Fig. 2 is a kind of partial enlarged drawing of vertical type biomass boiler.

Embodiment

The technical scheme of this patent is described in more detail with reference to embodiment.

Fig. 1-2, a kind of vertical type biomass boiler, including drum 1, valve jacket 2 and coal bunker 3 are referred to, the lower end of valve jacket 2 is in Funnel-form and center offers slag notch 4, the lower end of valve jacket 2 is also fixedly connected with leg 5, and the drum 1 is fixedly connected on shell In set 2, the upper and lower side of drum 1 is also communicated with filler pipe, outlet pipe and return pipe, and the center of valve jacket 2 is fixedly connected with through drum 1 Burning lumen 6, the also fixed induced duct 7 for being communicated with some groups of arc tubular constructions setting up and down in burning lumen 6 middle part, induced duct 7 every groups are at least four and are arranged circumferentially along drum 1, and induced duct 7 is drawn through drum 1 from its side wall, wherein burning Lumen 6 is also fixedly connected between the deep bead 8 of arc plate structure, two deep beads 8 not in correspondence the top induced duct 7 position Contact, deep bead 8 can play certain drainage, wind is guided into induced duct 7, it is to avoid be blasted when air quantity is excessive in coal bunker 3 And causing coal dust to disperse influence working environment, this is only safety effect certainly, and main or by air blower 12 air quantity is carried out Control；The coal bunker 3 is fixedly connected in the upper end of valve jacket 2, the lower end of coal bunker 3 and the burning close communication of lumen 6, coal bunker 3 and also rotated It is connected between two milling rollers 9, milling roller 9 and is in close contact, is fixedly connected with the rotating shaft of two milling rollers 9 intermeshing Travelling gear, the rotating shaft of right side milling roller 9 is also connected with being fixedly connected on the motor 11 of the upper end of valve jacket 2, is sent by spiral Material machine carries out breaking and Dusting processing by rolling toward input coal charge in coal bunker 3, milling roller 9 to coal dust（For lifting efflorescence effect, two The travelling gear 10 of milling roller 9 can use different wheel footpaths so that the speed of milling roller 9 is different, simultaneously can also be by milling in extruding Lift efflorescence effect）, two scrapers being in close contact respectively with two milling rollers 9 are also fixedly connected with coal bunker 3, will can be sticked to Coal dust on milling roller 9 is scraped, and the coal dust after efflorescence is fallen into burning lumen 6；The right side wall of valve jacket 2 is also fixedly connected with drum Blower fan 12, the air outlet of air blower 12 is connected with the lower end for the lumen 6 that burns by bellows 13, in boiler operatiopn, starts motor 11st, helical feeder and air blower 12, motor 11 and helical feeder complete the efflorescence processing of coal charge, the net combustion chamber of air blower 12 Air blast in pipe 6 so that the coal dust fallen by coal bunker 3 maintains certain altitude and final via induced duct under Wind power propelling effect 7 spray（The air quantity of air blower 12, which should try one's best, ensures near center location of the maximum vertical penetration in drum 1 of coal dust, it is to avoid combustion Firing coal dust is too high and make it that coal bunker 3 bears high temperature and causes internal coal dust firing, and this should be surveyed according to the caliber scene of burning lumen 6 Examination）, burning lumen 6 bottom is also fixedly connected with igniter, and igniter can carry out ignition process to the coal dust on the move that suspends, such as This coal dust can complete burning in moving process with the wind in burning lumen 6 and induced duct 7, and the coal dust subsequently fallen is then by burning Burning coal dust is ignited in lumen 6, because the small oxygen contact surface of coal particle size is big, is burnt very fast, the several seconds is flammable Burn totally, can ensure in the case where the wind speed of air blower 12 is appropriate coal dust can burning lumen 6 and induced duct 7 in moving process In can burn completely, it is to avoid coal dust is wasted, and banking up formula burning with fire grate now can make towards release amount of heat below fire grate Different into wasting, because process of coal combustion is carried out in the centre position of drum 1, its heat is acted on drum 1, effectively carried completely Its combustion efficiency and the efficiency of heating surface are risen, and the high-temperature flue gas after burning can drive cinder from the row of slag notch 4 after gushing out through induced duct 7 Go out（Harmful substance is few in bio-coal waste gas, and the biomass cinder produced that burns can then make as biomass fertilizers are secondary With, therefore need not typically be equipped with flue gas processing device, it is only necessary to it is equipped with a cinder collection device）, in high-temperature flue gas flowing During the side wall of drum 1 can also be heated, be further opened with cleaning door effectively using its waste heat, on the left of the bottom plate of bellows 13 14, the bottom plate of bellows 13 slidably connects sealing baffle 15, the surface side wall of sealing baffle 15 4 and the correspondence of bellows 13 at cleaning door 14 Place is covered with asbestos seal pad, ensures its air-tightness when sealing baffle 15 is closed, it is to avoid air blower 12 blasts wind and spilt, close The lower end of block plate 15 is fixedly connected with the pull bar 16 for drawing valve jacket 2, promotes pull bar 16 easily to open pass by left and right Sealing baffle 15 is closed, can be by opening sealing baffle 15 while coordinating air blower 12 when accumulation has coal dust cinder in bellows 13 Blow convenient progress internal cleaning.

The better embodiment to this patent is explained in detail above, but this patent is not limited to above-mentioned embodiment party , can also be on the premise of this patent objective not be departed from formula, the knowledge that one skilled in the relevant art possesses Make a variety of changes.
