Description
Technical field
The present invention relates to a kind of cooling and warming unit, be specifically related to a kind of coal dust firing and produce the burning of steam and water coke slurry
Unit.
Background technology
The operation principle of existing cooling and warming unit is: coal dust firing produces thermal source and is directly sprayed onto in boiler body, then
Swapping, this method of operation there is problems in that
, combustion heat loss big: boiler is to burn natural gas or oil, and heat-exchange system needs boiler to conduct, in coal-burning boiler,
Can there is solid imperfect combustion phenomenon, even if fuel burns completely, big portion all can be inevitably taken away in its deslagging and smoke evacuation
Divide heat.
, exhaust gas temperature the highest, reach 160 DEG C (GB is less than 110 DEG C), the most energy-conservation.
(3), smoke evacuation composition: the pollutant in Pulverized Coal Combustion Products are mainly dust, SO2And nitrogen oxides, owing to coal dust is complete
Full burning, its fly ash granule diameter is all below 10 μm, and common filtration method for separating polluted particles not only can not effectively remove impurity, and
And it cannot be guaranteed that outflow, current large-scale processing equipment cost is high, equipment is big, in-convenience in use.
(4), heat-transfer surface consumptive material: owing to existing boiler all uses indirect heat exchange (lowering the temperature with water-cooling wall), need a large amount of steel pipe to make
For heat-transfer surface, and life-time service there will be surface texture and internal blocking etc., ultimately causes heat exchange incomplete, wastes the energy.
Summary of the invention
The present invention solves that existing cooling and warming unit exists when running that heat loss is higher, discharge fume into distribution environmental protection, heat exchange
The problem that face consumptive material is big, and then the burning unit of a kind of coal dust firing generation steam and water coke slurry is proposed.
A kind of coal dust firing of the present invention produces the burning unit of steam and water coke slurry and includes burner, spraying mechanism, cigarette
Gas radiating tube, centrifugal slag remover, flue gas condensing heat exchange coil, connect heat pump heat exchanging coil pipe, turbulence blades, water tank, spray tank body and
Flue, described spray tank body and centrifugal slag remover be separately positioned on the upper and lower of water tank, and spray tank body and centrifugal slag remover equal
Connecting with water tank, described flue gas radiating tube is arranged in water tank, and flue gas radiating tube is arranged on the lower end of spray tank body, flow perturbation fan
Sheet is arranged in water tank, and turbulence blades is arranged on the porch of centrifugal slag remover, and described flue connects with water tank, and spraying mechanism sets
Put the top at spray tank body, connect heat pump heat exchanging coil pipe and flue gas condensing heat exchange coil is arranged in flue from the bottom to top, described
Burner is arranged on the sidewall of spray tank body, and described burner includes primary air fan, venturi powder conveyor, secondary wind
Machine, coal dust suction tube, precombustion chamber and combustor, precombustion chamber and combustion chamber, venturi powder conveyor is arranged on precombustion chamber
Porch, primary air fan is arranged on the porch of venturi powder conveyor, coal dust suction tube and venturi powder conveyor
Connection, be provided with secondary air inlet between combustor and precombustion chamber, overfire air fan is arranged at secondary air inlet, described precombustion chamber and
The outlet of combustor all uses tapering type outlet.
The present invention compared with prior art has the advantages that
One, it is that the air of heating is directly sprayed onto in water tank carries out heat exchange through spray tank body due to the present invention, hot water warp
After three condensations, exhaust gas temperature is down to about 30 DEG C, in being discharged into air；Therefore, the present invention is to conduct with water, conduction
Coefficient is high, purifies Fine coal performance height, environmental protection, desulphurization denitration, decreases air pollution emission.
Two, the burner outlet of the present invention is designed as tapering type outlet, so designs and makes when coal dust enters precombustion chamber,
It can be made to be ignited rapidly under the high-temperature flue gas of Wall Radiation and backflow acts on jointly.It is ignited rear coal dust in combustor
Complete combustion process, discharge heat further, reach the effect burnt completely.
Three, the present invention is in terms of air distribution, and secondary wind is close to precombustion chamber outside wall surface and is entered combustor, and secondary wind can preheat two
Secondary wind can play again protection precombustion chamber wall, slagging prevention scaling loss, supplements oxygen amount and raising burner flame needed for after burning
Rigidity effect；Simultaneously as burner (1) is divided into secondary wind at different combustion phases the air needed for coal dust after burning
Send into so that before not being mixed into secondary wind, owing to oxygen concentration is low, so the NOx produced reduces the most therewith；Secondary wind send into
After, fuel is at air excess region after-flame, although now air capacity is more, but owing to flame temperature reduces, so at secondary
Wind also will not generate more NOx after being mixed into, so that the bar that the Pulverized Coal entered in stove can be oxygen-enriched after first anoxia
Whole burnings and burnout is completed under part, thus, the combustion system of the present invention can reduce whole system nitrogen oxides
Discharge capacity.
Four, dust-removal and desulfurizing is to utilize spraying mechanism to carry out dust-remover, and import flue gas flow rate is big, sprays area top
Space is relatively big, and flue gas produces backflow herein, enhances spraying and the transmission of heat by contact of flue gas and mass transfer.Under steam water interface enters
In the water of Fang Xuanliu, continuing heat exchange, whole process heat exchange efficiency reaches 100%, and efficiency of dust collection reaches more than 98%.Water tank temperature
The lowest, energy-saving effect is the most obvious.
Five, unsuitable too low due to heating hot water, hot water effluent is set in 70 DEG C～90 DEG C by the present invention；Utilize plate-type heat-exchange
Device carries out heat exchange, meets and provides the demands such as hot water for warm.
