The present invention relates to an incineration apparatus for heat recycling, and in particular, the heat generation means by using light oil, kerosene, banca seed oil, waste oil and LPG, the heat efficiency is high, the high temperature heat introduced into the cone member inside the heat storage tank The waste water with high moisture content is easily dried by introducing into the drying device together with the high pressure air circulating and causing the whirlwind along the outer diameter of the cone member.The waste fuel dried in the drying device is re-injected into the auxiliary fuel input means. The present invention relates to a heat recycling incinerator, which saves resources due to use.

In general, wastewater with a high water content such as sludge, residue, and sludge is disposed of as landfills, which is a major source of deterioration of the natural environment by contaminating soil and groundwater.

To solve this problem, wastes with high moisture content are heated and dried to remove moisture, and sludge is recycled, and the residue can be used as a fertilizer and animal feed (public patent 2001-0078620). Patent Registration No. 0383037) is being developed.

This apparatus is described with reference to the accompanying FIG. 1 as follows.

A waste input device 200 for inputting an appropriate amount of combustible waste in the combustion chamber 100 as shown; A combustion unit 300 installed below the combustion chamber 100 to combust the combustible waste supplied from the waste input device 200; An exhaust port 400 through which exhaust gas combusted in the combustion chamber 100 is discharged; A reburn burner 500 for combusting the combustion gas discharged from the exhaust port 400 again; A reburn chamber 600 in which the flame of the reburn burner 500 is radiated; Drying drum which is connected to the inlet 710 to which the waste supplied by the crusher 700 for inputting and crushing the high water content and the outlet 610 of the reburn chamber 600 are connected and rotated in an inclined state ( 800); An impeller 960 installed inside the drying drum 800 and fixed to the central axis 900 to rotate; It is installed around the inside of the drying drum 800, and consists of a pin 980 for generating a drop impact.

Referring to the conventional operating state configured as described above, various combustible wastes such as various industrial wastes and household wastes are collected, various wastes are put into the hopper 220, and then the motor 210 of the waste input device 200 is operated. By filling the waste into the combustion unit 300, the fuel for initial ignition is supplied, the waste is ignited by the operator to start the combustion to continue the self-burning process by the waste.

At this time, the operator operates a general blower (not shown) for supplying combustion air, and the air pressurized by the blower rises spirally in the combustion chamber 100 and flows into the exhaust port 400.

As described above, the exhaust gas contained in the air introduced into the exhaust port 400 is burned again by the reburn burner 500 installed in the exhaust port 400, so that the temperature of the reburn chamber 600 is increased, and the temperature is increased. The elevated air is introduced into the drying drum 800 through the outlet 610, and is crushed by the crusher 700, and sequentially drying the waste water having a high moisture content flowing through the inlet 710.

At this time, by the pin 980 in the drying drum 800, the injected waste hits the impeller 960 which is rotated while rising and falling and is broken again and exposed to the bone ball by hot air, thereby making it easy to dry.

The waste thus dried is pushed out through the dry discharge part 810 at the other end of the drying drum 800 and can be discharged while falling. The floating material and air are raised to raise the dust collector (not shown) of the dust collecting chamber 990. Pure air is discharged while passing, and the large particles float down to the dust collecting chamber 990 to be discharged to the outside.

However, the conventional waste incineration apparatus configured as described above collects various combustible wastes such as various industrial wastes and household wastes, fills them in the combustion section, and burns them. At this time, the suspended solids (ash) generated while the wastes are burned are burned. As it accumulates in the department, the thermal efficiency decreases, and in order to solve this problem, it is necessary to remove the floating matters from time to time, and the structure, such as supplying a separate fuel for the initial ignition of the waste, becomes complicated. The temperature of the combustion section starts from a low temperature until the temperature of the combustible waste reaches a certain temperature, and after incineration is complete, the temperature of the combustion section decreases again, so dioxin is generated because it cannot maintain a constant temperature continuously. To the harmful gases The problem that soot occurs.

The present invention has been made in order to solve such a conventional problem, the present invention is excellent in thermal efficiency, easy to dry waste water with high moisture content by circulating the high temperature heat with the high-pressure air to whirl to flow into the drying apparatus The purpose of the present invention is to provide a heat recycling incinerator which saves resources by re-injecting the dried waste and using it as auxiliary fuel.
