Description
Technical field
The utility model belongs to technical field of combustion equipment, is specifically related to a kind of low heat value liquid state, solid flow fluidized bed boiler.
Background technology
At present, the technology that low heat value solid fuel utilizes fluidized-bed combustion boiler to burn is ripe, but low heat value liquid fuel as calorific value 1200 kilocalories/kilogram the liquid fuel technology that utilizes fluidized-bed combustion boiler to burn also need research, test, and these low-calorie liquid fuels as changing food waste, chemical plant quench get solvent, quenching of pharmaceutical factory is got solvent etc. and is needed that we are turned waste into wealth, environmental protection treatment.
Summary of the invention
Technical problem to be solved in the utility model is: solve above-mentioned prior art Problems existing, and a kind of low heat value liquid state, solid flow fluidized bed boiler are provided, can not only lower heat of combustion solid fuel, and can lower heat of combustion liquid fuel, for changing food waste a large amount of in our daily life and chemical plant, pharmaceutical factory low heat value liquid fuels such as getting solvent of quenching carries out environmental protection treatment, turn waste into wealth, for people life, produce new heat energy is provided.
The technical solution adopted in the utility model is:
A kind of low heat value is liquid, solid flow fluidized bed boiler, comprise fluid bed body of heater, the bellows of fluid bed bottom of furnace body, air distribution plate and blast cap, the exhaust gases passes at fluid bed body of heater top and outlet flue, the torch oil gun that fluid bed furnace body side surface is connected and installed and screw(-type) feeder; Certain thickness quartz sand bed material or slag bed material is filled with in the burner hearth of the utility model on air distribution plate and blast cap, fluid bed body of heater is not for establish heated face structure, hearth wall above air distribution plate, blast cap is shaped to the vertical section of certain altitude, meanwhile, solid fuel material inlet and liquid fuel dispersive nozzle is also connected and installed with at fluid bed furnace body side surface.
In technique scheme, the quartz sand bed material of filling in the burner hearth above described air distribution plate and blast cap or slag bed material thickness are 0.9-1.1 meters.
In technique scheme, described bellows are isobaric bellows.
In technique scheme, described fluid bed body of heater is not for establish heated face structure specifically: body of heater shell adopts heat-resisting steel sheet and plate and steel plate inside to mix a certain amount of wear-resisting pouring material by heat-resisting bitch and is connected and fixed formation.
The utility model has 4 most important improvement on the basis of existing combusting solids fuels fluidized-bed combustion boiler:
One is that in the burner hearth on air distribution plate, blast cap, filled stone sand or slag make bed material, like this, first with torch oil gun, bed material can be heated, make the liquid fuel of atomization meet bed material namely by ignition, simultaneously also for INVENTIONLiquid-fueled combustion be provided with one combustion fluidized bed.Owing to there being this certain amount of bed material, also just store a certain amount of heat, although inferior value heat output of fuel is lower, also can ensure stable burning.
Two is that body of heater of the present utility model does not establish heated face structure, namely be not provided with circulating water pipe, prevent heating surface from reducing the temperature of burner hearth like this, avoid the heat disperseing burner hearth, make the ignition temperature of burner hearth high, for low calorie fuels has prepared condition in burner hearth combustion, lay the foundation, make burner hearth good heat insulation, although low heat output of fuel inferior is low, still can ensure smooth combustion in burner hearth.
The utility model burner hearth is made with certain volume simultaneously, flue gas is made to keep the regular hour in burner hearth, by fuel after-flame, back-end ductwork is entered again by outlet flue, by afterbody heat exchanger by energy in addition heat exchange utilize, last afterbody by gas cleaning, accomplishes qualified discharge by soot processing device.
Three is the utility model lower furnace portion moulding above air distribution plate is the vertical section of certain altitude, and this moulding makes quartz sand bed material or slag bed material be risen by bottom wind, and fluidisation is even, and thus fuel burns very stable thereon.And the burner hearth above its air distribution plate of traditional fluidized-bed combustion boiler is taper bucket structure, after bed material is risen by bottom wind in taper bucket, upper lower density differs, and is diffused, and thus fuel burning is thereon very unstable, and combustion efficiency is poor.
Four is that the utility model is provided with liquid fuel dispersive nozzle on body of heater, and low heat value liquid fuel is relevant with arranging of its atomising device in the quality of burner hearth combustion situation, and therefore, the setting of liquid fuel dispersive nozzle is one of feature of the present utility model.
Boiler furnace of the present utility model is also provided with another solid fuel material inlet, solid fuel can be carried in stove.Therefore the utility model both can the low poor quality of single fire liquid fuel (net calorific value as received basis 1200 kilocalories/kilogram more than), also can the low poor quality of single fire solid fuel (net calorific value as received basis 800 kilocalories/kilogram more than), can also the low solid fuel inferior of multifuel combustion, liquid fuel fuel combination (comprehensive net calorific value as received basis 1200 kilocalories/kilogram more than).
Therefore, the utility model is multiple functional, enables changing food wastes a large amount of in our daily life and chemical plant, the low heat value liquid fuels such as getting solvent of quenching of pharmaceutical factory carries out environmental protection treatment, turn waste into wealth, energy-saving and emission-reduction, for people life, produce new heat energy is provided.
