In general, the incinerator is an incinerator for burning waste, a boiler for use as energy by using the high temperature of the exhaust gas discharged from the incinerator, and a reaction for removing harmful gases and foreign substances from the exhaust gas passing through the boiler. It is composed of a tower and a bag filter, and a stack to discharge the clean gas discharged from the air to the atmosphere, and the incineration device is burned by introducing excess air, which limits the heat generation amount due to the high moisture content of the waste. There was a difficulty in high temperature combustion.

In addition, when the waste is burned, various harmful gases are contained in the exhaust gas, and chemicals are used to remove the harmful gases. However, there is a limit in discharging the harmful gases as clean gas, and various methods such as slaked lime, activated carbon, and ammonia are used. Eggplant uses the drug, so there is a problem that requires a lot of operating costs.

In addition, with the seriousness of environmental problems, social disputes are increasing day by day, and there are serious disputes between administrations and residents or between regions and regions over the location selection, construction and operation of waste treatment facilities in various parts of the country. It is reaching degree.

On the other hand, various incinerators have been conventionally conceived. For example, "Vortex waste incineration apparatus" of Korean Utility Model Registration No. 318849 has been conceived.

As described in the claims of the registered publication, an incinerator in which a waste storage chamber is formed at an inner lower side, a combustion chamber is formed above the waste storage chamber, and an air inlet is formed at an upper side thereof, and an air passage is formed between the incinerator. A case which surrounds the incinerator to be formed and an air inlet is formed at a lower side thereof, and a exhaust pipe is formed at an upper side thereof; An ignition means for lighting the waste contained in the waste storage compartment, a partition for dividing the air passage up and down to form a first air passage downward and a second air passage upward, and entering the first air passage; Blowing means for forcibly supplying air to the combustion chamber through the second air passage, and the upper portion of the case to prevent the air supplied to the combustion chamber by the blowing means flow into the flue pipe and to guide the combustion chamber Guide means installed inside, an air nozzle which is installed to inject air to the smoke flowing into the flue pipe to the lower side of the flue pipe to burn the incomplete combustion material contained in the smoke, and the waste storage chamber And a waste supply means for supplying the incinerator and the case to coil the spiral wound on the inner wall surface. Is added to the embossed formed and characterized in that the bone formed between the embossment.

As another example, Korean Utility Model Registration No. 397586, a "waste incinerator," has been devised, which can be seen by the claims of the registered publication, where a waste input hopper is formed at the top and the waste is burned inside. The combustion chamber is provided so that the combustion chamber is provided at the lower end of the incinerator having a combustion material outlet, it is installed to be connected to the pipe on one side of the incinerator, waste heat boiler to produce steam using the high temperature recycle gas discharged from the incinerator as a heat source, the It is installed to be connected to the pipe on one side of the waste heat boiler, the reaction tower to reduce the temperature of the recycle gas discharged from the waste heat boiler and remove the harmful gas, is installed to be connected to the pipe on one side of the reaction tower, the reaction inside Bag filter provided with a filter to remove harmful substances contained in the recycle gas discharged from the tower, the bag A recirculation gas recirculation means consisting of a supply pipe connecting the bag filter and the combustion chamber to recirculate the recirculated gas discharged from the gas to the combustion chamber of the incinerator, and a blower installed on the supply pipe to blow the recirculating gas, and installed to be connected to the supply pipe. And an air supplement means for selectively replenishing air according to the amount of recycled gas to be recycled.

Therefore, by recycling the combustion gas burnt in the incinerator to use as a heat source to reduce the various harmful substances contained in the combustion gas to reduce the cost burden due to the use of various chemicals.

However, it is difficult to expect a large effect because the combustion ratio of the circulating combustion gas is small, and there is a problem in that the components are complicated and thus a large burden on the installation cost.

The present invention has been made to solve the problems of the conventional waste incinerator as described above, and the combustion gas burnt in the primary incinerator is instantaneously compressed and exploded by the ignition burner in the secondary combustion chamber, and also by a conical porous plate.
