Rising film Evaporator
Material: carbon steel shell, stainless steel or aluminum alloy tube
Application:
The evaporator is usually used for separation between oil and solvent and purification of miscella concentration so as to reach technical requirements in oil,chemical and other fields.
The evaporator has features of simple operation , fluid is filminess when evaporating, small hydraulic resistance, good heat transfer effect,short retention time of miscella, quick evaporation velocity,it can heat miscella from about 400ºC to 1100-1500ºC in shorter time,so it has less impact on the quality of miscella.
Working principle
The working principle of long tube evaporator is according to big boiling point difference between oil and solvent in miscella,separate solvent from dilute miscella of 40-60ºC, 10-30% by means of indirect steam among shell pass,and concentration of oil will be higher up to meeting the technical requirements.
Evaporation Process
Miscella enters the first long tube evaporator tube pass from miscella tank, evaporated solvent enters evaporation condenser through separation chamber,outlet pipelines of separation chamber set liquid level control device to keep liquid seal. Miscella enters disc of tower from the top of steam-stripping tower,fall layer by layer,at the same time inject direct steam from the bottom,remove residual solvent.Top outlet connects evaporation condenser, use high vacuum injection pump to keep steam-stripping tower work under negative pressure, equipped with liquid level controller on the bottom of steam-stripping tower to ensure liquid level and stable flow of finished oil,
crude oil is drawn from tower bottom with steam-stripping drawn pump to cool and then enters crude oil tank.
★ Evaporation temperature is low, residual solvent in crude oil is low, color is light,no phospholipids precipitation,evaporator and steam-stripping tower scaling not easy;
★ The advantages of using long tube condenser is high solvent recovery rate,reducing condenser area and saving investment cost.
★ Using boiling tank makes solvent in drained waste water reach the minimum value.
