Description

Technical Field

[0001] The utility model relates to the technical field of sulfur-containing tail gas treatment devices, in particular to a sulfur-containing tail gas treatment device with adjustable air intake. Background Art

[0002] The sulfur-containing tail gas treatment device can effectively remove sulfides (such as hydrogen sulfide H2S, sulfur dioxide SO2, etc.) in the tail gas. These sulfides are one of the main sources of air pollution and have serious impacts on the environment and human health. Through the treatment device, the emission concentration of these harmful substances can be significantly reduced, thereby reducing pollution to the atmosphere.

[0003] According to a sulfur-containing tail gas treatment device disclosed on the patent website (authorization announcement number: CN 219964512U), "a sulfur-containing tail gas treatment device includes a purification tower for gas purification, a pressure-applying component arranged on the purification tower, and a catalytic unit installed in the purification tower; the purification tower includes a shell, and the outer side of the shell is provided with two pipe connection ports in a staggered mirror image, which are used to connect the pipeline for communicating gas; between the two pipelines, an area for installing the purification unit is provided on the inner side of the shell for gas treatment."

However, in actual use, since the size of the air inlet of the device cannot be adjusted, and when too much sulfur-containing exhaust gas enters the interior of the device, it is impossible to ensure that the exhaust gas has enough residence time in the treatment device, and harmful substances such as sulfides cannot fully react with the catalyst, further increasing the emission of pollutants that are not completely converted, which can easily make the desulfurization effect of the device poor. Therefore, it is necessary to improve a sulfur-containing exhaust gas treatment device with adjustable air intake. Utility Model Content
