The specific embodiment
The most preferred embodiment of the utility model is such: with reference to accompanying drawing 1~Fig. 5, this incinerator comprises by main stove, air preheater, water collar, device for abatement of smoke and dust etc. and constituting.Fuel, rubbish add through the feeding mouth at boiler top, and the preheating section in the guide cover is by preheating.Is fuel gas in the gasification cracking section by pyrolysis gasification, and attracted to furnace combustion zone.Guide cover is placed the frame mode in the burner hearth, and compact conformation can gasify, the noxious material in the cracking rubbish simultaneously.In the combustion zone fuel gas and not vaporized combustible and from the air of hot blast spray orifice and the ejection of fire grate spray orifice acutely burn, completing combustion.The wind mode that adds like this, promptly the frame mode at the hot blast spray orifice of inboard wall of burner hearth periphery can make fuel combustion evenly, fully.Fuel, rubbish burn on travel(l)ing grate, and fire grate is taper and rotatable, the also available fixed grate of fire grate; This mode reduces fireman's labour intensity greatly; Make burning velocity stable, controlled simultaneously, multiple switching fire door, ash door number of times reduce excess air factor when reducing manual stoker; Reduce heat loss, the raising boiler thermal output of boiler, travel(l)ing grate has spray orifice makes burning more abundant.The thermal radiation of burning has heated fuel, the rubbish in the guide cover, makes its preheating, gasification, cracking, and the water in the heating boiler produces steam or hot water simultaneously, supplies to use with vapour unit.High-temperature flue gas arrives fume collecting chamber through the tube bank of boiler fire tube, and boiler water tube tube bank in the flue and the tube bank of boiler fire tube are heated and heat is conducted to the water in the boiler, produce steam or hot water.Flue gas in the fume collecting chamber arrives air preheater through fume pipe, has the secondary wind inlet on the fume pipe, and from then on the overfiren air port air of coming in burns the unburnt gas in the fume pipe once more.The setting of secondary wind-supplying mouth structure makes that unburnt fuel gas particle burns once more in the flue gas, guarantees the abundant burning of fuel, reduces pernicious gas and material.High-temperature flue gas heats the barrel and the transverse tube of inner bag through the inner bag of air preheater, and the heat of barrel and transverse tube conducts to the cold air of opposite side, and cold air becomes hot-air after absorbing heat, is pressed in the boiler furnace combustion fuel and rubbish by air blast.The flue gas that comes out from air preheater gets into water collar further by water-cooled but, and the transverse tube in the water collar has increased the area of cooling, and just cooling effectiveness is higher, becomes hot water after cooling water is heated and is sent in the boiler and uses.This structure can be regained boiler to the heat in the high-temperature flue gas and use, and has improved the thermal efficiency of boiler, protects air-introduced machine simultaneously.The flue gas that comes out from water collar is pressed onto the dust storage chamber of device for abatement of smoke and dust by air-introduced machine, the steam humidification that flue gas is come by boiler, and dust in flue gas is free settling and absorption more.Dust in flue gas is deposited to dust storage chamber, is adsorbed when the dust of sedimentation is not upwards through smoke abatement and dust control thing layer, and remaining flue gas is cleaner, and is discharged or delivers to desulfurizer and further purify.The smoke precipitator structure that adds steam makes flue dust be easier to sedimentation and absorption.Main stove (7) inner chamber is equipped with guide cover

pipe (15) to be connected between second gas approach (44) of water collar (12) and second smoke inlet (58) of device for abatement of smoke and dust (21).The steam import (60) of device for abatement of smoke and dust (21) exports between (36) with the Boiler Steam of main stove (7) has steam pipe (9) to be connected.Steam pipe (9) is equipped with steam valve (10), and steam valve (10) has two, and one meets the user, and another is switched to the steam import (60) of device for abatement of smoke and dust (21).Device for abatement of smoke and dust (21) is equipped with chimney (18), and device for abatement of smoke and dust (21) inner chamber is equipped with the first smoke abatement and dust control thing (20) of carbon, sandstone, fiber, filter screen and so on.Guide cover (34) bottom nozzle to travel(l)ing grate (39) section is a burning block, and the burning block top is the gasification cracking section, and the top is the preheating section again, and preheating section top is the bed of material.First steam (6) is first hot water (5) under first steam (6) on main stove (7) inner chamber top, and first hot water (5) communicates with boiler water tube (61).Boiler fire tube (35) is in the interlayer of first hot water (5).Water collar (12) and air preheater (25) buyable also can be made by oneself.Device for abatement of smoke and dust (21) intracavity bottom is dust storage chamber (54), and the middle part is the second smoke abatement and dust control thing (56), and the top is clean smoke chamber (57).Turbogrid plates (55) are installed in the middle of the inner chamber of device for abatement of smoke and dust (21), put the second smoke abatement and dust control thing (56) on Turbogrid plates (55) face, and the first fume and dust thing (20) and the second smoke abatement and dust control thing (56) are same thing.The utility model environmental protection and energy saving are burnt the useless flue gas of burner through the secondary air burning, reach abundant burning.The boiler fire tube is used counter-burning type, filters useless flue gas, purify through air preheater and water collar to device for abatement of smoke and dust through fume collecting chamber, meets or exceeds the environmental requirement of national regulation fully, reaches fast energy-saving, purification environmental-protection effect.
