Fluidized bed cluster reactor

Abstract

The invention discloses a fluidized bed cluster reactor, and relates to the field of gas-solid reaction fluidization equipment. An air inlet, an air outlet and a header wall are arranged in a header,and the header wall divides the header into a long cavity communicated with the air inlet as well as a small cavity communicated with a plurality of fluidized bed cluster adsorption beds; the air inlet is formed in the small cavity and is communicated with the long cavity, and the fluidized bed cluster adsorption bed comprises a plurality of bed tubes arranged side by side, a granular material anda leak-proof net; the air outlet is formed in the small cavity and directly faces the inlet end of the bed tube, the gas to be treated flows into the long cavity of the header through the air inlet,passes through an air distributor through the air outlet of the header to flow into the bed tubes of the fluidized bed cluster adsorption bed, and then flows to the air outlet through the leak-proof net and then leaves the reactor. The fluidized bed cluster reactor disclosed by the invention has the beneficial effects that the problems of high pressure drop in the reactor and serious wear of the granular material are solved, the utilization rate of the granular material in the reactor is improved, and the replacement cost of the granular material is reduced, thereby achieving the purposes of high efficiency, energy saving and cost reducing.

Description

technical field [0001] The invention relates to the field of gas-solid reaction fluidization equipment, in particular to a fluidized bed cluster reactor. Background technique [0002] Gas-solid fluidized reactors are widely used in the fields of heterogeneous catalysis and gas separation due to their advantages such as small gas resistance, sufficient gas-solid contact, and good heat and mass transfer performance. The pressure drop of the reactor is an important factor determining the efficiency of the gas-solid reaction and the energy consumption of the reactor. It is directly proportional to the filling height of the granular materials (such as adsorbent particles, catalyst particles, etc.) in the reactor, reducing the filling height of the granular materials Although the pressure drop of the reactor is reduced, the scale of the reactor is reduced. The wear of the granular material in the reactor is an important factor determining the utilization rate of the granular mate...

AI Technical Summary

Problems solved by technology

Therefore, the current gas-solid fluidized reactors (such as fluidized bed reactors, etc.) have problems such as large pressure loss and serious wear of particulate materials, which lead to low gas-solid reaction efficiency, high energy consumption, and high cost. It is urgent to develop pressure loss Gas-solid fluidized reactor with small particle material wear

[0003] At present, the research on the large pressure loss of the reactor is still in the preliminary exploration stage. Some researchers try to change the porosity of the adsorption bed in the reactor to reduce the pressure drop, but the effect is very small and affects the gas-solid reaction efficiency.

In view of the severe wear of granular materials, some researchers have tried to develop materials with high wear resistance, but these materials with high wear resistance are still in the research stage and are expensive, which cannot meet the needs of practical applications.
