The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
The label of each parts is among the figure, 1 annular water conservancy diversion arch, 2 drying layers, 3 destructive distillation layers, 4 reducing zones, 5 oxide layers, 6 coke after-flame layers, 7 water seal tanks, 8 hand moving grates, 9 slag layers, 10 ash tubes, 11 air channels, 12 blower fans, 13 water inlet pipes, 14 times circulation pipes, 15 wireways, 16 perpendicular air channels, 17 gas producers, 18 water jackets, 19 tuyeres, 20 combustion chambers, 21 cleaning doors, 22 dust-settling compartments, 23 deflectors, 24 dedusting caps, 25 chimneys, 26 smoke-box outlet flues, 27 water pressure gauges and relief valve connection, 28 outlet pipes, 29 bodies of heater, 30 hydroeciums, 31 heat pipes, 32 smoke-boxes, 33 threaded flues, 34 upper circular tubes, 35 annular passages, 36 coal bunker seal covers, 37 coal bunkers, 38 dispensers, 39 coal feeding pipes, 40 seed regions, 41 blow-off pipes.
Referring to accompanying drawing, this boiler comprises body of heater 29, blower fan 12, air channel 11, secondary air duct 44, body of heater 29 comprises hydroecium 30, combustion chamber 20, chimney 25 and fire grate 8 again, be provided with gas producer in the combustion chamber 20,20 of the gas producer 17 of gas producer and combustion chambers are provided with wireway 15, the coal bunker 37 that coal feeding pipe 39 outer ends and of gas producer 17 are provided with seal cover 36 links to each other, coal bunker 37 also is provided with dispenser 38, gas producer 17 lower ending openings are relative with hand moving grate 8, and body of heater 29 lower ends are provided with water seal tank.The housing of gas producer is a water jacket 18, and water jacket 18 is provided with upper circular tube 34 and the following circulation pipe 14 that is communicated with 30 of hydroeciums.Be provided with smoke-box 32 in the hydroecium 30, smoke-box 32 is provided with the threaded flue 33 that is communicated with 20 of combustion chambers, be provided with heat pipe 31 in the smoke-box 32, the outlet flue 26 of smoke-box 32 links to each other with the dust-settling compartment 22 that is provided with deflector 23 and dedusting cap 24, establish chimney 25 on the dust-settling compartment 22, divide into ash tube 10, side is opened cleaning door 21, and ash tube 10 under sheds are communicated with water seal tank 7.Hydroecium 30 bottoms are provided with blow-off pipe 41, and blow-off pipe 41 lower ending openings are communicated with water seal tank 7.In addition, hydroecium 30 also is provided with water inlet pipe 13, outlet pipe 28 and water pressure gauge 27 and relief valve connection etc.Fire grate 8 is provided with annular water conservancy diversion arch 1.Air channel 11 openings are below fire grate 8, and secondary air duct 44 is communicated with perpendicular air channel 16 and annular passage 35.Tuyere 19 tilts in the same way, and it is communicated with annular passage 35 and is fixing, and tuyere 19 openings are located in the combustion chamber 19.First and second air channel 11,44 respectively is provided with air quantity damper 42,43.
When using this boiler, coal should keep a Room height, naked light must not occur and burn phenomenon.Water in the water seal tank 7 not only seals to boiler, and plays the safeguard protection effect that prevents coal gas detonation pressure release.In addition, fervid slag continuously falls into pond 7, make the water temperature rising and produce a large amount of steam, after steam and a wind are mixed into hot blast, pass fire grate 8 and slag layer 9, enter coke after-flame layer 6, in this layer, part steam is decomposed into H2 and O2 rapidly under the condition of high temperature, wherein, and small part O2 and coke generation oxidation reaction, and the formation naked light passes seed region 40, enter combustion chamber 20, form ignition flame, light at any time from the coal gas of gas producer 17 through wireway 15 ejections.
After a large amount of wind and steam pass coke burning zone 6, enter oxide layer 5, violent oxidation reaction can take place and emit a large amount of heat.When the great amount of carbon dioxide gas that produces in the oxide layer 5 passes through reducing zone, under the high temperature anaerobic condition, generate a large amount of CO gas with charcoal generation reduction reaction.Reducing zone up is the destructive distillation layer, and it separates out fugitive constituent, generates coke or semi-coke simultaneously, and this layer temperature is generally about 400-500.Up be drying layer 2 again, this layer temperature is lower, and fire coal is heated and evaporates moisture content, and its temperature is generally about 100-200.In gas producer 17, because making between this chamber and the combustion chamber 20, the continuous increase of coal gas amount forms pressure reduction, coal gas continuously sprays to combustion chamber 20 by wireway 15 under this differential pressure action.Secondary wind tangentially sprays in the combustion chamber 20 through annular passage 38 and tuyere 19 after being heated to form hot blast through perpendicular air channel 16 again, forms strong rotating field, and secondary wind and coal gas fully mix and ignition under the effect of rotating field.Because the effect of rotating field, the coal gas rotary combustion, prolong at residing time in furnace, it is more abundant to burn, and has eliminated the root that produces black smoke, and this has just realized the incorporate clean combustion of coal gas in the boiler, what be that boiler adds is coal, what burn is gas, has changed the burning structure of boiler effectively, has improved combustion rate and smoke medicining dust-removing effect.According to coal and ruuning situation, secondary wind independent regulation respectively reaches optimum state so that burn.
The radiation heating-surface of the water jacket 18 housing double as boilers of gas producer has not only improved the heat-transfer effect of boiler, also saves the steel consumption simultaneously, has reduced manufacturing cost.Adopt heat pipe 11 and threaded flue 33 these two kinds of high-performance heat transfer components, the boiler heat-transfer effect is improved greatly.
After the gas-fired, the thermal-flame and the flue gas of formation advance with spiral status, enter smoke-box 32 by threaded flue 33 in the stove, and then enter in the dust-settling compartment 22, under the effect of deflector 23, flue gas turns to up, enters atmosphere through entering chimney 25 behind the dedusting cap 24 again.Dust in the dust-settling compartment 22 can reach the purpose of automatic ash removing in ash tube 10 falls into water seal tank 7 automatically.The effect one of threaded flue 33 is efficient heat transfer, the 2nd, and flue gas helical form in pipe is flowed, destroyed the boundary layer of flue gas, be difficult for dust stratification.Heat pipe 31 also has two effects, and the one, the heat exchange efficiency height, the 2nd, make flue gas transversal flow heat pipe outer wall, help dedusting.
The temperature that annular water conservancy diversion arch 1 has improved in the stove has changed the direction of seed region flame, helps the coke after-flame, and can stop flying upward of dust in the slag layer 9 effectively.
Sewage directly enters in the water seal tank 7 by blow-off pipe 41, has both reduced heat loss, has also alleviated pollution.
The same with common boiler, also be provided with the fire door (not shown) in the bottom of this boiler, so that the slag removal of bulk sintering can be come out.
