Abstract

The invention relates to a gas-collecting hood for an anoxic tank. The gas-collecting hood is formed by splicing a plurality of arch-shaped cover bodies; the arch-shaped cover bodies are divided into type A and type B, wherein the tops of the type A arch-shaped cover bodies are respectively provided with a gas collecting hole, and the tops of the type B arch-shaped cover bodies are sealed; a frame is formed at the bottom of each arch-shaped cover body in a way of extending to the peripheral ring; each frame comprises a bending part and a vertical part; the vertical parts are connected with the wall of the anoxic tank, and the bending parts are vertical to the wall of the anoxic tank; one of the arch-shaped parts at the two sides of each arch-shaped cover body is in a convex shape, and the other arch-shaped part is in a concave shape; the arch-shaped cover bodies are in concave-convex connection with one another. The gas-collecting hood is convenient to splice and better in sealing property.

Description

technical field [0001] The invention relates to the field of gas-collecting hoods for sewage treatment, in particular to a gas-collecting hood for anoxic pools. Background technique [0002] Aerobic and anoxic technologies are used in large-scale sewage treatment processes, and aerobic pools and anoxic pools will inevitably produce waste gas during the process of sewage treatment. In order to prevent the waste gas from polluting the air, many sewage treatment plants will choose to treat sewage The pool is equipped with an air collecting hood. [0003] At present, most of the gas collection hoods on the market are integrated, that is, the size of the gas collection hood is customized according to the size of the sewage treatment tank, and the gas collection port on the top of the gas collection hood cannot be added at will. In addition, some gas collection hoods are spliced ​​together. However, the way of splicing is mostly the way of connecting nuts and bolts, the sealing p...
