Abstract

The invention discloses a device and a method for testing the water permeability of a planar filter medium for liquid and solid separation. The device mainly comprises a support baseplate, a baseplate support leg, a support pole, a water outlet, a lower connecting flange, a sealing ring, a supporting screen, a filtering element mounting plate, a fastening clamp, an upper connecting flange, a barrel, a water inlet, a water inlet sealing socket, an exhausting and pressurizing port, an incoming water distribution plate, an overflow port positioning rod, an overflow water outlet ring, an overflow outlet pipe, an overflow port sealing socket, an overflow adjusting pipe, an overflow port elbow, a liquid level meter and the like. Due to the adoption of the test device and the method of the invention, the water permeability of the planar filter medium can be tested correctly and rapidly under a vacuum or pressurized condition and basis for scientific evaluation, selection and use of the filter medium is provided.

Description

technical field [0001] The invention relates to a device and method for testing the performance of a filter medium in the technical field of liquid-solid separation, in particular to a test device and a method for testing the water permeability of a planar filter medium. Background technique [0002] In the liquid-solid separation process, the filter medium is the core component in the unit operation, and its performance will directly affect the separation effect. There are many performance indicators of the filter medium, among which the water permeability is an important performance indicator for the selection and use of the filter medium. It is measured by the water permeability rate and the water permeability resistance. The water permeability rate is the amount of pure water passing through the filter medium per unit area vertically per unit time. The water permeability resistance is the resistance suffered by pure water passing through the filter medium per unit area v...
