The incineration boiler 100 of the present invention includes a means for injecting a material to be burned, a means for burning the target material in stages, and a means for injecting air into the incineration boiler 100.

As shown in Fig. 1, the incineration boiler 100 is configured to burn the target material step by step while the cylindrical body lying horizontally goes from left to right. External air is injected into the body to ensure efficient combustion.

The front of the incineration boiler 100 is composed of a horizontal combustion cylinder 102 lying horizontally. The horizontal combustion cylinder 102 is configured so that a combustion target material can be injected from one side, and an intermediate connector 112 through which flame and smoke move is connected to the other side. The intermediate connection pipe 112 is connected to the vertical communication cylinder 114 in which the communication 116 is installed. As a whole, the target material entering the horizontal combustion cylinder 102 is burned by flame and high-temperature air, and the combustion by-products escape to the communication 116 through the intermediate connection pipe 112 and the vertical combustion cylinder 114. do.

A hopper 104 is installed at an upper end of one side of the horizontal combustion cylinder 102, and a rotating wheel 106 is installed inside the hopper 104. The hopper 104 is provided in a concave shape while going downward, and a flame-retardant material such as vinyl or plastic is injected. The rotating wheel 106 slowly moves the flame retardant material introduced through the hopper 104 downward while rotating downward in the shape of a waterwheel.

A door 108 is installed on one side of the horizontal combustion cylinder 102, and when the door 108 is opened, a passage through which material can be injected is opened. During the operation of the incineration boiler 100, the door 108 is closed to isolate the interior and exterior of the horizontal combustion cylinder 102.

Combustible materials such as wood, paper, and oil are introduced through the passage through which the door 108 opens and closes.

A first air inlet pipe 110 is installed at one lower end of the horizontal combustion cylinder 102. The first air inlet pipe 110 is a cylindrical tube with an open interior, and induces external air to enter the interior of the horizontal combustion cylinder 102. A plurality of air holes 110a are formed in the first air inlet pipe 110 installed inside the horizontal combustion cylinder 102 so that air introduced from the outside flows smoothly into the interior of the horizontal combustion cylinder 102. Although not shown in the drawings, a blowing means may be installed in the first air inlet pipe 110 to force external air into the horizontal communication cylinder 102.

A blowing fan 118 is installed outside the horizontal combustion cylinder 102. The second air inlet pipe 120 is connected to the blowing fan 118, the second air inlet pipe 120 is connected to the side of the horizontal combustion cylinder 102, and is connected to the heating pipe 136 installed therein. . External air is introduced into the second air inlet pipe 120 by the blowing fan 118, and the spiral combustion pipe 132 in a state where the temperature rises while passing through the heating pipe 136 inside the incineration boiler 100 Is committed to. And some are supplied to the intermediate connection pipe 112 and the vertical combustion cylinder 114 through a separate pipe.

A third air injection pipe 122 is connected to the side of the horizontal combustion cylinder 102, and one end of the third air injection pipe 122 is connected to the heating pipe 136 inside. And the other end branched into several gales and connected to the intermediate connector 112 and the vertical communication tube 114.

Accordingly, the air introduced through the external blowing fan 118 passes through the second air inlet pipe 120 and is connected to the heating pipe 136 inside the horizontal combustion cylinder 102. The air whose temperature has risen while passing through the heating pipe 136 comes out through the third air inlet pipe 122 and then enters the intermediate connection pipe 112 and the vertical combustion cylinder 114 again. Air that has entered the incineration boiler 100 through the second air inlet pipe 120 and the third air inlet pipe 122 is used for combustion of the target material.

The sieve 124 installed under the rotating wheel 106 is composed of a grid-formed wire mesh. The sieve 124 is formed with a hole 124a through which the flame retardant material can pass. The flame-retardant material injected through the rotating wheel 106 is accumulated on the sieve 124, and passes through the hole 124a while being melted by heat generated in the lower combustion space. The liquid flame retardant material burns in the lower space. The size of the holes 124a formed in the strainer 124 varies depending on the size of the injected flame-retardant material, but in the case of a square grid, it is common to have a width of about 1 cm to 5 cm, respectively.

The lower side of the sieve 124 is a place where combustion occurs for the first time in the incineration boiler 100 of the present invention, and is defined as a first combustion space for convenience. In the first combustion space located at the inlet side of the horizontal combustion cylinder 102, the flame-retardant material input through the hopper 104 above and the combustible material input through the door 108 are mixed and burned for the first time. A separate ignition device (not shown) may be installed for the first ignition after input of the material.

In addition, an ash tray (not shown) capable of receiving and discharging ash may be additionally installed below the first combustion space.

Air required for combustion in the first combustion space is supplied through the first air inlet pipe 110.

A first funnel 126 is installed in the first combustion space () on the opposite side of the place where the door 108 is installed. The first funnel 126 is configured to narrow as it goes to the outside of the first combustion space. A first opening 128 is formed at the end of the first funnel 126. The first opening 128 serves as a passage through which by-products generated while being burned in the first combustion space and a target material that has not been completely burned move.

The portion connected to the first opening 128 becomes a second combustion space. Inside the second combustion space, a tube for combustion as shown in FIGS. 6 and 7 is installed.

In the center, the wire mesh 130 is installed in a horizontally lying state. The wire mesh 130 is a mesh made of a metal material and forms a space for combustion.

Outside of the wire mesh 130, a spiral combustion pipe 132 is installed in a surrounding shape. The spiral combustion tube 132 has a plurality of holes 132a formed therein so that air is discharged, and combustion occurs around the hole of the spiral combustion tube 132.

The outer side of the spiral combustion pipe 132 is installed so as to surround the heat insulating cylinder 134. The heat insulating cylinder 134 prevents heat generated while combustion occurs in the spiral combustion pipe 132 from escaping to the outside. In addition, a heat storage ceramic 144 for accumulating heat may be embedded in the wall of the heat insulating cylinder 134. The heat storage ceramic 144 is made of solid particles of a ceramic material, and accumulates high temperature heat to be used in the combustion process.

Outside of the heat insulating cylinder 134, a heating tube 136 is installed so as to wrap it in a spiral. The heating tube 136 is a part that heats the air supplied from the outside so that the temperature rises as it passes. The inlet of the heating tube 136 is connected to the second air inlet tube 120, and the outlet is connected to the inlet of the third air inlet tube 122 and the spiral combustion tube 132. Therefore, part of the air entering the heating pipe 136 is injected into the spiral combustion pipe 132 in a heated state and used for combustion, and the remainder passes through the third air inlet pipe 122 to communicate vertically with the intermediate connection pipe 112 It is put into (114).

In order to increase the heating efficiency of air, the outlet of the heating tube 136 is disposed close to the first funnel 126 and the inlet is disposed far from the first funnel 126.

As shown in Fig. 8, heated air is released from the hole 132a formed in the spiral combustion tube 132. In addition, since there is an unburned target material around the spiral combustion pipe 132, secondary combustion of the target material occurs as the high-temperature air and the flame moved from the front meet.

The internal structure of the intermediate connector 112 is shown in FIG. 9.

One or more straight combustion pipes 138 extending in a straight line from the inlet side are installed inside the intermediate connection pipe 112. The linear combustion pipe 138 also has a plurality of holes 138a, so that air is discharged. Due to this, the third combustion occurs in the periphery of the linear combustion pipe 138 and in the inner space of the intermediate connection pipe 112.

The third air inlet pipe 122 is connected to the intermediate connection pipe 112 to supply heated external air while passing through the heating pipe 136.

A second opening 142 is formed on the opposite side of the intermediate connector 112 to communicate with the vertical communication cylinder 114. A second funnel 140 is installed from the middle of the intermediate connector 112 toward the second opening 142. Similar to the first funnel 126 described above, the second funnel 140 also has a structure whose diameter is narrowed in the traveling direction. Therefore, the flame and the combustion material can be smoothly moved to the vertical combustion cylinder (114).

In the vertical combustion cylinder 114, the fourth combustion occurs as the flame introduced from the intermediate connector 112 connected to the lower side, the combustion target material, and air are mixed. The hot air and the flame rise upward, and combustion is actively generated by the heated air supplied from the third air inlet pipe 122 connected from the outside.

In the same manner as before, the heat storage ceramic 144 is embedded in the wall of the vertical combustion cylinder 114 to perform heat insulation and heat storage.

A communication 116 is connected above the vertical communication cylinder 114. A communication connection part 146 is installed below the communication 116 in the vertical communication cylinder 114. The communication connection part 146 has a structure in which the bottom surface is blocked and a part of the side surface is open. Due to this, combustion by-products such as flame and smoke coming up from the bottom are bypassed to the side and introduced into the interior of the communication connection part 146. And combustion occurs once again inside the communication connection part 146, which becomes the fifth combustion.

The lower and upper surfaces of the communication connection part 146 are open, and a lower wire mesh 148 is installed therein. The lower wire mesh 148 has a mesh structure so that air or combustion materials flow downward into the inside of the communication connection part 146.

An inner cylinder 150 is installed inside the communication connection part 146. The inner cylinder 150 is open up and down, and the side surface is composed of a cylinder made of an iron plate without an opening. The lower surface of the inner cylinder 150 is fixed to the upper surface of the lower wire mesh 148. A heat storage ceramic 144 is stored inside the inner cylinder 150.

An intermediate net 152 is installed on the upper surface of the communication connection part 146. The intermediate net 152 has a structure in which a circular opening is formed inside the disk. The diameter of the inner opening is the same as the outer diameter of the inner cylinder 150. For this reason, the inner cylinder 150 is fixed to the inside of the intermediate net 152. A plurality of air exhaust holes 152a are formed in the intermediate network 152.

A space is formed due to the inside of the communication connection part 146, the upper surface of the lower wire mesh 148, and the outside of the inner cylinder 150, and air or combustion substances entering through the lower wire mesh 148 from the bottom are air discharge holes in the upper part. As it is discharged through (152a), it is burned in the vicinity of the upper surface of the intermediate net 152.

In addition, air and combustion materials that have entered upward through the center of the lower wire mesh 148 rise while in contact with the heat storage ceramic 144, and transfer heat to the heat storage ceramic 144 or receive heat from the heat storage ceramic 144. Is heated.

The lower surface of the upper connection part 154 is connected to the upper surface of the communication connection part 146. Since the upper connection part 154 has the same diameter as the communication connection part 146, it forms one cylindrical moving passage from the communication connection part 146 to the upper connection part 154. The upper surface of the upper connection part 154 is connected to the communication 116.

A plurality of air inlet holes 154a are formed on the side of the upper connection part 154. Air in the vertical combustion cylinder 114 is introduced into the upper connection part 154 through the air inlet hole 154a.

In the interior of the upper connection part 154, the space of the upper part is passed through the lower wire mesh 148, and the target material passed through the inner cylinder 150, and communicated through the third air inlet pipe 122. A space where the air entering the connection part 146 and passing through the air outlet hole 152a of the intermediate network 152, the target material and air entering the interior of the upper connection network 154 through the air inlet hole 154a are combined Becomes. Here, the target material is burned 5 times and all harmful substances are removed.

Smoke or by-products generated after the 5th combustion is completed are discharged to the outside through the upper communication channel 116. However, as combustion occurs several times by a high-temperature flame, not only combustible substances but also flame-retardant substances are decomposed by combustion, and harmful substances such as dioxin are all removed while burning together. Therefore, only substances such as pure water or carbon dioxide are left behind what is discharged through the communication 116.

Although preferred embodiments of the present invention have been described above with reference to the accompanying drawings, the technical configuration of the present invention described above is another specific form without changing the technical spirit or essential features of the present invention by those skilled in the art. It will be appreciated that it can be implemented with.
