Treatment process of industrial tail gas

Abstract

The invention belongs to the field of chemical separation and environmental protection, and particularly relates to a treatment process of industrial tail gas. The process comprises the following steps: feeding odorless air into the industrial tail gas to reduce the concentration of malodorous substances, so as to reduce bad odor; carrying out condensing and cooling on the industrial tail gas to separate out harmful substances from the industrial tail gas; introducing the industrial tail gas into a treatment system to treat dust, volatile organic compounds and the like in the industrial tail gas; and collecting the treated industrial tail gas. A treatment system in the process comprises a dust removal chamber, a transmission belt, a dust cleaning pond, a washing tank, a connecting pipe andan activated carbon adsorption tank, and further comprises a dust removal module, a sand filtration module, a stirring module and a washing module. During a use process, the industrial tail gas sequentially passes through the dust removal module, the sand filtration module, the stirring module and the washing module, and then reaches the activated carbon adsorption tank through the connecting pipe. A drying layer in the connecting pipe and activated carbon in the activated carbon adsorption tank are used for treating and absorbing moisture and organic matter in the industrial tail gas.

Description

technical field [0001] The invention belongs to the field of chemical separation and environmental protection, in particular to an industrial tail gas treatment process. Background technique [0002] The sustainable development of the chemical industry and even the entire human society puts forward higher requirements for energy saving and emission reduction. In this regard, industrial tail gas, as the main source of gas pollution, is a key point worthy of attention. Activated carbon adsorption is currently the most widely used industrial tail gas treatment method. This method has fast adsorption speed and relatively thorough purification of gas, which is very suitable for application in daily life. However, activated carbon has a small adsorption capacity and is easily poisoned and deactivated. It is incompetent in the treatment of industrial exhaust gas with a huge discharge volume, and it is often reduced to a decoration. In contrast, solvents have a large capacity for...

Problems solved by technology

However, the traditional absorption method is difficult to reach the theoretical level of more than ten, and in order to achieve effective mixing and mass transfer, generally do not use high-viscosity absorbents, which limits the improvement of recovery rate and the selection range of absorbents
