Specifications
1.include the first long pipe evaporator, the second long pipe evaporator, and the strippng tower2.evaporating mix oil
The layered stripping tower developed by our company completely remove the gas shortcut cases, with reliable characteristics, good stripping effect, use flange to connect among the tower trays, maintain and cleanse conveniently.
Flexibly adjust equipment treatment amount can be achieved by increase or reduce number of tray units.
main structure and working theory
1.Equipment structure: this device is composed of several independent parts connected by flange. There is indirect steam heating preserve coat outside shell body. There are 6-11 units trays installed in tower, tray welding to shell body avoid gas shortcut cases, each unit tray is composed of overflow tray, cone-shaped distribute tray and ring supporting tray. Set up liquid foam collect device at the tower top, and oil collect tray at the bottom, it is connected to central pipe through guide flow pipe, and the lower part of the central pipe is connected to indirect steam pipe equipped with nozzle.
2.Working theory: during working, thick mix oil take in from the tower top inlet pipe, first loading the overflow tray of the first unit tray, the overflowed thick mix oil shape very thin liquid certain flowing down at the surface of cone-shaped tray. After adapted by ring tray, still take on liquid film flow to the overflow tray of the second unit tray, again overflow to shape film flow from up to down. The mix gas combined direct steam and solvent is going upward, contact with the converse flowing liquid film layer by layer, so as to dripping out the solvent of the mix oil.
