Problems solved by technology

[0004] At present, a small number of smelting and separation enterprises in the non-ferrous metal industry adopt the water sealing process of the extraction tank to prevent the organic waste gas in the extraction tank from overflowing into the environment, but because the water seal cannot prevent the organic components and hydrochloric acid on the extraction surface from overflowing the liquid surface, a large amount of overflow Acidic organic waste gas only gathers in the upper space of the extraction tank, and will also be discharged into the environment when the water seal is short of water or the tank is overhauled, and the pollution of the atmospheric environment by the acidic organic waste gas cannot be completely eliminated

Embodiment 1

[0020] like figure 1 A micro-negative pressure extraction tank in the non-ferrous metal industry is shown, comprising a gas collection fan 6, an extraction tank, a main pipe 3 and a branch pipe 4, the extraction tank includes a front extraction tank 2 and an end extraction tank 1, and the gas collection fan 6 Connected with the dry pipe 3, the dry pipe 3 communicates with the extraction tank through the branch pipe 4, the bottom of the dry pipe 3 is also provided with a condensate collection pipe 5 near the end of the gas collecting fan 6, and the condensed water collection pipe 5 is in addition One end is connected with the upper part of the side wall of the front extraction tank 2.

Embodiment 2

[0022] like figure 1 and 2 as shown figure 1 A micro-negative pressure extraction tank in the non-ferrous metal industry is shown, comprising a gas collection fan 6, an extraction tank, a main pipe 3 and a branch pipe 4, the extraction tank includes a front extraction tank 2 and an end extraction tank 1, and the gas collection fan 6 Connected with the dry pipe 3, the dry pipe 3 communicates with the extraction tank through the branch pipe 4, the bottom of the dry pipe 3 is also provided with a condensate collection pipe 5 near the end of the gas collecting fan 6, and the condensed water collection pipe 5 is in addition One end is connected to the upper part of the side wall of the front extraction tank 2; the connection between the branch pipe 4 and the main pipe 3 adopts a 90 ° elbow 8, and the purpose of the vertical connection between the 90 ° elbow 8 and the side of the main pipe 3 is to prevent the exhaust gas from being extracted. After condensing in the main pipe 3, t...

Embodiment 3

[0024] The difference between this embodiment and embodiment 2 is that: the connection between the branch pipe 4 and the main pipe 3 adopts a 45° elbow.

Abstract

The invention discloses a micro-negative pressure extraction tank of the nonferrous industry, comprising a branch pipe, a main pipe, a condensate collection pipe and a gas collection fan, wherein the branch pipe is vertically connected to the cover plate of the extraction tank and fixed by a support; the branch pipe is vertically connected with the plane of the main pipe; and the tail end of the main pipe is connected with the gas collection fan so as to supply the collected waste gas to a waste gas treating device. The micro-negative pressure extraction tank of the nonferrous industry solves the problem that unorganized emission of acidic waste gas extracted in the extraction workshop of the nonferrous industry causes pollution on the atmosphere.

Description

technical field [0001] The invention relates to the technical field of waste gas treatment, in particular to a micro negative pressure extraction tank in the nonferrous metal industry. Background technique [0002] In recent years, the continuous growth of the world's population and the rapid development of industry have made the problem of environmental pollution more and more serious. Air pollution is one of the most prominent environmental problems in my country at present. Industrial waste gas is an important source of air pollutants. A large number of industrial waste gas emissions If it enters the atmosphere, it will inevitably reduce the quality of the atmospheric environment, bring serious harm to human health, and cause huge losses to the national economy. The waste gas extracted from the non-ferrous metal industry contains a large amount of pollutants such as: organic solvents, kerosene, hydrochloric acid and some raw materials in the non-ferrous metal industry. If ...
