Problems solved by technology

[0005] The existing lye absorption desulfurization has a low removal rate, and the removal rate of hydrogen sulfide is only 70%; the desulfurization variety is single, only hydrogen sulfide can be removed, and organic sulfur such as mercaptan, sulfide, and dimethyl disulfide cannot be removed; desulfurization Sodium sulfide, the product after hydrogen, is unstable (easy to decompose), and it is easy to cause secondary pollution during waste residue treatment; the use time of alkali absorbent is short, and the effective use time is only 3 months; another alkali absorbent corrodes the equipment, which affects the utilization rate of equipment Wait

Abstract

The invention relates to a chemical absorbent, in particular to a chemical absorbent for deodorization. In order to overcome the technical problem, the invention proposes the technical scheme that the chemical absorbent consists of the following components in parts by weight: 10-20% of strong base, 5-7% of oxidant,0.2-0.5% of active agent, 0.05-2% of corrosion inhibitor, 0.05-2% of pour point depressant, 0.05-8% of desulfurizer, 0.05-4% of catalyst and 60-80% of water. The chemical absorbent has the advantages of overcoming the low removal rate of pure alkaline liquor to hydrogen sulfide in the prior art, improving the absorptivity of sulfur compounds in waste gas and removing organic sulfur, such as sulfur alcohol, sulfur ether, dimethyl disulfide, and the like. The waste residue of sodium sulfide which is generated after treatment is relatively stable and is easy to decompose, thereby avoiding secondary pollution. The chemical absorbent has longer use time than the traditional absorbent and high reaction speed in removing the sulfur compounds.

Description

technical field [0001] The invention relates to a chemical absorbent, in particular to a deodorizing chemical absorbent. Background technique [0002] Air is a necessary condition for human beings to survive. An average adult needs to inhale more than ten kilograms of air every day, which is several times more than the food and water requirements. Whether the air we inhale is fresh and clean is closely related to each of us. Polluted air entering the human body can cause respiratory, cardiovascular, nervous and other system diseases or other diseases. Odor pollution is a kind of sensory pollution that causes unpleasant feelings through people's sense of smell, and even affects human health. Volatile odorous molecules that are vicious and have a low olfactory threshold escape into the atmosphere, stimulating people's sense of smell, causing strong discomfort, dyspnea, anorexia and nausea, decreased digestive function, irritability, insomnia, and reduced work efficiency.
