Title:
THREE-DIMENSIONAL ELECTRICAL CAPACITANCE VOLUME TOMOGRAPHY DEVICE FOR LOW TEMPERATURE FLUID FLOW IN VENTURI TUBE
Document Type and Number:
WIPO Patent Application WO/2021/218490
Kind Code:
A1
Abstract:
A three-dimensional electrical capacitance volume tomography device applied to deep low temperature fluid flow monitoring in a Venturi tube, comprising: a conductor rod (1), a metal housing (2), a Venturi tube (3), electrode sheet sleeves (4), electrode sheets (5), and an annular connection housing (6). According to the device, the electrode sheets (5) and the electrode sheet sleeves (4) are attached to the surface of the Venturi tube according to the variable-diameter characteristic of the Venturi tube (3), and a corresponding wire connection structure is designed, and a shielding housing is designed according to the characteristic that electrical capacitance volume tomography needs to be shielded. The device has the features of simple and stable structure, simple assembly and disassembly, being able to be assembled and disassembled many times, being able to be quickly connected to other pipelines, being able to be used in a large range from room temperature to deep low temperature, and having a good electromagnetic shielding effect.
