Description
Affiliated technical field
The present invention be a kind of rapidly and efficiently, the method for the sludge treating system of environmental protection and energy saving, relate to or rather a kind of continuous high speed, the not only processing method of the sludge treating system of energy-conservation but also environmental protection.
background technology
At present concentrated, the sludge digestion of the domestic general employing mud of sludge treatment technique, sludge dewatering, drying bed, sanitary landfill, or agricultural after digestion, what also have is directly concentrated rear agricultural, but in mud, contain a large amount of pathogenic micro-organisms and remain heavy metal ion, its biochemical property is very unstable, after the direct sanitary landfill of most of mud, has not only caused the waste of resource, also cause the secondary pollution to environment simultaneously, thereby human health is worked the mischief.
summary of the invention
In order to overcome the deficiency of above-mentioned current sludge treating system, the invention provides a kind of rapidly and efficiently, sludge treatment device and the method for environmental protection and energy saving, not only energy-conservation but also environmental protection and can continuous high speed, the technique of the sludge treating system that unit day output is large.
The technical scheme that the present invention solves its technical problem is:
A kind of rapidly and efficiently, the equipment of environmental protection and energy saving sludge treating system is mainly comprised of feeding unit, sludge drier, standby boiler, sludge carbonization stove, temperature controller, I temperature sensor, II temperature sensor, fly-ash separator, wet cleaner, Photochemical deodorization device, cooling humidifier, storage bin, induced draft fan, gas blower and valve etc.Between them, by airduct, communicate with each other.Wherein: the external hopper of feeding unit, the built-in spiral conveyer with governor mechanism; Sludge drier is stir shaft revolving drum drier, external opening for feed and discharge port, and built-in I temperature sensor and high-speed stirring apparatus, its main shaft is placed in the center of revolving drum shell; In sludge carbonization stove, establish the spiral conveyer up/down perforation by 4～6 sections, and on spiral conveyer shell, be provided with some apertures, in stove, bottom arranges preheating oven, burner and II temperature sensor that built-in ratio regulates, for providing temperature controller to control the automatic operation of preheating oven, stove internal upper part arranges burner again; Thermal source when standby boiler is used for providing sludge drier to start to start, and the burner of built-in ratio adjusting, for providing temperature controller to control the automatic operation of standby boiler.
A kind of rapidly and efficiently, the treatment process of environmental protection and energy saving sludge system, its processing step is: (1) starts sludge drier and dust-removal system, light standby boiler and control the hot blast temperature enter sludge drier and reach while drying design temperature, wetter mud is dropped into sludge drier through the feeding unit of the spiral conveyer with governor mechanism and stir mummification, (2) when the wet moisture percentage in sewage sludge in sludge drier reaches 30% left and right, light the preheating oven of sludge carbonization stove bottom, and the spiral conveyer starting in sludge carbonization stove transmits the dewatered sludge from top to down from sludge drier discharge port, the high temperature that the now preheating oven of sludge carbonization stove bottom burning is produced, by the dewatered sludge heating in spiral conveyer, dewatered sludge charing gradually under this high temperature anoxic condition, produce the carbonizing gas being formed by hydrocarbon polymer in a large number, this carbonizing gas is after spiral conveyer shell is provided with in aperture and overflows, under furnace high-temperature with air in oxygen combustion, the hot flue gas of its generation enters the post-heating to 800 of the burner again ℃ high temperature on sludge carbonization stove top, carcinogens Dioxins in mud is decomposed completely, kill various pathogenic micro-organisms completely, hot flue gas in sludge carbonization stove after burning is sent sludge drier by airduct back to through standby boiler after the burning of burner again on sludge carbonization stove top, the thermal source that is used as sludge drier, the enough sludge drier dewatered sludges of hot flue gas of producing when sludge carbonization stove take, temperature controller is controlled the proportioning burner auto extinguishing in standby boiler by the I temperature sensor being placed in drying machine, and sludge treating system enters continuous production run, (3) the used heat moisture that sludge drier is discharged, after fly-ash separator dedusting, by induced draft fan, transmitted, a part is admitted to sludge carbonization stove recycling, temperature controller is controlled the temperature in the automatic regulating stove of its proportioning burner by the II temperature sensor being placed in the preheating oven of sludge carbonization stove, with save energy, the useless moisture of another part is after wet cleaner and Photochemical deodorization device, by safety dumping, meanwhile, the mud granule after the charing of sludge carbonization stove, because it is containing having surplus heat and 0% water ratio, is cooled through cooling humidifier, and enters storage bin after the anti-spontaneous combustion of humidification.
As preferred version of the present invention, the carbonization temperature in described sludge carbonization stove is 500 ℃～700 ℃.
As preferred version of the present invention, the hot blast temperature in described sludge drier is 750 ℃～850 ℃, and the rotating speed of the stir shaft in sludge drier is 250～350 revs/min, and the rotating speed of revolving drum is 2～5 revs/min.
Hence one can see that: at the beginning of this system starts, the required thermal source of sludge drier is to be provided by standby boiler, and after system starts, the hot flue gas that the required thermal source of sludge drier is produced by sludge carbonization stove carries out sludge drying as thermal source.Meanwhile, a part for the useless damp-heat that sludge drier is discharged is sent into sludge carbonization stove recycling, has fully recycled the thermal source of mud to reach energy-conservation object; After system starts, i.e. continuously-running, lignin-sludge amount is large, and speed is fast; Simultaneously, the high temperature that produces 800 ℃ by the flammable carbonizing gas that burns evaporates the moisture in mud, a large amount of weight and volumes that reduce mud, and carcinogens Dioxins is decomposed completely, effectively suppress the generation of Dioxins, kill various pathogenic micro-organisms completely, after charing, form the carbonization product that is rich in fixed carbon, reduce in a large number CO
2discharge, other heavy metal ion (as: Pb, Cd, Cr, Ni etc.) will be cured in carbide product, become highly stable and to environment without harm; And in the dust in sludge treating system, adopt induced draft fan safety dumping after fly-ash separator, wet cleaner, Photochemical deodorization device.So sludge treating system of the present invention is both energy-conservation, again environmental protection and can continuous high speed lignin-sludge, this is the project being worthy to be popularized.
