Embodiment 1

[0025] A decontamination device with a self-priming double Venturi structure, such as Figure 1-Figure 2 As shown, this patent discloses a self-priming double-venturi structure decontamination device for gas-liquid treatment, which consists of a gas straight pipe inlet 1, a liquid annular inlet 2, a Venturi tapering section 3, and a Venturi expansion section 4 , a built-in Venturi liquid inlet pipe 5 and a built-in Venturi section 6. Among them, the liquid annular inlet 2 is located above the gas straight pipe inlet 1, and is connected to the Venturi tapering section 3 after passing through a straight pipe. The Venturi tapering section 3 is divided into two areas: the inner area 3-1 and the outer area 3-2: The inner area 3-1 only circulates gas, the outer area 3-2 only circulates liquid, and its top is connected with the Venturi expansion section 4 . The built-in Venturi liquid inlet pipe 5 is connected with the built-in Venturi section 6, and the external pipe section must b...

Abstract

The invention relates to a self-priming double-venturi structure decontamination device and an application thereof, which mainly solve the problems of single arrangement mode, inability to meet the emergency decontamination of toxic gases and low washing efficiency existing in the prior art. The self-priming double-venturi structure decontamination device comprises a gas straight pipe inlet, a liquid annular inlet, a Venturi tapered section, a Venturi enlarged section, a built-in Venturi liquid inlet pipe and a built-in Venturi section, wherein the liquid annular inlet is located on that inletof the gas straight pipe, passes through a straight pipe and is connected to the Venturi tapered section, the Venturi tapered segment is divided into two regions: the inner region and the outer region: the inner region circulates gas and the outer region circulates liquid, the top end of which is connected with the Venturi expansion section, the inner Venturi liquid inlet pipe is connected with the inner Venturi section, the inner Venturi section is located in the Venturi expansion section, the technical scheme connected with the expansion section solves the above-mentioned problems and can be used for 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...
