Gas-liquid reaction distribution stirring device

Abstract

The invention relates to a gas-liquid reaction distribution stirring device which comprises a cover-shaped rotary table and an air inlet pipe, wherein a table body of the cover-shaped rotary table is provided with a group of air holes; the cover-shaped rotary table is rotatably arranged at the upper end of the air inlet pipe in a coaxial way; the side wall of the air inlet pipe is provided with a plurality of rows of air outlet branch pipes; the air outlet branch pipes are respectively communicated with the air inlet pipe and are arranged in the cover-shaped rotary table; the inner side wall of the cover-shaped rotary table is provided with a group of baffles; each group of air outlet branch pipes correspond to one baffle. The gas-liquid reaction distribution stirring device is ingenious in design and reasonable in structure; the distribution stirring device takes airflow shock as powder, and is environmentally friendly and free from energy consumption in the working process, so that the production cost is lowered, and the device is in accordance with the trend of energy conservation and environmental protection. Furthermore, after the distribution stirring device is adopted, the contact probability of gas and liquid at the bottom of a reaction tower can be increased, so that a reaction effect is improved.

Description

technical field [0001] The invention relates to auxiliary equipment in the field of gas-liquid reaction, in particular to a gas-liquid reaction distribution stirring device. Background technique [0002] Gas-liquid reaction is a very common reaction in chemical production. For example, the production method of benzoic acid is to add toluene solution into the reaction tower, and then feed air into the reaction tower for oxidation and catalytic reaction, and finally generate benzoic acid. The gas-liquid reaction is usually completed in the reaction tower. In the existing reaction tower, a gas distributor is installed at the lower part of the tower body and air is introduced. Since the existing gas distributor mainly relies on gas injection, the gas-liquid mixing effect is poor. , the formed bubbles are larger and less, and the gas-liquid contact surface area is less, resulting in incomplete reaction, which ultimately affects product quality and production speed. If the apertu...

The gas-liquid reaction is usually completed in the reaction tower. In the existing reaction tower, a gas distributor is installed at the lower part of the tower body and air is introduced. Since the existing gas distributor mainly relies on gas injection, the gas-liquid mixing effect is poor. , the formed bubbles are larger and less, and the gas-liquid contact surface area is less, resulting in incomplete reaction, which ultimately affects product quality and production speed

If the aperture of the inlet pipe outlet is reduced and high-pressure air is injected, although small bubbles can be produced, the resistance and energy consumption are large, and it is difficult to realize

At present, the applicant has developed a new type of gas distributor, which can ensure the gas-liquid reaction effect, but because it uses a motor to provide power, there is energy consumption
