Description

Technical Field

[0001] The present invention relates to a boiler, and more particularly to a biomass environmentally friendly boiler. Background Art

[0002] Biomass boilers are widely used due to their low price and low operating cost. Biomass pellet fuel is made from discarded agricultural products such as straw, rice stalks, firewood, sawdust, peanut shells, melon seed shells, etc., which are crushed, mixed, extruded, dried, and finally made into pelletized fuel.

[0003] In traditional biomass boilers, the fire pipe connected to the combustion furnace has two to three bends in the boiler body, so that the high-temperature flue gas can more fully pass through the outer wall of the fire pipe to transfer heat to the water in the boiler to form heat exchange.

[0004] However, biomass fuel will produce a large amount of dust and tar during the combustion process. Long-term accumulation can easily lead to blockage of the fire pipe. In addition, due to the setting of the bend return, it is not easy to clean the fire pipe after it is blocked, which greatly increases the failure rate of the boiler and reduces the service life of the boiler. Summary of the Invention

[0033] Example: A biomass environmentally friendly boiler, see attached Figure 1 -Attached Figure 6 , including a split unit 10, the split unit 10 includes multiple, multiple split units 10 are connected together in sequence to form a boiler; the split unit 10 includes a fireworks tube 1, an isolation plate 2, a sleeve 4, a partition plate 3 and an isolation sleeve 5, the fireworks tube 1 is set as a circular tube with a vertical axis, the top of the fireworks tube 1 is closed, and the bottom is provided with a maintenance plate 13 that is detachably connected to the fireworks tube 1; the fireworks tube 1 is fixedly connected with an isolation plate 2 that vertically passes through the fireworks tube 1, the top and both sides of the isolation plate 2 are fixed to the inner wall of the fireworks tube 1, the isolation plate 2 separates the fireworks tube 1 into a fire inlet chamber 11 and a fire outlet chamber 12, and the bottom of the isolation plate 2 is connected to the maintenance plate 13 A space is left between them to connect the fire inlet chamber 11 and the fire outlet chamber 12; the sleeve 4 is sleeved on the outside of the fireworks tube 1 and is coaxial with the fireworks tube 1, and water flows through the sleeve 4; a partition plate 3 is provided in the sleeve 4, which is fixedly connected to the outside of the fireworks tube 1 and is located in the same plane as the isolation plate 2. The top, bottom and both sides of the partition plate 3 are fixedly connected to the inner wall of the sleeve 4, and the partition plate 3 divides the space between the sleeve 4 and the fireworks tube 1 into a water inlet chamber 41 and a water outlet chamber 42. A connecting channel 43 connecting the water inlet chamber 41 and the water outlet chamber 42 is provided under the fireworks tube 1; the isolation sleeve 5 is fixedly connected to the bottom of the fireworks tube 1 and vertically passes through the bottom of the sleeve 4.

[0034] When in use, multiple split units 10 are connected together in sequence, multiple fireworks tubes 1 are connected in sequence, and multiple sleeves 4 are connected in sequence. The fireworks generated by the combustion in the combustion furnace pass through the multiple fireworks tubes 1 in sequence, and pass through the fire inlet chamber 11 and the fire outlet chamber 12 in a single fireworks tube 1 in sequence; water also passes through the multiple sleeves 4 in sequence, and passes through the water inlet chamber 41 and the water outlet chamber 42 in a single sleeve 4, so that the heat carried by the fireworks is transferred to the water in the water inlet chamber 41 and the water outlet chamber 42, thereby heating the water.

[0035] Specifically, the isolation sleeve 5 is coaxially arranged with the fireworks tube 1, and an annular groove 51 is provided on the inner wall of the isolation sleeve 5. The annular groove 51 is provided with connecting holes 52 connected to the water inlet chamber 41 and the water outlet chamber 42 on both sides thereof close to the water inlet chamber 41 and the water outlet chamber 42. Two arc-shaped plates 53 are provided in the annular groove 51. The two arc-shaped plates 53 can rotate around the axis of the isolation sleeve 5 in the annular groove 51 to realize the closing and opening of the connecting holes 52; a sealing plate 61 is provided at the bottom of the isolation sleeve 5, which is detachably connected to the isolation sleeve 5. When the sealing plate 61 is fixed to the bottom of the isolation sleeve 5 and the two connecting holes 52 are opened, the connecting holes 52 and the inner cavity of the isolation sleeve 5 form a connecting channel 43.

[0036] When the boiler is in use, the blocking plate 61 is connected to the bottom of the isolation sleeve 5 and the two connecting holes 52 are opened by rotating the two curved plates 53, allowing water to smoothly pass through the connecting holes 52 and enter the water outlet chamber 42 from the water inlet chamber 41. When the pyrotechnic tube 1 needs to be cleaned, the two connecting holes 52 are closed by rotating the annular plate, and then the blocking plate 61 is removed. Then, the maintenance plate 13 at the bottom of the pyrotechnic tube 1 is removed to clean the inner wall of the pyrotechnic tube 1. After cleaning, the maintenance plate 13 and blocking plate 61 are installed in sequence, and then the curved plate 53 is rotated to open the two connecting holes 52 and the boiler can resume operation. When the pyrotechnic tube 1 of a split unit 10 fails, only the split unit 10 needs to be replaced.

[0037] Specifically, this embodiment further includes an adjusting assembly 6 , which is used to adjust the rotation of the arc plate 53 in the annular groove 51 and can fix the blocking plate 61 to the bottom of the isolation sleeve 5 .

[0038] The adjusting assembly 6 includes a rotating rod 62 and an adjusting plate 63. The rotating rod 62 is coaxial with the isolation sleeve 5 and is rotatably connected to the sealing plate 61; the adjusting plate 63 is vertically arranged and passes through the axis of the rotating rod 62. Two vertically arranged makeshift grooves 54 are provided on the inner wall of the isolation sleeve 5 below the two communicating holes 52. The makeshift grooves 54 pass through the isolation sleeve 5 downward and are connected to the annular groove 51. The two arc-shaped plates 53 are provided with adjustment grooves 55 that vertically pass through the arc-shaped plates 53 on one side near the axis of the isolation sleeve 5. When the arc-shaped plate 53 blocks the communicating hole 52 and closes the communicating hole 52, the two sides of the makeshift groove 54 are aligned with the two sides of the adjustment groove 55. The two ends of the adjusting plate 63 can be inserted into the two makeshift grooves 54 and can be inserted upward into the two adjustment grooves 55 when the two arc-shaped plates 53 block the communicating hole 52.

[0039] The diameter of the blocking plate 61 is larger than the diameter of the isolation sleeve 5. A sealing ring 64 is fixedly connected to the top of the isolation sleeve 5, and the sealing ring 64 presses the bottom of the sleeve 4; a sealing groove 44 is provided at the bottom of the sleeve 4, and the sealing ring 64 can be embedded in the sealing groove 44; when the two ends of the adjusting plate 63 are inserted into the two adjusting grooves 55 of the two arc-shaped plates 53 and the arc-shaped plate 53 is rotated to a position staggered with the connecting hole 52, the adjusting plate 63 is pressed against the bottom of the annular groove 51, and the sealing ring 64 is compressed at this time.

[0040] When the sealing ring 64 is compressed, the sealing ring 64 will apply a downward elastic force to the sealing plate 61, and thus apply pressure to the pressure regulating plate to press against the bottom of the annular groove 51. The contact between the pressure regulating plate and the bottom of the annular groove 51 ensures that the sealing ring 64 is always in a compressed state, thereby ensuring the sealing effect of the sealing ring 64.

[0041] Specifically, the water inlet chamber 41 of the sleeve 4 is located outside the fire outlet chamber 12 of the pyrotechnic tube 1, and the water outlet chamber 42 of the sleeve 4 is located outside the fire inlet chamber 11 of the pyrotechnic tube 1. The fire inlet chamber 11 of the pyrotechnic tube 1 close to the combustion furnace is connected to the combustion furnace, while the fire outlet chamber 12 of the pyrotechnic tube 1 far from the combustion furnace is connected to the outside world; the water inlet chamber 41 of the sleeve 4 far from the combustion furnace is connected to the external cold water source, while the water outlet chamber 42 of the sleeve 4 close to the combustion furnace is connected to the application equipment of hot water; as the fireworks flow from the fire inlet chamber 11 to the fire outlet chamber 12 in the pyrotechnic tube 1, and from the pyrotechnic tube 1 close to the combustion furnace to the pyrotechnic tube 1 far from the combustion furnace, the temperature of the fireworks will gradually decrease, and the water flowing in the direction opposite to the flow direction of the fireworks will first be preheated by the low-temperature fireworks, and then heated by the high-temperature fireworks, thereby improving the utilization rate of the heat in the fireworks.

[0042] Specifically, the sleeve 4 is fixedly connected to the outside with a water inlet pipe 411 and a water outlet pipe 421 which are respectively connected to the water inlet chamber 41 and the water outlet chamber 42, and the water inlet pipe 411 and the water outlet pipe 421 of the two adjacent split units 10 are connected; the fireworks tube 1 is fixedly connected to the outside with a fire inlet pipe 111 and a fire outlet pipe 121 which pass through the sleeve 4, and the fire inlet pipe 111 and the fire outlet pipe 121 are respectively connected to the fire inlet chamber 11 and the fire outlet chamber 12, and the adjacent fire inlet pipes 111 and the fire outlet pipes 121 of the two adjacent split units 10 are connected.

[0043] Specifically, the bottom of the pyrotechnic tube 1 is fixedly connected to a mounting rod 14 located below the isolation plate 2, and the maintenance plate 13 is detachably connected to the bottom of the mounting rod 14 by bolts. When the maintenance plate 13 is fixed to the bottom of the mounting rod 14, the maintenance plate 13 seals the bottom of the pyrotechnic tube 1.

[0044] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, various improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
