Leakage detection device and detection method using same

Abstract

The invention discloses a leakage detection device. The device comprises a liquidometer, a data collecting and monitoring control device and control equipment. According to the leakage detection device, an absolute value of an actual relative liquid level change rate is compared with an absolute value of a standard relative liquid level change rate to judge whether large leakage occurs, and then an alarm is given. Therefore, the false alarm of the leakage detector in the prior art is eliminated, the system stability is increased, and a large amount of leakage can be relatively accurately monitored. Meanwhile, the invention further provides a method for detecting waste water leakage. In the method, a measuring value of the liquidometer is collected through the data collecting and monitoring control device; and meanwhile, the actual relative liquid level change rate of a barrel tank is calculated by using the control equipment, and the absolute value of the actual relative liquid level change rate is compared with the absolute value of the standard relative liquid level change rate to judge whether the large leakage occurs, and then the alarm is given. The method is simple and reliable.

Description

technical field [0001] The invention relates to the technical field of leak detection, in particular to a leak detection device and a detection method. Background technique [0002] Semiconductor chip manufacturing is a cutting-edge technology industry, but it is also an industry that consumes a lot of water and produces a lot of industrial wastewater. The sources of wastewater in semiconductor chip manufacturing plants can be roughly divided into chemical wastewater, pure water system wastewater, and process wastewater. [0003] The waste water is generally collected and treated through the waste water lifting station. The waste water lifting station is the area where the factory collects various production and drainage in the clean room, and is generally located in the basement or semi-basement. Dozens of collection tanks for different types of chemicals, waste water and waste liquid are arranged in the waste water lifting station, and the collection tanks are used to col...
