Chemical acid gas absorption is an important waste gas treatment technology, mainly used for removing acid gas emissions generated in the chemical production process, such as sulfur dioxide, nitrogen oxides and the like. These acid gases have great harm to the environment and human health, so effective treatment is needed, and chemical acid gas absorption device needs to be used.
[0003] The existing chemical acid gas absorption device still has the following problems when in use:
[0004] (1) The existing chemical acid gas absorption device often has the problem of uneven spraying during spraying, because the spraying pipe is fixed, the distribution range of the spraying droplets is limited, and the entire gas treatment area cannot be fully covered, resulting in that part of the acid gas cannot be fully contacted with the spraying liquid, thereby affecting the absorption effect of the acid gas;
[0005] (2) The existing chemical acid gas absorption device often uses single filter material in the filtering link, and these filter materials have certain filtering effect, but they cannot completely remove harmful substances in the acid gas, especially for some small particles and harmful gas molecules, the filtering effect is limited.
[0006] Therefore, we improve it and propose a chemical acid gas absorption device. UTILITY MODEL CONTENT
