Description
The utility model relates to the downdraft solid organic castoff vapourizing furnace that a kind of refuse treatment is used.
The direct burning of solid organic castoff brings the serious environmental pollution problem easily.Chinese patent 98243726.9 disclose a kind of downdraft biomass gasifying furnace, this furnace body is a connection mode structure up and down, and top is burning portion, and the bottom is an assisted parts, there is opening for feed on burning portion top, outer wall has insulating sandwich, and the burner hearth of burning portion is the platform of falling a garden shape, and vapor chamber, air chamber are set in the body of heater, the assisted parts outer wall has the insulating sandwich identical with burning portion, its furnace wall is equipped with soot door and inlet pipe, and there is fire grate inside, and vapor chamber is connected with water inlet pipe.Its shortcoming is a complex structure, and gasification efficiency is not good, inconvenient maintenance.
The purpose of this utility model provide a kind of simple and compact for structure, easy to operate, can move continuously, gasification efficiency height, downdraft solid organic castoff vapourizing furnace that cost is low.
The technical solution of the utility model is: a kind of downdraft solid organic castoff vapourizing furnace, comprise body of heater, rotary fire grate (15) and the ash bucket (16) of garden cylindricality, and it is characterized in that body of heater contains roof section, oven dry section, pyrolytic gasification section, cracking section; There is individual top cover (1) the top of roof section, and each section has drying shed (3), pyrolysis vaporizer (6), cracking room (12) corresponding to burner hearth; Connect with bolt by flange (2) between each section; Body of heater is a sandwich structure, and innermost layer is refractory materials (4), and the centre is lagging material (14), and outermost layer is steel plate (9); Pyrolysis vaporizer (6) is in reducing place, is the straight section structure, and skin has a ring-shaped air chamber (7) and inlet pipe (8), and two row's equally distributed tangential admission pipes (5) are arranged on the refractory materials (4); Cracking room (12) is designed to enlarging, with the junction of grey chamber upside many group small-bore venting holes (13) is set bottom in the cracking section, links to each other with vapor pipe (11) with exhaust chest (10); Rotary fire grate (15) is connected with ash bucket (grey chamber) (16) and places the bottom of burner hearth cracking room (12), and cracking section body of heater extends reducing to ash bucket portion, and cooperates water seal (17) with ash bucket (16), and the bottom of cracking room (12) is sealed; Ash bucket (grey chamber) (16) inwall is provided with scraper plate.
In the cracking section is the 3-5 floor with many groups small-bore venting hole (13) that the junction of grey chamber upside is provided with bottom.
The top cover of roof section (1) is opened the back and is used as lighting-up tuyere and charging opening.
Pyrolytic gasification section (6) is provided with annular air compartment (7), inlet pipe (8), tangential admission pipe (5) makes air enter annular air compartment (7) by inlet pipe (8), guarantee that annular air compartment's blast equilibrium, air inlet are even, the air in annular air compartment after the preheating sprays into formation eddy flow stove in by tangential admission pipe (5).The volume of this structure design may command reaction mass so that obtain suitable air equivalent ratio and higher temperature of reaction, makes full use of the waste heat of vapourizing furnace simultaneously, reduces pyrolysis chamber's temperature fluctuation, reduces stove appearance temperature greatly, obtains better pyrolytic reaction result.Rubbish-the solid organic castoff that adds in the stove is at first dried for some time in the oven dry section, after enter pyrolysis vaporizer (6), the material burning of high-temperature zone, pyrolysis vaporizer bottom, the heat heating top material that produces, the pyrolysis under the condition of oxygen deprivation of top material, carbide after the pyrolysis constantly is displaced downwardly to cracking room and burns away, and the gas that pyrolysis produces passes through cracking room (12), venting hole (13), tapered exhaust chest (10), vapor pipe (11) downwards and feeds gas purifying equipment again.Pyrolysis gas is when the cracking room and red-hot carbon-coating generation reduction reaction, produce more CO (carbon monoxide converter) gas, hydrogen and small molecules hydro carbons gas, tar and objectionable impurities in the gas of pyrolysis simultaneously at high temperature can thoroughly be decomposed, significantly reduced gas treating system and handled intensity, thereby the purification system equipment cost is obviously reduced.
Cracking room is designed to enlarging, with the junction of ash bucket (16) upside many group small-bore venting holes (13) are set bottom in the cracking section, link to each other with exhaust chest (10), being beneficial to increases the residence time of pyrolysis gas at red-hot carbon-coating, reduction reaction is carried out fully, improve combustible gas grade and content, reduce cinder content in the gas simultaneously.
The body of heater of downdraft vapourizing furnace is an interlayer, and this structure prevents the corrosion of corrosive gases to body of heater, improves vapourizing furnace work-ing life.
In grey chamber, adopted the structure of rotary fire grate, scraper plate and water seal, can become flexible the incendiary carbon-coating it can fully be burnt, grilled thoroughly and burnout, also can realize downdraft vapourizing furnace continuous discharging slag, made stable the carrying out of generation of combustible gas.
Fig. 1 is the structure iron (sectional view) of downdraft solid organic castoff vapourizing furnace, and Fig. 2 is a vapourizing furnace A-A sectional view, and Fig. 3 is the B-B sectional view. among the figure: 1. top cover, 2. flange, 3. drying shed, 4. refractory materials, 5. tangential admission pipe, 6. pyrolysis vaporizer, 7. ring-shaped air chamber, 8. inlet pipe, 9. steel plate, 10. exhaust chest, 11. vapor pipes, 12. cracking room, 13. venting holes, 14. lagging materials, 15. rotary fire grate, 16. ash buckets, 17. water seals.
