Technical Field

[0001] The utility model belongs to the technical field of absorption towers, and in particular relates to a circulating spray absorption tower for formaldehyde production. Background Art

[0002] The circulating spray absorption tower is a commonly used gas purification equipment. Waste gas containing harmful tail gas will be generated during the production of formaldehyde solution. The circulating spray absorption tower is used to control and treat the gas emitted after the production of formaldehyde solution. This equipment is usually used to control the emission of sulfur dioxide, nitrogen oxides and other harmful gases and convert them into harmless gases. This equipment pumps the treated gas back into the spray system and adds water to it to absorb pollutants, and then releases the clean gas into the atmosphere.
