Kettle external feed pipe kettle combined reaction process method

Abstract

The invention discloses a kettle external feed pipe kettle combined reaction process method and relates to a production device and a using method thereof in a chemical process. The device comprises pipe reactors, a pipe kettle connection pipeline, a kettle reactor, a kettle pipe connection pipeline and various accessories; the pipe reactors are hollow pipes, mixed components which have the disturbance action on fluid, or static mixers, and chemical fillers are arranged in pipes of the pipe reactors; a using method comprises the following steps that: materials to be reacted enter the pipe reactors, flow, are mixed and reacted, and transfer heat simultaneously, and materials flowing out of the pipe reactors enter the kettle reactor and are reacted continuously; materials in the kettle reactor circularly enter the pipe reactors so as to finish reaction; and the diameters and lengths of the pipe reactors are adjusted to ensure that reaction is only performed in the pipe reactors. The reaction devices ensure that materials participating in reaction are quickly mixed on feed parts and reaction heat is transferred timely, and defects of nonuniform concentration distribution and local overheating in the conventional kettle reactor can be overcome.

Description

technical field [0001] The invention relates to a chemical process method, in particular to a reaction device for enhancing mass transfer and heat transfer through enhanced mixing in the chemical production process and a use method thereof. The invention is also applicable to processes that only intensify mixing without chemical reaction. technical background [0002] The chemical reaction process is a process accompanied by energy, mass, and heat transfer. The equipment used to realize the chemical reaction process is called a reactor or a reaction device, and the commonly used reactor is a stirred tank reactor. Tank reactors can be used for batch or continuous reactions. When the tank reactor is used for the batch reaction of dropping feed, there is obvious local overheating (cold) and uneven concentration distribution in the tank; when it is used for continuous reaction, the concentration distribution and residence time of the materials participating in the reaction in ...

AI Technical Summary

Problems solved by technology

However, when the coil is installed to increase the heat transfer area, the diameter of the stirring blade is forced to decrease, the mixing effect is reduced, the heat transfer coefficient becomes smaller, and the overall heat transfer effect does not change significantly.

The above deficiencies lead to the impact of product quality and production capacity when using tank reactors
