Description
Technical field
The present invention relates to technical field of garbage disposal equipment, especially a kind of cracking for domestic rubbish disposal is gasified
Furnace.
Background technique
There are many city house refuse treatment method, mainly there is compost, burning, sanitary landfills, classification recycling and integrated treatment
Deng.In recent years, domestic garbage comprehensive processing has caused more and more to pay attention to, but China is most widely used so far is still
First three methods.
1, compost treatment:
Compost is to make rubbish, the organic matter in excrement, under microbial action, carry out biochemical reaction, eventually form one kind
The substance of similar humus soil, can be used as fertilizer or improvement soil, and the key of compost is that providing one kind makes to biology actively
The environment of growth makes up to stabilization to accelerate the decomposable process of bacterium.Compost is mainly by the nutrient in waste, temperature, temperature
The control of the factors such as degree, pH value.According to compost principle, it is slower that anaerobe decomposition growth can be divided into, therefore be not mostly used.Aerobic point
Solution preocess can generate high temperature simultaneously, to kill viral worm's ovum, bacterium etc., China mainly uses aerobic decomposition method.Composting technology
Technics comparing it is simple, be suitable for the higher garbage disposal of the perishable content of organic matter.Resource benefit can be carried out to the part in rubbish
With.
2, sanitary landfill method:
Sanitary landfill method refers to that, using bottom antiseepage, rubbish layering landfill, top layer overlying soil after compacting makes rubbish in anaerobism item
Part issues alcohol, and to reach harmless waste disposal method, because its method is simple, investment-saving can handle the rubbish of all kinds,
So this method is continued to use in countries in the world extensively.From uncontrolled landfill, sanitary landfills is developed to, including filtration cycle landfill,
Compressed garbage landfill, shredding refuse landfill etc..
3, incineration method:
Incineration method is to burn rubbish at high temperature, and waste heat is effectively utilised to generate electricity.In-furnace temperature when due to waste incineration
It must assure that the pathogen at 850 DEG C or more, in rubbish is thoroughly killed, achieve the purpose that from face innoxious.After waste incineration,
Lime-ash only accounts for the 5 ~ 10% of original volume, has accomplished minimizing well, but incineration method investment is big, the occupied fund period is long；Burning pair
The calorific value of rubbish has certain requirement, generally cannot be below 5000KJ/kg, limits its application range.It is produced in burning process
The reasons such as raw dioxin problem, greenhouse gases scheduled production cause treatment facility nearby residents opposition person in the majority, cause addressing difficult, ring
Difficult, construction hardly possible is commented, difficult situation is run.
Currently, generally comprising for the incinerator of incineration method and being equipped with charging including the top with furnace body, furnace body
Mouthful, bottom end is equipped with ash hopper, and carrying and Pintsch process house refuse are equipped between feed hopper and ash hopper in furnace body
Fire grate, on furnace body correspond to fire grate top be equipped with igniter；When garbage disposal, house refuse is inputted from feed hopper
It onto fire grate, lights a fire to it, makes it under conditions of high temperature and sufficient oxygen supply, carry out Pintsch process reaction and generate gaseous inert gas object
Reach that rapid volume reduction, thorough high temperature is innoxious and resource is sharp again with inorganic noncombustibles to form stable solid residue
Purpose, however, this life refuse high temperature cracking reaction furnace ignition temperature only up to reach 850 DEG C, and waste incineration
Process can generate dioxin, and under 850 DEG C of ignition temperature, indivisible dioxin can generate pollution.
Summary of the invention
The present invention provides a kind of cracking gasification furnace, it can solve, and existing cracking gasification furnace ignition temperature is low, pernicious gas
Indivisible problem.
To solve the above-mentioned problems, the technical scheme adopted by the invention is that: it includes having feed inlet and ash hopper
Furnace body, the furnace body is interior to be equipped with combustion chamber, is equipped between the feed inlet and the ash hopper in the combustion chamber
Fire grate is surrounded by sheath room outside the combustion chamber, and the top outside lower part and the ash hopper outside the combustion chamber, which is surrounded with, to be helped
Fire room；The gas outlet communicated with the combustion-supporting chamber is equipped on the wall of the combustion chamber lower part；It is set on the combustion-supporting chamber outer wall
There is air intake；The combustion chamber top is communicated with fuel gas conduit.
In above-mentioned technical proposal, more specific technical solution may also is that the fire grate is divided into upper fire-grating and lower fire grating, institute
State upper fire-grating ash-falling hole hole be greater than the lower fire grating ash-falling hole hole, the combustion-supporting chamber partially surround the lower fire grating with
Outside the ash hopper upper section between the upper fire-grating；Outside the lower fire grating to the ash hopper lower section between the ash hopper bottom end
Equipped with gas chamber, the ash hopper lower section outer wall wall is equipped with air inlet, is connected with air inlet pipe on the gas chamber outer wall.
Further: the ash hopper bottom end is horizontal ash discharge blender, and ash discharge pipeline is housed in the blender bottom end；Institute
Blender is stated with a circular fixed ring, has a shaft to be laterally interspersed in the annular shape from the annular shape fixed ring center line
On the two sides of fixed ring, multi-disc stirring blade is provided in the section that the shaft is located in circular fixed ring.
It is further: the thermocouple for detecting temperature is equipped in the combustion chamber and in fuel gas conduit.
Further: the furnace body outer wall is equipped with the observation for observing fuel in combustion chamber pyrolytic gasification situation
Window, the fuel gas conduit top are equipped with temperature control observation window；It is set near the fuel gas inlet of the combustion chamber top and the fuel gas conduit
There is partition.
It is further:: the furnace body is set on the support frame.
Further: the air intake is connect with tracheae, which connect with air blower.
By adopting the above-described technical solution, compared with prior art, the present invention has the following advantages:
1, due to combustion chamber outside lower part and the top of ash hopper be surrounded with combustion-supporting chamber, be equipped with and help on the wall of combustion chamber lower part
The gas outlet that room communicates is fired, the fuel gas generated in combustion chamber has part to enter in combustion-supporting chamber, gives burning greenhouse heating, makes
It is more abundant that combustion chamber internal combustion hardening cracks solution, temperature can be made to reach 1000 DEG C~1400 DEG C, the dioxin generated when by low-temperature burning is complete
Portion's cracking is fallen, and the generation of pernicious gas is avoided.
2, since fire grate is divided into upper fire-grating and lower fire grating, the ash-falling hole hole of upper fire-grating is greater than the ash-falling hole hole of lower fire grating, helps
Combustion room has outside the ash hopper upper section partially surrounded between lower fire grating and upper fire-grating, big without cracking complete lime-ash from upper furnace
Lower fire grating is fallen in round, ash hopper upper section heats in the combustion-supporting chamber outside ash hopper upper section, and making not burn cracks complete ash
Slag burns away cracking, avoids unburned complete lime-ash and forms block, results in blockage.
3, there is ash discharge blender since ash hopper bottom end is horizontal, ash can be fallen from the blade gaps of blender, if ash row
It compensates out, can be rotated the shaft of blender, shaft band movable vane piece circumferentially rotates up and down, ash is scraped.
