Description
Technical field
The utility model belong to solid hazardous waste harmless resource utilization disposal field, and in particular to a kind of rotary kiln with
Plasma gasification cooperates with recycling dangerous waste processing system.
Background technology
In recent years, due to the fast development and the lifting of human living standard of science and technology, the yield of solid waste is increasingly
Many, constituent also becomes increasingly complex.Processing disposal of the various countries to solid waste is also suitable pay attention to.As China integrates in fact
The continuous improvement of power, China turns into the manufacturing nation of maximum in the world.China is as world's factory, and the yield of solid waste is more
It is that can not be ignored.
Because the species of dangerous solid waste (hereinafter referred to as dangerous waste) is various and complicated component, China was in August 1 in 2008
Day announces and formulated《National Hazard waste register》(per there is renewal every year, latest edition is 2016 editions to the register), and dangerous waste is divided
For kind more than 600, totally 47 major class.These materials or with corrosivity, toxicity, inflammability, reactivity or perception, nuclear activity etc.
One or more of hazard properties, need to be managed according to the relevant regulations of strict processing hazardous waste.If dangerous waste is disposed not
When irreversible significant damage can be brought to ecological environment and human health.After contaminated soil and underground water, the mankind are once
Noxious material is taken in by food and water etc. for a long time, the accumulation of human toxin can be made, cause the distortion and canceration of internal cell.
Because dangerous waste is different from the particularity of general industry solid waste, it is considered to its shadow serious to the mankind and environment
Ring, processing of the various countries to dangerous waste be also by special approaches and methods, meanwhile, it is a great valency that the processing of dangerous waste, which is disposed,
The global problem of value.
China's dangerous waste processing disposal starting is late, and technology still needs to improve compared with developed countries, but as China is protected to environment
The attention of shield and support energetically, the dangerous waste processing disposal technology of China just gradually moves to maturity.
The disposal of dangerous waste mainly includes safety burning, sanitary landfills and sea disposal etc..Wherein burning method be dangerous waste most
A kind of maximally effective method in whole disposal technology.Further will be poisonous and hazardous organic in dangerous waste by the burning process of incinerator
Composition is eliminated, and realizes minimizing, wherein the thermal source produced also may be recovered utilization.But it is noted that gas during burning
Discharge, install emission-control equipment, it is to avoid secondary pollution.Sanitary landfills is to carry out the part that can not finally recycle disposal
Solidification landfill, its drawback is the hidden danger for having the pollution for causing underground water.
The dangerous waste burning method disposal of current China is main to use rotary kiln incineration method of disposal, and rotary kiln type incinerator is to burning
Thing changes strong adaptability, and rotary kiln incineration mainly has three kinds of modes：Lime-ash formula is burned, molten slag type is burned, pyrolysis formula is burned.
Wherein lime-ash formula incinerator (800~900 DEG C of in-furnace temperature), dangerous waste is fused by oxidation reaches destruction, rotary kiln
The mainly lime-ash of kiln tail discharge, preferably, because fire box temperature is not high, hazardous waste is resistance to rotary kiln for lime-ash laxity after cooling
The hot, aggressive and oxidisability of fiery material be not strong, therefore, the service life of refractory material is relatively long, inner furnace body " wall built-up "
Phenomenon is not also serious, but ignition temperature is low, can not harmlessness disposing completely for part debirs.
Molten slag type rotary kiln incinerator, which is mainly, handles some stronger dangerous wastes of single, toxicity, and temperature is typically at 1500 DEG C
More than, it is therefore an objective to improve destruction rate.Due to dealing with objects different, complicated component, the type incinerator temperature control is more difficult,
Higher is required to operation.Because molten slag type rotary kiln incinerator fire box temperature is higher, the increase of auxiliary fuel consumption, that brings is most straight
The consequence connect is that rotary kiln refractory material, insulation material fuel consumption, mechanical loss and operation difficulty are higher.
Pyrolysis formula rotary kiln incineration kiln temperature control at 700 DEG C~800 DEG C, due to dangerous waste in rotary kiln pyrolytic gasification
Produce fuel gas to burn into dual firing chamber, fuel consumption can be substantially reduced, low additionally, due to temperature, heat loss is few, exhaust gas volumn
It is that three kinds of handling process are minimum, installed capacity reduction therewith, operating cost is substantially reduced, but it has the disadvantage lime-ash residual quantity
Height, lime-ash burns not thorough.
The problem of for existing during dangerous waste burning disposal, China technical staff expands extensively and abundant research.
