Catalytic reaction tank for sewage treatment

Abstract

The invention discloses a catalytic reaction tank for sewage treatment, which comprises a cylindrical housing and a cylindrical liner, wherein a thermal insulation layer is arranged between the housing and the liner; a discharge pipe is arranged at the top of a barrel; a feed pipe is arranged at the bottom of the barrel; a plurality of catalyst reaction buckets are movably mounted in the liner; each catalyst reaction bucket comprises an upper circular screen end face, a lower circular screen end face and a cylindrical bucket wall; the diameters of the bucket walls are matched with the inner diameter of the liner; an annular baffle plate is arranged on an internal wall of the catalytic reaction bucket; a plurality of baffle through holes vertically formed are uniformly distributed in the baffle plate. The catalytic reaction tank is improved; the catalyst reaction buckets independent of the liner of a tank body are added in the tank body; a catalyst is convenient to collect and replace after long-term reaction; due to a combined action of a diverter and the baffle plate, the intensive mixing of sewage and the catalyst is facilitated; the reaction efficiency of the whole device is improved.

Description

technical field [0001] The invention relates to the field of catalytic reaction treatment of sewage, in particular to a catalytic reaction tank for sewage treatment. Background technique [0002] Catalytic oxidation is one of the methods used for sewage treatment. It mainly uses catalysts to treat sewage at a certain temperature and pressure, and catalyzes the oxidation of harmful substances in sewage to convert them into harmless substances. In order to meet the requirements of these reactions, a special catalytic reaction tank is required for the reaction. [0003] For the reaction tank itself, after the catalyst is used for a long time, the surface of the catalyst is easy to accumulate impurities in the sewage. At this time, the catalyst needs to be cleaned and replaced, so the tank with a sealed structure is not suitable for this reaction, and when replacing the catalyst, How to conveniently collect and take out the catalyst in the tank is also one of the problems that ...

Problems solved by technology

[0003] For the reaction tank itself, after the catalyst is used for a long time, the surface of the catalyst is easy to accumulate impurities in the sewage. At this time, the catalyst needs to be cleaned and replaced, so the tank with a sealed structure is not suitable for this reaction, and when replacing the catalyst, How to conveniently collect and take out the catalyst in the tank is also one of the problems that plague the technicians; finally, the catalyst needs to be evenly distributed in the reaction tank, and the contact area between the catalyst and the sewage directly affects the overall reaction efficiency
