Description
Technical field
The present invention relates to a kind of solid waste innocent treatment equipment, particularly a kind of small evaporator incinerator, the various solid waste that factory or general family discharge can be become gas by Thorough combustion and incinerate.
Background technology
Along with China's rapid development of economy, the speed of urbanization process is constantly accelerated, and living standards of the people improve constantly, and the generation of domestic waste and plant wastes constantly increases, pollution problem is day by day serious, and this is one of obstruction having become China's sustainable economic development also.In the past between more than ten years, family of China and waste from a factory generation average growth rate are quickly, the environment pollution control of China to city and waste from a factory is compared with Air Pollution Control with water pollution control, start late, process disposal facility wretched insufficiency, mostly standard is lower for built process disposal facility.For solving the problem of China's noxious waste pollution environment, need to build a large amount of offal treatment disposal facility.Due to burning method can realize that solid waste is innoxious the soonest, to greatest extent, stabilisation, minimizing, resource, become one of main method of solid waste process at present in industrially developed country.
External incineration treatment of garbage technology and equipment are comparatively ripe, and the various type of furnace commercially bases oneself upon part.The main flow type of furnace comprises: mechanical grate incinerator, rotary kiln incinerator, fluidized bed incinerator and emerging incinerator for thermal decomposition etc.As third generation technology of garbage disposal, pyrolysis gasification furnace relies on its congenital many advantages possessed, and has presented the trend replacing the conventional types of furnaces such as grate furnace and fluid bed furnace in developed country.
When burning the discarded object containing solid carbon hydrogen compound, the burning of less than 800 DEG C can produce bioxin, and this becomes a great residue problem.In order to solve bioxin, just must be passable with the high-temperature heating more than 2 seconds of more than 800 DEG C.In particular, general need 1000 DEG C even preferably more than the high-temperature heating of 1250 DEG C at least more than just can decomposing completely by Shi bioxin for 2 seconds.But, this can only by gasify and the large-scale CIU of complexity that combustion enginnering is separated just can accomplish, such as existing a kind of environment-friendly and energy-efficient garbage pyrolysis gasification incinerator, the key point of this refuse gasification incinerator is in burning process, rubbish carries out thermal cracking in the first combustion chamber, toxic gas generation can be controlled in very little scope, complete high-temperature oxydation through the second combustion chamber again to burn completely, therefore the flue gas of its discharge can reach strict discharge standard, this combustion furnace sets up independently two combustion chambers separately, its volume is larger, structure is comparatively complicated, and not easy operation control.But the fairly simple small incinerator of existing structure can't reach the target of decomposing bioxin completely with continual and steady high temperature, a kind of structure is simple, hold easy operation control, and research and development is needed badly by the small evaporator incinerator that can decompose bioxin completely.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of small evaporator incinerator, mainly solve the simple small evaporator incinerator of existing structure can not decompose bioxin technical problem with continuous high temperature, and can burning velocity easily in control combustion stove or burning scale.
