Absorption solution for rubber mixing waste gas treatment and preparation method and application thereof

Abstract

The invention relates to an absorption solution for rubber mixing waste gas treatment and a preparation method and application thereof. The absorption solution comprises an oxidizing agent and an activating agent; the oxidizing agent is selected from magnesium hydroxide, aluminum hydroxide, zinc hydroxide, iron hydroxide and the like; the activating agent is soluble salt capable of being dissolvedin water and can generate CO3<2->, HCO3<->, SO4<2->, HSO4<->, SCN<->, PO4<3->, HPO4<2->, H2PO4<->, HSiO3<-> or SiO3<2-> in the water. In one preferable mode of execution, for carbon black and other solid particle pollutants in rubber mixing waste gas, magnetic nanoparticles wrap the solid particle pollutants, and then the solid particle pollutants wrapped with the magnetic nanoparticles are combined with each other and condensed and fall based on the principle of magnetism, thereby achieving the effective removal of the solid particle pollutants.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to an absorption liquid used for treating waste gas from rubber banburying, its preparation method and application. Background technique [0002] During the production of rubber tires, a certain amount of exhaust gas is produced. The pollution factors of this kind of exhaust gas are mainly industrial dust (solid particles, etc.), odor (gas pollutants, etc.) and other pollutants. The malodorous components will cause certain pollution to the surrounding environment and the environment of the factory area, and it is inevitable to disturb the residents. The flue gas produced in the production process of the banburying workshop and the vulcanization workshop, which contains H 2 S, NH 3 , Organic sulfides, mercaptans, amines and other trace organic component gases not only cause direct harm to the health of operators, but also pollute the surrounding atmospheric environment, and waste ...

Problems solved by technology

[0012] However, the treatment objects of this existing absorbent are only sulfides and nitrogen oxides, but due to its particularity, waste gas from rubber banburying contains not only sulfides and nitrogen oxides, but also solid particles (such as carbon black), amines, Odor substances such as ammonia gas, these substances cannot be effectively removed by the above absorbents due to their chemical properties
