Problems solved by technology

[0003] Mass transfer equipment is a kind of equipment that promotes single-phase or multi-phase close contact. Common mass transfer equipment includes packed towers, tray towers, spray towers, fixed beds, moving beds, mixing and settling tanks, etc. However, due to the need to extend the The contact time and contact area between materials are used to increase the mass transfer rate, so the built volume is usually relatively large, and some reaction towers are even as high as tens of meters in height, which has the disadvantages of large floor area, high cost, mixing intensity and mass transfer rate. Low, security risks and other issues

Abstract

The invention relates to a single-phase or multi-phase reaction device capable of effectively improving the mixing intensity and the mass transfer rate and belongs to the technical field of chemical equipment. A shell of the single-phase or multi-phase reaction device consists of a feed end cover, a discharge end cover and a barrel and is fixed on a base; a transmission shaft penetrates through the barrel and is fixed by two bearing pedestals; an isolation ring disc divides the shell into two intervals, namely a mixing chamber and a separation chamber; the mixing chamber consists of the feed end cover, a mass transfer disc and the isolation ring disc; a feed through hole is formed in the feed end cover and is connected with the mixing chamber; the separation chamber consists of the isolation ring disc, an impeller and the discharge end cover; the mass transfer disc and the impeller are fixed on the transmission shaft and rotate along with the transmission shaft; reaction fluid enters the separation chamber and is centrifugally separated by the impeller fixed on the transmission shaft, a heavy phase is thrown to the outer ring of the shell, and a light phase is extruded to the periphery of the transmission shaft by the heavy phase; a light-phase discharge through hole is formed in a position, close to the transmission shaft, on the surface of the discharge end cover; a heavy-phase discharge through hole is formed outside the surface of the discharge end cover. The device can effectively improve the mixing intensity and the mass transfer efficiency.

Description

technical field [0001] The invention relates to a single-phase or multi-phase reaction device for effectively improving mixing intensity and mass transfer rate, and belongs to the technical field of chemical equipment. Background technique [0002] In the industrial production of chemical industry, biology, petroleum, metallurgy and other industries, the vast majority of chemical reactions involve single-phase or multi-phase mass transfer processes, such as the transfer of substances between the gas phase and the liquid phase in the distillation process, and gas absorption , aeration, gas elution and other gas-liquid reactions, that is, heterogeneous reactions; in extraction, substances are transferred between two liquid phases, that is, single-phase reactions, but during the reaction, the reaction products will inhibit the reaction or inhibit The reaction reaches equilibrium, and the efficiency of the reaction process can only be improved by ensuring a high interphase conve...
