Description

Technical Field

[0001] The present invention relates to the technical field of flue heat exchanger cleaning, and particularly to an anti - ash - accumulation device for a flue heat exchanger. Background Art

[0002] A flue heat exchanger is a device used to improve thermal efficiency, usually used in the industrial and energy fields. Its main function is to recover and utilize the heat in the waste gas, thereby improving the overall energy efficiency of the system; the flue heat exchanger recovers the heat in the waste gas by transferring the heat in the waste gas to another medium (such as water or air). This recovered heat can be used to heat process fluids or pre - heat fuels. By recovering the heat in the waste gas, the flue heat exchanger can reduce the demand for external heat sources, thereby reducing energy consumption and operating costs.

[0003] During use, most of the low - temperature economizer and phase - change heat exchanger renovations are installed as the main devices of energy - saving technologies in the extended section of the flue gas at the tail of the power plant boiler. As low - temperature waste - heat recovery devices, they have shown good energy - saving performance; however, the above - mentioned two flue heat exchanger devices cause serious ash accumulation inside the flue due to the change of the flue gas flow field, which easily causes blockage of the flue.

[0027] To make the above objects, features, and advantages of the present invention more obvious and understandable, the following will provide a detailed description of the specific embodiments of the present invention in conjunction with the drawings of the specification.

[0028] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Those skilled in the art can make similar generalizations without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0029] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that can be included in at least one implementation manner of the present invention. The appearances of "in one embodiment" in different places in this specification do not all refer to the same embodiment, nor are they separate or alternative embodiments that exclude each other with other embodiments.

[0030] Example 1

[0031] Reference Figure 1 This is the first embodiment of the present invention. This embodiment provides a dust accumulation prevention device for a flue heat exchanger, which can achieve the effect of preventing flue blockage. It includes a cleaning component 100, which includes a main body 101, a housing 102 arranged on the main body 101, a rotating component 103 arranged in the housing 102. The rotating component 103 can prevent dust accumulation in the flue heat exchanger. A linkage component 104 is movably connected to the rotating component 103. The linkage component 104 can drive the operation of the movable component 105, and a movable component 105 arranged on the linkage component 104. When the movable component 105 operates, it can knock on the inside of the main body 101, so that the dust accumulated in the flue heat exchanger becomes loose.

[0032] A conversion component 200, which includes a limit component 201 arranged on the rotating component 103. The limit component 201 can adjust the state of the rotating component 103, an adjustment component 202 arranged on one side of the limit component 201, and a driving component 203 arranged on the rotating component 103. The driving component 203 can drive the operation of the rotating component 103.

[0033] In summary, by using the operation of the rotating component 103 to prevent dust accumulation in the flue heat exchanger, the dust will float up after being fanned. While the rotating component 103 rotates, it drives the movable component 105 to knock on the inside of the main body 101, so that the dust accumulated in the flue heat exchanger becomes loose, and the dust detaches from the main body 101. And by using the adjustment component 202, the movable component 105 can also stop operating when the rotating component 103 operates, reducing the vibration of the main body 101.

[0034] Example 2

[0035] Reference Figures 2 to 5 This is the second embodiment of the present invention. Different from the previous embodiment, this embodiment provides a dust accumulation prevention device for a flue heat exchanger, which solves the problem of serious dust accumulation in the flue in the prior art and easy flue blockage. The rotating component 103 includes a rotating shaft 103a rotatably connected to the housing 102, a movable rod 103b fixedly connected to one end of the rotating shaft 103a, and multiple groups of baffles 103c fixedly connected to the rotating shaft 103a. The multiple groups of baffles 103c are arranged in a circular array on the rotating shaft 103a. When the rotating shaft 103a rotates, it drives the baffles 103c to rotate, and the dust accumulated in the heat exchanger will be fanned by the wind speed driven by the rotation of the baffles 103c, so that the dust will not adhere to the inside of the flue heat exchanger.

[0036] Further, the linkage component 104 includes a lever 104a rotatably connected to the housing 102, a connecting rod 104b fixedly connected to one side of the lever 104a, the connecting rod 104b and the lever 104a are arranged in a staggered manner, a hinge rod 104c rotatably connected below the connecting rod 104b, and a limiting block 104d fixedly connected to the hinge rod 104c. The hinge rod 104c is rotatably connected to the inside of the housing 102 through a shaft.

[0037] Further, the movable component 105 includes a striking rod 105a slidably connected below the limiting block 104d, a sliding rod 105b arranged on one side of the striking rod 105a. The striking rod 105a is slidably connected to the side wall of the housing 102 through the sliding rod 105b to ensure that the sliding rod 105b slides linearly on the housing 102. A chute 105c is opened on the striking rod 105a, and a plurality of groups of triangular blocks 105d are fixedly connected to both sides of the striking rod 105a.

[0038] Further, there are two groups of the plurality of groups of triangular blocks 105d arranged on the side close to the limiting block 104d and one group arranged on the other side. The triangular block 105d is also provided with a side 105c-1, and a hook-shaped block 105c-2 fixedly connected to the limiting block 104d, and the hook-shaped block can be mutually attached to the right-angle side of the triangular block 105d.

[0039] Further, the movable component 105 also includes a clamping block 105e fixedly connected in the chute 105c, the clamping block 105e is fixedly connected to the housing 102, and a spring 105f fixedly connected to the clamping block 105e. The spring 105f is fixedly connected between the end of the chute 105c and the clamping block 105e.

[0040] Specifically, when the lever 104a rotates and passes through the hinge rod 104c during the rotation process, the hinge rod 104c will rotate under the drive of the connecting rod 104b. While the hinge rod 104c rotates, it drives the limiting block 104d to deflect. Due to the elastic potential energy of the spring 105f, when the limiting block 104d deflects, the fixation of the striking rod 105a is released. Subsequently, with the cooperation of the elastic potential energy of the spring 105f, the striking rod 105a slides back and forth to strike the main body 101 multiple times until the hinge rod 104c fits with another group of triangular blocks 105d on the same side, driving the striking rod 105a to move back to its original position, and the hook-shaped block restores the striking rod 105a again.

[0041] In summary, when the rotating shaft 103a rotates, it not only drives the plurality of blocking blocks 202b to fan the dust, but also the striking rod 105a cooperates to strike the main body 101, so that the dust adhered to the main body 101 becomes loose, making the dust float inside the main body 101, preventing the blockage of the flue.

[0042] The remaining structure is the same as that of Embodiment 1.

[0043] Embodiment 3

[0044] Referring to Figures 3 to 6 , which is the third embodiment of the present invention. Different from the previous embodiment, this embodiment provides a dust accumulation prevention device for a flue heat exchanger, which solves the problem of adjusting the movable component 105. It includes a limiting component 201, which includes a connecting rod 201a fixedly connected to the movable rod 103b. A spring 105f is arranged at the end of the connecting rod 201a. The connecting rod 201a is installed at the end of the rotating shaft 103a. A limiting ring 201b fixedly connected to the connecting rod 201a, and a cavity 201c opened at one end of the rotating shaft 103a. The connecting rod 201a is rotatably connected in the cavity 201c.

[0045] Furthermore, the adjusting component 202 includes a groove 202a opened on the movable rod 103b, multiple groups of stoppers 202b fixedly connected in the groove 202a, and a support rod 202c hinged to the stoppers 202b.

[0046] Furthermore, a clamping groove 202d, a channel 202e, and a clamping slot 202f are arranged between multiple groups of stoppers 202b.

[0047] Furthermore, the driving component 203 includes a connecting seat 203a fixedly connected to the housing 102, and a motor 203b fixedly connected to the connecting seat 203a. The output shaft of the motor 203b is connected to the rotating shaft 103a.

[0048] Specifically, when the operator pushes the movable rod 103b, the end of the movable rod 103b enters the cavity 201c, so that the movable rod 103b is connected to the rotating shaft 103a. At the same time of connection, due to the displacement of the movable rod 103b, the support rod 202c on the movable rod 103b rotates. The end of the support rod 202c enters the clamping groove 202d from the channel 202e, thereby fixing the position where the movable rod 103b is pushed inward by the support rod 202c and preventing the rotating shaft 103a from disengaging from the movable rod 103b during rotation.

[0049] In summary, the motor 203b drives the rotating shaft 103a to rotate. During rotation, the linkage component 104 will operate together. Then, during rotation, the knocking rod 105a continuously knocks the main body 101, causing the main body 101 to vibrate and shake off the dust. When the dust vibrates to a certain degree, the operator can press the movable rod 103b so that the movable rod 103b disengages from the cavity 201c. At this time, while the rotating shaft 103a rotates, the dial rod 104a stops rotating, and the knocking rod 105a cannot operate. The two components are separate individuals and are no longer linked, so that the vibration degree of the main body 101 can be adjusted arbitrarily.

[0050] The remaining structure is the same as that of Embodiment 2.
