The invention discloses a self-circulation synthesis reaction system capable of performing separation and preheating through a refrigerating device, relating to a chemical synthesis reactor. The self-circulation synthesis reaction system mainly comprises a refrigeration device, a synthesis reactor and a downcomer assembly, wherein the refrigeration device consists of a refrigerating compressor, an evaporator and a condenser, the synthesis reactor consists of an upper end, a wall body, a lower end, a partition and an air distribution plate, the upper end is arranged on the upper opening of the wall body, the wall body has a cylinder structure, a reaction chamber and a heating chamber are formed in the inner space of the wall body, the partition is arranged between the reaction chamber and the heating chamber, the air distribution plate is arranged on the lower end of the heating chamber, the lower end is arranged on the lower opening of the wall body, and an air-liquid separation chamber is arranged in the inner space of the lower end; the condenser is arranged in the heating chamber, the evaporator is arranged in the air-liquid separation chamber, and the refrigeration compressor and the downcomer assembly are arranged outside the synthesis reactor. According to the self-circulation synthesis reaction system, separation of target products can be timely carried out inside the synthesis reactor, and raw material gas or unreacted gas can be preheated by virtue of condensation heat release of a refrigerant.

Description

technical field [0001] The invention relates to a chemical equipment, in particular to a chemical synthesis reactor. Background technique [0002] In the production process of chemical synthesis, it is necessary to heat the raw material gas. At an appropriate temperature, the compound reaction is easier to carry out and the catalytic efficiency is higher. The mixture of reaction gas, conventional synthesis reaction production is to take the mixture of target product and unreacted gas outside the reactor to take cooling and distillation measures to separate the target product. [0003] In the presence of catalysts, most chemical synthesis reactions are reversible reactions. When the target product reaches a certain concentration, it will be in equilibrium, and the reaction will no longer proceed in the direction of synthesizing the target product. In the production process of the compound reaction, in order to make the reaction continue to the direction of the target product...
