Description of drawings
Fig. 1 is that the utility model liquid, solid waste three combustion formula burning processing systems connect the layout schematic diagram.
The specific embodiment
As shown in Figure 1, waste incineration processing system of the present utility model comprises preprocessing system, CIU, exhaust treatment system, brick making system, WHRS.
Wherein, refuse burning system comprises rotary furnace, two burners, also comprises three burners, and three burner inlet ends link to each other with the exhaust end of two burners, and exhaust end links to each other with exhaust treatment system.Also be provided with triple valve between the inlet end of described three burners and two burner exhaust ends, triple valve inlet links to each other with two burner exhaust ends, and two one of outlets of triple valve are connected in three burner inlet ends, and another is connected in described exhaust treatment system.This refuse burning system also comprises combustion-supporting system, and this combustion-supporting system comprises ammonia storage tank and the ammonia destruction furnace that connects successively, and ammonia destruction furnace is connected in described rotary furnace, two burners and/or three burners.Described ammonia destruction furnace also is connected with surge tank.
Exhaust treatment system comprises that successively the neutralization reaction tower, the dry type that connect remove acid tower, strap deduster and air-introduced machine, and is connected in the alkali lye pond of neutralization reaction tower, is provided with the alkali lye atomising device between neutralization reaction tower and alkali lye pond.
WHRS comprises cool-heat-exchanger and steam-water separator, and cool-heat-exchanger is arranged between described neutralization reaction tower and the described refuse burning system tail gas outlet side, and steam-water separator is connected in cool-heat-exchanger.
Preprocessing system comprises useless admittedly negative pressure cabin, pretreating device, feed arrangement, the drying oven that connects successively, and the waste liquid tank that is connected with useless admittedly negative pressure cabin, and the output of described drying oven and waste liquid tank is connected with the rotary furnace of refuse burning system respectively.Between described useless admittedly negative pressure cabin and two burners, also be connected with the biogas air-introduced machine.
Its course of work is as follows: rubbish is stored in the rubbish negative pressure cabin after collecting, admittedly the waste liquid that produces in the useless negative pressure cabin enters waste liquid tank to spray in the rotary kiln through atomising device after collecting and burn, the biogas of generation and other gas are sent in the dual firing chamber and are handled.Solid waste enters automatic garbage sorting system, and under the computer Automatic Control, rubbish is divided into three classes: the rubbish of the suitable burning disposal of high heating value, the waste product of recyclable utilization and building waste.The recyclable waste product that sorts out leaves salvage station in.The useless rubbish of building is sent into the brickmaking device and is carried out brickmaking; Combustible is transported in the drying machine through automatic feeder, and the drying before combustible is burned is handled.
Enter after the rubbish of suitable burning disposal is sorted out and carry out the drying processing in the drying oven, send into after the processing and carry out burning disposal in the rotary kiln, flue gas enters dual firing chamber by exhaust gases passes, further fully burn, difference according to treated substance, harmful components are many, not labile material enters three combustion chambers by triple valve and carries out the burning of oxygen enrichment cracking more fully completely, flue gas after the three burner high-temperature process carries out rapid quench through cool-heat-exchanger and cools to 200 ℃, removing in the acid tower and the sour gas in the flue gas by neutralization reaction tower and dry type, deduster is removed the fine solid particle in the flue gas.At last with the free from extraneous odour of allow compliance with emission standards, ordorless, smokeless gas through air-introduced machine by smoke stack emission to atmosphere.Harmful components in burning material are few, easily decompose.After carrying out second-time burning, enter shared exhaust treatment system through dual firing chamber.The lime-ash that burning process produces is collected the back landfill by automatic deslagging device.The discarded object that the neutralization reaction tower produces is handled the back through solidification equipment and is mixed brickmaking afterwards with building waste.The heat that burning process produces is transferred to the waste water boiler after steam-water separator is collected, reclaim or utilization.
Solid waste is transferred to rotary kiln by automatic feeder after super-dry is handled, the temperature in the rotary kiln realizes oxygen debt roasting in kiln between 650 ℃-800 ℃.Burning is not abundant, just contain a large amount of combustibles that does not all burn at the flue gas that forms like this, flue gas enters dual firing chamber by exhaust gases passes, further fully burn, the temperature of dual firing chamber is between 850 ℃-1300 ℃, do burning for the second time to reach the purpose of resolving harmful gas, reduce discharge of harmful gases, combustible in the flue gas is thoroughly burnt, not labile pernicious gas also at high temperature is cracked into gases such as fine solid particle, carbon compound, and PCDF and PCDD are destroyed fully.Difference according to treated substance, harmful components are many, not labile material enters three combustion chambers by triple valve and hangs down the nitrogen burning, the temperature of three combustion chambers is between 650 ℃-500 ℃, by reducing flame face localized hyperthermia district's temperature, the quantity delivered and the feed point of control auxiliary air reduce excess oxygen content and shorten its time of staying on the flame face, effectively suppressed the generation of NOx, and when reducing NOx, also neutralized CO (carbon monoxide), H2, C and CnHm.The NOx that has not only generated in burner hearth (combustion chamber) obtains reduction, also can suppress new NOx simultaneously and generate, and the concentration of emission of NOx is further reduced.At last, combustion product enters burning-out zone, and PCDF and PCDD are difficult for generating at low temperatures.Flue gas after the processing enters exhaust treatment system and handles.Harmful components in burning material are few, when easily decomposing, after carrying out second-time burning through dual firing chamber, can directly enter shared exhaust treatment system.
Flue gas enters cool-heat-exchanger from flue, and rapid quench cools to 200 ℃, has avoided generation PCDF and PCDD to form vigorous warm area.The dust of larger particles begins to fall in the cinder catcher of cool-heat-exchanger under the situation that temperature reduces.So just reduced the processing load of equipment subsequently.Alkali lye is by the abundant combination of the sour gas in atomising device and the flue gas in the neutralization reaction tower, and most sour gas has neutralized.Dry type is removed in the acid tower and remaining sour gas and unnecessary alkali lye, keeps the drying in the flue gas.Deduster filter in the flue gas fine solid particle and.Adopt pulsative oscillation that dust is shaken off at ash-collecting port.In the end with the free from extraneous odour of allow compliance with emission standards, ordorless, smokeless gas through air-introduced machine by smoke stack emission to atmosphere.
