Double-cone atomization gas-liquid reactor

Abstract

The invention provides a double-cone atomization gas-liquid reactor, which belongs to the technical field of chemical equipment. A shell of the reactor is of a top-bottom double-cone structure; a jacket is arranged out of the shell of the reactor; a liquid phase inlet pipe is arranged at the top of the shell of the reactor, and an inlet end of the liquid phase inlet pipe is provided with a solid cone-shaped nozzle; the lower part of the shell of the reactor is provided with a gas phase inlet pipe, and an inlet end of the gas phase inlet pipe is provided with a disc-like gas phase distributor; and a liquidometer is arranged out of an outlet pipe at the bottom of the shell of the reactor. With the double-cone atomization gas-liquid reactor provided by the invention, a dispersing effect of a gas-liquid material in the reactor is improved, liquid is completely atomized by using the nozzle, a gas-liquid exchange area is increased, a conversion rate of gas-liquid reaction is improved, generation of reaction by-products is reduced, reaction time is shortened, polymerization of thermosensitive substances is effectively prevented, operation is easy and convenient, and reaction security is substantially improved.

Description

technical field

[0001] The invention belongs to the technical field of chemical equipment, and in particular relates to a double-cone atomization gas-liquid reactor. Background technique

[0002] At present, gas-liquid phase chemical reactors for heat-sensitive materials mainly include tower reactors, tank reactors and membrane reactors. Tower reactors mainly include packed tower reactors and plate tower reactors, but the cost of packed tower reactors is high , the cost of the plate tower reactor is not low, and it has the disadvantages of large gas phase flow pressure drop and small mass transfer surface; the membrane reactor has high requirements on the reaction medium, and its applicability is relatively poor; the gas-liquid phase contact efficiency of the tank reactor Poor, the reaction conversion rate is low, the reaction time is long, it is easy to cause the polymerization of heat-sensitive substances, and produce more by-products.
