Novel tail gas recovery device

Abstract

The invention provides a novel tail gas recovery device, which comprises a vacuum pump, wherein the vacuum pump comprises a discharge end and at least two suction ends, the vacuum pump is connected with a spiral cooling system through a pipeline, the spiral cooling system comprises a spiral cooling pipe, the periphery of the spiral cooling pipe is fixedly connected with an inner pipe wall, the inner pipe wall is fixedly connected with an outer pipe wall, the outer pipe wall and the inner pipe wall form a cooling liquid circulation cavity, and the cooling liquid circulation cavity is fixedly provided with a liquid inlet and a liquid outlet. The device is provided with a plurality of suction ends, so that a plurality of devices can be subjected to vacuumized waste gas treatment at the same time; an inner diaphragm with the composite PTEE coating is arranged, the inner diaphragm can reduce noise, and the composite PTEE coating can resist most corrosive gas; the spiral cooling system adopts a spiral pipe, so that tail gas and pure gas can be separated; and the whole machine is high in waste gas treatment efficiency, energy-saving and environment-friendly.

Description

technical field [0001] The invention relates to the technical field of tail gas recovery devices, in particular to a novel tail gas recovery device. Background technique [0002] The gas pump, also known as the air compressor, is the main body of the gas source device. It is a device that converts the mechanical energy of the motor into gas pressure energy. [0003] When dealing with corrosive waste gas, bipolar pumps with gas as the medium are usually used. Generally, one gas pump is only connected to one device, and the vacuum pumping efficiency of this method is low; generally, the liquefaction point of corrosive waste gas is higher , usually circulate it in the cooling liquid for liquefaction treatment, so as to separate the exhaust gas and pure gas. Contents of the invention [0004] Aiming at the problems pointed out in the background technology, the present invention proposes a novel tail gas recovery device. [0005] Technical scheme of the present invention is r...
