After cleaning, perform a flux recovery test and compare the recovery amplitude with the baseline. If the recovery amplitude decreases gradually and irreversibly, arrange for replacement. This article explains the testing scope and judgment logic.
2026-11-10The online monitoring of membrane components focuses on the trends of permeate side pressure, flux, and pressure difference, and predicts cleaning and replacement using trend inflection points. This article explains the monitoring items, baseline management, and maintenance logic.
2026-11-09The membrane is afraid of two things: solid particles and liquid water. Dust in the intake will cause film sticking, and water will damage the separation layer. Pre treatment involves using a wire mesh for mist removal and multi-stage precision filtration to remove fog droplets, dust aerosols, and free moisture. Then, temperature and humidity protection membrane components are controlled to ensure long-term stability of the membrane method.
2026-11-08Selection is not about choosing a membrane, but about calculating three accounts based on the medium, gas volume, and concentration: the medium account determines the membrane area and pretreatment, the recovery account determines the upper limit of input, and the operation account determines the annual consumption and lifespan. The key to membrane component management lies in the ledger: recording the date of use, flux trend, cleaning records, and replacement nodes, and using trends instead of years to determine the lifespan.
2026-11-07Installation and debugging are carried out in five steps: acceptance upon arrival, installation of piping, pre-treatment and joint debugging, airtightness and vacuum, and operation with gas; Check the piping to prevent misconnection, perform airtight vacuum leak detection, and gradually increase to the design range starting from low pressure and small load.
2026-11-05Membrane separation and recycling are suitable for high calorific value solvent working conditions such as pharmaceuticals, fine chemicals, industrial coatings, and new energy. They are most suitable for high concentration, high flow rate, and intermittent emissions. This article explains the adaptation boundaries between industries and working conditions.
2026-10-29The flow rate of the activated carbon box is determined according to the form of the adsorbent. The apparent flow rate of granular carbon is 0.4 to 0.6 meters per second, and the carbon layer is around 400 millimeters. This article lists the key configuration points.
2026-10-22The solvent recovery system forms an explosion-proof defense line by online monitoring of oxygen content, nitrogen replacement, and interlocking shutdown. This article explains the alarm settings, replacement standards, and interlocking logic.
2026-10-22The local gas collection hood is designed with a controlled wind speed of no less than 0.3 meters per second, and the air volume is calculated based on the hood mouth area and wind speed. This article explains the key design points of the collection system.
2026-10-22When multiple types of solvents are continuously recovered, the residue from the previous batch will contaminate the next batch. Pre switching blowing and tank classification are two barriers to prevent cross contamination. This article explains the methods used.
