Description

A kind of multi-cavity flue gas burns chamber

Technical field

The utility model relates to rubbish heat treatment technics field, particularly relates to a kind of small-sized small towns refuse pyrolysis gasification burning system and technique thereof.

Background technology

Under the background of new countryside construction, China rural area assumes an entirely new aspect, and the infrastructure in rural area is obviously improved.But be accompanied by peasant's living standard improve time, also occurred many inharmonious parts, production, house refuse are arbitrarily stacked, and cause peasant's Around the house to become soot, near Ye Chengliao refuse depot, farmland house, the road of walking is flooded with motley refuse bag especially.Ministry of Public Health's investigation shows, the house refuse amount of rural area everyone generation every day is at present 0.86 kilogram, the annual house refuse amount in rural area, the whole nation approaches 300,000,000 tons, " rubbish encloses village " forms, this directly threatens peasant's productive life land used, threaten peasant's living environment, threaten the improvement of the public things in village.

In the process of refuse collection, transport, processing etc., need a large amount of funds, because rural residence disperses, have inconvenient traffic, particularly in some mountain areas, the cost that rubbish is processed is higher.And the most village and town finance difficulties of China are unablely born huge garbage disposal expense, be difficult to raise garbage disposal fund.It is low, simple to operate in the urgent need to developing a kind of cost of investment and operating cost that current China processes the realistic problem facing in rural garbage, the technology of garbage disposal of high-efficiency cleaning and equipment.
