Product Description

The guide sieve plate is improved based on the ordinary sieve plate tower. Its structure characteristics is: on the tray to open a certain amount of pilot hole, through the direction of air flow and liquid flow guide hole, have a certain role of fluid flow, to reduce surface gradient; Added on the liquid into the hole in plate bubbling promote structure, is advantageous to the liquid just into the plate can produce bubble, form good gas-liquid contact conditions, in order to improve the utilization rate of plate, thinning fluid layer, reduce the pressure drop. Compared with ordinary sieve plate tower, the plate efficiency can be increased by about 13%, and the pressure drop can be about 15%.

The shape of the guide hole is like a shutter, similar to that of the tongue, but the opening is a long, thin rectangle. Seam length has 12mm, 24mm, 36mm 3 kinds. The height of the guide hole opening is usually 1-3mm. The orifice of the orifice is generally 10 to 20 percent. The bubbler stimulator is a raised part formed at the entrance of the plate. The raised height is generally 3-5mm, the inclined plane is usually between 0.1 and 0.3, and the inclined plane usually only has the sieve hole and not the guide hole.
