Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to a technical field of nitrogen monoxide recovery, especially to a nitrogen monoxide recovery device. BACKGROUND
[0002] Nitrogen monoxide, commonly known as laughing gas, has the chemical formula N2O, and is widely used in industry due to its anesthetic, oxidizing and combustion-supporting effects. However, nitrogen monoxide is also a greenhouse gas, and directly discharging byproduct waste gas containing nitrogen monoxide into the air will cause serious greenhouse effects. For environmental protection purposes, it is necessary to recover and purify nitrogen monoxide for reuse. Currently, when existing nitrogen monoxide recovery devices purify nitrogen monoxide, they react the recovered nitrogen monoxide with a reaction solution. However, because the overall gas flow rate is high during the reaction of the gas with the reaction solution, it is difficult to completely adsorb the impurity gas wrapped in the target gas, which leads to insufficient reaction of the gas with the reaction liquid and low purification efficiency.
