Vacuum belt filter

Vacuum belt filter is a kind of equipment which uses vacuum negative pressure as driving force to realize solid-liquid separation. In structure, the filtering section is arranged along the horizontal length direction, which can continuously complete filtration, washing, drying, cloth regeneration and other operations. The vacuum belt filter has the advantages of high filtration efficiency, large production capacity, good washing effect, low moisture content of filter cake, flexible operation and low maintenance cost. Vacuum belt filter can be widely used for solid-liquid separation in metallurgy, mining, chemical industry, paper making, food, pharmaceutical, environmental protection and other fields, especially in gypsum dehydration (FGD) in flue gas desulfurization.

working principle

Vacuum belt filter is to form negative pressure at the filtrate outlet as the driving force of filtration. The filter is divided into intermittent operation and continuous operation. The vacuum filter with intermittent operation can filter various concentrations of suspension, while the continuous operation vacuum filter is suitable for filtering thick suspension containing more solid particles.

Filter with intermittent operation has been developed due to its automatic operation, and its filtering area is becoming larger and larger. In order to obtain the filter residue with low moisture content, the mechanical press filter has been developed.

A simple filter is formed by dividing the container into upper and lower cavities with filter media. When the suspension is added into the upper chamber, it enters into the lower chamber through the filter medium under the pressure, and the solid particles are intercepted on the surface of the filter medium to form filter residue (or filter cake).

During the filtration process, the filter residue layer on the surface of the filter medium is gradually thickened, and the resistance of liquid passing through the filter residue layer increases, and the filtration speed decreases. When the filter chamber is full of filter residue or the filtration speed is too small, stop the filtration, remove the filter residue, and regenerate the filter medium to complete a filtration cycle.

The liquid must overcome the resistance when passing through the filter residue layer and the filter medium, so there must be a pressure difference on both sides of the filter medium, which is the driving force to realize the filtration. When the filtration pressure is large, it will slow down the filtration pressure.

There are three ways of suspension filtration: filter residue layer filtration, deep filtration and screen filtration. The filter residue layer filtration refers to the initial filter residue layer formed after the initial stage of filtration. After that, the filter residue layer plays a major role in the filtration, at which the large and small particles are intercepted; the deep filtration refers to the pore channel with thicker filter medium, less solid particles in the suspension and smaller particles than the filter medium. During filtration, the particles are absorbed in the channel after entering; Screen filtration is a filtration method in which the solid particles retained are larger than the pores of the filter medium, and the solid particles are not adsorbed in the filter medium, such as the rotary drum filter screen to filter the coarse impurities in the sewage.
