The present invention relates to an incineration apparatus for incineration of waste such as waste rubber, and more particularly, the combustion air wide-area supply pipe installed in the center of the incineration chamber evenly supplies the combustion air to the entire incineration chamber, thereby dramatically reducing the incineration capacity of the waste. In addition, the combustion gas generated during combustion is smoothly discharged without stagnation in the incineration chamber as it is led upward along the combustion air wide supply pipe, and additional combustion air is supplied to the upper side of the incineration chamber through the auxiliary nozzle pipe. The present invention relates to a waste incineration apparatus which allows the side incineration capacity to be doubled.

In recent years, in the effort to develop alternative energy along with the disposal of waste such as waste tires and waste rubber, it is possible to generate hot water by heating water using high-temperature combustion heat generated during the combustion process of waste and to use it for heating purposes. Was.

However, in the case of using the expensive energy sources such as petroleum and bunker C oil as a combustion source, the waste in the incinerator of the direct heating furnace is continuously incinerated, and hot water is economically generated by generating hot water using the energy generated during combustion. I could not get a problem was followed.

In view of the above-mentioned problems, various types of incineration devices that can be used as energy sources such as hot water or heating by using high-temperature combustion heat generated during combustion as well as incineration of wastes without using oil, which is an expensive energy source, are proposed. It is becoming.

An example of such an incinerator 1 is an incineration chamber with a double jacket so that cooling water flows into the cooling tank 4 between the inner and outer cylinders 2 and 3 for the purpose of fire resistance, as shown in FIGS. (5) is configured, the upper inlet of the incineration chamber (5) is combined with a closed cover (6) for blocking the high-temperature combustion gas is released into the atmosphere during combustion, the bottom of the incineration chamber (5) The forming furnace 7 is coupled to the hinge 8 to allow the incinerated ash to be discharged to the outside through selective opening.

The combustion furnace 7 is divided into a cooling tank 4 through which cooling water flows, and an air tank 10 in which combustion air supplied from a blower is filled through a combustion air supply pipe 9, and the air tank ( The combustion air filled with 10 is injected into the combustion furnace 7 upper portion of the incineration chamber 5 through the plurality of nozzle tubes 11 to burn the waste in the incineration chamber 5.

The high temperature combustion gas generated in the combustion process is introduced into the gas combustor 12 through the exhaust duct 12 and then burned by the flame of the burner, and only hot heat is stored in the state in which various harmful gases are removed. It is supplied to the chamber 13 to heat the hot water through heat exchange with the heat medium or recycle it for heating purposes.

However, such a conventional incinerator 1 is installed such that the nozzle tube 11 for injecting combustion air into the incineration chamber 5 is almost horizontal to the bottom surface of the combustion furnace 7 without protruding upward. Combustion air was injected intensively only on the bottom surface, and thus it could not be uniformly supplied to all areas of the incineration chamber 5.

As a result, the waste located in the lower portion of the incineration chamber 5 not only improves the porosity due to the injection pressure of the combustion air, but also facilitates combustion by smoothly inflowing oxygen. In addition to low porosity, incineration capacity was remarkably reduced because oxygen was not smoothly introduced.

In addition, various harmful gases generated during the combustion process may be moved upwardly along the vertical gas induction pipe 14 installed on the side of the incineration chamber 5 to be partially discharged through the discharge duct 12, Since a larger amount of harmful gas generated is stagnated in the lower part of the incineration chamber 5 without being discharged properly, the interior of the incineration chamber 5 maintains a high pressure so that there is always a risk of explosion. It was to be exposed.

The present invention is to solve the above problems to improve the incineration capacity per unit of time, as well as to smoothly remove the risk of explosion explosion through the smooth discharge of gas, the combustion air wide-area supply pipe via the upper and lower part in the center of the incineration chamber The combustion gas is injected into the wide area while passing through the entire area of the incineration chamber, so that the porosity of the entire waste is improved as well as the oxygen supply is smooth, and the incineration capacity is greatly improved. The main purpose of the invention is to be able to be induced to smoothly discharged.

In addition, another object of the present invention is to form an auxiliary nozzle pipe protruding upward on both sides of the combustion furnace so that the supply of combustion air can be doubled in the relatively weak side portion.

In addition, another object of the present invention is to arrange a plurality of horizontal gas induction pipe horizontally in the incineration chamber at equal intervals so that harmful gas generated in the center portion is guided to the side and then guided to the vertical gas induction pipe smoothly discharged to the top To be.

The configuration of the preferred embodiment for effectively achieving the object of the present invention will be described.

The present invention avoids the conventional practice in which the combustion air for promoting combustion is concentrated and supplied to the lower portion of the incineration chamber (5) and incinerated by being supplied in a wide area inside the incineration chamber (5) through the combustion air wide-area supply pipe (100). At the same time, as well as the ability to improve the harmful gas is led to the combustion air wide-area supply pipe 100 is smoothly discharged to the upper, through the auxiliary nozzle pipe 200 installed on both sides of the combustion furnace (7) combustion air in the weak side portion Is smoothly supplied, the harmful gas generated in the central portion is guided to the vertical gas guide pipe 14 of the side by the horizontal gas guide pipe 300 is smoothly discharged to the top of the characteristic of the invention.

The present invention for achieving the above-mentioned characteristic gist is composed of a double jacket formed with a cooling tank (4) between the inner, outer cylinder (2) (3) as shown in Figure 2 and the sealing cover (6) at the top The combined incineration chamber 5 and the combustion furnace 7 divided into the cooling tank 4 and the air tank 10 in the lower portion of the incineration chamber 5 are coupled to open and close, the air tank 10 In the incineration device (1) is supplied to the combustion air filled in the lower portion of the incineration chamber (5) through a plurality of nozzle tubes (11),

Combustion air wide-area supply pipe 100 is installed so as to pass through the inner upper and lower portions of the incineration chamber (5), evenly through the entire area of the incineration chamber (5), and the combustion furnace (7) It can be seen that the auxiliary nozzle pipe 200 is installed on both sides of the) and the horizontal gas induction pipe 300 is installed horizontally inside the incineration chamber 5 to guide the harmful gas in the side. .

Hereinafter, the present invention having the schematic configuration will be described in more detail.

Combustion air wide-area supply pipe 100 for supplying combustion air to the incineration chamber (5) in a wide area is configured in a concave shape so as to flow again from the lower portion of the incineration chamber (5) through the upper portion, the combustion furnace (7) It is vertically penetrated through the center of the combustion furnace (7) from the outside of the inside and consists of a double pipe having a double structure of the inner and outer tubes (101, 102) so that the combustion air and the cooling water respectively flow in an independent state. .

The inner tube 101 is a passage through which the combustion air for supplying combustion air to the wide area inside the incineration chamber 5 is connected to the air tank 10 and the combustion air branch pipe 103 so that the air tank is connected. Combustion air filled in 10 is smoothly introduced into the inner tube 101 through the combustion air branch pipe 103, while combustion air flowing into the inner tube 101 is radially formed in the plurality of air nozzles 104. Through) is sprayed evenly throughout the incineration chamber (5).

In this case, the air nozzle 104 is installed to be inclined upwardly so as to smoothly inject combustion air to the upper side, and in general, the waste is concentrated on the lower side than the upper side in consideration of intensive combustion toward the lower portion of the incineration chamber 5. Since the air nozzle 104 is installed in a large number so that the upper and lower installation intervals gradually become narrower toward the lower side so that a larger amount of combustion air is supplied, it is possible to more smoothly supply the combustion air to the entire waste.

In addition, the combustion air injected from the combustion air supplied through the combustion air branch pipe 103 moves upward, and the combustion air injected from the discharge side moving downward after passing through the interior of the incineration chamber 5 collide with each other. As shown in FIG. 6, the air nozzles 104 installed on the inflow side and the outflow side are arranged in a staggered manner.

In addition, the combustion air branch pipe 103 is provided with an air valve 105 for artificially controlling the supply amount of the combustion air supplied to the inner tube 101, in particular, when the waste is mostly incinerated and the remaining amount is not much remaining Even if the valve 105 is opened to slightly increase the supply of combustion air, incineration can be completed in a shorter time.

The exterior 102 installed on the outside of the inner tube 101 allows the coolant to flow to the outside of the inner tube 101 so that the combustion air wide-area supply pipe 100 passes through the incineration chamber 5 in a high temperature state. As it does, it does not bend or melt down.

The coolant is introduced into the space between the inner and outer tubes 101 and 102 through the coolant pipe 106 and cools the combustion air wide-area supply pipe 100 while passing through the inside of the incineration chamber 5 and then recovers the coolant. It can be introduced into the cooling tank (4) through the pipe (107).

In the present invention, the detailed configuration for inflow and outflow of the cooling water into the cooling tank 4 between the inner and outer cylinders 2 and 3 and the cooling tank 4 formed in the combustion furnace 7 is omitted. It is a basic matter that the cooling water is configured such that the cooling water can be circulated without being stagnant, such as the wide area supply pipe 100.

On the other hand, the auxiliary nozzle pipe 200 for intensively supplying the combustion air to the side portion where the supply amount of combustion air is relatively weak compared to the central portion of the incineration chamber (5) is manufactured to have a larger size than the general nozzle pipe (11) It is installed to protrude upward through the cooling tank (4) on both sides of the combustion furnace (7) and the inside is in communication with the air tank 10, the combustion air is smoothly supplied to the upper side of the side portion to further double the combustion capacity. It becomes possible.

In addition, a plurality of horizontal gas induction pipes 300 for inducing various harmful gases generated in the center of the incineration chamber 5 to the side portion is installed horizontally inside the incineration chamber 5, but the coolant flow to prevent overheating Both sides are installed to be in communication with the cooling tank 4 between the inner and outer cylinders (2) and (3).

Therefore, the harmful gas generated in the center is guided to the side portion along the horizontal gas induction pipe 300 and guided to the vertical gas induction pipe 14 installed vertically on the side part, and then upwards along the vertical gas induction pipe 14. It can be easily discharged.

The horizontal gas induction pipe 300 guides the harmful gas to the side to guide the vertical gas induction pipe 14 as well as supports a relatively large size of waste as a plurality of consecutively installed at equal intervals. Combining the role of grate can be more smooth combustion.

The vertical gas induction pipe 14 is the same as the horizontal gas induction pipe 300, the upper and lower parts are in communication with the cooling tank 4 is not overheated as the cooling water flows inside.

That is, the vertical gas induction pipe 14 effectively guides the harmful gas generated during combustion together with the horizontal gas induction pipe 300 so as to be smoothly discharged to the outside without stagnation in the incineration chamber 5. By doing so, the concerns of explosions due to the gas congestion are alleviated.

The incineration process of waste according to the present invention having such a configuration will be described.

First, lift the upper airtight cover 6 to the top by using a towing means such as a winch, inject waste into the inside, and open an ignition door (not shown in the drawing) installed at a predetermined portion of the outer surface of the incineration chamber 5. Ignition in the incineration chamber (5).

If the waste is ignited, combustion air is supplied to the air tank 10 through the combustion air supply pipe 9, and the combustion air filled in the air tank 10 is basically a combustion furnace through a plurality of nozzle pipes 11. By intensively supplying combustion air under (7), the waste is burned on its own without a separate heat source.

At this time, a part of the combustion air filled in the air tank 10 is supplied branched to the combustion air wide-area supply pipe 100, the supplied combustion air passes through the air nozzle 104 while passing through the upper and lower portions of the incineration chamber (5). Through the smooth supply of the combustion air to the entire waste through the gap between the waste is further promoted combustion, as well as harmful gases generated during the combustion process is led to the upper portion along the combustion air wide-area supply pipe 100 and discharged smoothly do.

In addition, the combustion air is additionally supplied to the upper side of the side through the auxiliary nozzle pipe 200 installed in the side of the combustion furnace 7 to improve the combustion efficiency of the side portion was weak.

In addition, a part of the harmful gas generated in the center during the combustion process is guided upward along the combustion air wide-area supply pipe (100), as well as the residual gas is guided laterally by the horizontal gas guide pipe (300) and then the vertical gas guide pipe Since it is smoothly discharged to the upper side through (14), there is no fear of explosion accident due to the stagnation of gas.

According to the present invention, as the combustion air is uniformly supplied to the entire waste along the upper and lower portions of the combustion air wide supply pipe installed in the incineration chamber, the incineration capacity per unit time is significantly improved as well as the combustion air wide supply pipe. Accordingly, the harmful gas generated during combustion can be smoothly guided to the top and discharged.

In addition, by additionally supplying combustion air to the upper side of the side by the auxiliary nozzle pipes installed on both sides of the combustion furnace, the weak combustion capacity of the side is doubled.

In addition, by the horizontal gas guide pipe installed in the incineration chamber, the harmful gas generated in the center is guided to the side smoothly and then discharged to the upper side along the vertical gas guide pipe to prevent the explosion of the explosion due to the gas in the incineration chamber. Will be effective.
