Abstract
The city domestic garbage treating process includes storing fermentation, waste gas and waste water treatment, sorting, stoving, incineration, fume treatment, eliminating slag and other steps. Waste gas produced in the fermentation is used as combustion assisting gas in the incinerating furnace and waste water is conveyed to sewage disposal plant to prevent secondary pollution caused by waste gas and waste water. The sorting and the stoving of fermented garbage before incineration can avoid blocking in hearth, raise heat value, promote combustion and inhibit the production of dioxin. The said process can reduce garbage amount by 95 % and low ignition loss rate of the residue and has low garbage treating cost, and the slag may be used in producing pavement tile and for other uses.
Description
Affiliated technical field
The present invention relates to a kind of treatment process of rubbish, especially the treatment process of domestic waste.
Technical background
The treatment process of traditional domestic waste has three kinds of landfill, compost and burnings, and two kinds of methods of landfill and compost all need take bigger place, and can pollute environment.
On November 27th, 2002 disclosed CN1094802C patent (application number: 97105152) disclose a kind of city house refuse treatment method, be that rubbish is discharged in the accumulator spontaneous fermentation 4-6 days, the draining that oozes that oozes after the fermentation that drop goes out sprays in the incinerator Pintsch process or carries out sewage disposal, the foul smell that produces during fermentation is sent into the incinerator internal combustion and is decomposed, rubbish after the fermentation is sent into the incinerator internal combustion, magnetic separation is sieved after isolating the scrap iron recovery to slag then, thin slag is used to pave the way or improve the soil, and last remaining thick slag is as innoxious covering soil.This treatment process directly will be sent into the stove internal combustion without sorting behind the rubbish fermentation, bulk rubbish in the rubbish or iron wire easily stop up the feeding mouth or the slag notch of incinerator, what influence was burned carries out smoothly, next is that rubbish enters incinerator before without oven dry, this refuse thermal value is little, influence temperature of combustion, easily produce Dioxins, have a strong impact on people's living environment.
Summary of the invention
The purpose of this invention is to provide and a kind ofly can not stop up incinerator, can effectively check the garbage treatment technology that produces Dioxins.
The present invention includes following processing step:
(1), stores fermentation.Fresh domestic refuse is discharged into airtight negative pressure rubbish accumulator, makes rubbish spontaneous fermentation a couple of days.
(2), the processing of waste gas, waste water in the fermenting process.Waste gas in the accumulator extracted to send in the incinerator use wind, make refuse chute maintenance negative pressure excessive simultaneously to prevent foul smell as burning; Send sewage work to handle the waste water in the accumulator.
(3), sorting.Rubbish is sorted, remove bulk rubbish and irony.
(4), oven dry.To send into through the rubbish of sorting utilizes the tail gas after burning to carry out drying as thermal source in the dryer.
(5), burn.Sending into incinerator through the rubbish after the oven dry burns.
(6), flue gas is handled.The flue gas that burning produces is sent into dual firing chamber's high-temp combustion, make it to reach and burn discharging again behind the most state entirely.
(7), cleaning slag.Slag cleaning come out of the stove and screen brickmaking and sell or do his and use.
Because the waste gas that produces in the process that has adopted technique scheme, rubbish to ferment in fermentation vat is burned as combustion air in the stove, has reduced the excessive of waste gas, has prevented the secondary pollution of waste gas; Waste water is sent to sewage work and handles, and has reduced second pollution of wastewater; Rubbish after the fermentation is sent into the incinerator internal combustion after letter sorting, oven dry, overcome the phenomenon of stopping up burner hearth, has improved the calorific value of rubbish, has guaranteed that effectively incendiary carries out and checked the generation of Dioxins smoothly; Slag behind the incineration firing can be utilized fully and make paving brick or make his usefulness, has alleviated the cost of refuse treatment.
Description of drawings
The present invention is further illustrated below in conjunction with drawings and Examples.
Accompanying drawing is a process route view of the present invention.
Embodiment
In embodiment as shown in the figure, concrete processing step is as follows:
(1), storage fermentation:
Fresh domestic refuse is discharged into airtight negative pressure rubbish accumulator, and after rubbish spontaneous fermentation was counted 3-7 days, msw water content reduced about 10%.The air that extracts the rubbish accumulator makes refuse chute keep negative pressure excessive to prevent foul smell as burning air feed.
(2), the processing of waste gas, waste water in the fermenting process:
Waste gas in the accumulator extracted to send in the incinerator use wind, make refuse chute maintenance negative pressure excessive simultaneously to prevent foul smell as burning; Send sewage work to handle the waste water in the accumulator.
(3), sorting:
With the fermentation after rubbish at first rubbish remove irony impurity through magnetic belt separator, again with the rubbish manual sorting, choose bulk rubbish.
(4), oven dry:
Send into rotary dryer through the rubbish of letter sorting and carry out drying, hot blast provides behind the air preheater indirect heat transfer by burning the back high-temperature tail gas.
(5), burn:
Sending into vertical incinerator for thermal decomposition through the rubbish after the oven dry burns.
(6), flue gas is handled:
The pyrolysis gas that rubbish process pyrolysis oven produces enters dual firing chamber with flue gas and aqueous vapor from bottom to top under the road induced draft fan effect of back, flue gas is fully burning under turbulent flow and the peroxide situation, temperature of combustion is 900 ℃ ± 30 ℃, gas residence time was greater than 2 seconds, high-temperature flue gas reaches and burns method removal acidic gas in flue gas and the flue gas particle that adopts behind the most state semidrying depickling to combine with wet dedusting and add bag-type dust entirely, discharge from exhanst gas outlet then, prevented the generation of Dioxins.
(7), cleaning slag:
Slag cleaning after burning is come out of the stove, after screening, can be used as brick-making raw material and sell.
Claims (4)
1, a kind of garbage treatment technology is characterized in that this technology may further comprise the steps:
(1), stores fermentation.Domestic refuse is discharged into airtight negative pressure rubbish accumulator, makes rubbish spontaneous fermentation a couple of days.
(2), the processing of waste gas, waste water in the fermenting process.Waste gas in the accumulator extracted to send in the incinerator use wind, make refuse chute maintenance negative pressure excessive simultaneously to prevent foul smell as burning; Send sewage work to handle the waste water in the accumulator.
(3), sorting.Rubbish is sorted, remove bulk rubbish and irony.
(4), oven dry.To send into through the rubbish of sorting utilizes the tail gas after burning to carry out drying as thermal source in the dryer.
(5), burn.Sending into incinerator through the rubbish after the oven dry burns.
(6), flue gas is handled.The flue gas that burning produces is sent into dual firing chamber's high-temp combustion, make it to reach and burn most state entirely after the depickling dust removal process is discharged again.
(7), cleaning slag.Slag cleaning come out of the stove and screen brickmaking and sell or do his and use.
2, garbage treatment technology according to claim 1 is characterized in that rubbish sorts after fermentation, oven dry is then burned again.
