Methanol synthesis reactor structure

Abstract

The invention relates to a methanol synthesis reactor structure which comprises a tube body, an upper sealing head and a lower sealing head and is characterized in that a water inlet tank and a water outlet tank separated with the inner wall of the tube body through gaps are arranged in an inner cavity of the tube body. A water inlet pipe penetrates through the bottom surface of the water inlet tank to be communicated with an inner cavity of the water inlet tank, and the water outlet pipe penetrates through the top surface of the water outlet tank to be communicated with an inner cavity of the water outlet tank. A plurality of tube holes corresponding to a heat exchange pipe are arranged on the top surface and the bottom surface of the water inlet tank, the heat exchange pipe is of a straight line structure, and two ends of the heat exchange pipe are respectively inserted into the corresponding tube holes on the water inlet tank and the water outlet tank so that the water outlet tank is communicated with the water inlet tank. Compared with the prior art, the water inlet device and the water outlet device are of tank body structures, the surfaces of end faces of the structures connected with the heat exchange pipe adopt flat plate structures, and the end portion of the heat exchange pipe needs no bending and can be conveniently welded onto an annular tube pipe, so that manufacturing and processing difficulty of the reactor is reduced, and processing accuracy is high.

Description

technical field [0001] The invention relates to the field of chemical equipment, in particular to a methanol synthesis reactor structure. Background technique [0002] Methanol is an important organic chemical raw material and clean liquid fuel, and it is also the basis of carbon-one chemistry. The methanol-to-olefins technology has opened up a production route for producing low-carbon olefins from non-petroleum raw materials. The industrialization of this technology can reduce the excessive dependence on petroleum resources and is of great significance to the balanced and rational use of resources in our country. [0003] Methanol synthesis reactor is the heart equipment of methanol production. In recent years, large-scale methanol plants built or under construction in China have basically adopted foreign technology and key equipment, such as Lurgi methanol synthesis reactor, Davy radial flow methanol synthesis reactor and ICI multi-stage cold shock methanol synthesis reac...

AI Technical Summary

Problems solved by technology

[0010] In the domestic traditional radial flow methanol synthesis reactor, the heat exchange tube is connected with the upper and lower ring pipes after special bending. The connection and welding of the heat exchange tube and the ring pipe are difficult to ensure the quality; There are many processes; the heat exchange tube holes on the ring tube are difficult to process and the accuracy is not easy to guarantee; and it is inconvenient to install tube bundle supports, which affects the service life of the catalyst and the concentration of methanol at the outlet; leakage occurs at the joint, which is difficult to repair, etc.

Only suitable for small methanol reactors, not easy to enlarge

[0011] Therefore, the existing single methanol synthesis reactor is more suitable for small methanol reactors and is not easy to be enlarged
