As illustrated, a temperature sensor 117 is formed to sense the temperature of the combustion chamber 121 inside the supply unit 118 that receives the vaporized fuel provided by the vaporization apparatus 381. When the explosion risk of the temperature sensor 117 is detected, it is configured to prevent the explosion by operating the explosion prevention unit to discharge the gas to block the supply of odor gas.

The combustion unit 120 is connected to the supply unit 118 to form a combustion chamber that burns at the temperature of the heating burner 122 provided at the center of one side, and communicates to the other side of the combustion chamber to form the exhaust gas burned by the odor gas It is configured to be discharged through the discharge port 124 formed in the upper by the operation of the discharge fan 125 through the discharge chamber 123 of the. Here, the barrier rib 126 is formed in the combustion chamber 121 of the combustion unit 120 so as to be discharged to the discharge chamber 123 to open one side from the upper side to the lower side and block the upper side. It is configured to be completely burned by the heating burner 122 while being lightly gasified to prevent the discharge immediately and rotate inside the convection phenomenon.

In addition, by forming an inspection opening for checking the inside of the combustion chamber 121 of the combustion unit 120 to the outside may be configured to check the combustion state inside the combustion chamber 121. The heat recovery unit 130 forms a heat recovery tank 131 having a plurality of recovery pipes 133 folded inside the discharge chamber 123 of the combustion unit 120, and a recovery pipe at a lower portion of the heat recovery tank 131. And a recovery supply unit 132 for supplying water to the discharger 133, and discharges water, which has passed through the recovery tube 133, to the discharge tank formed at one side through the recovery discharge tube 134 connected thereto. The chamber 123 is configured to recover latent heat after combustion.

As described above, when the malodorous gas is supplied to the combustion unit 120 while preventing the explosion, the malodor gas is combusted in the combustion chamber 121 by operating the heating burner 122 whose temperature is controlled by the temperature control unit of the controller. At this time, the barrier rib 126 is formed in the combustion chamber 121 of the combustion unit 120 so as to be discharged to the discharge chamber 123 to open one side from the upper side to the lower side and block the upper side. Light gasification is prevented from being immediately discharged and rotated inside the convection phenomenon is completely burned by the heating burner 122, there is no impurities in the exhaust gas to increase the degree of purification while improving the thermal efficiency.

In addition, by forming a check hole for checking the inside to the outside in the combustion chamber 121 of the combustion unit 120 to check the combustion state in the interior of the combustion chamber 121 to check the interior according to the state of the interior of the combustion chamber 121 To maintain optimum combustion conditions. As described above, the exhaust gas recovered latent heat is discharged due to the operation of the discharge fan 125 of the discharge port 124 formed in the upper portion, is completely combusted in the combustion chamber 1221 and completely purified in the state of recovering the latent heat therein. . Thereafter, the unburned odor is discharged into the air via the cleaning tower 300.

The emulsion sludge treatment system proposed in the present invention extracts refined oil from a fermentation compost manufacturing apparatus using food waste, livestock manure and sewage sludge, purifies wastewater generated during fermentation compost production using refined oil, and at a high temperature. By odor can be removed to induce efficient management of waste and stable treatment of secondary waste, it is believed that industrial use value is high enough to minimize environmental damage.
