Description

High Temperature Pyrolysis Incinerator {Gasfication Incinerator}

The present invention relates to a high-temperature pyrolysis incinerator, and more particularly, it is possible to prevent the generation of soot due to incomplete combustion by the complete combustion of the waste through the rotational combustion and secondary combustion and oxidation and reduction reaction of harmful components by the catalyst The present invention relates to a high temperature pyrolysis incinerator that can minimize air pollution and reduce equipment costs through miniaturization.

An incinerator is a device for burning off waste to be incinerated, and includes a waste inlet through which waste is input, a combustion chamber, and a residue hopper. In addition, a heat recovery apparatus may be further installed in the incinerator, and the combustion chamber may further include a secondary combustion chamber for complete combustion according to the type of the furnace.

Such incinerators are solid incinerators for incineration of solid wastes such as paper, wood and plastics, water incinerators for incineration of high moisture content, and organic wastes discharged from various workplaces such as waste liquids and waste solvents. It is classified as a waste liquid incinerator which incinerates waste liquid. In addition, depending on the type of waste, the whole amount of incinerator which is injected and incinerated without any processing of the waste, and brick-type refueled fuel (RDF) with uniform energy, moisture, and ash content of organic components of urban waste It is also classified as a waste fuel incinerator, which is processed and incinerated. Here, the total amount of incinerators can reduce the cost required for pretreatment, but the energy content of the waste varies greatly depending on the climate and components, and waste processing fuel incinerators are more energy efficient and can reduce the size of the incinerator and are harmful during the pretreatment process. Although there is an advantage in removing waste, there is a disadvantage in that a pretreatment cost is required.

And depending on the size, it may be classified into a small incinerator that can incinerate 400 ~ 800kg of waste every day, and a large incinerator for incineration of a large amount of waste generated in the city. Small incinerators have the advantages of easy installation, movement, and dismantling, and low installation and maintenance costs.However, they are simpler in structure and lower in combustion heat than other large incinerators, resulting in soot from incomplete combustion and large amounts of environmental hormones such as dioxins. There is a risk. Large incinerators are equipped with secondary combustion chambers and pollution prevention facilities to prevent the emission of smoke or environmental hormones due to incomplete elements, but complex installations and large facilities require wide installation space and equipment costs. There is a problem that can cause their backlash.

Accordingly, in a small waste treatment plant or a factory, it is not easy to incinerate waste by installing an incinerator, and there is a problem that waste treatment costs are inevitably increased by transferring the incinerator to a large incinerator.

Accordingly, the waste introduced into the waste input unit 11 is burned in the crucible 15, and the fuel is not supplied by maintaining the internal temperature of the crucible 15 at a high temperature by using the heat of combustion according to the combustion of the waste. The waste can be continuously burned without burning, and as the flame is burned while rotating in the crucible 15, the time and flow path of staying in the crucible 15 under high temperature are long, so that the waste is completely burned.

At this time, the secondary combustion chamber is preferably formed in the lid 20, a plurality of air input and discharge holes 21 along the upper outer peripheral surface of the lid 20 to supply air to the secondary combustion chamber and discharge the combustion heat ) May be formed.

In addition, it is preferable that a collecting device 27 for collecting fine dust and harmful gas is installed in the discharge hole 25 of the lid 20. At this time, it is preferable that the SiC catalyst is provided in the discharge hole 25 or the collecting device 27. A SiC catalyst is a catalyst made of a noble metal such as platinum or silver attached to a carrier formed of SiC. A noble metal catalyst promotes a chemical reaction such as oxidation or reduction of substances contained in a toxic gas without changing itself. It will play a role. Accordingly, the emission of harmful substances is minimized, and by collecting the environmental hormones such as fine dust and dioxin with the collecting device 27, it is possible to prevent environmental pollution.

In addition, a water storage unit (not shown) may be provided at one side of the lid 20 to store water supplied from the outside and discharge hot water heated by combustion heat. Accordingly, hot water can be used by heating water using the heat of the combustion gas generated in the main body 10 or the heat of combustion according to the secondary combustion occurring in the secondary combustion chamber inside the lid 20, thereby enabling the recycling of waste heat. do.

In addition, the lid opening and closing means 70 for mechanically opening and closing the lid 20 is preferably provided. Due to the weight and temperature of the lid 20, it is almost impossible to open and close the lid 20 manually, and to open and close the lid using the rotational force of the driving motor 77. Lid opening and closing means for this 70 is a hinge bracket 71 is installed on the top of the body 10, the lid bracket 73 connected to the lid 20 is integrally connected and rotatable to the hinge bracket (71) The opening and closing shaft 75 is installed, and the transmission portion 79, such as a chain for transmitting the rotational force of the drive motor 77 to the opening and closing shaft 75.

In addition, the fuel supply means 30 includes a fuel tank 31 in which fuel is stored, a plurality of fuel pipes 33 connecting the fuel tank 31 and the main body 10, and a fuel pipe 33 of the fuel in the fuel tank 31. It comprises a fuel pump 35 to supply to the body 10 through. In this case, the fuel pipe 33 for supplying fuel is installed to supply fuel through a plurality of nozzles installed at equal intervals on the main body 10, and the nozzles are installed at 1/2 points of the height of the main body 10, respectively. The fuel is injected into the upper side of the waste holder. And the fuel supply means 30 is preferably configured to supply fuel to the body 10 only when the initial operation and the internal temperature of the crucible 15 is lowered. That is, when the combustion of waste starts and the internal temperature of the crucible 15 becomes higher than a predetermined temperature, the fuel supply is stopped to prevent unnecessary fuel consumption.

In addition, the air supply means 40 is formed in the center of the crucible 15, the air rod 41 and the air rod 41 formed with a plurality of air supply holes 43 formed at regular intervals along the circumferential direction is blocked. It comprises an air blower 45 for supplying air containing oxygen to the interior of the body 10 through 41. At this time, the air rod 41 is preferably formed to protrude to 2/3 point of the height of the main body 10.

And it is more preferable that the air supply hole 43 is formed at the upper end and the middle and the lower end of the air rod 41, as shown in FIG. At this time, the upper air supply hole (43a) is formed to be inclined about 30 to 60 degrees in the left direction with respect to the radial direction in the horizontal direction, and is formed to be inclined downward about 15 degrees in the vertical direction. Accordingly, the rotational force is generated by the air supplied through the upper air supply hole 43a, and the flame is rotated to incinerate the waste, and the gas or soot generated by the incineration of the waste is pushed toward the flame and burned again. Unburned or incompletely burned material is completely burned.

In addition, the interruption air supply hole 43b is formed horizontally in the radial direction so that the air curtain is formed by the air supplied. Accordingly, the scattering dust generated by the incineration of the waste is blocked by the air curtain and does not rise up, but remains in the flame, thereby completely burning.

The lower air supply hole 43c is formed to be inclined at about 30 to 60 degrees in the same direction as the upper air supply hole 43a in the horizontal direction and is inclined downward at about 15 degrees in the vertical direction. Accordingly, the rotational force is also generated by the air supplied through the lower air supply hole 43c, thereby causing rotational combustion. In addition, a part of the gas and the soot generated during the incineration of the waste is moved downward by the air and continues to burn while exiting to the upper side of the waste holder 17 through the rotary combustion unit 50, the complete combustion is Will be done.

The horizontal inclination angle of the upper air supply hole 34a and the lower air supply hole 34c is set to 30 degrees to 60 degrees, even if the inclination angle is less than 30 degrees, the rotational force decreases, and the inclination angle exceeds 60 degrees. This is because the resistance can reduce the torque.

When the waste is incinerated using the high temperature pyrolysis incinerator of the present invention configured as described above is as follows.

The waste is introduced through the waste inlet 11 provided in the main body 10, and when the injected waste is mounted on the waste holder 17, the fuel supply means 30 is used to enter the crucible 15 of the main body 10. Supply a certain amount of fuel. Subsequently, the air is supplied into the crucible 15 through the air blower 45 of the air supply means 40, and at the same time, the fire is drawn into the crucible 15 through the residue treatment unit 17.

As a result, the fuel is burned and the waste is burned, and the temperature inside the crucible 15 is rapidly increased. Thereafter, when the temperature inside the crucible 15 reaches a predetermined temperature or more, the fuel supply is stopped, and only air is supplied into the crucible 15 through the air supply means 40. Of course, when the internal temperature of the crucible 15 is below a certain level, fuel must be additionally supplied to increase the internal temperature of the crucible 15.

The air supply means 40 supplies the air containing oxygen through the air supply hole 43 formed in the air rod 41 into the crucible 15 and generates rotational force to allow rotational combustion. Specifically, the lower air supply hole 43c is inclined in one direction with respect to the radial direction in the horizontal direction so that the rotational force is generated by the air supplied. Accordingly, the flame generated by the incineration of the waste is rotated in the crucible, whereby the gas and the soot components generated by the incineration of the waste are continuously burned for a long time in the crucible to achieve complete combustion. In addition, since the lower air supply hole 43c is formed to be inclined downward, a portion of the gas and the smoke generated by the incineration of the waste moves downward, and then the waste is burned through the rotary combustion unit 50. Combustion is continuously performed while exiting to the upper side of the cradle 17, so that complete combustion is achieved. In other words, the flow path between the gas and the soot is long, and thus the combustion time is increased, thereby completely burning.

In addition, the air supplied horizontally in the radial direction from the interrupted air supply hole 43b forms an air curtain so that no scattering dust or the like generated due to incineration of the waste rises. As a result, scattering dust or the like remains in the flame and is burned to complete combustion.

On the other hand, the air supplied from the upper air supply hole (43a) is to be rotated combustion with the air supplied from the lower air supply hole (43c), and by the air supplied through the suspended air supply hole (43b) By pushing the gas or soot raised above the formed air curtain to the lower part of the air curtain, the gas or soot generated by incineration of the waste is burned again by the flame to achieve complete combustion.

At this time, if the waste is a kind that does not discharge soot or environmental hormones, such as paper or wood, the waste can be incinerated without closing the lid 20, but if the waste is a kind of environmental hormones such as plastic or styrofoam In the lid opening means 70, the incineration should proceed in a closed state.

When incineration is performed while the lid 20 is closed, secondary combustion is performed in the secondary combustion chamber formed inside the lid 20, and through the air input and discharge holes 21 formed in the lid 20. Air is introduced into or discharged from the secondary combustion chamber. In addition, when the lid 200 is provided with a water storage unit, the water of the water storage unit may be heated by the heat of the combustion gas from the crucible 15 or the heat of combustion according to the secondary combustion, thereby enabling the use of hot water. Recycling can improve energy efficiency.

In addition, by collecting the environmental hormones such as fine dust or harmful gases and dioxins using the collecting device 27 installed on the lid 20, it is possible to reduce the fine dust discharged to the outside. At this time, by using the SiC catalyst provided in the discharge hole 25 or the collecting device 27 of the lid 20 to minimize the emission of harmful substances by the oxidation or reduction of the substances contained in the noxious gas.
