[0022] The following embodiments are used to further describe the specific embodiments of the present invention in conjunction with the accompanying drawings and examples. The following embodiments are only used to more clearly illustrate the technical solutions of the present invention and are not intended to limit the scope of protection of the present invention.

[0023] In the description of this utility model, it should be understood that the terms "upper," "lower," "front," "back," "left," "right," "horizontal," "vertical," "top," and "outer" and the like, indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate the description of this utility model and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations of this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Example

[0024] like Figure 1-5 As shown, the waste heat boiler cleaning device of the embodiment includes a waste heat boiler body 1, an economizer 2 arranged in the waste heat boiler body 1, and a spray assembly 3 arranged below or on the side of the economizer 2. A flue gas inlet 11 and a sewage outlet 12 are provided below the waste heat boiler body 1; the spray assembly 3 includes a plurality of spray heads 4, and the spray head 4 is provided with a water outlet 41 and a dust-proof column 42. The dust-proof column 42 cooperates with the water outlet 41 to close or open the water outlet 41. The dust-proof column 42 is slidably matched with the water outlet 41. The sliding direction of the dust-proof column 42 is parallel to the axial direction of the water outlet 41, and the water outlet 41 is arranged toward the economizer 2.

[0025] Through such a design, when the spray head 4 is not in use, the dust-proof column 42 is confined in the water outlet 41, closing the water outlet 41 to prevent smoke from entering the spray head; when the spray head 4 is in use, the dust-proof column 42 is separated from the water outlet 41, and the cleaning liquid can be sprayed out smoothly.

[0026] Specifically, the spray head 4 is fixedly arranged on the side wall of the waste heat boiler body 1, and the spray assembly 3 also includes a water pipe 5. The side wall of the waste heat boiler body 1 is provided with a through hole 13 for the branch pipe 51 of the water pipe 5 to pass through, and the branch pipe 51 of the water pipe 5 is connected to the spray head 4.

[0027] Through such a design, the purpose of water flow through the sprinkler head 4 is achieved.

[0028] Specifically, the sprinkler head 4 includes a panel 43 and a rear cover 44 fixedly connected to each other, the water outlet 41 is provided on the panel 43, the rear cover 44 is provided with a water inlet channel 45 communicating with the branch pipe 51, and the water inlet channel 45 is communicated with the water outlet 41.

[0029] Specifically, the sprinkler head 4 further includes a dustproof plate 46 , the rear cover 44 is provided with a guide column 47 , the dustproof plate 46 is slidably connected to the guide column 47 , and the dustproof column 42 is fixedly provided on the dustproof plate 46 .

[0030] Specifically, the water inlet channel 45 is provided through the guide column 47 .
