Description
Technical field
The utility model is related to rural garbage burning disposals more particularly to a kind of rural garbage innoxious, minimizing and money
The incinerator in source.
Background technology
Rural garbage can be divided into liveliness proof rubbish and productivity rubbish two major classes.Wherein liveliness proof rubbish refers to villager in day
Often generated solid refuse in life or when providing service for daily life.And it includes that kind grows industry rubbish that productivity rubbish, which is,
(such as stalk, mulch, agriculture chemical packaging), aquaculture rubbish (excrement of such as domestic poultry), industrial refuse, medical waste
And building waste.By continuing to develop, the yield of rural garbage is also constantly improving in China.At the same time, different regions agriculture
There is also larger differences for the source of village's rubbish and ingredient composition.
The processing method that China rural garbage mainly uses at present for：Landfill, burning and compost.And in the mistake of waste incineration
It is harmful to environment and human body to will produce a large amount of flue dust, nitrogen oxides, oxysulfide, carbon monoxide, bioxin etc. by Cheng Zhong
Substance.
Wherein , bioxin is a kind of colorless and odorless, the serious liposoluble substance of toxicity, can damage a variety of organs of human body and
System.It mainly pollutes air, soil, water body, and then endangers animal, plant and human body.Due to the biological concentration of bioxin
Effect it is very strong, so can step by step be accumulated with food chain, the content in advanced organism is higher, thus the mankind by
The degree of harm is maximum.And mankind itself can not decompose bioxin, once intake, is just not easy to be discharged.Studies have shown that human body is taken the photograph
Even entering in the case of very micro, taken long-term can also cause the disease of cancer, skin disease, liver and kidney disease etc..
And the major advantage that rubbish fire grate burns has：Technology is more mature, equipment year run time up to 8000h or more,
Garbage disposal cost is relatively low, can be widely used in all kinds of rubbish, and the flying dust generated is less.But the disadvantage is that：It burns
Furnace temperature passes through the temperature range (360~820 DEG C) of bioxin production when stove is opened and is deactivated, incomplete in the case that controlling
Easy to produce bioxin.
But since rural garbage has the characteristics that yield is big, so waste incineration is more suitable for now compared to other two kinds
Rural condition.Therefore, it is necessary to optimized to Refuse Incineration Process, a Feasible degree height, easy to operate, close is designed
The garbage incineration method of zero-emission.
Invention content
It is harmless to provide a kind of rural garbage for the shortcomings that the purpose of the utility model is to overcome the above-mentioned prior arts and deficiency
Change, the incinerator of minimizing and recycling.
The utility model is achieved through the following technical solutions：
