Description

Technical Field

[0002] When the turbine generator is in operation, the hydrogen used for cooling inside the generator is sealed by sealing oil inside the generator to prevent leakage. Due to changes in pressure and temperature, a certain amount of dissolved gas and water in the oil will overflow. The overflowed non-condensable gas and water will contaminate the hydrogen, causing the hydrogen purity to decrease and the hydrogen dew point of the generator to increase, threatening the safe operation of the unit. In addition, the reduction of hydrogen purity in the generator will also increase the wind friction loss of the generator and increase the cost of power generation. There are certain defects in use.

[0026] Compared with the prior art, the invention has the following beneficial effects: the treatment and purification device for sealing oil can remove 99% of dissolved gas and 99% of dissolved water by high vacuum evaporation; the inlet and outlet valves isolate the device from the host system; when the device is abnormal or shut down, the inlet and outlet valves are automatically closed and isolated from the system; the vacuum pump of the device adopts a large-flow rotary vane vacuum pump, which is durable; the vacuum pump is equipped with an oil purification system, which can efficiently remove water and impurities in the vacuum pump oil, avoiding the problem of high failure rate of vacuum pumps in traditional vacuum oil purification devices, and realizing maintenance-free vacuum pumps; the operating vacuum range of the device reaches above -100kpa, ensuring efficient removal of water and non-condensable gas, ensuring high vacuum operation of the evaporator, and not using electric heating, avoiding the problem of local over-temperature caused by electric heating and accelerating oil aging, and avoiding the potential safety hazards caused by electric heating failure;

[0027] 1. It is composed of import pump, export pump, vacuum pump, vacuum pump oil purification system, evaporator, evaporator defoaming system, etc. It removes non-condensable gas, impurities and water in the sealing oil through high vacuum and physical defoaming technology. The outlet pump transports the oil to the precision filter, and the impurities in the oil are filtered out through the precision filter. The filtered oil returns to the main engine sealing system to prevent water and air from polluting the hydrogen. Purification components are set inside and outside the box. When the sealing oil needs to be purified during the production process, the drive motor is started to drive the rotating shaft to rotate. After the rotating shaft rotates, the first pulley and the second pulley can be used to drive the hollow rod to rotate. After the hollow rod rotates, the rotating gear can be driven to rotate. After the rotating gear rotates, the two movable rods are engaged with the two racks to make the two movable rods slide on the telescopic frame and approach each other. The movable rod moves and drives the T-shaped rod to move at the same time. After the T-shaped rod moves, it can slide inside the sliding groove. Due to the inclined setting of the sliding groove, the movement of the T-shaped rod can push the fixed plate downward, and then drive the filter barrel downward. After the filter barrel moves downward, the plugging head can be inserted into the inside of the sewage outlet, so that the inside of the filter barrel remains closed. After the movable rod moves, the positioning block fits the telescopic frame. The movable rod no longer moves. Then, when the hollow rod rotates, it drives The rotating gear rotates together with the rack, so that the movable rod drives the filter barrel to rotate. When the movable rod drives the telescopic frame to rotate in a circle, the spherical piece is driven to slide inside the annular groove on the fixed ring, and the rotation of the telescopic frame is limited, so that the sealing oil can be put into the feed hopper, so that the sealing oil can enter the interior of the filter barrel through the hollow rod. The centrifugal force brought by the rotation of the filter barrel purifies the sealing oil, so that impurities remain in the interior of the filter barrel. After the sealing oil is purified, the filter barrel stops rotating, so that the filter barrel can be reset, and the plugging head leaves the drain port, and the impurities inside the filter barrel can enter the interior of the fixed bucket through the drain port, so that the impurities enter the connecting pipe. The through hole provided on the connecting pipe is convenient for the residual sealing oil to be led out, and then the impurities are discharged through the drain pipe. Through the purification component, the filter barrel can be automatically blocked when the sealing oil is purified. After the sealing oil stops purifying, the filter barrel can be opened, so that sewage can be automatically discharged after the sealing oil is purified, so as to avoid the difficulty of impurities to be discharged and avoid affecting the filtering and purification of the sealing oil.

[0028] 2. When the filter barrel is moved to block the sewage outlet, the movable sleeve can be driven to slide on the positioning rod. After the movable sleeve moves, the support spring can be stretched. During the rotation of the filter barrel, the two arc blocks can be driven to slide inside the limiting ring groove, so that the rotation stability of the filter barrel can be improved after the filter barrel is rotated. After the filter barrel stops rotating, it can be reset under the action of the support spring, so that the sewage outlet on the filter barrel can be opened, thereby limiting the rotation of the filter barrel and facilitating the resetting of the filter barrel.

[0029] 3. The rotating shaft can drive the rotating blades to rotate while rotating. After the rotating blades rotate, the outside air can be brought into the box through the air inlet hole, and then enter the air inlet pipe under the guidance of the fixed cover, and then enter the annular pipe. After that, the air can be ejected through the air outlet pipe, so that the air outlet pipe can blow air while purifying the sealing oil, and the inner wall of the box can be blown, which can assist the sealing oil attached to the inner wall of the box to drip, avoid wasting the sealing oil, and improve practicality.

The non-condensable gas, impurities and water in the sealing oil are removed by high vacuum and physical defoaming technology. The outlet pump 10 transports the oil into the box 1, and the impurities in the oil are filtered out by the purification component 2 inside the box 1. The filtered oil returns to the main engine sealing system to prevent water and air from contaminating the hydrogen. The purification component 2 is set inside and outside the box 1. When the sealing oil needs to be purified during the production process, the drive motor 204 is started to drive the rotating shaft 2041 to rotate. After the rotating shaft 2041 rotates, the first pulley 205 and the second pulley 206 can cooperate to drive the hollow rod 202 to rotate. After the hollow rod 202 rotates, it can drive the rotating gear 209 to rotate. After the rotating gear 209 rotates, the two movable rods are engaged with the two racks 212. 211 slides on the telescopic frame 210 and approaches each other. The movable rod 211 moves while driving the T-shaped rod 2111 to move. After the T-shaped rod 2111 moves, it can slide inside the sliding groove 217. Since the sliding groove 217 is tilted, the movement of the T-shaped rod 2111 can push the fixed plate 216 to move downward, and then drive the filter barrel 201 to move downward. After the filter barrel 201 moves downward, the plugging head 104 can be inserted into the interior of the sewage outlet 2011, so that the interior of the filter barrel 201 remains closed. After the movable rod 211 moves, the positioning block 213 fits the telescopic frame 210. The movable rod 211 no longer moves. Then, when the hollow rod 202 rotates The rotating gear 209 is driven to rotate together with the rack 212, so that the movable rod 211 drives the filter barrel 201 to rotate. When the movable rod 211 drives the telescopic frame 210 to rotate in a circle, it drives the spherical member 218 to slide inside the annular groove 221 on the fixed ring 220, and limits the rotation of the telescopic frame 210. The sealing oil can be put into the feed hopper 207, so that the sealing oil can enter the inside of the filter barrel 201 through the hollow rod 202. The centrifugal force brought by the rotation of the filter barrel 201 purifies the sealing oil, so that impurities remain in the inside of the filter barrel 201. After the sealing oil is purified, the filter barrel 201 stops rotating, so that the filter barrel 201 can be reset, and the sealing The plug 104 leaves the drain port 2011, and the impurities in the filter barrel 201 can enter the fixed bucket 106 through the drain port 2011, so that the impurities enter the connecting pipe 107. The through hole provided on the connecting pipe 107 is convenient for the residual sealing oil to be discharged, and then the impurities are discharged through the drain pipe 108. The filter barrel 201 can be automatically blocked by the purification component 2 when the sealing oil is purified. After the sealing oil stops purifying, the filter barrel 201 can be opened, so that the sewage can be automatically discharged after the sealing oil is purified, so as to avoid the difficulty of impurities to be discharged, avoid affecting the filtering and purification of the sealing oil, and avoid affecting the production efficiency of the sealing oil;

[0060] When the filter barrel 201 is moved to block the sewage outlet 2011, the movable sleeve 227 can be driven to slide on the positioning rod 226. After the movable sleeve 227 moves, the support spring 229 can be stretched, and the two arc blocks 224 can be driven to slide inside the limiting ring groove 223 during the rotation of the filter barrel 201, so that the rotation stability of the filter barrel 201 can be improved after the rotation of the filter barrel 201 is performed, and after the filter barrel 201 stops rotating, it can be reset under the action of the support spring 229, so that the sewage outlet 2011 on the filter barrel 201 can be opened, and then the rotation of the filter barrel 201 is limited at the same time When the filter barrel 201 is reset, the rotating shaft 2041 can drive the rotating fan blade 231 to rotate while rotating. After the rotating fan blade 231 rotates, the outside air can be brought into the interior of the box body 1 through the air inlet hole 234, and then enter the air inlet pipe 233 under the guidance of the fixed cover 232, and then enter the annular tube 235. After that, the air can be ejected through the air outlet pipe 236, so that the air outlet pipe 236 can blow air while purifying the sealing oil, and the inner wall of the box body 1 can be blown, which can assist the sealing oil attached to the inner wall of the box body 1 to drip, avoid wasting the sealing oil, and improve practicality.
