Description
Technical Field
[0001] The utility model relates to the technical field of automobile parts processing and oiling, in particular to a waste gas treatment mechanism of a waste liquid tank used in the production of dimethylacetamide. Background Art
[0002] Waste gas treatment in waste liquid tanks refers to the treatment of waste gas generated in waste liquid tanks to reduce environmental pollution. Waste gas in waste liquid tanks usually contains harmful gases such as organic matter, ammonia, hydrogen sulfide, etc., which need to be treated before being discharged into the atmosphere. During the production of dimethylacetamide, a large amount of waste liquid and waste gas will be generated, which is difficult to treat.
[0003] In the production of dimethylacetamide, waste liquid and waste gas are generally treated by using waste gas tanks to collect waste gas and waste liquid. When this method is used, the waste gas and waste liquid are mixed together, and the subsequent treatment methods for waste gas and waste liquid are different, so secondary separation is required.
[0004] Therefore, we propose a waste gas treatment mechanism for a waste liquid tank used in the production of dimethylacetamide to solve the above problems. Utility Model Content
[0005] The utility model aims to provide a waste gas treatment mechanism for a waste liquid tank used in the production of dimethylacetamide. When the treatment mechanism is used, the waste gas and waste liquid generated in the production are firstly collected and recovered in the waste liquid tank, and then heated at the bottom of the waste liquid tank, so that part of the harmful substances in the waste liquid are scattered along with the hot gas generated by the heating into the waste gas separation port for liquid-gas separation. In the heating process, chemical additives are mixed into the waste liquid through an additive port arranged on one side, and quickly mixed by a stirring rod, and at the same time, heating is coordinated to improve the efficiency of evaporation, so that the harmful substances in the waste gas can be scattered and recovered in large quantities following the evaporation, so that a large amount of harmful substances can be taken away after the waste gas is recovered and treated, which can greatly improve the subsequent waste liquid treatment efficiency, and the waste gas recovered subsequently can also be centrally treated separately in other ways to solve the problems raised in the above-mentioned background technology.

[0009] In a further embodiment, the additive port crosses the outer wall of the waste liquid tank body, and an exhaust fan is provided on the upper side of the inner end.
[0010] In a further embodiment, the inner side of the push cylinder is provided with a hollow groove, and the bottom end of the hollow groove is inclined, and the opening of the hollow groove is smaller than the length of the solid wall provided at the lower end of the additive port.
