[0002] A biomass heating system is a system that uses biomass resources (such as crop residues, wood, municipal waste, etc.) to generate heat energy through technologies such as combustion, gasification, or pyrolysis. Its main purpose is to provide clean and renewable heating and hot water supplies for homes, industries, and cities.
[0003] Chinese patent document CN206459517U discloses a flue gas waste heat recovery and recycling device, including an air inlet pipe. A threaded sleeve is fitted onto the right end of the outer wall of the air inlet pipe, and a guide pipe is welded to the right end of the threaded sleeve. A filter barrel is longitudinally arranged in the inner cavity of the guide pipe. A stud is connected to the bottom of the filter barrel via a connecting rod.

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0026] like Figures 1-5 As shown, a waste heat recovery and recycling device for a biomass heating system includes a mechanism box 1. A discharge pipe 2 is fixedly connected to the right side of the mechanism box 1 near the bottom. An air inlet mechanism 3 is fixedly connected to the inner side of the upper wall of the mechanism box 1 near the left side. A water outlet mechanism 4 is fixedly connected to the inner side of the upper wall of the mechanism box 1 near the right side. A support base 5 is fixedly connected to the lower side of the mechanism box 1 near the front and rear sides.
[0027] The air intake mechanism 3 includes an air intake pipe 31, which is fixedly connected to the upper side of the mechanism box 1 near the left side via a first flange. The outer side of the air intake pipe 31 is movably sleeved on the inner side of the upper wall of the mechanism box 1 near the left side. Isolation covers 32 are fixedly connected to the front and rear sides of the inner side of the mechanism box 1 near the left side. The outer side of the air intake pipe 31 is movably sleeved on the inner side of the isolation cover 32. A water inlet pipe 33 is fixedly connected to the left side of the isolation cover 32. A first motor 34 is fixedly connected to the lower side of the mechanism box 1 near the left side. A stirring rack 35 is fixedly connected to the output end of the first motor 34, and the stirring rack 35 is located inside the isolation cover 32.
[0028] It should be noted that the first motor 34 drives the stirring frame 35 to rotate. When the stirring frame 35 rotates, it agitates the surrounding flue gas and water to mix them thoroughly. The air inlet pipe 31 is used to introduce flue gas. An exhaust pipe is provided on the left side of the mechanism box 1 near the upper side. The isolation cover 32 is used to isolate the agitation position so that the agitated water is only in one place, avoiding the water inside the mechanism box 1 from being agitated. This would make it difficult for the filter residue in the water to settle, thus increasing the filtration burden on the filter cover 46.
[0029] like Figure 4 As shown, the water outlet mechanism 4 includes a water outlet pipe 41. The outer side of the water outlet pipe 41 is movably sleeved on the inner side of the upper wall of the mechanism box 1 near the right side. A sealing plate 42 is fixedly connected to the outer side of the water outlet pipe 41 near the upper side. The sealing plate 42 is fixedly connected to the upper side of the mechanism box 1 through a second flange. Several ring-shaped hanging rods 43 are fixedly connected to the lower side of the sealing plate 42. A limiting plate 44 is fixedly connected to the lower side of the hanging rods 43. A fixing component 45 is movably sleeved on the outer side of the limiting plate 44. A filter cover 46 is fixedly connected to the lower side of the fixing component 45. The outer side of the water outlet pipe 41 is movably sleeved on the inner side of the filter cover 46 near the bottom.
[0030] It should be noted that the water outlet pipe 41 and the filter cover 46 are submerged in the water. The filter cover 46 is used to filter solid particles in the water, and then the water outlet pipe 41 discharges the water in the mechanism box 1.
[0031] like Figure 5 As shown, the fixing assembly 45 includes a fixing platform 451. The lower side of the fixing platform 451 is fixedly connected to the upper side of the filter cover 46. Several ring-shaped locking blocks 452 are movably sleeved on the side wall of the filter cover 46. The outer side of the limiting plate 44 is movably sleeved on the inner side of the fixing platform 451. The lower side of the locking blocks 452 is attached to the upper side of the limiting plate 44. A movable ring 453 is movably sleeved on the outer side of the fixing platform 451. Several ring-shaped guide rods 454 are fixedly connected near the edge of the lower side of the movable ring 453. The outer side of the guide rods 454 is slidably connected to the inner side of the locking blocks 452.
[0032] It should be noted that the movable ring 453 can drive all the guide rods 454 to move up and down. When the guide rods 454 are tilted, they push the locking block 452 to move along the inner diameter line of the fixed platform 451 when they move up and down. When the locking block 452 is located on the upper side of the limiting plate 44, the limiting plate 44 and the fixed platform 451 are fixed together.
[0033] like Figure 5 As shown, baffles 455 are movably sleeved on the outer sides of several rods 43, with the lower side of the baffles 455 overlapping the upper side of the movable rings 453. Pins 456 are movably sleeved on the inner sides of several rods 43, with the lower side of the pins 456 overlapping the upper side of the baffles 455. Two locking platforms 457 are fixedly connected to the upper sides of several baffles 455, and the outer side of the pins 456 is movably sleeved between the locking platforms 457.
[0034] It should be noted that when the baffle 455 is located above the movable ring 453, the movable ring 453 cannot move up or down, thus fixing the movable ring 453. The pin 456 is used to fix the position of the baffle 455, and the locking platform 457 is used to restrict the baffle 455, so that the baffle 455 cannot rotate around the hanging rod 43.
[0035] like Figure 4 As shown, a second motor 47 is fixedly connected to the lower side of several mechanism boxes 1 near the right side. The output end of the second motor 47 is fixedly connected to a transmission seat 48. A cleaning frame 49 is rotatably connected to the outer side of the filter cover 46. A socket 410 is fixedly connected to the lower side of the cleaning frame 49. The outer side of the transmission seat 48 is movably sleeved on the inner side of the socket 410.
[0036] It should be noted that the second motor 47 drives the transmission seat 48 to rotate. When the transmission seat 48 rotates, it drives the socket 410 to rotate. When the socket 410 rotates, it drives the cleaning frame 49 to rotate. When the cleaning frame 49 rotates, it removes the filter residue on the outside of the filter cover 46 to prevent the filter cover 46 from becoming clogged and causing a decrease in filtration capacity.
[0037] like Figure 4 As shown, the outer side of the socket 410 has several circularly distributed holes.
[0038] It should be noted that the round hole is used to allow the gas inside the socket 410 to be directly discharged from the round hole when the socket 410 is first inserted into the water.
[0039] like Figure 2 As shown, the lower inner surface of the mechanism box 1 is an inclined surface that slopes to the lower right.
[0040] It should be noted that the shape of the inner lower surface of the mechanism box 1 allows the filter residue to flow to the right along with the water when it is discharged from the inner side of the mechanism box 1.
[0041] The working principle of this utility model is as follows: First, the first motor 34 drives the stirring frame 35 to rotate. When the stirring frame 35 rotates, it agitates the surrounding flue gas and water, making them fully mixed. The air inlet pipe 31 is used to introduce flue gas. An exhaust pipe is located on the left side of the mechanism box 1 near the upper side. The isolation cover 32 is used to isolate the agitation position, so that the agitated water is concentrated in one place, avoiding the water inside the mechanism box 1 being agitated and the filter residue in the water being difficult to settle, which would increase the filtration burden on the filter cover 46. The first motor 34 drives the stirring frame 35 to rotate, causing the water and flue gas to be rapidly agitated and mixed, thereby allowing the particulate matter encapsulated in the flue gas to fully dissolve in the water, avoiding the problem of some particulate matter being discharged before it is dissolved. Finally, the water outlet pipe 41 and the filter cover 46 are inserted into the water. The filter cover 46 is used to filter solid particulate matter in the water, and then the water outlet pipe 41 drains the water in the mechanism box 1. The movable ring 453 can drive all the guide rods 454 to move up and down. The guide rods 454 are tilted, so that when the guide rods 454 move up and down, they push the locking block 452 to move along the inner diameter of the fixed platform 451. When the locking block 452 is above the limiting plate 44, the limiting plate 44 and the fixed platform 451 are fixed. When the baffle 455 is above the movable ring 453, the movable ring 453 cannot move up and down, so the movable ring 453 is fixed. The pin 456 is used to fix the position of the baffle 455. The locking platform 457 is used to limit the baffle 455, so that the baffle 455 cannot rotate around the hanging rod 43. The movable ring 453 is limited by the baffle 455, so that the locking block 452 fixes the filter cover 46. It is easy to install and easy to disassemble, avoiding the problems of difficult disassembly caused by the corrosion of connecting parts due to long-term contact with hot water.
[0042] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
