Embodiment 1

[0037] The supergravity field rotating bed mass transfer and reaction equipment of the present invention is applied to the absorption of sulfur dioxide in the tail gas of a sulfuric acid plant by using ammonium sulfite. The principle is ammonium sulfite and SO 2 After the reaction, ammonium bisulfite is generated. Ammonium bisulfite is a good reducing agent. When the ammonium bisulfite reaches a certain concentration, it leaves the system as a product. The process flow of the prior art is a two-stage method, which adopts two operating towers to complete, and the SO2 in the raw material gas of the one-stage tower is 2 The absorbing liquid is high-concentration ammonium-containing liquid, which is equivalent to the concentration tower, the raw material gas of the second-stage tower is the outlet gas of the first-stage tower, and the absorbing liquid is the lower-concentration ammonium-containing liquid, which is equivalent to the purification tower, and the outlet gas is in the ...

Abstract

The present invention discloses an ultragravitational field rotation bed mass transfer and reaction equipment. Said equipment comprises machine shell, rotor, rotary foam-catching device and transmission device. The described machine shell comprises gas inlet end cover, straight cylinder section and gas outlet end cover; the described transmission device is formed from motor, transmission shaft, supporting bearing and seal system, and the described rotor is formed from dual rotors, and is consisted of two metal frames with shared bottom plate, two phases of gas and liquid can be parallelly-flowed and contacted on one rotor, and on another rotor they are counter-current-wise contacted, and the rotors are fixed on the shaft by means of shared bottom plate. Said invented equipment can be extensively used in the mass transfer and reaction process of multiphase material system of gas-liquid, gas-liquid-solid and gas-liquid-liquid.

Description

technical field [0001] The invention relates to a rotating bed mass transfer and reaction equipment which is formed by the centrifugal force of a rotating packed bed (hereinafter referred to as a rotating bed) to form a supergravity field to strengthen the mass transfer and reaction process. Background technique [0002] The supergravity field rotating bed mass transfer and reaction equipment is a new type of equipment developed in the early 1980s. Compared with the conventional technology, the equipment has the following characteristics: high mass transfer intensity, small equipment size, short material residence time, small liquid holding capacity, high flooding point, not easy to foam, not easy to block, easy to maintain, and can be used in a few minutes. Make the equipment run stably. [0003] Usually the supergravity field rotating bed equipment consists of a casing, a rotor, a material inlet and outlet, a rotating shaft and a motor. The rotor is filled with a porous ...
