Description

Melting Furnace Using Anionic Oxygen

The present invention relates to a melting furnace capable of thermally treating various wastes.

Recently, due to the advancement of the industry and the improvement of living standards, various types of wastes are rapidly increasing, and attention is being focused on waste treatment methods. Waste treatment methods include reducing the amount of waste generated, recycling the generated waste, and incineration or landfill of non-recyclable waste. In the case of domestic waste, most of the waste depends on landfilling. Direct incineration is mainly used as a method of incineration of waste.

However, in the case of the direct incineration method, there is a drawback of generating toxic harmful substances such as dioxine, furan, etc., which are emerging as serious environmental problems after waste combustion. Therefore, the burden due to the addition of a facility for treating harmful substances may be increased. In addition, since the energy obtained by burning fossil fuel such as diesel oil is separately used as an external heat source for waste combustion, it may be a waste of resources.

SUMMARY OF THE INVENTION An object of the present invention is to provide a melting furnace using anion oxygen that can thermally decompose all wastes into pollution-free, and recycle the decomposed ash remaining after decomposition.

Furnace using anion oxygen according to the present invention for achieving the above object, the furnace body having an internal space, the waste inlet and the decomposition gas discharge port is formed on the upper surface, at least one ash outlet on the side; An inlet door for opening and closing the waste inlet; An outlet door for opening and closing the ash outlet; A dust collector installed at the decomposition gas outlet and collecting and collecting ash contained in the decomposition gas in the furnace body; A perforated plate disposed to be spaced apart from a bottom surface of the furnace body and having a plurality of through holes penetrated vertically; And an anion oxygen supply unit for supplying magnetized anion oxygen toward an upper region of the perforated plate located in the furnace body.

According to the present invention, since the waste is spontaneously decomposed by high-temperature radiant heat using anion oxygen, environmentally friendly waste treatment can be made as compared with the conventional direct incineration method. And, after igniting charcoal or the like, since waste can be thermally decomposed without additionally supplying additional heat source into the furnace body, energy can be saved. In addition, the inorganic mineralized ceramics may be used for industrial purposes, and the ash recovered through the dust collector may be used for sterilization, insecticide, fertilizer, etc., and thus may have an effect of resource recycling.

1 to 3, the melting furnace 100 using anion oxygen is the furnace body 110, the inlet door 120, the outlet door 130, the dust collector 140, the perforated plate 150, and Anion oxygen supply unit 160 is included.

The furnace body 110 has an interior space. For example, the furnace body 110 may be formed in a cuboid chamber shape having an internal space. In the internal space of the furnace body 110, a thermal decomposition process of waste is performed. The waste inlet 111 and the decomposition gas outlet 112 are formed on the upper surface of the furnace body 110. At least one ash outlet 113 is formed at the side of the furnace body 110. For example, the ash outlets 113 may be formed on each side of the furnace body 110 one by one. In the center of the side of the furnace body 110, the footrest 114 may be installed so that the operator can rise.

The furnace body 110 may have a double partition structure having an inner wall 115a and an outer wall 115b. A partition space defined by the inner wall 115a and the outer wall 115b may be filled with a thermal medium, such as water. The water in the partition space may be heated by the heat generated during the thermal decomposition process of the waste in the furnace body 110 and used for hot water or heating or electric power generation. In this case, pipes for supplying and discharging water in the partition space may be provided. As another example, the partition space may be filled with an insulating material.

The inlet door 120 opens and closes the waste inlet 111. When the inlet door 120 is opened, waste may be introduced into the furnace body 110 through the opened waste inlet 111. Inlet door 120 may be hinged to the upper surface of the furnace body 110 to be rotated up and down. The inlet door 120 may be locked by the locking mechanism 121 in a state in which the waste inlet 111 is closed.

The locking mechanism 121 may include a locking lever 122 rotatably coupled to the furnace body 110 and a pushing block 123 linked to the locking lever 122. The pushing block 123 operates to fix or release the inlet door 120 according to the rotation of the locking lever 122. A shock absorber 124 is installed between the inlet door 120 and the furnace body 110 to cushion the opening and closing operation of the inlet door 120.

The outlet door 130 opens and closes the outlet 113 again. When the outlet door 130 is opened, the thermally decomposed ash may be discharged from the waste through the opened ash outlet 113. The outlet door 130 may be hinged to the side of the furnace body 110 to be rotated up and down. The outlet door 130 may be locked by the handle type locking mechanism 131 in a state where the outlet 113 is closed. The outlet door 130 may be provided with a thermometer for measuring the temperature in the furnace body (110).

The dust collector 140 is installed at the decomposition gas outlet 112. The dust collector 140 collects and collects ash contained in the cracked gas in the furnace body 110. That is, the dust collector 140 purifies and discharges the decomposition gas generated during thermal decomposition of the waste, and recovers ash contained in the decomposition gas. A portion of the decomposition gas inlet 112 from the decomposition gas inlet may be provided with a mesh network for filtration.

The perforated plate 150 is disposed spaced apart from the bottom in the furnace body 110. The lower space 116 of the perforated plate 150 may function as a space where the charcoal can be placed. Here, the charcoal may be used for ignition, and may be used to remove moisture in the furnace body 110 during initial use of the melting furnace 110 or to remove moisture of waste introduced into the furnace body 110. In addition to charcoal, it is also possible to use rice straw. The lower space 116 of the perforated plate 150 may be in communication with the outside through the vent pipe 117 installed from the outside of the furnace body 110. The vent pipe 117 may be used to supply air to the lower space 116 of the perforated plate 150 or to clean the lower space 116 of the perforated plate 150 after the thermal decomposition of the waste is completed.

The ceramic layer may be disposed on the upper surface of the perforated plate 150. The ceramic layer receives the heat generated during the burning of charcoal to generate far-infrared radiation and supply it as waste. In addition, the ceramic layer may receive heat generated during thermal decomposition of the waste to generate far-infrared radiant energy and resupply the waste. Accordingly, thermal decomposition of the waste can be promoted. The ceramic layer may be composed of a ceramic in powder form, or may be configured by recycling the ceramic ash thermally decomposed by the melting furnace 100. The ceramic layer may be omitted.

The perforated plate 150 has a structure in which a plurality of through holes penetrated vertically through the plate member. The through holes communicate the lower space 116 of the perforated plate 150 and the upper space of the furnace body 110 located above the perforated plate 150.

For example, the through holes may include first through holes 151 and second through holes 152. The first through holes 151 are larger than the second through holes 152, and may be arranged at regular intervals in the center of the perforated plate 150. The second through holes 152 may be arranged at regular intervals between the edge of the perforated plate 150 and the first through holes 151.

The first through holes 151 allow the complexed charcoal to be placed in the lower space 116 of the perforated plate 150, respectively. In addition, the spark generated during the burning of the char may contact the ceramic plates through the first through holes 151 to heat the ceramic plates. The second through holes 152 may be provided with air permeability between the char and the waste, so that the moisture is removed of the waste by the char, and can supply oxygen for burning charcoal.

The anion oxygen supply unit 160 supplies magnetized anion oxygen to an upper region of the perforated plate 150 located in the furnace body 110, for example, an upper region of the ceramic layer. At this time, the magnetized anion oxygen has magnetization energy. Anion oxygen having magnetization energy causes the inside of the furnace body 110 to be in a reducing state to generate radiant energy. This radiant energy accelerates the molecular movement of the waste, causing it to self-heat. Accordingly, the waste can be dried by self heating. The dried waste may be pyrolyzed to carbonize and finally mineralized.

An example of the operation of the melting furnace 100 having the above-described configuration is as follows.

First, the ignition and dehumidification material such as char, ignited and introduced into the furnace body (110). Thereafter, a ceramic layer may be formed on the upper surface of the perforated plate 150 as necessary. Thereafter, the waste is injected into the furnace body 110 through the waste inlet 111, and then the waste inlet 111 is closed by the inlet door 120.

Then, the heat generated during the combustion of the char is transferred to the ceramic layer and far infrared radiation is generated and transferred to the waste. At the same time, the anion oxygen supply unit 160 supplies magnetized anion oxygen to the waste in the furnace body 110. Then, the anion oxygen having magnetization energy causes the inside of the furnace body 110 to be in a reducing state to generate radiant energy. This radiant energy, together with the radiant energy generated by the ceramic layer, promotes the molecular movement of the waste and self-heats. Accordingly, the lower portion of the waste placed in the anion oxygen supply region is dried by self-heating and thermally decomposed to form a carbonized layer.

High temperature radiant heat of 400 ° C. or higher is generated in the carbonized layer. Due to such high temperature radiant heat, the carbonized layer is decomposed naturally and mineralized into a ceramic mineral in the form of ash. At this time, the inorganicized part of the waste is reduced in volume to form a ceramic layer made of ceramic inorganic material, and the upper part of the inorganicized part is moved to the anion oxygen supply region in a dry state by radiant heat, and then carbonized in the above-described process. , Weaponized. If this process is repeated, the entire waste can be mineralized. Ceramic mineralized in the form of ash may be discharged through the ash outlet 113 opened by the outlet door 130.

As such, since the waste is spontaneously decomposed by high-temperature radiant heat using anion oxygen, a very small amount of harmful toxic substances may be generated as compared with the generation of harmful toxic substances such as dioxins due to incomplete combustion in the conventional direct incineration method. . Decomposed gas containing such a very small amount of harmful toxic substances can be purified and discharged into the atmosphere to meet the environmental standards through the dust collector 140, it can be environmentally friendly waste treatment.

Then, after igniting the charcoal, since the waste can be thermally decomposed without additionally supplying a further heat source into the furnace body 110, it may have an energy saving effect. In addition, since the inorganic mineralized ceramic minerals can be used for industrial purposes, there may be an effect of resource recycling.

On the other hand, the decomposition gas generated in the thermal decomposition process of the waste in the furnace body 110 passes through the dust collector 140. The dust collector 140 purifies and discharges the cracked gas and recovers the ash contained in the cracked gas. Here, the recovered ash may be used for the purpose of sterilization, insecticide, fertilizer, etc. as a mineral having efficacy of sterilization, fertilizer and the like.

The anion oxygen supply unit 160 may be configured in various ways. For example, the anion oxygen supply unit 160 may include first supply pipes 161, second supply pipes 162, magnetizers 163, and valves 164. Both ends of the first supply pipe 161 are formed to be open. Each of the first supply pipes 161 penetrates the furnace body 110 along the circumference of the furnace body 110. Each of the first supply pipes 161 penetrating the furnace body 110 may be disposed adjacent to the edge of the furnace body 110 to supply magnetized anion oxygen to the edge of the waste in the furnace body 110. The first supply pipes 161 may be arranged in two rows up and down along the circumference of the furnace body 110.

The second supply pipe 162 is formed in the form that both ends are opened. One end of each of the second supply pipes 162 is installed through the furnace body 110. Each of the second supply pipes 162 is disposed closer to the center of the furnace body 110 than each one end of the first supply pipes 161 passes through the furnace body 110 so that the second supply pipes 162 are disposed at the center of the waste in the furnace body 110. The magnetized anion oxygen can be smoothly supplied to the side. Although the second supply pipe 162 is illustrated as being provided in two, it is also possible to provide one or three or more.

The magnetizers 163 are respectively installed in the first supply pipes 161. The magnetizers 163 may be installed to surround each circumference of the first supply pipes 161. The magnetizers 163 generate magnetized anion oxygen by magnetizing external air passing through each inside of the first supply pipes 161. The magnetizer 163 may include permanent magnets. The permanent magnets are configured to have an arrangement and magnetic force capable of magnetizing external air passing through the inside of the first supply pipe 161 to generate anion oxygen, and may be disposed around the first supply pipe 161. Similarly, the magnetizers 163 may be installed in the second supply pipes 162, respectively, to magnetize the external air passing through the respective interiors of the second supply pipes 162 to generate magnetized anion oxygen.

The valves 164 are installed in the first and

second supply pipes

161 and 162, respectively. The valves 164 regulate the flow rate of magnetized anion oxygen supplied to the furnace body 110 through the first and

second supply pipes

161 and 162. The magnetized anion oxygen naturally flows into the furnace body 110 through the first and

second supply pipes

161 and 162 during the combustion of charcoal and thermal decomposition of the waste in the furnace body 110. Depending on whether each of the opening and closing, magnetized anion oxygen may be supplied to or blocked by the furnace body 110 through the first and second supply pipes (161, 162). In addition, by adjusting the opening degree of the valves 164, the flow rate of the magnetized anion oxygen is supplied to the furnace body 110 through the first and

second supply pipes

161 and 162 may be adjusted.

The dust collector 140 may include a first dust collector 141 and a second dust collector 146.

Referring to FIG. 4, the first dust collecting unit 141 receives circulating water by a pump or the like and discharges it through the first discharge hole 142a. The first dust collector 141 injects the circulating water to the cracked gas supplied through the cracked gas outlet 112. For example, the first dust collecting unit 141 may include a nozzle tube 143 having a plurality of nozzles. The nozzle tube 143 may receive the circulating water sent from the pump and inject the circulating water into the decomposition gas in the first dust collecting unit 141 through the nozzles.

As the first dust collecting part 141 injects the circulating water to the decomposition gas, the ash separated and buoyant on the internal circulating water is recovered to the recovery tank through the first recovery hole 142b located above the first discharge hole 142a. In addition, the remaining cracked gas is exhausted.

That is, the ash in the cracked gas falls to the lower portion of the first dust collecting part 141 together with the circulating water, and is separated and supported on the internal circulation water of the first dust collecting part 141. The internal circulating water of the first dust collecting part 141 is discharged through the first discharge hole 142a and then sent back to the first dust collecting part 141 by a pump. The buoyant ash is recovered to a recovery tank (not shown) through the first recovery hole 142b when the ash is raised to the height of the first recovery hole 142b located above the first discharge hole 142a. The remaining cracked gas in the first dust collector 141 is discharged to the second collector 146.

The second dust collecting part 146 receives the circulating water and discharges it through the second discharge hole 147a. The second dust collector 146 injects the circulating water to the remaining cracked gas supplied from the first dust collector 141. A nozzle tube 148 similar to the structure described above may be used to inject circulating water into the remaining cracked gas.

The second dust collecting part 146 separates and floats the floated ash above the internal circulating water as the circulating water is injected into the residual decomposition gas through the second collecting hole 147b located above the second discharge hole 147a. And the remaining cracked gas is exhausted.

That is, the remaining cracked gas falls with the circulating water to the lower portion of the second dust collecting part 146 and is separated and supported on the internal circulating water of the second dust collecting part 146. The internal circulating water of the second dust collecting part 146 is discharged through the second discharge hole 147a and then sent back to the second dust collecting part 146 by a pump. When the buoyant ash is raised to the height of the second recovery hole 147b located above the second discharge hole 147a, the ash is recovered to the first dust collecting part 141 through the second recovery hole 147b, and then the first ash is collected. The ash separated from the dust collector 141 is recovered to a recovery tank. The remaining cracked gas in the second dust collecting part 146 is exhausted.

As such, since the cracked gas generated in the furnace body 110 passes through the first and

second dust collectors

141 and 146, the ash contained in the cracked gas in the furnace body 110 may be recovered as much as possible. In addition, the ash-filtered gas can be purified to a level that can meet environmental standards and discharged to the atmosphere.

In order to further purify the residual cracked gas exhausted from the second dust collector 146, as shown in FIG. 1, one or more additional dust collectors 149 may be provided. The additional dust collector 149 may separate and collect ash from the cracked gas in the same manner as the first and

second dust collectors

141 and 146, and may further include filtration means such as a filter medium.

Could be. Accordingly, the true scope of protection of the invention should be defined only by the appended claims.
