Description

The domestic waste gasification furnace
The utility model relates to a kind of equipment of handling domestic waste, particularly a kind of gasification furnace that can utilize combustion gas that incineration firing is produced.
The processing of traditional cities rubbish mainly contains landfill method and open burning method, there is the problem of polluted underground water and atmosphere pollution in these two kinds of methods, so the disposal of refuse of combustion gasification stove is all adopted in many cities gradually, garbage disposal can be fallen on the one hand, obtain combustion gas on the other hand for generating, boiler or civilian can also obtain can be used as the ashes of agricultural fertilizer, and refuse is fully utilized.At present relevant documents and materials disclose some garbage gasification burners, its basic structure is by garbage inlet, the combustion chamber, vaporizer, parts such as escape pipe and air exhauster constitute, because rubbish composition complexity, existing organic matter is organic/inorganic substance also, so need carrying out careful sorting in advance, a lot of garbage disposal plants just rubbish is dropped into the gasification of stove internal combustion, in the design of stove, the quality and the vaporizer of gasification, the structure of combustion chamber has much relations, can be because combustion gasification is not only with incineration firing, also need to make rubbish to produce combustion gas, not enough as stove internal combustion temperature, combustion gas can't produce, even can stop working, temperature is too high, only produce carbon dioxide and water again, also can not get combustion gas, at present a lot of domestic refuse gasification boilers part that structurally all comes with some shortcomings, its design is adopted and the similar structure of traditional water coal gas Gas-making Furnace mostly, as Chinese patent ZL98226675 " municipal refuse gain of heat gasification furnace ", the structure of this patent incineration firing gasification stove is by fire door, burner hearth, in heating up in a steamer layer, oxide layer, reducing zone, ash bed, deslagging hinge dragon, parts such as exhaust outlet constitute, its exhaust outlet is located at lower furnace, burner hearth and deslagging adopt similar water coal gas Gas-making Furnace structure, the characteristics of the stove of this structure are the composition height that needs combustible, just can effectively produce combustion gas, so this patent is except will more conscientiously screening rubbish, particularly remove outside the inorganic composition as far as possible, the rubbish of going into stove also must add an amount of solid coal dust, and just can go into stove burning with the mechanical presses moulding, so just increased the garbage disposal cost, the city that lacks for fire coal particularly will be promoted and had certain degree of difficulty.
The purpose of this utility model provides a kind of simple in equipment, does not need meticulous pre-screening rubbish, also need not add fire coal and with the rubbish extrusion modling, be fit to gasification furnace big-and-middle, the small city garbage disposal.
The technical solution of the utility model is: the domestic waste gasification furnace comprises charging aperture, the combustion chamber, vaporizer, gas outlet tube, parts such as air-introduced machine, concrete structure is that this gasification furnace divides charging aperture, the low temperature drying chamber, the Rotary drying chamber, vaporizer, the gas outlet pipe, cap chamber, several parts of furnace bottom, wherein feed hopper is located at stove top, feed hopper has manhole cover, and the dilatory door of sealing is housed, top, low temperature drying chamber below the feed hopper is provided with gas outlet tube and explosionproof hole, it under the low temperature drying chamber Rotary drying chamber, it is placed in the circumferential wall of vaporizer top by the bearing block of band oil sealing, the upper end also is connected with the low temperature drying chamber by oil sealing, be that whole Rotary drying chamber provides power to drive the positive and negative rotation of 360 ° in work with gear or friction wheel by motor, the Rotary drying chamber also is provided with liftable driving lever, driving lever also carries out the circumference rotation thereupon when Rotary drying chamber circumference rotates, the rubbish that is bonded on the wall is scraped, make it burning evenly, vaporizer is provided with and stirs cinder hole and backflow spray bar, the vaporizer below is cap chamber (combustion chamber), cap chamber is provided with the backflow Gas Pipe, its below is provided with cap chamber front, gain of heat combustion chamber and has fire door, slag tap rake and suspension grate are installed below the cap chamber, furnace bottom is the pond, the effect in pond is with the slag cooling and produces water vapour, regulate the temperature of cap chamber, and the hydrogen and the carbon monoxide of generation cracking, for making Rotary drying chamber smooth rotation and whole shaft firm, pillar is equipped with on (the bearing block below of Rotary drying chamber) and top, low temperature drying chamber on vaporizer top.
The operation principle and the process of the utility model refuse gasification boiler are as follows:
To make the rubbish of sorting (selecting the shaft and the block of overlength, super large) slightly and deliver to top of gasification furnace, behind the hopper of packing into, open the dilatory door of sealing, rubbish is entered in the stove, under the cap chamber action of high temperature, carry out gasification reaction by elevator.Rubbish thickness in stove approximately remains on the height of low temperature drying chamber 2/3, under the effect of air exhauster negative pressure, high-temperature gas rises by upper strata rubbish, take away the moisture content in the rubbish, gas after the cooling is extracted out by the outlet on stove top with water vapour, through cooling, after the purified treatment, combustion gas and moisture content, tar separation, the tar of separating refluxes and sprays into the help burning of cap chamber top, combustion chambers burn is returned in the part combustion gas, is the gain of heat in the stove, in the stove required air and water vapour under last suction effect by the furnace bottom pond with stir cinder hole and enter cap chamber, oxidation reaction takes place, and the heat that the combustion chamber produced simultaneously also is inhaled into the cap chamber gain of heat.
The utility model has the advantages that:
1. house refuse is except that volume the excessive or length overlength, but substantially without the sorting direct gasification;
2. being in operation does not need to add in addition coal, fuel oil or other gain of heat fuel;
3. disposal of refuse amount is big, and processing speed is fast, and secondary pollution is few;
4. be less than 40% as long as contain inorganic composition in the rubbish, no matter house refuse or industrial refuse can both carry out gasification process mostly effectively;
5. the disposal field floor space is little, and processing links is few, and expense is low, wide adaptability;
6. equipment is simple, reduced investment, and cost is low, and a large amount of combustion gas of output can be used as the high-quality industrial energy, for economic benefit has been created in treatment of urban garbage.
Below in conjunction with accompanying drawing enforcement structure of the present utility model is described:
