JP5625205B2 - Smokeless, odorless, and dust incinerator - Google Patents

Description

  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, Japanese Patent Laid-Open No. 5-26422 discloses that a furnace wall having a double casing structure having a space through which low-temperature combustion air or exhaust gas after water washing passes is used to cool the furnace wall, thereby damaging the furnace body. In addition, by providing a plurality of air ejection holes in the inner casing, the combustion air is introduced into the furnace, improving the combustion efficiency and preventing the generation of white smoke in the exhaust gas discharged from the chimney "Waste incinerator". 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, odor and harmful substances.

An incinerator filed by the present applicants has solved such problems, as disclosed in Japanese Patent Application Laid-Open No. 2004-245478, “Combustion chamber for incineration of incinerated material in supercharged state and unburned gas in exhaust gas” A small incinerator in which a cooling cylinder for rapidly cooling the exhaust gas temperature from 800 ° C. to 200 ° C. is installed on the exhaust gas side of the incinerator body consisting of a recombustion chamber that raises the temperature to a pyrolysis temperature of dioxins of 800 ° C. or higher. Furthermore, in Japanese Patent Application Laid-Open No. 2008-57906, “incinerators for burning input incineration products by supplying excess air, and combustion with an exhaust gas combustion burner and an exhaust gas extinguishing burner while maintaining the exhaust gas generated in the incinerator at a high temperature. Furthermore, there is a low-pollution incineration processing apparatus in which an exhaust gas cooling tower that rapidly cools exhaust gas to a low temperature is connected, and an exhaust gas septic tank is provided as necessary to connect an exhaust gas chimney. 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 and discharged from the chimney.
