Description

Technical Field

[0001] The utility model relates to the technical field of boilers, in particular to a boiler cleaning device. Background Art

[0002] A boiler is a common energy conversion device. After long-term use, scale will form on the inner wall of the boiler. When the boiler is scaled, the temperature of the heating surface will increase. If the boiler heating surface operates at ultra-high temperature for a long time, the metal material will creep, bulge, and reduce strength, leading to pipe bursts, endangering people's lives. After the boiler is scaled, the heat exchange efficiency is low, so the boiler needs to be cleaned regularly to prevent accidents.

[0003] Existing boiler cleaning generally adopts manual cleaning. After the boiler is disassembled, cleaning agents are poured in and manually wiped and cleaned. The cleaning efficiency is low and the dirt cannot be completely cleaned. In addition, the cleaning agents used for cleaning are usually chemical agents. During the cleaning process, the cleaning agents will inevitably splash and spill to the outside, causing waste and damaging the environment. For this reason, we design a boiler cleaning device to solve the above technical problems. Utility Model Content
