Description
Affiliated technical field
The present invention be a kind of rapidly and efficiently, the Apparatus and method for of the sludge treating system of environmental protection and energy saving, relate to a kind of continuous high speed, the not only equipment and the technology thereof of the sludge treating system of energy-conservation but also environmental protection or rather.
Background technology
At present the domestic general employing mud of sludge treatment technique concentrate, sludge digestion, sludge dewatering, drying bed, sanitary landfill, or the digestion back is agricultural, also have directly to concentrate the back agricultural; But contain a large amount of pathogenic micro-organisms and residual in the mud heavy metal ion is arranged; 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 simultaneously, thereby human health is worked the mischief second environmental pollution.
Summary of the invention
In order to overcome the deficiency of above-mentioned present sludge treating system, the present invention provide a kind of rapidly and efficiently, the 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 equipment of the sludge treating system that the unit day output is big and technology thereof.
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 mainly is made up of feeding unit, sludge drier, standby boiler, sludge carbonization stove, temperature controller, I TP, II TP, fly-ash separator, wet cleaner, photochemistry deodorizer, cooling humidifier, storage bin, induced draft fan, gas blower and valve etc.Communicate with each other through airduct between them.Wherein: the external hopper of feeding unit, the built-in spiral conveyer that has governor mechanism; Sludge drier is the stir shaft revolving drum drier, external opening for feed and discharge port, and built-in I TP and high-speed stirring apparatus, its main shaft places the center of revolving drum shell; Establish spiral conveyer up/down perforation in the sludge carbonization stove by 4～6 sections; And on the spiral conveyer shell, be provided with some apertures; The bottom is provided with preheating oven in the stove; Burner and II TP that built-in ratio is regulated are used to provide the automatic operation of temperature controller control preheating oven, and the stove internal upper part is provided with burner again; Thermal source when standby boiler is used to provide sludge drier to begin to start, and the burner of built-in ratio adjusting are used to provide the automatic operation of temperature controller control standby boiler.
A kind of rapidly and efficiently, the treatment process of environmental protection and energy saving sludge system; Its process step is: (1) starts sludge drier and dust-removal system; When lighting hot blast temperature that standby boiler and control gets into sludge drier and reaching the oven dry design temperature, the mud that will wet again drops into sludge drier through the feeding unit of the spiral conveyer that has governor mechanism and stirs mummification.When (2) treating that the interior wet moisture percentage in sewage sludge of sludge drier reaches 30% left and right sides; Promptly light the preheating oven of sludge carbonization stove bottom, and the spiral conveyer that starts in the sludge carbonization stove will transmit the high temperature that the preheating oven burning of sludge carbonization stove bottom is at this moment produced from the dewatered sludge from top to down of sludge drier discharge port; Dewatered sludge in the spiral conveyer is heated; Dewatered sludge charing gradually under this high temperature anoxic condition produces the carbonizing gas of being made up of hydrocarbon polymer in a large number, and this carbonizing gas is provided with the aperture after the effusion from the spiral conveyer shell; Oxygen combustion under furnace high-temperature and in the air; The hot flue gas of its generation gets into the post-heating to 800 of the burner again ℃ high temperature on sludge carbonization stove top, and the carcinogens Dioxins in the mud is decomposed fully, kills various pathogenic micro-organisms fully; Hot flue gas after the sludge carbonization stove internal combustion is sent sludge drier through 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; When the enough sludge drier dewatered sludges of the hot flue gas of sludge carbonization stove production take; Temperature controller is by the proportioning burner auto extinguishing in the I TP control standby boiler that places in the drying machine, and sludge treating system promptly gets into the continuous production operation.(3) the used heat moisture of sludge drier discharge; After the fly-ash separator dedusting, transmit by induced draft fan; A part is admitted to the sludge carbonization stove and utilizes; Temperature controller is regulated the temperature in the stove automatically by its proportioning burner of the control of the II TP in the preheating oven that places the sludge carbonization stove, with save energy; The useless moisture of another part is behind wet cleaner and photochemistry deodorizer, by safety dumping; Simultaneously, the mud granule after the charing of sludge carbonization stove has surplus heat and 0% water ratio because of it contains, and is cooled through the cooling humidifier, and gets into storage bin after the anti-spontaneous combustion of humidification.
As preferred version of the present invention, the carbonization temperature in the said sludge carbonization stove is 500 ℃～700 ℃.
As preferred version of the present invention, the mummification temperature in the said sludge drier is 750 ℃～850 ℃, and the rotating speed of the stir shaft in the sludge drier is 250～350 rev/mins, and the rotating speed of revolving drum is 2～5 rev/mins.
Hence one can see that: at the beginning of this system started, the required thermal source of sludge drier was to be provided by standby boiler, and after system started, the required thermal source of sludge drier carried out sludge drying by the hot flue gas that the sludge carbonization stove produces as thermal source.Simultaneously, the part of the useless damp-heat that sludge drier is discharged is sent into the sludge carbonization stove and is utilized, and the thermal source of fully having recycled mud is to reach purpose of energy saving; System can move after starting continuously, and it is big to handle sludge quantity, and speed is fast; Simultaneously; The high temperature that produces 800 ℃ through the flammable carbonizing gas of burning evaporates the moisture in the mud, reduces the weight and volume of mud in a large number, and the carcinogens Dioxins is decomposed fully; Effectively suppress the generation of Dioxins; Kill various pathogenic micro-organisms fully, form the carbonization product that is rich in fixed carbon after the charing, reduce CO in a large number
2Discharging, other heavy metal ion (as: Pb, Cd, Cr, Ni etc.) will be cured in the carbide product, become highly stable and environment is not had harm; And adopt induced draft fan safety dumping behind fly-ash separator, wet cleaner, photochemistry deodorizer in the dust in sludge treating system.So sludge treating system of the present invention was both energy-conservation, environmental protection and ability continuous high speed are handled mud again, and this is the project that is worthy to be popularized.
