Description

  The present invention is an incinerator for waste oil / waste tires, and more specifically, a very simple device that uses no power. The present invention relates to an incinerator for waste oil, waste tires, and the like that can naturally burn waste oil and the like, and that can effectively use the combustion heat.

  Disposal of waste oil generated from vehicles, ships, factories, kitchens, etc. is generally performed by incineration. When incinerating waste oil, black smoke and harmful substances are likely to be generated due to incomplete combustion, and various types of waste oil incinerators have been proposed to prevent the generation (for example, JP-A-2003-336822). JP, 2002-22135, JP 2001-56112, JP 2000-74348, etc.). Most of them are relatively large ones equipped with an air supply device in the combustion chamber, and there are considerable equipment costs and operating costs, so for small-scale factories and facilities, or for private equipment such as ordinary households Not suitable.

  Recently, biodiesel fuel (BDF) has been attracting attention as a carbon-neutral alternative to light oil, but glycerin is produced as a by-product of about 10 percent of raw oil and fat. Normally, this glycerin is left as it is because it cannot contain an effective application because it contains a catalyst, unconverted fatty acid, etc., and there is a need for an effective means for its treatment. It has been.

  In addition, waste tires are often treated by incineration or carbonization carbonization. In that case, harmful black smoke and bad odor are generated. Therefore, the apparatus becomes complicated and large, and the installation cost increases. Therefore, the apparatus is not suitable for installation in a small factory or facility.

  As described above, all of the conventionally proposed waste oil incinerators are relatively large and complex equipped with an air supply device, and there are problems in terms of cost for providing them for private facilities. It is not an effective means of glycerin treatment, which has recently become a problem. And furthermore, they are not suitable for incineration of waste tires.

  Therefore, the present invention is a small and simple configuration that does not use power such as an air supply mechanism by a fan, can be supplied at a relatively low cost, and can completely burn waste tires and waste oil. It is suitable for use in private facilities such as ordinary households, for auxiliary heating in agricultural houses, and for emergency facilities in the event of a disaster, and also effective for the treatment of glycerin, It is another object of the present invention to provide an incinerator for natural combustion type waste oil / waste tires, etc., capable of effectively utilizing heat generated by combustion.

  The invention according to claim 1 for solving the above-mentioned problems is a combustion chamber for introducing waste tires, waste oil and other incinerated materials, an ascending cylinder and a descending cylinder standing on the combustion chamber, and the ascending cylinder And a vortex chamber that is installed on the descending cylinder and communicates with the combustion chamber via the ascending cylinder and the descending cylinder, and a plurality of air intake ports for introducing outside air are formed in the ascending cylinder The rising cylinder is arranged so that its upper end opens at the center of the bottom surface of the vortex chamber, and the lowering cylinder is made smaller in diameter than the rising cylinder, and its upper end is located at the peripheral edge of the bottom surface of the vortex chamber. An incinerator for waste oil / waste tires, etc., characterized in that it is disposed so as to open, and further, an exhaust pipe is installed in the vortex chamber.

  Preferably, the air suction port formed in the rising cylinder has a plurality of rows of holes formed at regular intervals in the vertical direction, and the air suction ports in the adjacent hole rows are shifted in the vertical direction. Thus, the generation of the vortex of the combustion gas rising in the rising cylinder is promoted. The combustion chamber may be sized to accommodate a tire.

  The vortex chamber may be housed in a heat exchange tank constituting a geothermal heating system or other hot water circulation system.

  The incinerator for waste oil and waste tires according to the present invention can be supplied with a simple structure and at a low price, and can be automatically turned on without using any power by simply igniting by putting waste tires or waste oil into the combustion chamber. It is very useful to be able to use only the combustion gas that has been completely burned and detoxified, and to make effective use of the heat of combustion, and for private facilities such as small factories and general households. It is suitable for use as an auxiliary heating facility for agricultural houses, and as an emergency facility for disasters.

  Further, in the device according to the second aspect, since the generation of the vortex in the ascending cylinder is satisfactorily performed, there is an effect of promoting the complete combustion of the combustion products such as waste oil and waste tires.

It is a longitudinal cross-sectional view which shows the effect | action of this invention. It is a perspective view of other embodiments of the present invention. It is the sectional view on the AA line in FIG. It is the BB sectional view taken on the line in FIG. It is a perspective view which shows the example of application to the other apparatus of this invention.

  A preferred embodiment for carrying out the present invention will be described with reference to the accompanying drawings. The apparatus according to the present invention is an incineration apparatus for incineration products such as waste tires and waste oil, and those shown in FIGS. 1 to 3 are configured for tire incineration, and those shown in FIGS. It is configured for waste oil incineration. In the case of other incinerators, they shall have the corresponding size and structure.

  The apparatus according to the present invention configured for incineration of tires shown in FIGS. 1 to 3 includes a combustion chamber 1 into which a waste tire 15 to be subjected to combustion treatment is charged, and an ascending cylinder 2 and a descending cylinder standing on the combustion chamber 1. 4 and a vortex chamber 3 installed on the ascending cylinder 2 and the descending cylinder 4 and brought into communication with the combustion chamber 1 via the ascending cylinder 2 and the descending cylinder 4.

  The combustion chamber 1 is a container having a plurality of legs 6, and a charging port 7 for charging incineration material is formed on a side surface or an upper surface. In the example shown in FIGS. 1 to 3, the combustion chamber 1 is sized to accommodate one or several waste tires 15, and the entire side surface thereof is opened to serve as the inlet 7. Then, an opening / closing lid 8 with a handle 9 for opening and closing the insertion port 7 is attached. Moreover, although not shown in figure, the combustion chamber 1 is appropriately provided with an air inlet 10 capable of adjusting the air introduction amount (see an embodiment for waste oil described later).

  The ascending cylinder 2 is usually erected at the center of the upper surface of the combustion chamber 1. Since the rising cylinder 2 is for raising a flame, it is sufficiently wide in diameter, and a large number of intake holes 11 and 11a are formed in its peripheral surface. Preferably, the intake holes 11 and 11a are provided by forming, for example, six rows of holes arranged in a vertical row at appropriate intervals. The positions of the intake holes 11 and 11a are shifted by a half pitch in the vertical direction between adjacent hole rows, that is, each intake hole 11 in a row is positioned between the intake holes 11a in the adjacent hole rows. Is arranged.

  The upper end of the rising cylinder 2 is connected to the center of the bottom surface of the vortex chamber 3 so as to communicate with the vortex chamber 3 disposed thereon. The vortex chamber 3 has a cylindrical shape considerably larger in diameter than the rising cylinder 2. Further, the descending cylinder 4 is also opened at the bottom surface of the vortex chamber 3 so as to communicate with the vortex chamber 3 disposed on the lower cylinder 4. Is done. The descending cylinder 4 has a smaller diameter than the ascending cylinder 2 and is usually provided by one. Although two pipes are shown in the figure, one of them is a descending cylinder 4 and the other is a mere support column 12, which is not in communication with the combustion chamber 1 and the vortex chamber 3.

  The exhaust cylinder 5 is installed at the center of the upper surface of the vortex chamber 3 in the illustrated example, but may be provided on the side surface. In addition, the exhaust pipe 5 may be bent horizontally as shown in FIGS. 1 to 3 or may be formed straight as shown in FIGS. 5 to 7.

  In order to use the incinerator for waste oil, waste tires and the like according to the present invention having the above-described configuration, first, the opening / closing lid 8 is opened, and the waste tire 15 to be incinerated is pushed into the combustion chamber 1 from the inlet 7. Then, ignition is performed by appropriately sprinkling fuel oil or the like, and the open / close lid 8 is closed. Thus, the waste tire 15 is combusted, and its flame (combustion gas) rises in the rising cylinder 2, and the tip of the flame reaches the vortex chamber 3.

  Along with the rise of the combustion gas, a negative pressure is generated in the ascending cylinder 2, whereby outside air is sucked from the intake holes 11 and 11 a. At this time, if the positions of the intake holes 11 and 11a in the adjacent hole rows are shifted, vortices are likely to occur in the ascending cylinder 2 due to the sucked outside air, and the contact efficiency between the rising combustion gas and air is increased. Thus, complete combustion of the waste tire 15 is promoted.

  The complete combustion gas a and the incomplete combustion gas b rise while swirling and flow into the swirl chamber 3, and swirl in the swirl chamber 3. At that time, the incomplete combustion gas b having a specific gravity larger than that of the complete combustion gas a moves to the outer peripheral side and further to the lower side due to the specific gravity difference. The incomplete combustion gas b escapes into the descending cylinder 4 by receiving the internal pressure of the vortex chamber 3 that is increased by the combustion gas c that rises continuously, and descends in the descending cylinder 4 to enter the combustion chamber 1. Return to, for re-combustion. The complete combustion gas a having a small specific gravity collected in the upper part or the center of the vortex chamber 3, that is, the harmless exhaust gas, is exhausted through the exhaust cylinder 5.

  The above operation is automatically performed until the waste tire 15 in the combustion chamber 1 burns out and the fire power decreases without supplying air by the power of a fan or the like. As described above, the device according to the present invention has a very simple configuration, and simply injects an incinerated material into the combustion chamber and ignites it, and then completely burns it without using any power and makes it harmless. Since only gas can be discharged, it is suitable for small-scale factories and facilities, or private facilities for general households.

  The apparatus according to the present invention configured for waste oil incineration shown in FIGS. 4 to 6 is also composed of a combustion chamber 1, an ascending cylinder 2, a descending cylinder 4 and a vortex chamber 3, similar to the apparatus for incineration of waste tires. A number of intake holes 11 and 11a are formed in the peripheral surface of the cylinder 2 in the same manner as in the above embodiment. However, the inlet 7 in this case is provided on the upper surface of the combustion chamber 1. 4 to 6, the same reference numerals as those in FIGS. 1 to 3 indicate the same configuration.

  In the case of this embodiment as well, the same effect as in the above embodiment occurs, and the outside air sucked from the intake holes 11 and 11a causes a vortex in the ascending cylinder 2 to increase the contact efficiency between the combustion gas and the air, thereby reducing the waste oil. Complete combustion is promoted. In the vortex chamber 3, the complete combustion gas a and the incomplete combustion gas b are naturally separated by the difference in specific gravity, and the incomplete combustion gas b returns to the combustion chamber 1 through the descending cylinder 4 and is recombusted. The complete combustion gas a having a small specific gravity collected in the upper part or the central part of the vortex chamber 3 is discharged through the exhaust pipe 5.

  In addition, the incinerator for waste oil and waste tires according to the present invention can be used not only independently, but also as a heat source for, for example, an auxiliary heating device for an agricultural house or a geothermal heating system. FIG. 7 shows an example in which this apparatus is used in a geothermal heating system, and a heat exchange tank 18 is disposed so as to surround the vortex chamber 3. The heat exchange tank 18 is a tank covered with a heat insulating material and filled with an antifreeze liquid 19, and the filled antifreeze liquid 19 is heated there, then pumped out by a pump 20, and stored in a warm liquid tank 21. Then, the antifreeze liquid 19 stored in the warm liquid tank 21 is pumped out by a pump 22 and sent out into a heating pipe 23 disposed in the ground of the greenhouse. Thus, the ground is warmed by the heating pipe 23.

  As described above, the device according to the present invention is compact in its entirety and simple in configuration. In any of the embodiments, no power is required, and incinerated products such as waste tires and waste oil are completely burned by natural force. In addition, because it is easy to build a system to obtain hot water and hot air using the combustion heat, it can be used as a waste tire / oil incinerator in small factories and households, and in agricultural houses. It is suitable for use in geothermal heating and auxiliary heating equipment in Japan, or as emergency equipment in the event of a disaster.

  Although the invention has been described in some detail with respect to its most preferred embodiment, it will be apparent that a wide variety of different embodiments can be constructed without departing from the spirit and scope of the invention. It is not restricted to the specific embodiment other than limiting in.
