Abstract

The invention particularly relates to a composite baffling revolving bed mass transfer and reaction device. The device comprises a static disk, a fluid distributor, a fluid inlet pipe, a gas outlet pipe, an upper guide flow plate, a lower guide flow plate, a gas inlet pipe, a moving disk, a rotating shaft, a fluid outlet pipe and a shell body; the static disk and the moving disk are placed in the shell body, and several concentric ring shaped guide flow plates with different diameters are arranged on the static disk; evenly distributed circular small holes are arranged on the upper guide flow plate, and several concentric circular cone shaped lower guide flow plates are arranged on the moving disk; evenly distributed puncture holes are arranged on the lower guide flow plate; the upper guide flow plate and the lower guide flow plate are aligned in a staggering manner; the static disk is fixedly connected with a gas outlet pipe, the moving disk is fixedly connected with the rotating shaft; one end of the rotating shaft crosses through the shell body and seals with the shell body. Through changing the flow path of the gas fluid flow body, the uniform gas fluid distribution is improved by fully using the inside diameter direction of a rotor and an axial space, the gas and fluid contact time is effectively prolonged; through adding the gas disturbance degree, the gas phase mass transfer efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of mass transfer and reaction in a supergravity field, in particular to a composite baffled rotating bed mass transfer and reaction equipment. Background technique [0002] Hypergravity technology is one of the typical chemical process intensification technologies, which greatly strengthens the gas-liquid mass transfer, heat transfer and reaction process. In the high-gravity rotating bed, the liquid is sheared and broken by the high-speed rotating packing to form liquid droplets, liquid filaments, and liquid films with extremely large surfaces and constantly renewed. The contact with the gas passing through the packing strengthens the microscopic mixing of gas and liquid, making the transfer The quality coefficient has been increased by 1 to 2 orders of magnitude, and it has the advantages of high liquid flooding and short residence time of materials. After years of development, the high-gravity rotating be...
