The gas that described exhaust outlet 12 is discharged is the gas of organic matter after decomposing mostly, is the fuel gas of mixing, uses after caning be passed through purification as fuel;
The second described combustion chamber 15 is mainly used for again burning unburnt particle, flue dust in the first combustion chamber 6.Be provided with interlaced analysing in the second described combustion chamber 15 and flow plate 18, described interlaced analysing flows plate 18 for stopping flue dust, makes flue dust in the second combustion chamber 15, stop time enough to complete its burning; So two pieces of interlaced length summations analysing stream plate 18 are at least greater than the total height of the second combustion chamber 15, the described width of analysing stream plate 18 is preferably equal with the width of the second combustion chamber 15;
Be provided with plasma spraying 16 in the second described combustion chamber 15, described plasma spraying 16 is preferably disposed on two pieces and analyses between stream plate 18, and the flue dust time of staying of this position is longer, and time enough can be had to burn; Described plasma spraying 16 preferably adopts aura injector head;
The feature of the second described combustion chamber 15 is that temperature is high, decomposition rate soon, at high temperature hazardous waste will all be decomposed by efficient cracking, most of virus spread and other poisonous and harmful substance, reach thorough nontoxicization; This mode also can make incineration firing more stable, improves firing efficiency;
Described plasma spraying 16 is connected with plasma converter 27 by special transfer tube 17, the plasma that described plasma converter 27 produces is conducted into plasma spraying 16 by special transfer tube 17, and the plasma spraying of process 16 sprays into mixed combustion abundant with flue dust in the second combustion chamber 15;
Described plasma converter 27 is placed on supporting clapboard 23;
Gas after burning in the second combustion chamber 15 can enter flue gas disengagement chamber 24, chimney 19 is provided with in described flue gas disengagement chamber 24, gas after second-time burning can be separated in flue gas disengagement chamber 24, its particle to sink down into bottom flue gas disengagement chamber 24 and to discharge through flue gas disengagement chamber ash discharging hole 25, and the gas after separation can enter chimney 19 and discharge;
The gas that the described air inlet of chimney 19 in flue gas disengagement chamber 24 is preferably lower than the second combustion chamber 15 enters the import of flue gas disengagement chamber 24, such energy, to the enough disengaging time of the flue gas entered in flue gas disengagement chamber 24, avoids the flue gas with particle to be discharged by chimney 19;
Described fire grate 4 is provided with plasma nozzle 30, described plasma nozzle 30 is connected with plasma converter 27 by plasma tube connector, during use, combustion-supporting to jet plasma in the first combustion chamber 6 by plasma nozzle 30, during to ensure the incineration firing in the first combustion chamber 6, there is sufficiently high temperature, prevent from generating the harmful substances such as dioxin;
Described blower fan 28 adopts cold wind oxygen supply, and it can queue cooling effect to stationary furnace, in case the too high fire grate of temperature is out of shape, fusing;
Described plasma nozzle 30, can directly dry and combustion-supporting medical waste, improves ignition temperature and speed;
In order to prevent the too low and economize energy of ignition temperature further, can at the first top, combustion chamber 6 set temperature auto-controlling apparatus 8, described temperature-controlled instrument 8 can temperature in Real-Time Monitoring first combustion chamber 6, when temperature is too low may produce the harmful substances such as dioxin time, it can start plasma converter 27 and transmit plasma to plasma nozzle 30, and passes through plasma nozzle 30 to rubbish jet plasma to improve ignition temperature.Certainly, when the temperature in the first combustion chamber 6 is enough, described temperature-controlled instrument 8 can control plasma converter 27 to be stopped in plasma nozzle 30, transmitting plasma, with economize energy;
The cooling chamber 7 for cooling whole body of heater is provided with outside described combustion furnace;
Described chimney 19 passes combustion furnace portion outboard and is provided with cooling water tank 20, described cooling water tank 20 is built with cooling water, described cooling water tank is also connected with cooling chamber 7 by cooling water pipe 21, certainly described cooling water pipe 21 preferably arranges gate valve 22, flows into the flow in cooling chamber 7 by gate valve 22 controlled cooling model water; Be provided with delivery port 26 bottom described cooling chamber 7, the cooling water after body of heater heating can be discharged by delivery port 26 and be used, and reaches energy recovery;
The ignition temperature of the first described combustion chamber is 800-1300 DEG C, and the ignition temperature of the second combustion chamber is greater than 1500 DEG C, and the time of staying is at least 2s.
Plasma be one there is high enthalpy, high temperature, reaction time fast, concentration of energy, electric conversion efficiency high (being greater than 90%) can the new thermal source of commercial Application, discarded object shape can not be selected when processing medical waste and indusrial toxic harmful hazardous waste, process range is wide, and applicability is strong.When medical waste, poisonous and harmful industrial waste (solid, gas, liquid) are put into after in this incinerator, 1200 DEG C ~ 3000 DEG C can be reached in signa, make organic waste in the plasma, rapid dehydration, pyrolysis, cracking, the mixing imflammable gas that to produce with H2, CO, CH4 and other organic gas be main component.
With the time constant of plasma oneself for feature, because ignition temperature in stove is greater than 1200 DEG C, the transmitting of volatile matter and burning, pyrolysis, cracking all complete within moment.Reach through second-time burning again and subtract appearanceization, nontoxicization.The meltings under action of plasma such as inorganic matter (metal, glass), also reach nontoxicization and subtract appearance object.
Very the important point is, utilize plasma treatment Special Wastes to be non-single combustion process, and reaction temperature is more than 1200 DEG C, thus can not produce the harmful substances such as dioxin.
Plasma Special incinerator for medical garbage is the novel environment friendly device replacing traditional handicraft process medical waste, has higher pyrolysis ability.Do not use the traditional fuel such as oil, natural gas, quick heating, after 5 points of kinds of starting shooting, can medical refuse burning be dropped into.
Many regular medication incinerators are in low temperature (less than 800 DEG C) disposal of refuse.In incinerator, the adhesion of chlorine is very strong, can generate chloride with after other element reactions, is the misfortune source producing dioxin.Chloride, HCl gas are the arch-criminals producing dioxin, and the dioxin of about 80% ~ 90% therefrom generates.In addition, identical with chlorine, the bromine, fluorine, iodine etc. of halogen system also have flame-retarding characteristic, can form cryosphere, produce dioxin on furnace flame surface.And plasma treatment garbage system high temperature borning away refuse more than 1200 DEG C, fully decompose, the formation of dioxin can be prevented.
More than describe preferred embodiment of the present utility model in detail.Should be appreciated that those of ordinary skill in the art just can make many modifications and variations according to design of the present utility model without the need to creative work.Therefore, all technical staff in the art according to design of the present utility model on the basis of existing technology by the available technical scheme of logical analysis, reasoning, or a limited experiment, all should by the determined protection domain of claims.
