Description
Technical field
The present invention relates to the water coal pulp fluidized bed boiler structure of a kind of multiple stage separation.
Background technology
Water coal pulp fluidized bed boiler has simple in construction, efficiency of combustion advantages of higher, but in the structure of existing design, boiler
Possibly together with combustible bed and water-coal-slurry granule in expellant gas, it is expelled directly out causing energy waste, causes burning effect
Rate is low.
Summary of the invention
For the problems referred to above, the present invention provides the water coal pulp fluidized bed boiler structure of a kind of multiple stage separation, makes full use of energy
Source, improves efficiency of combustion.
For realizing above-mentioned technical purpose, reaching above-mentioned technique effect, the present invention is achieved through the following technical solutions:
The water coal pulp fluidized bed boiler structure of a kind of multiple stage separation, including slurry can and oil storage tank, described slurry can and oil storage tank
Being connected with CFBB, described CFBB is sequentially connected with cleaner unit, air-introduced machine and chimney, described storage slurry
Slurry supply pump and pelletizer it has been sequentially arranged, between described oil storage tank and CFBB between tank and CFBB
Oil feed pump, oil gun and heat smoke generator are sequentially arranged it, it is characterised in that between described CFBB and cleaner unit
It is sequentially arranged primary cyclone and secondary cyclone, bottom described primary cyclone, is provided with primary feedback
Passage, is provided with the secondary passage that feeds back, the described primary other end feeding back passage and circulation bottom described secondary cyclone
Fluidized-bed combustion boiler is connected, and the described secondary other end feeding back passage is connected with collecting box.
Preferably, described collecting box inwall is provided with cooling water pipeline.
Preferably, described collecting box is cylindrical shape.
Preferably, described cooling water pipeline is arranged on inwall to bottom spiral from the top of collecting box.
The invention has the beneficial effects as follows: the bed carried with heat smoke and water-coal-slurry cluster of grains by primary cyclone and
Secondary cyclone separation deposition is got off, and wherein, bigger bed material in primary cyclone and water-coal-slurry cluster of grains are through just
Level feeds back in passage is back to CFBB burns, and improves efficiency of combustion, reduces and pollute.And secondary cyclone separates
Less bed and water-coal-slurry cluster of grains in device then feed back passage to be back to collecting box deposit be its use through secondary, do not enter back into and follow
In circulation fluidized bed boiler, fully utilize according to the characteristic of the energy, to reach optimal utilization more.

Detailed description of the invention
With specific embodiment, technical solution of the present invention is described in further detail below in conjunction with the accompanying drawings, so that ability
The technical staff in territory can be better understood from the present invention and can be practiced, but illustrated embodiment is not as the limit to the present invention
Fixed.
As it is shown in figure 1, the water coal pulp fluidized bed boiler structure of a kind of multiple stage separation, including slurry can 1 and oil storage tank 2, institute
State slurry can 1 to be connected with CFBB 8 with oil storage tank 2, described CFBB 8 sequentially with cleaner unit 12, draw
Blower fan 14 is connected with chimney 15, has been sequentially arranged slurry supply pump 3 and pelletizer between described slurry can 1 and CFBB 8
5, it is sequentially arranged oil feed pump 4, oil gun 6 and heat smoke generator 7 between described oil storage tank 2 and CFBB 8.
Primary cyclone 10 and secondary cyclone have been sequentially arranged it between described CFBB 8 and cleaner unit 12
Separator 11, is provided with primary feedback passage 16, described secondary cyclone 11 end bottom described primary cyclone 10
Portion is provided with the secondary passage 17 that feeds back, and the described primary other end feeding back passage 16 is connected with CFBB 8, described time
Level feeds back the other end of passage 17 and is connected with collecting box 18.
The bed carried with heat smoke is separated with secondary cyclone by primary cyclone with water-coal-slurry cluster of grains
Deposition is got off, and wherein, bigger bed material and water-coal-slurry cluster of grains in primary cyclone feed back passage through primary and be back to follow
Burn in circulation fluidized bed boiler, improve efficiency of combustion, reduce and pollute.And the less bed in secondary cyclone and water
Coal slurry cluster of grains then feed back passage to be back to collecting box deposit be its use through secondary, does not enter back in CFBB, fills
Point utilize according to the characteristic of the energy, to reach optimal utilization more.
Owing to the less bed in secondary cyclone and water-coal-slurry cluster of grains possess certain heat, therefore can receive
Header 18 inwall is provided with cooling water pipeline, and such as, described collecting box 18 is in cylindrical shape, and described cooling water pipeline is from collecting box
