Wherein, 1, heat-exchanger rig；2nd, rectifying column；3rd, heater；4th, condenser.
Specific embodiment
Presently preferred embodiments of the present invention is described in detail below in conjunction with the accompanying drawings, so that advantages and features of the invention energy
It is easier to be understood by the person skilled in the art, apparent is clearly defined so as to be made to protection scope of the present invention.
Fig. 1 show of the invention one and uses dichloromethane extract separator, specially a kind of also paraffin oil
The rectifier unit of dichloromethane extract.
With reference to shown in Fig. 1, a kind of dichloromethane extract separator, including rectifying column 2, for heating dichloromethane
Heater 3 with paraffin oil mixed liquor, the condenser 4 for being condensed to dichloromethane steam.The rectifier unit is also wrapped
Include heat-exchanger rig 1.
The heat-exchanger rig 1 is tubular heat exchanger, and the heat-exchanger rig 1 has interconnected the first air inlet and first
Gas outlet, interconnected the first inlet and the first liquid outlet.The air inlet passes through pipeline with the tower top of the rectifying column 2
It is connected, the gas outlet is connected with the condenser 4 by pipeline, feeding liquid is caused the heat exchanger by the inlet
In, the liquid outlet is connected with the charging aperture of the rectifying column 2 by pipeline.The heat-exchanger rig 1 also has the first condensation
Liquid is exported.
The rectifying column 2 has and is opened in the second liquid outlet of bottom and is opened in the second inlet of bottom, and described the
Two liquid outlets are less than second inlet, and the heater 3 is connected with second liquid outlet and the second inlet respectively
It is logical.The heater 3 has paraffin oil export, and dichloromethane and paraffin oil mixed liquor are by second liquid outlet from the essence
The bottom of tower 2 into the heater 3 is evaporated, dichloromethane steam enters institute by second inlet from the heater 3
State rectifying column 2.
The heater 3 is heat-conducting oil furnace.
The condenser 4 has the second air inlet and the second condensate outlet, and second air inlet and described first goes out
Gas port is connected.Reduction of fractions to a common denominator pipeline is pooled in main pipe rail respectively for first condensate outlet and the second condensate outlet.
The course of work of rectifier unit of the invention is as follows：The dichloromethane steam of the tower top of rectifying column 2 is introduced to heat exchange
As hot fluid in device 1, to feeding liquid（It is mixed with the dichloromethane extract of paraffin oil）Preheated, the feeding liquid after preheating
Enter into rectifying column 2, meanwhile, feeding liquid is cooled down as cold fluid to dichloromethane steam again, and part methylene chloride steams
