Prior art processes for producing protein-based capsules (for example, capsules for use in electrophoretic media) tend to be wasteful because they produce many capsules outside the desired size range, which is typically about 20 to 50 μm. Capsule size distribution and yields can be improved by either (a) emulsifying a water-immiscible phase in a preformed coacervate of the protein; or (b) using a limited coalescence process with colloidal alumina as the surface-active particulate material.

The invention relates to a device used for removing absorbable granules PM2.5 based on acoustic wave and with the addition of associative action of seed granules and a method thereof, in particular to a set of devices used for removing the absorbable granules (hereinafter called PM2.5 for short) with grain diameter less than 2.5 micrometers in dusty gas and a method thereof. The device comprises a sound source, an acoustic agglomeration chamber, a feedway for the seed granules, subsequent normal dedusting equipment, etc. When flue gas discharged by various combustion sources or other dusty gas flows through the acoustic agglomeration chamber, fine granules in airflow arise entrainment of different degrees under the action of the acoustic wave, while the added seed granules nearly do not arise entrainment due to relatively large inertia thereof; meanwhile, the fine granules and the seed granules are different in gravity settling and acoustic drift. The three reasons lead to relative movement between the fine granules and the seed granules, thus generating quite high collision rate between the absorbable granules PM2.5 and the seed granules. After the absorbable granules PM2.5 collide with the seed granules, agglomeration happens between the absorbable granules PM2.5 collide with the seed granules; coacervate generated by the agglomeration is further removed by the subsequent normal dedusting equipment.
