Impact gas-liquid distributor

Abstract

The invention discloses an impact gas-liquid distributor, belonging to the field of petrochemical equipment. The impact gas-liquid distributor comprises jet plates, mixing plates, connectors, a hood, gas-phase cofferdams and liquid guide pipes, wherein the liquid guide pipes are connected with the connectors; the gas-phase cofferdams are sleeved outside the liquid guide pipes and gas inlet passages are formed between the gas-phase cofferdams and the liquid guide pipes; flow guiding passages are formed between the connectors and the hood; the jet plates and the mixing plates are arranged above the liquid guide pipes; a plurality of jet holes are arranged on the jet plates; a plurality of jet flow holes are arranged on the mixing plates; and a plurality of gas inlets are arranged on the walls of the liquid guide pipes between the jet plates and the mixing plates. The gas-liquid distributor has simple structure, small volume, low pressure drop and high mass transfer efficiency, is especially suitable for realizing gas-liquid distribution with gas-solid-liquid phases in fluidized state in a fluidized bed reactor and can be widely applied to the fields of petrochemical industry and environmental protection.

Description

technical field [0001] The invention relates to an impact gas-liquid distributor, which is used for gas-liquid two-phase mixing and the working condition that the gas-liquid two-phase is dispersed in a bed with the liquid phase as the continuous phase. It belongs to the field of petrochemical equipment and is suitable for Gas and liquid distribution in the reactor bed, especially a gas-liquid distribution used to realize the gas-solid-liquid three-phase boiling state in the ebullated bed reactor. Can be widely used in petrochemical and environmental protection and other fields. Background technique [0002] At present, gas-solid-liquid three-phase reactors mostly use bubble reactors and stirred tank reactors. The above-mentioned reactors have low efficiency and high energy consumption, and their application scale and application fields are limited by the reaction system. [0003] The fluidized bed process technology is widely used in petrochemical and environmental protecti...

AI Technical Summary

Problems solved by technology

The distributor has the disadvantages of complex structure, liquid phase backflow when the gas volume fluctuates, only gas phase is distributed, large bubbles are generated, and mass transfer efficiency is low.

Chinese patent CN2425703Y introduces an internal device of an ebullated bed reactor. The internal member is composed of a vertical beam and a double-layer inverted V-shaped piece. Air bubbles are formed on the double-layer inverted V-shaped piece. The distributor has a complex structure, Disadvantages such as only distributing the gas phase, large bubbles, uneven bubbles, and low mass transfer efficiency

In some reactors, most of the commonly used gas distributors use Johnson nets to generate bubbles, which have the disadvantages of only distributing the gas phase, large bubbles, and low mass transfer efficiency.
