Description

Technical Field

[0001] The utility model relates to the technical field of polyaluminium chloride preparation, and more specifically to a polyaluminium chloride reaction device. Background Art

[0002] Polyaluminium chloride is a commonly used inorganic polymer coagulant with strong flocculation and precipitation capabilities, and is widely used in the field of water treatment. It usually exists in the form of powder or liquid, and can effectively remove suspended matter, organic matter and colloids in water, so as to purify and improve water quality. Polyaluminium chloride plays an important role in sewage treatment, drinking water treatment, industrial wastewater treatment and other fields, and is an important water treatment agent.

[0003] The polyaluminium chloride reaction unit is a device used to produce polyaluminium chloride, which usually includes a reactor, a stirring device, a feed pipe, a heating / cooling system and other components. In the production process of polyaluminium chloride, the aluminium chloride solution is reacted with hydrogen chloride gas or hydrochloric acid to produce a polymer solution. The reaction unit can select different specifications and process parameters according to the needs to ensure the stability and efficiency of the production process. Through the polyaluminium chloride reaction unit, the production and supply of polyaluminium chloride, a high-efficiency coagulant required in the water treatment field, can be achieved.

[0004] The existing polyaluminium chloride reaction device will volatilize a lot of hydrochloric acid gas during the reaction. The hydrochloric acid gas is directly discharged into the air, which may affect the surrounding environment and may also cause waste of resources. When stirring, most of the existing polyaluminium chloride reaction devices lack a heating device, so that the reaction temperature is low, which may cause the reaction degree to be low, affecting the preparation effect of polyaluminium chloride. At the same time, most of the heat-conducting rods are fixed structures, resulting in poor replacement and maintenance effects. For this reason, we propose a polyaluminium chloride reaction device.
