In the oil burning industrial boiler, the biomass is taken as substitutional fuel, thereby removing the shortage of fuel resources and reducing the emission of harmful gas.

Description

Living beings replacing oil combustion cyclone furnace
Technical field
The utility model relates to the combustion apparatus boiler technology, particularly a kind of living beings replacing oil combustion cyclone furnace.
Background technology
At present, China has more than 50 ten thousand Industrial Boilers approximately, and annual burning coal is above 400,000,000 tons.The energy utilization rate of most of Industrial Boilers is low, and energy consumption is big, and environmental pollution is serious.In order to protect environment, the small-sized industrial boiler combustion diesel fuel in many cities, but China's oil resource relative shortage, along with rising steadily and the increasingly stringent of environmental requirement of oil price in recent years, the industrial boiler operation cost of combustion diesel fuel is too high.Therefore, this patent proposes to adopt fuel---the living beings of alternative diesel oil, realizes the high performance clean burning of boiler.Living beings directly or indirectly derive from green plants, and in its growth course, living beings are used as power with sunshine, absorb CO by photosynthesis 2, with the form of carbohydrate with carbon fixation in plant, discharge O 2And when living beings by combustion system during as using energy source, the CO that plant is absorbed from atmosphere again 2Discharge.Consider the conversion process of energy of living beings uniqueness in the whole circulation, the CO of biomass burning 2Clean discharging is zero, thereby has realized the CO of biomass energy transfer process 2Zero-emission.Living beings (bamboo bits) sulfur content (<0.2%) and nitrogen content are all very low, and content of ashes is also very little, its burning back SO 2, NOx and dust emissions amount be more much smaller than fossil fuel.Therefore, biomass energy belongs to clean regenerative resource, with living beings (bamboo bits) fuel as an alternative, not only can alleviate the shortage problem of fuel resource, but also can reduce CO in fuel industrial boiler 2, SO X, NO XWith discharge of harmful gases amount such as dust, help to alleviate greenhouse effects, reduce atmosphere pollution, improve the ecological environment.
Summary of the invention
At the problem of above existence, the purpose of this utility model provides a kind of living beings replacing oil combustion cyclone furnace.
The technical solution adopted in the utility model is:
Comprise living beings hopper, screw feeder, airduct, body of heater, secondary air channel, dirt trap, cyclone, micro grease gun igniting device; Living beings hopper, screw feeder and an airduct are formed the biomass granule fuel conveying device, fuel outlet is positioned at the top of body of heater, at the fuel outlet place, be provided with cyclone, the grease gun igniting device is positioned at the middle part of cyclone, the side of body of heater is provided with secondary wind inlet and exhanst gas outlet in secondary wind inlet, secondary air channel, the stove, and dirt trap is positioned at the bottom of body of heater.
Described secondary air channel is made up of outer surface, cyclone furnace surface and the dividing plate of body of heater; Secondary wind inlet in gone out interruption-forming four stoves of even layout of secondary air channel, secondary wind forms an imaginary circle in stove.
Described living beings are bamboo bits, branch, timber leftover pieces, and its particle diameter is less than 5mm.
The beneficial effect that the utlity model has is:
(1) its deslagging mode is a slag tap, can reduce by 50% biomass ash and enter atmosphere;
(2) the strong cyclone firing of living beings, the combustion intensity height, the body of heater volume reduces;
(3) can adopt relatively large biomass granule fuel, reduce the expense that fuel adds man-hour;
(4) high performance clean burning: CO 2Discharging is zero, SO 2Discharge lowly, dust seldom can be without dust arrester.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the A-A cutaway view of the utility model embodiment;
Fig. 3 is the structural representation of the cyclone of the utility model embodiment.
Among the figure: 1. living beings hopper, 2. an airduct, 3. secondary wind inlet, 4. body of heater, 5. secondary air channel in the stove, 6. secondary wind enters the mouth, 7. slag-drip opening, 8. dirt trap, 9. exhanst gas outlet, 10. cyclone furnace surface, 11. dividing plate, 12. cyclones, 13. grease gun igniting devices, 14. fuel outlets, 15. screw feeders.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
As Fig. 1, Fig. 2, shown in Figure 3, the utility model comprises living beings hopper 1, screw feeder 15, airduct 2, body of heater 4, secondary air channel 5, dirt trap 8, cyclone 12, micro grease gun igniting device 13; Living beings hopper 1, screw feeder 15 and an airduct 2 are formed the biomass granule fuel conveying device, fuel outlet 14 is positioned at the top of body of heater 4, at fuel outlet 14 places, be provided with cyclone 12, grease gun igniting device 13 is positioned at the middle part of cyclone 12, the side of body of heater 4 is provided with secondary wind inlet 3 and exhanst gas outlet 9 in secondary wind inlet 6, secondary air channel 5, the stove, and dirt trap 8 is positioned at the bottom of body of heater 4.
Described secondary air channel 5 is made up of outer surface, cyclone furnace surface 10 and the dividing plate 11 of body of heater 4; Secondary wind inlet 3 in gone out interruption-forming four stoves of even layout of secondary air channel 5, secondary wind forms an imaginary circle in stove.Described living beings are bamboo bits, branch, timber leftover pieces, and its particle diameter is less than 5mm.
Operation principle of the present utility model is as follows:
Living beings hopper 1 and screw feeder 15 are transported to diameter in airduct 2 less than the biomass granule fuel of 5mm, and one time wind enters airduct 2 one time from B, carries the strong turning effort of the granular fuel of a wind through cyclone 12, is evenly sent in the stove.Micro grease gun igniting device 13 work produces thermal-flame, lights biomass granule fuel, treat smooth combustion after grease gun igniting device 12 quit work.Secondary wind cools off the outside wall surface of body of heater 4 when C enters secondary air channel 5, makes secondary wind obtain preheating simultaneously.Secondary wind after the preheating is entered in the stove by secondary wind inlet 3 in the stove, forms strong eddy flow wind, makes the biomass granule fuel of having lighted carry out strong whirlwind suspension combustion and adhesion combustion in stove.After biomass granule fuel fully burnt, flue-gas temperature was higher than its ash fusion point, and liquid lime-ash flows into dirt trap 8 from the slag notch 7 of body of heater 4 bottoms.High-temperature flue gas enters boiler heating surface from exhanst gas outlet 9 and carries out heat exchange.
Because biomass granule fuel forms strong cyclone firing in cyclone furnace, the combustion intensity height, burning is complete, makes cyclone furnace structural configuration compactness, and the body of heater volume reduces; Also can adopt the relatively large biomass fuel of particle diameter, reduce the processing charges of granular fuel.Adopt slag tap, the ash content that the lime-ash portability is over half makes that the ash content in the flue gas reduces more than 50%, can reduce the manufacturing cost of cyclone furnace without dust arrester.
