Description

Technical Field

[0001] The utility model relates to the technical field of thermal power generation condenser cleaning, in particular to a cold end energy-saving and optimized thermal power generation condenser cleaning machine. Background Art

[0002] The condenser is a key heat exchange equipment in a thermal power plant. During the heat exchange process, the temperature difference between the inside and outside of the condenser tube is very large, and thick scale is easily formed inside the tube. These scales are composed of biological slime, mud, a large amount of salt precipitated from calcium and magnesium, or impurities contained in the water. Scaling will have a serious impact on the heat exchange efficiency of the condenser and will also cause corrosion of the condenser tube.

[0003] The utility model with the existing authorization announcement number CN219494990U discloses a condenser descaling device for a power plant, including a high-pressure cleaning machine, a high-pressure hose, a high-pressure cleaning machine working pedal and a nozzle, one end of the high-pressure hose is connected to the inlet water pipe interface of the high-pressure cleaning machine, and the other end is connected to the nozzle, the nozzle includes a high-pressure water inlet flow channel and a high-pressure water outlet flow channel, and the inlet flow channel and the outlet flow channel are in opposite directions; the high-pressure cleaning machine working pedal is used to control the working state of the high-pressure cleaning machine, that is, stepping on the high-pressure cleaning machine working pedal pressurizes the cleaning water, and no pressurization occurs after releasing it; the outer diameters of the high-pressure hose and the nozzle are both smaller than the interlayer spacing of the cooling water pipes of the condenser to facilitate the nozzle to move between layers for cleaning.

[0004] By adopting the above technical scheme, the nozzle automatically moves from the front tube sheet to the rear tube sheet of the condenser under the action of the water flow. When the nozzle moves to the rear tube sheet, the cleaning worker pulls the nozzle from the rear tube sheet to the front tube sheet, which effectively improves the speed of cleaning the condenser cooling tube and improves work efficiency. However, the above technical scheme only cleans the condenser with high-pressure water when cleaning the condenser, and cannot soften the scale in the condenser, thereby failing to clean the strongly adherent dirt, resulting in poor dirt cleaning effect and low practicality.

[0005] Therefore, those skilled in the art provide a cold-end energy-saving and optimized thermal power generation condenser cleaning machine to solve the problems raised in the above-mentioned background technology. Utility Model Content
