Conventionally, in the case of organic wastes as infectious wastes, household waste, and other wastes, it is common to treat them with landfills, but there is a possibility of secondary environmental pollution due to organic matters contained in these wastes, As a result, the life of landfills has been shortened.

In addition, as a method for treating such wastes, a method of incineration is known, but in this case, harmful gases are generated during incineration, which causes a problem of air pollution, and the equipment for incineration is complicated. In addition, it costs a lot of facilities and costs a lot of combustion, which is economically and environmentally undesirable.

In addition, some of the methods of fueling the organic wastes in the form of solid fuels are known. In this case, the solidification through the sorting, drying, mixing, and compacting of the wastes is predominant. The solid fuel thus obtained is not only difficult to solidify the fuel, but also the solid fuel is a method of treatment close to direct combustion, which requires a lot of energy to burn and generates a lot of harmful gases during combustion. As the pollution problem becomes serious, a separate countermeasure must be established to solve this problem, and accordingly, there are many difficulties in practical use, so it is not actually applied.

In addition, there is also known a technique for dry-burning organic waste, in this case, both direct and indirect combustion methods are known, but all of them do not fundamentally solve the problem of incomplete incombustible gas generated during dry and combustion.

In addition, steam and gas generated during pyrolysis are reheated and completely combusted. The heat generated is used as a heating source for organic waste to be treated, and the remaining excess heat can be utilized in terms of recycling waste heat.

Another object of the present invention is to indirectly pyrolyze organic waste, while steam and incomplete combustion gas generated during pyrolysis are completely burned after reheating, thereby maintaining environmental safety during treatment of infectious waste while maintaining safety during treatment. It is intended to be economically handled without causing it.

The carbonized carbide is made to be sequentially operated including a fifth step of separately discharged and recycled.

Let's take a look at each step in detail.

First stage

The first step is to inject the organic waste to the carbonization furnace (1) and to heat in a heater located outside of the carbonization furnace (1) while carbonizing by thermal decomposition while mixing in a sealed state, the organic waste to be treated in the inlet (12) Open the main body 10 and close the inlet 12 to keep the inside of the main body 10 sealed, and the heater 2 heats the interior by the burner 20 to carbonize the organic waste. In this case, the stirrer 16 is operated to uniformly mix or stir the organic waste in the process of carbonization, so that carbonization is uniformly performed.

In addition, the vapor and gas generated from the organic waste in the process of carbonization as described above is fed to the reheat burner (3) via the induction pipe (18).

2nd step

In the second step, steam and gas generated from the organic waste of the carbonization furnace in the first step are fed to the reheat burner 3 to pyrolyze and combust by reheating to change into a hot air flow. Steam and gas fed to the reheater (3) through the flow into the reheating pipe (32) and the reheater (3) is burner 40 operates while the combustion space 30 is heated and burned to the refractory material The steam and gas delivered to the inside of the reheating pipe 32 are heated by the heat treatment 42, and pyrolysis is performed, and the combustion space 30 is mixed with the outside air while the blower 36 is operated at the connection part 34. ) Is supplied to ensure the combustion by the operation of the burner (40).

At this time, since the blower 36 is operated to form a negative pressure including the reheating pipe 32 as a portion adjacent to the connecting portion 34, the induction pipe 18 and the steam and gas generated in the carbonization furnace 1 are formed. The reheating pipe 32 may naturally flow into the combustion space 30.

In this way, the steam and gas in the combustion space 30 via the reheat pipe 32 is changed into a hot air flow form by pyrolysis and combustion by reheating, and the changed hot air flows through the hot air discharge passage 38. Through the supply to the heater (2) of the carbonization furnace (1).

3rd step

The third step is to feed the hot air generated in the second step to the heater (2) of the carbonization furnace (1) to recycle to the heating source of the carbonization furnace (1), the slide opening and closing mechanism 44 is opened And when the slide opening and closing mechanism 60 is closed, the hot air flow generated by the reheater (3) flows into the heater (2) to serve as a heating source for the carbonization furnace (1).

At this time, in order to initially raise the temperature inside the carbonization furnace 1 so that carbonization is possible, first, the burner 20 is operated to meet a predetermined carbonization requirement, and then the hot air flows from the reheating burner 3 in earnest. In the case of being fed to a sufficient heating source to stop the operation of the burner (20) (40) and purely utilized as a heating source by the hot air flow above, in the case of overheating the slide opening and closing mechanism (44) By closing and opening the slide opening and closing mechanism 60 to operate the blower 22 while bypassing the hot air flow, the internal temperature of the heater 2 can be cooled to adjust the temperature of the carbonization furnace 1.

4th step

The fourth step is a step of feeding the hot air flow after recycling in the third step to the condenser (5) and discharge the condensate and internal air generated while passing through the condenser (5) to the outside in a clean state, the heater After utilizing as a heating source in (2) it is fed to the condenser (5) and the hot air is cooled and condensed via the condenser (5), the resulting condensate is discharged to the outside through the drain 52 and the condensate is removed The exhaust gas in the purified state is discharged to the outside via the exhaust port 50.

At this time, the hot air flow generated in the second step is fed directly to the condenser 5 of the fourth step without passing through the third step after the second step, and condensed water and internal air generated while passing through the condenser 5. May be discharged to the outside in a clean state via the drain 52 and the exhaust port (50).

5th step

In the fifth step, the organic wastes are pyrolyzed in the carbonization furnace 1 while repeatedly performing the first to fourth steps, and carbonized carbides are separately discharged and recycled. The organic waste in the state is made is a step that is rapidly reduced in amount and is discharged to the outside by opening the outlet 14 and operating the stirrer 16.

Of course, instead of performing the above-described first to fifth steps sequentially, for example, after the third step, hot air is separately used as another heating source for recycling waste heat, and then the fourth step is performed. It may be.

As described above, according to the present invention, in order to prevent the supply of external air to the inside during the treatment, it is maintained in a sealed state, and thermally decomposed by mixing and heating organic waste, and thus steam and gas generated in the process of pyrolysis After reheating and pyrolysis, it is completely burned and the hot air generated is recycled as a heating source of organic waste, and the remaining hot air can be condensed and discharged or recycled to other heat sources.
