Gas-liquid reaction method

Abstract

The invention discloses a gas-liquid reaction method. According to the method, feed gas from a previous working section enters a reaction kettle from the upper end of the reaction kettle, a gas inletpipe is not inserted into the kettle, the feed gas realize large-area contact with feed liquid, and a gas-liquid reaction occurs; as the feed gas has certain pressure and a stirring diffusion device with a drainage effect is arranged at the bottom of the reaction kettle, the feed gas can deeply enter the feed liquid for a continued reaction; and finally, unreacted gas along the gas flow enters anoutflow gas liquid insertion pipe having been inserted to a certain depth below the liquid level for a further reaction, and then the gas is introduced into a next-stage reaction kettle for a deep reaction or directly enters a tail gas treatment system through an exhaust pipe. The gas-liquid reaction method of the invention can realize continuous, stable, safe and efficient operation of a gas-liquid reaction.

Description

technical field [0001] The invention relates to a gas-liquid reaction method. Background technique [0002] Gas-liquid reaction is a relatively common reaction method in chemical production. The raw material gas (which can be single-component or multi-component) is used to insert the reaction liquid into the vent tube, and the gas-liquid contact will react. The defect is that the gas-liquid The contact surface is limited by the diameter of the insertion tube. If the gas-liquid reaction generates solid substances, it is very easy for the solid product to block the insertion tube, thereby affecting the continuous and stable production. In addition, because the raw material gas passes through the intubation tube Below the liquid level, if the intake pipeline is abnormally formed with negative pressure, etc., it is very easy to cause the risk of liquid pouring! The invention effectively solves the above disadvantages, and realizes continuous, stable, safe and efficient operatio...
