FGD Vacuum Belt Dehydrator
FGD vacuum belt dehydrator is also called fixed vacuum chamber rubber belt filter; it is a new-type, high-efficiency, and continuous-operation solid-liquid separation mechanical equipment developed by our company on the basis of introducing, digesting, and absorbing technologies of similar foreign products. At the same time, it is also a kind of mechanical equipment that fully utilizes the gravity and vacuum suction to achieve solid-liquid separation. In the structure, the vacuum zone is arranged in the horizontal direction, and the length of the vacuum zone can be continuously used to complete different processes such as filtration, washing, and blotting etc. It has the advantages of high filtration effect, large production capacity, good washing effect, wide application range, simple and smooth operation and convenient maintenance etc. It is particularly suitable for filtering suspension slurry with solid coarse particles, high density and filter cakes need to wash many times. It can be widely used in solid-liquid separation in metallurgy, mining, chemical, papermaking, food, pharmaceutical and environmental protection and other industrial sectors; and it particularly has a good application in the wet flue gas desulfurization gypsum dehydration (FGD).
Rubber Belt Skirt and Baffle

The annular rubber belt of EP200 four-layer polyester cloth is used. The rubber belt skirt is made of a composite structure in which the corrugated skirt is bonded with the parallel rubber belt. The skirt in this structure has good flexibility and this structure can prevent the skirt from breaking when it changes direction in passing through the roller and can prevent the liquid from flowing out from both sides.

Rubber Belt Supporting Device

The rubber belt is supported by mandrel labyrinth sealed roller support, air cushion support and so on, which reduces the running resistance of the belt and prolongs the service life of the belt.

Drain Tank

It is found that the stainless steel used in the liquid collecting balance drain tank is not resistant to strong alkali and the nylon material used in the buoy should be replaced by the alkali corrosion resistant stainless steel or alloy material in time as needed.

Service Support

Whole Technological Design

Toncin determines reasonable plans and selections by conducting more systematic laboratory tests, semi-industrialization tests and theoretical analysis calculations and adopting appropriate methods in light of the actual problems faced by customers. And it determines specific parameters through laboratory tests and semi-industrial tests.

Product Advantages

- A ring friction belt is provided between the vacuum box and the filter tape and is sealed, lubricated and cooled by water. It provides reliable vacuum seal, which can maintain the stable reality, reduce the moisture content of the filter cake and is conducive to stable operating conditions. Moreover, the ring friction belt has small frictional resistance, long service life, and easy and quick replacement.

- The tape adopts air cushion support or water film cushion support or encrypted roller support. The tape floats on the support pad to reduce the operating resistance, which helps to prolong the service life of the tape.

- It adopts circular filter tape with high tensile strength and long service life.

- The overall structure has adopted a modular design that allows for flexible assembly and easy transport and installation.

- It has an airbag type filter cloth automatic correcting device that can ensure stable operation of the filter cloth.
