[Detailed Description of the Invention] [Industrial field of application] This invention produces a large amount of toxic soot and odor when incinerated under normal conditions. For example, old tires, belts, waste electric wires, plastic film waste materials. , Waste of petrochemical products such as PVC products (water pipes, signs, etc.), plywood and other combustible industrial wastes are incinerated with almost no smoke and odor, and the charcoal of the cinders is burned on the rustle It relates to the technology of a waste incinerator where there is no sticking and the furnace can be maintained and managed only by cleaning the incineration ash.

[Conventional technology]

When incinerating a large amount of the above-mentioned types of industrial waste, if they are incinerated as they are, a large amount of harmful soot and offensive odors will be generated. It is used to oxidize and discharge soot and odors, or to bury it as it is without incineration, but in the former case, the incineration temperature is too high and the service life of the furnace is short. Each method has its advantages and disadvantages, and the increasing amount of this type of industrial waste collected and disposed is not enough to keep up with the amount generated. There is a problem that it is not appropriate to dispose of this type of petrochemical product waste easily and safely that does not cause the above-mentioned pollution, which is generated in a familiar manner in a certain amount. Relatively low cost It has been desired to develop this type of industrial waste incinerator that is wasteful, has a long service life, is pollution-free, can be operated by anyone, and is easy to maintain.

[Problems to be solved by the device]

In view of the above circumstances, the present invention uses an incinerator having a simple structure and a long life, requires almost no smoke and odor of industrial waste of the above-mentioned type, and requires a long radiating cylinder (chimney) facility. It can be incinerated without any effort, easily for anyone,
It is an object of the present invention to provide a waste incinerator that can be safely operated and that can easily dispose of incinerated materials.

[Means for Solving the Problems]

In order to achieve the above-mentioned object, the waste incinerator of the present invention comprises the following constituent elements.

(1) Sealing with a combustion air supply adjusting port provided on one open end side of a combustion chamber having a combustion air supply pipe installed at the bottom with a slant in the upper part and in an oblique direction at the upper end The front lid is attached so as to be openable and closable, and the other closed end side is communicated with the combustion chamber, and the constituent elements described below are arranged in order from the side closer to the combustion chamber, and a gas distribution function is provided inside thereof. A waste incinerator that is equipped with an exhaust heat radiating cylinder that does not interfere.

(I) Shallow upward heating combustion dish, (ii) High-voltage discharge electrode for preventing misfire, (iii) Oil injection nozzle with supply amount controller with injection direction toward the heating combustion dish, (iv) Radiator tube A pipe provided coaxially with, and having a large number of openings formed in its peripheral wall and end face, and for supplying combustion air communicating with the pressurized air supply means into the heat radiating cylinder.

[Action]

The front lid of the incinerator is opened with combustible industrial waste, and the front lid is sealed by filling the combustion air supply pipe from the upper back side of the furnace inside the furnace. At that time, in order to facilitate ignition, it is advisable to pack easily ignitable cardboard, waste paper, oil cloth, etc. near the front lid.

Next, a small amount of kerosene, etc. is supplied to the heating and burning dish provided in the communication part between the furnace and the heat dissipation cylinder, and it is ignited and stably burned, while radiating liquid fuel and further pressurized air from the oil injection nozzle. Supply in the cylinder.

Further, in order to prevent misfire, a voltage is applied to the high-voltage discharge pole to constantly discharge it.

Here, if it is desired to attach an automatic ignition device, if an electric heater is provided on the bottom of the heating and burning dish and the heating dish is preheated, even worse waste oil is automatically ignited. be able to.

Liquid fuels (including those for injection nozzles) to be burned on the heating and burning dish are heavy oil, kerosene, light oil, and other waste oils. Especially when waste oils are used as fuels, doubly incinerate industrial wastes. Is possible.

Thus, when the combustion state of the fuel oil became stable inside the heat radiation tube, the combustion air supply port provided in the incinerator's grate and front lid was opened to ignite the industrial waste packed in the furnace. While monitoring the combustion state of combustibles in the furnace, adjust the amount of air supplied to the furnace and adjust the amount of supply through the combustion air supply pipe to adjust the combustion speed of waste in the furnace. For example, the combustion heat sequentially steams and combusts the combustible waste that has been packed in the interior of the furnace, and the combustion of the waste continues, and the gas has been previously burned and heated. It is guided through the circulation gap to the heat dissipation cylinder side and is heated by touching the jet flame from the injection nozzle, while it is mixed with the pressurized air injected into the cylinder through the openings formed in the peripheral wall. As it rises in the heat dissipation cylinder, it completely burns at high temperature and smokeless Changes in odorless gas is discharged from the heat tube end.

The heated gas contacts the pressurized air at the bottom of the heat radiation cylinder and partially burns, causing itself to generate heat and rise inside the cylinder, where it contacts the next pressurized air and further burns to raise the temperature. Since such an action is repeated while flowing along the combustion air supply pipe wall in the heat radiating cylinder, complete combustion can be achieved by giving an appropriate length to the heat radiating cylinder.

At that time, the openings formed in the peripheral wall are made coarse or small on the side close to the pressurized air supply pipe and dense or large on the side far from the compressed air supply pipe to make the supply air amount uniform in the longitudinal axis direction. , Complete the combustion of gas.

Depending on the type of waste, by installing multiple combustion air supply pipes in the furnace, it is possible to prevent the incinerated materials from sticking to each other and agglomerating to reduce combustion efficiency. Post-processing of the incineration becomes easier.

Of course, at that time, stirring the combustible material on the upper surface of the rostrur with a poker or the like is effective for maintaining the rapid combustion state.

It is also possible to stack and mix different types of waste, such as chemical waste and wood chips, corrugated cardboard or a large amount of agricultural vinyl film, old tires, wood chips, etc., and pack them in the furnace. It is effective in achieving the purpose of incineration.

After the waste that has been packed in the furnace is almost burned, open the front lid and add / inject new industrial waste into the furnace again.
The inserted waste can be continuously processed by spontaneous ignition in the heated combustion chamber.

In the case of fire extinguishing, it is possible to completely extinguish the fire by closing and sealing the passage of the combustion air supplied to the incinerator, and by stopping the supply of oil on the heating combustion plate installed at the base of the heat dissipation cylinder. it can.

The temperature during the burning and burning in the above combustion chamber is around 250 ° to 300 ° C. around the upper portion thereof, so that even if a steel plate is used as the constituent material of the furnace, there is durability.

However, in the vicinity of the jet flame inside the heat sink, 1000 ° -1200 ° C
Due to the high temperature, it is also possible to extend the service life by cooling the body by providing a water jacket or air cooling means with the heat radiating cylinder as a double tube.

As described above, for example, when incinerating waste electric wires coated with rubber or plastic, close the combustion air supply port provided on the opening / closing lid, and minimize the amount of air supplied from the rustle part (to the extent that waste does not extinguish fire). ) And incinerate it with rubber,
Only the plastic material is steamed and carbonized, the copper wire inside is not oxidized, and the carbonized ash of the insulating material can be easily removed from the copper wire.
Reuse copper wire and increase material value.

Charcoal can be produced by charging wood only into a furnace, incinerating by the same method as above, completely steaming, then completely sealing the air supply port and completely extinguishing fire.
