[0030] The present invention provides the following embodiments

[0031] Example 1

[0032] The embodiment of the present invention provides a soot blower, such as Figure 1-Figure 2 As shown, it comprises: a base 1, a moving component 2 is arranged at the bottom of the base 1, a lifting mechanism 3 is arranged on the base 1, and a soot blowing component 4 and a dust suppression component 6 are arranged on the top of the lifting mechanism 3.

[0033] The working principle and beneficial effects of the above technical scheme are as follows: the moving component 2 can adjust the position of the soot blower, which is convenient for moving the soot blower to the position of the heat exchange tube that needs soot blowing. The base 1 supports the soot blowing component 4 and the dust reduction component 6. The lifting mechanism 3 can adjust the upper and lower heights of the soot blowing component 4 and the dust reduction component 6, so that the working height of the soot blower can be adjusted to cope with the soot blowing of heat exchange tubes at different heights. The soot blowing component 4 is adjusted in position to blow soot on the heat exchange tubes at the dust accumulation position. During the operation of the soot blowing component 4, the dust reduction component 6 can perform spraying, and the spray can adhere to the dust, thereby accelerating the settling speed of the dust falling from the wall of the heat exchange tube, while preventing the fine dust from flying away, reducing the range of dust generated during the soot blowing process, and preventing environmental pollution from affecting the health of the staff. It can efficiently and safely remove accumulated dust and enhance the heat exchange effect of the low-temperature economizer.

[0034] Example 2

[0035] On the basis of Example 1, Figure 1-Figure 2 As shown, the lifting mechanism 3 includes a spur gear 31, which is rotatably arranged in an adjusting cavity 11 opened inside the base 1, and the spur gear 31 is symmetrically rotatably arranged with a spur gear 2 32 and a spur gear 3 33 on the left and right sides, and the spur gear 31 is respectively meshed with the spur gear 2 32 and the spur gear 3 33, and a motor 34 is fixedly arranged on the top of the base 1, and the output end of the motor 34 is transmission-connected with the spur gear 31, and two threaded sleeves 35 are rotatably arranged on the top of the base 1, and the bottoms of the two threaded sleeves 35 are respectively fixedly connected with the spur gear 2 32 and the spur gear 3 33, and the tops of the two threaded sleeves 35 are respectively threadedly connected with a threaded rod 36, and the threaded rod 36 is symmetrically arranged on the left and right sides of the bottom of the sootblowing assembly 4 and the dust suppression assembly 6.

[0036] The working principle and beneficial effects of the above technical solution are as follows: when the height of the soot blower needs to be adjusted, the motor 34 in the lifting mechanism 3 is started, and the base 1 limits the rotation of the spur gear 31, the spur gear 32, and the spur gear 33.

[0037] Example 3

[0038] On the basis of Example 2, Figure 1-Figure 2As shown, the sootblowing assembly 4 includes an installation box 41, an equipment shell 42 is fixedly arranged in the equipment cavity of the installation box 41, a pressure pump 43 is fixedly arranged in the equipment cavity 421 of the equipment shell 42, an air inlet of the pressure pump 43 is communicated with an air inlet pipe 44, an air storage tank 51 is arranged above the base 1, the air inlet pipe 44 is communicated with the air storage tank 51, an air outlet of the pressure pump 43 is communicated with an air outlet pipe 45, the air outlet pipe 45 is a telescopic tube, and threaded sleeves 46 are symmetrically arranged on the upper and lower sides of one end of the equipment shell 42 away from the pressure pump 43, the threaded sleeves 46 are fixedly connected to the pulley 47 in the equipment cavity 421, and the pulleys 47 on the upper and lower sides are connected by belts 48.

[0039] The end of the threaded sleeve 2 46 away from the pulley 47 is threadedly connected to the threaded rod 2 49 in the working chamber, and the threaded rod 2 49 is fixedly connected to the working cylinder 50. The threaded sleeve 2 46 on the upper side is fixedly connected to the spur gear 4 52, and the spur gear 4 52 is meshed with the spur gear 5 53. The upper end of the working chamber is fixedly provided with a motor 2 54, and the output end of the motor 2 54 is transmission-connected to the spur gear 5 53.

[0041] The working principle and beneficial effects of the above technical solution are as follows: when the treated heat exchange tube is sootblown, after the sootblowing assembly 4 and the dust removal assembly 6 are adjusted to the target appropriate height, the motor 2 54 is started, the motor 2 54 drives the spur gear 5 53 to rotate, the spur gear 5 53 drives the spur gear 4 52 to rotate, the spur gear 4 52 drives the threaded sleeve 2 46 thereon to rotate, the threaded sleeves 2 46 on the upper and lower sides can rotate synchronously through the transmission of the pulley 47 and the belt 48, the threaded sleeve 2 46 drives the threaded rod 2 49 to move left and right when rotating, the threaded rod 2 49 drives the working cylinder 50 to slide left and right along the working shell, so that the working cylinder 50 is inserted into the treated heat exchange tube and moved to the position to be treated, the working cylinder 50 drives the sealing plate 64 to move left and right, the length of the air inlet pipe 44 and the spray pipe 62 is long enough or both are set as bellows, which ensures the extension and shortening of the working cylinder 50 and the installation box 41;

[0042] When the dust accumulation part inside the heat exchange tube to be treated is blown, the pressure pump 43 is started, so that the gas in the gas storage tank 51 enters the pressure pump 43 through the air inlet pipe 44 for pressurization, and the high-pressure gas enters the sound wave generator 55 through the air outlet pipe 45. The high-pressure gas is used as the energy source of sound waves or infrasound waves. The diaphragm in the sound wave generator 55 self-oscillates under the action of the high-pressure gas and resonates in the harmonic cavity, converting the potential energy of the compressed air into low-frequency sound energy, and transmitting the sound energy through the air medium through the sound wave tube 56 to the corresponding dust accumulation part, so that the sound wave has a vibrating effect on the ash. Due to the repeated action of the sound wave oscillation, the load applied to the ash extrusion cyclically changes. When a certain number of cyclic stresses is reached, the structure of the ash is destroyed due to fatigue, and then it sinks to the ash hopper under the action of gravity or is discharged from the heat exchange tube with the flue gas, thereby achieving the effect of cleaning.

[0043] Example 4

[0044] On the basis of Example 3, Figure 1-Figure 2 As shown, the dust reduction component 6 includes a liquid storage tank 61, which is fixedly arranged at the lower end of the working chamber. The liquid storage tank 61 is connected to the spray pipe 62. A suction pump 66 is provided between the liquid storage tank 61 and the spray pipe 62. The spray pipe 62 passes through the side end of the working cylinder 50 and is connected to the liquid collecting chamber 63. The liquid collecting chamber 63 is arranged inside a sealing plate 64. The sealing plate 64 is connected to the working cylinder 50. A plurality of spray heads 65 are evenly arranged circumferentially on the sealing plate 64. The plurality of spray heads 65 are connected to the liquid collecting chamber 63.

[0045] The working principle and beneficial effects of the above technical solution are as follows: the suction pump 66 is started while soot blowing is being performed, and the suction pump 66 draws the cleaning liquid in the liquid storage tank 61 into the liquid collecting chamber 63 through the spray pipe 62, and supplies liquid to the spray heads 65 evenly arranged in the circumferential direction. The spray heads 65 spray the cleaning liquid in the form of mist, and the spray can adhere to the ash residue separated from the inner wall of the heat exchange tube, thereby accelerating the settling speed of the ash residue. Under the action of gravity, the ash residue can quickly sink to the ash hopper for discharge, thereby improving the soot blowing efficiency and preventing fine dust from flying around, causing excessive dust in the air and affecting the environment.
