[0002] Polyaluminum chlorsulfide is a composite modified polyaluminum chloride with fast coagulation reaction speed, large fluffing, fast precipitation speed, strong adaptability to changes in raw water turbidity, and special effects in treating low-temperature, low-turbidity and high-turbidity water. It has a small dosage, is easy to operate and manage, and does not corrode dosing equipment and pipeline components. The product has stable quality, high purity, and extremely low insoluble matter content. It is a relatively common water treatment agent. The preparation of polyaluminum chlorsulfide generally needs to be carried out in a reactor.

[0003] Most traditional reactors use a single stirring plate for stirring, which has poor mixing effect and cannot ensure the full reaction of the liquid medicine, thus affecting the preparation efficiency of polyaluminum chlorosulfide.

After the reaction is completed, it is more troublesome to clean the inner wall of the reactor, which makes the cleaning of the reactor more labor-intensive and inconvenient for the preparation and use of polyaluminum chlorosulfide. Therefore, we need to design a more efficient and easy-to-clean inner wall integrated stirring and heating polyaluminum chlorosulfide reactor. Utility Model Content
