The cleaning of industrial filter cloth has always been a problem in everyone's mind. Industrial filter cloth synthetic fibers are mainly polypropylene, polyester, polyamide, Vinylon, etc., of which polyester and polypropylene are the most commonly used, based on solid-liquid separation, while polyamide is widely used in coal washing plants because of its excellent wear resistance. Polyester, polypropylene, nylon, Vinylon, cotton and other materials of filter cloth, screen, are widely used in pharmaceutical, chemical, dye, iron and steel, construction, iron metallurgy, chemical industry, ceramics, cement, geology, minerals and other industries.

Filter filter cloth washing is not clean how to do?

The quality and cleanliness of the filter cloth will directly affect the filtration effect of the filter, if the filter cloth of the belt filter is not clean, it will directly affect the water permeability of the filter cloth, which will lead to the problem of sludge dehydration, the amount of desilting is reduced, and the water content of the mud cake is high. So, what factors cause the filter cloth cleaning is not clean?

1, the pressure of the washing water is too low: the pressure of the washing water will affect the cleaning effect of the filter cloth, which is easy to understand, the washing water pressure is large, the washing strength will be large, and the washing pressure is small, if the pressure is too small, it is difficult to wash off the sludge on the filter cloth. The situation that the flushing water pressure is too low is generally caused by the leakage of the flushing pipe, the failure of the flushing pump, the blockage of the backwashing filter net garbage, or the blockage of the nozzle of the washing filter cloth.

Solution: Check whether the flushing water pipe leaks; Whether the flushing pump is faulty, observe the pressure strength change of the flushing water at any time, and be sure to clean up in time once the filter is blocked.

2, the amount or proportion of flocculant is improper: the flocculation of sludge and flocculant will have a certain impact on the dehydration effect, if the proportion concentration or dosage of flocculant is too high, it will not only waste the agent, but also paste the filter cloth resulting in continuous reduction of water permeability, on the contrary, it will also affect the dehydration of sludge.

Solution: According to the characteristics of the sludge and the water content of the concentrated sludge, the ratio and dosage of the reagent should be adjusted appropriately; Extend the stirring time of the flocculant, so that the solvent can be fully dissolved, and avoid the residue of the flocculent clogging the filter cloth pores of the belt filter.

In fact, there are two main reasons why the filter filter cloth is not clean: 1. The pressure of the washing water is too low; 2. The dosage or ratio of flocculant is not appropriate, find the specific reasons and solve the filter cloth can be cleaned.
