low temperature reactor

Abstract

The invention discloses a low-temperature reaction kettle which comprises a kettle body, a U-shaped jacket and a kettle cover, wherein a feeding hole A and a feeding hole B are formed in the upper end of the kettle body; a thermometer well stretches into the kettle body, and the upper end of the thermometer well is fixedly arranged on the kettle cover; the lower end of the feeding hole A is connected with a guide pipe; a pan-and-tilt-shaped protrusion part is arranged at the other end of the guide pipe; a chamber is formed in the protrusion part; the lower surface of the chamber is coated by a fine-pored meshed film; when the temperature is lower than a reaction temperature, pores of the meshed film are larger than the size of reactants; the kettle body comprises a cylinder and an elliptical lower seal head; the U-shaped jacket surrounds the cylinder and the elliptical lower seal head; a converging cone is arranged at the upper end of the U-shaped jacket; the upper opening of the cone is welded with the cylinder; a spirally ascending batten is wound around the outer wall of the cylinder; the inner edge of the batten is welded on the outer wall of the cylinder; and a radial gap is formed between the outer edge of the batten and the inner wall of the U-shaped jacket. According to the low-temperature reaction kettle, the reactants can be contacted at a specified temperature, the heat transfer area is large, the reaction of the materials in the kettle is convenient, the structural design is reasonable, and the concept is ingenious and novel.

Description

technical field [0001] The invention belongs to the field of mechanical accessories, and relates to a reaction kettle, in particular to a low-temperature reaction kettle. Background technique [0002] Reactor is one of the essential equipment in the production of chemical industry. As we all know, there are many kinds of reactors, which are widely used in petroleum, chemical industry, food, medicine, pesticide, scientific research and other industries. They are used to complete polymerization, condensation, vulcanization, Reaction equipment for chemical processes such as alkylation and hydrogenation. When the reactants in many reactors reach different temperatures, different products will be produced. Only when they are contacted at the specified temperature can the required products be produced, otherwise it will cause heavy losses. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention provides a low-temperature reaction ke...
