| Summary: | A theoretical analysis of colmatation regularities pertaining to high disperse particles from gas streams in various porous materials has been carried out in the paper. The paper reveals that under usual conditions the colmatation efficiency of high disperse particles having diameter 0.5 microns and less basically depends on a stream velocity and size of filter fibers that is higher velocity and larger fiber diameter entail lower colmatation efficiency. An increase in density of filter material packing makes insignificant impact on the rate of particles catching but leads to growth of resistance and correspondingly to reduction of the filter productivity. A joint action of diffusion mechanisms, a contact, and partially inertia is observed at high stream velocities. |
