Vacuum belt dewatering machine is the primary 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, function, working condition and temperature of the filter Never decided. But in the process of using the filter cloth often show the phenomenon of congestion, which will seriously affect the filter cloth filter effect.
Some power plants are not twenty-four hours are on the boot, may stop using, like this situation if the downtime is not timely cleaning filter cloth, gypsum will appear in the filter cloth scale scaling, silted cloth appearance Gap, in the future will be difficult to use the cleaning, so shorten the life of the filter cloth, but also affect the role of filtration. So when the filter shut down, must first filter the appearance of residual plaster cleaning clean. Stick to the appearance of the filter cloth cleaning. Usually under the conditions of the filter cloth in the use of a period of time after the demand is 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 filter material can not be washed in the filter cloth, although the filter cloth is not damaged but now has a serious impact on the filtration. From the cyclone out of the gypsum slurry acid insoluble content of the overrun will block the filter cloth, acid insoluble the main origin of three:
1, limestone powder containing insoluble in the acid content of the overrun, such as carbide, heavy metal ions, alumina, insoluble silicate, alumina, clay and other refractory materials
2, the use of technical water insoluble in acid ion impurities overruns, and some power plant technology is the use of water recycling, so the direct formation of water acid insoluble content of the product, and finally lead to acid slurry insoluble overshadowed, blocking filter cloth.
3, flue dust in the process of excessive impurities, especially electric dust, with high impurities, so the power plant to use bag dust.
The above is the "filter cloth block how to prevent" the introduction, I hope to help you.
