Dense phase transport bed reactor

Abstract

A dense phase transport bed reactor belongs to the technical field of chemical industrial gas-solid two phase reaction equipment. The dense phase transport bed reactor comprises a top feeding port, gas transport passages, transport beds, a separator, a solid collector and a gas collector, wherein the transport beds contain multiple levels, and each level of transport bed, which slants down, is composed of a transport groove, an air distribution plate disposed on the lower portion of the transport groove and an air compartment; two adjacent level of transport beds are connected end to end by a horizontal transition section; the gas transport passages lead out a plurality of gas branches, and the air compartment of each level transport bed is connected with the gas transport passages by the gas branches. According to the dense phase transport bed reactor, the transport beds are utilized to carry out the gas-solid two phase reaction. The transport process is stable, the concentration of a solid reactant is high, and the reaction speed of a mixture can be regulated by adjusting the inclination angle. The dense phase transport bed reactor has advantages of high concentration of the reaction solid, stable reaction process, easily controllable reaction time, simple structure and the like, and especially is suitable for the gas-solid two phase reaction with high concentration of the solid reactant.

Description

technical field [0001] The invention relates to a dense-phase transport bed reactor, which belongs to the technical field of chemical gas-solid two-phase reaction equipment. Background technique [0002] Gas-solid two-phase reaction is the most widely used and largest scale reaction process in the chemical industry. In current chemical production, gas-solid phase reactions are usually carried out in fixed-bed reactors, moving-bed reactors or fluidized-bed reactors. These three reactors have some disadvantages: fixed bed reactors cannot realize continuous input and output of solid materials; although moving bed reactors and fluidized bed reactors can realize continuous input and output of materials, the input of materials The concentration and output concentration must be controlled within a certain range, and the reaction time is generally difficult to adjust. For some gas-solid two-phase reactions that require a high concentration of input solid reactants, fixed-bed react...

These three reactors have some disadvantages: fixed bed reactors cannot realize continuous input and output of solid materials; although moving bed reactors and fluidized bed reactors can realize continuous input and output of materials, the input of materials The concentration and output concentration must be controlled within a certain range, and the reaction time is generally difficult to adjust

For some gas-solid two-phase reactions that require a high concentration of input solid reactants, fixed bed reactors cannot be used, and when moving bed or fluidized bed reactors are used, the reaction efficiency will be relatively low
