[0002] In chemical production and many industrial fields involving liquid chlorine use, efficient use and environmental protection of liquid chlorine have been a key problem, and traditional liquid chlorine reaction equipment often has many defects, which also causes certain environmental pollution.

[0003] In the reaction process of liquid chlorine, most traditional equipment lacks effective liquid chlorine dispersion mechanism, and liquid chlorine usually enters the reaction system in a relatively concentrated manner, which limits its contact area with the reaction liquid. Due to insufficient contact, the reaction rate is difficult to improve, and the initial reaction efficiency of liquid chlorine is low. A large amount of liquid chlorine cannot fully participate in the conversion in the initial reaction, which not only causes waste of raw materials, but also increases the cost and difficulty of subsequent processing.

[0004] The traditional reaction equipment is not perfect for the recovery design of reaction liquid chlorine, and the unreacted liquid chlorine in the reaction process cannot be effectively recycled. There is a lack of a special circulating system to promote the liquid chlorine to react with the reaction liquid again, which makes the liquid chlorine remain in the reaction system, reduces the overall recovery efficiency, and brings great pressure to the subsequent tail gas treatment link, further aggravating the risk of resource waste and environmental pollution.

[0005] In summary, in order to overcome the many drawbacks of traditional liquid chlorine reaction equipment, it is urgent to provide a liquid chlorine secondary recovery reaction equipment that can improve the initial reaction efficiency of liquid chlorine, improve the overall recovery efficiency, ensure the stability of the reaction and the quality of the product, to meet the efficient and environmentally friendly needs of industrial production.
