Description
(1) technical field
The present invention relates to a kind of combustible waste material processing unit, in particular to a kind of town and country waste special hydrogen, methane, an oxygen
Change carbon, fuel-gas multiple produces two stage gasification device.
(2) background technique
With socio-economic development, the aggravation of urbanization process, municipal refuse (plastics, waste paper, fallen leaves, sawdust, various packagings
Box, beverage bottle, beverage cartridges, leftover), urban night soil, food garbage, medical waste, biochemical sludge, industrial coal slime, rich in having
Machine matter municipal sewerage system mud, timber etc. have the cultivation excrement for being machined with machine sludge and rural area, cultivation sludge, cultivation ill domestic animal
The various wastes such as corpse, organic matter river silt, straw, waste wood bring larger pollution to environment.
Originally the garbage loading embeading mode used, surrounds each big city gradually by rubbish, pollution atmosphere, polluted underground water,
The especially pollution of plastics and its product.The waste incineration used one after another later, and find new three major issues, first leftover
The landfill leachate of equal generations cannot be handled, the dioxin for generation of then burning, and bring more serious atmosphere pollution, and because
Rubbish water content is larger, and waste incineration is difficult to grill thoroughly, and incineration residue still contains a large amount of pollutants, and direct emission is brought secondary again
Pollution.The direct burning of medical waste, because containing various pathogen, chemical agent etc., it is bigger that processing is not thorough bring harm.
Biomass thermal chemical gasification technology be using biomass as raw material, with oxygen (air, oxygen-enriched property gas or pure oxygen etc.),
Vapor or hydrogen etc. are gasifying agent, convert biomass into the mistake of fuel gas by thermal chemical reaction under the high temperature conditions
Journey.Low-grade solid biomass can be fully converted to high-grade fuel gas by gasification technology, to be widely used in work
The every field of agricultural production, such as central gas supply, for heat and generating power, biomass gasification technology mainly has fixed bed gasification at present
Technology, fluidized gasification technology etc..
The advantages of fluidized-bed gasification furnace is that heat and mass is uniform, and gasification reaction speed is fast, and efficiency of carbon con version is high, and easily amplification is set
Meter；The disadvantage is that content of ashes is high in combustible gas, device structure is complicated, and raw material needs dispersion and fining.
Fluidized gasification technology is directed to the medium and above sizable application, and urgent problem includes:
1. in the gas that gasifies, there are still tar, run gasifying electricity generation and air supply system can not steadily in the long term, can also cause secondary useless
Water pollution.
2. the direct combustion power generation efficiency of fluidized bed only has 15%~25%, gasification-gas turbine combined cycle power plant technology
(IGCC) generating efficiency also can only achieve 35%.Since the waste heat of the thick combustion gas of high temperature and generator tail gas is not used, thermal effect
Rate is low, and generating efficiency is low, and using gasification-gas turbine combined cycle power plant and heat supply coproduction, biomass economy efficiency can be improved
60% or more.
3. needing to develop high gasification efficiency and the gas type gasification furnace without tar, fuel gases calorific value is improved, convenient for using IGCC
Thermoelectricity multiple-supplying.
4. needing the low-calorific-value gas turbine and high efficiency burnt gas that development structure is simple, operating cost is low using BIGCC technology
Purification system.
5. BIGCC technology needs scale development and application, gasification gas cost problem is solved.
The gasification of cities and towns organic solid castoff recirculating fluidized bed, the carbon granules not reacted completely can be returned by material returning device to gasify
Furnace further reacts, and to improve gasification efficiency, improves fuel gases calorific value, fuel gases calorific value can reach 5~8MJ/m3(standard state).Have
The recirculating fluidized bed adaptability to raw material of bed material is strong, and longer stalk can smash to (general 5cm stalk below can be sufficiently anti-
Answer), bed material can be such that the cities and towns organic solid castoff material being added is brought rapidly up, and reduce the gasification reaction time, generate more flammable
Ingredient.Hot combustion gas directly utilizes, can pollution to avoid tar condensing to pipe-line equipment, this will be next step cities and towns organic solid
Waste scale is gasified totally the main direction of development of technology.
City combustiblerefuse, because water content height, calorific value is too low, when town and country combustible waste material be with municipal refuse be it is main when,
Existing gasification technology is difficult to obtain the combustion gas of high heating value, and highest calorific value only has 1200KCal/Nm3, it is difficult to it realizes efficient
Fuel gas generation.
