Super-gravity revolving bed provided with multi-layer cylindrical rotary liquid distributor

Abstract

The invention relates to a super-gravity revolving bed provided with a multi-layer cylindrical rotary liquid distributor. The revolving bed comprises a shell, a rotating shaft, a rotor and the multi-layer cylindrical rotary liquid distributor, wherein the multi-layer cylindrical rotary liquid distributor comprises a feed chute and a plurality of layers of cylinders; the middle of the multi-layer cylindrical rotary liquid distributor is provided with a cylindrical hollow feed chute which is communicated with a liquid inlet; the outer side face of the feed chute is provided with cylinders which are coaxially arranged at certain radial intervals and embedded layer upon layer; the inner wall of the feed chute and the inner wall of each layer of cylinder are provided with liquid outlet holes of which the number increases layer by layer; a liquid passage is formed by communicating the cylinders through the liquid outlet holes; and the liquid outlet hole on an outermost layer of cylinders corresponds to the inner edge of a rotor. The revolving bed has the advantages that: 1, liquid is initially and uniformly distributed well in a circumferential direction and an axial direction under the action of centrifugal force; 2, the revolving bed achieves higher mass transfer efficiency; and 3, the structure is more simple, compact and reasonable and equipment is easy to manufacture and install.

Description

Technical field [0001] The invention relates to the field of supergravity rotating beds, in particular to a supergravity rotating bed with a multilayer cylindrical rotating liquid distributor. Background technique [0002] The supergravity field technology is a breakthrough technology to enhance the transfer and multiphase reaction process. Utilizing the highly enhanced mass transfer process and micro-mixing process characteristics in the supergravity environment, the chemical tower equipment up to tens of meters can be replaced with a supergravity machine less than two meters in height, so the supergravity rotating bed is known as the chemical equipment The "transistor". The existing rotating bed mostly adopts a fixed liquid distribution method, that is: connect the liquid distributor with the casing or other fixed supports, the liquid inlet pipe is stationary, and the liquid is sprayed through the liquid distributor pipe on the liquid distributor by the pressure of the pump T...

AI Technical Summary

Problems solved by technology

The liquid is distributed by the centrifugal force generated by the rotation, which improves the operating range of the liquid flow, but this type of liquid distributor needs a dynamic sealing structure between the liquid feed pipe, the structure of the distributor is complicated, and the production and installation are troublesome; the liquid is axially distributed in the liquid distribution pipe. uneven distribution

[0004] Chinese patents CN 101254356A and CN101254357A disclose the concentric ring counterflow type supergravity rotating bed device, which has the advantages of high mass transfer efficiency, easy realization of intermediate feeding, and convenient multi-layer installation. However, this type of rotating bed requires relatively high initial distribution of liquid. High, whether the liquid distribution is uniform or not directly affects the mass transfer performance of the equipment

The layer-by-layer partition distributor and stepped distributor used in this type of device can achieve the initial distribution of the liquid, but the liquid is not evenly distributed in the axial direction of the moving disk, and the void ratio of the distributor is low, which is easy to flow in the tower. It forms the bottleneck of the gas channel, and the manufacture and installation of the distributor is troublesome
