Background technique
The electrical equipments such as transformer, mutual inductor, breaker play the mineral insulating oil of insulating effect, are from containing interconnection
The product of the petroleum refining of alkane diameter, cycloalkanes diameter and fragrant diameter, has the function of radiate arc extinguishing and information carrier.However, when insulation
Oil can generate furfural during refining, and the standard of general fresh oil is that furfural content is no more than 0.05ppm.Insulating oil is in equipment
By device temperature, apparatus insulated son, gradually aging is influenced in operation, and furfural content can gradually rise.Abnormal furfural content
It will affect appointees and equipment normally judged.Therefore, how to remove the furfural content in insulation of electrical installation oil is to ensure
The safe and stable operation of electrical equipment is a problem urgently to be resolved.
Summary of the invention
The invention discloses a kind of special equipments of furfural in removal insulation of electrical installation oil, using double tower absorption, by turns
Work disposably removes furfural without shutdown more novel sorbents, easy to use, reliable, quick.
The present invention is achieved by the following technical solutions:
The special equipment of furfural in a kind of removal insulation of electrical installation oil, including the first adsorption tower, the second adsorption tower and true
Empty separation system, insulating oil successively passes through inlet valve, preliminary filter, oil-feed pump and heater by oil pipe, by the heater
It is equipped with two-way oil pipe afterwards, is connected respectively with first adsorption tower and the second adsorption tower, is inhaled from first adsorption tower and second
The insulating oil that attached tower comes out pools a pipeline, and enters vacuum separation system, and described vacuum separation system one end is successively gone here and there
Join air-cooled cooler, oily device separator and vacuum pump, the vacuum separation system is additionally provided with one end insulation oil export, successively passes through
Oil drain pump, fine filter, flowmeter and delivery valve.
Further, adsorbent is equipped in first adsorption tower and the second adsorption tower.
Further, heating device is equipped in first adsorption tower and the second adsorption tower.
Further, first adsorption tower and the second adsorption tower are connected with PLC.
Compared with prior art, the beneficial effects of the present invention are:
1, it is equipped with hypersober in the first adsorption tower and the second adsorption tower of the invention, can effectively adsorbed in oil
Furfural, and the activity that can restore adsorbent is baked by the heating in tower, it can reuse；
2, of the invention using double tower absorption, work by turns, without shutting down more novel sorbents in whole work process, use
It is convenient, reliable, quick；
3, the disposable removal furfural of the present invention is avoided previous traditional handicraft and is asked using the various environmental protection of method for washing bring
Topic, it is ensured that electrical equipment safe and stable operation, to generate apparent economic results in society.

Specific embodiment
The following further describes the present invention with reference to the drawings:
The special equipment of furfural during a kind of removal insulation of electrical installation is oily, including the first adsorption tower 5,6 and of the second adsorption tower
Vacuum separation system 7, insulating oil successively passes through inlet valve 1, preliminary filter 2, oil-feed pump 3 and heater 4 by oil pipe, by institute
It is equipped with two-way oil pipe after stating heater 4, is connected respectively with first adsorption tower 5 and the second adsorption tower 6, from first absorption
The insulating oil that tower 5 and the second adsorption tower 6 come out pools a pipeline, and enters vacuum separation system 7, the vacuum separation system
7 one end of uniting are sequentially connected in series air-cooled cooler 8, oily device separator 9 and vacuum pump 10, the vacuum separation system 7 and are additionally provided with one end
Insulate oil export, successively passes through oil drain pump 11, fine filter 12, flowmeter 13 and delivery valve 14.
Further, adsorbent is equipped in first adsorption tower 5 and the second adsorption tower 6.
Further, heating device is equipped in first adsorption tower 5 and the second adsorption tower 6.
Further, first adsorption tower 5 and the second adsorption tower 6 are connected with PLC.
The present invention utilizes vacuum outgas, dehydration, fine filter core removing impurities, in addition the adsorbent multifunctional comprehensive of profession
Method removes the furfural in oil removing.Principle: the adsorbent activity in the first adsorption tower 5 and the second adsorption tower 6 has certain saturation value,
Adsorbent needs high temperature to bake by 2% or 4% proportional arrangement in oil after adsorbent activity saturation under normal circumstances, dries
The dry activity to restore it will shut down replacement adsorbent after adsorbent activity saturation in practical work process.The present invention
Using double tower absorption, by turns the method to work, after 5 adsorbent of the first adsorption tower saturation, by PLC automatic control program, certainly
It is dynamic to be switched to the second adsorption tower 6 to adsorb, while heating bakes the activity for restoring adsorbent, so weight to the first adsorption tower 5 automatically
It returns to work work, without shutting down more novel sorbents in whole work process, disposably removes the furfural in oil removing, it is convenient, reliable, quick.
