Specific implementation mode
Shown in Fig. 1, the regenerative system of this negative pressure benzene removal washing oil includes that regenerator 4, Heat-conduction oil circulation system and washing oil follow
Loop system.It is internally provided with spiral helicine conduction oil coil pipe 5 in regenerator 4, the import of conduction oil coil pipe 5 is under regenerator 4
Portion is stretched out, and the outlet of conduction oil coil pipe 5 is stretched out at the middle part of regenerator 4 or top；The outlet of conduction oil coil pipe 5 is connected by pipeline
It is connected with gs-oil separator 6, the oil discharge outlet pipeline connection heat conduction oil circulating pump 2 of gs-oil separator 6,2 pipeline of heat conduction oil circulating pump connects
Admittance hot oil 3, the import of 3 pipeline connection conduction oil coil pipe 5 of hotline heater.In this way, 5 → oil gas of conduction oil coil pipe
3 → conduction oil coil pipe of separator 6 → heat conduction oil circulating pump, 2 → hotline heater 5 forms Heat-conduction oil circulation system；In heat conduction
Control valve, flowmeter, pressure gauge, thermometer etc. are equipped on the pipeline of oil circulating system as needed.The gs-oil separator
Exhaust outlet has ammonia still process conduction oil head tank 7 by pipeline connection.The lower part of the hotline heater 3 is equipped with blow valve, described
Blow valve pipeline connection has ammonia still process conduction oil underground tank 8.The hotline heater 3 uses electrical heating, and is controlled by PLC temperature
System 1 is controlled.
Shown in Fig. 1, the bottom of regenerator described in the regenerative system of this negative pressure benzene removal washing oil is exported equipped with circulating washing oil, on
Portion is equipped with circulating washing oil import；It is real by pipeline and washing oil circulating pump 9 between the circulating washing oil outlet and circulating washing oil import
Now it is connected to.In this way, circulating washing oil outlet → 9 → circulating washing oil of washing oil circulating pump import → circulating washing oil outlet, forms washing oil and follows
Loop system.It is additionally provided with pressure gauge and flowmeter on pipeline between the washing oil circulating pump 9 and circulating washing oil import.
The use process of the regenerative system of this negative pressure benzene removal washing oil is：When needing the washing oil heating to being recycled in regenerator 4,
