A kind of waste incinerator
[technical field]
The invention belongs to a kind of stove, in particular to a kind of waste incinerator.
[background technique]
It is following then be a large amount of house refuse, mesh with the development of society, people's lives quality is become better and better
Preceding usually used trash processing way has following two: one is garbage loading embeading technology is used, however, with urban land
It gradually decreases, people are also in the scheme for finding substitution garbage loading embeading technology;Another way is exactly burning domestic garbage, life rubbish
Rubbish generates a large amount of toxic gas when burning, and house refuse is due to many kinds of, density, the shape of combustible therein
Shape, chemical property, burning special efficacy are all different, therefore many combustibles all cannot sufficiently fire in common burning mode
It burns, and generates a large amount of black smoke and pernicious gas while imperfect combustion, pollute atmosphere and endanger the health of the mankind.
In addition, rubbish, which can generate a large amount of foul smell in open incineration, influences the life of surrounding resident.
In the pernicious gas generated in waste incineration, dioxin system one kind extremely toxic substance, it is ripe that toxicity is equivalent to people
130 times of the extremely toxic substance cyanide known, 900 times of arsenic.The dioxin being discharged into atmospheric environment can be adsorbed on particle
On object, it is deposited to water body and soil, human body is then entered by the enrichment of food chain.Its generation is common due to using
Temperature when mode carries out waste incineration is lower and dioxin under high temperature environment the duration it is too short caused by.

In use, rubbish is poured into the waste incinerator 100 from spout 6, rubbish falls into institute along the spout 6
The inner cylinder 12 of the first furnace body 1 is stated, blower 5 is then opened and supplies, rubbish is lighted using charcoal and gasoline, with gradually increasing for furnace temperature
And the increase of intake air temperature, the moisture in rubbish are gradually evaporated, therefore are not had to add charcoal and gasoline rubbish again and can all be continued
Burning.Solid decomposites a large amount of unburnt gas when first combustion chamber 16 is burnt, these imperfect combustion gas
Body can be again when second combustion chamber 23 encounters second air inlet 122, the air that the third air inlet 222 sprays
Burning.Since the third air inlet 222 is tangentially into second combustion chamber 23, meeting is in second combustion chamber 23
Middle formation vortex, and unburnt gas after entering second combustion chamber 23 at the lower necking 211 to two sides
Diffusion is blocked at fiery intake section 22 described since the influence of the hollow round table 224 is to intermediate reflux and to the first furnace body 1
It flows backwards, and then mixes well with air unburnt gas, improve the efficiency of combustion of unburnt gas.Meanwhile by
Temperature in second combustion chamber 23 reaches 950-1100 DEG C, and the dioxin generated during incineration firing is in second combustion
It burns room 23 to be decomposed, greatly reduces the discharge of dioxin.
Fresh air is preheated in preheating space 34 by smoke exhaust pipe 3 after passing through air inlet 35, and by the blower 5 described in
Induced duct 4 introduces the first combustion chamber 16 and the second combustion chamber 23.
Lime-ash after incineration firing falls the bottom in the first furnace body 1, can be taken out by slag-drip opening 7.
The present invention is used for the first furnace body 1 of burning solid rubbish by being arranged, for decomposing when burning solid incineration firing
Second furnace body 2 of gas out, and be provided with after exhaust portion 3, induced duct 4 and blower 5 preheat fresh air and introduce first
Furnace body 1 and the second furnace body 2 improve the first combustion chamber 16, the intake air temperature of the second combustion chamber 23 and drying and are deposited in the first combustion
Burn room 16 in rubbish, improve the temperature of waste incinerator 100, make the temperature in waste incinerator 100 reach 950 DEG C~
1100 DEG C, reach the decomposition temperature of dioxin, greatly reduces the discharge of dioxin.Meanwhile unburnt gas exists
It spreads at the lower necking 211 to two sides after into second combustion chamber 23, blocks at fiery intake section 22 described by institute
Flowing backwards to intermediate reflux and to the first furnace body 1 for the influence of hollow round table 224 is stated, and then makes unburnt gas and air
It is sufficiently mixed, improves the efficiency of combustion of unburnt gas.
Above description is the detailed description for the present invention preferably possible embodiments, but embodiment is not limited to this hair
Bright patent claim, it is all the present invention suggested by technical spirit under completed same changes or modifications change, should all belong to
In the covered the scope of the patents of the present invention.
