Multi-group layered submerged impinging steam reactor

Abstract

The invention discloses a multi-group layered submerged impinging steam reactor and relates to a chemical reactor. The reactor is of a multi-group layered structure; top, middle and lower three layers of feed pipes are arranged on a reactor body; the feed pipes on the same layer are coaxially and oppositely arranged; the outlet end of each feed pipe is provided with a nozzle adjustable in structure, diameter and spacing; the reactor body is in the shape of a vertical cylinder; the upper end of the reactor body is provided with an elliptical head cover; a gas outlet, a pressure gage insertion hole and a temperature gauge insertion hole are formed in the elliptical head cover; the lower end of the reactor body is a conical reactor bottom, and a discharge hole is formed in the reactor bottom; an overflow outlet is formed in the side wall of the upper part of the reactor body, and can be used for leading out light components after reaction; the outer side of a column wall is provided with a jacket, and the jacket is used for heating or cooling. When the reactor works, fluid is sprayed through the nozzles of the feed pipes, and violently impinges in an impinging area in the reactor body so as to achieve the goals of full mixing and full reaction; the radial liquid flow of the impinging fluid can impinge for the second time, so that the reaction (mixing) efficiency is improved. According to the reactor, the feed pipes can be increased or reduced by groups according to the actual requirement, and therefore multiple working conditions can be adapted; the reactor is convenient to install and low in maintenance cost.

Description

technical field [0001] The invention relates to a chemical reactor, in particular to a multi-component layered submerged impingement flow reactor. Background technique [0002] In the process of reaction, reaction-precipitation and crystallization in the liquid-liquid phase and liquid-solid phase system, the mixing state in the reactor, especially the microscopic mixing state at the molecular scale, has an important influence on the reaction effect. At present, the most commonly used equipment in industry is the stirred tank reactor. The disadvantage of this kind of reactor is that the back mixing in the reactor is not uniform, and the stirring efficiency is low. The impinging flow reactor is a new type of chemical reaction equipment. Compared with the traditional stirred tank reactor, it has the advantages of large material contact area and high heat and mass transfer efficiency. However, most of the current impinging flow reactors are equipped with a propeller structure i...

Problems solved by technology

However, most of the current impinging flow reactors are equipped with a propeller structure in the guide tube. Although the mixing efficiency is improved, there are still some shortcomings, such as the high manufacturing cost of the propeller, and the long-term operation is easy to wear and tear.

Although the traditional impingement flow reactor has a good mixing effect in the impact area, the mixing effect is poor or even impossible in the area outside the impact area.

However, most of the existing impingement flow reactors formed by the impact of the jet flow are simple two-nozzle opposed type, the effective area of ​​the impact area is small, the processing capacity is limited, and the advantages of the impingement flow cannot be fully reflected, which limits the application of the impingement flow technology in the industrial field. application
