Self-priming packing decontamination device

Abstract

The invention provides a self-suction type packing decontamination device. A waste liquid collecting bin is provided with an air inlet and a first liquid discharge port; the waste liquid collecting bin is connected to a straight pipe section of a venturi tube; a decontaminant bin is disposed at the upper part of the waste liquid collecting bin; the venturi tube is wrapped by the decontaminant bin;the decontaminant bin is provided with an atmospheric communication hole and a liquid circulation hole; the decontaminant bin is provided with a second liquid discharge port; an annular cowling is downwards formed at the throat outlet of the venturi tube; the tail end of an annular liquid inlet chamber is disposed in the decontaminant bin; a gas-liquid distributor is arranged at a diffusion pipesection of the venturi tube; the gas-liquid distributor is connected to a packing decontamination bin; the packing decontamination bin is provided with a gas-liquid circulation hole; a housing cover is provided with the gas-liquid distributor and the packing decontamination bin; a housing is connected with the decontaminant bin; a spiral deflector is disposed on the outer side of the side wall ofthe packing decontamination bin; and an exhaust port is formed in a side wall of the housing. The self-suction type packing decontamination device has beneficial effects of being high in absorption efficiency and sufficient in absorption of gas-liquid hazardous chemicals, and convenient in decontamination operation for operators, and realizing emergency treatment of the gas-liquid hazardous chemicals.

Description

technical field [0001] The invention relates to the technical field of emergency treatment equipment for hazardous chemical accidents, in particular to a self-priming packing decontamination device. 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 gas-liquid hazardous chemicals. To decontaminate gas-liquid hazardous chemicals in an emergency state requires the absorption device to have high absorption efficiency and easy operation, so as to efficiently and conveniently deal with the leakage of gas-liquid two-phase hazardous chemicals. The absorption method is used to decontaminate gas-liquid hazardous chemicals. The basic principle is to remove harmful components through the process of contact, mass transfer and reaction between absorbent and gas-liquid hazardous chemicals. [0003] The Chinese patent literature with the noti...
