[0002] The boiler can produce hot water or steam through waste heat recovery to supply other work sections. Due to the large amount of dust in the flue gas, the dust will adhere to the membrane wall inside the waste heat boiler, resulting in a significant reduction in the heat exchange efficiency of the membrane wall of the waste heat boiler, such as patent application number CN201911365440.6. A waste heat boiler cleaning device and a waste heat boiler, including a cleaning mechanism, a power mechanism, a gap adjustment mechanism, and a PLC control cabinet. The present invention controls the power mechanism through the PLC control cabinet to drive the cleaning mechanism to reciprocate along the membrane wall in the waste heat boiler, thereby cleaning the dust adhered to the membrane wall. After the cleaning mechanism is worn, the spacing between the cleaning mechanism and the membrane wall that needs to be adjusted is set on the PLC control cabinet, and the gap is controlled by the PLC control cabinet. The gap adjustment mechanism pushes the cleaning mechanism to move as a whole, and can adjust the contact distance between the cleaning component and the membrane wall, so that the cleaning component continues to clean the membrane wall, which can reduce the operating cost of frequent replacement of cleaning equipment; according to actual cleaning needs, the contact distance between the cleaning component and the membrane wall can be reduced by adjusting the cleaning component to fit more closely to the membrane wall, so that the dust that is relatively firmly attached to the membrane wall can be cleaned, thereby improving the cleaning effect. The membrane walls inside boilers of different specifications will also be different. The above-mentioned cleaning device is difficult to adjust, and it is not easy to clean the membrane walls inside boilers of different specifications, which affects the cleaning efficiency.
