The process of preparing nanometer capsule phase change material emulsion includes adding the oil phase liquid compounded with olefin monomer, hydrophilic monomer, alkane, initiator and n-lauryl mercaptan into the mixed liquid of emulsifier and deionized water via stirring and ultrasonic dispersing to obtain micro emulsion, introducing nitrogen to the micro emulsion system to eliminate oxygen viastirring, reflux condensing, heating to 65 deg.c and constant temperature polymerization reaction for 5 hr, and cooling naturally to room temperature to obtain the nanometer capsule phase change material emulsion. Thus prepared nanometer capsule phase change material emulsion has nanometer size, stable performance, great phase change enthalpy and wide application in latent heat functional hot fluid, heat accumulating and temperature regulating fabric, energy saving building wall and other fields.

The invention discloses a static mixed flow separating screen for a spiral-wound membrane. The screen is composed of a plurality of separating screen strips which are fixed through a separating screen strip frame and uniformly distributed in the feeding direction at equal intervals. Each separating screen strip is composed of a plurality of separating screen units. Each separating screen unit is provided with three fluid channels perpendicular to the fluid inlet direction. Fluid carries out static flow mixing in the separating screen units and does not generate vortexes or turbulence, and fluid dead space does not exist when the fluid flows through the separating screen. According to the static mixed flow separating screen for the spiral-wound membrane, the fluid close to the surface of the membrane and the fluid in the centers of the fluid channels can be transferred mutually, the mechanical condition of the fluid on the surface of the membrane is changed, the vortexes and the turbulence are avoided, the separating screen is different from various existing schemes, the surface concentration of materials held back by the membrane is reduced, the mass transfer rate is increased, and fluid mixing is strengthened; moreover, pressure drop and pump consumption increased in the operating process of the membrane due to adding of the separating screen are reduced while concentration polarization and membrane pollution are effectively reduced, and the energy utilization ratio is increased.
