Description
Technical field
The present invention relates to the burning and drying processing system of castoff burning processing technology field, more particularly to danger wastes
System.
Background technology
With industrial expansion, the hazardous waste of industrial processes discharge is increasing.It is estimated that the whole world is annual
Hazardous waste yield is 3.3 hundred million tons.The serious pollution that is brought due to hazardous waste and potentially seriously affect, in industry prosperity
National Hazard waste has been known as " political waste ", and the public is very sensitive to hazardous waste problem, opposes in the area that oneself is lived
Dangerous waste disposal field is set up, high plus the disposal costs of hazardous waste, some companies are strongly attempted to the undeveloped state of industry
Family and area transfer hazardous waste.
The existing harm of hazardous waste mainly include it is following some：
(1) ecological environment is destroyed.Arbitrarily discharge, storage dangerous waste under the prolonged permeation, diffusion of rainwater underground water,
Meeting polluted-water and soil, reduce the environmental functional grade in area.
(2) human health is influenced.Hazardous waste is by taking in, sucking, skin absorbs, eye contact is poisoned to cause, or drawn
The danger event such as combust, explosion；Long-term hazards include long-term poisoning, carcinogenic, teratogenesis, mutagens caused by repeating to contact etc..
(3) sustainable development is restricted.Hazardous waste do not handle or non-standardized treatment disposal caused by air, water source, soil
The pollution of earth etc. will also become the bottleneck for restricting economic activity.
At present, when handling hazardous waste, burning disposal is mainly carried out using incinerator and rotary kiln.Rotary kiln is danger
The main equipment of incineration of waste, it is lime-ash that the hazardous waste of charging, which can burn remainder, general 800 DEG C or so of in-furnace temperature,
Dangerous waste feed and clinker discharging be it is continuous, rotary kiln turn in during, hazardous waste overturns advance in kiln, to rotary kiln
Afterbody, is advanced into dual firing chamber on gas, and clinker falls through into water seal, cooling and dedusting, by integral type slag remover be carried out come.Mesh
Preceding clinker is carried out packing come after by slag remover, according to national regulation need enter qualified hazardous waste landfill into
Row landfill, 3000 yuan/ton of expense.Obviously, the cost that the hazardous waste clinker after being handled by rotary kiln carries out landfill disposal occupies
Height, and traditional rotary kiln incineration is handled, and energy waste is also serious.
The content of the invention
For the above problem existing for the processing of existing hazardous waste, a kind of processing cost of present invention offer is low, the utilization of resources
The high dangerous waste thing burning and drying integrated processing system of rate.

Transition is connected with taper chopping guide section 3416 between section 3415, and the side face of taper chopping guide section 3416, which has, imports blade
3417, the side face of chopping section 3415 has outer chopping blade 3418, and the inner peripheral surface of chopping sleeve 3412 has and outer chopping blade
The 3418 interior chopping blade 3419 coordinated.In the present invention, import sleeve 3410, conveying sleeve 3411, chopping sleeve 3412 and lead
Go out sleeve 3413 to be separately welded to connect, easy to process, manufacture cost is low.Using outer chopping blade 3418 and interior chopping blade 3419
It is combined, the slag charge of desiccation is shredded.
Preferably, outer chopping blade 3418 is arranged in the side face of chopping section 3415, spiral conveying blade 344 in the shape of a spiral
The hand of spiral it is identical with the hand of spiral of outer chopping blade 3418.Spiral chopping and helical feed are combined, and are improved and are shredded, is defeated
Send efficiency.Also, the screw pitch of outer chopping blade 3418 is smaller than the screw pitch of spiral conveying blade 344, it is therefore intended that, will
Slag charge is extruded to extruding chopping between the outer chopping blade 3418 of rear end, is formed, and chopping result is more preferably.
In the present invention, sleeve 3410, conveying sleeve 3411, chopping sleeve 3412 and the periphery peace for exporting sleeve 3413 are imported
Equipped with integrated casing 3420, the both ends of shell 3420 will import sleeve 3410 and export sleeve 3413 is closed, shell 3420 with
Import between sleeve 3410, conveying sleeve 3411, chopping sleeve 3412 and export sleeve 3413 and form steam jacket 342, shell
3420 one end has steam inlet 3421, and the other end has condensation-water drain 3422.Integrated casing 3420 with it is knockdown
Sleeve 3410, conveying sleeve 3411, chopping sleeve 3412 and the mounting structure for exporting sleeve 3413 are imported, it is easy to assembly.
