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 have a strong impact on, in industry prosperity
National Hazard waste has been referred to 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 influenceed.Hazardous waste is by taking in, sucking, skin absorbs, eye contact is poisoned to cause, or drawn
The dangerous event such as combust, blast；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 turn into 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, needs to enter into qualified hazardous waste landfill according to national regulation
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.
