The difference between metal wire mesh corrugated packing and orifice plate corrugated packing

In view of the several layouts of corrugated wire mesh packing, the following features are constituted:


1. Larger than the external surface area, high porosity and light weight. The specific surface area of the 500-type packing is equivalent to 4.5 times that of the metal Pall ring packing (the Pall ring has a specific surface area of 110m2/m3, density: 650kg/square) and the density is only 40% of the Pall ring, and the porosity is high. , The screen has a strong capillary effect to make it have a good wet function, even if the spray density is 0.2, it can reach complete moisture, so the filler power is high.


2. The inclination angle of the gas passage is small, and the gas passage has a regular structure, which reduces the pressure loss and reduces the packing pressure.

3. The radial dispersion is good and the gas and liquid touch are abundant.


4. Avoid blocking, fear of corrosion, difficult cleaning, only chemical cleaning.


5. The high cost of unit volume packing makes its use range subject to certain constraints.


Function comparison of metal wire mesh corrugated packing and metal plate corrugated packing: The most significant difference between metal wire mesh corrugated packing and metal plate corrugated packing is that the mass transfer power of wire mesh corrugated packing changes greatly with load in the operating range. The separation power of metal plate corrugated packing is almost unaffected by load changes. This is because the surface of the wire mesh has a capillary effect, and even a small amount of liquid can be spread evenly on the surface of the wire mesh even at low liquid phase loads, so the power of the filler increases under low loads.
