Embodiment Construction

[0013] Below the present invention will be further described in conjunction with the embodiment in the accompanying drawing:

[0014] Such as Figure 1~2 As shown, the present invention mainly includes a delivery pipe body 1 and a collection cover body 2, the delivery pipe body 1 is cylindrical, and the lower end of the delivery pipe body 1 is connected to the collection cover body 2.

[0015] The collection cover body 2 is a cone-shaped cylindrical structure with a large diameter at one end and a small diameter at the other end. The smaller diameter end of the collection cover body 2 is connected to the delivery pipe body 1, and a slide button 4 is provided on the outside of the larger diameter end of the collection cover body 2. The collection cover body 2 can be fastened on the aeration hose through the sliding buckle 4 to form an effective seal.

[0016] The conveying pipe body 1 and the collecting cover body 2 are integrally formed.

[0017] The inner side of the convey...

Abstract

Belonging to the technical field of fluidized beds, the invention relates to a gas collecting hood, in particular to a fluidized bed gas collecting hood. The fluidized bed gas collecting hood comprises a conveyer pipe body and a collecting cover body, and the lower end of the conveyer pipe body is connected to the collecting cover body. The collecting cover body is a conical cylinder structure with one large diameter end and one small diameter end, the small diameter end of the collecting cover body is connected to the conveyer pipe body, and the large diameter end of the collecting cover body is externally provided with a slide fastener. The conveyer pipe body is internally provided with a pipe body check ring. The fluidized bed gas collecting hood provided by the invention has the characteristics of simple, compact and reasonable structure, and stable and reliable work, can effectively collect the gas conveyed from an aeration hose and send it into a corrugated pipe, improves the gas collection efficiency, and has good gas collection performance.

Description

technical field [0001] The invention relates to a gas collecting hood, in particular to a fluidized bed gas collecting hood, belonging to the technical field of fluidized beds. Background technique [0002] Biological fluidized bed means that in order to improve the treatment efficiency of biofilm method, sand (or anthracite, activated carbon, etc.) is used as filler and biofilm carrier, and the wastewater flows through the sand bed from bottom to top to make the carrier layer in a flowing state, so that the Time to increase the contact area between biofilm and wastewater and sufficient oxygen supply, and use the boiling state of filler to strengthen the structure of wastewater biological treatment process. The biological fluidized bed process has high efficiency, less land occupation, and low investment. It has been used in the United States, Japan and other countries for advanced treatment such as sewage nitrification, denitrification, secondary treatment of sewage, and ot...
