Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of grain drying, and in particular to a biomass pyrolysis and gasification heating device for grain drying. Background Art
[0002] During grain production and storage, drying is crucial for ensuring grain quality and extending storage time. Traditional grain drying methods rely heavily on fossil energy, which is not only costly but also environmentally harmful. With increasing environmental awareness and the promotion of sustainable development concepts, the development and utilization of clean energy grain drying equipment has become an inevitable trend in the industry. Biomass pyrolysis and gasification heating equipment, with its clean, efficient, and renewable advantages, provides a new solution for the grain drying field.
[0003] Due to the raw materials, the combustible gas produced by pyrolysis contains impurities such as tar and dust. If the impurities accumulate too much in the filter bin after long-term use of the traditional filtering device, the flow of combustible gas entering the combustion chamber will be poor, resulting in unstable combustion and heat supply, which in turn affects the large fluctuations in the heat supply to the drying chamber, resulting in uneven drying of the grain and reduced efficiency. At the same time, when the filter plate is blocked, the staff cannot be informed in time. If effective measures are not taken in time, it will affect the subsequent equipment work. Summary of the Invention
[0004] According to the present invention, when a blockage occurs inside the filter plate, the pressure valve A will open, and the combustible gas will enter the guide tube A through the hose, so that the push rod will pop outward in the form of a pulse. When the push rod pops out, it will contact the filter plate. After the contact, the push rod will vibrate the filter plate, thereby shaking off the blocked dust, thereby ensuring the continuous and stable operation of the equipment, avoiding the poor circulation of the combustible gas due to the blockage of the filter plate, and thus affecting the combustion and heating link. At the same time, it can effectively improve the drying efficiency, prevent insufficient heat supply due to untimely cleaning, and ensure the smooth progress of grain drying.

[0014] Compared with the prior art, the present invention has the following beneficial effects: After long-term use of the present invention, if the filter plate is clogged, the combustible gas entering the gas storage tank will increase. When the combustible gas inside the gas storage tank increases to a certain pressure value, the pressure valve A will open, and the combustible gas will enter the guide tube A through the hose.

[0015] If the filter plate of the present invention is clogged and cannot be unblocked after long-term use, as the combustible gas pressure inside the filter bin gradually increases, the pressure valve B will be opened, so that the combustible gas enters the spare filter bin through the connecting pipe B for filtration, thereby preventing the operation chain of the heating equipment from being interrupted and ensuring that the combustible gas is continuously purified, so that the combustion chamber can continuously obtain cleaned combustible gas for combustion and heating.

When the push rod is pushed outward, it will knock on the filter plate, causing the impurities accumulated on the upper end of the filter plate to slide to one side and then be discharged through the discharge port, thereby preventing the impurities from accumulating on the upper end of the filter plate for a long time and making it difficult to clean. At the same time, after the push rod is fully extended, the empty groove will extend to the outside, and the empty groove will release part of the air pressure inside the guide tube B, so that after the pressure is released, the push rod will be reset to the inside of the guide tube B by the spring, thereby reciprocating and continuously knocking on the filter plate.

DETAILED DESCRIPTION
[0019] To make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0020] The present invention provides a biomass pyrolysis and gasification heating equipment for grain drying, comprising a biomass gasifier 1, a primary fan 2 is provided on one side of the biomass gasifier 1, a pump 3 is provided at the upper end of the biomass gasifier 1, one end of the pump 3 is connected to a delivery pipe 4, a branch pipe 5 is provided on one side of the pump 3, one end of the delivery pipe 4 is connected to a filter bin 6, an air storage tank 9 is provided on one side of the filter bin 6, a guide pipe A11 is provided inside the filter bin 6, a spare filter bin 14 is provided on the opposite side of the filter bin 6 of the air storage tank 9, a fan blade 18 is provided on the upper end of the spare filter bin 14, a guide pipe B20 is provided on the upper end of the filter bin 6, a hot air delivery pipe 24 is provided at the lower end of the filter bin 6, a secondary fan 26 is connected to one side of the hot air delivery pipe 24, an air distribution chamber 27 is provided on one side of the hot air delivery pipe 24, and one end of the air distribution chamber 27 is connected to a dryer 30.
[0021] In an optional embodiment, the primary fan 2 is fixedly connected to one side of the biomass gasifier 1, and the blowing end of the primary fan 2 passes through the biomass gasifier 1 and extends to the inside of the biomass gasifier 1. The pump 3 is fixedly connected to the upper end of the biomass gasifier 1, and the output end of the pump 3 is connected to the delivery pipe 4. One end of the delivery pipe 4 is fixedly connected to the center of the upper end of the biomass gasifier 1. When using the equipment, the crushed biomass is placed into the biomass gasifier 1, and the primary fan 2 is used to blow air to control the oxygen content in the biomass gasifier 1, so that the biomass is pyrolyzed and gasified. At the same time, the pump 3 will transport the combustible gas generated during the biomass gasification process to the rear end through the delivery pipe 4.
[0022] In an optional embodiment, the filter bin 6 is fixedly connected to the other end of the delivery pipe 4, and the lower end of the filter bin 6 is fixedly connected to the hot air delivery pipe 24. The inside of the filter bin 6 is fixedly connected to a filter plate 7, and the filter plate 7 is set as an inclined surface. One side of the filter bin 6 is fixedly connected to a connecting pipe A8, which passes through the filter bin 6 and extends to the inside. The other end of the connecting pipe A8 is fixedly connected to the gas storage tank 9. As described above, the delivery pipe 4 will transport the combustible gas to the inside of the filter bin 6, so that the combustible gas will be filtered through the filter plate 7 inside the filter bin 6 to prevent tar, dust and other impurities mixed in the combustible gas produced by pyrolysis. If it enters the burner directly without filtration, it may condense and adhere on the surface of the internal components of the burner, gradually accumulate to form dirt, and block the burner nozzle, thereby affecting the normal ejection and mixing of the combustible gas. The filtered combustible gas will continue to be transported to the rear end through the hot air delivery pipe 24. After the combustible gas enters the guide pipe A11 and enters the inside of the filter bin 6, part of the combustible gas will be transported to the inside of the gas storage tank 9 through the connecting pipe A8.
[0023] In an optional embodiment, a hose 10 is fixedly connected to the lower end of the gas storage tank 9, and a pressure valve A is provided at the connection between the hose 10 and the gas storage tank 9. The other end of the hose 10 is fixedly connected to a guide pipe A11, and the guide pipe A11 is embedded in the bottom end of the filter bin 6. The guide pipe A11 is fixedly connected to the filter bin 6, and a push rod 12 is movably connected inside the guide pipe A11. The pressure on the pressure valve A is less than the pressure on the pressure valve B. As described above, after long-term use, if the filter plate 7 is clogged, the combustible gas entering the gas storage tank 9 will increase. When the combustible gas inside the gas storage tank 9 increases to a certain pressure value , the pressure valve A will open, and the combustible gas will enter the guide tube A11 through the hose 10. Since the air pressure enters the guide tube A11 instantaneously, the push rod 12 will pop out in the form of a pulse. When the push rod 12 pops out, it will contact the filter plate 7. After contact, the push rod 12 will vibrate the filter plate 7, thereby shaking off the blocked dust, thereby ensuring the continuous and stable operation of the equipment, avoiding the poor circulation of combustible gas due to the blockage of the filter plate 7, and then affecting the combustion and heating link. At the same time, it can effectively improve the drying efficiency, prevent insufficient heat supply due to untimely cleaning, and ensure the smooth progress of grain drying.
[0024] In an optional embodiment, a connecting pipe B13 is fixedly connected to one side of the filter bin 6, and the connecting pipe B13 passes through the biomass gasification furnace 1 and extends to the interior of the filter bin 6. A pressure valve B is provided at the connection between the connecting pipe B13 and the filter bin 6. The other end of the connecting pipe B13 is fixedly connected to the spare filter bin 14. A partition 15 is fixedly connected to the outside of the connecting pipe B13, and a rotating shaft 16 is movably connected inside the partition 15. If the filter plate 7 is blocked and cannot be unblocked after long-term use, as the combustible gas pressure inside the filter bin 6 gradually increases, the pressure valve B will be opened, so that the combustible gas enters the spare filter bin 14 through the connecting pipe B13 for filtration, thereby preventing the operation chain of the heating equipment from being interrupted and ensuring that the combustible gas is continuously purified, so that the combustion chamber 25 continues to obtain cleaned combustible gas for combustion and heating. At the same time, switching the spare filter bin 14 can ensure the stability of the heat supply during the drying process, prevent heat supply fluctuations due to filter plate blockage, resulting in uneven grain drying, and reduced drying efficiency and grain quality.
[0025] In an optional embodiment, a connecting rod 17 is fixedly connected to the axis of the rotating shaft 16, and the connecting rod 17 extends to the outside through the partition groove 15. The end of the connecting rod 17 located on the outside is fixedly connected to the fan blade 18, and the lower end of the spare filter bin 14 is fixedly connected to the delivery pipe B19, and the other end of the delivery pipe B19 is fixedly connected to the hot air delivery pipe 24. After the combustible gas enters the connecting pipe B13, the wind force will drive the rotating shaft 16 to rotate. When the rotating shaft 16 rotates, it will synchronously drive the connecting rod 17 to rotate. When the connecting rod 17 rotates, it will synchronously drive the delivery pipe B19 to rotate, so that the staff can intuitively judge whether the filter plate 7 is blocked by the rotation of the delivery pipe B19, and thus clean or replace the filter plate 7 in time.
[0026] In an optional embodiment, one end of the branch pipe 5 is fixedly connected to the pump 3, and the other end is fixedly connected to the guide pipe B20. The guide pipe B20 is located at the upper end of the filter bin 6, and the guide pipe B20 is embedded in the filter bin 6. A push rod 21 is movably connected inside the guide pipe B20, and an empty groove 22 is provided at one end of the push rod 21. A spring 23 is fixedly connected to one end of the push rod 21, and the other end of the spring 23 is fixedly connected to the inner wall of the guide pipe B20. A discharge port is provided on one side of the filter bin 6. When the pump 3 is pumping gas, part of the gas will be transported to the inside of the guide pipe B20 through the branch pipe 5. After entering the guide tube B20, the push rod 21 will be pushed outward. When the push rod 21 is pushed outward, it will knock on the filter plate 7, causing the impurities accumulated on the upper end of the filter plate 7 to slide to one side and then be discharged through the discharge port, thereby preventing impurities from accumulating on the upper end of the filter plate 7 for a long time and making it difficult to clean. At the same time, after the push rod 21 is fully extended, the empty groove 22 will extend to the outside. The empty groove 22 will release part of the air pressure inside the guide tube B20, so that after the pressure is released, the push rod 21 will be reset to the inside of the guide tube B20 by the spring 23, thereby reciprocating and continuously knocking on the filter plate 7.
[0027] In an optional embodiment, the hot air delivery pipe 24 is fixedly connected to the combustion chamber 25 at one end away from the filter chamber 6, the lower end of the combustion chamber 25 is fixedly connected to a transmission pipe, the other end of the transmission pipe is fixedly connected to the air distribution chamber 27, the upper end of the air distribution chamber 27 is fixedly connected to a secondary fan 26, and the output end of the secondary fan 26 is fixedly connected to the combustion chamber 25. The hot air delivery pipe 24 will introduce the combustible gas generated during the biomass gasification process into the combustion chamber 25, so that the combustion chamber 25 is fully burned by the secondary fan 26, thereby removing residual tar and other organic pollutants, and at the same time introducing the generated high-temperature hot flue gas into the air distribution chamber 27 through the transmission pipe.
[0028] In an optional embodiment, two sets of air distribution dampers 28 are fixedly connected to the outside of the air distribution chamber 27, and an air duct 29 is fixedly connected to one side of the air distribution chamber 27. The air distribution chamber 27 is connected to the dryer 30 through the air duct 29. After the high-temperature hot flue gas enters the air distribution chamber 27, cold air is supplemented through the air distribution dampers 28 on both sides of the air distribution chamber 27, so that the high-temperature hot flue gas and the cold air are fully mixed, and the temperature of the hot air after air distribution is controlled. The hot air after air distribution is directly introduced into the dryer 30 through the air duct 29 for grain drying. A drainage pipe is fixedly connected to the outside of 30, and the other end of the drainage pipe is connected to the induced draft fan, so that the induced draft fan can generate strong suction, which promotes the continuous flow of hot air in the drying room and forms a good air circulation.
[0029] Working principle: When using the equipment, the crushed biomass is placed into the biomass gasification furnace 1, and the oxygen content in the biomass gasification furnace 1 is controlled by the primary fan 2 to blast air, so that the biomass is pyrolyzed and gasified. At the same time, the pump 3 will transport the combustible gas generated during the biomass gasification process to the rear end through the delivery pipe 4. The delivery pipe 4 will transport the combustible gas to the inside of the filter bin 6, so that the combustible gas will be filtered through the filter plate 7 inside the filter bin 6. The filtered combustible gas will continue to be transported to the rear end through the hot air delivery pipe 24. After the combustible gas enters the guide pipe A11 and enters the inside of the filter bin 6, part of the combustible gas will be transported to the inside of the gas storage tank 9 through the connecting pipe A8. After long-term use, if the filter plate 7 is clogged, the amount of combustible gas entering the gas storage tank 9 will increase. When the combustible gas inside the gas storage tank 9 increases to a certain pressure value, the pressure valve A will open, and the combustible gas will enter the guide tube A11 through the hose 10. Since the gas pressure enters the guide tube A11 instantaneously, the push rod 12 will pop out in the form of a pulse. When the push rod 12 pops out, it will contact the filter plate 7. If the filter plate 7 is clogged and cannot be cleared after long-term use, as the combustible gas pressure inside the filter chamber 6 gradually increases, the pressure valve B will open, allowing the combustible gas to enter the spare filter chamber 14 through the connecting pipe B13 for filtration, so that the combustion chamber 25 can continuously obtain clean combustible gas for combustion and heat supply. At the same time, after the combustible gas enters the connecting pipe B13, the wind will drive the rotating shaft 16 to rotate, and when the rotating shaft 16 rotates, it will synchronously drive the connecting rod 17 to rotate, and when the connecting rod 17 rotates, it will synchronously drive the delivery pipe B19 to rotate; When the pump 3 is pumping air, part of the gas will be transported to the inside of the guide tube B20 through the branch pipe 5. After the gas enters the guide tube B20, it will cause the push rod 21 to push outward. When the push rod 21 pushes outward, it will knock on the filter plate 7. After the push rod 21 is fully extended, the empty groove 22 will extend to the outside. The empty groove 22 will release part of the air pressure inside the guide tube B20. After the pressure is released, the push rod 21 will return to the inside of the guide tube B20 through the spring 23, thereby repeatedly knocking on the filter plate 7. The hot air delivery pipe 24 will introduce the combustible gas generated during the biomass gasification process into the combustion chamber 25, so that the combustion chamber 25 is fully burned through the secondary fan 26, thereby removing residual tar and other organic pollutants. At the same time, the high-temperature hot flue gas generated is introduced into the air distribution chamber 27 through the transmission pipe. After the high-temperature hot flue gas enters the air distribution chamber 27, cold air is added through the air distribution dampers 28 on both sides of the air distribution chamber 27 to fully mix the high-temperature hot flue gas and the cold air, thereby controlling the temperature of the hot air after the air distribution. The hot air after the air distribution is directly introduced into the dryer 30 through the air duct 29 for grain drying.
