Description
Technical field
A kind of flue gas of refuse burning be the utility model is related to without white cigarette environment protection emission high-level cleaner.
Background technology
Incineration flue gas of household garbage purification technique has dry method, wet method, semidry method.Because dry-process deacidification is less efficient, wet method needs
Waste water is handled, China's conventional garbage incineration flue gas uses semidry method more, i.e. spray dry absorbingatreatingastep adds activated carbon to inhale
Additional sack cleaner combination purification technique.During work, the flue gas after heat is absorbed by waste heat boiler and initially enters spray absorber
Reaction tower, meanwhile, high-speed sprayer sprays into vaporific Ca (OH) into reaction tower2（Lime slurry）, vaporific Ca (OH)2Thin
Grain and HCl, HF and SO in flue gas2React, reacted flue gas, which enters after deduster removes particulate matter, to be discharged into greatly
Gas, the product and flying dust of reaction are discharged from reactor ash port or deduster ash port together.
The weak point of existing this flue gas of refuse burning semidry method purification techniques device is, in rubbish and lime slurry
Moisture fully enters flue gas and discharged by chimney, causes smoke discharge amount big, chimney emits white cigarette（Water vapour）, the flue-gas temperature of discharge
Low, dew point corrosion easily occurs for chimney, and equipment is complicated, investment is big, operating cost is high, flying dust（Danger wastes）Discharge capacity is big.
The technical scheme to solve the above problems is had no in existing literature.
Utility model content
The purpose of this utility model is aiming at above-mentioned deficiency, there is provided a kind of flue gas of refuse burning is high without white cigarette environment protection emission
Purifier is imitated, the moisture that it can be substantially reduced in rubbish and lime slurry enters the amount of flue gas, can reduce smoke discharge amount, prevents
Only chimney emits white cigarette（Water vapour）Discharge, the flue-gas temperature of discharge is high, and chimney is not susceptible to dew point corrosion, and apparatus and process simplifies,
Investment is reduced, and operating cost is low, flying dust（Danger wastes）Discharge capacity is few, and flue gas of refuse burning high-efficient purification, environmental protection can be achieved
Discharge.
To reach above-mentioned purpose, the technical solution of the utility model is that the flue gas of refuse burning is high without white cigarette environment protection emission
Purifier is imitated, including the incinerator with exhanst gas outlet, the exhanst gas outlet of the incinerator pass through combined type gas-to-gas heat exchanger
It is connected with chilling extracting tower, the chilling extracting tower is connected with cooled dehydrated device, and the cooled dehydrated device passes sequentially through combined type
Gas-to-gas heat exchanger, activated carbon adding device, sack cleaner, air-introduced machine and chimney connect；
The leakage fluid dram of the chilling extracting tower lower end adds alkali pond to be connected with wedged bottom crystallizing pond, and the wedged bottom crystallizing pond adds alkali pond to lead to
The humidifier that lye pump is crossed with chilling extracting tower top is connected, the cooled dehydrated device add respectively with wedged bottom crystallizing pond alkali pond,
Cooling tower is connected, and the cooling tower is connected by recirculated water liquid pump with cooled dehydrated device.
The high-temperature flue gas that the utility model will come out from domestic waste incineration, passed through combined type within about 0.5 second time
Gas-to-gas heat exchanger exchanges heat, and temperature drops to less than 400 DEG C, enters back into chilling extracting tower, is contacted with the alkali lye of closed cycle de-
Acid, flue-gas temperature drop to less than 100 DEG C, while have large quantity of moisture to evaporate into flue gas, and depickling alkali wash water is concentrated by evaporation, when dense
When being reduced to saturation, salts substances crystalline deposit in wedged bottom crystallizing pond, periodically remove, clear liquid is adding alkali pond alkali regulation pH value
Afterwards, it is pumped to chilling extracting tower with alkali lye.
Wet flue gas after chilling depickling, after the dehydration of cooled dehydrated device, temperature is further lowered into less than 50 DEG C, Ran Houjin
Enter the heat exchange of combined type gas-to-gas heat exchanger and be warming up to 140 DEG C or so, cross and filter out into sack cleaner together with the activated carbon of penetrating
Dirt, the flue gas after purification are discharged into air through air-introduced machine by chimney.The flue gas so handled can reach European Union Emission standard, and flue gas
There is 80 DEG C or so of overheat, so chimney discharges phenomenon without white cigarette.
The utility model is used for the processing of waste incineration pyrolysis smoke, and it significantly reduces the water in rubbish and lime slurry
Divide the amount into flue gas, reduce smoke discharge amount, can prevent chimney from emitting white cigarette（Water vapour）Discharge, the flue-gas temperature of discharge
Height, chimney are not susceptible to dew point corrosion, and apparatus and process simplifies, and investment is reduced, and operating cost is low, flying dust（Danger wastes）Discharge
Amount is few, realizes flue gas of refuse burning high-efficient purification, environment protection emission.
