Different structure dewaxing device

The utility model discloses a different structure dewaxing device belongs to the lube oil base stock production field. Different structure dewaxing device is still including cold low oil heater of branch and the low oil heater that divides of heat. The utility model discloses a cold low oil heater of branch sets up between cold low separator and fractionating tower, heat the low oil that divides of the cold of isolating through the cold low separator through the cold low oil heater of branch, heat the low oil heater of branch set up between heat low separator and fractionating tower, heat the low oil that divides of heat that the menstruation heat low pressure separator was isolated through the low oil heater of branch of heat, thereby make low oil and the cold low oil content that divides of dividing of heat do not heat, avoid dividing the oily and cold low oily heat transfer that mixes low branch oil of influence heat and cold low branch oil that divides because of heat is low, thereby reduce low oil and the cold low energy consumption of dividing oil of dividing of heating heat.
