Description

Technical Field

[0001] The utility model relates to the technical field of wastewater treatment equipment, and specifically relates to a wastewater treatment device for the production of chlorinated polyvinyl chloride. Background Art

[0002] Chlorinated polyvinyl chloride (referred to as PVC for short) is an important plastic material, which is widely used in the fields of construction, packaging, agriculture, etc. Its production process mainly includes steps such as polymerization, rectification, and granulation. In these processes, the heating and mixing of raw materials and the use of catalysts will all cause a large amount of wastewater to be generated.

[0003] If these wastewaters are not properly treated, they will cause serious pollution to the environment. Therefore, it is very necessary to use a wastewater treatment device to treat the wastewaters generated in the production process of chlorinated polyvinyl chloride. The existing wastewater treatment devices for the production of chlorinated polyvinyl chloride mainly rely on two processes of mixing and filtration, but these two processes are not integrated, resulting in low treatment efficiency. In the mixing stage, the wastewater reacts fully with chemical agents to remove pollutants. However, the filtration link faces many challenges. The existing filtration device is inconvenient in design and the filter frame cannot be easily disassembled, which makes regular cleaning and maintenance difficult. As the use time prolongs, the filter screen is easily blocked by impurities, thereby reducing the filtration effect, increasing the operation cost and downtime. This single treatment method not only affects the overall efficiency of wastewater treatment, but also may lead to a decrease in the treatment compliance rate. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a wastewater treatment device for the production of chlorinated polyvinyl chloride, so as to solve the problems put forward in the above background art.
