Industrial fume gas collecting assembly

Abstract

The invention discloses an industrial fume gas collecting assembly which comprises a gas collecting hood and an inner guide pipe. The gas collecting hood is fixed above a processing area of a workbench, and is connected with an air pipe; the inner guide pipe is connected from the inner part of the gas collecting hood, and is exposed outside the gas collecting hood; one end of the inner guide pipe communicates with the air pipe of the gas collecting hood; the other end of the inner guide pipe is used as a gas collecting port extending to a part near a dust producing point of the processing area of the workbench; and in addition, the gas collecting port of the inner guide pipe is arranged lower than a human body breathing area. According to the industrial fume gas collecting assembly provided by the invention, the gas collecting hood is arranged above a worker moving range so as not to affect worker operation; the inner guide pipe is connected to a position under the worker breathing area from the inner part of the gas collecting hood, so that most fumes produced during a technological operation process are collected by the inner guide pipe at the dust producing point; and the rest few uncollected fumes upwards escape into the gas collecting hood and are collected through admission ports in the gas collecting hood, so that not only can a large number of fumes or harmful gases produced during the technological process be prevented from harming a human body, but also an ideal dedusting effect can be achieved, and meanwhile, a worker operation space is not limited.

Description

technical field [0001] The invention belongs to the technical field of flue gas collection, and in particular relates to an industrial smoke dust gas collection component. Background technique [0002] The smoke and dust generated during some process operations are moved upward by the action of heat, such as the smoke and dust generated during the welding process, and the harmful gas evaporated during the heating process. [0003] For the collection of this type of smoke and dust, an upper gas collection hood (top suction hood) is usually set above the workstation, such as the Chinese patent application number 201410115683.5, or the Chinese patent application number 200720083841.9, which disclose all traditional structures The top suction hood, by setting the top suction hood on the top of the processing area, can effectively collect the smoke or exhaust gas that rises into the gas collection hood with the air flow, and the required air volume is small to achieve the ideal c...

Problems solved by technology

[0005] The technical problem solved by the present invention is to provide a new type of industrial smoke and dust gas collection assembly for the existing top suction hoods and side suction hoods that easily affect the breathing health of operators and low dust collection efficiency. On the basis of the capture efficiency, it can effectively improve the harm caused to human breathing during the process of flue gas capture
