Detecting assemble for film products

Abstract

A membrane product testing module is composed of protecting plate with central window, upper plate made of transparent high-molecular material and with liquid channel on its bottom surface, lower plate with flow guide slot communicated to the liquid outlet, base, and the milli-pore plate and sealing ring between said upper and lower plate. Its advantages are high visuality, low cost and high efficiency.

Description

technical field [0001] The invention relates to a membrane product detection component, specifically a membrane product detection component that mainly detects the quality of the liquid separation membrane and the membrane process, and the main classification number of the international patent is intended to be Int.Cl 7 .B01D 13 / 00. Background technique [0002] Various pressure-driven membrane processes can be used for the concentration or purification of dilute (aqueous or non-aqueous) solutions. The size and chemical properties of the solute particles or molecules in the liquid determine the structure of the required membrane, that is, the pore size and pore size distribution. Microfiltration and ultrafiltration membranes are mainly used to intercept particles, bacteria and macromolecules from the liquid phase to achieve purification, separation and concentration. Nanofiltration and reverse osmosis membranes are mainly used for water softening. Regardless of the purpos...

Problems solved by technology

Their main disadvantages are also that they cannot approximate the hydrodynamic performance of the membrane under actual operation. At the same time, these capsule components are not sufficiently sealed, easy to leak, and have high manufacturing and use costs.

In addition, the above-mentioned membrane detection assembly also has the disadvantages of time-consuming and low efficiency in the process of replacing the membrane.

[0005] Although the Sepa CF I and II square flat membrane detection components produced by GE Osmonics (GE Osmonics) can solve many of the shortcomings of the circular flat membrane components and membrane box components, they can be approximated during the performance test of the membrane. Simulate the hydrodynamic performance of the membrane under actual operation, but these square flat membrane detection components are difficult to observe with the naked eye the installation of the membrane sample and the operation process due to its fixed plate (top cover) is a fully sealed thick plate. At the same time, these square flat-panel membrane detection components cannot provide effective observation points, nor can they perform non-destructive measurements on the operating status or process of the membrane (such as pollution, cleaning, etc.) Technology) on-line monitoring, it is difficult to improve the quality of detection and in-depth research on the membrane process

In addition, as test instruments or test devices, these square flat membrane detection components are very heavy (about 30 kg), inconvenient to carry and use, and the cost is relatively high, which is unfavorable for popularization and use.
