Abstract

PURPOSE:To permit the burning disposal of waste oil, mixed with impurities, and/or sludge type waste oil by a method wherein the waste oil is reserved in a trolley while the waste oil is ignited directly to burn it with a large amount of air and at a high temperature. CONSTITUTION:Waste oil is reserved in a trolley 17 in a degree that the head of a ceramic bowl 21, stored in the trolley 17, is submerged, then, the waste oil is ignited directly to burn it. This combustion is assisted by air supplied from an air supplying tubular body 3 and the flame and hot air are brought into the condition of perfect combustion by ventilation through a ventilating tube 8. The waste oil is burnt in the trolley 17 whereby the ceramic bowl 21 is heated and generates far infrared rays which expedite the combustion of the waste oil further. Heat is accumulated in the ceramic bowl 21 by the combustion of waste oil while the accumulated heat assists the combustion of the waste oil. According to this method, the waste oil can be disposed through burning disposal even when the waste oil is mixed with impurities or the waste oil is solidified so as to show the condition of sludge.

By storing the waste oil inside and removing the lid 22a of the chimney 22, residual incomplete combustion gas and the like in the combustion chamber 2 is discharged, which helps safety and improves initial combustion.

When the combustion state becomes good, the chimney 22 is closed to continue the combustion. This combustion is promoted by the air supply from the air supply cylinder 3, and the flame and hot air are further combusted by the air blown from the air blow pipe 8, and the flame guide path C ′ is blown and sucked. Is forcibly guided by.

When the waste oil is burned in the truck 17, the ceramic balls 21 are heated to generate far infrared rays, which further accelerates the burning of the waste oil. Further, the ceramic balls 21 are heated by the combustion of the waste oil, which promotes the combustion.

Feed screw 1 by heat conduction by combustion
The waste oil burns better as 5 is warmed and softens the waste oil supplied. Further, the flame also ignites the waste oil dripping from the inner end delivery portion 12a, and further the supply screw 15
The residual waste oil inside will also be ignited.

The combustion chamber 2 is heated to 100
The temperature becomes higher than 0 ° C. However, the air supply pipe 3
Because the cylinder wall is cooled by passing water to the water passage 7 provided in the cylinder wall, and the blower pipe 8 is also cooled by passing water to the water passage 11 provided in the pipe wall. It withstands the high temperature in 2 and prevents burnout.

Further, since the fixed cylindrical body 14 is cooled by the passage of water to the water passage 13 provided in the fixed cylindrical body 14 of the waste oil supply mechanism 12, the fixed cylindrical body 14 withstands a high temperature and is prevented from burning.

After the waste oil is burned, the slags 17 and 17 are placed so that one dolly 17 is located in the slag discharge chamber 16 which is a standby position and the other dolly 17 is located below the combustion chamber 2. Move and burn slag discharge chamber 1
It can be removed by opening the lid 16a of No. 6 and taking out the ceramic ball 21 from the dolly 17 and cleaning it.

Although the waste oil is burned in this manner, once the temperature inside the combustion chamber 2 becomes high, the inside of the combustion chamber 2 becomes a complete combustion state, so that the incomplete combustion gas disappears, so that the lid 22a of the chimney 22 is removed. There is no need to take it.

The flame and hot air generated in the combustion chamber 2 are forcibly guided and sent out from the flame guiding path C'as described above, so that the flame and hot air are generated, hot water is supplied or metal is melted. It is clear that it can be used as a heat source for other equipment that does such things as.

In the above embodiment, the ceramic balls 21 are housed in the truck 17, but the waste oil can be burned without housing the balls. However, by housing the ceramic balls 21 in the truck 17, the floor surface of the truck 17 is not damaged when the waste oil is burned.
