Hydrothermal reaction kettle with flexibly arranged fins in kettle

Abstract

The invention provides a hydrothermal reaction kettle with flexibly arranged fins in the kettle. The hydrothermal reaction kettle comprises a stirring motor, a kettle lid, flanges, a reaction kettle body, a motor stirring rod, a stirring blade and the fins in the kettle; the reaction kettle body is provided with the matched kettle lid, and the stirring motor is arranged on the kettle lid; the motor stirring rod is hermetically and rotatably connected with the kettle lid, the top end of the motor stirring rod is connected with the stirring motor, and the lower end of the motor stirring rod is provided with the stirring blade; the reaction kettle body is internally provided with at least one fin in the kettle; the fins involve an annular inner ring, and the outer side wall of the annular inner ring is fixedly provided with multiple fin plates; the stirring blade is located in the annular inner ring; a distance is formed between the fin in the kettle at the lowermost portion and the bottom end in the reaction kettle body. The hydrothermal reaction kettle can arrange a certain number of fins in the kettle according to the quantity of reactants, thereby greatly improving the utilizationefficiency of the hydrothermal reaction kettle; the reaction kettle can also shorten the temperature rise time of the reactants and improve the uniform distribution degree of the reactants in the kettle.

Description

technical field [0001] The invention relates to the technical field of reactors, in particular to a hydrothermal reactor with flexibly arranged fins in the reactor. Background technique [0002] In actual production, the reactor is widely used in petroleum, chemical, rubber and food industries. Reactors can be divided into water heating reactors, steam heating reactors, other medium heating reactors and electric heating reactors. When the chemical reaction does not require too much temperature, water can be used to heat the reactor. The water heating reactor can be divided into two types: open type and closed type. When choosing a steam heating reactor as the reaction vessel, if the heating temperature is lower than 100°C, the normal pressure steam can be realized. If the heating temperature exceeds 180°C, it needs to be heated by high-pressure superheated steam. When the reaction needs to avoid a high pressure environment, other media can be used instead of water and ste...

Problems solved by technology

However, only through the rotating flow of reactants in the reactor, the heat transfer can only be improved to a certain extent, and the problem of uneven heating of the upper and lower parts of the reactants is prone to occur.

At the same time, the commonly used reactors still have the problem of low equipment utilization.
