Description

Technical Field

[0001] The utility model relates to the technical field of fly ash waste gas treatment, in particular to a waste gas treatment device in a fly ash treatment process. Background Art

[0002] The waste gas treatment device in the fly ash treatment process is a common industrial environmental protection measure, which usually involves the removal of particulate matter in the waste gas and the conversion or absorption of harmful gases.

[0003] At present, in the process of fly ash treatment, the existing waste gas treatment devices often use a fixed washing box as a preliminary treatment method, especially when treating waste gas containing a large amount of particulate matter. The design of the fixed washing box limits the fluidity of the washing liquid and the contact area with the waste gas, resulting in poor washing effect. When the waste gas contains a large amount of particulate matter, it is difficult for the fixed washing box to completely capture and remove these particles, so that the pollutants in the waste gas cannot be fully cleaned and removed; secondly, due to the limited contact area between the washing liquid and the waste gas, and the short residence time of the waste gas in the washing box, the pollutants in the waste gas cannot be fully treated, which not only affects the emission quality of the waste gas, but also increases the difficulty and cost of subsequent treatment. Therefore, the utility model provides a waste gas treatment device in the process of fly ash treatment. Utility Model Content
