CONSTITUTION:Steel doors (a) and (a') are opened and several waste tires are charged through a feeding hole 3 into a combustion chamber F of a furnace 1 and ignited. Gas evolved when the waste tires are burned in the combustion chamber F, is discharged through a smoke outlet 4 of a rear wall A', while a heavy soln. falls from a permeation floor 5, reaches stream outlets 8 and 8' along the inclined surface of a bottom wall 6 and is withdrawn out of the furnace and then recovered through an outer passage. The gas passing through the smoke outlet 4 is recovered on its way through a duct 11 as a carbonized material such as carbon black into a bag for recovery.

Description

[Detailed Description of the Invention] This invention relates to a method and apparatus for incinerating waste automobile tires, synthetic resin waste, etc. and recovering recycled materials such as solvents, fuels, and charred materials from the incineration. It is possible to efficiently dispose of waste tires from automobiles, etc., which generate a large amount of waste, and also to save energy by recycling the waste tires.
The aim is to recover it at low cost and without pollution.

The amount of automobile and other tires that are collected as scrap tires every year is enormous, and it is now an urgent matter to dispose of them or utilize them for recycling, but there are effective measures to achieve this. There's not enough about it. Attempts have been made to use some of them directly as roadbed material for road construction or as fishing reefs, but once used, these materials are durable and can be used to absorb the accumulated amount year after year. Conventional methods such as freeze-shredding and pyrolysis, which are not the best way to use waste as recycled resources, require large-scale equipment and machinery. The investment amount was large and it was not easily available to the general public.

The present invention is a method and apparatus for processing waste tires, etc., devised in view of such circumstances, and will be described in detail below.

First, the apparatus of the present invention will be described with reference to the drawings. FIG. 1 is a front view of the entire incinerator (1) of this apparatus, and FIG. 2 is a side view thereof. This incinerator (1
) is on the ground (E) with a combustion chamber (F
) The furnace material (2) is made of sandstone blocks (for example, Oya stone), or clay material mixed with straw shavings. It is appropriate to use construction materials.

It has two iron doors on the front wall (A) and an input port (3) that can be opened and closed at (a)', making up the four surrounding walls, the upper and lower ceiling walls, and the four bottom walls. Approximately 15cm thick
1 External width 1m, height 1.5m, depth 1.35m.

The total used area of the furnace is approximately 3.3% square meter, the total area of the site is approximately 99 square meters], and above the rear wall (A') there is a smoke port (4) equipped with a rear wall shutter (b) that opens and closes. In the lower part of the combustion chamber ('F'), there is a permeation plate (5) that allows the solvent and fuel recovered in the form of a solution to pass through and drip. A steel plate with many long holes arranged in parallel] is attached to the bottom wall (6) with a space (7) interposed therebetween.

This bottom wall (6) is a sloped surface that is higher at the back than the input port ('5), and there is a flow port (8) provided at the bottom of the front wall (A).
, (8) From 9, the solution-like recovered material is taken out of the furnace. That is, as shown in Fig. 3, the flow ports (8), (8)' are connected to the external flow paths (9), (
9)', and they collect in a collection tank (10).

Incidentally, the inlets of the flow ports (8) and (8)' are provided with flow port shutters (c) and (c)' that open and close them.

Figure 4 shows the rear wall (A') of this incinerator (1), with a duct (11) attached to the smoke port (4) mentioned above in Figure 2. In the lower surface of this duct (11), there is a collection hole (13) into which a collection bag (12) is attached in order to collect the carbide (carbon black, etc.) passing through the duct (11).
), (13)'... is provided, and a collection bag (12) is hung from it to collect the carbide accumulated there.

A butterfly plate is attached to collect the sulfur content that adheres to it, and finally unnecessary gas is thrown into the water to saturate it and then discharged to the outside air, making it pollution-free. (14) is a duct installed everywhere (11) It is the support of

Next, we will talk about the method of incinerating waste tires and the method of recovering the recovered materials using the apparatus of this invention. Open the iron door (al, (a)'), throw in the scrap tires individually or cut into several pieces for large size tires, and first ignite. Typically, one stick is added every 1 to 2 minutes, so that 2 to 3 sticks are burning in the furnace at all times.

The temperature inside the furnace will be 500 to 600°C, and in this way it is possible to burn about 200 to 500 pieces per day (24 hours).

When waste tires are incinerated in this combustion chamber (F), the gas produced by combustion is discharged through the smoke port (4) on the rear wall (A'), while the heavy solution is removed from the permeation plate ( 5) and travels down the slope of the bottom wall (6) to the outlet (8).
(8)' and is discharged outside the furnace into an external flow path (9).

(9)' is recovered. The gas that has passed through the smoke port (4) is collected as a carbide (carbon blank, etc.) into a collection bag (12) while passing through the duct (11). It should be noted that the carbon black collected in the collection bag (12) is of higher quality as it is further along the duct 1-(11).

The higher the combustion temperature in the furnace, the more the former will be emitted, and the lower the temperature, the more the latter will be emitted.
The temperature inside the furnace can be adjusted according to the purpose of collecting them.
Along with the closed iron doors (a) and (a)', especially the smoke vent (
4) Smoke Roshanota (b), outlet (8), (81
By closing the flow port shutters (c) and ((), the inside of the furnace becomes a dry distillation state. This allows the temperature inside the furnace to be easily lowered, and the combustion gas Emissions can also be suppressed. Wire materials and residual adhesion-resistant carbides present in waste tires can be ejected whenever the iron doors (a) and (a)' are opened.

Now, by the method of this invention, the above-mentioned furnace temperature is 500~6.
The weight percentages of the recovered materials when one scrap tire put in at 00°C burns and melts in 3 minutes are as follows: Gaseous body 7% Recovered sulfur content 5% Solution content (solvent, fuel) 35% Carbide 45% Wire 8 %, solution content is 20-40%, carbide content is 40-60%
It is possible to collect changes within the range of .

Further, among the above-mentioned carbides, 30% of carbon blanks can be collected, and the remainder is carbide that is resistant to residual accumulation. This is used for construction panels, etc.

Figure 6 shows an example in which six incinerators are installed in parallel, with three incinerators (1)' arranged in parallel on the - side, three incinerators (1)'' arranged symmetrically, A flue (15) was provided in the center in parallel on the other side. (16) is the inlet of this flue (15), and (17) is its outlet. As a gas outlet corresponding to 4), the flue (
If the upper part of each rear wall (A') facing 15) is left open, it will serve as a smoke port.

Now, waste tires are fed into the incinerators (1)', (1)'' through the inlet (3) and incinerated as described above.The gas collects in the central flue (15) and flows through the outlet (17). The solution is collected outside the furnace from below each front wall (A) in the same manner as in the first illustrated example, and collected in one place.

In addition, the central flue (15) has a temperature of 50% as the temperature inside this flue.
As fuel for maintaining the temperature between 0 and 600°C, waste tires are also introduced from the inlet (15) at a rate of one tire every two minutes.

According to actual examples, the total area for these six units is around 27 square meters, which is easily 3,000 square meters per day (24 hours).
~5,000 waste tires can be incinerated.

So it is discharged into quicklime emulsion and used as artificial plaster to prevent pollution.

According to the method and apparatus of the present invention, waste tires and the like can be incinerated and dry distilled freely, so that waste tires and the like can be easily processed and recycled materials can be collected. The inside of the furnace burns in an almost sealed state, so it is easy to maintain and adjust the temperature.Furthermore, the inner wall of the furnace material that is in contact with it becomes porcelain due to the combustion inside the furnace, increasing its strength and fire resistance. It also has sufficient resistance to gas pressure and chemical corrosion. .

Further, dry distillation suppresses the generated gas, and all the gas flows through the smoke port and duct, where it becomes carbide,
After collecting the sulfur content, it is dumped into water and discharged without causing any pollution.

In addition, since the recycled materials are collected by incinerating the waste tires themselves, no energy is required to expel the recycled materials. This is a truly economical and useful invention as a technology for quickly processing a large amount of waste tires that accumulate year after year using space and small-scale equipment, and recovering recycled materials.

Note that this method and apparatus can naturally be applied to the treatment of other synthetic resin waste materials.
