Description

Technical Field

[0001] The invention relates to a device for preparing carbon fertilizer by treating domestic garbage, in particular to a device for preparing carbon fertilizer by cracking garbage organic matter through a rotating superconducting heat transfer tube with low energy consumption, high efficiency, no pollution to the environment and no generation of toxic substances. Background Art

[0002] With the progress of human civilization and the growth of population, the production of urban and rural domestic garbage is increasing, the composition of garbage is becoming more and more complex, and the harmful components are increasing. The traditional landfill method will be phased out due to the waste of land, damage to groundwater sources and environmental safety. At present, the incinerators used in various places to burn garbage have caused serious pollution to the environment, which has led to public opposition. The burning of garbage emits a large amount of smoke, harmful particulate matter, acidic gases, unburned waste, heavy metals and a large amount of carbon dioxide, and produces more than 40 kinds of carcinogens and dioxins. At the same time, the burning turns the organic matter of the garbage into ashes, causing a waste of resources. At present, the 700 large-scale garbage incineration facilities in China have invested a lot of manpower, material resources, financial resources and land. The collection, transportation, rough treatment, compression and final delivery of garbage to the garbage incineration plant for incineration in communities, towns, rural areas, factories, hospitals, railways, scenic spots, large farms and other units account for more than half of the garbage disposal costs. Judging from the development trends at home and abroad, incineration of garbage is no longer the final solution for garbage disposal. Solving the problem of reducing, recycling and harmless treatment of domestic garbage from the source has become the focus of governments at all levels. The daily output of urban domestic garbage is about 180 million tons, the transportation volume is 140 million tons, and the treatment rate is 80%. The main garbage disposal methods are landfill or incineration; the daily output of rural domestic garbage is about 190 million tons, and the treatment rate is less than 10%. More than 90% of rural domestic garbage is mainly treated by temporary stacking, incineration and random dumping. This primitive and rough garbage disposal method has greatly affected the rural living environment, threatened people's health, and restricted overall economic development. Summary of the invention

[0003] The domestic garbage, used clothing, plastics, furniture, animal feces, crop straw, agricultural film, branches, weeds and other organic matter generated by scattered units such as communities, rural areas, hospitals, farms, schools, factories, railways, troops, schools, scenic spots, etc. are cracked into carbon fertilizer and other useful products using a rotating superconducting heat transfer tube cracking device. Experiments have proved that this is one of the excellent solutions to achieve garbage reduction, harmlessness, and turning waste into treasure, save manpower, material resources, financial resources, and land, improve the rural living environment, and prevent the emission of harmful substances.

[0004] The device for preparing carbon fertilizer by cracking garbage organic matter with rotating superconducting heat transfer tubes is a highly efficient, pollution-free and harmless device for preparing carbon fertilizer from garbage organic matter on site. It is a new type of device for preparing carbon fertilizer from garbage organic matter designed by utilizing the principles of rapid heat collection, heat transfer and heat dissipation of efficient rotating superconducting heat transfer tubes, the heat shielding characteristics of rotating superconducting heat transfer tubes, the rapid heat equalization characteristics, and the principle of rapid reflux of high-temperature metal working fluids under the combined force of gravity and centrifugal force. The carbon fertilizer preparation device places solid garbage and organic matter in a sealed temperature equalization cracking device, and under certain temperature, pressure and catalyst conditions, causes a series of reactions between the organic matter in the garbage and the gasifying agent, rapidly breaking up and volatilizing the high molecular hydrocarbons. The volatile gases include CO, H2, CH, and CNH m The solid product is organic carbon fertilizer. The combustible mixed gas is recovered as a heat source for continuously cracking waste organic matter to produce carbon fertilizer.

[0005] The device for preparing carbon fertilizer by cracking garbage organic matter with a rotating superconducting heat transfer tube comprises a cracking body shell, a high-efficiency heat-absorbing heat-transfer rotating superconducting heat transfer tube installed in the cracking body shell and located in the center of a garbage cracking tank for transmitting cracking heat to the garbage cracking tank, a ring heater installed in a heating chamber at the bottom of the rotating superconducting heat transfer tube for supplying heat to the rotating superconducting heat transfer tube, a power device installed in a power chamber at the bottom of the rotating superconducting heat transfer tube for driving the rotating superconducting heat transfer tube to rotate, a cracking chamber installed around the heat-absorbing section at the bottom of the rotating superconducting heat transfer tube for secondary cracking of combustible mixed gas, a feeding machine for feeding materials to the garbage cracking tank, a garbage organic matter crusher for providing crushed materials to the feeding machine, a conveyor belt for conveying carbon fertilizer prepared by the device for preparing carbon fertilizer by cracking garbage organic matter with a rotating superconducting heat transfer tube, a gas-liquid separator for processing and recovering the combustible mixed gas prepared by the device for preparing carbon fertilizer by cracking garbage organic matter with a rotating superconducting heat transfer tube as a heat source for continuous cracking of garbage organic matter, a purifier, a centrifuge, a water seal tank, and a burner for starting the garbage cracking tank. The garbage cracking tank is a cylindrical sealed container with a large upper part and a small lower part. The upper part is equipped with a tank cover with the same diameter as its upper edge. A high-temperature resistant sealing strip is installed between the tank cover and the upper edge of the garbage cracking tank. One side of the tank cover is a feed port, and a feed port cover is installed on the feed port. The feed port cover automatically closes after the loader loads the garbage. A catalyst tank is installed on the top of the tank cover, and the catalyst tank is connected to the garbage cracking tank through a catalyst valve. A number of heat-absorbing fins are installed around the outer periphery of the tank wall of the garbage cracking tank, which can transfer the heat of the hot flue outside the cracking tank to the garbage in the garbage cracking tank through a number of heat-absorbing fins and the tank wall. The lower side of the garbage cracking tank is a carbon fertilizer discharge pipe, and the carbon fertilizer discharge pipe mouth extends into the water of the water seal box. The circular hole in the lower center of the garbage cracking tank is inlaid with a high-temperature resistant bearing, and the rotating superconducting heat transfer pipe is installed in the high-temperature resistant bearing. The upper part is the heat dissipation section (condensation end) of the rotating superconducting heat transfer pipe, and the lower part is the heat absorption section (evaporation end) of the rotating superconducting heat transfer pipe. The heat dissipation section of the rotating superconducting heat transfer tube is evenly equipped with a puckered plate, and the heat absorption section is evenly equipped with a plum blossom-shaped heat absorption plate. The lower side of the heat absorption section is fastened to the rotating column in the center of the heat insulation board. The rotating column is installed in the power room, and a chain plate is installed on the column. The side of the rotating column is a power device motor, a reducer, and a chain. The rotation of the motor drives the rotating column, the rotating superconducting heat transfer tube, and the puck to rotate through the reducer, the chain, and the chain plate, which can improve the heat transfer performance of the rotating superconducting heat transfer tube, so that the garbage organic matter in the garbage cracking tank is heated evenly, the garbage organic matter cracking efficiency is high, the gas production is large, and the carbon content of the carbon fertilizer is high. The combustible mixed gas cracked by the garbage in the garbage cracking tank enters the annular heater in the heating chamber through the gas transmission pipe, the cracking chamber, the output pipeline, the gas-liquid separator, the purifier, the centrifuge, and the water seal tank to continuously provide heat for the garbage cracking.

[0006] The garbage cracking tank for garbage cracking is a cylindrical sealed container, which closes the tank cover, the feed inlet sealing cover, the catalyst valve and the output pipeline valve. The leakage rate of the garbage cracking tank is less than 5X10 -2Pa·L / s, the pyrolysis tank is in an anaerobic or anaerobic state in working state. The garbage will not produce harmful gases such as dioxins when it is pyrolyzed under anaerobic or anaerobic conditions, and the carbon generated by the pyrolysis of the garbage is of high quality.

[0007] The rotating superconducting heat transfer tube is a vertical cylindrical superconducting rotating body that rotates 360 degrees around the axis of the garbage cracking tank. The rotating superconducting heat transfer tube is filled with a metal superconducting medium, which accounts for 20% to 30% of its total space volume. The metal superconducting medium is an activated liquid sodium-potassium alloy with an operating temperature of 500°C to 800°C, and the mass ratio of the sodium-potassium alloy is sodium:potassium=1:3. The internal negative pressure of the rotating superconducting heat transfer tube is 1.3X10 -3 Pa, the space is in a positive pressure state during operation. After the lower heat absorption section (evaporation end) of the rotating superconducting heat transfer tube is heated by the annular heater, the internal metal superconducting medium changes phase and gasifies. The heat dissipation section of the rotating superconducting heat transfer tube transfers the latent heat of phase change through the plate on the heat dissipation section of the rotating superconducting heat transfer tube, and quickly and evenly transfers the heat to the garbage in the closed garbage cracking tank, providing heat energy for the garbage to be cracked and gasified to make carbon. In order to increase the temperature in the garbage cracking tank, the total heat exchange area of ​​the plum blossom-shaped heat absorption plate in the heat absorption section (evaporation end) is ≧ the plate area on the heat dissipation section of the rotating superconducting heat transfer tube. After the rotating superconducting heat transfer tube transfers the latent heat of phase change to the garbage in the closed garbage cracking tank, the high-temperature metal medium quickly returns to the heat absorption section (evaporation end) under the combined force of gravity and rotating centrifugal force, and continues the above-mentioned heat absorption (evaporation) heat transfer and heat dissipation (condensation) process, repeatedly sending the heat generated by the heater to the garbage cracking tank, and repeatedly completing the garbage gasification and carbon fertilizer process.

[0008] The shell of the cracking body and the tank cover are both equipped with an insulation layer, which is an inorganic thermal insulation material with a thermal conductivity of less than 0.05W / (mK) and a heat-resistant temperature greater than 1000°C, such as alumina polycrystalline fiber wool, rare earth insulation mud, ceramic fiber insulation wool, or asbestos insulation layer, graphite insulation layer, etc. The thickness of the insulation layer is 15cm to 20cm, which can prevent the temperature of the cracking body shell from spreading outward.

[0009] The heating chamber is separated from the power chamber by an insulation board, and the annular heater is placed on the insulation board. The annular heater is connected to the water seal tank through a pipeline, an air supply valve, and a flame retardant. The heat generated by the annular heater forms a thermal field that surrounds the plum blossom-shaped heat absorption plate and the cracking cavity of the heat absorption section of the rotating superconducting heat transfer tube. The waste heat is absorbed by a number of heat absorption fins and the tank wall around the outer side of the garbage cracking tank through the hot flue and is conducted to the garbage in the garbage cracking tank. When the heater is working, the temperature of the heating chamber reaches 1000°C, and the outer shell of the cracking body around the heating chamber is filled with refractory bricks. Good heat preservation and waste heat utilization have high carbon production efficiency, and the device can achieve zero emissions.

[0010] The hot flue formed between the shell of the cracking body and the outer side of the wall of the garbage cracking tank is separated from the space of the garbage cracking tank. A combustible mixed gas delivery pipe is installed in the hot flue. The upper end of the mixed gas delivery pipe is communicated with the gas outlet of the garbage cracking tank, and the lower end is communicated with the cracking chamber. The combustible mixed gas enters the cracking chamber and is subjected to the high temperature of the heating chamber. The combustible mixed gas is secondary cracked in the cracking chamber, and the cracking oil in the combustible mixed gas can be converted into combustible gas, thereby increasing the thermal energy of the garbage cracking gas of the device.

[0011] The catalyst tank installed on the top of the tank cover contains a liquid catalyst. The liquid catalyst is a mixture of 95% water, 3% dolomite and 2% Fe2O3 powder. When the garbage cracking tank is loaded, the catalyst valve is adjusted, and the liquid catalyst is mixed in the garbage with the rotation of the rotating superconducting heat transfer tube plate. The water in the liquid catalyst is to meet the humidity requirements of the garbage in cracking and gasification. Experiments show that when the temperature of the garbage cracking reaction zone in the garbage cracking tank is 600℃~800℃, water vapor as a gasifying agent can accelerate the reaction rate of the garbage, and the conversion rate of garbage gas production and the escape rate of carbon fertilizer are significantly improved. The addition of water vapor in the high-temperature garbage cracking tank greatly increases the gas production of the material as the temperature increases. Because the reaction temperature in the furnace increases, the temperature rise rate of the garbage is accelerated, and the garbage that reacts and releases gas in the garbage layer increases, so the instantaneous yield of the gas increases and the overflow of carbon fertilizer impurities decreases. With the addition of water vapor, part of the gas released by the garbage reaction reacts with water vapor first, and further decomposes to produce other small molecular gases. Some small molecular gases will continue to react with water vapor. Such a reaction process prolongs the duration of the entire reaction and increases the total gas production. Under a water vapor atmosphere of 800℃, the total gas production rate of urban domestic garbage, kitchen waste and paper scraps can be close to 950L / kg at most, and the calorific value is increased by 40%. This is because as the temperature rises, the secondary cracking of tar reacts with water vapor to reform, increasing the content of combustible gases such as CO and H2. In particular, in a water vapor atmosphere of 800℃, in addition to the reforming reaction of the secondary cracking of kitchen waste with water to increase the content of combustible gases, 800℃ is also conducive to the reaction of residual carbon in kitchen waste with water vapor to produce water gas, thereby increasing the purity of carbon fertilizer. Dolomite in the liquid catalyst is a catalyst. Experiments show that when dolomite is added to garbage, when the temperature of the garbage cracking reaction zone in the garbage cracking tank is 600℃~800℃, dolomite as a catalyst significantly increases the content of combustible gas H2 and reduces the tar content, reducing carbon accumulation on the surface of the equipment. Adding Fe2O3 powder to dolomite makes dolomite modified dolomite, and the modified dolomite improves the activity of the dolomite catalyst. Experiments show that at 750℃, under the catalytic conditions of modified dolomite, the volume fraction of H2 is 45.77%±0.23%, and the temperature required for gasification is reduced by 100℃ compared with the hydrogen enrichment effect under the conditions of no catalysis and dolomite catalysis. Modified dolomite not only promotes the scission of carbon-carbon long chains on the hydrocarbon end chains, generates hydrogen free radicals, and then forms H2, but also promotes aromatic ring opening reactions, decarboxylation and dehydroxylation reactions, making it easier for the tar after garbage cracking to enter the cracking chamber and be converted into small molecule gas.

[0012] The working process of the rotating superconducting heat transfer tube cracking garbage organic matter to produce carbon fertilizer is: open the feeder to feed the garbage crushed by the crusher into the garbage cracking tank, add the catalyst, automatically close the feed port cover and the catalyst valve, open the air supply valve, ignite the annular heater, and the heat generated by the work forms a thermal field that surrounds the plum blossom-shaped heat absorption plate and cracking tube of the rotating superconducting heat transfer tube heat absorption section. The rotating superconducting heat transfer tube quickly transfers the heat to the turning garbage through the dial plate. The residual heat from heating is absorbed by the heat absorption fins and the tank wall outside the garbage cracking tank through the hot flue and transferred to the garbage in the garbage cracking tank. The garbage is heated and cracked under the action of the catalyst. The generated mixed gas enters the cracking chamber through the gas outlet and gas delivery pipe of the garbage cracking tank and is secondary cracked under the action of high temperature in the heating chamber. The combustible gas from the secondary cracking enters the gas-liquid separator, purifier, centrifuge, water seal tank through the output pipeline and then enters the annular heater through the flame retardant and gas supply valve, providing a continuous working heat source for the garbage cracking tank to crack the garbage organic matter to produce carbon fertilizer. The rotating superconducting heat transfer tube rotates under the drive of the power device to discharge the carbon fertilizer obtained after the garbage cracking from the carbon discharge pipe to the conveyor belt of the water seal box, and then the conveyor belt is sent to the carbon fertilizer collection tank.

[0013] The rotating superconducting heat transfer tube cracking garbage organic matter to produce carbon fertilizer device can be used to treat the domestic garbage, waste clothing, plastics, furniture, animal feces, crop straw, agricultural film, branches, weeds and other organic matter generated by scattered units such as communities, rural areas, fields, hospitals, farms, schools, factories, railways, troops, schools, scenic spots, etc., and can be harmlessly processed on site to produce fertilizers. While achieving garbage reduction and harmlessness without leaving home, it can fully utilize waste, save manpower, material resources, financial resources and land, and improve the living environment. There is no smoke, no fly ash, no wastewater, no dioxin, and no carbon dioxide emissions during the garbage cracking process. The garbage is cracked thoroughly, the gas is self-sufficient, and the carbon fertilizer produced is of high quality. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The technical solutions in the embodiments of the present invention will be described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0019] See also Figure 1The embodiment of the present invention provides a device for preparing carbon fertilizer by cracking garbage organic matter with a rotating superconducting heat transfer tube, comprising: a cracking body shell 1, a garbage cracking tank 2 installed in the center of the cracking body shell 1, a high-efficiency heat-absorbing heat-transfer rotating superconducting heat transfer tube 3 for transmitting cracking heat, a heating chamber 4 installed at the bottom of the rotating superconducting heat transfer tube 3, a ring heater 5 for supplying heat to the rotating superconducting heat transfer tube 3, a power chamber 6 installed at the bottom of the rotating superconducting heat transfer tube 3, a power device 7 for driving the rotating superconducting heat transfer tube 3 to rotate, a heat-absorbing section 8 installed at the bottom of the rotating superconducting heat transfer tube 3, and a surrounding combustible mixed gas.

The garbage cracking tank 2 is a cylindrical sealed container with a large upper part and a small lower part, and a tank cover 19 with the same diameter as its upper edge is installed on its upper part, and a high-temperature resistant sealing strip 20 is installed between the tank cover 19 and the upper edge of the garbage cracking tank 2, and a feed port 21 is provided on one side of the tank cover 19, and a feed port cover 22 is installed on the feed port 21, and the feed port cover 22 is automatically closed after the feeder 10 has finished feeding the garbage. A catalyst tank 23 is installed on the top of the tank cover 19, and the catalyst tank 23 is connected to the garbage cracking tank 2 through a catalyst valve 24. A plurality of heat-absorbing fins 25 are installed on the outer periphery of the tank wall 27 of the garbage cracking tank, which can transfer the heat of the hot flue 26 outside the garbage cracking tank 2 to the garbage 28 in the garbage cracking tank through the plurality of heat-absorbing fins 25 and the tank wall 27. A carbon fertilizer discharge pipe 29 is installed on the lower side of the garbage cracking tank 2, and the carbon fertilizer discharge pipe mouth extends into the water of the water seal box 30. A high-temperature resistant bearing 31 is embedded in the circular hole at the center of the lower part of the garbage cracking tank 2. The rotating superconducting heat transfer pipe 3 is installed in the high-temperature resistant bearing 31, and the upper part is the heat dissipation section (condensation end) 32 of the rotating superconducting heat transfer pipe 3, and the lower part is the heat absorption section (evaporation end) 8 of the rotating superconducting heat transfer pipe. A plurality of paddles 33 are evenly mounted on the heat dissipation section (condensation end) 32 of the rotating superconducting heat transfer tube, and a plum blossom-shaped heat absorption plate 34 is evenly mounted on the heat absorption section (evaporation end) 8. The lower side of the heat absorption section (evaporation end) 8 is fastened to a rotating column 36 at the center of the heat insulation plate 35. The rotating column 36 is mounted in the power chamber 6. A chain plate 37 is mounted on the column. A power device motor 38, a reducer 39, and a chain 40 are mounted on the side of the rotating column 36. The rotation of the motor 38 drives the rotating column 36, the rotating superconducting heat transfer tube 3, and the paddles 33 to rotate through the reducer 39, the chain 40, and the chain plate 37, thereby improving the heat transfer performance of the rotating superconducting heat transfer tube 3, making the organic matter in the garbage 28 in the garbage cracking tank 2 evenly heated, improving the cracking efficiency of the garbage organic matter, increasing the gas production, and increasing the carbon content of the carbon fertilizer 12.The combustible mixed gas cracked by the garbage in the garbage cracking tank 2 enters the annular heater 5 of the heating chamber 4 through the gas delivery pipe 41, the cracking chamber 9, the output pipeline 43, the gas-liquid separator 14, the purifier 15, the centrifuge 16, and the water seal tank 17, continuously providing heat for the garbage cracking.

[0020] The garbage cracking tank 2 for garbage cracking is a cylindrical sealed container. The tank cover 19, the feed inlet cover 22 on the feed inlet, the catalyst valve 24 and the pipeline valve 42 of the output pipeline 43 are closed. The leakage rate of the garbage cracking tank 3 is less than 5X10 -2 Pa·L / s, the working state of the cracking cracking tank 3 is anaerobic or anaerobic. The garbage will not produce harmful gases such as dioxins when cracked under anaerobic or anaerobic conditions, and the carbon cracked by the garbage is of high quality.

[0021] The rotating superconducting heat transfer tube 3 is a vertical cylindrical superconducting rotating body that rotates 360 degrees around the axis of the garbage cracking tank 2. The rotating superconducting heat transfer tube 3 is filled with a metal superconducting medium 44, which occupies 20% to 30% of its total space volume. The metal superconducting medium 44 is an activated liquid sodium-potassium alloy with an operating temperature of 500°C to 800°C, and the mass ratio of the sodium-potassium alloy is sodium:potassium=1:3. The negative pressure of the internal space of the rotating superconducting heat transfer tube 3 when it is static is 1.3X10 -3 Pa, the space is in a positive pressure state during operation. After the lower heat absorbing section (evaporation end) 8 of the rotating superconducting heat transfer tube 3 is heated by the annular heater, the internal metal superconducting working medium 44 undergoes phase change and gasifies. The heat dissipation section (condensation end) 32 of the rotating superconducting heat transfer tube 3 transfers the latent heat of phase change through the plate 33 on the heat dissipation section of the rotating superconducting heat transfer tube, and quickly and evenly conducts the heat to the garbage 28 in the closed garbage cracking tank 2, providing heat energy for the cracking and gasification of the garbage 28. In order to increase the temperature in the garbage cracking tank 2, the total heat exchange area of ​​the plum blossom-shaped heat absorbing plate 34 of the heat absorbing section (evaporation end) 8 is ≧ the total area of ​​the plate 33 on the heat dissipation section (condensation end) 32 of the rotating superconducting heat transfer tube. After the rotating superconducting heat transfer tube 3 transfers the latent heat of phase change to the garbage 28 in the closed garbage cracking tank 2, the high-temperature metal superconducting medium 44 quickly returns to the heat absorption section (evaporation end) 8 under the combined action of gravity and rotating centrifugal force, and continues the above-mentioned heat absorption (evaporation), heat transfer, and heat dissipation (condensation) processes, and repeatedly sends the heat generated by the annular heater 5 to the garbage cracking tank 2, repeatedly completing the garbage gasification and carbon fertilizer production process.

[0022] The cracking body shell 1 and the tank cover 19 are both equipped with an insulation layer, which is an inorganic thermal insulation material with a thermal conductivity of less than 0.05W / (mK) and a heat-resistant temperature greater than 1000°C, such as alumina polycrystalline fiber wool, rare earth insulation mud, ceramic fiber insulation wool, or asbestos insulation layer, graphite insulation layer, etc. The thickness of the insulation layer is 15cm to 20cm, which can prevent the temperature inside the cracking body shell 1 from diffusing outward.

[0023] The heating chamber 4 is separated from the power chamber 6 by a heat insulation board 35, and the annular heater 5 is placed on the heat insulation board 35. The annular heater 5 is connected to the water seal tank 17 through a pipeline 46, an air supply valve 47, and a flame retardant 48. The heat generated by the working of the annular heater 5 forms a thermal field that surrounds the plum blossom-shaped heat absorption plate 34 and the cracking chamber 9 of the heat absorption section of the rotating superconducting heat transfer tube. The waste heat is absorbed by a number of heat absorption fins 25 and the tank wall 27 on the outer periphery of the garbage cracking tank wall through the hot flue 26 and is conducted to the garbage 28 in the garbage cracking tank 2. When the annular heater 5 is working, the temperature of the heating chamber 4 reaches 1000°C, and the cracking body shell 1 around the heating chamber 4 is equipped with refractory bricks 49. Good heat preservation and waste heat utilization have high efficiency in carbon and gas production, and the device can achieve zero emissions.

[0024] The hot flue 26 formed between the cracking body shell 1 and the outer side of the garbage cracking tank wall 27 is separated from the space inside the garbage cracking tank 2. A combustible mixed gas delivery pipe 41 is installed in the hot flue 26. The upper end of the mixed gas delivery pipe 41 is communicated with the gas outlet 51 of the garbage cracking tank 2, and the lower end is communicated with the cracking chamber 9. The combustible mixed gas enters the cracking chamber 9 and is subjected to the high temperature of the heating chamber. The combustible mixed gas is secondary cracked in the cracking chamber 9, and the cracking oil in the combustible mixed gas can be converted into combustible gas, thereby increasing the thermal energy of the garbage cracking gas of the device.

[0025] The catalyst tank 23 installed on the top of the tank cover 19 contains a liquid catalyst, which is a mixture of 95% water, 3% dolomite and 2% Fe2O3 powder. When the garbage cracking tank 2 is loaded, the catalyst valve 24 is adjusted, and the liquid catalyst is mixed in the garbage 28 with the rotation of the rotating superconducting heat transfer tube plate 33. The water in the liquid catalyst is to meet the humidity requirements of the garbage in cracking and gasification. Experiments show that when the temperature of the garbage cracking reaction zone in the garbage cracking tank 2 is 600℃~800℃, water vapor as a gasifying agent can accelerate the reaction rate of the garbage, and the conversion rate of garbage gas production and the escape rate of carbon fertilizer are significantly improved. The addition of water vapor in the high-temperature garbage cracking tank greatly increases the gas production of the material as the temperature increases. Because the reaction temperature in the furnace increases, the garbage temperature rises faster, and the garbage that reacts and releases gas in the garbage layer increases, so that the instantaneous yield of gas increases and the overflow of carbon fertilizer impurities decreases. With the addition of water vapor, part of the gas released by the garbage reaction reacts with water vapor first, and further decomposes to produce other small molecular gases. Some small molecular gases will continue to react with water vapor. Such a reaction process prolongs the duration of the entire reaction and increases the total gas production. Under a water vapor atmosphere of 800℃, the total gas production rate of urban domestic garbage, kitchen waste and paper scraps can be close to 950L / kg at most, and the calorific value is increased by 40%. This is because as the temperature rises, the secondary cracking of tar reacts with water vapor to reform, increasing the content of combustible gases such as CO and H2. In particular, in a water vapor atmosphere of 800℃, in addition to the reforming reaction of the secondary cracking of kitchen waste with water to increase the content of combustible gases, 800℃ is also conducive to the reaction of residual carbon in kitchen waste with water vapor to produce water gas, thereby increasing the purity of carbon fertilizer. The dolomite in the liquid catalyst is a catalyst. Experiments show that when dolomite is added to the garbage, when the temperature of the garbage cracking reaction zone in the garbage cracking tank 2 is 600℃~800℃, dolomite as a catalyst significantly increases the content of combustible gas H2 and reduces the tar content, reducing carbon accumulation on the surface of the equipment. Adding Fe2O3 powder to dolomite makes the dolomite modified dolomite, and the modified dolomite improves the activity of the dolomite catalyst. Experiments show that at 750℃, under the catalytic conditions of modified dolomite, the volume fraction of H2 is 45.77%±0.23%, and the temperature required for gasification is reduced by 100℃ compared with the hydrogen enrichment effect under the conditions of no catalysis and dolomite catalysis. Modified dolomite not only promotes the long carbon-carbon chain on the hydrocarbon end chain to break, generate hydrogen free radicals, and then form H2, but also promotes the aromatic ring opening reaction, decarboxylation and dehydroxylation reactions, so that the tar after garbage cracking enters the cracking chamber 9 and is more easily converted into small molecule gas.

[0026] The working process of the device for preparing carbon fertilizer by cracking garbage organic matter with a rotating superconducting heat transfer tube is as follows: the feeder 10 is turned on to feed the garbage 28 crushed by the crusher 11 into the garbage cracking tank 2, the catalyst valve 24 is adjusted to add liquid catalyst, the feed port cover 22 and the catalyst valve 24 are automatically closed, the air supply valve 47 is opened, the annular heater 5 is ignited, and the heat generated by the work forms a thermal field that surrounds the plum blossom-shaped heat absorbing plate 34 and the cracking cavity of the heat absorbing section of the rotating superconducting heat transfer tube, and the rotating superconducting heat transfer tube 3 quickly transfers the heat to the turned garbage 28 through the paddle plate 33. The residual heat from heating is absorbed by a plurality of heat absorbing fins 25 and the tank wall 28 on the outer periphery of the garbage cracking tank wall through the hot flue 26 and transferred to the garbage 28 in the garbage cracking tank 2. The garbage is heated and cracked under the action of liquid catalyst. The generated mixed gas enters the cracking chamber 9 through the gas outlet 51 of the garbage cracking tank and the mixed gas delivery pipe 41, and is secondary cracked under the action of high temperature in the heating chamber. The combustible gas of secondary cracking enters the gas-liquid separator 14, the purifier 15, the centrifuge 16, the water seal tank 17 through the output pipe 43, and then enters the annular heater 5 through the flame retardant 48 and the gas supply valve 47, so as to provide a continuous working heat source for the production of carbon fertilizer from the garbage organic matter in the garbage cracking tank 2. The rotating superconducting heat transfer tube 3 rotates under the drive of the power device 7, and the plate 33 rotates to discharge the carbon fertilizer 12 obtained after the garbage is cracked from the carbon discharge pipe 29 to the conveyor belt 13 of the water seal box 30, and then the conveyor belt 13 sends it to the carbon fertilizer collecting tank 50.
