A kind of intake device of methyl chloride reaction tower

Abstract

The invention discloses an air intake device of a methyl chloride reaction tower, which includes a tower body and a sealed reaction barrel fixedly connected to the tower body; an air inlet pipe A, one end of which is fixedly connected to the upper part of the reaction barrel, and the other end extends Out of the tower body; air inlet pipe B, one end is fixedly connected to the lower part of the reaction barrel, and the other end extends out of the tower body; multiple connecting pipes C, one end is fixedly connected to the reaction barrel, and the other end is fixedly connected to the middle of the arc-shaped outlet pipe D , the connecting pipe C is located between the air inlet pipe A and the air inlet pipe B, and is distributed along the circumference of the reaction barrel. Both ends of the air outlet pipe D are provided with air outlets, and the air outlets of two adjacent air outlet pipes D are oppositely arranged.

Description

technical field [0001] The invention relates to an air inlet device of a methyl chloride reaction tower. Background technique [0002] The air inlet device is an important part in the reaction tower. The air inlet device can cut the whole gas introduced from the outside, so that the gas is evenly and finely distributed in the reaction tower, and it can also prevent the generation of large bubbles and prevent the bubbles from bursting. It causes vibration and plays a certain role in the stability of the reactor. [0003] The structure of an inlet device affects the distribution of the gas, which determines the degree of contact between the two substances, which in turn affects the efficiency of the reaction. Therefore, the performance of an air intake device determines whether the chemical reaction can be fully carried out, and determines the level of reaction efficiency. [0004] There are two inlets for the methyl chloride reaction tower, one inlet for methanol gas, the o...

AI Technical Summary

Problems solved by technology

[0004] There are two air inlets of the methyl chloride reaction tower, one inlet for methanol gas, and one inlet for hydrogen chloride gas. The air inlet device of the traditional methyl chloride reaction tower is made separately, each inlet There is one air intake device, one tower needs to make two air intake devices separately, the workload of making two air intake devices alone is heavy, and each air intake device needs to be fixed separately in the tower, increasing the support in the tower The number of welds increases accordingly

Moreover, the appearance of each air intake device is a circular tube type, and the gas divergence can only be diverged from the surface of one circular tube, and the divergent area is too small. Although several concentric circular tubes are made in the tower to increase the divergent area, this is undoubtedly Increased processing volume

[0005] The reaction area between the two inlet devices is too open, and it cannot ensure that the gas coming out of the upper and lower inlet devices can fully contact and react. Sometimes there may even be a problem that the gas flowing upward at the bottom cannot flow downward with the upper inlet hole. The gas meets to form convection, which causes the raw material gas to directly enter the product gas, and the product has a high impurity content, which increases the workload for the subsequent process of impurity removal

[0006] Moreover, hundreds of thousands of air outlets will be processed on the round pipe, and the outer surface of the round pipe is arc-shaped, and drilling holes on the arc-shaped surface is inconvenient to operate, and the manufacturing process is poor.
