Problems solved by technology

[0002] The structure of the existing gas-solidification chemical reactor used in the synthesis of ammonia or methanol is not reasonable. Due to the low temperature out of the tower, it can only produce 1.2-2.5Mpa saturated steam, and the resistance of the reaction gas flow is relatively large, and the cycle consumes more power. ,Room for improvement

Embodiment Construction

[0037] According to the drawings and the device of the present invention with the above structure, the top cover on the top of the outer cylinder 14 under pressure is shown in FIG. The number of caps is very small. It is only opened when the inner cylinder is assembled for the first time (including large, medium and small), and then only the medium and small caps are opened to fill catalysts or inspect and maintain internal parts.

[0038] There is a tee at the bottom of the reactor, which is composed of two compressed hollow short joints. The upper short joint 16 is welded to the bottom of the pressure outer cylinder 14. The lower short joint 20 is connected to the upper short joint with a flange. The lower part can be flanged or directly Welded connections to pipes or steam generators.

[0039] A packing seal 15 is added between the upper short joint 16 and the annular gap of the inserted unreacted gas inlet pipe, and a sealing packing 19 is added to the annular gap between ...

Abstract

A multi-segment chemical gas-solid reactor is composed of a pressurized external cylinder and a heated internal cylinder, which has three layers, two pot-shaped gas collectors between adjacent two layers, and two heat exchangers installed respectively in the centers of the second and the third layers. Its advantages are high purity of product, high grade of vapor and low airflow resistance.

Description

technical field [0001] The present invention relates to a multi-stage gas solidification chemical reactor for ammonia or methanol synthesis. Background technique [0002] The structure of the existing gas-solidification chemical reactor used in the synthesis and production of ammonia or methanol is unreasonable. Due to the low outlet temperature, only 1.2-2.5Mpa saturated steam can be produced, and the reaction gas flow resistance is large and the cycle power consumption is large. ,Room for improvement. SUMMARY OF THE INVENTION [0003] The technical problem to be solved by the present invention is that, aiming at the defects in the prior art, a multi-stage gas-solidification chemical reactor is proposed, which has a simple structure, a high net value of ammonia produced, and can produce superheated steam with higher temperature and pressure for energy utilization. High efficiency, low cycle power consumption, and significant energy-saving effect. [0004] The technical ...
