High-pressure rotary bed gas-liquid mass-transferring and reaction equipment in superheavy force field

Abstract

The present invention relates to a gas-liquid mass transfer and reaction equiopment of high-pressure rotating bed in ultragravity force field. Said invention drive equipment is a magnetic drive equipment, including driving portion, driving magnetic stell protecting cover positioned on the exterior of the machine shell and driving magnetic steel and driving shaft which are placed in the protecting cover and driven portion, driven magnetic steel protecting cover positioned in the interior of the machine shell and driven magnetic steel and driven shaft which are placed in the driven magnetic steel protecting cover. The driving portion and driven portion are separatedy by means of magnetic isolation cover between both them. Said invention adopts band pressure design and measures of internal and internal magnetic steel protecting cover, magnetic steel cooling system, high-effective coating layer and others so as to raise mass transfer effect.

Description

technical field [0001] The invention relates to a rotating bed mass transfer and reaction equipment which forms a supergravity field by the centrifugal force of a rotating packed bed (hereinafter referred to as the rotating bed) to strengthen the mass transfer and reaction process. Especially for mass transfer and reaction process of medium, high pressure, flammable, explosive and corrosive gas-liquid, liquid-liquid, gas-liquid-solid multiphase systems. Background technique [0002] The high-gravity 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 rotating bed mass transfer and reaction equipment has the following characteristics: its mass transfer intensity is high, the equipment size is small, the residence time is short, the liquid holding capacity is small, the flooding point is high, it is not easy to foam, it is not easy to block, and it is easy to maintain. ...

AI Technical Summary

Problems solved by technology

[0005] Chinese patent documents CN 91109255, CN 91111283, CN 912292040, CN 9210000936 and CN 952154307 etc. all disclose some relevant rotating bed mass transfer and reaction equipment, but the structures disclosed in these patent documents can only be used in normal pressure process, and have leakage problems

[0006] In addition, although the Chinese patent document CN 992006961 discloses a device that uses magnetic power to solve the sealing problem, it can only be used in normal pressure processes from the perspective of its device structure

And its magnetodynamic structure also has gaps

For example: it does not solve the problem of discharging the magnetic eddy current heat, and if the magnetic eddy current heat cannot be discharged, the long-term operation of the equipment is easy to cause demagnetization; meanwhile, the magnetic power of the rotating bed mass transfer and reaction equipment disclosed in CN 992006961 is also Only suitable for low power processes
