Stove is placed on flammable useless solid and combustible exhaust gas in one mixed combustion furnace and burnt, and investment is big, operational control very flexible, flammable useless
Gu burning and combustible exhaust gas burning are unable to independent operating, follow-up supporting dedusting, desulphurization and denitration imperfection, fume emission is not up to standard.
The content of the invention
The problem of present invention exists for current discarded object (flammable useless solid and combustible exhaust gas) burning processing, there is provided Yi Zhongjie
Can type waste combustion waste-heat recovery device.Energy-saving waste combustion waste-heat recovery device is mainly by useless solid combustion furnace, waste gas
Combustion furnace, waste heat boiler, electrostatic fabric filter, air-introduced machine, desulfuring and denitrifying apparatus, chimney are formed, it is characterized in that flammable useless solid and can
Combustion waste gas burns in useless solid combustion furnace and waste gas burning stove respectively, give up solid combustion furnace and waste gas burning stove can with isolated operation,
Operational control is flexible, and no matter useless solid combustion furnace or waste gas burning stove break down, and system can continue to run with；Waste heat boiler enters
Row waste heat recovery produces steam and uses for production, life or taken off for steam turbine power generation, subsequent configuration electrostatic fabric filter and desulfurization
Nitre device ensures flue gas qualified discharge.
The structure and operation principle of energy-saving waste combustion waste-heat recovery device be：It is flammable useless solid mixed by crushing and screening
Close, be configured to calorific value be 2000~3000Kcal/kg, granularity for≤8mm fuel after, through flammable useless solid bunker, belt feeding
Machine, batcher, which enter useless solid combustion furnace bottom, to be carried out mixing fluidizing with the air come by air-distribution device and is fired at 1000 DEG C or so
Burn, mixed flue gas goes upward to ciculation fluidized separation in the middle part of useless solid combustion furnace, and high-temperature flue gas enters waste gas by connecting flue tangent line
Combustion furnace, the fine ash carried secretly by cyclone cylinder cyclonic separation；Low calorific value waste gas and high heating value waste gas pass through low calorific value waste gas respectively
Burner and high heating value gas flare are sent into waste gas burning furnace roof portion, with the high temperature cigarette from useless solid 1000 DEG C or so of combustion furnace
Gas mixes and is ignited fully burning, and high-temperature flue gas leaves waste gas burning stove into waste heat boiler and taking off from desalted water pipe network
Salt solution progress heat exchange, produce steam and used or for steam turbine power generation, flue gas cool-down for production, life into steam pipe system
Further heated into stove air to 200 DEG C into air preheater, the flue gas that temperature is down to less than 150 DEG C is removed by electrostatic fabric filter
Dirt, flue gas is sent into desulfuring and denitrifying apparatus scrubbing CO_2 and nitrogen oxides, clean flue gas by air-introduced machine pressurization after dedusting
Pass through chimney qualified discharge (flue dust ＜ 20mg/m3, sulfur dioxide ＜ 50mg/m3, nitrogen oxides ＜ 100mg/m3).Useless solid burning
After caused clinker (phosphorus content≤2%) and ash are sent by lag cooler cooling and Slag Scraping Device discharge respectively in stove and waste gas burning stove
Continuous producer recycles.
It is durable the beneficial effects of the invention are as follows stabilized structure, investment reduction, energy-efficient, safety and environmental protection is easy to operate.
