Mass transfer and reaction equipment for reverse airflow shearing and rotating packed bed

Abstract

The invention belongs to the technical field of mass transfer reaction equipment, and particularly relates to mass transfer and reaction equipment for a reverse airflow shearing and rotating packed bed which solves the problems of the existing ultragravity equipment in the aspect of air phase mass transfer. The mass transfer and reaction equipment comprises a rotating bed main body, an equipment bracket and a transmission device, wherein the rotating bed main body comprises an upper part and a lower part which are an air collection chamber and a main cavity; the main cavity is internally provided with a packing rotor capable of rotating at a high speed; the upper part of the main cavity is connected with an air inlet pipe; the bottom of the main cavity is connected with a drainage pipe; the center of the packing rotor is provided with a liquid distributor; the liquid distributor is connected with a liquid inlet pipe; the top of the air collection chamber is connected with an exhaust pipe; an opening in the top of the packing rotor is communicated with the air collection chamber. The mass transfer and reaction equipment has the beneficial effects that the shearing stress for fluid can be increased, more momentum is transferred to interior fluid by packing, the boundary layer separation of air liquid is promoted, the degree of turbulence is increased, and the update rate of air liquid interface is increased, and thus the purpose of strengthening the air phase mass transfer is achieved; the operation stability is improved, and the equipment is suitable for high throughput occasions; the air collection chamber effectively inhibits the influences on operation balance caused by entrainment and flooding.

Description

technical field [0001] The invention belongs to the technical field of chemical industry, petrochemical industry, and environmental protection mass transfer reaction equipment, and specifically relates to a mass transfer and reaction equipment of air flow reverse shearing rotating packed bed, which can be used for intensifying the mass transfer process of gas film control such as rectification and absorption . Background technique [0002] Hypergravity technology is a breakthrough technology developed in the 1980s to strengthen the multiphase transfer and reaction process. In the gravity environment, the liquid is sheared and atomized by the filler, the contact area between the phases increases, and the rapid renewal of the surface leads to the great enhancement of the mass transfer, heat transfer and reaction process controlled by the liquid phase. At present, it is mainly used in desulfurization, decarburization, dust removal and nano-material preparation. [0003] At pr...
