Description

Technical Field

[0001] The invention relates to the technical field of waste heat recovery, and in particular to a water leakage detection device for waste heat recovery of a kiln. Background Art

[0002] The kiln waste heat recovery device works on the principle of heat exchange. The waste heat generated by its operation is led to the heat exchanger through the pipeline along with the exhaust gas, and the heat is transferred to the air. The heated air can be dried or returned to the kiln to assist combustion, thereby improving thermal efficiency.

[0003] When there is water leakage at the connection of the kiln waste heat recovery device, if the connection parts are made of metal, water will react chemically with the metal, gradually corroding the metal and weakening the connection structure, which may cause the connection parts to rupture or be damaged, further affecting the normal operation of the waste heat recovery device. If it is not resolved in time, it will further increase the scope and cost of maintenance. Summary of the invention

[0028] Specifically, when the kiln waste heat recovery device 1 leaks, the driving motor 902 starts to drive the driving gear 903 to rotate.

[0029] Working principle: When the kiln waste heat recovery device 1 is running, the heat is discharged through the output pipe 4, and the conical recovery port 7 at the front end collects the waste heat and transfers it to the waste heat recovery pipeline 10 through the input pipe 6. If there is a leak at the connection between the input pipe 6 and the waste heat recovery pipeline 10, water will drip at the connection between the input pipe 6 and the waste heat recovery pipeline 10. The leakage pipe 13 collects the water flowing down from the bottom of the protective shell 8. If the leakage increases, the water pressure will push the telescopic detection needle 1417 to compress downward, and the pointer 1412 will move in front of the scale plate 1414. The leakage detector 1418 can detect the leakage and the leakage amount through the displacement position of the telescopic detection needle 1417 and the pointer 1412. An alarm is sounded in the control center to remind the staff of the water leakage. At the same time, the scraper 911 first scrapes off the larger water droplets, and then the cleaning roller 913 rolls under the support of the U-shaped round rod 912 to further clean the remaining water stains. The two work together under the drive of the symmetrical connecting frame 909 to carry out emergency treatment of the leakage at the connection between the input pipe 6 and the waste heat recovery pipe 10, waiting for the staff to arrive for treatment. During the whole process, the leakage detection component 14 monitors the leakage in real time, and the leakage treatment component 9 cleans the water stains in time to ensure the stable operation of the kiln waste heat recovery device 1. Finally, the water collected at the bottom of the leakage pipe 13 flows into the water collecting tank 16 for storage.
