Description
Technical Field
The utility model relates to a sealed oil system oil gas purification technical field of thermal power plant, more specifically says, relates to an oil gas purification device of sealed oil system.
Background
The vacuum oil purifying device of the existing thermal power plant is arranged in a generator sealing oil system, an inlet is connected with an empty side oil return sealing box, an outlet is connected with an empty side sealing oil pump inlet main pipe, and the inlet oil of the empty side sealing oil pump is purified by a bypass. The oil source of the air side sealing oil pump is not an independent oil tank, and the possibility of pollution is relatively high; the two air side sealing oil pumps are screw pumps which require that the oil source must be highly purified; in addition, clean oil is also necessary and advantageous for proper operation of the seal shoe. However, the existing vacuum oil purifier access mode cannot avoid the problem that the sealing oil carries air to enter the generator to influence the purity of hydrogen when air leaks into the hydrogen side oil return tank when the hydrogen side oil return tank is not tight and the air side sealing oil leaks into the hydrogen side sealing oil.
SUMMERY OF THE UTILITY MODEL
In order to overcome the technical defect, the utility model provides an oil gas purification device of sealed oil system.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
an oil-gas purification device of a sealing oil system comprises an air side sealing oil inlet pipe, an air side sealing oil pump inlet main pipe, a hydrogen side oil return tank and a hydrogen side oil return tank oil outlet pipeline, wherein the air side sealing oil inlet pipe and the air side sealing oil pump inlet main pipe are both communicated with the hydrogen side oil return tank; the hydrogen side oil return tank oil outlet pipeline is provided with a hydrogen side sealing oil pump inlet valve, the hydrogen side oil return tank oil outlet pipelines at the front end and the rear end of the hydrogen side sealing oil pump inlet valve are communicated through a connecting pipeline, and the connecting pipeline is provided with a vacuum oil purifier and a vacuum oil purifier oil pump.
Furthermore, a manual vacuum oil purifier inlet door is installed on a connecting pipeline at the front end of the vacuum oil purifier, and a manual vacuum oil purifier outlet door is installed on a connecting pipeline at the rear end of an oil pump of the vacuum oil purifier.
The utility model has the advantages that: the original sealing oil system can be accessed compatibly, so that the maintainers of the power plant can perform self-processing in the plant, and the reconstruction cost is low; through the improvement, the air leakage when the hydrogen side oil return tank is not tight and the air side sealing oil leaks into the hydrogen side sealing oil can be avoided, so that the air leakage possibility of the whole system is further reduced, and the influence of air contained in the sealing oil on the purity of hydrogen is reduced; the newly installed manual door for the inlet of the vacuum oil purifier and the manual door for the outlet of the vacuum oil purifier can be effectively isolated from the original system, and the maintenance is convenient; the mode of parallel operation is adopted, and the original pipeline is not disconnected during operation, so that the mode not only ensures online oil filtering, but also ensures the operation safety of the system.
Drawings
Fig. 1 is a schematic structural diagram of an oil gas purification device of a sealed oil system according to the present invention;
in the figure, 1, an oil inlet pipe is sealed on the empty side; 2. an inlet main pipe of the oil pump is sealed at the empty side; 3. a hydrogen side oil return tank; 4. an oil outlet pipeline of the hydrogen side oil return tank; 5. a hydrogen side seal oil pump inlet valve; 6. connecting a pipeline; 7. a manual door of an inlet of the vacuum oil purifying device; 8. a vacuum oil purification device; 9. a manual door of the outlet of the vacuum oil purifying device; 10. an oil pump of a vacuum oil purifying device.
Detailed Description
The technical solution in the embodiment of the present invention will be clearly and completely described below by combining with the drawings in the embodiment of the present invention, as shown in fig. 1, an oil-gas purifying device of a sealing oil system includes an empty-side sealing oil supply pipe 1, an empty-side sealing oil pump inlet main pipe 2, a hydrogen-side oil return tank 3 and a hydrogen-side oil return tank outlet pipe 4, the empty-side sealing oil supply pipe 1 and the empty-side sealing oil pump inlet main pipe 2 are both communicated with the hydrogen-side oil return tank 3, an original vacuum oil purifying device is connected between the empty-side sealing oil supply pipe 1 and the empty-side sealing oil pump inlet main pipe 2, and the hydrogen-side oil return tank 3 is communicated with the hydrogen-side sealing oil pump through the hydrogen-side oil return tank outlet pipe 4; a hydrogen side oil return tank inlet valve 5 is arranged on the hydrogen side oil return tank oil outlet pipeline 4, the hydrogen side oil return tank oil outlet pipelines 4 at the front end and the rear end of the hydrogen side oil return tank inlet valve 5 are communicated through a connecting pipeline 6, and a vacuum oil purifier 8 and a vacuum oil purifier oil pump 10 are arranged on the connecting pipeline 6; a manual vacuum oil purifier inlet door 7 is arranged on a connecting pipeline 6 at the front end of a vacuum oil purifier 8, and a manual vacuum oil purifier outlet door 9 is arranged on the connecting pipeline 6 at the rear end of a vacuum oil purifier oil pump 10.
In this embodiment, the inlet valve 5 of the hydrogen-side seal oil pump is in a normally open state, and after the normal hydrogen-side seal oil is vacuum filtered from the hydrogen-side oil return tank outlet pipeline 4 to the vacuum oil purifier 8, the normal hydrogen-side seal oil is pumped back to the hydrogen-side oil return tank outlet pipeline 4 through the vacuum oil purifier oil pump 10; under the accident condition, after the vacuum oil purifier 8 works abnormally, the hydrogen side sealing oil passes through the hydrogen side sealing oil pump inlet valve 5 and then supplies oil to the hydrogen side sealing oil pump, and the operation mode ensures that the online oil filtering is realized during normal operation and the safe operation of the sealing oil system can be prevented when the vacuum oil purifier 8 breaks down.
