Description

Technical Field

[0001] The utility model relates to the technical field of chlorinated polyethylene production, in particular to a chlorinated polyethylene wastewater recovery device. Background Art

[0002] In the production process of chlorinated polyethylene by the aqueous phase method, the synthesized crude chlorinated polyethylene is successively subjected to the processes of deacidification, neutralization and dealkalization before entering into centrifugal drying to obtain the finished product. In the process of deacidification, neutralization and dealkalization, alkaline waste liquid and alkaline waste liquid will be generated. Direct discharge of the waste liquid will pollute the environment.

[0003] After searching, the utility model patent with announcement number CN218130207U discloses a recycling device for water used in the production of chlorinated polyethylene, including a recycling box, a feed port opened at the top of the recycling box, a feed pipe penetrating the feed port and inserted into the inside of the recycling box, and a discharge port opened at the side wall of the bottom end of the recycling box. The inner wall of the recycling box is fixedly connected with a filter layer, and the filter layer can be activated carbon, which can have a good effect of adsorbing impurities. The inner wall of the recycling box is rotatably connected with a rotating plate, and the outer wall of the rotating plate is fixedly connected with a plurality of groups of rotating rods; the recycling device for water used in the production of chlorinated polyethylene can drive the first rotating rod, the driving gear, the driven gear, the second rotating rod, the rotating plate and the rotating rod to rotate after starting the driving motor. At this time, the water left by the feed pipe will be scattered, and the water can be fully in contact with the filter layer to achieve a comprehensive filtering effect. This method can ensure that the water after circulation has a certain degree of cleanliness and enhance the use effect of the device.

[0004] However, the above patents still have the following shortcomings: it is only convenient for recycling water from water circulation equipment, but not convenient for collecting acidic waste liquid and alkaline waste liquid generated in the production process of chlorinated polyethylene. It is necessary to equip an additional collection device to collect acidic waste liquid and alkaline waste liquid, which has poor effect; and it is not convenient to automatically clean the impurities filtered from the filter layer, which easily leads to clogging of the filter layer and affects the filtering effect. For this reason, we propose a chlorinated polyethylene wastewater recovery device. Utility Model Content
