Abstract

An auxiliary fuel from a burner is mixed with a suitable amount of air and the mixture is uniformly distributed by spiral air currents over a material to be burnt, so that a high temperature region at 800?C or above is instantly formed immediately after ignition. Further, the lateral surface around the hearth bottom has a porous type blower attached thereto for complete combustion of the material, so that the ash is very small in amount. Further, activated oxygen-removed water covers the furnace wall, the latter having a mechanism for preventing degradation of the combustion device. Further, chloride-removed water is changed into high temperature vapor by the heat of combustion, and the vapor is radiated to the atmosphere and mixed with carbon dioxide and acidic gases discharged from a chimney, whereby these are decomposed to prevent atmospheric pollution. These procedures suppress PCDDs and make it possible to provide a combustion device of reduced size that does not require a cooling system, etc.

Description Combustion device for carbon dioxide and dioxin suppression

The present invention relates to the waste combustion and incineration technology in the environmental field, in which toxic dioxin and coblanar PCBs are suppressed in the exhaust gas, and carbon dioxide and acid gas are suppressed by the ionization effect of high-temperature steam from the atmosphere. For the mechanism to be used, a rapid rise to 800 ° C at the same time as ignition, a mechanism that does not lower the combustion temperature even when intermittently injecting combustibles, a dioxin that is toxic to ash after combustion ゃ Coplanar PCB And the amount of ash is very small. The present invention relates to a combustion device having a long life by suppressing thermal deterioration and acid deterioration of the device due to high temperature combustion. Background art

Conventionally, a so-called single-stroke all-in-one combustion device has performed forced combustion using air and auxiliary fuel. However, good combustion was not possible because the air volume was too large and the combustion material was not evenly distributed. For this reason, primary combustion, secondary combustion, and tertiary combustion produced smoke, and the exhaust gas and the ash after combustion contained toxic dioxins. In addition, it took time for the combustion temperature to rise to 800 after ignition, and in order to maintain the combustion temperature, combustion by continuous injection was required. In recent years, filters such as cooling devices and bag filters and smoke suppression devices have been installed, and the entire combustion device has become large, and its control requires complicated electrical systems and mechanisms. This resulted in a large financial burden for equipment costs and maintenance. In addition, since the combustion is not good, the amount of ash after combustion is extremely large at nearly 20% of the input weight of the combustion, and it is difficult to secure landfills, which causes pollution of soil and groundwater in the suburbs. Awake You. Furthermore, there is a lack of awareness and consideration for the recovery of combustion heat, a short service life of the equipment due to high heat degradation and acid degradation, and a lack of awareness of carbon dioxide and acid gas suppression. I'm doing it.

Therefore, the present invention solves such problems with the simplest mechanism, changes the theory of combustion technology, provides a combustion device with a small economic burden and a long life, and conserves the global environment. It aims to contribute to the preservation of the local environment. Disclosure of the invention

According to the present invention, the combustion chamber has a cylindrical structure using a metal material, and a water tank is formed around the structure to fill the combustion chamber with water. The appropriate amount of air and auxiliary fuel from the five-stage blower is placed in a spiral airflow to spread the combustion evenly, and a high temperature zone of 800 or more is created instantaneously from ignition. Simple cyclone and stack are effectively arranged to keep the pressure in the combustion chamber at an appropriate level. As a result, good speed combustion can be achieved. The combustion of organic matter does not produce methane. It does not lead to the production of toxic dioxin-coplanar PCB. In addition, in the combustion of chemically synthesized substances, the benzene ring is cut off by uniform high-temperature combustion of 800 ° C or more, and no toxic dioxin / cobraner PCB is generated. <Also, the bottom of the hearth A blower is placed on the side to supply auxiliary fuel and burn off the combustion material at the bottom of the hearth, making the amount of ash small and harmless and safe.

Further, in the present invention, even when intermittently charged, the mechanism action of the air curtain occurs due to the high-temperature spiral airflow, and the combustion temperature does not decrease.

In addition, the present invention removes active oxygen by increasing the molecular density of water by attaching a permanent magnet to the water supply pipe in a three-stage structure, and also suppresses the generation of the active oxygen. It has a mechanism to prevent deterioration and extends its life. Furthermore, a filter containing activated carbon is installed in the water supply pipe in a two-stage structure, and it is attached and removed by chlorine. A plurality of vapor holes arranged near the cylinder radiate into the atmosphere, and use the phenomenon of ionization reaction in the atmosphere with carbon dioxide or acid gas in the exhaust gas to make it ionize, thereby reducing air pollution. Suppress. (Same as the phenomenon during rain.)

Heat deterioration prevention of the furnace wall due to high temperature combustion is inhibited in the this tensioning water to the furnace wall _((empty kettle cook the same.) Further, Ri by the hot water supply child in the recovery of the combustion heat, Generates economic and environmental benefits.

FIG. 1 is a front view of a preferred combustion device according to the present invention, and FIG. 2 is a side view. FIG. 3 is a drawing showing that a high-temperature combustion zone of 800 or more is formed by injection of auxiliary fuel from a five-stage blower and a burner. FIG. 4 is a drawing showing a state in which gas discharged from an exhaust stack and steam radiated from a plurality of steam holes are mixed in the atmosphere to cause an ionization phenomenon. BEST MODE FOR CARRYING OUT THE INVENTION

In order to explain the present invention in more detail, this will be described with reference to the accompanying drawings. FIG. 1 and FIG. 2 show the simplest and ideal cross sections according to the present invention. Combustion chamber a is made of metal material and has a cylindrical structure, around which a water tank b is created to fill with water. The blowers that blow air into the furnace are arranged in a 5-stage c on the side of the combustion chamber, and have valves cl to c5 to adjust the amount of air to be blown to each. In addition, a perforated blower d is placed on the bottom side surface in the hearth. In addition, the injection nozzle e of the burner that supplies auxiliary fuel is positioned at a position where the height and the injection angle are evenly distributed over the combustion products at the bottom of the hearth. Attach a three-stage permanent magnet g to the water supply pipe を to increase the molecular density of water to remove active oxygen, and attach activated carbon h in a two-stage filter structure to attach chlorine. Removed to prevent and suppress high heat deterioration and acid deterioration of combustion equipment Mechanism.

Fig. 3 shows that the airflow blown by the blower c has a spiral shape i, and the auxiliary fuel spreads uniformly on the top of the combustion material on its orbit, and the combustion material is good. Provides uniform surface combustion. In the heated combustion chamber, the volume of the blown air is nearly four times, and the pressure in the combustion chamber rises. As a result, a straight updraft toward exhaust stack j will occur, but in order to suppress this, the effective arrangement of the simple cyclone k and the position of the exhaust stack j will be properly determined. The spiral airflow trajectory i, which has various functions, is protected. Then, the upper part of the combustion chamber becomes a high temperature zone 1 of 800 ° C or more instantaneously from the ignition. The passage of gas after combustion in the high-temperature zone 1 takes time, and the generation of swoosh fly ash is suppressed. As a result, the exhaust gas becomes smokeless and odorless. With speed combustion based on them, methane is not generated by the combustion of organic substances, and no toxic dioxin / coplana-PCB is generated. In addition, in the combustion of a chemically synthesized substance, its benzene ring is cut off by uniform high-temperature combustion at 800 ° C or more, and does not lead to the production of toxic dioxin-cobraner PCB. Then, the combustion products at the bottom of the hearth can burn the input combustion products to the area of atoms and molecules by the mechanical action of the perforated blower 1d arranged on the bottom side of the hearth. The amount of subsequent ash can be made extremely small and harmless and safe.

FIG. 4 is a drawing showing a state in which the gas j1 discharged from the exhaust stack j and the steam ml radiated from the plurality of steam holes m are mixed in the atmosphere to produce an ionization phenomenon. The ionization phenomenon of carbon dioxide emitted by complete combustion is represented by the following chemical formula.

C 0 ₂ (carbon dioxide) + H ₂ 0 (high-temperature steam) 1 H ₂ C 0 3 (carbonic acid) H 2 C 0 3 (carbonic acid) → H + + HC 0 ₃ — (bicarbonate ion)

HC 0 3-+ H 2 0 (high temperature steam) → H ₂ C 0 ₃ + OH— (alkali ion) This is a decrease in + ions (contaminated air is charged to +) in the atmosphere during rainfall. And the same phenomenon as the increase of one ion.

The causes of atmospheric acidification and acid rain include nitrogen oxides and hydrogen chloride. As shown in the above-mentioned ionization chemical reaction formula, the suppression reaction occurs due to the generation of OH— (alkali ions). Industrial applicability

As described above, the combustion apparatus according to the present invention has the simplest mechanical arrangement of the characteristics and laws of nature, and uses the maximum effect of each action to produce highly toxic substances contained in exhaust gas and incinerated ash. The formation of dioxin-cobraner PCBs is suppressed, and carbon dioxide and acid gases are ionized by the ionization reaction, forming a mechanism that suppresses air pollution. And trace amounts of incineration ash are safe and non-polluting, and can be returned to the natural circulation by dispersing them in the soil of each garden without the need for landfills. In addition, it has a mechanism to prevent and suppress high heat deterioration and acid deterioration that determine the life of the combustion device, and has a function to recover combustion heat and supply hot water. Combustion devices are smaller and more economical because they do not require large and expensive cooling devices or bag filters. Recyclable Incinerated waste that cannot be reused is safely treated at the emission source, and contributes to the preservation of the global environment and the preservation of the local environment with the aim of eliminating social concerns about combustion, and raising the financial burden. It is expected that the effect of reduction and education will be great.
