Problems solved by technology

During the detection process, the metal probe of the detector needs to be directly exposed to the gas medium, so the container containing the gas medium needs to be damaged and then installed. Due to problems such as the aging of the UV emitter, it is necessary to perform regular calibration operations on the leakage state spectrum of the ultraviolet emitter, which will cause blind spots in the detection during the continuous operation of the power plant; the analysis control module only provides standard interfaces, and it can only be used after software customization

Abstract

A photo-thermal power generation heat transfer and storage medium leakage detection system provided by the present invention comprises a tank body, a first pre-processing device, a gas chromatographic analyzer, a second pre-processing device, an infrared gas analyzer and an analysis monitoring module. The tank body is equipped with at least one air pressure balance valve, the first pre-processing device is used to pre-process a gas medium discharged by the air pressure balance valve and divides the pre-processed gas medium into two to send to the gas chromatographic analyzer and the infrared gas analyzer respectively, and the analysis monitoring module obtains the data detected by the gas chromatographic analyzer and the infrared gas analyzer, and displays, records and analyzes the detection data. According to the present invention, the tank body and a detection device are connected together in a detachable manner, thereby avoiding the direct damage to the tank body, reducing the fault links, and improving the maneuverability of the detection system.

Description

technical field [0001] The invention relates to the technical field of gas leakage detection, in particular to a system and method for detecting leakage of a photothermal power generation heat storage heat transfer medium. Background technique [0002] The solar trough concentrating power plant is composed of three parts: the trough reflector field part, the heat transfer heat storage part and the thermal power plant. The trough mirror field is responsible for tracking the sun and focusing the heat on the heat collecting pipe. The heat on the heat collecting pipe will exchange heat energy to the thermal power plant through the heat transfer part (HTF). If enough heat energy is collected, it will be transferred to the heat storage system. (TES) for storage and backup, and finally reaches the thermal power plant to generate high-temperature and high-pressure steam to drive the steam turbine to generate electricity. [0003] The heat transfer part is a pressure circuit, and it...
