Description

Catalyst water conservancy diversion tray

Technical Field

The application relates to a catalyst diversion tray which is mainly suitable for containing a catalyst during flue gas treatment.

Background

The catalyst is commonly used for flue gas treatment in the environmental protection industry and has the shapes of flat plates, honeycombs, corrugations and the like. The bottom all need set up the support tray. The catalyst is generally arranged at the upper part of the catalytic tower, the inner wall of the tower body is annularly provided with supporting points, a bottom beam net is made of profile steel, a grid-shaped flat plate is paved on the bottom beam net, and a catalyst module is placed on the flat plate.

Catalyst modules are currently arranged in the manner described above. In order to improve the catalytic efficiency of the catalyst, the flue gas flow must be uniformly contacted with the catalyst from the uniform distribution angle as far as possible, except for the lifting from the catalyst module, a layer of gas flow uniform cloth layer is usually arranged at the bottom of the catalyst, the supporting points are annularly arranged on the inner wall of the tower body in the same way, the bottom beam net is made by profile steel, and the gas flow uniform distribution plates are installed. This has just caused tower body weight to increase direct cost to rise, and the equipartition layer girder generally adopts carbon steel and glass steel or glass scale anticorrosive, very easily corrodes after a long time and warp the dropping, has the potential safety hazard. Under the working conditions of dust contained in the flue gas and the like, the dust is very easy to deposit and scale, and the air flow circulation is influenced.
