Overview

Distillation kettle is the core equipment for evaporation operation, which vaporizes the material solvent through heating, providing steam or concentrated products for distillation and concentration, and is applied in the chemical, pharmaceutical, and food industries. The structure of $r $n can be divided into three categories: simple jacket type, small heating area, suitable for small-scale production; Snake tube type increases surface area through snake shaped tubes, suitable for small and medium-sized low heating needs; Tube heating has a large surface area and high heat transfer efficiency, making it the mainstream of large-scale production. The operation of $r $n mainly relies on indirect heating. The heating agent transfers heat through a jacket or heating tube, and the solvent vaporizes to form secondary steam (cooled by a condenser). The concentrated material is discharged from the lower end.

Product Details

Distillation kettleIt is a reaction vessel used for evaporation operations, mainly used to vaporize the distilled liquid and provide upward steam for the working tower. Here is a detailed introduction:

structural type

Jacket type: The evaporation kettle has a sandwich layer, and the generated steam enters the outer sandwich layer of the kettle to heat the internal materials. The structure is simple, the heating area is small, and it is generally used for small-scale production.

Snake tube type: The heating tube is arranged in a snake shape inside the kettle, which can increase the heating area. It is commonly used in small devices and is suitable for situations where the heating requirements for materials are not particularly high.

Tube type: composed of a tube bundle and a shell, etc. The tube bundle has two channel ports on the same tube plate, with a large heating area and high heat transfer efficiency, and is often used in large-scale production.

working principle

Distillation kettleIndirect heating is usually used, and the heating agent is usually saturated water vapor with a certain pressure. Organic heat carriers with higher boiling points or electric heating can also be used as needed. Steam is introduced into the interlayer or heating tube outside the kettle, and heat is transferred to the materials inside the kettle through thermal conduction, causing the solvent in the materials to vaporize. The secondary steam formed is cooled by the condenser, and the concentrated materials are discharged from the lower discharge port.

feature

Wide scope of application: it can deal with materials of different properties, such as falling film evaporation kettle, which can deal with materials with high concentration and viscosity, and it is also suitable for evaporation and concentration of foaming materials to avoid the formation of foam.

High heat transfer efficiency: Some evaporation kettles, such as falling film evaporators, have a high heat transfer coefficient as the solution flows in a film like manner in a single pass evaporator.

Strong adjustability: The heat exchange area of the equipment can be adjusted, and the most suitable heat transfer effect and capacity can be obtained by adjusting the number of heat exchange plates or changing the process.

Application field

Evaporation kettles are widely used in industries such as chemical, pharmaceutical, and food. For example, in the pharmaceutical industry, they are used for evaporating and concentrating high salt water. When the high salt water is supersaturated, the concentrated crystal slurry is discharged from the lower discharge port; Used in distillation operations in chemical production to provide the necessary amount of rising steam in the tower.
