Description

Technical Field

[0001] The 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 crops such as straw, rice stalks, firewood, sawdust, peanut shells, melon seed shells, etc., which are crushed, mixed, extruded, dried and other processes to finally be 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 lot 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 curved return path, 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.

[0022] When in use, multiple split units 10 are connected together in sequence, multiple fireworks tubes 1 are connected in sequence, multiple sleeves 4 are connected in sequence, and fireworks generated by combustion in the combustion furnace pass through 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 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 achieving water heating.

[0023] Specifically, the isolation sleeve 5 is coaxially arranged with the fireworks tube 1, and an annular groove 51 is arranged on the inner wall of the isolation sleeve 5. The annular groove 51 is provided with connecting holes 52 connected with 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 plates 53 are arranged in the annular groove 51. The two arc 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 which is detachably connected to the isolation sleeve 5 is arranged at the bottom of the isolation sleeve 5, and when the sealing plate 61 is fixed at 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.

[0024] 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 arc plates 53, so that water can smoothly pass through the connecting holes 52 and enter the water outlet chamber 42 from the water inlet chamber 41. When it is necessary to clean the pyrotechnic tube 1, the two connecting holes 52 are closed by rotating the annular plate, and then the blocking plate 61 is removed, and 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 the blocking plate 61 are installed in turn, and then the arc plate 53 is rotated to open the two connecting holes 52 to work again. When the pyrotechnic tube 1 of a split unit 10 fails, only one split unit 10 needs to be replaced separately.

[0025] Specifically, this embodiment further includes an adjusting component 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 at the bottom of the isolation sleeve 5 .

[0026] The adjusting assembly 6 includes a rotating rod 62 and an adjusting plate 63, wherein 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, and two vertically arranged makeshift grooves 54 are arranged on the inner wall of the isolation sleeve 5 below the two connecting holes 52, and the makeshift grooves 54 penetrate downward through the isolation sleeve 5 and are connected with the annular groove 51, and the two arc-shaped plates 53 are provided with adjustment grooves 55 vertically penetrating the arc-shaped plates 53 on one side close to the axis of the isolation sleeve 5, when the arc-shaped plates 53 block the connecting hole 52 and close the connecting hole 52, the two sides of the makeshift groove 54 are aligned with the two sides of the adjustment groove 55, and 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 connecting hole 52.

[0027] 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 plates 53 and the arc plates 53 are rotated to a position offset from 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.

[0028] When the sealing ring 64 is compressed, the sealing ring 64 will apply a downward elastic force to the sealing plate 61, thereby applying 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.

[0030] 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 two adjacent split units 10 are connected; the pyrotechnic 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 two adjacent split units 10 are connected.

[0031] 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.
