Due to the high strength of the metal mesh packing, it is widely used. The metal mesh packing is cut into a certain shape from a wire mesh and then bound. Among them, the burrs left during cutting or the rust falling off the wire easily fall on the distributor provided in the rectification tower along with the part of the liquid output from the condenser, which will block the holes on the distributor for a long time. It will further affect the gas-liquid two-phase contact, which in turn affects the distillation efficiency.

The inclination, and in turn, can make the filter plate at different inclination angles according to the use situation, so that the sundries fall into the arc-shaped groove under the action of its own gravity and the impact of oil, thereby increasing the filtering effect of the filter plate and improving The separation effect of impurities and petroleum prevents impurities from clogging the distributor, thereby improving the distillation efficiency of petroleum.
