Description

The domestic garbage gasification incinerator
Technical field
The utility model relates to combustion furnace, particularly a kind of domestic garbage gasification incinerator.
Background technology
At present, solving at home and abroad that the consumer waste incineration problem mainly adopts is grate-type incinerator, fluidized bed incinerator and pyrolysis gasification furnace.The grate-type incinerator is the equipment of technical maturity with a long history, is the widely used type of furnace of American-European countries.From the angle of Combustion, the combustion system of grate-type incinerator belongs to layer combustion, is applicable to stable components, calorific value height, the fuel that moisture is lower.The categorized consumer waste of American-European developed country is handled well, belongs to that calorific value is higher, stable components, fuel that moisture is lower, adapts to the burning of grate incinerator, and is stable, but still needs oil gas combustion-supporting, the operating cost height.And China's house refuse has moisture height, calorific value is low, complicated component is changeable characteristics, all run into the problem of " not acclimatized " from the grate-type incinerator of early stage introduction, after necessary technology and technological transformation take a favorable turn slightly, but it is combustion-supporting to add oil gas, fire grate quality requirement height, fire grate is rotatable parts, and the more maintenance of part is complicated, thereby the high phenomenon of operating cost still exists.CFBB begins to be used for city garbage burning by Japan before 20 years, needs to add the combustion-supporting and quartz sand auxiliary material accumulation of heat of coal.The similar coal dust fluidisation of its combustion system combustion technology, but owing to be subjected to the restriction of property conditions such as rubbish size hardness, fluidized state is wayward.Circulating fluidized bed incinerator structure more complicated, as when adopting the High Temperature Gas solid separator, its size is huge, cost is higher, the flow resistance of material circulating system is big in the whole stove, and the power consumption of boiler unit operation is increased, and burner hearth internal heating surface and flame retardant coating, separator inwall are subjected to material and wash away, have wearing and tearing in various degree, need periodic inspection, replacing.Incinerator for thermal decomposition is generally vertical structure, and horizontal type structure adopts segmented, and its burning mode is a fractional combustion, only is applicable to small-sized consumer waste incineration, still needs oil gas combustion-supporting, its operating cost height.
The utility model content
For solving the problems referred to above that existing consumer waste incineration equipment exists, the utility model provide a kind of ratio of combustion fully, the thermal efficiency is high, pollution is little, good to Chinese house refuse adaptability, and safe and reliable, small investment, without fuel oil with mix coal, domestic garbage gasification incinerator rational in infrastructure.
Above-mentioned task realizes by this way: a kind of domestic garbage gasification incinerator, include horizontal body of heater, furnace rake, dust collection chamber, fire door, exhaust outlet, charging aperture, air inlet and air blast, it is characterized in that: also be provided with a vertical gasification furnace, be provided with a partition wall in the lower furnace portion of described horizontal body of heater and will be separated into waste incineration chamber and refuse gasification chamber before and after the burner hearth, top, two Room is communicated with, the furnace rake of refuse gasification chamber is low early and high after to be obliquely installed, in charging aperture, be provided with the material feeding box of a strap brake door, rear end, refuse gasification chamber is bellows, these bellows are connected with air blast, several air inlets are evenly opened on the inwall of bellows, described vertical gasification furnace is by body of heater, burner hearth, charge door, furnace rake and dust collection chamber form, dust collection chamber is formed by ring-type bellows, bellows are connected with air blast, evenly have several air inlets in the bellows upper inside wall, laterally be provided with an appendix that is connected with horizontal chamber furnace (oven) refuse gasification chamber at the body of heater middle part.
This incinerator is work like this: time spent elder generation of elder generation allows it light from the waste material of the past less easy burning of a certain amount of volume of the indoor adding of waste incineration of observation door of waste incineration chamber, makes the waste incineration chamber be in the naked light state; The waste materials that meanwhile also add some easy burnings toward furnace rake from the fire door of refuse gasification chamber, and light these materials, by artificial or mechanical conveying equipment house refuse the like waste material is sent into material feeding box from charging aperture subsequently, pushing gate open falls in the vaporizer. and since the biomass castoff material be deposited in refuse gasification indoor be quickly can not get clean-burning, but chemical reaction just takes place after being heated, discharging unburned gasification gas. regulate the air quantity that enter refuse gasification chamber by the control air blast this moment, make unburned like this gasification gas deliver to the waste incineration chamber can not get crossing partition wall under the clean-burning situation, run into naked light fully burning immediately, producing high-temperature flue gas directly discharges from exhaust outlet, deliver to waste heat boiler or other needs the equipment of heat supply. when horizontal incinerator operation, the combustible material of bulk can be added in the vertical gasification furnace, light these materials by fire door, and make it under anaerobic conditions heat the generation chemical reaction, discharge unburned gasification gas, the refuse gasification that is passed to horizontal chamber furnace (oven) by appendix is indoor, intensification and the gasification efficiency that improves horizontal chamber furnace (oven) refuse gasification chamber house refuse all there is tangible effect, improves the processing of house refuse greatly.
The gate of the material feeding box of this incinerator is carried out the one open-one close state when incinerator moves, to guarantee the loss that can not leak of heat in the refuse gasification.From structure of the present utility model and operation principle thereof as can be known, this domestic garbage gasification incinerator has been compared following advantage with existing incinerator:
1. the utility model reasonably is divided into burner hearth two chambers of refuse gasification and waste incineration, make a large amount of house refuses at a large amount of unburned gasification gas of the indoor generation of refuse gasification, fully burn in the waste incineration chamber that is transported to naked light then, make the hot gas of output not have unburnt gas basically, improve the thermal efficiency greatly.
2. the utility model adopts vertical gasification furnace next combustion-supporting, its effect as existing grate-type incinerator need oil gas or coal combustion-supporting the same, but owing to not needing fuel oil and oozing coal, can reduce operating cost significantly, realize energy-saving and emission-reduction, and improved the thermal efficiency of whole stove.
3. in the running of horizontal incinerator, under the gasification gas effect that the air-supply and the vertical gasification furnace of bellows are sent to, realize stratified carburation and burning from the rubbish nature that material feeding box enters in the stove according to lumpiness size and deadweight, the gas that makes rubbish material and output is in different temperatures, different combustion layers, combustion distance and combustion Cheng Jinhang pyrolytic gasification and burning, compare with other incinerator more trickle, more reasonable, more science is carried out preheating, gasification and burning to rubbish.
4. the utility model is better to house refuse adaptability, only incombustible separating substances need be come and just can.
Relatively simple for structure, the small investment of the utility model, implement easily, and safe in utilization, simple to operate, easy to utilize.
