Description

The method for treating highly infectious animal carcasses {The method for treating highly infectious animal carcasses}

The present invention relates to a method of treating infectious animal carcasses generated in livestock farms and animal hospitals, etc., and infectious wastes generated in other hospitals, and in particular, to a method for manufacturing fuel by treating highly infectious animal carcasses with very high infectivity. will be.

Representative highly infectious infectious diseases that have been designated as the first legal animal epidemic in Korea include foot and mouth disease and Avian influenza. Foot and mouth disease is a disease in which blisters form around the mouth and hooves of cows, pigs, goats, deer, and camels with two hoofs. It is a legal infectious disease, and avian influenza (Avian influenza) is a viral respiratory disease that infects chickens and ducks, and is also called birdflu, and avian influenza is an infectious disease that can infect people beyond species. In the event of these foot-and-mouth disease or avian influenza, all infected livestock are killed and disposed of, so the damage to livestock farms is severe, as well as economic losses, such as the lack of national credit, such as restrictions on international trade of animals and livestock products. The incidence of these infectious diseases is increasing every year around the world, and most of them have an increasing number of killing methods that urgently bury livestock carcasses. Since 2010, the cost of killing livestock infected with infectious diseases has reached 4 trillion won.

In advanced countries, incineration is a rule, and in case of unfavorable conditions, only limited burial is allowed in some areas, and burial is prohibited under normal conditions. However, most of Korea disposes of highly infected livestock by burial.

Pathogens (fungi, bacteria, viruses, prions) may remain in the buried site for a long period of time during burial of infected animal carcasses, contamination of nearby soil and groundwater by leachate from the burial site due to negligence of follow-up management, pathogenic microorganisms, etc. There is a possibility of this leaking. In addition, as the buried land has reached saturation, local governments and farmers are also demanding improvement of treatment methods.

In 2015, the notice on “Livestock Infectious Diseases That Can Recycle Livestock Carcasses” was revised, and carcasses suffering from infectious diseases such as foot-and-mouth disease and AI (bird flu) can be recycled through composting. As a method of treating infected animals other than the burial method, the rendering treatment method of dead livestock according to Korean Patent Publication No. 10-2118717, anaerobic digestion of Korean Patent Publication 10-2018-0134265, and composting of Korean Registered Patent Publication 10-1914769 (composting), alkaline hydrolysis of Korean Patent Publication No. 10-1360524, and lactic acid fermentation of Korean Patent Publication No. 10-1450752 are known.

However, the above-described conventional techniques related to the treatment method and apparatus of infectious waste to date have been related to a method of using the treated carcass remains as compost or feed raw material, but farmers have been concerned with feed, compost, and feed made from carcasses of infectious animals. Since there is a problem of avoiding fertilizers, these prior techniques have not been put into practical use.

On the other hand, PCT/JP2006/319269 discloses a "organic waste treatment system using high temperature and high pressure", and mentions animal carcasses as a type of organic matter treated at high temperature and high pressure, but there is no mention of treatment time. The reaction temperature and pressure were above 230 ℃ and 3 MPa, so the temperature and pressure of the operating conditions were too high, so the equipment manufacturing cost was very expensive and the operation cost was also high, resulting in poor economic efficiency. In addition, there is a mention that the treated material is used as a fuel, but a fuel manufacturing method with low economical efficiency is used, such as drying the treated product by supplying water vapor again using a device to use it as fuel.

In addition, in Japanese Patent Publication No. 4,751,977 on a method of treating organic matter by subcritical water treatment, high-temperature and high-pressure water vapor is injected into a treatment device to treat the object at a temperature of about 230°C to 260°C and a pressure of about 3 MPa. A method of treating is disclosed, and Korean Patent Laid-Open No. 10-2008-0090832 discloses a method of treating food waste and plastic mixtures at 200 to 250° C. and 1.55 to 3.98 MPa by injecting high temperature and high pressure water vapor into a treatment device. A fueling device is disclosed, and Korean Patent Publication No. 10-0572301 discloses a method of treating with saturated steam around 170-250° C. for about 1 hour, but the treatment time is long, 　Korean Patent Publication No. The animal carcass processor of No. 10-1714043 is a device that treats animal carcasses at a temperature of 140∼160℃ with a pressure of 3.5∼5 kg/㎠. After cooking the processed material at low pressure, the processed material is crushed using a crusher or a pulverizer. Or, a method of pulverizing is disclosed.

In the prior art, since the object to be treated is treated at a high temperature and high pressure in order to treat organic substances, a very expensive treatment device capable of withstanding high temperature and high pressure is required, and operation costs are excessively high. , There was a problem that the treatment period was longer than 2 hours and 30 minutes.

In addition, the prior art has a problem in that a secondary treatment must be performed when the temperature and pressure are low in order to treat animal carcasses, and there is a problem that the treatment period takes a long time to reach 3 hours.

The present invention is to improve the problems of the prior art described above. First, treatments such as carcasses of highly infectious animals infected by infectious diseases or killed by infectious diseases are not used for feed or fertilizer, but for thermal power plants or firewood boilers. It is intended to provide a method of manufacturing fuel by treating carcasses of highly infectious animals that can be used as fuel.

Second, in addition, the present invention does not require an expensive treatment device by treatment at a relatively low temperature and low pressure compared to the prior art in order to treat organic matter, etc., and the treatment period is less than 1 hour. It is to provide a method of manufacturing fuel by treating carcasses of highly infectious animals that can be greatly shortened by.

Third, and the present invention, while treating highly infectious animal carcasses by low temperature and low pressure, secondary treatment is not required, as well as highly infectious animal carcasses that can greatly shorten the treatment period to a level of less than 1 hour. It is to provide a method of manufacturing fuel by processing.

Fourth, in addition, the present invention is a new source of infection by scattering the crushed or pulverized object and tissues, blood and pathogens that occur when the object to be treated, such as a highly infectious animal carcass, etc., are scattered. It is intended to provide a method of manufacturing fuel by processing highly infectious animal carcasses that can treat highly infectious animal carcasses in a safe, simple, fast and large amount that can be prevented.

The present invention is an object of the invention described above, that is, to provide a method for producing a fuel that shortens the treatment time to less than 1 hour by treating the carcasses of highly infectious animals at low temperature and low pressure so that secondary treatment is not required. In order to achieve it, it has the following configuration.

That is, the configuration of the present invention includes the steps of supplying the highly infectious animal carcasses transported by the conveyor to the compressor, supplying the highly infectious animal carcasses compressed by the compression roller of the compressor to the inner tank through the inlet, and the high pressure boiler. Heating the inner tank by supplying the saturated steam generated by the inside of the outer tank, while stirring the supplied carcasses of highly infectious animals with a stirrer, the saturated steam generated by the high-pressure boiler is superheated and saturated by a heating device. The step of hydrothermal carbonization of animal carcasses by injecting water vapor directly into the inner tank, supplying cooling water to the outer tank to cool the inner tank, opening the gas discharge valve of the inner tank to discharge exhaust gas, and releasing the compressed air compressed by the compressor. The step of cooling the inner tank by supplying it to the inner tank, deodorizing the exhaust gas discharged in the cooling step with a deodorizing device and then discharging the exhaust gas, opening the outlet opening and closing device to discharge the hydrothermal and highly infectious animal carcasses The composition is a method of manufacturing fuel by treating carcasses of highly infectious animals comprising the step of discharging into the furnace.

Next, the process of the method of manufacturing fuel by processing highly infectious animal carcasses will be described in more detail step by step, the "(1) step of supplying highly infectious animal carcasses transported by a conveyor to a compressor" of the present invention It relates to the step of rapidly supplying the transported carcasses of highly infectious animals to a compressor by means of a conveyor.

In addition, the "(2) step of supplying the high-infectious animal carcasses compressed by the compression roller of the compressor to the internal tank through the inlet" of the present invention is one of the characteristic configurations of the present invention differentiated from the prior art. The compression rollers of the infectious animal are not crushed or crushed, and the continuous compression roller is not pulverized and supplied quickly, and the compression roller adjacent to the inlet is configured to be smaller than the diameter of the inlet, so that the diameter of the inlet is smaller than the diameter of the inlet. Compressed, highly infectious animal carcasses quickly enter the internal tank. For this reason, highly infectious animal carcasses are not crushed or crushed, and pathogens scatter and become a new source of infection, yet show a remarkable effect of rapidly supplying highly infectious animal carcasses.

According to the treatment method according to the prior art, in the case of a treatment method that is crushed or pulverized through a crusher or a pulverizer and then supplied to the reactor through an inlet, pathogens are scattered from highly infectious animal carcasses during crushing or pulverization, resulting in a new infection. In the case of a treatment method that is supplied to the reactor through the inlet without being crushed or crushed, the cause of high infectious animal carcasses is supplied to the reactor through the inlet by manpower. In addition to the disadvantage of contact, there was a disadvantage that the supply speed was very slow due to the supply by manpower. In the present invention, “(2) the carcasses of highly infectious animals compressed by the compression roller of the compressor are supplied to the internal tank through the inlet. The disadvantages of the prior art have been solved by "stepping to".

In addition, the “(3) step of heating the inner tank by supplying the saturated steam generated by the high pressure boiler to the inside of the outer tank” of the present invention is to generate saturated steam at a temperature of 230 to 249°C and a pressure of 2.85 to 4.06 MPa. It is a step of heating the inner tank so that the temperature of the inner tank is 150~200℃ and the pressure is 0.45~1.59 MPa by supplying the saturated steam generated by the high-pressure boiler with a capacity of 20 to 30 minutes to the outer tank. Saturated steam generated by the high-pressure boiler is supplied to the inside of the external tank for 20 to 30 minutes, and the internal tank is heated by the saturated steam so that the temperature reaches 150 to 200°C and the pressure reaches 0.45 to 1.59 MPa, which will be described later. By allowing the “(4) hydrothermal carbonization step” to proceed, condensate water does not occur in the internal tank, so that the “(4) hydrothermal carbonization step” proceeds very quickly and efficiently in 20 to 30 minutes. Here, it is more preferable to heat the inner tank so that the temperature of the inner tank is 160 to 180 °C and the pressure is 0.63 to 1.0 MPa.

In addition, while stirring the supplied highly infectious animal carcasses of the present invention with a stirrer, the saturated steam generated by the high-pressure boiler directly sprays the superheated saturated steam heated by the heating device into the inner tank to destroy the animal carcasses. The step of hydrothermal carbonization” is, while agitating the carcasses of highly infectious animals supplied to the internal tank with a stirrer, the saturated steam generated by the high-pressure boiler is heated by a heating device to have a temperature of 190 to 249 °C and a pressure of 1.28 to 4.06 MPa. It is a step of hydrothermal carbonization for 20 to 30 minutes at a temperature of 160 to 240°C and a pressure of 0.63 to 3.41 MPa by spraying superheated saturated steam directly into the inner tank.

At this time, it is more preferable to hydrothermalize the animal carcasses at a temperature of 180 to 230 °C and a pressure of 1.02 to 2.85 MPa by spraying superheated saturated steam with a temperature of 200 to 240 °C and a pressure of 1.59 to 3.41 MPa directly to the inner tank. It is most preferable to hydrothermalize animal carcasses at a temperature of 190 to 220 ℃ and a pressure of 1.28 to 2.37 MPa by directly spraying superheated saturated steam with a pressure of 1.95 to 2.85 MPa at 210 to 230 ℃ to the inner tank. Since these temperatures and pressures are significantly lower than in the prior art, for this reason, energy is greatly saved, and the treatment time is significantly shortened to 20 minutes compared to 1 hour to 1 hour and 30 minutes of the prior art, and hydrothermal carbonization compared to the prior art. The carbonization degree of the generated fuel is greatly improved, and the calorific value reaches 6,100 KJ/kg, which shows a remarkable effect of 133% increase compared to the calorific value of the fuel generated by the prior art 4,600 KJ/kg.

In addition, "(5) of the present invention, while cooling the inner tank by supplying cooling water to the outer tank, opening the gas discharge valve of the inner tank to discharge exhaust gas, and supplying compressed air compressed by the compressor to the inner tank, The step of cooling “(a) cooling with cooling water and at the same time (b) discharging exhaust gas by opening the gas discharge valve of the inner tank and supplying compressed air compressed by the compressor to the inner tank, It is a process that makes cooling highly efficient by performing two cooling methods for cooling at the same time.

In the present invention, by adopting two cooling steps, in the previous step “(4) hydrothermal carbonization”, the generated fuel (highly infectious animal carcasses after hydrothermal carbonization) are rapidly transferred to the inner tank in high heat and high pressure conditions. As described below, “(6) the step of discharging the exhaust gas after deodorizing the exhaust gas discharged in the cooling step with a deodorizing device” and “(7) opening the outlet opening/closing device to be hydrothermal carbonized. The step of discharging the carcasses of highly infectious animals to the discharge port can be carried out quickly, which has a remarkable effect that can greatly shorten the entire treatment process.

That is, the cooling step of the prior art is provided with only one simple step of cooling the inner tank by supplying cooling water to the outer tank. The step of cooling is “(a) cooling by cooling water and at the same time (b) opening the gas discharge valve of the inner tank to discharge exhaust gas, and supplying compressed air compressed by the compressor to the inner tank to cool the inner tank. By simultaneously adopting the "branch cooling method", the cooling treatment time is greatly shortened to 20 to 30 minutes, and the cooling treatment time is reduced by 3 to 6 times.

Here, the "(5) cooling step" is cooling the inner tank by supplying cooling water to the outer tank, It is more preferable to open the gas discharge valve of the inner tank to discharge exhaust gas, and to cool the inner tank to a temperature of 80 to 120 ℃ and a pressure of 0.05 to 0.28 MPa by supplying compressed air compressed by the compressor to the inner tank for 20 to 30 minutes. It is most preferable to cool the inner tank at a temperature of 80 to 120°C and a pressure of 0.05 to 0.28 MPa.

In addition, the "(6) step of discharging the exhaust gas after deodorizing the exhaust gas discharged in the cooling step with a deodorizing device" of the present invention is, as described in the previous step, by opening the gas discharge valve of the inner tank to exhaust the exhaust gas. The gas is discharged, and the compressed air compressed by the compressor is supplied to the internal tank for 20 to 30 minutes to be discharged, so the time required for discharge is greatly shortened compared to that of the conventional technology to discharge the exhaust gas according to its own pressure. In addition, the present invention exhibits a remarkable effect in that the exhaust gas is deodorized by a deodorizing device and then discharged.

Finally, the "(7) step of discharging the hydrothermal and highly infectious animal carcasses to the discharge port by opening the discharge port opening/closing device" is the same as the known discharge step.

In the present invention, first, treatment of highly infectious animal carcasses to be used as fuels such as thermal power plants or firewood boilers, not for feed or fertilizer, to be treated such as highly infectious animal carcasses infected by infectious diseases or died from infectious diseases. This is to show the effect of providing a method of manufacturing fuel.

Second, in addition, the present invention does not require an expensive treatment device by treatment at a relatively low temperature and low pressure compared to the prior art in order to treat organic matter, etc., and the treatment period is less than 1 hour. It shows the effect of providing a method of manufacturing fuel by processing highly infectious animal carcasses that can be greatly shortened by.

Third, and the present invention, while treating highly infectious animal carcasses by low temperature and low pressure, secondary treatment is not required, as well as highly infectious animal carcasses that can greatly shorten the treatment period to a level of less than 1 hour. It is to show the effect of providing a method of manufacturing fuel by processing.

Fourth, in addition, the present invention is a new source of infection by scattering the crushed or pulverized object and tissues, blood and pathogens that occur when the object to be treated, such as a highly infectious animal carcass, etc., are scattered. It shows the effect of providing a method of manufacturing fuel by treating highly infectious animal carcasses that can treat highly infectious animal carcasses in a safe, simple, fast and large amount that can be prevented.

In the method of manufacturing fuel by processing the carcasses of highly infectious animals of the present invention, the carcasses or animals infected with infectious diseases are put into a reactor that can be sealed, and the carcasses are hydrothermally carbonized in a short time using saturated water vapor at high temperature and high pressure, so that the generation of odor is almost impossible. No, it minimizes the generation of air pollutants such as dioxin, and can be completely sterilized, and the object to be treated can be recycled as fuel, so it is possible to manufacture fuel by processing highly infectious animal carcasses that can be completely treated without polluting the environment. It is to show the effect of providing a way to do it.

In addition, since the present invention is configured as a mobile type, it can be loaded into a vehicle and quickly moved to the field, and animals or corpses infected with infectious diseases can be completely treated in a short time and converted into fuel. Highly infectious medical waste and biomass such as waste wood and waste paper, organic waste, waste plastic, household waste, sewage sludge, livestock waste, and food waste. It shows the effect of providing a method of making fuel.

In more detail, the process steps of the method of manufacturing fuel by processing highly infectious animal carcasses will be described in more detail, "(1) supplying the highly infectious animal carcasses transported by the conveyor 600 to the compressor 500 of the present invention. ”Relates to the step of rapidly feeding the transported carcasses of highly infectious animals to the compressor 500 by the conveyor 600.

And, "(2) compression rollers of the compressor 500 (first compression roller 520, second compression roller 530, third compression roller 540, fourth compression roller 550) of the present invention The step of supplying the highly infectious animal carcasses compressed by the inlet 105 to the inner tank 102 through the inlet 105 is one of the characteristic configurations of the present invention differentiated from the prior art, and the compression rollers of the compressor 500 (The first compression roller 520, the second compression roller 530, the third compression roller 540, the fourth compression roller 550) by the high-infectious animal carcasses are not crushed or crushed, a compression roller that is continuous The first compression roller 520, the second compression roller 530, the third compression roller 540, and the fourth compression roller 550 are not only supplied quickly by pulling down, but also to the inlet 105. Adjacent compression rollers (the first compression roller 520, the second compression roller 530, the third compression roller 540, and the fourth compression roller 550) are configured to be smaller than the diameter of the inlet 105, so that the inlet ( The carcasses of highly infectious animals compressed smaller than the diameter of 105) quickly enter the internal tank. For this reason, the highly infectious animal carcasses are not crushed or crushed, and thus the crushed or crushed tissues, blood and pathogens are scattered to become a new source of infection, and it shows a remarkable effect of rapidly supplying highly infectious animal carcasses.

According to the treatment method according to the prior art, in the case of a treatment method that is crushed or pulverized through a crusher or a pulverizer and then supplied to the reactor 100 through the inlet 105, crushing or crushing from animal carcasses that are highly infectious during the crushing or pulverization process. Alternatively, there was a disadvantage in that crushed tissues, blood, and pathogens scattered to become a new source of infection, causing a secondary infection, and a treatment method supplied to the reactor 100 through the inlet 105 without being crushed or crushed. In the case of, there was a disadvantage in that the supply of highly infectious animal carcasses is performed through the inlet 105 by manpower, so that people not only come into contact with the carcasses of highly infectious animals, but also the supply speed is very slow due to the supply by manpower. .

In addition, the "(3) step of heating the inner tank 102 by supplying the saturated steam generated by the high pressure boiler 200 to the inside of the outer tank 101" of the present invention includes a temperature of 230 to 249 °C and a pressure of 2.85. Saturated water vapor generated by the high-pressure high-pressure boiler 200 with a capacity capable of generating ∼4.06 MPa of saturated water is supplied to the external tank 101 for 20 to 30 minutes, so that the temperature of the internal tank 102 is 150-200°C. , As a step of heating the inner tank 102 so that the pressure becomes 0.45 to 1.59 MPa, saturated steam generated by the high pressure high pressure boiler 200 is supplied to the inside of the outer tank 101 for 20 to 30 minutes. The inner tank 102 is heated by water vapor so that the temperature reaches 150~200℃ and the pressure reaches 0.45~1.59 MPa, and then the "(4) hydrothermal carbonization step" to be described later proceeds. And condensed water does not occur in the internal tank 102, so that the "(4) hydrothermal carbonization step" is performed very quickly and efficiently in 20 to 30 minutes.

At this time, the “(3) heating the inner tank 102” is a step of heating the inner tank 102 so that the temperature of the inner tank 102 is 160 to 180°C and the pressure is 0.63 to 1.0 MPa. It is more desirable.

In addition, "(4) of the present invention, while stirring the supplied carcasses of highly infectious animals by the stirrer 103, the saturated steam generated by the high-pressure boiler 200 is heated by the heating device, and the superheated saturated steam is heated in the inner tank ( In the step of hydrothermal carbonization of animal carcasses by direct spraying to 102), the saturated water vapor generated by the high-pressure boiler 200 is stirred by the stirrer 103 while stirring the highly infectious animal carcasses supplied to the inner tank 102. Heated by a heating device, superheated saturated steam with a temperature of 190 to 249 °C and a pressure of 1.28 to 4.06 MPa is directly sprayed to the inner tank 102 to inject the animal carcasses at a temperature of 160 to 240 °C and a pressure of 0.63 to 3.41 MPa. It is a step of hydrothermal carbonization for 30 minutes.

At this time, it is more preferable to hydrothermalize the animal carcasses at a temperature of 180 to 230 °C and a pressure of 1.02 to 2.85 MPa by directly spraying superheated saturated steam with a temperature of 200 to 240 °C and a pressure of 1.59 to 3.41 MPa to the inner tank 102. It is most preferable to hydrothermalize animal carcasses at a temperature of 190 to 220°C and a pressure of 1.28 to 2.37 MPa by directly spraying superheated saturated steam with a temperature of 210 to 230°C and a pressure of 1.95 to 2.85 MPa to the inner tank 102. . These temperatures and pressures are considerably lower than those of the prior art. For this reason, energy is greatly saved, and the processing time is significantly shortened to 20 minutes compared to 1 hour to 1 hour and 30 minutes of the prior art, reducing the processing time by 3 to 4.5 times. In addition to showing a remarkable effect, compared to the prior art, the carbonization degree of the fuel generated by hydrothermal carbonization is greatly improved, and the calorific value reaches 6,100 KJ/kg, which is 133% compared to the heat amount of the fuel generated by the prior art 4,600 KJ/kg. It shows an increased remarkable effect.

In addition, "(5) of the present invention, while cooling the inner tank 102 by supplying cooling water to the outer tank 101, opening the gas discharge valve 109 of the inner tank 102 to discharge exhaust gas, and the compressor 700 The step of cooling the inner tank 102 by supplying compressed air compressed by) to the inner tank 102 is “(a) cooling by cooling water and (b) discharging the gas from the inner tank 102 By opening the valve 109 to discharge exhaust gas and supplying compressed air compressed by the compressor 700 to the inner tank 102 to cool the inner tank 102 at the same time, the cooling is highly This is an efficient process.

The present invention adopts two cooling steps to the internal tank 102 in a high heat and high pressure state in the previous step "(4) hydrothermal carbonization" and the generated fuel (highly infectious animal carcasses after hydrothermal carbonization) As described below, "(6) the step of discharging the exhaust gas after deodorizing the exhaust gas discharged from the cooling step with the deodorization device 300" and "(7) the outlet 106 ) It is possible to quickly perform the step of discharging the hydrothermal and highly infectious animal carcasses to the outlet 106 by opening the opening/closing device, thereby showing a remarkable effect that can greatly shorten the entire treatment process.

That is, the cooling step of the prior art includes only one simple step of cooling the inner tank 102 by supplying cooling water to the outer tank 101, so that the cooling treatment time is 1 hour 30 minutes to 2 hours. In contrast, the cooling step of the present invention is “(a) cooling by cooling water and at the same time (b) opening the gas discharge valve 109 of the inner tank 102 to discharge the exhaust gas, and compressing it by the compressor 700. By simultaneously adopting “two cooling methods” of supplying compressed air to the inner tank 102 to cool the inner tank 102, the cooling treatment time is greatly shortened to 20 to 30 minutes, thereby reducing the cooling treatment time by 3 to 6 times. It shows a remarkable effect of shortening.

Here, in the "(5) cooling step", cooling water is supplied to the outer tank 101 to cool the inner tank 102, while opening the gas discharge valve 109 of the inner tank 102 to discharge exhaust gas. It is more preferable to supply compressed air compressed by the compressor 700 to the inner tank 102 for 20 to 30 minutes to cool the inner tank 102 at a temperature of 80 to 120 °C and a pressure of 0.05 to 0.28 MPa. It is most preferable to cool (102) at a temperature of 80 to 120°C and a pressure of 0.05 to 0.28 MPa.

In addition, the "(6) step of discharging the exhaust gas after deodorizing the exhaust gas discharged in the cooling step by the deodorizing device 300" of the present invention, as described in the previous step, The exhaust gas is discharged by opening the gas discharge valve 109, and the compressed air compressed by the compressor 700 is supplied to the internal tank 102 for 20 to 30 minutes to be discharged, so the conventional technology discharges the exhaust gas according to its own pressure. Compared to that, it shows a remarkable effect in that the time required for discharge is greatly shortened, and the present invention shows a remarkable effect in that the exhaust gas is deodorized by the deodorizing device 300 and then discharged.

Finally, the "(7) step of discharging the hydrothermal and highly infectious animal carcasses to the discharge port 106 by opening the outlet opening/closing device 107" is the same as the known discharge step.

The apparatus for carrying out the method of manufacturing fuel by treating the carcasses of highly infectious animals according to the present invention includes a reactor 100 and a boiler 200 for supplying high-pressure steam to the reactor, the reactor 100, and the reactor 100. A deodorizing device 300 for removing the generated internal gas, a compressor 500 for compressing to smoothly supply the object to be treated, a conveyor 600 for transporting the object to be treated to the compressor 500, and automatically or semi-automatically. It is configured to include a central control panel 400 designed to be operated, a compressor 700 for supplying compressed air into the reactor, and a moving device 800 for moving the device.

In addition, the reactor 100 is equipped with a stirrer 103 that allows the object to be treated to be well mixed, a drive motor 114 that drives the stirrer 103, and a reducer 115 that controls the speed of the drive motor 114. And the agitator 103 is controlled by the central control panel 400, the speed and the direction of rotation.

In addition, the reactor 100 is divided into an inner tank 102 and an outer tank 101, and the outer tank 101 collects water vapor generated from the boiler 200 in order to increase the temperature and pressure above the inner tank 102. A steam supply valve 110 for supplying and shutting off is mounted, and a condensed water discharge valve 111 for automatically discharging the condensed water generated from the external tank 101 is mounted below. In addition, the outer tank 101 is warmed with an insulating material to maintain the temperature. In order to rapidly cool the inner tank 102 after the hydrothermal carbonization process of the object to be processed is completed, a coolant supply valve 110 for supplying coolant to the upper portion of the outer tank 101 and a coolant discharge valve 113 are installed at the lower portion of the outer tank 101. The outer tank 101 is fixed with a tank supporting steel structure 121.

On the other hand, in the reactor 100, the inlet 105 and the inlet opening/closing device 104 for inputting the object to be treated, the outlet 106 and the outlet opening/closing device 107 for discharging the carbonized object, and the supply of steam are controlled. A steam on/off valve 116 that recognizes a temperature, a thermometer 117 that recognizes the pressure, a pressure gauge 120 that recognizes the pressure, a compressed air on/off valve 118 that supplies compressed air, and a safety valve 119 as a safety device are installed. . In addition, a gas discharge device 108 for discharging the gas generated from the inside of the reactor 100 to the outside and a gas discharge valve 109 attached to the gas discharge device 108 are mounted on the upper part of the reactor 100. The exhaust gas discharged through the gas discharge device 108 is transferred to the deodorizing odor 300 and discharged to the outside through a deodorizing process. In addition, at the top of the inlet 105, a compression device 500 for compressing the object to be processed so that the object to be processed can be smoothly supplied to the inlet 105 and a conveyor 600 for supplying the object to be processed to the compression device 500 ) Is connected. In addition, the devices may be mounted on a trailer type truck which is a moving means (800).

The operation of the apparatus for performing the method of manufacturing fuel by processing the carcasses of highly infectious animals according to the present invention will be described below.

As shown in FIG. 1, a reactor outer tank 101 is installed in the reactor 100 for accommodating the object to be treated, and the steam opening/closing valve 110 and the condensate discharge valve 111 for supplying steam and cooling water, and cooling water. It is composed of a cooling water supply valve 112 and a cooling water discharge valve 113 to be supplied, and is configured in a structure capable of receiving steam from the boiler 200 and receiving steam until the internal temperature reaches 150°C or higher. When the outer tank 101 is heated and the temperature of the inner tank 102 is heated to 150° C. or higher, the object to be treated is injected into the inner tank 102 through the inlet 105. In order to facilitate the input of the object to be treated, a movable compression device 500 and a conveyor 600 connected to the compression device 500 are connected to the top of the inlet 105, and the target object is transferred to the reactor 100 using these devices. ). When the object to be treated starts to be transferred to the inner tank 102 of the reactor 100, the agitator 103 installed inside the inner tank 102 is rotated about 20 rpm to 50 rpm so that the input object is well stirred. If the moisture content of the object to be treated is high, the moisture content of the carbide is high, so there may be a problem that a drying process must be installed. Therefore, the moisture content of the object to be treated is controlled by using rice hull or sawdust.

The compressor 500 supports four drive shafts for rotating the compression rollers in the compressor body 510 that supports the drive shaft of the compressor 500 and prevents damage to the compression rollers, and a first compression roller 520 that rotates in combination with each drive shaft. , A second compression roller 530, a third compression roller 540, and a fourth compression roller 550, each consisting of four. Chickens or small objects to be processed may pass through the lower portion of the compressor 500, but large animals such as adult pigs and cows cannot pass through the inlet 105 and must be compressed. Since it is difficult to compress an adult animal at once, the first compression roller 520 has the largest size of the compression roller to sequentially compress the falling object by adjusting the size of the compression roller of the compressor 500. And, the second compression roller 530 is configured smaller than the first compression roller, and the third compression roller 540 is configured smaller than the inlet 105 so that the object to be processed can pass smoothly through the inlet 105. Organize to be able to. Here, the step of the compression roller is illustrated as four stages of the first to fourth compression rollers 520, 530, 540, and 550, and the number of the first to fourth stage compression rollers is composed of four, respectively.

When the input of the object to be treated is completed, the inlet 105 is sealed using the inlet opening/closing device 104 and 3 MPa generated from the boiler 200 The pressure of superheated saturated steam is introduced into the internal tank 102 through the steam on-off valve 116. When the temperature of the internal tank 102 is 190°C or higher and the internal pressure is 1.5 MPa or higher, the steam supply is stopped. Even if the supply of water vapor to the external tank 101 is stopped, the reactor 100 is kept warm with an insulating material, so there is no loss of temperature or pressure, so the temperature and pressure are continuously increased, and even if the supply of saturated water vapor is finally stopped, the temperature is 220. Up to °C, the pressure rises to 2.3 MPa. It takes about 10 minutes to close the steam on-off valve 116 and the temperature to 220° C. or the pressure to 2.3 MPa. The temperature and pressure are automatically controlled by the central control panel 300. When the device is operated under these conditions, the operating cost is reduced and economical operation is possible.

In the process of hydrothermal carbonization of the object to be treated by supplying saturated steam of high temperature and high pressure to the inner tank 102, stirring the inner tank 102 with a stirrer 103 is continued so that the object to be treated is sufficiently homogenized and the reaction proceeds with a stirrer. Continue rotating while adjusting (103) in the forward and reverse directions. The object to be treated is sufficiently carbonized by superheated saturated steam within 20 minutes after the temperature and pressure reach the set value. Since superheated saturated steam at high temperature and high pressure has the property of hydrolyzing organic matter, the hydrothermal carbonization process alone prevents the removal of harmful gases such as ammonia and sulfur dioxide, as well as the generation of harmful gases such as dioxin. When hydrothermal carbonization is completed, the cooling water supply valve 112 is opened to supply cooling water to the external tank 101 to cool it, and at the same time, the gas discharge valve 109 of the internal tank 102 is opened to discharge exhaust gas. By generating compressed air and supplying about 0.4 MPa of compressed air to the inner tank 102 through the air inlet, the temperature of the inner tank 102 drops more quickly, so that the temperature of the inner tank 102 is about 120°C and pressure. It is cooled until it becomes about 0.4 MPa. When cooled to 120℃ or less, condensed water is generated in the internal tank 102, and the moisture content of the hydrothermal carbide increases, causing the hassle of having to go through a drying process after discharging the object to be treated. If the pressure is too low, the exhaust gas is deodorized. It cannot be released into the atmosphere by passing through. When cooling is completed, the gas in the internal tank 102 is opened to the gas discharge valve 109 attached to the gas discharge device 108 to transfer the gas to the deodorization device 300 through a pipe.

The deodorizing device 300 is composed of two tanks each containing an alkali component and an acid component. As the neutralizing agent for the deodorizing gas, various organic acids such as citric acid and strong acids such as sulfuric acid, phosphoric acid, hydrochloric acid, etc. can be used as the acidic component, and strong bases such as caustic soda and caustic fish, soda, and quicklime can be used as the basic component. The transferred volatile gas is completely deodorized by the deodorizing device 300, which is mainly composed of two kinds of neutralizing substances. The gas component deodorized while passing through the deodorization device 300 is discharged to the atmosphere.

When the exhaust gas is completely discharged to the atmosphere through the deodorization device 300 and the temperature is 80°C or less, the agitator 103 is rotated in the forward direction where it can be discharged, and the discharge port 106 is opened using the discharge port opening/closing device 107. The hydrothermal carbonized object to be treated is discharged from the inner tank 102. The discharged carbide is placed in a suitable container.

A device for manufacturing fuel by processing the movable carcasses of highly infectious animals that perform the above operation is mounted on a truck equipped with a trailer or the like for rapid movement. The method of manufacturing fuel by processing the carcasses of highly infectious animals according to the present invention has a very short processing time from input to discharge of about 1 hour, and has excellent processing capacity compared to conventional devices that take 2 hours 30 minutes to 4 hours. Can be seen.

Infectious disease-infected animals fueling method and mobile fuel manufacturing device that perform this operation not only have the advantage of being able to quickly move to the area where bird flu or foot-and-mouth disease has occurred and fuel the carcasses of highly infectious animals in a short time, but also when infectious diseases do not occur. It can also be used to treat wastes such as pathogenic waste, waste plastic, and household waste.

If the method of manufacturing fuel by treating highly infectious animal carcasses according to the present invention can be used to treat wastes that are difficult to recycle into fuel, it can greatly contribute to the improvement of the waste sorting method.

In addition, the method of manufacturing fuel by treating the carcasses of highly infectious animals according to the present invention relies on landfill or incineration because livestock waste such as food waste, sewage sludge, and livestock, organic waste such as waste wood and waste paper can be carbonized and converted into fuel. It can be an alternative to the way there is.
