Description

technical field [0001] The invention relates to a reactor for chemical reaction between gas and solid, in particular to a horizontal gas-solid reactor, which belongs to the technical field of chemical equipment. Background technique [0002] At present, it is known that in chemical production, most of the gas-solid phase reactions use fluidized bed, fixed bed and other types of reactors. [0003] Among them, the fixed bed reactor is mainly used in the gas-solid phase catalytic reaction process, with simple structure, small volume, stable operation, easy control, and easy realization of large-scale and continuous production, but the bed temperature is not easy to control, and it is easy to "overheat" , and there are requirements on the size of the solid particles.

[0003] Among them, the fixed bed reactor is mainly used in the gas-solid phase catalytic reaction process, with simple structure, small volume, stable operation, easy control, and easy realization of large-scale and continuous production, but the bed temperature is not easy to control, and it is easy to "overheat" , and there are requirements on the size of the solid particles. If the particles with a small particle size are used, the fluid resistance will increase and the operation will be difficult. If the particles with a large particle size are used, the contact area of ​​the gas-solid phase reactants will be reduced. and reaction time, leading to a decrease in reaction efficiency

[0004] The fluidized bed reactor is more common in the non-catalytic gas-solid phase reaction process. It has good heat transfer effect, easy temperature control, high mass transfer and heat transfer efficiency, and large production capacity per unit of equipment. It is suitable for the production needs of large chemical industries, but it is also There are certain requirements on the size of solid particles in the reactor. If the particles are too large, the gas flow rate will be too large, resulting in poor gas-solid contact and low reaction efficiency. If the particles are too small, a large number of particles will be taken out of the reactor by the gas. , causing pipe blockage or difficulty in recycling
