Abstract
The utility model relates to a pneumatic controlled harmless medical refuse thermal cracking apparatus, which comprises a closed rubbish garage, and the inside of the rubbish garage is provided with a rubbish claw hanging, and a rubbish supply machine is positioned under the rubbish claw hanging and connected with a combustion chamber through a declined pipe. A sewage pool is positioned under the rubbish garage and connected with the feeding end of one combustion chamber. The upper end of the rubbish garage is connected with the air preheater of the second combustion chamber through a primary fan. The upper end of the second combustion chamber is in turns connected with a temperature reducer, a flue gas dust remover, a purifying tower, a draught fan and a chimney. The utility model has the advantages that: the utility model adopts the rotary kiln as a combustion chamber combining a second high-temperature combustion chamber, which is suitable for the medical rubbish characteristic in our country. The utility model is of big disposal amount, complete disposal and low working intensity for the workers and the flue gas exhausting reaches the standard, and the utility model has no secondary pollution. The device is also can be extended to the disposal field of other dangerous rubbish.
Description
Technical field
The utility model relates to a kind of waste disposal method, relates in particular to the innoxious integrated treating device of a kind of medical waste Pneumatic-control type pyrolytic incineration.
Background technology
" national hazardous waste register " regulation medical waste comprises hospital clinical refuse and useless medicine, the medicine two big classes of giving up.Medical waste contains a large amount of germs, virus and other harmful substances, is therefore classified as No.1 danger wastes by country.At present, national regulation adopts closed burning disposal to medical waste.
Characteristics such as China's medical waste has moisture height, complicated component, do not classify are directly quoted foreign technology and are existed technical obstacle, and cost an arm and a leg, and economy is relatively poor, is difficult to apply.And the domestic technique ubiquity handle thoroughly, can not continuous-feeding and exhaust emissions shortcoming such as exceed standard.
Summary of the invention
The purpose of this utility model provide a kind of small investment, disposal ability strong, medical waste is handled fully and the innoxious integrated treating device of medical waste Pneumatic-control type pyrolytic incineration of the continuous operation that exhaust emissions is up to standard.
It has closed rubbish storehouse, being provided with rubbish in the rubbish storehouse grabs and hangs, rubbish grab hang have the garbage feeding machine and through inclined tube and one the combustion chamber link to each other, the rubbish storehouse is divided into cesspool and is linked to each other with a combustion chamber feed end through sewage pump, rubbish storehouse upper end links to each other with air preheater in the dual firing chamber through primary air fan, links to each other through deduster, purifying column, air-introduced machine, chimney with attemperator, flue gas successively on the dual firing chamber.
The utility model effect is:
1) because the version of rotary kiln is adopted in a combustion chamber, make the utility model can handle the discarded object of various forms; Rotary kiln tilts to place, and tilt adjustable is carried out further oven dry, pyrolysis, the burning of medical waste in body of heater automatically continuously; Rotary kiln makes medical waste constantly mix with certain rotating speed revolution, is heated evenly, and handles thoroughly.
2) in dual firing chamber under the hot environment (850 ℃～1100 ℃), flue gas stops certain hour, and (combustible component and a small amount of harmful substance of 1.5s～2s) a combustion chamber is produced are fully burnt, are decomposed, and remove stink simultaneously, reach processing intent.
3) adopt rotary kiln as a combustion chamber,, can satisfy the use needs of various processing medical waste field points so it can be designed to the type of furnace of high throughput in the unit interval.
4) owing to adopt rotary kiln as a combustion chamber, peripheral maintenance is simple, and the workman need not directly to contact medical waste, and labour intensity is low.
5) the utility model adopts the measure that comprehensively prevents secondary pollution, by multistage gas control mode, strengthens the stove internal combustion, reaches medical waste harmless treatment purpose.Be further cleaning of off-gas, the device that integrates dedusting and remove harmful components (as heavy metal, HCL, HF, H2S, SO2, Nox, dioxin etc.) be installed, pollutant emission is strict controlled in the national standard at afterbody.Slag is dry state discharges, and no pit waste water does not also need to handle the equipment of heavy metal containing sewage; Waste water in the refuse chute can be in the indoor atomizing burning disposal of sending forth of a combustion.
6) rotary structure of the utility model incinerator also can be applicable to other danger wastes process field.
Description of drawings
Accompanying drawing is the structural representation of the innoxious integrated treating device of medical waste Pneumatic-control type pyrolytic incineration.
The specific embodiment
The innoxious integrated treating device of medical waste Pneumatic-control type pyrolytic incineration has closed rubbish storehouse 1, being provided with rubbish in rubbish storehouse 1 grabs and hangs 2, rubbish grab hang have garbage feeding machine 5 and through inclined tube and one the combustion chamber 7 link to each other, rubbish storehouse 1 is divided into cesspool 14 and is linked to each other with a combustion chamber 7 feed ends through sewage pump 15,1 upper end, rubbish storehouse links to each other with air preheater 4 in the dual firing chamber 8 through primary air fan 3, and dual firing chamber 8 upper ends link to each other through deduster 10, purifying column 11, air-introduced machine 12, chimney 13 with attemperator 9, flue gas successively.
A said combustion chamber 7 is a rotary kiln, tilts to place, and is driven by main drive motor 6, and an end is provided with material inlet and combustion-supporting, and inside is provided with thermocouple, and the other end links to each other with dual firing chamber 8, and the bottom is provided with slag-drip opening
Medical waste is transported in the factory inner sealing formula rubbish storehouse by the airtight automobile of special use, and rubbish is unloaded at rubbish storehouse one end.Grab to hang with rubbish rubbish is grabbed into the garbage feeding machine, it is indoor to slip into a combustion by inclined tube behind the garbage feeding machine.One combustion chamber is turned round with specific speed by main drive motor.The sewage that the rubbish storehouse produces flows into cesspool, beats to a combustion chamber feed end through sewage pump, sprays in the stove and burns, and wastewater treatment is fallen.
The air that burns usefulness is sucked in the rubbish storehouse by primary air fan and send into dual firing chamber behind air preheater, to keep the negative pressure of rubbish storehouse, prevents that foul smell is excessive.
Rubbish is after a combustion chamber pyrolytic incineration, and the flue gas of generation enters dual firing chamber to be continued to burn, and fully reacts to guarantee a combustion chamber uncombusted composition, and a small amount of dioxin that while one combustion chamber produces can fully decompose destruction.The flue gas of dual firing chamber outlet enters attemperator after air preheater, flue-gas temperature is cooled to rapidly below 200 ℃, and flue gas enters purifying column and goes out sour gas after the deduster dedusting, cause the smoke stack emission atmosphere by air-introduced machine.
