Description

Used for absorbing, condensing, distilling, evaporating, filtering and washing the organic products, as hydrochloric acid, sulfuric acid, and other corrosive mediums Three types: Packed tower Bubble tray column Sieve plate tower Diameter can be from **0 to 2, **0mm Customized drawings and designs are welcome Can do it by impermeable graphite (impregnated) or by teflon Following introduction are on basis of impermeable graphite: Graphite packed tower: Composed of perforated plates, packing, and showering devices Ascending gas transfers heat to the packing it contacts with and the packing are cooled by liquid shower Graphite packing tower is suitable for gas absorption or washing. Tower plate number is customizable Bubble tray column: Foaming plate type tower Gas or steam through the cap on the tray comes into contact with the liquid on the plate in dispersing method Structure is complicated Consists of column body, bubble cap, overfall dam, falling liquid tube, and the bubble cap is the most important part Sieve plate tower also called plate tower Many small holes are drilled on the plate inside the tower When the gas comes through the holes, the liquid on the plate foams by the gas, this means the gas comes into contact with the liquid in more area This type is a simple structure, easily produced, and lower cost than bubble tray column Its treated quantitatively and effective is better than bubble tray column But it is not fitful for the situation when the gas and liquid is on loading Small holes will be easily blocked this is its disadvantage Can also supply the above towers in teflon material in stead of graphit
