Waste treatment device for acetamide production

Abstract

The invention discloses a waste treatment device for acetamide production. The waste treatment device comprises a treatment box. The outer wall of the treatment box is connected with a first heat preservation plate. A fixing box is connected to the top end and the bottom end of the treatment box. A rotation motor is connected to the inner wall of the top end of the fixing box. The output end of the rotation motor is connected with a rotation shaft. A connecting plate is vertically welded to the end, away from the rotation motor, of the rotation shaft. Stirring plates are vertically welded to the two side walls of the connecting plate. Symmetrically-arranged through holes are formed in the two side walls of the fixing box. The end, close to the connecting plate, of each through hole is internally connected with a filter net. One end of each through hole is connected with a first air suction pipe, wherein the first air suction pipe communicates with the through hole, the end, away from the through hole, of the first air suction pipe is vertically connected with a second air suction pipe, and the end, away from the first air suction pipe, of the second air suction pipe is connected with a fixing pipe. By means of the waste treatment device, heat of the waste can be rapidly collected and treated, the collected heat is used for acetamide production or other aspects, and resource waste is prevented.

Description

technical field [0001] The invention relates to the technical field of acetamide production, in particular to a waste treatment device for acetamide production. Background technique [0002] Acetamide is also known as acetamide. The chemical synthesis process of acetamide is mainly the dehydration of acetic acid and ammonia. It can also be obtained by the action of acetyl chloride, acetic anhydride or ethyl acetate and ammonia. [0003] In the production process of acetamide, some wastes will be produced before 210°C, and these wastes will be recycled. These wastes are often directly cooled in the end, and then the useful materials in the wastes are selected. When these wastes are just recycled, It itself has a lot of heat, if it is directly cooled, it will lead to waste of heat, so we propose a waste treatment device for acetamide production. Contents of the invention [0004] The purpose of the present invention is in order to solve the shortcoming that exists in the pr...
