The film-coated filter bag uses the film-coated surface to replace the traditional primary layer cake with uniform and fine pore sizes, making the dust penetration rate close to zero.
Unlike traditional filter bags, which accumulate and adhere to the filtered dust to form powder cakes and cause blockage, the PTFE microporous membrane has excellent performance. Its filtration method is membrane surface filtration, which can intercept 100% of the filtered matter.
The advantages are as follows.
(1) High surface filtration efficiency? Usually industrial filter materials are depth filtration, which relies on the establishment of a dust layer on the surface of the filter material to achieve effective filtration.
It takes a long time to establish effective filtration (about 10% of the entire filter layer), large resistance, low efficiency, incomplete interception, large loss, high filtration and backflush pressure, frequent cleaning, high energy consumption, and long service life Not long, the equipment occupies a large area.
When using a film-coated filter bag, dust cannot penetrate into the filter material. It is surface filtration. Whether it is coarse or fine dust, all is deposited on the surface of the filter material. That is, the pore size of the PTFE microporous membrane itself intercepts the filtered material, and the material is initially filtered. Period, effective filtering started at the beginning, and was in effective filtering for the last **** time.
(2) Low-pressure, high-flux continuous operation? Once the traditional depth filtration filter material is put into use, dust penetrates, a dust layer is established, and the air permeability drops rapidly.
During filtration, the dust accumulated inside causes clogging, thereby increasing the resistance of the dust equipment.
The micropores and non-stickiness of the membrane-coated filter material make the dust penetration rate close to zero. It provides the highest filtration efficiency after being put into use. When the filtered matter deposited on the surface of the PTFE microporous membrane filter material reaches When it reaches a certain thickness, it will automatically fall off and be easy to clean, so that the filtration pressure is always kept at a very low level, the air flow is always kept at a high level, and it can work continuously.
(3) Easy to clean? The operating pressure loss of any filter material directly depends on the amount of dust that remains or stays on or under the surface of the filter material after cleaning. The cleaning time of the coated filter cloth only takes a few seconds. Yes, it has very superior dust cleaning characteristics. Every time it is cleaned, the dust layer can be completely removed. The inside of the filter material will not be clogged, the void ratio and mass density will not be changed, and low-pressure loss operation can be maintained at regular intervals.
(4) Long life? PTFE microporous membrane-coated filter material can exert its superior characteristics regardless of the life-span cleaning mechanism. It is a filter material designed to fully exert its high-efficiency filtration function in the dust collector. , so the cost is low.
The coated filter material is a strong and soft fiber structure, which is compounded with a strong base material, so it has sufficient mechanical strength, coupled with excellent dedusting properties, it reduces the dust cleaning intensity. With low and stable pressure loss, it can be used for a long time, extending the life of the filter bag.
