Filter system 7, regeneration by-passing valve 12, filtration system 2, oily on-line monitoring system 3 and fuel reserve tank 11, to oil circulation heating and mistake
Impurity is filtered, the real-time oily state s of monitoring is recordedp(cp, wp, vp)；
10) with the progress of filter process, oil liquid is constantly reduced in the vacuum tank of vacuum dewatering system 1, in fuel reserve tank 11
Oil liquid is continuously increased, and when capacity of the oil liquid in vacuum tank lower than setting, then the oily motor-driven valve that falls for controlling fuel reserve tank 11 is opened,
Oil storage tank oil liquid is sucked by negative pressure of vacuum, when capacity of the oil liquid of oil storage tank lower than setting, then controls oily motor-driven valve
It closes；
11) step 9)~step 10) is repeated；
12) oily on-line monitoring system 3 judges the oil of oil liquid according to oil liquid granularity, moisture and the viscosity index of monitoring
State, as real-time oily state sp(cp, wp, vp) better than default acceptance value when, and when in vacuum tank oil liquid lower than setting capacity
When, stop oil circulating pump 9, oil liquid is in the oil storage tank of fuel reserve tank 11 at this time；
13) it is filling will to handle qualified oil liquid progress oil drum for cleaning bulking system 5 in fuel reserve tank 11；
Filling oil mass need to be set according to oil drum when filling, when starting filling, open the filling motor-driven valve of bulking system 5, when
When filling oil mass is greater than setting filling oil mass, then the filling motor-driven valve of bulking system 5 is closed.
