Decontamination device with self-priming double Venturi structure and its application

Abstract

The invention relates to a decontamination device with a self-priming double-venturi structure and its application, which mainly solves the problems in the prior art that the arrangement mode is single, cannot meet the emergency decontamination of toxic gas, and the decontamination efficiency is low. The present invention adopts a decontamination device with a self-priming double-venturi structure, including a gas straight pipe inlet, a liquid annular inlet, a Venturi tapering section, a Venturi expanding section, a built-in Venturi liquid inlet pipe and a built-in Venturi section Composition, in which the liquid annular inlet is located above the inlet of the gas straight pipe, and connected to the Venturi tapering section after passing through a straight pipe. The Venturi tapering section is divided into two areas: the inner area and the outer area: the inner area circulates gas, and the outer area circulates The top of the liquid is connected to the Venturi expansion section, the built-in Venturi liquid inlet pipe is connected to the built-in Venturi section, and the built-in Venturi section is located in the Venturi expansion section. The technical scheme of connecting with the expansion section solves the above problems well. in decontamination.

Description

technical field [0001] The invention relates to a decontamination device with a self-priming double-venturi structure and its application, and belongs to the field of emergency treatment equipment for hazardous chemical accidents, in particular to the field of disposal of toxic and harmful gases by absorption method. Background technique [0002] In hazardous chemical leakage accidents, there are usually hazardous vapors and leaked liquids at the same time, and the absorption method is often used to decontaminate them. Among many decontamination equipment, Venturi scrubber has the advantages of simple structure, high purification efficiency, and convenient operation, and is widely used in the fields of gas absorption and industrial dust removal. [0003] The Venturi scrubber is generally divided into a constriction section, a throat section and an expansion section, and the liquid enters the Venturi scrubber through injection or negative pressure suction generated by the thr...

Problems solved by technology

[0005] One of the technical problems to be solved by the present invention is that there is a single arrangement in the prior art, which cannot meet the emergency decontamination of toxic gases, and the problem of low washing efficiency. A new self-priming double-venturi structure decontamination device is provided. It has various arrangements, can meet the emergency decontamination of toxic gases, and has the advantages of high washing efficiency
