Description

Technical Field

[0001] The utility model belongs to the technical field of antioxidant BHT production, and specifically relates to a waste liquid treatment device. Background Technique

[0002] In the production process of antioxidant BHT (butylated hydroxytoluene), waste liquid treatment is a key link. Traditional waste liquid treatment methods often face problems such as low treatment efficiency, high energy consumption, unstable treatment effect, and easy generation of secondary pollution.

[0003] The utility model with the publication number CN220766639U discloses a waste liquid treatment device, including a first box body. Two support legs are installed at the bottom of the first box body, and a second box body is fixedly connected to the top. A worm is rotatably connected between the two support legs. A motor is fixedly connected to one side of one of the support legs. Through the stirring rods on the stirring shaft, the waste liquid and disinfectant can be fully stirred to make their mixing more uniform. Through the heating sheet, the waste liquid can be appropriately heated, further improving the sterilization and disinfection efficiency of the device, solving the problem that the waste liquid and disinfectant are not mixed evenly enough and the remaining bacteria will affect the environment. The structure is simple and practical. Through the brush, the impurities filtered by the filter plate can be cleaned to prevent the filter plate from being blocked easily due to excessive impurities over time. When too many impurities are filtered from the waste liquid by the filter plate, the filter plate can be easily taken out by pulling the pull rod, which can reduce the time consumed by the staff.

[0004] However, the above patent still has the following problems: During the treatment of waste liquid, due to the mechanical force generated by stirring and the physical properties of the waste liquid itself, some waste liquid may splash onto the inner wall of the tank, and after long-term accumulation, it will form stains that are difficult to remove, which not only affects the appearance of the equipment but may also become a breeding ground for bacteria, having a negative impact on the subsequent treatment effect. The device treats the waste liquid by steam heating, and this process will cause the temperature of the tank to rise. After the treatment is completed, the device often cannot cool down quickly, which not only affects the continuous use ability of the equipment but may also cause thermal stress damage to the equipment itself, making the use of the device inconvenient.
