Overview of The Vacuum Filter

General Description
The vacuum filter is a device to separate solids from a liquid by negative vacuum pressure. In terms of its structure, the filter is designed horizontally along the length direction to continuously realize filtering, washing, drying and the regeneration of filter cloth.

A Popular Type
Rubber belt filter possesses advantages of the high efficiency of filtration, large capacity of production, excellent washing effect, low moisture in filter cakes, flexible operation and low cost of maintenance. It is widely applied to the solid-liquid separation in many fields, such as metallurgy, mining, chemical industry, paper-making, food, pharmacy, environmental protection, etc., especially in gypsum dehydration of flue gas desulfurization (FGD).

How the vacuum filter works
The vacuum filter mainly serves to form the power of the negative pressure at the outlet of the filtrate. The filter can also be divided into intermittent operation and continuous operation, among which the intermittently operated one can filter suspensions with various concentrations, while the continuously operated are more suitable for filtering thick suspensions with more solid particles contained.
Besides, there are three ways of suspension filtration: slag layer filtration, deep layer filtration and sieve filtration which usually exist simultaneously.
