Inverted inclined installation method and device for long-period continuous stable operation of liquid-solid micro cyclone separator

Abstract

The invention relates to an inverted inclined installation method and device for long-period continuous stable operation of a liquid-solid micro cyclone separator, and provides the inverted inclined installation method for long-period continuous stable operation of the liquid-solid micro cyclone separator. The method comprises the following steps: liquid-solid micro cyclone core tubes (4) are mounted in a feeding cavity (2) of a three-layer pressure vessel in an inverted and inclined manner, wherein the bottom flow port of each liquid-solid micro cyclone core tube (4) is connected into the bottom flow cavity (1) of the vessel, and the overflow port of each liquid-solid micro cyclone core tube (4) is connected into the overflow cavity (3) of the vessel; the scale height of the bottom flow port of each liquid-solid micro cyclone core tube (4) is higher than the scale height of the overflow port; an sharp included angle beta of the axis of each liquid-solid micro cyclone core tube (4) and the horizontal plane is larger than an accumulation angle of repose of particle materials. The invention also provides the inverted inclined installation device for long-period stable operation of the liquid-solid micro cyclone separator.

Description

technical field [0001] The invention belongs to the field of waste water treatment, and relates to an installation method for maintaining a long-period continuous and stable operation of a micro-cyclone separator used for removing fine particles in waste water. Specifically, the invention relates to an upside-down and oblique installation method and device for installing a liquid-solid micro-swirl core tube in a container. Background technique [0002] In reaction quenching systems such as methanol to olefins (MTO), petroleum catalytic cracking, isobutane dehydrogenation to isobutene, propane dehydrogenation to propylene, ethane dehydrogenation to ethylene, CLAUS furnace tail gas treatment, etc., there are a large number of circulating quenching water Fine solid particles (coke powder, catalyst, etc.) need to be removed, and the liquid-solid micro cyclone separator is widely used in the purification of suspensions in petroleum refining and chemical production processes due t...

AI Technical Summary

Problems solved by technology

[0014] The invention provides a novel upside-down tilting installation method and device for long-term continuous and stable operation of a liquid-solid micro-cyclone separator, which can effectively prevent extreme working conditions such as suspended matter deposition, operating pressure fluctuations, and especially device start-up and shutdown. The problem caused by the blockage of the bottom outlet of the liquid-solid micro-swirl core tube, thus improving the adaptability of the liquid-solid micro-swirl separator to the fluctuation of material flow exceeding the limit and the extreme working conditions of starting and stopping in actual operation, and extending the improved its stable running time, thereby solving the problems existing in the prior art
