Abstract

The utility model relates to a combined gas-solid separator for treating high concentration. According to the technical scheme, an inlet pipe is connected to the lateral wall of the upper part of a cylinder body, a conical ash hopper is arranged at the bottom of the cylinder body, and an exhaust pipe is connected to the top part of the cylinder body; a gas-solid separation device is arranged in the inner cavity of the cylinder body and comprises a first-stage guide vane, a side seam, a second-stage guide vane, a diversion core pipe, an anti-re-entrainment cone and a separation tube wall, wherein the first-stage guide vane is arranged on the upper part of the separation tube wall, and a plurality of side seams are formed in the tube wall of the lower part of the first-stage guide vane; the second-stage guide vane is arranged on the lower part of the side seams; the anti-re-entrainment cone is arranged at the lowest end of the separation tube wall; an exhaust pipe is arranged at the center of the separation tube wall. The combined gas-solid separator has the beneficial effects that the gas-solid separation efficiency can be improved by adopting the two-stage separation mode, but pressure drop of the equipment is hardly increased, the direct-current and countercurrent inversion modes are effectively combined, the advantages of each separation mode are sufficiently utilized, and the problem of separating high solid concentration can be solved.

Description

A kind of combined gas solid separator of processing higher concentration

Technical field

The utility model relates to a kind of device of gas solid separation of petrochemical industry, particularly a kind of combined gas solid separator of processing higher concentration.

Background technology

At present, equipment about gas solid separation is a lot, but for the gas solid separation research that contains higher concentration and few, and this operating mode is more common, such as catalytic cracking fourth stage separator is exactly for this operating mode, at the scene in application, adopt cut flow-type separator more, there is certain effect, but higher owing to entering to suck catalyst concn, the effect of this single-stage separator is still difficult to reach requirement, the on-the-spot circumstances that often occurs critical spray nozzle wearing and tearing, and too much solid catalyst is discharged in atmosphere, contaminated environment, therefore, be necessary very much separator herein to be improved.

Summary of the invention

The purpose of this utility model is exactly in view of the foregoing defects the prior art has, and a kind of combined gas solid separator of processing higher concentration is provided, and its principle based on centrifugation is utilized direct current separation to reverse to separate with adverse current and combined.

Its technical scheme is: comprise that separator is by inlet tube, blast pipe, gas-solid separating device, cylindrical shell, ash bucket, in described cylindrical shell upper portion side wall, connect inlet tube, bottom is the ash bucket of taper, top connects blast pipe, described cylinder lumen is provided with gas-solid separating device, gas-solid separating device comprises first order guide vane, latasuture, second level guide vane, shunting core pipe, anti-back-mixing is bored and is separated tube wall, the top that separates tube wall is provided with first order guide vane, the tube wall of the bottom of first order guide vane is provided with many latasutures, second level guide vane is installed in the bottom of latasuture, what separate tube wall is anti-back-mixing cone bottom, the center of described separation tube wall is provided with blast pipe.

Above-mentioned blast pipe outer end connects gas fairlead, and the bottom of blast pipe is shunting core pipe.

The beneficial effects of the utility model are: the mode that adopts two-stage to separate, improve gas solid separation efficiency, the pressure drop that does not simultaneously cause equipment increases how many, effectively direct current and adverse current inversion mode are combined, make full use of the advantage of every kind of separate mode, reach the separation problem that solves higher solids concentrations, be applicable to process the gas solid separation of higher concentration.

In upper figure: inlet tube 1, blast pipe 2, first order guide vane 3, latasuture 4, second level guide vane 5, shunting core pipe 6, anti-back-mixing cone 7, cylindrical shell 8, ash bucket 9, gas fairlead 10, separation tube wall 11.

Detailed description of the invention

1-4 by reference to the accompanying drawings, the utility model will be further described:

The utility model comprises that separator is by inlet tube 1, blast pipe 2, gas-solid separating device, cylindrical shell 8, ash bucket 9, in described cylindrical shell 8 upper portion side wall, connect inlet tube 1, bottom is the ash bucket 9 of taper, top connects blast pipe 2, described cylindrical shell 8 inner chambers are provided with gas-solid separating device, gas-solid separating device comprises first order guide vane 3, latasuture 4, second level guide vane 5, shunting core pipe 6, anti-back-mixing cone 7 with separate tube wall 11, the top that separates tube wall 11 is provided with first order guide vane 3, the tube wall of the bottom of first order guide vane 3 is provided with many latasutures 4, second level guide vane 5 is installed in the bottom of latasuture 4, what separate tube wall 11 is anti-back-mixing cone 7 bottom, described separation tube wall 11 center is provided with blast pipe 2.

Above-mentioned blast pipe 2 outer ends connect gas fairlead 10, and the bottom of blast pipe 2 is shunting core pipe 6.

When use, gas-solid mixture enters from separator inlet 1, enters first order guide vane 3 and makes and revolve, due to the effect of centrifugal force, solid particle is thrown to limit wall, during through the latasuture 4 of tube wall, discharge from latasuture, then flow into rewinding tank along wall downwards by gravity, be also attended by a small amount of gas simultaneously and discharge, the increase of gas causes the rising of cavity inside pressure, in the time that pressure reach a certain height, gas can enter in blast pipe by gas fairlead 10, and pressure keeps constant afterwards; Now in separator tube, solid concentration declines, and then enters second level guide vane 5 and further makes and revolve, under the effect of centrifugal force, solid is thrown to wall, enters ash bucket by gravity current, and separator center pressure is low, gas, to center flow, is then discharged from blast pipe 2.Finally, contained solid is all collected in ash bucket, discharges from discharge gate, and clean gas is discharged from blast pipe, has realized the gas solid separation of higher concentration.The existence of shunting core pipe 6, has improved separating effect, has reduced short-circuit flow; Anti-back-mixing cone 7 prevent the separated particle getting off again back-mixing enter in separator.In addition, the direction of cracking of first order guide vane, second level guide vane, tube wall latasuture and shunting core pipe is identical, is beneficial to separation.
