The invention discloses a water quality control device and method for preventing an indirect air cooling circulating water system from being corroded. The control device is arranged on a bypass of a circulating water pipeline between a condenser and an indirect cooling tower. The control device is provided with a gas absorption tank water inlet pipe, a gas absorption tank, a gas absorption tank water outlet pipe, a compressed gas cylinder, a gas cylinder gas outlet pipe, a pipeline mixer and a pH value online detection device, and the invention further discloses a control method of the device.The device is simple and easy to operate, and the method can adjust the pH value of the water quality in real time, stabilize the water quality for a long time, and effectively prevent the corrosionof carbon steel and pure aluminum in the circulating water system. 本发明公开了一种防止间接空冷循环水系统腐蚀的水质控制装置及方法，该控制装置设置于凝汽器与间冷塔之间循环水管道的旁路上；控制装置设置气体吸收罐进水管、气体吸收罐、气体吸收罐出水管、压缩气瓶、气瓶出气管、管道混合器及pH值在线检测装置；本发明还公开了该装置的控制方法；本发明装置简单，易操作；该方法可实时调整水质pH值，且
