Example Embodiment
[0031] The technical solution of the present invention will be further described by specific embodiments in conjunction with the accompanying drawings.
[0032] Such as figure 1 As shown, a device for an online test method for the cleaning rate of a tube heat exchanger includes a reagent tank 3 on which a stirrer 13 for stirring reagents and a level device 11 for observing the internal water level are installed , There is also a PH tester Ⅱ16 for detecting the pH of the reagent. The lower part of the reagent tank 3 is connected to a liquid injection pump 4, and the liquid injection pump 4 is connected to a corrosion box 15 with a corrosion tube inside. The corrosion box 15 is connected to a liquid injection valve 14 for liquid injection. The pump 4 injects the reagent in the reagent tank 3 into the heat exchange tube 19 through the cleaning nozzle 2 on the positioning device 1 in the condenser 18. The reagent drives off the cooling water in the heat exchange tube 19, and when the...
