Embodiment Construction

[0065] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0066] see figure 1 As shown, the embodiment of the present invention provides a detection device for gas-liquid two-phase distribution field and temperature field distribution in a boiler, including: a plurality of liquid ultrasonic transducers 1 and gas ultrasonic transducers arranged on the inner tube wall of the boiler 2. At least part of the liquid ultrasonic transducer 1 and the gas ultrasonic transducer 2 are arranged alternately, and the liquid ultrasonic transducer 1 and the gas ultrasonic transducer 2 are located on the same plane, which passes through the center point of the boiler. When the plane where the liquid ultrasonic transducer 1 and the gas ultrasonic transducer 2 are located passes through the central point of the boiler, the detection plane is the largest, which can best reflect the gas-liquid two-phase distribution field...

Abstract

Relating to the field of ultrasonic imaging, the invention discloses a detection device for gas-liquid phase distribution field in a boiler. The detection device includes a plurality of liquid ultrasonic transducers and gas ultrasonic transducers arranged on a boiler inner tube wall, at least parts of the liquid ultrasonic transducers and the gas ultrasonic transducers are arranged alternately, and the liquid ultrasonic transducers and the gas ultrasonic transducers are located on a same plane. The detection device for the gas-liquid phase distribution field in a boiler provided by the invention can detect the gas-liquid phase distribution field in the boiler by ultrasonic imaging method, has large measuring scale and wide application scope.

Description

technical field [0001] The invention relates to the field of ultrasonic imaging, in particular to a detection device and a detection method for a gas-liquid two-phase distribution field in a boiler. Background technique [0002] The gas-liquid two-phase distribution field and temperature field in the boiler directly affect the safety of the boiler, so it is particularly important to detect the gas-liquid two-phase distribution field and temperature field in the boiler. Existing capacitance tomography, electrical resistance tomography and other two-phase field measurement technologies use sensors to detect the distribution of resistance and capacitance in the boiler to obtain the gas-liquid two-phase distribution field. [0003] However, the above method is only applicable to boilers with non-conductive tube walls, and the conduction of the tube walls will affect the detected resistance and capacitance, which cannot be detected by sensors. Contents of the invention [0004...
