Vacuum belt dewatering machine is an important equipment for the secondary dewatering of the gypsum. The quality of the filter cloth determines the effect of the dehydration of the filter. The service life of the filter cloth is determined by the type, performance, working condition and temperature of the filter To decide. But in the process of using the filter cloth often clogging phenomenon, which will seriously affect the filter cloth filter effect.
Some power plants are not twenty-four hours in the boot, may stop using, as in this case if there is no timely cleaning filter cloth, gypsum will appear in the filter cloth surface scaling, silted cloth surface Gap, in the future will be difficult to clean the use, so as to shorten the service life of the filter cloth, but also affect the filter effect. So the filter shut down, must first filter the surface of the residual gypsum clean. Keep the surface of the filter cloth clean. Under normal circumstances the filter cloth in the use of a period of time when the need to be replaced, because the filter cloth in the normal use of a period of time, there will be deformation, shrinkage occurs;
In addition there are impurities in the treatment of impurities in the filter cloth can not be washed off, although the filter cloth is not damaged but has seriously affected the filtration effect. From the cyclone out of the gypsum slurry in the acid insoluble content will exceed the clogged filter cloth, acid insoluble the main source of three: 1, limestone powder containing insoluble in the acid content of substances such as carbides, heavy metal ions, Aluminum dioxide, insoluble silicate, alumina, clay and other refractory materials 2, the use of water-insoluble acid impurities in the water exceeded, and some power plant process water is recycled, which directly caused the process of acid insoluble High content, and ultimately lead to acid mist in the slurry seriously exceeded, blocking the filter cloth. 3, flue dust in the process of excessive impurities, especially electric dust, with high impurities, it is recommended that the use of dust bag bag.
