Description

Complete combustion compact self-pyrolysis device

[0001] The present invention relates to a magnetic pyrolysis device, and more particularly, to a compact magnetic pyrolysis device that, when organic waste, which is a raw material to be pyrolyzed, is input into the magnetic pyrolysis device, heats and decomposes the input organic waste through a magnetic pyrolysis reaction to increase the decomposition treatment efficiency of the organic waste, and further, performs secondary combustion of exhaust gas generated during the magnetic pyrolysis process of organic waste in a heater installed in conjunction with a pyrolysis treatment room of the magnetic pyrolysis device to remove smoke contained in the exhaust gas and purify the exhaust gas, and then uses an electric precipitator and activated carbon in a subsequent odor deodorization unit to remove even odor from the exhaust gas, thereby maximizing the purification level of the exhaust gas generated during the magnetic pyrolysis process of organic waste.

[0002] In general, a self-pyrolysis device that decomposes various recyclable materials such as organic waste without combustion is, for example, an organic matter decomposition treatment device described in Patent Document 1 (Japanese Patent Application Laid-Open No. 2010-75823).

[0003] This magnetic pyrolysis device places organic waste into a bowl-shaped decomposition pot, ignites it with an ignition rod, and introduces magnetized air through the air inlet of a magnetized air introduction tube to magnetically combust the organic matter at low temperatures without extinguishing the flame, thereby performing combustion decomposition. Furthermore, smoke containing tar and water vapor generated by the combustion decomposition process is allowed to rise, and the tar and water vapor are separated and exhausted in a tar removal section.

[0004] In addition, in the organic waste decomposition treatment device of Patent Document 2 (Japanese Patent Application Laid-Open No. 2011-5457), organic waste fed into the decomposition treatment facility is self-combusted at a low temperature, and smoke containing tar and moisture generated during combustion decomposition treatment is raised, so that tar is almost completely removed in the tar removal section, and deodorized through water injection in the deodorization section and discharged into the atmosphere.

[0005] However, in the conventional techniques described in the aforementioned patent documents 1 and 2, there were limitations in removing harmful components such as tar and odor from exhaust gas generated after self-pyrolysis of organic waste, and as a result, there were problems such as exhaust gas being emitted in which harmful components were not completely removed.

[0006] Accordingly, the purpose of the present invention is to provide a compact self-pyrolysis device that, when organic waste, which is a raw material to be pyrolyzed, is inputted into a self-pyrolysis device, heats and decomposes the input organic waste through a self-pyrolysis reaction to increase the decomposition treatment efficiency of the organic waste, and further, the exhaust gas generated during the self-pyrolysis process of the organic waste is subjected to secondary combustion in a heater installed in conjunction with the pyrolysis treatment room of the self-pyrolysis device to remove smoke contained in the exhaust gas and purify the exhaust gas, and then, in a subsequent odor deodorization unit, removes even odor from the exhaust gas using an electric precipitator and activated carbon, thereby maximizing the purification level of the exhaust gas generated during the self-pyrolysis process of the organic waste.

[0007] The objectives of the present invention are not limited to those mentioned above. Other objectives and advantages of the present invention not mentioned above can be understood through the following description and will be more clearly understood through the embodiments of the present invention. Furthermore, it will be readily apparent that the objectives and advantages of the present invention can be realized by the means and combinations thereof set forth in the claims.

It may include a second blower for blowing and cooling the exhaust gas to a temperature below a predetermined temperature, an odor removal unit for removing odor from the exhaust gas cooled to a temperature below the predetermined temperature, and a second chimney formed on the opposite side of the first chimney on the housing and discharging the final exhaust gas from which the odor has been removed by the odor removal unit into the atmosphere.

[0010] In addition, the heater includes a heater housing forming the heater, a heating wire formed and arranged in a spiral shape inside the heater housing, a first opening connected to the first flue, a second opening formed on the opposite side of the first opening and connected to the second flue, a speed sensor measuring a movement speed of exhaust gas flowing into the heater housing, and an electronic control valve opening or closing the second opening, wherein the electronic control valve receives a movement speed of exhaust gas passing through the heater housing through the speed sensor, and when the movement speed of the exhaust gas exceeds a maximum value of a preset reference speed range, gradually closes the second opening to control the movement speed of the exhaust gas to become a value within the reference speed range.

[0011] In addition, the heater housing may be formed so that the interior thereof is curved along the curve of the heating wire so that the first movement speed of the exhaust gas moving inside the heater housing is lower than the second movement speed of the exhaust gas discharged from the thermal decomposition treatment chamber and moving inside the first flue gas.

[0012] In addition, the odor deodorizing unit can deodorize the odor contained in the exhaust gas by mixing the negative potential generated from the negative potential generator with the exhaust gas.

[0013] In addition, the odor removal unit can remove odors contained in the exhaust gas by allowing the exhaust gas to pass through activated carbon.

[0032] Figure 6 illustrates a concept of controlling the movement speed of exhaust gas within a heater according to another embodiment of the present invention.

[0033] Figure 7 illustrates the internal structure of a heater housing according to another embodiment of the present invention.

[0034] Hereinafter, the operation of each component of a complete combustion type compact self-pyrolysis device (100) according to one embodiment of the present invention will be described in more detail with reference to FIGS. 1 to 7.

[0035] The housing constitutes the exterior of the magnetic pyrolysis device (100). This housing may be formed of a metal such as iron, as in the magnetic pyrolysis device shown in FIG. 4.

[0036] A raw material inlet (110) is formed at the top of the housing, and raw materials to be thermally decomposed are introduced.

[0037] The pyrolysis treatment room (114) pyrolyzes raw materials such as organic waste fed into the raw material input port (110) without combustion through a self-pyrolysis reaction.

[0038] The lower slide plate (112) is formed between the raw material input port and the thermal decomposition treatment chamber and is configured to open or close in a sliding manner so that the raw material input from the raw material input port is discharged into the thermal decomposition treatment chamber.

[0039] For example, the user opens the raw material inlet (110), puts in raw materials to be pyrolysis treated, such as organic waste, and then closes the raw material inlet. When the raw material inlet is closed, the lower slide plate (112) opens and the raw materials are discharged into the pyrolysis treatment chamber. At this time, as shown above, the raw material inlet and the lower slide plate are designed in duplicate at the top of the pyrolysis treatment chamber so that air does not flow into the pyrolysis treatment chamber, and also exhaust gas generated in the pyrolysis treatment chamber does not leak out through the raw material inlet.

[0040] In addition, an inspection lever may be installed inside the pyrolysis treatment room (114), and this inspection lever can check the position of the raw material to determine the amount and timing of input of the raw material.

[0041] The first blower (115) is installed on the other side of the upper side of the thermal decomposition treatment chamber on the housing, and as shown in Fig. 2, it generates an air flow in the direction of the first chimney so that the exhaust gas is discharged to the first chimney (116). This first blower may be formed as a small blower, etc., as shown in Fig. 4, but is not limited thereto.

[0042] That is, the thermal decomposition treatment room (114) with the outside air blocked becomes under a negative pressure (lower pressure than the atmospheric pressure), and in this negative pressure state, air can be introduced from the outside into the thermal decomposition treatment room through the first blower (115). The air introduced in this way passes through the magnetic field within the magnetic generator and is introduced into the thermal decomposition treatment room, thereby making it possible for the indoor temperature of the thermal decomposition treatment room to become a plasma state of around 300 degrees.

[0043] At this time, in the atmosphere of the thermal decomposition treatment room in the plasma state as above, oxygen in the thin air reacts and becomes radicals to become strong and active negative ions, and these negative ions react with carbon molecules of organic waste etc. introduced into the thermal decomposition treatment room (114), causing a violent thermal decomposition reaction at the contact surface of the organic waste.

[0044] Accordingly, the raw material fed into the pyrolysis treatment room is oxidized and decomposed through a pyrolysis reaction, and the central temperature at this time can be around 400 to 500 degrees.

[0045] Next, exhaust gas is generated inside the pyrolysis treatment room through a pyrolysis reaction, and this exhaust gas is discharged from the pyrolysis treatment room through the first chimney (116) installed on one side of the upper part of the pyrolysis treatment room on the housing, and is discharged to the lower part of the housing as shown in FIG. 2.

[0046] Meanwhile, tar is generated during the thermal decomposition process, and as shown in Fig. 2, this tar is included in the exhaust gas and flows down to the lower part of the housing through the first chimney (116), flows down along the inner wall of the first chimney, and is stored in the tar storage unit (118) through the tar drying heater.

[0047] As shown in Fig. 1, the heater (120) is located at the bottom of the thermal decomposition treatment chamber (114) on the housing and applies heat to the exhaust gas discharged through the first chimney (116) to remove soot contained in the exhaust gas.

[0048] That is, as shown in Fig. 3, the exhaust gas discharged from the pyrolysis treatment room moves through the first chimney and flows into the heater (120) located at the lower part of the housing, and is secondary burned by the heating wire installed inside the heater, thereby removing the soot contained in the exhaust gas.

[0049] At this time, the heating wire (522) installed inside the heater is formed in a spiral shape as shown in FIG. 5 so that the heat generated in the heating wire can be quickly transferred to the inside of the heater, and the internal temperature of the heater for secondary combustion can be set to about 800 degrees.

[0050] Accordingly, soot contained in exhaust gas can be removed through secondary combustion by the heat inside the heater as it passes through the high-temperature interior. At this time, the soot components may be, for example, deflagration or toxic dioxin components, and these soot components are removed through secondary combustion by the heater.

[0051] The second blower (130) blows cooling air into the exhaust gas from which soot has been removed through the heater, thereby cooling the exhaust gas to a temperature below a predetermined level. At this time, the second blower cools the temperature of the exhaust gas to a temperature below a predetermined level and simultaneously creates an air flow in the exhaust gas discharged from the heater. In other words, the exhaust gas that has passed through the heater experiences a weakened air flow, and the second blower creates an air flow so that the exhaust gas can be smoothly discharged through the second chimney.

[0052] In addition, when a negative potential is used as the odor removal unit (131), the air flow generated from the second blower unit (130) allows the exhaust gas to be more easily mixed with the negative potential generated from the negative potential generator, thereby increasing the odor removal efficiency.

[0053] The odor removal unit (131) removes odor from exhaust gas cooled below a certain temperature by cooling air introduced from the second blower unit (130) and discharges it through the second chimney (132).

[0054] At this time, the odor removal unit (131) is a component formed between the heater and the second chimney according to one embodiment of the present invention to additionally remove odor from the exhaust gas from which soot has been removed, thereby allowing more purified exhaust gas to be discharged into the atmosphere.

[0055] This odor removal unit (131) can remove odor from exhaust gas by, for example, mixing a negative potential generated from a negative potential generator with the exhaust gas to remove odor contained in the exhaust gas, or by another method, allowing the exhaust gas to pass through activated carbon to remove odor contained in the exhaust gas, but is not limited thereto.

[0056] The second chimney is formed on the opposite side of the first chimney on the housing and discharges the final exhaust gas from which the odor has been removed from the odor removal unit into the atmosphere.

[0057] Figures 5 to 7 illustrate detailed block configurations of a heater according to another embodiment of the present invention.

[0058] Hereinafter, the operation of each component in a heater according to another embodiment of the present invention will be described in detail with reference to FIGS. 5 to 7.

[0059] The heater (120) is a device that generates heat of about 800 degrees Celsius through a heating wire (522) installed inside as described above, and removes soot contained in the exhaust gas by secondary combustion of the soot contained in the exhaust gas through the heat generated in this manner.

[0060] However, in order to effectively remove soot contained in the exhaust gas from such heaters, it is desirable for the exhaust gas to pass through the heater slowly. That is, for example, in order for the soot contained in the exhaust gas to be effectively removed from the heater, it is desirable for the exhaust gas to pass through the heater for about 4 to 5 seconds.

[0061] Accordingly, in another embodiment of the present invention, the movement speed of the exhaust gas (610) inside the heater is measured, and when the movement speed of the exhaust gas becomes faster and the time it takes for the exhaust gas to pass through the heater becomes faster than the time in the range of 4 to 5 seconds, the movement speed of the exhaust gas passing through the heater is reduced so that the smoke contained in the exhaust gas does not pass through the heater without being sufficiently removed.

[0062] To this end, a heater according to another embodiment of the present invention may further include components such as a speed sensor (530) and an electronic control valve (540) that controls the opening and closing of the second opening (520) of the heater housing.

[0063] The heater housing (512) may be formed with a first opening (510) through which exhaust gas flows in from the first flue (116), as shown in FIG. 5, and a second opening (520) through which exhaust gas passing through the heater is discharged to the second flue (132).

[0064] The electronic control valve (540) is a device installed on the second opening side according to another embodiment of the present invention to control the degree of opening and closing of the second opening, and controls the degree of opening and closing of the second opening (520) according to the speed of movement of exhaust gas passing through the heater measured by the speed sensor (530), so that the speed of movement of exhaust gas passing through the heater is maintained within a preset reference speed range. At this time, the reference speed range may be set so that the time required for exhaust gas to pass through the heater is in the range of 4 to 5 seconds, for example, but is not limited thereto.

[0065] That is, the electronic control valve receives the moving speed of the exhaust gas passing through the heater housing through the speed sensor, and when the moving speed of the exhaust gas exceeds the maximum value of a preset reference speed range, the second opening is gradually blocked as shown in FIG. 6, and the moving speed of the exhaust gas can be controlled to become a value within the reference speed range.

[0066] Meanwhile, as another embodiment, the structure of the heater housing may be changed as in Fig. 7 to ensure that the movement speed of the exhaust gas inside the heater is maintained within a certain reference speed range.

[0067] That is, as another embodiment of the present invention, the heater housing (512) may be formed so that the interior is curved along the curve of the heating wire (522), as shown in FIG. 7, so that the first movement speed of the exhaust gas moving inside the heater housing is lower than the second movement speed of the exhaust gas discharged from the thermal decomposition treatment chamber and moving inside the first chimney.

[0068] As described above, according to one embodiment of the present invention, in a complete combustion type compact self-pyrolysis device, when organic waste, which is a raw material to be pyrolysis treated, is input, the input organic waste is heated and decomposed through a self-pyrolysis reaction to increase the decomposition treatment efficiency of the organic waste, and further, exhaust gas generated during the self-pyrolysis process of the organic waste is secondary combusted in a heater installed in conjunction with the pyrolysis treatment room of the self-pyrolysis device to remove smoke contained in the exhaust gas and purify the exhaust gas, and then an electric precipitator and activated carbon are used in a subsequent odor deodorization unit to remove even odor from the exhaust gas, thereby maximizing the purification level of exhaust gas generated during the self-pyrolysis process of the organic waste.

[0069] Although the present invention has been described with reference to the drawings exemplified above, it is to be understood that the present invention is not limited to the embodiments and drawings disclosed herein, and that various modifications may be made by those skilled in the art within the scope of the technical idea of ​​the present invention. Furthermore, even if the operational effects according to the configuration of the present invention have not been explicitly described while describing the embodiments of the present invention, it is natural that the effects predictable by the corresponding configuration should also be acknowledged.
