Description

[Detailed description of the invention] (a) Fields of industrial use General incinerators, waste incinerators, gas generating furnaces, large commercial incinerators, sludge treatment furnaces, livestock excrement incinerators Water heaters and boilers that use solid organic matter as a heat source , burner etc.

B. Conventional technology All existing incinerators, from small ones for general households to large ones for commercial use, use watermarks to promote incineration. However, even if watermarks are used, incineration is not complete, and it takes a long time for the water to burn out after being ignited. In conventional incinerators, the time required for the temperature to rise after ignition, stabilize at high temperature, and then begin to fall again is approximately the same as the time required from the time the temperature begins to fall until the fire is extinguished. In particular, when solid organic matter such as tires is incinerated, the organic matter that cannot be completely incinerated becomes tar or black ash that hardens at the bottom of the incinerator, or is emitted as toxic gas, contributing to pollution. In addition, the tar that accumulates at the bottom not only reduces the performance of the watermark, but also takes time and effort to clean. On the other hand, because watermarks are exposed to high temperatures for long periods of time, they are particularly prone to wear and tear. Some incinerators have adopted water-cooled furnaces to prevent wear and tear, but watermarks are considered consumables and no improvements have been made.

C. Problems to be solved by the invention In order to completely burn solid organic substances, long-term high-temperature combustion is used, but existing incinerators emit smoke and toxic gases, and the remaining ash contains tar and There is a lot of black ash, so it cannot be said that the combustion is complete.

Additionally, the furnace and watermelon are subject to considerable damage as they continue to burn at high temperatures for a long period of time. Watermarks are consumable items and must be replaced frequently, especially in large incinerators, which takes a long time and costs a lot of money to replace. Unburnt tar, black ash, etc. accumulate on the watermark and the bottom of the furnace, smolder for a long time, and eventually harden, so cleaning requires time-consuming work because the remaining ash must be cooled first before being removed.

Watermarks originally create a layer of air between the incinerated material and the bottom of the incinerator, drawing in air and promoting combustion, so the wider the distance between the watermarks, the greater the effect. However, if the intervals between the watermarks are wide, fine incinerated materials or incinerated materials that have burned to a certain extent and have become smaller will fall to the bottom through the watermarks and accumulate without being burned, impeding air flow and causing the watermarks to no longer function as they should. Therefore, in order to continue burning again, the ash that has accumulated at the bottom is scraped out even if it has not completely burned out. Also, if the spacing between watermarks is narrowed, the effectiveness of watermarks will be halved. Therefore, in gas generating furnaces, a blower pipe is placed inside the furnace along with watermarks to promote combustion. It is true that combustion is faster and high-temperature combustion can be sustained, but the blower tubes are subject to high heat and are prone to breakage, which does not solve the problem of watermarks.

D. Measures to solve the problem: Without using watermarks, connect multiple air pipes A with one end closed and vertical holes on the sides and multiple iron plates B of the same length alternately between the air outlet C and the iron plate. The bottom of the incinerator is made by connecting the upper and lower parts alternately so that B faces each other, or molding it into the shape described above, and pouring compressed air E into the blast pipe. Blower pipe A and iron plate B with water layer D on
to cool down.

E. Effect The compressed air sent from the blast pipe blows out from the hole provided on the side of the pipe, hits the steel plate installed opposite the hole, one side rises, the other falls, and there is a space between the steel plate and the blow pipe. Go around the created space.
This creates artificial convection inside the furnace, which ensures a constant supply of air and promotes combustion. As a result, it burns at a higher temperature than conventional ones,
The black ash and tar that fell to the ground without being completely burnt out were blown up by the circulating air, and carried by the rising air, entered the fire again and burned, until everything was completely burnt out. A slight white ash remains. If you simply install an air pipe, no matter where the air outlet is installed, black ash and tar that have not completely burned down and have fallen will enter the air outlet and the pipe, and will gradually accumulate around the pipe. Embed vents and pipes. Therefore, by applying compressed air from the ventilation openings to the iron plate, the air stagnation around the pipes is cleared and black ash and tar are prevented from depositing.

In addition, water-cooled furnaces are already known in which the furnace has a double structure and water is poured between the inner furnace and the outer furnace to prevent damage to the inner furnace. Since it is cooled, it can withstand long-term high-temperature combustion and has little wear and tear.

F. Example It can be used in all the things that conventionally used watermarks, including general incinerators, waste incinerators, gas generators, burners and boilers that use solid organic matter as fuel. It is especially suitable for processing tires, tire chips, textiles, garbage collected from households, food scraps, sludge, livestock excrement, etc., which have been difficult to process due to their inflammability or small size.

G. Effects of the Invention Using the present invention and not using a watermark has the following advantages. Even if the incinerator is the same size as a conventional incinerator, it can process a large amount of waste at one time due to the space created between the watermark and the bottom. If a large amount is input at a time, it can be burned at high temperatures for a longer period of time than conventional materials, so it can be used as a large amount of heat source, and if the solid organic matter is incinerated, it can also be used as an alternative energy source to gas and oil. There is no need to replace the watermark, and since it is constantly water-cooled, it is durable and unaffected by high temperatures. Even small particles that can pass through watermarks can be completely incinerated.

In addition, by using a blower pipe, the air coming out of the blower can be adjusted to the state in which the fuel is most combustible. You can also adjust the temperature and combustion time depending on the application.
Fuel can be used effectively. In addition, since there is no smoldering material, the time from when the temperature of the fire begins to fall until the fire is extinguished is less than half that of conventional methods, allowing the next incineration to be started immediately and providing a continuous heat source.

The remaining ash is completely burned and only a small amount of white ash remains, making it easy to clean and dispose of.

From the above, by using the present invention, it is possible to easily dispose of solid organic matter, which has been difficult to dispose of until now, and it can also be widely used as an alternative energy source, contributing to resource and energy conservation. .
