[0001] The utility model relates to the technical field of waste chemical raw material treatment, in particular to a waste liquid treatment mechanism. Background Technique

[0002] Triethylaluminum is extremely flammable, highly corrosive, highly irritating, and has very high chemical reactivity. It will smoke and ignite spontaneously when exposed to air; it is extremely sensitive to trace amounts of oxyhydroxide water and is prone to combustion and explosion; it will react violently with acids, halogens, alcohols, and amines; it will decompose strongly when encountering water, releasing flammable alkane gases.

[0003] In the prior art, the treatment method for waste triethylaluminum is to press the waste triethylaluminum into a first storage tank containing white oil through a protective gas for absorption to form a mixed liquid, and the mass fraction of triethylaluminum in the mixed liquid is less than 8%; after stirring the mixed liquid, it is left standing for a period of time; the mixed liquid in the first storage tank is sent to a second storage tank containing a protective gas near the combustion furnace through a protective gas, and the mixed liquid in the second storage tank is discharged into the combustion furnace for combustion.

[0004] However, when the mixed liquid is left standing after stirring, the mixed liquid is likely to remain on the inner wall of the tank body, and the stirring device lacks a scraping effect, which not only affects the treatment of triethylaluminum but also causes the subsequent use of the tank body. Therefore, it cannot meet the use requirements, so a waste liquid treatment mechanism is proposed to solve the problems raised above. Content of the Utility Model
