Description
Technical field
The utility model relates to boiler, particularly a kind of boiler of the impurity can removed in biomass fuel.
Background technology
Biomass fuel, as a kind of novel regenerative resource, because its calory burning is high, is easily taken care of, is easily transported, pollution-free, and is widely used.In recent years, biomass fuel was also applied in boiler industry.Because biomass fuel is by many kinds of substance fragment, make through stirring fermentation etc., be easy to produce larger bulk, the fuel of this larger bulk is nonflammable, this reduces the combustion rate of fuel, also affects the thermal efficiency of boiler.In the past be that coal is sent in combustion chamber by artificial or conveyer belt by the boiler of fuel mostly with coal, this structure is not very applicable to biomass fuel.
Summary of the invention
For the deficiencies in the prior art, the purpose of this utility model is to provide one can be broken up before biomass fuel enters combustion chamber, is conducive to biomass fuel and easily carries and burn.
The utility model provides following technical scheme:
Can remove a boiler for the impurity in biomass fuel, comprise combustion chamber and screw(-type) feeder, the discharging opening of described screw(-type) feeder is arranged in combustion chamber, and described combustion chamber sets out burner away from discharging opening side; Described combustion chamber is made up of inner bag, is arranged to dead level chuck between inner bag and shell; The air outlet of blower fan is communicated with the bottom of combustion chamber and feed cylinder are interior, and be also communicated with away from crater side with dead level chuck, dead level chuck is provided with opening near crater place; The air outlet of described blower fan is communicated with away from crater side with combustion chamber; Screw(-type) feeder replaces in the past with manually adding fuel, and hand labor intensity reduces, and can continuous feeding, makes flame combustion stable.Be communicated with in the air outlet of blower fan and the feed cylinder of screw(-type) feeder, protect feeding system and do not burnt out by high temperature, avoid feeding system to fall the problem of over-emitting black exhaust.Dead level chuck is designed between inner bag and shell, in normal work, the temperature of inner bag is very high, inner bladder outer wall outwards can spread heat, wind is sent in dead level chuck by blower fan, dead level chuck apoplexy fully absorbs the waste heat that inner bag outwards falls apart, improve the temperature of wind at opening part, combustor exit, owing to having wind and the fire fully mixed combustion again of high temperature, makes the temperature of combustor exit greatly improve.Top in the hopper of screw(-type) feeder arranges the dividing plate of multiple right-angled intersection, is separated the biomass fuel entered in hopper, makes it looser, is conducive to its Thorough combustion in combustion chamber.Dividing plate is fixedly installed magnet, a small amount of metal impurities be mingled with can be adsorbed on magnet in biomass fuel, and then avoid damaging the helical axis in feed cylinder, do not affect the efficiency of combustion of biomass fuel.
Further, the dismountable top be arranged in hopper of described dividing plate.
Preferably, described screw(-type) feeder is driven by frequency control motor.By frequency control motor drive in screw(-type) feeder helical axis swivel feeding, the speed of feeding controls the size of variable frequency adjustment feed with the pressure height of the temperature of boiler height or steam boiler.
Preferably, described blower fan is driven by variable-frequency motor.Frequency control motor is adopted to control the size of the air output of blower fan.

Detailed description of the invention
Below in conjunction with accompanying drawing, a most preferred embodiment of the present utility model is described further, to help understanding content of the present utility model.
Can remove a boiler for the impurity in biomass fuel, comprise combustion chamber 1 and screw(-type) feeder 2, the discharging opening 3 of described screw(-type) feeder 2 is arranged in combustion chamber 1, and described combustion chamber 1 sets out burner 4 away from discharging opening 3 side; Described combustion chamber 1 is made up of inner bag 7, is arranged to dead level chuck 9 between inner bag 7 and shell 8; The air outlet of blower fan 5 is communicated with feed cylinder 6 is interior with the bottom of combustion chamber 1, and be also communicated with away from crater 4 side with dead level chuck 9, dead level chuck 9 is provided with opening 10 near crater 4 place; The air outlet of described blower fan 5 is communicated with away from crater 4 side with combustion chamber 1; Screw(-type) feeder 2 replaces in the past with manually adding fuel, and hand labor intensity reduces, and can continuous feeding, and flame combustion is stablized.The air outlet of blower fan 5 is communicated with in the feed cylinder 6 of screw(-type) feeder 2, protects feeding system and is not burnt out by high temperature, avoids feeding system to fall the problem of over-emitting black exhaust.Dead level chuck 9 is designed between inner bag 7 and shell 8, in normal work, the temperature of inner bag 7 is very high, inner bag 7 outer wall outwards can spread heat, wind is sent in dead level chuck 9 by blower fan 5, wind in dead level chuck 9 fully absorbs the waste heat that inner bag 7 is outwards loose, improve the temperature of wind at opening 10 place, combustion chamber 1 exports wind and fire fully mixed combustion again owing to there being high temperature, and the temperature that combustion chamber 1 is exported improves greatly.The dismountable dividing plate 12 arranging multiple right-angled intersection in top in the hopper 11 of screw(-type) feeder 2, is separated the biomass fuel entered in hopper 11, makes it looser, is conducive to its Thorough combustion in combustion chamber.Dividing plate 12 is fixedly installed magnet, a small amount of metal impurities be mingled with can be adsorbed on magnet in biomass fuel, and then avoid damaging the helical axis in feed cylinder 6, do not affect the efficiency of combustion of biomass fuel.
Specific works mode
Screw(-type) feeder 2 under the driving of frequency control motor, according to the pressure height of the temperature of boiler height or steam boiler control variable frequency adjustment feed number; Blower fan 5 is under the driving of frequency control motor, and the temperature height according to boiler controls air output; The efficiency of combustion of control combustion room 1 endogenous substance fuel.
