Compared with prior art, the present invention has the advantages that：
（1）Refuse pyrolysis gasification technology brake specific exhaust emission is up to standard, non-secondary pollution
Waste incineration and generating electricity is the single treatment pattern directly burned to rubbish in the case of addition coal and fuel oil, because
Harmful substance burning not thoroughly, decompose incomplete, be directly discharged in air to be formed secondary pollution with flue gas, and due to stressing pair
The utilization of heat energy power-generating, furnace temperature is difficult stable more than 850 degree, causes bioxin yield to increase；In addition, fermentation or drying
The percolate of high number is also produced Deng pretreatment, it accounts for the 33% of rubbish gross weight.Therefore, garbage incineration technology pollutes
Larger, three-protection design difficulty is big.
The present invention is by technology effective integrations such as pyrolytic gasification, combustible gas oxygen-enriched combusting and second-time burnings, by controlling oxygen supply
Amount, temperature, realize that the pollutant yield such as bioxin is substantially reduced；By fuel gas in oxygen-enriched combusting layer and dual firing chamber

Hereinafter, prevent decomposed polychlorinated biphenyl material in CuCl2, C atoms catalysis under once again He Cheng bioxin , dioxin emissions it is dense
Degree is far below《Consumer waste incineration contamination control standard》（GB 18485-2014）, better than EU criteria, this is the present invention and rubbish
The maximum difference that rubbish is directly burned.In addition, flue gas is through cyclone dust removal, chilling heat exchange, dedusting, washing（Alkali lye）Dust-removal and desulfurizing, work
After property charcoal adsorption treatment, other pollutants are below relevant national standard.
（2）Without addition auxiliary dyestuff, operating cost is low
In addition to needing extraneous auxiliary fuel when being reruned after lighting a fire or overhauling first, this equipment is during stable operation without again
Any auxiliary fuel is added, only relying on rubbish itself calorific value can continually and steadily run.This equipment is in stable operation, because of oxygen supply
Measure small, pollutant yield few, reduce further power consumption, water consume and the fume treatment cost of operation.Use refuse pyrolysis gas
Change processing equipment and technology, direct processing cost is only 1/5th of conventional art, even lower.
（3）Without sorting, simple to operate, garbage disposal scope is wide
Waste incineration method processing rubbish technology comes from American-European and Japan, but the refuse classification specification of these areas and country, presents
Rubbish unicity, high heating value, it is drier the characteristics of.And the municipal refuse of China particularly central and west regions is generally in a mess, contain
Water rate is also very high, and this just makes import equipment and counterfeit devices Chinese " not acclimatized ", and the rubbish built up is invested in part with much money
Just operation just stops production rubbish incineration plant.
The present invention has high-adaptability, and rubbish is without stacking fermentation diafiltration, and without any classification, the rubbish of mixed collection is straight
Stove processing is accessed, the characteristics of China's domestic waste complicated component, inconvenience are sorted, moisture content is high, calorific capacity is low is especially suitable for.
Refuse pyrolysis gasification technology than directly burn more adapt to the compound of China, low heat value, high-moisture percentage garbage disposal.
