Description

The integrated reconditioner of high pressure

The utility model relates to a kind of refining plant that filters well cuts, at the adjusting oil of Steam Turbine use in the power system and the filtration unit of lubricating oil.

Steam Turbine need recycle and regulate oil and lubricating oil in the power system, after for some time, just contains a certain amount of impurity in the oil, needs the elimination well cuts.In regulating oil and lubricating oil, regulating oil be high-pressure oil, and lubricating oil is low pressure oil, and the refining plant 13 of oil be a low-voltage device at present, thus can only filtering lubricant oil 14, can not be oily 15 filtrations of adjusting simultaneously, function singleness (referring to Fig. 1); Secondly it adopts the primary purification device, in order to reach the purification grade of power system requirement, must adopt high-precision filtering net, and this has improved the cost of refining plant on the one hand, has come difficulty also on the other hand the cleaning and filtering guipure; Big, the Heavy Weight of this refining plant volume is difficult for on-the-spot the installation at last.

The purpose of this utility model provides that a kind of function is many, cost is low, purifies the grade height, cleans convenience, compact construction, is easy to the integrated reconditioner of field erected high pressure.

The purpose of this utility model is achieved in that this filtration unit is divided into settling chamber, inlet space and filtration chamber from bottom to top, at filtration chamber's lining filter screen and magnet is arranged, and filtration chamber's oil circuit end takes back oil pipe, and the bottom, settling chamber is connected to wash water valve.The utility model is installed on the high voltage startup scavenge delivery---in the bleed off circuit of high-pressure line, when not rolling off the production line, unit can not exchange fuel-economizing simultaneously and lubricating oil filters.When oil flow to the inlet space of filtration unit, the impurity that particle is bigger was fallen into the settling chamber under action of gravity, and oil enters the filtration chamber then, the magnetic diffusivity impurity absorption is to magnet in the oil, non-magnetic conduction impurity absorption is to filter screen, and the oil after the purification flows back to the high-pressure line from the filtration chamber, and scavenging process finishes.Owing to adopted magnet, increased once on the one hand and filtered, improved the purification grade, on the other hand, magnet can will filter less than filter screen precision magnetic impurity, so, requirement to the filter screen precision can be hanged down relatively, has both reduced cost, the convenient again filter screen that cleans.Be adsorbed onto the impurity on the filter screen, produce a kind of chromium complex, this chromium complex will come off in the settling chamber through the impact of high-pressure high-flow oil, open the wash water valve of bottom, settling chamber, and the cleaning throw out has reduced wash number like this, has improved efficient, has reduced the cleaning cost.

The utility model compared with prior art has the following advantages:

Therefore 1, the utility model belongs to high-pressure high-flow, can be installed in the bleed off circuit behind the high voltage startup oil pump, very easily installs at this place, does not roll off the production line can exchange fuel-economizing simultaneously and lubricating oil filters, and has improved efficient.

2, behind the employing secondary filter, under the identical situation of filter screen precision, can improve the purification grade of oil greatly; Purifying under the identical situation of grade, the precision of filter screen can reduce, thereby reduces cost, and easy to clean.

3, owing to be provided with the settling chamber, and establish wash water valve, blowdown and clean very easy in the bottom, settling chamber.

Further specify the utility model below in conjunction with accompanying drawing.

Fig. 1 is the existing position block diagram of low pressure oil refining plant in system.

Fig. 2 is the position block diagram of the utility model in system.

Fig. 3 is structural representation of the present utility model (two filtration unit parallel connection).

Fig. 4 is the skeleton diagram that four filtration units connect.

Referring to Fig. 3, filtration unit 13 is divided into settling chamber 3, inlet space 5 and filtration chamber 7 from bottom to top.A string permanent magnet ring 6 is arranged on the center stand column 9 of filtration chamber, around the magnet ring filter screen 8 is arranged, filtration chamber's oil circuit end takes back oil pipe 4, and wash water valve 1 is arranged at the bottom, settling chamber.The utility model 17 is installed on high voltage startup oil pump 16 output tubes---in the bleed off circuit of high-pressure line (referring to Fig. 2), unit does not roll off the production line and can exchange fuel-economizing 15 simultaneously and lubricating oil 14 filters.When oil when oil pipe 2 flows to the inlet space of filtration unit, the impurity that particle is bigger is fallen into the settling chamber under action of gravity, oil enters the filtration chamber then, the magnetic diffusivity impurity absorption is to magnet in the oil, the non-magnetic impurity absorption is to filter screen, oil after the purification flows back to high-pressure line from the filtration chamber by used oil pipe 4, and scavenging process finishes.Owing to adopted magnet, increased once on the one hand and filtered, improved the purification grade, on the other hand, magnet can will filter less than filter screen precision magnetic impurity, so, requirement to the filter screen precision can be hanged down relatively, has both reduced cost, the convenient again filter screen that cleans.Be adsorbed onto the impurity on the filter screen, produce a kind of chromium complex, this chromium complex will come off in the settling chamber through the impact of high-pressure high-flow oil, open the wash water valve of bottom, settling chamber, and the cleaning throw out has reduced wash number like this, has improved efficient, has reduced the cleaning cost.

In the present embodiment, the utility model is provided with pressure reduction warning device 12 on transition pipeline, automatic bypass valve 10 and tensimeter 11 are set on top, filtration chamber, when filter screen stops up (force value is 0.35Mpa), the pressure reduction warning device pipes, also can read the pressure reduction number by tensimeter, as on-the-spot unmanned the discovery, pressure reduction continues to raise, when pressure reduction rises to 0.5Mpa, by-pass valve 10 is opened automatically, and oil flows to oil outlet under by-pass valve, prevents that filter screen from destroying.

In order to improve purification efficiency, can be with two filtration units, 13 in parallel uses, the oil inlet pipe that is about to two filtration units connects together, and oil outlet pipe connects together.Fig. 3 is exactly this use-pattern.

In order to improve purification efficiency, and improve and purify grade, use can also combine four filtration units, referring to Fig. 4, being about to two identical refining plants of filtration grade is together in parallel as one group, and then two groups be together in series, one group that filtration grade is low as the first step, another group that filtration grade is high is as the second stage, filtration grade is directly proportional with the magneticstrength of magnet and the precision of filter screen, oil at first carries out coarse filtration through first group of filtration unit, carries out finly filtration through second group of filtration unit then.
