Embodiment approach

[0024] As an embodiment of the present invention, the inner bottom of the tank body 1 is fixed with evenly arranged spiral columns 9; the surface of the spiral column 9 is provided with evenly arranged openings 10, and the openings 10 are arranged obliquely; The bottom of the helical column 9 communicates with the heating layer 2 through the air port 18, and the heated air can enter the helical column 9 from the air port 18; during operation, the hot air enters the helical column 9 through the air port 18, and then enters from the opening 10 on the surface of the helical housing. In the tank body 1, in contact with the toluene liquid in the tank body 1, heat can be directly brought to the toluene liquid in the tank body 1, and at the same time, the toluene liquid can be stirred to make the toluene liquid fully mixed, which is conducive to improving the heating and evaporation effect; opening holes 10 is set obliquely, and the gas rushes out from the opening 10 to drive the near...

Abstract

The invention belongs to the technical field of purification tools in chemical engineering, and particularly discloses an environment-friendly methylbenzene distillation kettle. The distillation kettle comprises a tank body, a bracket, a feeding port, a collection box and a condensation column, and the surface of the tank body is wrapped with a heating layer; the surface of the heating layer is wrapped with a thermal insulation layer; the top of the tank body is communicated with the condensation column through a pipe, and the pipe adopts double-layer pipe design; the pipe is communicated withthe heating layer through an air passage; a first slide groove uniformly distributed is formed in the condensation column; an air inlet pipe is arranged in the first slide groove; an air feeding portis formed in the bottom of the right side wall of the condensation column; spiral columns uniformly distributed are fixedly connected with the bottom in the tank body, and open holes uniformly distributed are obliquely formed in the surfaces of the spiral columns; hydrophobic air guiding membranes are arranged at the open holes; the bottoms of the spiral columns are communicated with the heatinglayer through air holes. The environment-friendly methylbenzene distillation kettle is simple in structure and can achieve uniform mixed heating; the inner wall of the tank body is cleaned; the environment-friendly methylbenzene distillation kettle is convenient to use and high in practicability.

Description

technical field [0001] The invention belongs to the technical field of chemical purification tools, in particular to an environment-friendly toluene still. Background technique [0002] Toluene is widely used as a solvent and high-octane gasoline additive, and is also an important raw material for organic chemicals. A series of intermediates derived from toluene are widely used in the production of fine chemicals such as dyes, medicines, pesticides, explosives, additives, and spices. , Also used in synthetic materials industry. Benzyl chloride, benzyl dichloride and benzyl trichloride obtained by side chain chlorination of toluene, including their derivatives benzyl alcohol, benzaldehyde and benzoyl chloride (generally also obtained from phosgenation of benzoic acid), are used in medicine, pesticides , dyes, especially perfumes are widely used in synthesis. The ring chlorination products of toluene are intermediates of pesticides, medicines and dyes. Toluene is oxidized t...
