Horizontal gas-solid reactor

Abstract

The invention discloses a horizontal gas-solid reactor which mainly comprises a horizontal reactor barrel and a stirring device. The stirring device is arranged inside the horizontal reactor barrel, a heating sleeve and a heat-insulation layer are arranged at the bottom and the top of the horizontal reactor barrel, the stirring device comprises a stirring motor, a stirring shaft, barriers and lifting plates, the stirring motor is arranged on the outer side of the reactor barrel, the stirring shaft which penetrates the reactor barrel can be driven by the stirring motor to rotate, the barriers are uniformly arranged on the stirring shaft at intervals, each lifting plate is fixedly connected with the front end of the corresponding barrier, the directions of the lifting plates on the adjacent barriers are opposite to one another, 180-degree angles are formed in the directions of the lifting plates on the adjacent barriers, and each barrier is connected with the corresponding lifting plate on the barrier in a cross manner at 90-degree angles. The horizontal gas-solid reactor has the advantages that the horizontal gas-solid reactor is insensitive to the particle size distribution of solid particles, is free of requirements on the flow rates of raw gas, is good in controllability in reaction procedures and is high in operational stability and safety and low in energy consumption, excellent reaction effects can be realized, and the reaction efficiency can be improved.

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. 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...

[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
