Fig. 1 is a flowchart of embodiment 1 of the present invention.
Detailed Description
The technical solution of the present invention will be further described in detail with reference to the following detailed description, but the present invention is not limited thereto.
Example 1:
as shown in fig. 1, a system for purifying lubricating oil of a combustion engine comprises a lubricating oil tank 1, an oil pump 2, a coalescing separator 3, a pre-filter 4, a water absorption filter 5 and a fine filter 6, wherein the lubricating oil tank 1, the oil pump 2, the pre-filter 4, the coalescing separator 3, the water absorption filter 5, the fine filter 6 and the lubricating oil tank 1 form a circulation system through pipelines; be equipped with in the coalescence separator 3 and gather filter core 7 and separation filter core 8, gather the export of filter core 7 and the entry linkage of separation filter core 8, the export of gathering filter core 7 is connected to the entry of oil pump 2 through first pipeline 10, the export of separation filter core 8 is connected to the entry of oil pump 2 through second pipeline 9, all be equipped with manual valve on first pipeline 10, the second pipeline 9.
The process of treating the lubricating oil by the coalescence separator 3 is as follows: through the processes of filtering, demulsifying, water molecule growing up and coalescing, impurities are trapped in the coalescing filter element 7, coalesced water drops are settled in the precipitation tank, oil enters the separation filter element 8 from outside to inside, and is collected in the secondary tray and flows out from the outlet of the coalescing separator 3. The material of the separation filter element 8 has hydrophobicity, oil can pass through smoothly, and free water is blocked outside the filter element, flows into the precipitation tank and is discharged through the sewage discharge valve.
In this scheme, the normal filtering process is: the lubricating oil tank 1 → the oil pump 2 → the pre-filter 4 → the coalescing separator 3 → the water absorbing filter 5 → the fine filter 6 → the lubricating oil tank 1, and the lubricating oil is subjected to deep filtration and cleaning by continuous circulation filtration.
Because the coalescence separator 3 has certain volume, can hold more lubricating oil, consequently can carry out the reflux to some lubricating oil through first pipeline 10 and second pipeline 9 and handle, if emulsify comparatively seriously in the lubricating oil, then supply certain lubricating oil after the breakdown of emulsion to the oil pump 2 entry through first pipeline 10, second pipeline 9, can reduce the emulsification degree of the lubricating oil of oil pump 2 entry, reduce the processing pressure of coalescence filter core 7.
Preferably, a differential pressure sensor 11 is arranged between the inlet of the coalescing filter element 7 and the outlet of the separation filter element 8. If the pressure difference is too large, the filter cartridge 7 and the separation filter cartridge 8 need to be cleaned.
Preferably, the sewage treatment device further comprises a sewage oil tank 12, and the pre-filter 4, the water absorption filter 5 and the fine filter 6 are all connected to the sewage oil tank 12 through pipelines provided with valves.
In this embodiment, the outlet of the pre-filter 4 and the inlet of the fine filter 6 are connected by a third pipeline 13, a first solenoid valve 14 is arranged on the third pipeline 13, a second solenoid valve 15 is arranged at the inlet of the coalescer 3, and if the coalescer 3 needs to be cleaned, the second solenoid valve 15 can be closed and the first solenoid valve 14 can be fully opened. If the lubricating oil contains little water and no emulsification or water removal is necessary, the treatment capacity of the coalescer 3 and the water absorption filter 5 can be reduced by adjusting the opening degrees of the first solenoid valve 14 and the second solenoid valve 15.
Preferably, an electromagnetic three-way valve 16 is arranged at the inlet of the water absorption filter 5, and a check valve 17 is connected to the outlet of the water absorption filter 5; a fourth pipeline 18 is arranged between one outlet of the electromagnetic three-way valve 16 and the outlet of the check valve 17. If the lubricating oil is already freed from water after the treatment in the coalescer 3, the suction filter 5 is deactivated by the adjustment of the three-way solenoid valve 16.
The above embodiments are preferred embodiments of the present invention, but the embodiments of the present invention are not limited to the above embodiments, and any other changes, modifications, substitutions, combinations, and simplifications which do not depart from the spirit and principle of the present invention should be equivalent replacement modes, and all are included in the scope of the present invention.
