Mesh sieve plate area also has specialization, each a product is feeling usage design suitable for the structure. We use like stainless steel mesh, screen mesh, polyurethane sieve plate belongs to general can sieve plate, the common mesh sieve plate with conical sieve plate is a very different nature. Ordinary sieve plate and conical sieve plate in different superficial gas velocity on the dry plate pressure drop compared to line we can see that if the length to diameter of taper sieve plate and ordinary sieve plate at the same aperture, and the short diameter smaller than ordinary sieve plate hole, so both on the conical sieve plate and the conical sieve plate, dry plate pressure drop is bigger than ordinary sieve plate, and the greater the gas velocity, the greater the difference between the dry plate pressure drop.
