Description
Technical field
The present invention relates to incineration treatment of garbage field, more particularly to a kind of circulating fluid bed garbage furnace drum-type feed
Device and feeding method.
Background technology
The charging gear of initial circulating fluid bed garbage furnace is negative pressure feeding method, that is, control furnace pressure or carry
High material inlet absolute altitude so that it is negative pressure region that rubbish enters the region of burner hearth, to avoid burner hearth high-temperature flue gas anti-channeling to feed dress
Fire is produced in putting and is leaked and is polluted environment.There is the single-stage feeding manner fed by one-level feed screw and lead to
Cross the versions such as the two-stage feeding manner that deuterostrophies charger is fed.China Patent No. be 2007201819504,
Authorized announcement date is August 20, a kind of patent of entitled " two-stage screw biomass solid particle conveying device " text in 2008
A kind of feed arrangement of two-stage feeding manner is disclosed in offering.Above feed arrangement has the following disadvantages：Can because feed fluctuation or
Furnace pressure fluctuates and flue gas anti-channeling phenomenon occurs；Rubbish is thrown into the position of burner hearth rubbish can be changed in company with the velocity of rotation of batcher
Become, cause rubbish to be stably delivered to the central area of burner hearth, affect adequacy and efficiency when burning, exacerbate stove
The fluctuation of gun pressure power.In order to overcome the above-mentioned deficiency of existing feed arrangement, it is 2012205908688, authorizes in China Patent No.
The day for announcing is to disclose one in July, 2013 No. 3, the patent document of entitled " circulating fluid bed garbage furnace charging gear "
Plant by expecting envelope to be sealed against only expecting that fluctuation or furnace pressure fluctuate and generation flue gas anti-channeling phenomenon.Existing two is grading
Although material device solves flue gas anti-channeling phenomenon, but during spiral feeds, the packing of rubbish can be with charging distance
Increase and increase, hence in so that can produce hardened phenomenon into the rubbish in incinerator and so that can not fully burn, fire
Burn it is insufficient, the substantial amounts of dense smoke rich in carbon monoxide can be produced, the generation of dense smoke can cause vent gas treatment cost increase.
The content of the invention
The invention provides a kind of packing of rubbish with charging distance increase and incrementss it is little cause garbage energy
Enough circulating fluid bed garbage furnace drum-type charging gears and feeding method that incinerator is entered with loose condition (of surface), solve existing
Hardened phenomenon is produced during some charging gear feedings and causes insufficient, vent gas treatment high cost the problem of burning.
Above technical problem is solved by following technical proposal：A kind of circulating fluid bed garbage furnace drum-type is given
Material device, including one-level batcher and two grades of batchers, the one-level batcher is located at two grades of batcher tops, and the one-level is given
Material machine discharging opening and two grades of batcher imports are docking together by dipleg, and two grades of batchers include back-up roller wheel, send
The drive mechanism that feed roller and driving feeding roller are rotated, the feeding roller is supported on the support in the way of circumferential contact
On roller, the feed end of the feeding roller links together with the dipleg rotary seal, is provided with the feeding roller
Some spiral stators, the radial outer end of the spiral stator is fixed together with the inner peripheral surface of the feeding roller, the spiral shell
The radial inner end of rotation stator is surrounded into material space.When using, the port of export of feeding roller is set to be docked at the charging aperture of incinerator
Together, rubbish forms material envelope Jing after one-level batcher enters dipleg in dipleg, and then bis- grades of batchers of Jing are sent to burning
Burnt in stove.The version of two grades of batchers, the power of the conveying garbage that spiral stator is produced is to draw to discharge end
（And the power that traditional screw(-type) feeder is produced is that phase discharge end is pushed away）Therefore it is crowded to drive rubbish that rubbish is not easily leaded to when moving forward
Pressure and lump so that into incinerator rubbish loosely, rubbish during burner hearth loosely then into full and uniform can scattering so that
Burning is abundant, and the flue gas that burning is fully then produced is few, flue gas fume treatment low cost at least.The rolling of feeding roller can pass through
Or the actuating units such as motor are directly driven drives support wheel to roll by actuating unit, support wheel goes to drive feeding again
Cylinder is rolled.
Preferably, some pressure release that the spiral stator is provided with the circumferential insertion spiral stator along feeding roller lacks
Mouthful, the spiral stator is divided into some stator fragments by the pressure release breach.Can further prevent in fill process
Produce rubbish caking phenomenon.
Preferably, the pressure release breach is " V " font.Releasing effect is good, can more effectively prevent rubbish
Produce caking phenomenon.
Preferably, between two stator fragments adjacent in the stator fragment on same head spiral stator, one
For it is fan-shaped, another be abnormity.The direction for enabling to the hardened power of extruding suffered when rubbish moves ahead produces change, so as to
Play a part of to prevent rubbish from producing caking phenomenon.
Preferably, the spiral stator at least two, the pressure release breach edge on adjacent spiral stator
The circumference of feeding roller staggers.It is prevented from rubbish residual to be produced in feeding roller and causes to feed resistance increase, charging resistance
Power does not increase, and patency during charging is good and does not allow to be also easy to produce hardened phenomenon.
Preferably, the spiral stator is gradient pitch structure, the pitch of the spiral stator is from the feeding roller
Feed end become larger to discharge end.The effect for preventing rubbish from producing hardened phenomenon can be improved.
Present invention additionally comprises preventing the feeding roller from producing the thrust wheel of axial float.It is prevented from feeding roller generation
Axial float such that it is able to enable feeding roller to keep reliable sealing with the equipment being connected for a long time.
Preferably, the outside face of the feeding roller is provided with the prominent week along feeding roller with feeding roller outer surface
To the ring raceway for extending, the back-up roller wheel is supported in the raceway, and the thrust wheel has a pair, states in thrust wheel for a pair
Two thrust wheels are distributed in the axial two ends of the raceway.It is easy to make.Cost of manufacture can be reduced.
Preferably, the discharge end of the feeding roller is to being connected to incinerator, the incinerator is provided with exhanst gas outlet, described
The port of export of dipleg is provided with airduct import, and the airduct import is docking together with conveying exhanst gas outlet.Cigarette can either be caused
Gas be back in incinerator again burnt again, to reduce fume treatment cost；The heat of flue gas can also be utilized simultaneously
It is dried to flowing through two grades of batcher rubbish, reduces the moisture into stove rubbish, realizes the recycling of tail gas heat quantity.
A kind of circulating fluid bed garbage furnace feeding method, by make the feeding speed of one-level batcher more than two grades to
The mode of the feeding speed of material machine forms material envelope in dipleg；Material envelope formed after by make one-level batcher feeding speed and
The feeding speed matching of two grades of batchers and keep the presence of material envelope, two grades of batchers are by with feeding roller rotation and spiral is led
The mode that leaf is connected on feeding roller is fed, by by spiral stator be set to pitch from the feed end of feeding roller to
Gradient pitch structure that discharge end becomes larger, preventing the rubbish caking entered in incinerator.
Present invention tool has the advantage that：Rubbish into incinerator is not allowed to be also easy to produce caking phenomenon, can be entered by rubbish
The uniformity of material so that more abundant during incineration firing so that the exhaust gas volumn produced during incineration firing is few.
