Description
Technical field
The room burner that the utility model is related to discarded object burns disposal technology altogether, more particularly to danger is put in a kind of coexistence of room burner
Dangerous waste incineration system.
Background technology
According to China Statistical Yearbook data, national industrial solid wastes yield is 325620.02 ten thousand tons within 2014, wherein
Hazardous waste yield is 3633.52 ten thousand tons, and volume of comprehensive utilization, disposal amount, storage capacity are respectively 2061.80 ten thousand tons, 929.02
Ten thousand tons, 690.62 ten thousand tons, joint disposal utilization rate is 82.3%.Generally, the production of China's industrial solid waste and dangerous waste
Cumulative year after year is measured, and corresponding disposing capacity is limited, causes joint disposal utilization rate to be in reduced levels.
At present, the disposal technology of hazardous waste is existing nearly hundred kinds in the world.In developed country, due to land resource limitation and
Environmental regulation requirement, burning method turns into widest Waste disposal mode.At present, the developed country such as European Union, the U.S. and Japan has been
Through extensively using room burner coexistence put sewage sludge and solid recovery fuel (SRF), can not only realize waste minimizing and
It is innoxious, and can at utmost reclaim the energy of waste and substitute part fossil fuel.From the eighties in last century, with the U.S.
EPA puts the research and application of hazardous waste technology for the western developed country application room combusting boiler coexistence of representative, but
The hazardous waste coexistence of China puts incineration technology and is still in the starting stage.China's station boiler is based on the burner of room, room burner tool
There is disposal amount big, environmentally friendly corollary equipment is complete, security reliability is high, the advantages of load adaptability is strong, the high temperature in its stove is to burn
Burn coexistence and put hazardous waste there is provided possible.Therefore, the incinerator that hazardous waste is put in a kind of rational room burner coexistence is designed
It is necessary.
The content of the invention
The purpose of this utility model be overcome room burner incinerator can only combustion of fossil fuels (such as coal) and solid it is useless
The not enough of gurry (such as sewage sludge) puts hazardous waste burn system there is provided a kind of coexistence of room burner.
Hazardous waste burn system is put in room burner coexistence includes room burner incinerator and feeding system；Room burner burns dress
Put including room burner burner hearth, burner, atomising burner, burn air port, water-cooling wall, back-end ductwork, slag-draining device；Lower furnace portion
It is provided with burner, atomising burner and burns air port, the upper furnace wall paper of burner hearth is equipped with water-cooling wall and is connected with back-end ductwork,
Burner hearth bottom is provided with slag-draining device；Feeding system includes coal bunker, solid-state hazardous waste feed bin, feeder, coal pulverizer, First air
Machine, overfire air fan, liquid hazardous waste batch can, liquid hazardous waste feed pump, feeding-in solid body mouth, liquid inlet opening；Coal bunker and
Solid-state hazardous waste feed bin is connected by feeder with the charging aperture of coal pulverizer, the air inlet phase of primary air fan and coal pulverizer
Even, the discharging opening of coal pulverizer is connected with feeding-in solid body mouthful, and Secondary Air is combustion-supporting by overfire air fan feeding feeding-in solid body mouthful, and liquid is dangerous
Waste batch can is connected by liquid hazardous waste feed pump with liquid inlet opening.
The utility model realizes the room burner coexistence that liquid and solid-state hazardous waste feed respectively and puts dangerous waste incineration
Device, solve room burner incinerator can only combustion of fossil fuels (such as coal) and solid waste (such as sewage sludge) no
Foot, the innoxious and energy for realizing hazardous waste is recycled, liquid hazardous waste charging gear and solid-state hazardous waste feed
Device is independently run, and low heat value liquid hazardous waste also can not can simultaneously be run during independent burning, both ensure that room burner
The stable operation of hazardous waste burn system is put in coexistence, also ensure that the instant incineration disposal of solid-state and liquid hazardous waste.
