Description

Practical vacuum filter cloth washs regenerating unit

Technical Field

The utility model belongs to the technical field of chemical equipment, and particularly relates to a practical filter cloth cleaning and regenerating device of a vacuum filter.

Background

Rubber vacuum belt filters are widely used as a common solid-liquid separation device in ash-water separation processes in coal gasification ash-water treatment. The belt filter takes filter cloth as medium, the slurry is uniformly distributed on the filter cloth, the filter cloth and materials are driven by a rubber large adhesive tape to run, and liquid passes through the filter cloth by utilizing the gravity and vacuum suction of the slurry, and solids are intercepted on the filter cloth, so that solid-liquid separation is realized. In the filtering process, fine solid particles can be attached to the surface of the filter cloth or partially enter the inside of the filter cloth to block the pore channels of the filter cloth so as to influence the filtering effect. The original filter cloth cleaning device uses the production water with the pressure of 0.4MPa as flushing water, can not effectively clean the filter cloth, and also increases the load of ash water treatment of a production system. When the filter cloth is seriously blocked, the high-pressure cleaning gun is required to be used for flushing, so that the working efficiency is seriously affected, the filter cloth is easy to damage, the service life of the filter cloth is shortened, the running maintenance cost of equipment is improved, and the influence on a production system is huge.
