Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment components, in particular to a multi-stage adsorption component of a waste gas recovery tower. Background Art

[0002] In the process of industrial production, the emission of waste gas is an important issue. In order to protect the environment and achieve sustainable development, the recovery and treatment of waste gas has become crucial. At present, when the waste gas is treated, the waste gas is usually introduced into the corresponding waste gas recovery tower outside for treatment. The waste gas recovery tower generally uses liquid medicine to spray from the nozzle to treat the waste gas and achieve the effect of neutralizing the dust and impurities in the waste gas.

[0003] In addition, in order to improve the treatment effect of waste gas, the waste gas recovery towers on the market usually use filters for filtering and adsorption operations. However, most of the adsorption components on the waste gas recovery towers use a single adsorbent for adsorption. The adsorption effect of a single adsorbent is limited and it is easy to saturate, which is not conducive to recycling. In addition, the waste gas recovery tower is generally closed, and it is difficult to replace the adsorbent in time. When the adsorbent is saturated, it will affect the adsorption effect, which brings inconvenience to the user. In view of this, we proposed a multi-stage adsorption component for the waste gas recovery tower. Utility Model Content
