Description

Smokeless, odorless, and dust incinerator

The present invention applies to general waste such as garbage, paper and wood scraps from households and offices due to normal consumer life, industrial waste such as rubber products and plastics that are no longer needed at production factories and construction sites, and many others. The present invention relates to a pollution-free incineration apparatus that prevents emission of pollutant substances such as soot, odors, and dust floating in the exhaust gas in the incinerator when the incinerator is combusted and incinerated.

The Food Recycling Law, which is intended to recycle raw materials such as feed and fertilizer, has been enforced for unsold food, leftover food, or food waste generated in the food manufacturing process. In addition, automobile tires that have become worn out and are no longer used due to problems with safe driving have been developed by the Automobile Recycling Law. Recycling technology has been developed. The current situation is that they are piled up and left for a long time. Also, it is generally prohibited for individuals to incinerate general waste and industrial waste on their own due to the problem of polluting the environment by causing harmful substances such as black smoke, nitrogen oxides and dioxins to be polluted. It has been. Because of these problems, many incinerators have been developed in the past to improve the combustibility of general waste and industrial waste and reduce the discharge of persistent organic chlorine compounds such as dioxins, and have been introduced in many patent publications. ing. For example, in Japanese Patent Laid-Open No. 5-26422, “the furnace body is cooled because the furnace wall is cooled by making the furnace wall into a double casing structure having a space through which low-temperature combustion air or exhaust gas after water washing passes. In addition, by providing a plurality of air jet holes in the inner casing, combustion air is injected into the furnace to improve combustion efficiency and prevent generation of white smoke in the exhaust gas discharged from the chimney. A waste incinerator having a structure is disclosed. Japanese Patent Laid-Open No. 2001-99414 discloses that the outer wall of the first combustion chamber and the combustion gas second combustion chamber, which suppresses the discharge of oxydine by raising the temperature to 800 ° C., kneaded with red clay and water added to the calcined gypsum. A waste incinerator that can withstand high temperatures and easily repair the outer wall of a combustion chamber that has been peeled off by building a metal mesh plate that has been coated and cured with a metal mesh is disclosed. Furthermore, JP 2004-321958 A discloses that, in order to remove the acid gas discharged from the incinerator for municipal waste and industrial waste, the sodium bicarbonate powder added in the exhaust gas flue is brought into contact with the acid gas in the exhaust gas. An incinerator exhaust gas treatment method for reacting and recovering the produced neutralized salt is also disclosed.
None of the waste incinerators and exhaust gas treatment methods described above are superior in that the durability of the furnace body is improved compared to the previous prior art, and that the waste combustibility and exhaust gas treatability are remarkable. Technology. However, the incinerator or incineration method that has been developed to date is an incineration technology that supplies the amount of air necessary for the incinerated product to burn, so that the incineration time is long and the tar contained in the exhaust gas is contained in the inner wall of the incinerator. There was a point that should be markedly improved with respect to the effect of suppressing the scattering of smoke, odors and harmful substances.
This problem has been solved by an incinerator previously filed by the applicants of the present application, as disclosed in Japanese Patent Application Laid-Open No. 2004-245478, “Combustion chamber for burning incinerated material in supercharged state and unexposed in exhaust gas. A small incinerator equipped with a cooling cylinder that rapidly cools the exhaust gas temperature from 800 ° C to 200 ° C on the exhaust gas side of the incinerator main body consisting of a recombustion chamber that raises the combustion gas temperature to 800 ° C or higher dioxin pyrolysis temperature Further, “Japanese Patent Application Laid-Open No. 2008-57906 discloses an incinerator that burns an incinerated product by supplying excess air, and an exhaust gas combustion burner and an exhaust gas extinguishing burner while maintaining the exhaust gas generated in the incinerator at a high temperature. There is a low-pollution incineration processing apparatus that is connected to an exhaust gas cooling tower that burns at a low temperature and further rapidly cools the exhaust gas to a low temperature. The above-mentioned small incinerator and low-pollution incineration equipment developed by the applicant of the present application combusts and incinerates the incinerated object at a supercharged air ratio, so that the waste is completely ashed and the exhaust gas is also smokeless and odorless In addition, since the exhaust gas is rapidly cooled from high temperature to low temperature, generation and resynthesis of dioxins are suppressed, and it is discharged into the atmosphere with low or no pollution. However, in an incinerator with a small incineration volume, when incinerating a large amount of incinerated objects such as long ones on a grate at random or incinerating a combustible assembly with a large volume space such as an empty box The incinerators suddenly collapse during combustion, disturbing the flow of the exhaust gas in the furnace for a moment, and smoke, odors, floating dust and soaring accumulated ash generated by incomplete combustion are part of the exhaust channel. There was concern about the problem of being swept away by the exhaust gas flowing along

JP-A-5-26422 JP 2001-99414 A JP 2004-321958 A Japanese Patent Laid-Open No. 2004-24578 JP 2008-57906 A

In view of the problems as described above, the present inventors have found that smoke and odor generated by incomplete combustion even if the incinerated material causes a collapse of cargo during combustion in an incinerator, floating dust, soaring deposited ash, etc. As a result of various studies for the purpose of providing a pollution-free incinerator (furnace) that is not mixed with the exhaust gas and discharged from the exhaust gas chimney, in addition to the ignition burner for burning the incinerated material in the combustion furnace, the exhaust gas combustion burner It was found that the purpose can be achieved by providing an air supply blower for burning incinerators, a mist nozzle, etc., and controlling these control circuits through a smoke concentration sequencer controller.

The present invention is configured based on the knowledge, and the gist of the present invention is that an exhaust gas collecting outlet is provided on the upper side of the upper chamber separated from the upper and lower chambers by installing a grate in the furnace and opened and closed on the furnace wall.

A furnace equipped with a sequencer controller, and a furnace temperature detection signal obtained by converting the detected temperature of the in-furnace thermometer provided on the upper chamber side of the incinerator into an electrical signal, and the furnace set temperature of the temperature controller converted into an electrical signal The internal temperature setting signal for comparing the internal temperature setting signal is received. The internal temperature deviation signal of the internal temperature sequencer controller and the composite signal connecting the high output signal of the soot concentration sequencer controller described above are received. In the meantime, connect the burner relay controller for burning the incinerator to control the burner burner that injects the amount of fuel required to raise the temperature inside the furnace and completely burn the incinerator and soot. Further, either one of the composite signal obtained by connecting the furnace temperature deviation signal of the furnace temperature sequencer controller described above and the high output signal of the electrical signal transmitted from the smoke concentration sequencer controller described above via the ignition continuation timer. While receiving the signal or both signals, connect the burner relay controller for exhaust gas combustion that controls the burner for exhaust gas combustion that injects the fuel necessary to completely burn the unburned material flowing into the exhaust gas collecting outlet of the incinerator And a relay circuit while receiving either one of the composite signal connecting the high output signal of the smoke concentration sequencer controller and the in-furnace temperature deviation signal of the in-furnace temperature sequencer controller or both of them. The mist nozzle that opens the water supply solenoid valve and injects mist-like water is installed above the upper chamber of the incinerator. It is a smokeless odorless dustless incinerator configured by connecting a control circuit that operates by receiving a proportional control signal of a sensor controller to the above-described exhaust gas cooling air supply blower. Further, the invention having the above-described structure is a smokeless odorless dustless incinerator configured to be connected to an in-furnace air amount adjusting damper of an air supply blower for burning incinerated objects as necessary.

The smokeless, odorless, dustless incinerator of the present invention configured as described above is an incineration object, for example, when two old 12-inch automobile tires that are no longer needed are stacked and incineration is attempted. Even if the phenomenon of cargo collapse occurs, the smoke concentration detection value of the gas discharged from the exhaust gas tower is stable, colorless and smokeless, and dust-free. During this time, the combustion time until the tires were incinerated was completely incinerated in 1 hour. Since old tires, which are generally considered difficult to be incinerated, are incinerated with no smoke, no odor, and no dust, there is no room for doubt of environmental pollution in the incineration of combustible garbage, paper waste and wood waste from homes and offices.
Table 1 shows the measurement and analysis of pollutants such as dioxin concentration and sulfur oxide emission in exhaust gas or incineration ash when industrial waste such as rubber products and plastics that are no longer needed is incinerated with the incinerator of the present invention. Results are shown. The measurement results for all substances are much lower than the legally stipulated values, suggesting pollution-free.

It can be attached accordingly, and its shape and mounting structure are not particularly limited. The smokeless odorless dustless incinerator of the present invention is provided with the exhaust gas cooling tower 12 at the exhaust gas collecting outlet 3 of the incinerator 1 as described above, and further detects the smoke concentration of the exhaust gas at the exhaust gas outlet side of the exhaust gas cooling tower 12. In addition, in order to enable smokeless, odorless, and dustless incineration operations in response to abnormal changes in the exhaust gas caused by the collapse of the incinerated material, which occurred suddenly during the combustion of the incinerated material, The control circuit is configured to supply a gas or air necessary for pollution-free operation such as an air supply blower alone or in combination.
