be achieved. And the precision filter is used new high-tech product, it can and western developed countries compared the precision filter beauty. This filter is the filtering mechanism through direct, inertia collision, spread (brown) movement, condensing comprehensive effect. The filter material adopting micro fiber woven from non-woven fabrics and enhance the distribution of rules have filter arrangement, because of the filter material surface is smooth, impurities in its surface, extremely easy sink after collection from the device, and make product the quality of the gas is assured.
fourth, the original manual sewage into has manual, automatic sewage and some. Usually will drain valve closed, automatic manual work drain valve. If automatic drain valve failure or repair the close, and adopt manual sewage. That design is the reason for the current domestic production: automatic drain valve although more, but the quality is not good enough. Foreign automatic drain valve quality reliable, but its cost though high, from the economic into consideration, not imported valves. So, using manual, automatic and some sewage is reliable and the economy.
5 epilogue
above all, new type of condensing type filter design is successful, in line with the principle and the design specification filter. It has higher precision filtration, accurate and reliable, gas flow uniformity, no stranded, small volume, let the dust amount and filter easy change, small resistance, long life and low cost, work automation degree higher many advantages. But with all the higher requirement of compressed air, higher accuracy, the design of the air filter and the new task, we face new challenges.

filters filter tailings benefits of mineral separation tailings is the product of extraction, after. Tailings processing have become urgent problems. Metal and non-metallic ores are generally after crushing, grinding, after such means as leaching or flotation concentrate, the rest of the tailings extract part at present most used pump hit tailings dam precipitation, and this part of tailings, its size is usually 200 item below 80%, some even more fine.
coal separation is not the case, and has not broken ground coal coking coal, coal or more selected at the end of a flotation, coal power plant coal flotation, therefore, is not whether a flotation, the tail of the particle size distribution of coal are nothing like metallic ore so fine, general 200 mesh the following is below 50%. Therefore, filter machine processing tailings has the following advantages:
the first benefits, is to not sensitivity, and in theory of grain size of the minimum size can reach 1 um. Other separation equipment, such as belt type filter machine/disk vacuum filter machine/pressure filter machine/ceramic filter machine/drum filter machine/barrel type filter machine/vertical scraper unloading please Google centrifuge and so on all is hard to adapt to a very fine particle size of material, like metal tailing that frequently 320 purpose dehydration processing, these devices seem to not satisfactory! (the dh_hksjn)
the second advantage is filter machine, static intermittent equipment, energy consumption belongs to than the continuous production filtering equipment, it is said that lower ceramic vacuum filter machine energy consumption is low, I find some material, so, it’s total energy consumption (including auxiliary equipment) and filters, but application is not the same as a wider range.
third advantage is filtering, machine maintenance is simple, and the workers, not easy to learn as many complicated equipment like, bad must manufacturers action, and if you point the domestic, and imported can spend great!
fourth benefits, is filtering machine performance is of good vacuum dehydration, such as lead and zinc tailings water we can achieve below 12%, gold tailings can achieve below 14%, of course, this is no impact on the yield of cycle time, well, very soon.
the first WuGeHao place, filter machine long service life, less easyworn parts, and I have seen 30 years ago filter still use, and vacuum class or pressure class
