Description

Technical Field

[0001] This invention relates to the field of biomass energy technology, specifically to an oil-filled mixed biomass storage carbon heating furnace. Background Technology

[0002] With increasing energy demand and stricter environmental protection requirements, biomass energy, as a renewable and clean energy source, has received widespread attention. Biomass pyrolysis carbonization technology is the process of heating and decomposing biomass raw materials under anaerobic or oxygen-deficient conditions to produce biochar, bio-oil, and pyrolysis gas.

[0003] Existing biomass pyrolysis technology suffers from high energy consumption, direct emission of bio-oil and pyrolysis gas, resulting in environmental pollution. During pyrolysis, a large amount of heat is lost, and the biomass material used for pre-drying before pyrolysis is not effectively recovered, leading to increased energy consumption in subsequent pyrolysis. Furthermore, the heat released by cooling the biochar produced during pyrolysis is not utilized properly and is usually directly dissipated into the environment, failing to provide hot water for daily life or industrial production, which runs counter to the current development concept of energy conservation and environmental protection. Summary of the Invention

[0004] The purpose of this invention is to provide an oil-filled mixed biomass storage carbon heating furnace, which features efficient energy recovery and utilization during the pyrolysis process, thereby improving the utilization efficiency of biomass energy.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an oil-filled mixed biomass storage carbon heating furnace, comprising a support rod fixedly installed at the bottom of a feeding box and a support ladder fixedly installed on the right side of the heating furnace; a storage hopper fixedly installed at the top of the feeding box; a feed nozzle fixedly installed at the bottom of the feeding box; a cooling furnace fixedly installed at the bottom of the heating furnace; a pyrolysis furnace fixedly installed inside the heating furnace; an annular combustion seat fixedly installed between the heating furnace and the pyrolysis furnace; the feed nozzle penetrating the top of the heating furnace and communicating with the pyrolysis furnace; and a drying hood fixedly installed at the top of the feeding box.

[0006] By adopting the above technical solution, the annular combustion seat is located between the heating furnace and the pyrolysis furnace, ensuring the continuity of the temperature inside the pyrolysis furnace. The annular combustion seat is made of high-temperature resistant and corrosion-resistant materials, which can adapt to the high temperature and corrosive environment generated during combustion. The annular combustion seat provides the heat required for the pyrolysis reaction, and the pyrolysis furnace provides an oxygen-deficient or oxygen-free pyrolysis environment for the biomass raw materials. Under this environment, the organic components in the biomass raw materials can avoid being oxidized by oxygen, but instead decompose into small-molecule gaseous, liquid and solid products, such as biogas, biooil and biochar, through the pyrolysis reaction.

[0007] In a preferred embodiment of the oil-filled mixed biomass storage carbon heating furnace of the present invention, a speed-regulating motor is fixedly installed at the front of the feeding box, an air pump is fixedly installed at the rear of the feeding box, a feeding belt is installed at the output end of the speed-regulating motor, and multiple guide rollers are provided on the inner side of the feeding box.

[0008] In a preferred embodiment of the oil-filled mixed biomass storage carbon heating furnace of the present invention, a return gas pipe is fixedly installed at one end of the spiral tube, one end of the return gas pipe is fixedly connected to the feeding box, and an outlet gas pipe is fixedly installed at the other end of the spiral tube.

[0009] In a preferred embodiment of the oil-filled mixed biomass storage carbon heating furnace of the present invention, one end of the gas outlet pipe is fixedly installed with the input end of the gas pump, and the output end of the gas pump is connected to the air drying hood.

[0010] By adopting the above technical solution, the drying hood can dry the biomass raw materials that fall onto the feeding belt. After drying, the moisture content of the raw materials is reduced, so less energy is needed during the subsequent pyrolysis. The air pump blows the hot air from the spiral tube into the drying hood through the air outlet pipe. The drying hood dries the raw materials by blowing hot air. After drying, the air is sucked away from the air return pipe and then heated again. In this way, the hot air can be recycled and used to pre-dry the biomass raw materials.

[0011] In a preferred embodiment of the oil-filled mixed biomass storage carbon heating furnace of the present invention, a spiral conical tube is fixedly installed on the inner side of the cooling furnace, an inlet head is fixedly installed at one end of the spiral conical tube, and an outlet head is fixedly installed at the other end of the spiral conical tube.

[0012] In a preferred embodiment of the oil-filled mixed biomass storage carbon heating furnace of the present invention, a filter screen is fixedly installed on the inner side of the cooling furnace, a sealing door is sealed on the outer side of the cooling furnace, and a transparent oil collection bottle is threadedly installed at the bottom of the cooling furnace.

[0013] By adopting the above technical solution, the cooling furnace has the function of temporarily storing and cooling biochar. At the same time, the filter screen can filter the bio-oil produced during the pyrolysis process. The filtered bio-oil will be collected in a transparent oil collection bottle so that it can be catalytically cracked by connecting to an external catalytic modulation device to finally produce combustion oil that can be used for high-quality combustion.

[0014] In a preferred embodiment of the oil-filled mixed biomass storage carbon heating furnace of the present invention, a gas collecting pipe is fixedly installed on one side of the pyrolysis furnace, and one end of the gas collecting pipe is connected to an external catalytic modulation device for catalytic cracking.

[0015] In a preferred embodiment of the oil-filled mixed biomass storage carbon heating furnace of the present invention, a first baffle is movably installed on the inner side of the feed nozzle, and a second baffle is movably installed on the inner side of the pyrolysis furnace.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] 1. In this invention, during the biomass pyrolysis process, the generated bio-oil and pyrolysis gas are directly discharged separately and collected separately. Then, they are connected to an external advanced catalytic modulation device through pipelines to perform catalytic cracking treatment, which can be converted into high-quality fuel for use. It can generate usable energy simultaneously when making biochar, making the fuel easier to burn and greatly improving energy utilization efficiency.

[0018] 2. In this invention, the energy recovery and utilization during the pyrolysis process is highly efficient and refined. On the one hand, the heat leaked out during the pyrolysis process is cleverly captured and introduced into a special drying device to pre-dry the biomass material to be pyrolyzed, reducing the energy consumption of subsequent pyrolysis. On the other hand, for the biochar produced by pyrolysis, a scientific cooling method is adopted to use the heat released during its cooling process to heat water, thereby providing hot water for daily life or industrial production, significantly improving energy utilization efficiency and demonstrating the advantages of energy saving and environmental protection.

[0026] Please see Figures 1 to 5 The oil-filled mixed biomass storage carbon heating furnace includes a support rod 2 fixedly installed at the bottom of the feeding box 1 and a support ladder 7 fixedly installed on the right side of the heating furnace 3. A storage hopper 9 is fixedly installed on the top of the feeding box 1, and a feed nozzle 8 is fixedly installed at the bottom of the feeding box 1.

The feed nozzle 8 penetrates the top of the heating furnace 3 and communicates with the pyrolysis furnace 19. A drying hood 10 is fixedly installed on the top of the feeding box 1.

[0027] In this embodiment: the annular combustion seat 22 is located between the heating furnace 3 and the pyrolysis furnace 19 to ensure the continuity of the temperature inside the pyrolysis furnace 19. The annular combustion seat 22 is made of high-temperature resistant and corrosion-resistant materials, which can adapt to the high temperature and corrosive environment generated during combustion. The annular combustion seat 22 provides the heat required for the pyrolysis reaction. The pyrolysis furnace 19 provides an oxygen-deficient or oxygen-free pyrolysis environment for the biomass raw materials. The combustion control device set on the left side of the heating furnace 3 controls the ignition or extinguishing and adjusts the fire intensity. Multiple temperature detectors are set on the pyrolysis furnace 19 and are evenly distributed on the pyrolysis furnace 19 to improve the accuracy of temperature monitoring.

[0029] In this embodiment: the feed belt 17 is driven to rotate by the speed-regulating motor 16, which can continuously feed biomass raw materials into the pyrolysis furnace 19, and the feed amount can be controlled by adjusting the speed of the speed-regulating motor 16.

[0030] As a technical optimization of the present invention, a return air pipe 11 is fixedly installed at one end of the spiral tube 21, and one end of the return air pipe 11 is fixedly connected to the feeding box 1. An air outlet pipe 12 is fixedly installed at the other end of the spiral tube 21. One end of the air outlet pipe 12 is fixedly installed to the input end of the air pump 13, and the output end of the air pump 13 is connected to the drying hood 10.

[0031] In this embodiment: the drying hood 10 can dry the biomass raw materials that have leaked onto the feeding belt 17, reducing the moisture content of the raw materials and reducing the energy required during pyrolysis. The hot air in the spiral tube 21 is introduced into the drying hood 10 through the air outlet pipe 12 by the air pump 13. The drying hood 10 blows hot air to dry the raw materials, and then the air is drawn away by the return pipe 11 for reheating, thus performing a cycle of pre-drying treatment of the biomass raw materials.

[0032] As a technical optimization of the present invention, a spiral conical tube 20 is fixedly installed on the inner side of the cooling furnace 4, a water inlet head 14 is fixedly installed at one end of the spiral conical tube 20, and a water outlet head 15 is fixedly installed at the other end of the spiral conical tube 20.

[0033] In this embodiment, the water flowing inside the spiral conical tube 20 can cool the biochar produced by pyrolysis, and use the heat released during the cooling process to heat the water, thereby providing hot water for daily life or industrial production.

[0034] As a technical optimization of the present invention, a filter screen 18 is fixedly installed on the inner side of the cooling furnace 4, a sealing door 5 is sealed on the outer side of the cooling furnace 4, and an oil collection transparent bottle 6 is threadedly installed at the bottom of the cooling furnace 4.

[0035] In this embodiment: the biochar can be temporarily stored and cooled by the cooling furnace 4, and the bio-oil produced by pyrolysis can be filtered and collected into the transparent oil collection bottle 6 by the filter screen 18, so that it can be connected to an external catalytic modulation device for catalytic cracking to produce high-quality combustible fuel oil.

[0036] As a technical optimization of the present invention, a gas collecting pipe 23 is fixedly installed on one side of the pyrolysis furnace 19, and one end of the gas collecting pipe 23 is connected to an external catalytic modulation device for catalytic cracking.

[0037] In this embodiment, the pyrolysis gas generated by pyrolysis can be collected through the gas collecting pipe 23, and then catalytically cracked by connecting to an external catalytic modulation device to obtain a combustible gas that can be used normally.

[0038] As a technical optimization of the present invention, a first baffle 24 is movably installed on the inner side of the feed nozzle 8, and a second baffle 25 is movably installed on the inner side of the pyrolysis furnace 19.

[0039] In this embodiment: by setting the first baffle 24, the rotation handle on the outer side of the first baffle 24 can be rotated to adjust the sealing or opening operation of the first baffle 24 on the feed nozzle 8. When opened, the pre-dried biomass raw material can be leaked into the pyrolysis furnace 19 for pyrolysis treatment. By setting the second baffle 25, the rotation handle on the outer side of the second baffle 25 can be rotated to adjust the sealing or opening operation of the second baffle 25 on the bottom of the pyrolysis furnace 19. When opened, the pyrolyzed biochar can be discharged into the cooling furnace 4 for temporary storage and cooling treatment.

[0040] Working Principle: Biomass raw materials are stored in the storage hopper 9. The feed belt 17 is rotated by starting the speed-regulating motor 16, continuously feeding the biomass raw materials into the pyrolysis furnace 19. The feed rate is controlled by adjusting the speed of the speed-regulating motor 16. Hot air from the spiral tube 21 is circulated through the air outlet pipe 12 into the drying hood 10 via the air pump 13. The drying hood 10 dries the biomass raw materials that have leaked onto the feed belt 17. Air is then drawn away by the return air pipe 11 for reheating, thus performing a cyclical pre-drying process to reduce the moisture content of the biomass raw materials. Rotating the first baffle 24 seals the feed nozzle 8. The annular combustion seat 22 provides the necessary heat for the pyrolysis reaction. The heat provided by the annular combustion seat 22 also heats the air inside the spiral conical tube 20, facilitating drying in the drying hood 10. The pyrolysis furnace 19 provides an oxygen-deficient or oxygen-free pyrolysis environment for the biomass raw materials. During the pyrolysis of the biomass raw materials in the pyrolysis furnace 19, a pyrolysis reaction occurs under the action of heat, generating biochar, bio-oil, and pyrolysis gas. The pyrolysis gas generated by pyrolysis can be collected through the gas collection pipe 23 and catalytically cracked by connecting to an external catalytic modulation device to obtain combustible gas that can be used normally. After pyrolysis is completed, the second baffle 25 is rotated to open the bottom of the pyrolysis furnace 19 by rotating the handle, allowing the biochar to leak into the cooling furnace 4. The bio-oil is filtered through the filter screen 18 in the cooling furnace 4 and collected through the transparent oil collection bottle 6. The biochar can be taken out by opening the sealing door 5. The water flowing in the spiral conical tube 20 in the cooling furnace 4 can cool the biochar. The heated water can be provided for people to use as hot water, which is energy-saving, environmentally friendly, and rationally utilized.

[0041] Product processing and energy utilization: Biochar enters the charcoal box conditioning system for cooling and conditioning; bio-oil and pyrolysis gas enter the catalytic conditioning system for catalytic cracking, and then enter the combustion control system for combustion, providing heat energy for the pyrolysis system. The high-temperature flue gas generated by combustion passes through air preheating and water preheating devices, transferring heat to the air and water. The preheated air is used for combustion and drying, while hot water or steam is supplied to other equipment through the energy recovery system. After heat transfer, the flue gas enters the flue gas purification device for purification before being discharged.
