Abstract

The invention relates to a reaction tower for ammonia synthesis. Main components comprise an outer cylinder, a top cover, a tower top flange, a bottom cover, a tower bottom assembly, an inner cylinder, a catalyst basket, a casing pipe mechanism, a heat exchanger, heat exchange pipes, a circulation pipe, a product output pipe and a filter membrane. The upper end of the outer cylinder is connected to the top cover. The upper end of the top cover is connected to the tower top flange. The top cover is provided with a raw material inlet. The lower end of the outer cylinder is connected to the bottom cover. The lower end of the bottom cover is connected to the tower bottom assembly. The outer cylinder wraps the inner cylinder. The upper part of the inner cylinder is provided with the catalyst basket. The casing pipe mechanism is arranged at the lower end of the catalyst basket. The heat exchanger is arranged at the lower end of the inner cylinder. The heat exchanger is provided with the heatexchange pipes spirally and inclinedly distributed, the heat exchanger is provided with a circulation pipe, a product output pipe is arranged at the lower end of the heat exchanger and the filter membrane is arranged in the product output pipe. The reaction tower has the advantages of high ammonia synthesis conversion rate, compact structure, small floor space, neat internal structure, convenientmaintenance, energy saving, high ammonia separation efficiency and high ammonia quality.

Description

technical field [0001] The invention relates to a reaction tower for ammonia synthesis, which belongs to the field of ammonia synthesis. Background technique [0002] The conventional method of industrial ammonia synthesis is: under high pressure and high temperature, nitrogen and hydrogen are catalyzed to obtain ammonia. Because the process of synthesizing ammonia is carried out at high temperature and high pressure, the reaction is a reversible reaction, and both reactants and products are gases, so the control of reaction conditions is very critical to the reaction efficiency; in addition, the reaction is an exothermic reaction, the reaction process There is a large amount of heat of reaction released in the process, and the utilization of the heat of reaction is also very important. [0003] At present, the common problems of the existing ammonia synthesis towers are: the reaction conditions are not easy to control, the catalytic activity is low; the mass transfer resis...
