Description
Technical field
The utility model is related to petrochemical industry and technical field of coal chemical industry, more particularly to a kind of to separate single tube and apply its
Third-stage cyclone separator.
Background technology
At present, in petrochemical industry and technical field of coal chemical industry, the corresponding energy of ash-laden gas that regenerator is produced is accounted for
The significant proportion of the gross energy produced in whole system, therefore for the utilization rate of energy in raising system, can be by using
Flue gas turbine expander is reclaimed to this portion of energy produced by regenerator.But, due to the catalyst granules meeting in ash-laden gas
Abrasion is caused to flue gas turbine expander, or even causes unplanned property to stop work, produce unnecessary economic loss；Therefore it is above-mentioned existing to avoid
The generation of elephant, generally sets up third-stage cyclone separator before flue gas turbine expander, so that the catalyst contained in ash-laden gas
The particle diameter distribution of concentration and catalyst reaches Con trolling index, so as to ensure the safety fortune that flue gas turbine expander can be steady in a long-term
OK.
Multiple separation single tubes, generally separation single tube of the prior art, bag can be installed in third-stage cyclone separator
Include reverse-flow separation single tube and single flow separates single tube.Wherein, because the bottom section of reverse-flow separation single tube is cone section structure,
And the reverse-flow air inlet pipe and blast pipe for separating single tube is respectively positioned on the top of single tube, therefore there is descending contour stealth simultaneously in it
With up inward eddy, interior contour stealth is susceptible to blending and causes " short circuit " phenomenon in running, so as to part not entered also
Row separate catalyst granules be directly involved in blast pipe, cause separative efficiency to decline, and inward eddy presence cause it is reverse-flow
The pressure loss for separating single tube is larger.Single flow separates the air inlet pipe and blast pipe of single tube respectively positioned at the top and bottom of single tube
Portion, and it is straight barrel type structure that single flow separates single tube, and inward eddy gas will not be produced inside it, and reverse-flow separation can be overcome single
Deficiency in pipe；However, existing single flow separates single tube because no inward eddy is produced, thus its flow field spin intensity compared with
Reverse-flow separation single tube is low, therefore flow rotation intensity is slightly weak, and separative efficiency is relatively low.When the intake method for separating single tube is use
During axial admission, i.e., airintake direction is consistent with the axial direction of single tube, and the catalyst granules in ash-laden gas is easily directed to leaf
Piece is smashed, and so as to cause small particle catalyst granules content to increase, also causes the separative efficiency of axial admission separation single tube obvious
Reduce.
Therefore, present inventor discovers how to provide a kind of separation single tube for third-stage cyclone separator, can
Effectively improve the separative efficiency for separating single tube, the technical problem as those skilled in the art's urgent need to resolve.

To the inwall of separable cartridge 12, and by the air-flow that is moved downward near inwall by catalyst granules along separable cartridge 12 inner wall belt
To at the bottom wall of separable cartridge 12, so that catalyst granules can be discharged by the multiple dust-exhausting ports 15 on bottom wall, and purifying smoke
Can be discharged by the blast pipe 14 of separation single tube.
In the separation single tube that the utility model embodiment is provided, baffle 13, baffle are provided with separable cartridge 12
13 setting reduces the sectional area of separable cartridge 12, increases the tangential velocity of air-flow, improves the spin intensity of air-flow, from
And improve separative efficiency；Meanwhile, baffle 13 setting cause single tube center to barrel direction radial velocity maximum to
Move in barrel direction so that particle is easier to be thrown toward barrel, so as to be more easy to by downward air-flow band to dust-exhausting port 15, is conducive to
Separative efficiency is improved, single tube separative efficiency raising more than 2% is separated without baffle single flow than common.
Additionally, the setting of baffle 13 reduces the tubulence energy in flow field, guide whole even flow field to rotate in order, improving
The stability in flow field is ensure that while efficiency so that the pressure loss remains at relatively low on the premise of spin intensity increases
Level.
