Split self-circulation chemical synthesizer

Abstract

The invention discloses a split self-circulation chemical synthesizer and relates to a chemical synthesis reactor. A heat exchanger and a reactor form a self-circulation system, wherein the heat exchanger consists of a down pipe and a shell; a cooling chamber is formed by an inner space of the shell; the down pipe is arranged in the cooling chamber; the reactor consists of an upper end head, a wall body, a lower end head, a gas-liquid separator, a gas-collecting hood and a preheating chamber; the upper end head is arranged at an upper opening of the wall body; the lower end head is arranged at a lower opening of the wall body; the upper end head and an inner space defined by a middle section and an upper section of the wall body form a reaction chamber; the lower end head and an inner space defined by a lower section of the wall body form a gas-liquid separation chamber; a clapboard is arranged between the reaction chamber and the gas-liquid separation chamber for isolating; a circulating gas input opening is formed in the clapboard. The automatic circulation is realized by the chemical synthesizer under inner isobaric conditions, and a target product is timely separated, so that raw material gas can be totally synthesized into the target product through one-step compression only, the power consumption is greatly reduced, and the catalytic efficiency is improved.

Description

technical field [0001] The invention relates to a chemical equipment, in particular to a chemical synthesis reactor. Background technique [0002] 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, the mixed product must be output from the synthesis reactor and new raw material gas must be added to the synthesis reactor to make the target in the synthesis reactor After the product concentration is reduced and the balance is broken, the combination reaction continues. After the mixed product is output from the synthesis reactor, the unreacted gas is separated through the separation equipment, and then the unreacted gas is returned to t...

Problems solved by technology

[0004] The purpose of the present invention is to overcome the disadvantage that the existing chemical synthesis equipment needs to repeatedly cycle and compress the raw material gas and consume a large amount of electric energy, and design a split type self-circulating chemical synthesizer, which automatically circulates to carry out the chemical synthesis reaction by the chemical synthesizer itself. The raw material gas can be completely synthesized into the target product only through one compression, so as to greatly reduce power consumption and improve catalytic efficiency, and realize energy saving and reduction in the production of synthetic ammonia, methanol, dimethyl ether and other production processes that require chemical synthesis.
