Technical Field
[0001] The present invention relates to the field of power generation equipment, and more specifically, to an integrated biomass unattended energy station. Background Art
[0002] A biomass energy station is a facility that uses biomass energy for energy production. It is mainly a thermal power generation or other energy production facility that uses biomass and its processed solid, liquid, and gas as fuel. It mainly includes biomass combustion power stations, biomass gasification power stations, biomass biogas power stations, etc. It is also a clean and renewable energy production facility. Among them, the biomass combustion power station is a facility that uses the biomass energy of biomass to generate electricity. The biomass fuel is directly burned in the boiler to generate heat energy to turn water into high-temperature and high-pressure steam, which then drives the steam turbine to rotate and drive the generator to generate electricity. For example, the Chinese patent with the announcement number CN114060797B discloses a biomass boiler equipment, which generates a vortex inside the boiler to greatly reduce the molten salt content in the flue gas, effectively improving the problem of molten salt damaging the boiler, and can also prevent the molten salt from condensing on the inner wall of the furnace, effectively reducing the difficulty of cleaning the molten salt; During the operation of biomass combustion boilers, high-temperature flue gas will continue to be generated as biomass burns. Existing energy stations usually discharge the flue gas after desulfurization and dust removal. However, since there is still a large amount of heat in the flue gas, the discharge of the flue gas will cause some heat loss, which will have an adverse effect on the energy conversion efficiency of the biomass. At the same time, affected by the amount of high-temperature flue gas generated, traditional steam boilers find it difficult to evaporate and heat water quickly, which affects the evaporation efficiency of water.

[0018] 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; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.
[0019] See also Figures 1 to 8 An integrated biomass unattended energy station includes a biomass boiler 11 and a recovery box 13, wherein a circulation sleeve 14 is fixedly connected to the lower side of the outer surface of the recovery box 13, an air guide pipe 12 is fixedly connected to the outer surface of the upper end of the biomass boiler 11, and the lower end of the air guide pipe 12 is fixedly connected to the outer surface of the circulation sleeve 14, and an evaporation component for producing water vapor is arranged inside the recovery box 13; The evaporation component includes a support plate 22 fixedly connected to the inner surface of the recovery box 13, the upper outer surface of the support plate 22 is fixedly connected to an evaporation tube 32, the lower end of the evaporation tube 32 passes through the lower side of the support plate 22, the upper outer surfaces of the plurality of evaporation tubes 32 are commonly fixedly connected to a water equalizing tank 26, the upper outer surface of the water equalizing tank 26 is fixedly connected to a liquid inlet pipe 16, the upper end of the liquid inlet pipe 16 passes through the upper side of the recovery box 13 and is fixedly connected to the recovery box 13, the upper outer surface of the support plate 22 is located outside the evaporation tube 32 and is fixedly connected to a heat preservation plate 24, and the outer surface of the evaporation tube 32 is fixedly connected to a heat conduction plate 33.
[0020] The upper end of the insulation plate 24 is fixedly connected to a support plate 25, and the inner side of the outer surface of the support plate 25 is fixedly connected to the outer surface of the water equalizing tank 26. The insulation plate 24 is in a circular ring shape, and the number of the evaporation tubes 32 is several groups and distributed in a ring array. The upper and lower ends of the evaporation tubes 32 are open, and the recovery box 13 is made of insulation material.
[0021] By adopting the above technical solution, the biomass boiler 11 is one of the core equipment of the biomass energy station. It generates steam through the heat energy released by biomass combustion, and uses steam to drive the steam engine to rotate, thereby driving the generator to generate electricity. The biomass boiler 11 will produce flue gas during the combustion process. For this purpose, a recovery box 13 is set. When working, the excess flue gas is transported to the inside of the recovery box 13 through the air duct 12. The flue gas will flow upward inside the recovery box 13. The recovery box 13 is fixedly supported by the support plate 22 to the evaporation tube 32. The evaporation tube 32 can be heated by the contact between the flue gas and the outer surface of the evaporation tube 32. The heat conduction plate 33 distributed in a ring array on the surface of the evaporation tube 32 can increase the contact area with the flue gas. At the same time, water is injected into the water equalization tank 26 through the liquid inlet pipe 16. The recovery box 13 is fixedly supported by the water balancing tank 26 through the second support plate 25. Water flows evenly into the evaporation tube 32 through the water balancing tank 26 and flows downward in the evaporation tube 32 in the form of a water film. At this time, the evaporation tube 32 heats and evaporates the water to generate water vapor, and then drives the generator to generate electricity through the steam. Several groups of annularly distributed evaporation tubes 32 can increase the contact area between water and the inner wall of the evaporation tube 32, which helps to improve the water evaporation efficiency. At the same time, since the water is continuously flowing, the probability of scale formation on the inner wall of the evaporation tube 32 can be reduced to a certain extent. By utilizing the waste heat of the flue gas of the biomass boiler 11 to continue to heat and evaporate the water, the amount of steam generated can be increased, which helps to reduce the heat loss of the biomass boiler 11, thereby improving the energy utilization efficiency of the biomass fuel.
[0022] like Figure 1 and Figure 3 As shown, a recovery component is arranged inside the recovery box 13, and the recovery component includes a collecting plate 20 fixedly connected to the inner surface of the recovery box 13, and the collecting plate 20 is located on the lower side of the support plate 22, and the outer surface of the collecting plate 20 is conical, and the outer surface of the recovery box 13 is located on the inner side of the circulation sleeve 14 and is provided with an air inlet groove 19, and the number of the air inlet grooves 19 is several groups and distributed in a ring array.
[0023] The upper end of the collecting plate 20 is fixedly connected to a fixing sleeve 39, the inner surface of the fixing sleeve 39 is fixedly connected to a connecting plate 40, the upper outer surface of the connecting plate 40 is fixedly connected to a push rod 41, the upper end of the push rod 41 is fixedly connected to an air guide plate 42, the air guide plate 42 is conical, the upper end of the fixing sleeve 39 passes through the upper side of the support plate 22 and is fixedly connected to the support plate 22, and the recovery component is used to recover the waste heat of biomass combustion.
[0024] By adopting the above technical scheme, the flue gas generated by the biomass boiler 11 is injected into the circulation sleeve 14 through the air guide pipe 12, and then enters the recovery box 13 through the annularly distributed air inlet grooves 19. The flue gas is guided by the collecting plate 20 and collected in the fixed sleeve 39, and continues to flow upward through the fixed sleeve 39. The fixed sleeve 39 supports the top rod 41 through the connecting plate 40, and fixes and supports the air guide plate 42 through the top rod 41. The air guide plate 42 can block the flue gas, so that the flue gas diffuses to the surroundings between the air guide plate 42 and the fixed sleeve 39, so that the flue gas is in full contact with the surface of each group of evaporation tubes 32, thereby effectively improving the heating effect of the flue gas on the evaporation tube 32. The insulation plate 24 between the support plate 1 22 and the support plate 2 25 can play a good heat insulation effect, which helps to maintain a high temperature of the evaporation tube 32, thereby reducing heat loss.
[0025] like Figure 1 and Figure 3 As shown, a reflux component is provided on the outside of the recovery box 13, and the reflux component includes a water pump 18 fixedly connected to the right side of the outer surface of the recovery box 13, and a reflux pipe 17 is fixedly connected to the right side of the outer surface of the liquid inlet pipe 16, and the lower end of the reflux pipe 17 is connected to the inside of the recovery box 13 through the water pump 18. An insulation layer is provided on the outside of the reflux pipe 17, and a heating strip 21 is fixedly connected to the outer surface of the upper end of the collecting plate 20. The number of the heating strips 21 is several groups and distributed in a ring array.
[0026] By adopting the above technical scheme, the flue gas will contact the lower surface of the collecting plate 20 after entering the recovery box 13, so that the collecting plate 20 can be heated by the flue gas. In the process of water flowing downward in the evaporation tube 32, part of the water will flow from the lower end of the evaporation tube 32 to the upper surface of the collecting plate 20. Flash evaporation will occur at the moment when the water falls downward from the evaporation tube 32, and high-temperature steam will be generated again at this time. The water will gather downward under the guidance of the collecting plate 20, and the heating strip 21 on the surface of the collecting plate 20 will contact the water. The water on the surface of the collecting plate 20 will be heated again by the heating strip 21, so that the remaining water maintains a high temperature, and then the water pump 18 sucks the water into the reflux pipe 17, and re-injects the water into the liquid inlet pipe 16 through the reflux pipe 17, so that the water and the residual heat in the water can be recycled and reused, thereby improving the heat utilization efficiency.
[0027] like Figure 4 , Figure 4 and Figure 8As shown, a material equalizing assembly for uniformly feeding water flow is provided on the inner side of the liquid inlet pipe 16, and the material equalizing assembly includes a mounting seat 34 fixedly connected to the inner surface of the liquid inlet pipe 16, and a movable rod 31 is rotatably connected to the middle part of the outer surface of the mounting seat 34, and a paddle 30 is fixedly connected to the upper side of the outer surface of the movable rod 31, and a scraper 43 is fixedly connected to the lower end of the outer surface of the movable rod 31. The scrapers 43 are divided into several groups and distributed in a ring array, and the scrapers 43 are located inside the water equalizing tank 26.
[0028] The outer surfaces of the support plate 1 22 and the support plate 2 25 are both provided with air guide grooves 23, the outer surface of the upper end of the water equalizing tank 26 is fixedly connected with a partition 27, the partition 27 is annular, and the outer surface of the partition 27 is evenly provided with through holes 28, and the outer surface of the upper end of the water equalizing tank 26 is evenly provided with notches 29, the upper left part of the outer surface of the recovery box 13 is fixedly connected with an exhaust pipe 15, the left side of the outer surface of the insulation board 24 is fixedly connected with an air outlet pipe 51, the left end of the air outlet pipe 51 passes through the outside of the recovery box 13 and is fixedly connected to the recovery box 13.
[0029] By adopting the above technical solution, during the working process, it is necessary to continuously inject an appropriate amount of water into the liquid inlet pipe 16. When the water is injected into the liquid inlet pipe 16, it will impact the paddle 30, thereby driving the movable rod 31 to rotate through the paddle 30. The liquid inlet pipe 16 supports the movable rod 31 for rotation through the mounting seat 34. During the rotation of the paddle 30, the two groups of water flows are stirred and mixed. After the water is injected into the water balancing tank 26 through the liquid inlet pipe 16, the movable rod 31 will drive the scraper 43 to rotate synchronously. The rotation of the scraper 43 can move the water inside the water balancing tank 26, so that the water can evenly enter each group of evaporation tubes. 32, thereby improving the evaporation efficiency of the water flow in the evaporator tube 32, the water vapor generated inside the evaporator tube 32 will flow to the inside of the water equalizing tank 26, and diffuse to the inside of the partition 27 through the notch 29 on the upper surface of the water equalizing tank 26, and then the water vapor passes through the through hole 28 into the space between the partition 27 and the recovery box 13. The water vapor generated by the evaporation of the water on the surface of the collecting plate 20 due to heat will flow upward through the air guide grooves 23 on the surfaces of the support plates 1 22 and 25, thereby transporting the water vapor inside the recovery box 13 to the steam generator through the exhaust pipe 15, and the smoke inside the insulation plate 24 is discharged to the outside of the recovery box 13 through the exhaust pipe 51.
[0030] like Figure 3 , Figure 6 and Figure 7As shown, a scraping assembly for cleaning the inside of the evaporator tube 32 is provided on the inner side of the evaporator tube 32, and the scraping assembly includes a reciprocating screw rod 35 fixedly connected to the upper end of the inner surface of the water equalizing tank 26, and the lower end of the reciprocating screw rod 35 passes through the inner side of the evaporator tube 32 and is fixedly connected to a block 38, and the outer surface of the reciprocating screw rod 35 is rotatably connected to a connecting seat 36, and the outer surface of the connecting seat 36 is fixedly connected to a swing rod 37, and the number of the swing rods 37 is several groups and distributed in a ring array, and the outer surface of the swing rod 37 is in rotational contact with the scraper 43.
[0031] The outer surface of the reciprocating screw rod 35 is located below the connecting seat 36 and is connected by a spiral sleeve 47, the outer surface of the spiral sleeve 47 is magnetically fixedly connected to the movable seat 45, the outer surface of the movable seat 45 is symmetrically provided with slide grooves 48, the inner surface of the slide grooves 48 is slidably connected to a top block 50, the inner surface of the slide grooves 48 is fixedly connected to one end of the reciprocating screw rod 35 with a spring 49, the top block 50 is fixedly connected to one end away from the spring 49 with a cleaning plate 46, and the cleaning plate 46 is made of elastic and high temperature resistant material.
[0032] A guide rod 44 is fixedly connected to the outer surface of the lower end of the connecting seat 36. The guide rod 44 passes through the upper and lower ends of the movable seat 45 and is slidably connected to the movable seat 45. The lower end of the guide rod 44 is fixedly connected to the stopper 38. The number of the heat conducting plates 33 is several groups and the annular array is distributed on the outside of the evaporation tube 32.
[0033] By adopting the above technical solution, scale will be generated in the evaporation tube 32 during long-term operation, and the scale will not only destroy the shape of the water flow on the inner wall of the evaporation tube 32, but also have an adverse effect on the heat transfer of the evaporation tube 32. The water equalization tank 26 can fix and support the reciprocating screw rod 35. The scraper 43 will rotate and contact with the surface of the swing rod 37 during the rotation, so that the connecting seat 36 is driven by the swing rod 37 to rotate on the surface of the reciprocating screw rod 35. When the inside of the evaporation tube 32 is cleaned, the movable seat 45 is magnetically fixed to the spiral sleeve 47. The mounting seat 34 will drive the movable seat 45 to rotate synchronously through the guide rod 44 during the rotation, and the spiral sleeve 47 is driven to rotate synchronously through the movable seat 45. The spiral sleeve 47 is connected to the reciprocating screw rod 35 through a spiral transmission, and will reciprocate up and down along the surface of the reciprocating screw rod 35 during the rotation. The sliding connection between the guide rod 44 and the movable seat 45 can guide the movable seat 45, so that the sliding of the movable seat 45 is more stable. The sliding groove 48 drives the top block 50 to move synchronously, and the cleaning plate 46 is fixedly supported by the top block 50. During the rotation process, the movable seat 45 drives the cleaning plate 46 to rotate synchronously through the top rod 41, so that the cleaning plate 46 can rotate and contact with the inner wall of the evaporation tube 32, which can effectively scrape and clean the scale on the inner wall of the evaporation tube 32, thereby effectively reducing the residual scale, while ensuring the quality of water film forming, it can also improve the heat conduction efficiency of the evaporation tube 32. The movable seat 45 can apply a certain elastic force to the cleaning plate 46 through the spring 49, so that the cleaning plate 46 maintains a close contact with the inner wall of the evaporation tube 32, thereby further improving the cleaning quality of the inner wall of the evaporation tube 32. When the evaporation tube 32 stops cleaning, the movable seat 45 and the cleaning plate 46 are kept at the uppermost side, and then the magnetic attraction between the spiral sleeve 47 and the movable seat 45 is released, so that the movable seat 45 rotates along the surface of the spiral sleeve 47, and the spiral sleeve 47 remains stationary, thereby avoiding the influence of the cleaning component on the quality of water film forming.
[0034] Instructions for use: During operation, excess smoke is transported to the inside of the recovery box 13 through the air guide 12, and the smoke is collected into the inside of the fixed sleeve 39 under the guidance of the collecting plate 20. At the same time, a proper amount of water is continuously injected into the inside of the liquid inlet pipe 16. After the water is injected into the water equalizing tank 26 through the liquid inlet pipe 16, the water in the water equalizing tank 26 can be moved by the rotation of the scraper 43, so that the water can evenly enter the inside of each group of evaporation tubes 32. The evaporation tube 32 can be heated by the contact between the smoke and the outer surface of the evaporation tube 32, and flows downward in the evaporation tube 32 in the form of a water film. At this time, the evaporation tube 32 heats the water and evaporates it. Water vapor, part of the water will flow from the lower end of the evaporation tube 32 to the upper surface of the collecting plate 20, and flash evaporation will occur at the moment when the water falls downward from the inside of the evaporation tube 32. At this time, high-temperature steam will be generated again, and the water will be re-injected into the liquid inlet pipe 16 through the reflux pipe 17. During the rotation process, the movable seat 45 will drive the cleaning plate 46 to rotate synchronously through the top block 50, so that the cleaning plate 46 can effectively scrape and clean the scale on the inner wall of the evaporation tube 32 through rotational contact with the inner wall of the evaporation tube 32, thereby effectively reducing the residual scale, while ensuring the quality of water film forming, it can also improve the heat conduction efficiency of the evaporation tube 32.
