Description

Technology Field

[0001] The present invention relates to a livestock manure solid fuel manufacturing device, and more specifically, to a livestock manure solid fuel manufacturing device capable of manufacturing livestock manure solid fuel by recycling livestock manure while suppressing the generation of odors. Background Technology

[0002] In order to utilize livestock manure as a resource, a technology for recycling it by fermenting it is being developed (see Korean Registered Patent 10-2173940). Such technology has the advantage of reducing the burden on subsequent processes by reducing the volume of the manure through drying using the heat generated during fermentation. However, due to the characteristics of the raw material, livestock manure, there is a problem of odor generation, and it is necessary to develop a technology that can suppress such odors.

[0003] Furthermore, when intending to manufacture solid fuel using livestock manure, it was necessary to ensure the fuel had an appropriate moisture content; however, controlling the moisture content of fermented manure produced through fermentation drying presented a problem. This is because fermentation drying is significantly affected by seasonal changes and operating conditions, making it difficult to reduce the moisture content of the manure below a certain level. In particular, utilizing the dried manure itself as solid fuel without undergoing a process of molding it into pellet-like shapes was problematic. While the moisture content could be reduced during the molding process of fermented-dried manure, it was difficult to further reduce the moisture content of the dried manure in its unmolded state.

[0004] Therefore, there is a need to develop a technology that can effectively produce solid fuel using livestock manure without undergoing an additional molding process, while also suppressing odor generation; however, attempts to develop such a technology are hard to find. Prior art literature

[0062] The advantages and features of the present invention and the methods for achieving them will become clear from the embodiments described below in detail together with the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below but may be implemented in various different forms. These embodiments are provided merely to ensure that the disclosure of the present invention is complete and to fully inform those skilled in the art of the scope of the invention, and the present invention is defined only by the scope of the claims.

[0063] Throughout the specification, "and / or" includes each of the mentioned components and all combinations of one or more.

[0064] The terms used in this specification are for describing the embodiments and are not intended to limit the invention.

[0065] Hereinafter, a livestock manure solid fuel manufacturing device, which is an embodiment of the present invention, will be described in more detail with reference to FIGS. 1 to 6. FIG. 1 is a schematic diagram showing a livestock manure solid fuel manufacturing device, which is an embodiment of the present invention. FIG. 2 is a perspective view showing the exterior of an inertial collision type dust collection and humidification unit included in the embodiment shown in FIG. 1. FIGS. 3 to 5 are drawings illustrated to explain the operating principle of the inertial collision type dust collection and humidification unit included in the embodiment shown in FIG. 1. FIG. 6 is a cross-sectional view for explaining an internal heat transfer unit that can be applied to the embodiment shown in FIG. 1.

[0066] As shown in FIG. 1, a livestock manure solid fuel manufacturing device (1), which is an embodiment of the present invention, comprises a fermentation dryer (1-1) and a heating dryer (1-2).

[0067] The fermentation dryer (1-1) includes a fermentation dryer body (10), an air supply unit (30), a manure mixing unit (50), and an inertial collision type dust collection humidification unit (70).

[0068] The main body of the fermentation dryer (10) contains livestock manure (D) and undergoes fermentation drying by heat generated during the process of fermentation by fermentation microorganisms, thereby producing a fermented dried product (FD). Additionally, the air supply unit (30) supplies air (A) to the livestock manure inside the main body of the fermentation dryer, and the livestock manure stirring unit (50) stirs the livestock manure inside the main body of the fermentation dryer.

[0069] In this manner, by containing livestock manure inside the main body of the fermentation dryer, stirring the manure, and supplying air, fermentation by the manure-fermenting microorganisms contained within the main body of the fermentation dryer can be made to proceed more effectively. Since the fermentation speed is faster compared to fermentation without mixing and / or air injection, such fermentation can be referred to as high-speed fermentation. The air may be preheated air. By using air preheated to a preheating temperature (e.g., 20 to 90°C), the temperature of the manure inside the main body of the fermentation dryer can be adjusted to a temperature at which the manure-fermenting microorganisms can proceed with fermentation more effectively. Meanwhile, according to the present invention, since fermentation can be maintained effectively, the energy consumed for preheating the air can also be reduced. The manure-fermenting microorganisms are not limited to those capable of fermenting manure, but may be one or more selected from Bacillus, Lactobacillus, yeast, Bacillus subtilis, and Actinomycetes. Additionally, the manure-fermenting microorganisms may be aerobic microorganisms. Of course, the manure fermentation microorganisms can be contained inside the main body (10) of the fermentation dryer together with the manure.

[0070] Livestock manure is not limited to feces excreted by livestock, and the inclusion of urine is not excluded. Furthermore, the term "livestock" encompasses animals raised, such as cattle, pigs, chickens, and / or ducks.

[0071] Meanwhile, if the manure contains moisture, mesophilic microorganisms (e.g., strains of the genus Bacillus that proceed with fermentation reactions at 40 to 50°C) may proliferate and fermentation reactions may proceed, preferably at 40 to 50°C, and drying of the manure may proceed due to the heat generated from such fermentation reactions. However, if drying is excessive and affects the proliferation of microorganisms, there is a concern that the fermentation reaction may not proceed.

[0072] The main body (10) of the fermentation dryer may be horizontal in addition to the vertical type shown in FIG. 1, and the horizontal type may be a rotary kiln type.

[0073] Livestock manure may be introduced from the top to the bottom of the main body of the fermentation dryer, and air may be introduced from the bottom to the top of the main body of the fermentation dryer. As shown in FIG. 1, livestock manure may be introduced from a livestock manure input section (110), such as a hopper, through a crushing section (111), and then into a livestock manure inlet section (119) formed at the top of the main body of the fermentation dryer in a crushed state. The livestock manure input section is positioned at the front of the fermentation dryer to feed livestock manure raw materials into the fermentation dryer and may include a hopper. Additionally, a crushing section capable of crushing livestock manure raw materials to form crushed material may be positioned between the livestock manure input section and the fermentation dryer. The crushing section may include a cutter for cutting livestock manure raw materials. Livestock manure raw materials crushed by the crushing section have a larger specific surface area, so they may become more suitable for fermentation drying and heat drying.

[0074] Additionally, air (A) can be supplied into the interior of the fermentation dryer body through the air transfer unit (37), the hollow rotating shaft (55), and the hollow rotating bar (53) via the air injection unit (31) formed at the bottom of the fermentation dryer body. The hollow rotating shaft (55) may have a conventional structure in which one end is connected to the rotating motor (51), extends in the longitudinal direction, and the other end is closed. The hollow rotating bar (53) may have a conventional structure in which one end is connected to the empty internal space of the hollow rotating shaft (55), extends in the longitudinal direction, and the other end is closed. It may also have a structure in which an air injection unit (31) is formed to inject air into the interior of the fermentation dryer body by allowing air to flow out between the one end and the other end. The air injection unit (31) may include a nozzle. The rotating motor (51) may have a space formed in its center through which one end of the air transfer unit penetrates and communicates with one end of the hollow rotating shaft. A ball bearing is installed between the central part and the contact part of the air conveying part so as not to interfere with rotational movement. In addition to the hollow rotating bar (53), a mixing blade (57) is additionally installed in the stirring part (50) so that the manure can be stirred more effectively.

[0075] In this manner, since manure and air are supplied into the main body of the fermentation dryer in opposition to each other, fermentation by aerobic microorganisms can proceed more smoothly; at this time, fermentation begins at the bottom of the main body of the fermentation dryer, which can generate heat. The manure is dried by the heat generated by the fermentation reaction at the bottom of the main body, and the drying proceeds from the bottom to the top. Therefore, the manure inside the main body of the fermentation dryer can be divided into a drying layer, a fermentation layer, and a manure input layer, moving from bottom to top. The surface of the manure input layer corresponds to the surface of the manure. If the manure is over-dried inside the main body of the fermentation dryer, the area of ​​the fermentation layer shrinks, preventing the fermentation reaction from occurring sufficiently. As a result, drying does not proceed smoothly. Additionally, drying of the manure surface is facilitated by the layer of air in contact with the surface. The inventors have discovered that, as a result of drying proceeding due to heat generated inside the manure and an external air layer, manure dust is generated on the surface of the manure, and that such dust is a particular cause of odor generation. Therefore, by more effectively suppressing the generation of manure dust on the surface of the manure, the generation of odor can be suppressed. That is, one embodiment of the present invention includes an inertial collision type dust collection and humidification unit (70), thereby enabling more effective suppression of odor generation. The inertial collision type dust collection and humidification unit (70) is directly connected to the exhaust gas discharge unit (13) of the fermentation dryer body (10) and additionally supplies moisture to the exhaust gas discharged from the fermentation dryer body (10). As a result, the generation of manure dust discharged from the exhaust gas discharge unit (13) can be suppressed. This is because the generation of livestock manure dust can be suppressed more effectively by allowing the livestock manure dust contained in the exhaust gas discharged from the main body of the fermentation dryer to be adsorbed to the additional moisture by the moisture supplied from the inertial collision type dust collection humidification unit (70).At this time, the inertia collision type dust collection humidification unit (70) can continuously or intermittently supply additional moisture to the exhaust gas discharged from the fermentation dryer body (10). Furthermore, since the inertia collision type dust collection humidification unit (70) includes a humidification unit body (71), an exhaust gas inlet (73), an exhaust gas outlet (79), a guide unit (75), and a moisture supply unit (77), it can more effectively suppress the generation of livestock manure dust. Below, with reference to FIG. 1 and FIG. 2 to FIG. 5, each component constituting the inertia collision type dust collection humidification unit (70) will be described in more detail.

[0076] The exhaust gas inlet (73) is formed on one side of the humidification unit body (71) and is connected to the exhaust gas discharge unit (13) to introduce exhaust gas discharged from the fermentation dryer body (10) into the humidification unit body. Additionally, the exhaust gas outlet (79) is formed on the other side of the humidification unit body (71) and discharges exhaust gas inside the humidification unit body (71) to the outside. The guide unit (75) is installed between the exhaust gas inlet (73) and the exhaust gas outlet (79) to change the flow direction of the exhaust gas (G) inside the humidification unit body (71) and induce inertial collision of particles contained in the exhaust gas whose flow direction is changed, and the water supply unit (77) directly supplies additional liquid water between the exhaust gas discharge unit (13) and the guide unit (75). That is, the exhaust gas discharged from the main body (10) of the fermentation dryer has its flow direction changed by the guide section (75), and the water supply section (77) can directly supply additional liquid water to the exhaust gas before its flow direction is changed by the guide section (75). As a result, liquid water can be supplied more directly and sufficiently to the livestock manure dust that may be contained in the exhaust gas, so the discharge of livestock manure dust can be suppressed more effectively. This is because the added liquid water can collide more easily with the livestock manure dust, and as a result, its self-weight increases, allowing it to descend more easily. In addition, the flow direction of the exhaust gas (G) inside the main body (71) of the humidification section is changed by the guide section (75), and particles contained in the exhaust gas whose flow direction is changed (e.g., livestock manure dust, droplets formed by adsorbing livestock manure dust to water, etc.) are induced to collide with the surface of the guide section by inertia. In this way, the manure dust can not only come into contact with moisture but also descend by colliding with the surface of the guide section. At this time, if a water film is formed on the surface of the guide section by the water supply unit, it can descend more smoothly. Therefore, the water supply unit (77) can process the manure dust more smoothly by forming a water film on the surface of the guide section (75).The size of the water film may be the size of a single droplet or the size of multiple droplets combined.

[0077] In addition, the water film formed on the surface of the guide section not only prevents contamination of the guide section surface but can also naturally remove existing contamination (e.g., animal waste attached to the guide section surface) during the water film formation process.

[0078] The moisture supply unit (77) may also directly supply additional liquid moisture continuously or intermittently.

[0079] Water can be supplied to the water supply unit (77) from the reservoir (779) by the water supply pipe (775). A pump (776) and a valve (774) may be installed in the water supply pipe (775).

[0080] In addition, the inertial collision type dust collection humidification unit (70) can control the humidity of the surface of the livestock manure contained inside the main body of the fermentation dryer. By controlling the humidity of the surface of the livestock manure, the generation of livestock manure dust on the surface of the livestock manure can be controlled more fundamentally. The humidity may be the humidity of the space between the livestock manure and the main body of the fermentation dryer. In addition, the control may be intended to maintain the relative humidity of the surface of the livestock manure preferably at least 90% to 100% (e.g., relative humidity 90% to 100%), more preferably at least 100% (e.g., relative humidity 100%). At such relative humidity, the generation of livestock manure dust can be suppressed more effectively and the fermentation reaction can be carried out more effectively.

[0081] Humidity control can be achieved more effectively by directly supplying additional liquid water between the exhaust gas discharge section (13) and the guide section (75) through the water supply section (77). This is because, in order to maintain the relative humidity of the manure surface at a high level, it is necessary to maintain the actual water vapor pressure at a high level relative to the saturated water vapor pressure, and it is possible to maintain the actual water vapor pressure at a high level more easily by directly adding liquid water.

[0082] For humidity control, the inertial collision type dust collection humidification unit (70) may further include a moisture transfer unit (76). The moisture transfer unit (76) transfers at least a portion of the moisture supplied from the moisture supply unit (77) into the interior of the fermentation dryer body (10).

[0083] The moisture transfer unit (76) includes a moisture transfer inlet (767), and the moisture transfer inlet (767) may be formed at the bottom of the main body of the humidification unit. A moisture transfer outlet (761) connected to the moisture transfer inlet (767) is connected to the main body of the fermentation dryer (10), so that the moisture collected at the bottom of the main body of the humidification unit moves into the main body of the fermentation dryer by gravity. The moisture moved into the main body of the fermentation dryer in this way descends to the surface of the manure and acts to increase the humidity of the surface of the manure. In this way, by increasing the humidity of the surface of the manure, excessive drying of the manure can be prevented. By preventing excessive drying, the fermentation reaction by the manure fermentation microorganisms can proceed normally, and as a result, drying caused by the heat generated during the fermentation reaction can also proceed normally. That is, the moisture transfer unit (76) may be intended to prevent drying or excessive drying of the manure.

[0084] The moisture supplied from the moisture supply unit (77) is adsorbed by manure dust, etc., and its weight increases, causing it to descend in the direction of gravity, and the moisture that descends in this way is collected at the bottom of the humidification unit body (71).

[0085] In order to better collect and transport the moisture that has fallen in this manner, the humidification unit body includes a moisture collection unit (719), and a moisture transport unit (76) is connected to the bottom of the moisture collection unit. Since the moisture collection unit (719) is formed in the shape of a funnel, droplets (L) falling inside the humidification unit body (71) can collide with the inner surface of the moisture collection unit (719). Droplets colliding in this manner can be more easily guided along the inner surface of the moisture collection unit to the moisture transport unit (76). Inside the moisture collection unit (719), a buoyancy ball (72) is located, which is mounted on the transport moisture inlet (767) of the moisture transport unit (76). The buoyancy ball (72) is formed to be larger than the opening at the bottom of the moisture collection unit connected to the transport moisture inlet, so that it can be mounted on the transport moisture inlet. Since the buoyancy ball (72) is mounted in the water transfer inlet (767), it can prevent the water transfer from being transferred to the water transfer unit until enough water is collected in the water transfer inlet so that the buoyancy ball can float. At this time, the water transfer unit (76) includes a flue gas control unit (764) that controls the movement of flue gas from inside the main body of the fermentation dryer to inside the main body of the humidification unit, thereby suppressing the buoyancy ball from being affected by the flue gas inside the main body of the fermentation dryer and, if necessary, allowing a sufficient amount of water to be transferred into the main body of the fermentation dryer. At this time, the buoyancy ball (72) prevents the flue gas control unit (764) from being directly contacted by falling droplets (L), thus preventing contamination caused therefrom. The flue gas control unit (764) is not limited as long as it can control the flow of fluid, and may be a valve (e.g., a butterfly or gate-type automatic valve). Hereinafter, such a process will be explained in more detail with reference to FIGS. 3 to 5.FIG. 3 is a diagram showing the initial state in which a liquid droplet collides inside the moisture collection section of the humidification unit body, FIG. 4 is a diagram showing the state in which water accumulates at the bottom inside the moisture collection section and causes the buoyancy ball to float, FIG. 5 is a diagram showing the internal state in which the exhaust gas control section is opened to allow the water collected at the bottom of the moisture collection section to pass through to the moisture transfer section. As shown in FIG. 3, in the initial state in which a liquid droplet (L) falls (dotted arrow) and collides with the moisture collection section of the humidification unit body, the exhaust gas control section (764) blocks the movement of exhaust gas from inside the fermentation dryer body body to inside the humidification unit body, and the buoyancy ball is also mounted on the transfer water inlet section (767). When liquid droplets accumulate at the bottom of the moisture collection section and water (W) accumulates, the buoyancy ball (72) is floated (see FIG. 4). At this time, by opening the exhaust gas control section (764), the water accumulated at the bottom of the moisture collection section is passed through the moisture transfer section (76) to move water (solid arrow) into the main body of the fermentation dryer (see FIG. 5). At this time, the water (W) may be water containing manure dust. When the movement of water is finished, the exhaust gas control section is closed and the buoyancy ball is placed in the water transfer inlet. With this configuration and operation method, water can be supplied more effectively into the main body of the fermentation dryer only when necessary, thereby effectively controlling the humidity of the surface of the contained manure.

[0086] Meanwhile, to prevent the deterioration of the function of the inertia collision type dust collection humidification unit, a connecting part (137) connecting the exhaust gas discharge part (13) of the fermentation dryer body (10) and the exhaust gas inlet part (73) of the inertia collision type dust collection humidification unit (70) may have a thermal insulation part (not shown). The thermal insulation part may be made of an insulating material that surrounds the outside of the connecting part, which is made of a pipe. Since the thermal insulation part can suppress the occurrence of condensation in the connecting part, it is possible to avoid the deterioration of the function of the inertia collision type dust collection humidification unit by preventing the condensation from obstructing the gas flow discharged from the exhaust gas discharge part.

[0087] Additionally, the exhaust gas outlet (79) of the inertial collision type dust collection humidification unit (70) is connected to the wet exhaust gas treatment unit (90) to remove odor substances. Such a wet exhaust gas treatment unit (90) may include an acid scrubbing tower (91) for treating odor substances, and the acid scrubbing tower (91) can treat basic odor substances such as ammonia using an acid such as sulfuric acid or phosphoric acid. Sludge generated in the wet exhaust gas treatment unit (90) during the treatment process can be transported to the main body of the fermentation dryer (10) by the sludge transport unit (93) and treated again. One end of the sludge transport unit (93) is connected to the livestock manure transport unit (115) so that the sludge can be transported into the main body of the fermentation dryer (10) together with the livestock manure. The sludge return section (93) includes a pump (98) and a valve (96) to control the amount of return. One side of the acid scrubbing tower (91) may be connected to the exhaust gas transfer pipe (95), and the other side may be connected to an exhaust pipe (97) that discharges gas after odor treatment. A valve (94) may be installed in the exhaust gas transfer pipe (95), and a pump (99) may be installed in the exhaust pipe.

[0088] With this configuration, the fermented dried material, which is more effectively fermented and dried, is discharged to the fermented dried material discharge section (199) formed on the other side of the main body of the fermented dryer. That is, the livestock manure introduced through the livestock manure inlet section (119) formed on one side of the main body of the fermented dryer undergoes a fermentation and drying process inside the main body of the fermented dryer to form a fermented dried material, and then undergoes a drying process in the heating dryer (1-2) after being discharged to the fermented dried material discharge section (199) formed on the other side of the main body of the fermented dryer. This allows the moisture content to be sufficiently reduced without an additional molding process, so that it can be used as solid fuel in its current state.

[0089] The heating dryer (1-2) includes a heating dryer body (20), a heating air supply unit (300), a fermented dried material stirring unit (60), and an internal heating unit (40). Through the organic combination of such configurations, the moisture content of the fermented dried material formed in the fermentation dryer can be lowered more easily, and the heated dried material itself can be used directly as livestock manure solid fuel without undergoing a separate molding process. Therefore, the livestock manure solid fuel manufacturing device of the present invention can more effectively suppress the generation of odors by suppressing the generation of livestock manure dust during the process of drying livestock manure by fermentation drying, and can also manufacture livestock manure solid fuel that can be utilized as solid fuel without undergoing an additional molding process.

[0090] The heating dryer body (20) receives the fermented dried product (FD) generated and discharged from the fermentation dryer (1-1) and dries it by heating to produce a heated dried product. At this time, the heating temperature is not limited as long as it can produce a fermented dried product, but for example, it may be 50 to 130°C. In addition, the livestock manure may have a moisture content of 50 to 75% by weight, the fermented dried product may have a moisture content of 25 to 35% by weight, and the heated dried product may have a moisture content of 20% by weight or less. Livestock manure solid fuel can be manufactured more effectively within such a range.

[0091] In the main body (20) of the heating dryer, a fermented dried material inlet (217) is formed on one side, connected by a fermented dried material discharge section (199) and a fermented dried material transport section (19). The fermented dried material transport section (19) is not limited as long as it can move the fermented dried material, but, for example, it may be formed to include a conveyor belt or a screw, etc., so that even viscous fermented dried material can be easily transported. In this way, the fermented dried material transported by the fermented dried material transport section can be fed into the main body of the heating dryer through the fermented dried material inlet (217) and received.

[0092] The fermented dried material contained within the main body of the heating dryer is dried more effectively by the heating air supply unit (300), the fermented dried material stirring unit (60), and the internal heating unit (40). Since this drying is carried out by controllable mechanical energy and thermal energy rather than relying on fermentation drying by microorganisms, the moisture content of the fermented dried material can be controlled more easily. At this time, since the fermented dried material contained within the main body of the heating dryer has reduced volume and moisture while using relatively less energy, the energy consumption of the heating dryer can also be reduced.

[0093] The heated air supply unit (300) can reduce the moisture content of the fermented dried material by supplying heated air (HA) that comes into direct contact with the fermented dried material contained inside the main body of the heated dryer. The heated air supply unit (300) includes a main heated air supply unit (310) and may further include a sub-heated air supply unit (320). The main heated air supply unit (310) is a heated dryer entity It may include a main heating air supply pipe (63) extending from the center toward the inner wall.

[0094] At this time, the fermented dried material stirring unit (60) can mix the heated air and the fermented dried material more effectively by stirring the fermented dried material (FD) contained inside the main body of the heating dryer. At this time, the fermented dried material stirring unit (60) can stir the fermented dried material more effectively by including a rotating shaft (65) and a mixing blade (67) extending outward from the rotating shaft. The rotating shaft (65) may be a hollow rotating shaft of a conventional structure, with one end connected to a rotating motor (61), extending in the longitudinal direction, and the other end closed. At this time, the main heated air supply pipe (63) has one end connected to the rotating shaft (65) and can move according to the rotation of the rotating shaft. Specifically, the main heating air supply pipe (63) may be formed of a hollow rotating bar with a conventional structure in which one side is connected to the empty internal space of the hollow rotating shaft and the other side is closed, and a heating air injection part (301) is formed to inject heating air (HA) into the main body of the heating dryer by discharging heating air (HA) between the one side and the other side. The heating air injection part (301) may include a nozzle. The rotary motor (61) may have a space formed in its center through which one side of the heating air transfer part (307) passes and communicates with one side of the hollow rotating shaft. A ball bearing may be installed between the center and the contact part of the heating air transfer part so as not to interfere with rotational movement.

[0095] The sub-heating air supply unit (320) may include a sub-heating air supply pipe (323) extending in a central direction from the inner wall of the heating dryer body. The sub-heating air supply pipe may be formed as a hollow bar of a conventional structure extending in a central direction from the inner wall of the heating dryer body and closed at the other end, and may have a structure in which one end is connected to a heating air transfer unit (327) and a heating air injection unit (321) is formed to inject heating air into the heating dryer body by discharging heating air (HA') between the one end and the other end. The heating air injection unit (321) may include a nozzle. In this way, the sub-heating air supply unit, which has a different structure from the main heating air supply unit, may be formed at a different location from the main heating air supply unit. Specifically, a sub-heated air supply pipe is positioned above the main heated air supply pipe. For example, the sub-heated air supply pipe (323) may be located in the upper half of the main body of the heated dryer (20), and the main heated air supply pipe may be located in the lower half of the main body of the heated dryer. The upper half may refer to a portion of 50% or more of the height of the heated dryer, and the lower half may refer to a portion of less than 50% of the height of the heated dryer. By supplying heated air to a wide space through the main heated air supply pipe, the fermented dried material at the bottom is dried more quickly, and the fermented dried material at the top, which has been dried relatively further, is additionally dried by the sub-heated air supply pipe, thereby reducing energy consumption and effectively proceeding with drying.

[0096] Additionally, the internal heating unit (40) transfers heat to the fermented dried material contained within the main body of the heating dryer by contacting it while one side is fixed inside the main body of the heating dryer. The internal heating unit is not limited to, as long as it can transfer heat to the fermented dried material contained within the main body of the heating dryer by contacting it while one side is fixed inside the main body of the heating dryer, but may include one or more selected from a heating wire, a heating lamp, and / or a heat fluid (e.g., steam, heated air, and / or heat oil). Furthermore, the internal heating unit may use heat generated by one or more selected from a fossil fuel generator, a nuclear generator, a wind generator, a tidal generator, a geothermal generator, a photovoltaic generator, photovoltaic heat (PVT), and a heat pump as a heat source.

[0097] For example, the internal heat transfer section (40) may be formed to include a heat fluid transfer pipe (45) through which a heat fluid (T) flows, as shown in FIG. 6. At this time, the heat fluid refers to a fluid capable of transferring heat regardless of its name, and is not limited to any fluid capable of transferring heat. For example, the heat fluid may be a heat transfer oil, synthetic oil, mineral oil, glycol aqueous solution, water, steam, gas and / or air. Such a heat fluid may be introduced into the heat fluid transfer pipe in a heated state. In the process where the heat fluid (T) becomes a low-temperature heat fluid (LT) through the heat fluid discharge section (49) of the heat fluid discharge pipe (47) after passing through the heat fluid transfer pipe (45), heat exchange occurs and the heat fluid (HT) is introduced into the heat fluid inlet section (41) of the heat fluid inlet pipe (43) (black arrow). In this case, the low-temperature thermal fluid refers to a thermal fluid with a temperature lower than that of the high-temperature thermal fluid. Additionally, the high-temperature thermal fluid refers to a thermal fluid with a temperature higher than that of the fermented dried material, and can transfer heat to the fermented dried material during the heat transfer process to induce drying.

[0098] Additionally, the internal heating element (40) may be formed to include a heating wire (not shown) or a heating lamp (not shown) that generates heat by electric power.

[0099] Such an internal heating unit is positioned in a part that is difficult for the heated air supplied by the heated air supply unit to reach, thereby allowing the entire fermented dried material to be dried. At this time, at least a portion of the internal heating unit (40) is positioned below the mixing blade (67), so that the fermented dried material located between at least a portion of the internal heating unit and the mixing blade can be moved by the change in position of the mixing blade. By moving the fermented dried material in this way, the internal heating unit can come into contact with more of the fermented dried material.

[0100] In addition, one embodiment of the present invention may include an external heat transfer member (400) that contacts at least a portion of the outer surface of the main body of the heating dryer and transfers heat to at least a portion of the outer surface of the main body of the heating dryer. That is, it may include an external heat transfer member that contacts at least a portion of the outer wall of the main body of the heating dryer and transfers heat to the outer wall of the main body of the heating dryer. The external heat transfer member may be formed on the bottom surface and / or lower side of the main body of the heating dryer. The lower part may be at least a portion of the lower half of the side connected to the bottom surface. By such an external heat transfer member, heat loss from the main body of the heating dryer can be prevented, and as a result, the drying of the fermented product can be performed more effectively.

[0101] In addition, the external heating unit may also include components capable of generating heat similar to those of the internal heating unit, and the heat source may also be of the same type. That is, the internal heating unit and / or the external heating unit may include one or more selected from heating wires, heating lamps, and / or heat fluids (steam, heated air, or heat transfer fluid). Furthermore, the internal heating unit and / or the external heating unit may use heat generated by one or more selected from fossil fuel generators, nuclear generators, wind turbines, tidal generators, geothermal generators, photovoltaic generators, solar heat, and heat pumps as a heat source.

[0102] At this time, a sub-heating air supply pipe (323) may be positioned between the main heating air supply pipe (63) and the mixing blade (67), and an internal heating unit (40) may be positioned between the mixing blade (67) and the sub-heating air supply pipe (232). Heated air is introduced from the main heating air supply pipe rotating in the lower half of the heating dryer body to dry the fermented dried material and move upward, while heated air is introduced from the fixed sub-heating air supply pipe in the upper half of the heating dryer body to mainly dry the fermented dried material in the upper half, and above that, the fermented dried material is dried by the internal heating unit, and it is possible to enhance the heat transfer effect of the internal heating unit by the mixing blade. At this time, the effects of the heating air supply unit and the heating unit can also be doubled by the stirring effect of the fermented dried material stirring unit.

[0103] Accordingly, according to the present invention, the heated air supply unit (300), the fermented dried material stirring unit (60), the internal heat transfer unit (40), and the external heat transfer unit (400) are organically combined to more effectively dry the fermented dried material, thereby enabling the production of livestock manure solid fuel that can be used directly as solid fuel without an additional molding process.

[0104] Additionally, the exhaust gas discharge section (23) of the heating dryer (1-2) is connected to the dry exhaust gas treatment section (80) to remove contaminants such as dust discharged from the heating dryer. The dry exhaust gas treatment section includes a dry dust collector (81), such as a filter dust collector or a cyclone, and one side of the dry dust collector (81) may be connected to an exhaust gas transfer pipe (85), and the other side may be connected to an exhaust pipe (87). A pump (89) may be installed in the exhaust pipe. One side of the exhaust gas transfer pipe (85) is connected to the exhaust gas discharge section (23), and the other side is connected to the dry dust collector (81), and a valve (84) may be installed. This is because the exhaust gas discharged from the heating dryer (1-2) is in a dry state with low moisture content, so it can be treated by the dry exhaust gas treatment section (80).

[0105] Meanwhile, a heat-dried material discharge section (299) is formed on the other side of the heat-dried body to discharge the heat-dried material. For example, the heat-dried material that has undergone drying within the heat-dried body (20) can be discharged through the heat-dried material discharge section (299) at the bottom of the heat-dried body and transferred to the solid fuel storage section (29) via the heat-dried material transfer section (295). Since the heat-dried material can be used as livestock manure solid fuel without undergoing an additional molding process, it can be stored in the solid fuel storage section. The heat-dried material transfer section (295) may include a conveyor belt, etc.

[0106] Additionally, the air supply unit (30) includes an air transport unit (37), and the heated air supply unit (300) includes a heated air transport unit (307, 327). The air transport unit (37) and the heated air transport unit (307, 327) are connected to a single air supply duct (337) which is a loop pipe through which internal gas can circulate along the pipe. Air can be supplied to the air supply duct (337) by a blower (339). Due to this structure, deviations in air supply can be suppressed, and multiple livestock manure solid fuel manufacturing devices can be operated effectively. Furthermore, it goes without saying that the number of air supply ducts (337) can increase as the number of air supply units and heated air supply units increases. That is, a plurality of air supply units and heated air supply units are connected to one air supply duct, and another plurality of air supply units and heated air supply units are connected to another air supply duct, so that air can be supplied more effectively to multiple air supply units and heated air supply units.

[0107] At this time, the heated air transfer unit (307, 327) may include a heater (305, 325) for heating the air being transferred and a valve (304, 324) for controlling the flow rate. Additionally, the air transfer unit (37) may include a heater (35) for preheating the air being transferred and a valve (34) for controlling the flow rate. At this time, the heater may refer to a heat supply device. The heater may also include a component capable of generating heat, such as an internal heating unit and / or an external heating unit, and the heat source may also be of the same type. That is, the heater, the internal heating unit and / or the external heating unit may include one or more selected from a heating wire, a heating lamp, and / or a heat fluid (steam, heated air, or heat transfer fluid). In addition, the heater, internal heating unit, and / or external heating unit may use heat generated by one or more selected from fossil fuel generators, nuclear generators, wind turbines, tidal generators, geothermal generators, photovoltaic generators, solar thermal energy, and heat pumps as a heat source. At this time, the electricity produced by the fossil fuel generator, nuclear generator, wind turbine, tidal generator, geothermal generator, photovoltaic generator, solar thermal energy, and / or heat pump may not only serve as a heat source but may also be used to supply power to blowers and other electrical equipment. Furthermore, the heat generated by the fossil fuel generator, nuclear generator, wind turbine, tidal generator, geothermal generator, photovoltaic generator, solar thermal energy, and / or heat pump may be supplied directly to heating units or heating devices such as the heater, internal heating unit, and / or external heating unit, or stored in a heat storage tank and supplied to heating units or heating devices when necessary. In this case, the heat storage tank may be a tank that stores a heat fluid such as hot water.

[0108] Additionally, the blower (339) can be placed inside the soundproof room (331) to suppress noise generation. The soundproof room is a structure that includes walls and a roof to suppress noise from escaping to the outside, and may be a structure that allows communication with the outside through doors or windows. The materials or structure of the walls and roof are not limited as long as they suppress noise, and, of course, may include sound-absorbing materials if necessary. The soundproof room can preferably be located underground. Since the blower is located underground, noise that livestock can hear can be suppressed more effectively. In particular, even if a livestock manure solid fuel manufacturing device is installed around a livestock barn where manure is generated, noise is effectively suppressed, so the impact on the livestock in the barn can be minimized. At this time, the blower (339) can be connected at a location separated from the air supply duct (337) by a connecting pipe (335). Explanation of the symbols
