As shown in Figure 5, the cross section of combustion barrel 330 is rounded, also can be arranged to square or rectangle as required.The warm water entrance 311 once spraying Heat Room 300 is connected by the exit end of pipeline with the heat exchange coil 520 in aluminium material oxidation pond 500, the water of about 50 degrees Celsius from the exit end of heat exchange coil 520 enters once spray Heat Room 300 from warm water entrance 311, and the hole on shower plate 320 sprays formation water smoke downwards, first water smoke carry out direct heat exchange with high-temperature flue gas, then the bottom once spraying Heat Room 300 is collected in, the water logging collected there is not combustion barrel 330 and again realizes heat exchange with the barrel of combustion barrel 330, the temperature of water is elevated to about 80 degrees Celsius, and discharge from the hot water outlet 312 a spray chamber body 310, from the hot water of hot water outlet 312 under the suction function of water pump 600 via Cemented filling to the inlet end of the heat exchange coil 520 in aluminium material oxidation pond 500.
In operational process, water forms circulation loop between the heat exchange coil 520 once spraying Heat Room 300 and aluminium material oxidation pond 500, water absorbs the heat of high-temperature flue gas in Heat Room 300 once spraying, when water flows through aluminium material oxidation pond 500, again to aluminium material oxidation pond 500 release of heat, oxidation liquid medicine is wherein heated.When water flows between the heat exchange coil 520 in aluminium material oxidation pond 500 and spray Heat Room 300, along with discharge and the evaporation of water process of high-temperature flue gas, the water yield can constantly reduce, and therefore needs make up water at any time, prevents combustion barrel dry combustion method.The water supplemented enters from water supplement port 315 and once sprays Heat Room 300.In this non-limiting embodiment, water supplement port 315 above the combustion barrel 330 once sprayed in Heat Room 300 with middle temperature exhanst gas outlet 314 below position be located at and once spray on a sidewall of Heat Room 300.
In addition, as shown in Figure 5, another sidewall once spraying Heat Room 300 is provided with overflow port 316 near the position of shower plate 320, when once spraying the water excess in Heat Room 300, if the water surface reaches the height of overflow port 316, then unnecessary water is discharged by overflow port 316 and is once sprayed outside Heat Room 300, prevents the water surface from flooding the flue gas manifold 3311 on smoke exhaust pipe 331 and causing smooth and easyly discharging fume.In this non-limiting embodiment, in the short transverse once spraying Heat Room 300, be followed successively by by sequence of positions from top to bottom: combustion barrel 330, water supplement port 315, overflow port 316, flue gas manifold 3311, middle temperature exhanst gas outlet 314 and shower plate 320.
Secondary spraying Heat Room 400 comprises secondary spraying room body 410, secondary spraying room body 410 is provided with cold water inlet 411, middle temperature smoke inlet 412, low-temperature flue gas outlet 413, secondary hot water export 414 and be arranged on the cold water spray header 415 of body 410 inside, secondary spraying room, flue gas exhausting pipe line 416 is connected in low-temperature flue gas outlet 413.Cold water enters secondary spraying Heat Room 400 by cold water inlet 411, and is sprayed in secondary spraying room body 410 by cold water spray header 415.Secondary spraying Heat Room 400 is entered via middle temperature smoke inlet 412 from once spraying the high-temperature flue gas that Heat Room 300, warm exhanst gas outlet 314 is discharged, the cold water ejected with cold water spray header 415 wherein carries out heat exchange, the heat that cold water fully absorbs high-temperature flue gas becomes hot water, export 414 discharges from secondary hot water subsequently, and high-temperature flue gas discharges system from low-temperature flue gas outlet 413 after heat exchange.
The flue-gas temperature that warm smoke inlet 412 enters from secondary spraying Heat Room 400 is approximately 80 DEG C, and the hot water temperature exporting 414 discharges from the secondary hot water of secondary spraying Heat Room 400 is approximately 50 DEG C.Secondary hot water exports 414 and is connected with the water supplement port 315 once spraying Heat Room 300, and hot water exports 414 from secondary hot water and flows to water supplement port 315, and enters into once spray Heat Room 300 inside.First water as heat transferring medium enter circulation from the cold water inlet of secondary spraying Heat Room, the water entered from here in addition constantly can also replenish the water yield once spraying circulation loss in Heat Room 300 and aluminium material oxidation pond 500 and the water yield taken away by flue gas, stablize with the quantity of circulating water being kept for the aluminium 900 heated in aluminium material oxidation pond 500, thus ensure good aluminium material oxidation effect.
In addition, the flue gas exhausting pipe line 416 of secondary spraying Heat Room 400 is arranged backflow flue gas outlet 4165, the blast inlet 1121 that backflow flue gas outlet 4165 overlaps 112 by pipeline and the wind of biomass gasifying furnace 100 is connected, because flue gas contacts and heat exchange with large water gaging once spraying in Heat Room 300 and secondary spraying Heat Room 400, therefore be rich in steam in flue gas, and the temperature of flue gas drops to about 60 DEG C.In addition, supplementary air in the pipeline between the blast inlet 1121 overlap 112 by blower fan 800 to backflow flue gas outlet 4165 and the wind of biomass gasifying furnace 100, to improve the oxygen level of backflow flue gas.And be separately provided with blower fan 700 in the pipeline between the blast inlet 1121 overlapping 112 in backflow flue gas outlet 4165 and the wind of biomass gasifying furnace 100, to attract to be rich in the direction flowing towards wind cover 112 of the flue gas of steam and outside air, thus make the vaporized chemical being rich in steam and oxygen enter wind to overlap 112, through entering in body of heater 110 by reaction gas inlet 1113 after vaporized chemical overlaps 112 preheatings from wind subsequently, to promote the gasification reaction of biomass material thus to produce biogas.
As shown in Figure 1, aluminium material oxidation pond 500 is for the oxidizing reaction of aluminium 900, the oxidation of aluminium needs to keep certain temperature and is immersed in by aluminium in oxidation liquid medicine to complete, and therefore needs that oxidation liquid medicine is warmed up to certain temperature and could obtain good oxidation effectiveness.Aluminium material oxidation pond 500 comprises the pond body 510 holding aluminium 900 and oxidation liquid medicine and the heat exchange coil 520 be arranged in pond body 510, heat exchange coil 520 has inlet end 521 and exit end 522, inlet end 521 is connected with the hot water outlet 312 once spraying Heat Room 300 by pipeline, and exit end 522 is connected with the warm water entrance 311 once spraying Heat Room 300, thus form water-flow circuit once spraying between Heat Room 300 and heat exchange coil 520, water pump 600 is also provided with to improve pressure and the speed of water flow between hot water outlet 312 and inlet end 521.Heat exchange coil 520 is set to bending multiple pipeline arranged in parallel or is set to the shape of annular array in the bottom in aluminium material oxidation pond 500, to increase heat exchange area, thus the heat of hot water is passed to oxidation liquid medicine efficiently, the hot water temperature entering heat exchange coil 520 is approximately 80 DEG C, and is approximately 60 DEG C from the hot water temperature that heat exchange coil 520 is discharged.Hot water gets back to the heat once spraying and once more absorb high-temperature flue gas after heat exchange chamber 300, and temperature rises to about 80 DEG C again, and cycle heat exchange in the loop again.Water as heat transferring medium can obtain heat continuously from the flue gas of a spray heat exchanger 300 and secondary spraying interchanger 400, thus by carry heat to the oxidation liquid medicine in aluminium material oxidation pond 500, realize the high temperature oxidation of aluminium, meet the temperature requirements of oxidizing reaction.
