Equal-pressure self-circulation chemical synthesizer

Abstract

The invention discloses an equal-pressure self-circulation chemical synthesizer and relates to a chemical-synthesis reactor. The equal-pressure self-circulation chemical synthesizer comprises a reaction chamber, an upper gas chamber, a cooling water distributing box, a cooling pipe bundle, a cooling water collecting box, a descending channel, a lower gas chamber and a shell, wherein the reaction chamber, the upper gas chamber, the cooling pipe bundle, the descending channel and the lower gas chamber are arranged in an inner space of the shell; the upper gas chamber is arranged above the reaction chamber; the lower gas chamber is arranged below the reaction chamber; the descending channel is arranged on the outer periphery of the reaction chamber in an enclosing manner; the reaction chamber is communicated to the upper gas chamber which is communicated to the lower gas chamber by the descending channel; the wall body of the reaction chamber is connected to the shell by supporting pieces; a circulating gas input port and a catalyst discharging port are formed in the lower part of the side wall or the bottom part of the arc of the wall body; a material gas-supplementing joint is connected into the lower gas chamber, the lower part of the lower gas chamber is provided with a liquid collecting area and a product outlet is formed in the bottom part of the liquid collecting area. The equal-pressure self-circulation chemical synthesizer disclosed by the invention has the advantages that the used amount of the materials of the wall body of the reaction chamber is reduced; the feed gas can be completely synthesized into a target product only by once compression, so that the consumption of electric energy is greatly reduced and the catalytic efficiency is greatly reduced.

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 shortcomings of the existing chemical synthesis equipment that the raw material gas needs to be repeatedly cycled and compressed to consume a large amount of electric energy, and to design a chemical synthesizer that automatically circulates and catalyzes the synthesis reactor itself, so that the raw material gas only needs to All of them can be synthesized into target products through one compression, so as to greatly reduce power consumption and improve catalytic efficiency, and realize energy saving and emission reduction in the production of synthetic ammonia, methanol, dimethyl ether and other production processes that require chemical synthesis.
