Abstract
The utility model discloses a water vapor gasifying heating system by waste heat of biomass. The system comprises a bunker, a gasifying furnace, a spiral conveyer, an assistant reaction tower, a cyclone separator and a heating furnace, wherein an outlet of an exhaust pipeline of the heating furnace is connected with a waste heat boiler which heats water vapor generated by water by means of heat generated by waste head smoke, wherein the water vapor is input to the gasifying furnace to involve in an air-water vapor gasifying reaction. The flow and heat value of the biomass fuel are improved, and the fuel amount is saved, smoke which is discharged by the heating furnace and cooled to below 250 DEG C by the waste heat boiler is then discharged, so that the problem of blocking an air preheater and a rear smoke channel is solved, the problem of positive pressure of the heating furnace is effectively solved, and the heating capacity of the heating furnace is improved.
Description
Technical field
The utility model relates to a kind of gasifying biomass heating field, specifically relates to a kind of gasification heating system of utilizing remaining thermogenetic water vapor participation air-vapor gasification reaction.
Background technology
Chinese patent literature CN102367392A discloses a kind of biomass air-vapor gasifying system, and the biological fuel gas that described gasifier produces can be for industry heating application.Biological fuel gas is because calorific value is high, preparation cost is low, and carbon dioxide zero discharge, makes it replace traditional energy product.
In actual production, biological fuel gas produces heat energy by burning in process furnace.Process furnace is at high temperature operation conventionally, and the thermosteresis of smoke evacuation reaches more than 30%, wastes a large amount of heat energy; And too high funnel temperature also can cause induced draft fan fluctuation of service.In order to protect induced draft fan; conventionally on the process furnace back-end ductwork before induced draft fan, join a cold blast engine to reduce funnel temperature; thereby cause induced draft fan not enough to the draft of heating inner flue gas of the stove; in air preheater and process furnace back-end ductwork, dust stratification seriously results in blockage; heating inner flue gas of the stove can not be taken away in time by induced draft fan; form malleation, not only wasted energy but also caused that workshop Dust Capacity is large, operating environment is poor.
Utility model content
The utility model, in order to overcome the problem existing in existing technique, provides a kind of waste heat of flue gas of heating furnace that can effectively utilize to produce steam for the biomass gasification system of vapourizing furnace.
In order to realize above object, the technical solution of the utility model is: a kind of biomass remaining hot water steam gasification heating system, comprise the feed bin that holds biomass fuel, biomass fuel combustion gasification reaction produces the vapourizing furnace of biological fuel gas, biomass fuel is input to the worm conveyor of vapourizing furnace from feed bin, strengthen the side reaction tower of gasification, remove the cyclonic separator of lime-ash, biomass fuel gas firing produces the process furnace of heat energy, the smoke discharging pipe outlet of described process furnace connects waste heat boiler, in the water vapor input vapourizing furnace that waste heat boiler utilizes the heat heating water of waste heat flue gas generation to produce, participate in air-vapor gasification reaction.
Compared with prior art, the utility model, by increasing waste heat boiler at process furnace back-end ductwork, is supplemented to vapourizing furnace by the saturated vapor more than needed producing, and makes it in vapourizing furnace, participate in air-vapor gasification reaction, improve flow and the calorific value of biological fuel gas, fuel economy amount.
Increase after waste heat boiler, utilized the heat energy of process furnace smoke evacuation to add thermogenesis water vapor supply vapourizing furnace to feedwater, and then after being dropped to below 250 ℃ after waste heat boiler, process furnace funnel temperature discharges again, be enough to guarantee that induced draft fan normally moves, therefore dismountable cold blast engine, to improve the draft of induced draft fan, thereby solves the problem of air preheater and back-end ductwork obstruction, effectively solve the malleation problem of process furnace, improve the heating efficiency of process furnace.
In addition, because the air-vapor gasification reaction in vapourizing furnace is thermo-negative reaction, adding of remaining hot water steam can be played reduction biological fuel gas temperature, has regulatory function, increases the security of gasifier operation.
Accompanying drawing explanation
Fig. 1 is biomass remaining hot water steam gasification heating system figure.
Below in conjunction with accompanying drawing and most preferred embodiment, the utility model is described in further details.
Embodiment
As shown in Figure 1, biomass remaining hot water steam gasification heating system is comprised of feed bin 1, screw feeder 2, vapourizing furnace 3, side reaction tower 4, cyclonic separator 5, process furnace 6, waste heat boiler 9 and induced draft fan 8.
The required fuel of vapourizing furnace 3 combustion reactionss is inputted by worm conveyor 2 by feed bin 1, need in vapourizing furnace 3, send into air by gas blower 11 simultaneously.
The biological fuel gas that vapourizing furnace 3 produces enters side reaction tower 4, to increase the gasification reaction time, makes gasification reaction more abundant.
Cyclonic separator 5, by after side reaction tower 4 biomass gas purifying out, enters process furnace 6 burnings and produces heat energy for industrial production.
The lime-ash that side reaction tower 4 and cyclonic separator 5 produce is discharged by residue extraction machine 10.
The waste heat boiler 9 that rated capacity is 6t/h of smoke discharging pipe outlet access of process furnace 6, simultaneously to waste heat boiler 9 input water.In waste heat boiler, after 550～600 ℃ of waste heat flue gas heating that water is recovered, produce the saturated vapor of pressure 0.7MPa, 170 ℃ of left and right of temperature.Water vapor is input in vapourizing furnace 3, participates in air-vapor gasification reaction, by carbon monoxide and hydrogen content in the gasification reaction increase combustion gas of water vapor and carbon, to improve biomass fuel airshed and calorific value.After waste heat flue gas is utilized, from waste heat boiler, by induced draft fan 8, extracted out, outflow temperature drops to below 250 ℃.
