Description

Technical Field

[0002] Chlorine is widely used in human production and life, especially in the chemical industry where it is an important raw material. However, chlorine is toxic and highly irritating, which has a serious impact on human health. The treatment of chlorine-containing waste gas is mainly done through wet purification, generally using chemical neutralization, oxidation-reduction and other processes to absorb chlorine and achieve comprehensive utilization.

[0003] Chlorine is a yellow-green gas with a suffocating odor at room temperature. It is poisonous. Chlorine is a strong irritant to the human respiratory organs and can be fatal if inhaled too much. Chlorine is heavier than air, about 2.5 times heavier than air. Chlorine can dissolve in water. After chlorine dissolves in water, it reacts with water to produce hydrochloric acid and hypochlorous acid. Therefore, chlorine water is extremely corrosive.

[0004] In the production process of trichloroisocyanuric acid, the chlorine gas produced by dechlorination is absorbed and reused by trisodium salt. However, when the reaction time between chlorine gas and trisodium salt is short, it is difficult to effectively react and absorb the chlorine gas, which has certain shortcomings.
