Centralized industrial waste gas treatment system

Abstract

The invention discloses a centralized industrial waste gas treatment system which comprises a deodorization unit, a waste gas absorption unit and an acid-mist purification unit, wherein the deodorization unit comprises a deodorization tower; deodorization packing is arranged on a first grid; the waste gas absorption unit comprises an absorption chamber; an adsorptive material is arranged on a partition plate of the absorption chamber; the acid-mist purification unit comprises a purification tower; the deodorization packing is arranged on a second grid; and waste gases in a waste gas inlet pipe sequentially pass through the deodorization tower, the absorption chamber and the purification tower and then enter a waste gas outlet pipe under the action of a centrifugal fan. According to the treatment system disclosed by the invention, odorous gases in the waste gases are removed by the deodorization unit, gases capable of being absorbed by the adsorptive material are absorbed by the waste gas absorption unit so as to remove organic gases, and finally, the acid gases are neutralized by using alkali liquor of the acid-mist purification unit. Therefore, the acid gases in the industrial waste gases can be purified, so that the discharged gases meet the standards.

Description

technical field [0001] The invention relates to the technical field of industrial waste gas treatment, in particular to a centralized industrial waste gas treatment system. Background technique [0002] Smog is common in cities. In many areas of China, fog and haze are used together as a disastrous weather phenomenon for early warning and forecasting, collectively referred to as "smog weather". Smog is the result of the interaction between specific climatic conditions and human activities. The economic and social activities of a high-density population will inevitably emit a large amount of fine particulate matter (PM 2.5). Once the emission exceeds the atmospheric circulation capacity and carrying capacity, the concentration of fine particulate matter will continue to accumulate. range of smog. [0003] For the formation of smog, unfavorable meteorological conditions are generally external factors, and the main internal factor is the large-scale discharge of pollutants; a...

Problems solved by technology

[0010] However, most of the devices using the above processing technologies are single devices, that is, each device operates independently, which makes the synergistic crossover between devices, and the processing efficiency and processing effect after direct connection are unstable.
