Abstract

The invention discloses a tubular porous element pure water flux testing device which comprises a clamp used for clamping a tubular porous element, the inlet end of the tubular porous element is connected with a water storage pond through a water inlet pipeline, a pressurizing part is arranged on the water inlet pipeline, and a pressure gauge is arranged at the inlet end of the tubular porous element, and a water collecting tank is arranged below the clamp. According to the testing device, the fixture for clamping the tubular porous element is arranged, so that the whole tubular porous element completely participates in the testing process, the stability of the testing process is ensured, the permeation working process of the tubular porous element under the actual working condition is effectively simulated, the accuracy of a pure water flux result obtained through testing is improved, the problem that an existing testing method and an existing testing device need to damage the tubular porous element is solved, and the testing device is simple in structure, convenient to carry, capable of meeting the testing requirement for the tubular porous element under the outdoor engineering condition and wide in application range.

Description

technical field [0001] The invention belongs to the technical field of porous material testing, and in particular relates to a testing device for pure water flux of a tubular porous element. Background technique [0002] Due to the characteristics of highly connected three-dimensional pore structure, high specific surface area, and low density, porous materials are indispensable in the process links such as filtration separation, fluidization distribution control, and thermal management in the nuclear industry, chemical machinery, and aerospace and other modern industrial fields. substitute role. [0003] Using powder particles as raw materials, the tubular porous element produced by pressing-sintering-processing has the advantages of large specific surface area, good assembly performance and high replaceability, and has become the main structural form of porous elements in the filtration and separation industry. Among the many functional properties of porous materials, per...
