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 chemical purification tools, in particular to an environment-friendly toluene distillation kettle, comprising a tank body, a support, a feed port, a collection box and a condensation column, the surface of the tank body is wrapped with a heating layer; the heating The surface of the layer is wrapped with an insulation layer; the top of the tank body is connected to the condensation column through a pipeline, and the pipeline is a double-layer pipe design; the pipeline is connected to the heating layer through the air channel; there are uniformly arranged No. Chute; the No. 1 chute is provided with an air inlet pipe; the bottom of the right side wall of the condensation column is provided with an air inlet; the bottom of the tank is fixed with evenly arranged spiral columns; There are evenly arranged openings, and the openings are arranged obliquely; the openings are provided with a hydrophobic air-conducting film; the bottom of the spiral column communicates with the heating layer through the air port; the invention has a simple structure and can realize uniform mixing and heating; The internal wall is cleaned; it is convenient to use and has strong 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...
