Abstract

The utility model discloses a system incinerating sludge through smoke waste heat of garbage-incinerating electricity generation. The system incinerating the sludge through the smoke waste heat of the garbage-incinerating electricity generation comprises an organic garbage incinerating furnace, a sludge incinerating and processing device, a conveying device and a smoke purifying device. A hearth smoke outlet of the garbage incinerating furnace is communicated with a gas inlet of the sludge incinerating and processing device through a gas supply pipe. A hot waste gas groove is arranged between the garbage incinerating furnace and the sludge incinerating and processing device. A gas discharge outlet of the garbage incinerating furnace is communicated with the smoke purifying device. A gas discharge outlet of the sludge incinerating and processing device is communicated with the smoke purifying device. An induced draft fan is arranged between the gas discharge outlet of the sludge incinerating and processing device and the smoke purifying device. The smoke purifying device is communicated with a chimney. A discharge outlet of the sludge incinerating and processing device is connected with the conveying device, and the conveying device is further connected with a garbage incineration waste residue pit. The system incinerating the sludge through the smoke waste heat of the garbage-incinerating electricity generation utilizes the waste heat generated by garbage incineration in a recycled mode so as to achieve innocent treatment of the sludge, fully utilizes resources of a garbage incineration plant, reduces steps such as sludge desiccation, desiccated sludge storage and desiccated sludge feeding, and is simple in technology and less in equipment.

Description

Utilize the system of waste incineration and generating electricity fume afterheat burning sludge
Technical field
The utility model relates to the applied technical field of waste incineration and generating electricity fume afterheat, relates in particular to a kind of system that utilizes waste incineration and generating electricity fume afterheat burning sludge.
Background technology
Disposal options such as the landfill that present China municipal sludge mainly adopts, soil utilization, burning electricity generation, there are secondary pollution hidden danger in landfill and soil utilization, and sludge incineration can farthest realize the target of harmless treatment.Low temperature drying technique in the sludge incineration technology is comparatively general both at home and abroad, namely with thermal source the moisture in the mud is evaporated at a lower temperature, advances incinerator again behind the reduction moisture percentage in sewage sludge and burns.The sludge at low temperature drying device is divided into the direct-heating type drying device according to the difference of heat transfer type, indirect heating type drying device, directly-indirectly combined type drying device.It mainly equips sludge at low temperature anhydration and incineration technology: wet mud stores, wet mud conveying, sewage sludge feed, sludge drying, mud discharging, mummification product store, dewatered sludge feeding unit material and dewatered sludge burn unit, exhaust treatment system and Waste Water Treatment etc., and complex process, equipment are various.
The utility model content
The utility model purpose is exactly in order to remedy the defective of prior art, a kind of system that utilizes waste incineration and generating electricity fume afterheat burning sludge simple in structure to be provided.
The utility model is achieved through the following technical solutions:
A kind of system that utilizes waste incineration and generating electricity fume afterheat burning sludge, include incinerator, mud burning treatment apparatus, conveying device and smoke eliminator, the burner hearth flue gas export mouth of described incinerator is communicated with the air inlet of described mud burning treatment apparatus by air supply pipe, be provided with the hot waste gas groove between incinerator and the mud burning treatment apparatus, the exhaust outlet of incinerator is communicated with described smoke eliminator, the exhaust outlet of described mud burning treatment apparatus is communicated with smoke eliminator, be provided with air-introduced machine between the exhaust outlet of mud burning treatment apparatus and the smoke eliminator, smoke eliminator is communicated with chimney, the discharging opening of mud burning treatment apparatus connects conveying device, and conveying device also connects waste incineration waste residue hole.
Be provided with the steam conveyer of band nozzle between described incinerator and the hot waste gas groove.
The utility model has the advantages that: the used heat that the waste incineration of the utility model recycling produces is realized the harmless treatment of mud, the waste gas that sludge incineration produces and waste residue enter in the waste gas waste residue cleaning system that waste incineration produces and together handle, take full advantage of the resource of garbage burning factory, simplify and guarantee when technology reduces equipment not produce secondary pollution after sludge incineration is handled, the utility model is than utilized flue gas of refuse burning waste heat burning sludge technology to compare in the past, reduced drying process, also just reduced the mummification of mud, the storage of dewatered sludge, steps such as the material loading of dewatered sludge, the technology simple device is few.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, a kind of system that utilizes waste incineration and generating electricity fume afterheat burning sludge, include incinerator 1, mud burning treatment apparatus 4, conveying device 3 and smoke eliminator 7, the burner hearth flue gas export mouth of described incinerator 1 is communicated with by the air inlet of air supply pipe with described mud burning treatment apparatus 4, be provided with hot waste gas groove 6 between incinerator 1 and the mud burning treatment apparatus 4, the exhaust outlet of incinerator 1 is communicated with described smoke eliminator 7, the exhaust outlet of described mud burning treatment apparatus 4 is communicated with smoke eliminator 7, be provided with air-introduced machine 9 between the exhaust outlet of mud burning treatment apparatus 4 and the smoke eliminator 7, smoke eliminator 7 is communicated with chimney 8, the discharging opening of mud burning treatment apparatus 4 connects conveying device 3, and conveying device 3 also connects waste incineration waste residue hole 2.The high-temperature flue gas of drawing a part 900 degree from the burner hearth flue gas export mouth of incinerator 1 enter described hot waste gas groove 6 and with after air fully mixes the condition of the oxygen content 9% that reaches sludge incineration, enter described mud burning treatment apparatus 4, mud burns and produces the flue gas of about 250 degree in mud burning treatment apparatus 4, the flue gas that produces is discharged by exhaust outlet, enter described smoke eliminator 7, handle with waste gas generated by burning garbage, discharge by chimney after the gas cleaning, the waste residue that produces after the sludge incineration enters waste incineration waste residue hole 2 by discharging opening and the conveying device 3 of mud burning treatment apparatus 4, handles with the waste incineration waste residue.
Be provided with the steam conveyer 5 of band nozzle between described incinerator 1 and the hot waste gas groove 6.
