Abstract

This utility model relates to the field of condenser technology and discloses an anti-water accumulation device for vacuuming a power plant condenser. The device includes a condenser with a gas-liquid mixing pipe internally connected to it. A separation tank is connected to the end of the gas-liquid mixing pipe furthest from the condenser. In this utility model, the gas-liquid mixture inside the condenser enters the separation tank through the gas-liquid mixing pipe. When the airflow carries droplets through a conical column, the droplets are adsorbed onto the surface by the column and converge and flow down under gravity along the guide channel, achieving gas-liquid separation. The conical column is irregularly distributed at the bottom of a fixed column. The separated liquid accumulates at the bottom of the separation tank and is discharged through a water pump via a water outlet pipe. The gas is drawn away by a vacuum pump through an air inlet pipe and finally discharged through an air outlet pipe. This prevents water molecules inside the condenser from entering the vacuum pump through the pipe, improving the service life of the components inside the vacuum pump. Simultaneously, by improving the vacuum stability of the vacuum pump, the efficiency of the condenser is increased.

Description

Technical Field

[0001] This utility model relates to the field of condenser technology, and in particular to a device for preventing water accumulation during vacuuming of a power plant condenser. Background Technology

[0002] Condensers are key equipment in thermal power plants, nuclear power plants, and other thermal systems. Their main function is to receive low-pressure steam discharged from the turbine, condense the steam into water through heat exchange with the cooling medium, and simultaneously maintain the high vacuum environment at the turbine exhaust port.

[0003] In existing condensers, during vacuuming, water molecules inside the condenser are carried by the airflow into the vacuum pipe. Some of the water vapor condenses into liquid water upon contact with the cold air inside the pipe, gradually accumulating and flowing along the pipe. When this accumulated water enters the vacuum device, it interferes with its normal operation. Long-term water accumulation can also accelerate the corrosion of internal components, shorten their service life, and even affect the condenser efficiency due to unstable vacuum levels. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a device for preventing water accumulation during vacuuming of a power plant condenser.

[0005] This utility model is achieved using the following technical solution: a water-prevention device for vacuuming a power plant condenser, comprising a condenser, wherein a gas-liquid mixing pipe is internally connected to the condenser, and a separation tank is connected to the end of the gas-liquid mixing pipe away from the condenser; a fixed column is provided on the inner wall of the separation tank, and a conical column is fixedly connected to the bottom of the fixed column; a guide groove is provided on the outer wall of the conical column; a water outlet pipe is internally connected to the separation tank, and a water pump is connected to the end of the water outlet pipe away from the separation tank; a pipeline is connected to the end of the water pump away from the water outlet pipe; an air inlet pipe is internally connected to the separation tank, and a vacuum pump is connected to the end of the air inlet pipe away from the separation tank; an air outlet pipe is internally connected to the vacuum pump.

[0006] Through the above technical solution, the gas-liquid mixture in the condenser enters the separation tank through the gas-liquid mixing pipe. When the airflow carries the droplets through the conical column, the droplets are adsorbed onto the surface by the column and flow down along the guide groove under the action of gravity, thus achieving gas-liquid separation. The conical column is irregularly distributed at the bottom of the fixed column. The separated liquid gathers at the bottom of the separation tank and is discharged through the water outlet pipe by the water pump. The gas is drawn away by the vacuum pump through the air inlet pipe and finally discharged from the air outlet pipe. This prevents water molecules inside the condenser from entering the vacuum pump through the pipe, thus improving the service life of the internal parts of the vacuum pump. At the same time, by improving the vacuum stability of the vacuum pump, the efficiency of the condenser is improved.

[0007] As a further improvement to the above solution, a sliding groove is provided on the inner wall of the separation tank, and a limiting block is slidably connected to the outer wall of the sliding groove. The limiting block is fixedly connected to the outer wall of the fixed column.

[0008] As a further improvement to the above solution, a handle is fixedly connected to the top of the fixed column, a sealing gasket is fixedly connected to the top of the separation tank, and a screw is slidably connected inside the separation tank.

[0009] As a further improvement to the above solution, the screw is threaded with a nut, the outer wall of the screw is slidably connected with a top cover, the top cover is fixedly connected with a pressure column, and the vacuum pump is internally connected with a pipe.

[0010] As a further improvement to the above scheme, an electromagnetic valve is connected to the end of the first pipeline away from the vacuum pump, and a second pipeline is connected to the end of the electromagnetic valve away from the vacuum pump. The second pipeline is connected to the inside of the separation tank.

[0011] With the above technical solution, when performing maintenance, personnel first remove the nut to detach it from the screw, at which point the screw can be removed from the top cover and inside the separator tank. After the top cover is detached from the top of the separator tank, the fixed column is moved by the handle, causing the fixed column to slide along the outer wall of the chute with the help of the limiting block. The conical column can then be removed to clean the scale on its surface, or to replace or repair it, ensuring that the water collection efficiency of the conical column is not affected.

[0012] As a further improvement to the above solution, a base plate is fixedly connected to the bottom of the separation tank, a support block is fixedly connected to the top of the base plate, and the support block is fixedly connected to the bottom of the water pump.

[0013] As a further improvement to the above solution, a support base is fixedly connected to the top of the base plate, and the support base is fixedly connected to the bottom of the vacuum pump.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This invention separates the gas and liquid mixture in the condenser into a separation tank through a gas-liquid mixing pipe. As the airflow carries the liquid droplets through the conical column, the droplets adhere to the surface due to the adsorption of the column and converge and flow down under gravity along the guide channel, thus achieving gas-liquid separation. The conical column is irregularly distributed at the bottom of the fixed column. The separated liquid gathers at the bottom of the separation tank and is discharged through a water pump via a water outlet pipe. The gas is drawn away by a vacuum pump through an air inlet pipe and finally discharged through an air outlet pipe. This prevents water molecules inside the condenser from entering the vacuum pump through the pipe, thus improving the service life of the internal components of the vacuum pump. At the same time, by improving the vacuum stability of the vacuum pump, the efficiency of the condenser is improved.

[0016] When this utility model is maintained by personnel, the nut is first removed to detach it from the screw, at which point the screw can be removed from the top cover and the inside of the separator tank. After the top cover is detached from the top of the separator tank, the fixed column is moved by the handle, causing the fixed column to slide along the outer wall of the chute with the help of the limiting block. The conical column can then be removed to clean the scale on its surface, or to replace or repair it, ensuring that the water collection efficiency of the conical column is not affected.

[0025] Example 1

[0026] Please combine Figure 1-5This embodiment discloses a water-prevention device for vacuuming a power plant condenser, comprising a condenser 1, a gas-liquid mixing pipe 2 internally connected to the condenser 1, a separation tank 3 connected to the end of the gas-liquid mixing pipe 2 away from the condenser 1, a fixing column 4 on the inner wall of the separation tank 3, a conical column 5 fixedly connected to the bottom of the fixing column 4, a guide groove 6 on the outer wall of the conical column 5, a water outlet pipe 7 internally connected to the separation tank 3, a water pump 8 connected to the end of the water outlet pipe 7 away from the separation tank 3, a pipe 9 connected to the end of the water pump 8 away from the water outlet pipe 7, an air inlet pipe 10 internally connected to the separation tank 3, a vacuum pump 11 connected to the end of the air inlet pipe 10 away from the separation tank 3, and an air outlet pipe 12 internally connected to the vacuum pump 11.

[0027] The inner wall of the separation tank 3 is provided with a sliding groove 13, and the outer wall of the sliding groove 13 is slidably connected to a limiting block 14, which is fixedly connected to the outer wall of the fixed column 4.

[0028] The top of the fixed column 4 is fixedly connected to a handle 15, the top of the separation tank 3 is fixedly connected to a sealing gasket 16, and the inside of the separation tank 3 is slidably connected to a screw 17.

[0029] The screw 17 is threadedly connected to a nut 18, and a top cover 19 is slidably connected to the outer wall of the screw 17. A pressure column 20 is fixedly connected inside the top cover 19, and a pipe 21 is connected inside the vacuum pump 11.

[0030] A solenoid valve 22 is connected to the end of pipe 21 away from vacuum pump 11. A second pipe 23 is connected to the end of solenoid valve 22 away from vacuum pump 11. Pipe 23 is connected to the inside of separation tank 3.

[0031] A bottom plate 24 is fixedly connected to the bottom of the separator tank 3, and a support block 25 is fixedly connected to the top of the bottom plate 24. The support block 25 is fixedly connected to the bottom of the water pump 8.

[0032] A support base 26 is fixedly connected to the top of the base plate 24, and the support base 26 is fixedly connected to the bottom of the vacuum pump 11.

[0033] The implementation principle of the anti-water accumulation device for vacuuming a power plant condenser in this embodiment is as follows: The gas-liquid mixture in the condenser 1 enters the separation tank 3 through the gas-liquid mixing pipe 2. When the airflow carries the droplets through the conical column 5, the droplets are adsorbed by the column and adhere to the surface. They converge and flow down along the guide groove 6 under the action of gravity, realizing gas-liquid separation. At the same time, the conical column 5 is irregularly distributed at the bottom of the fixed column 4. The separated liquid gathers at the bottom of the separation tank 3 and is discharged through the water outlet pipe 7 by the water pump 8 through the pipe 9. The gas is drawn away by the vacuum pump 11 through the air inlet pipe 10 and finally discharged from the air outlet pipe 12. This prevents water molecules inside the condenser 1 from entering the vacuum pump 11 through the pipe, thereby improving the service life of the parts inside the vacuum pump 11. At the same time, by improving the vacuum stability of the vacuum pump 11, the efficiency of the condenser 1 is improved. When personnel perform maintenance, they first remove the nut 18 to detach it from the screw 17. At this time, the screw 17 can be removed from the top cover 19 and the inside of the separation tank 3. After the top cover 19 detaches from the top of the separator tank 3, the handle 15 moves the fixing column 4, causing the fixing column 4 to slide the conical column 5 against the outer wall of the slide groove 13 with the help of the limiting block 14. This allows the conical column 5 to be removed for cleaning of surface scale, or for replacement or repair, ensuring that the water collection efficiency of the conical column 5 is not affected. During installation, pressure is applied to the top cover 19 via the screw 17, compressing the sealing gasket 16. The deformation of the sealing gasket 16 achieves a seal, preventing gas leakage. Simultaneously, the top cover 19 moves the pressure column 20. The pressure column 20 compresses the fixed column 4, thereby limiting the displacement of the fixed column 4 and ensuring the stable position of the conical column 5 in the separation tank 3. Due to the influence of the height difference, the solenoid valve 22, through the connection with the first pipe 21, can discharge any water that may remain inside the vacuum pump 11 into the separation tank 3 through the second pipe 23. At the same time, the support block 25 and the support seat 26 are fixed on the top of the base plate 24, respectively. The support block 25 supports the water pump 8, and the support seat 26 supports the vacuum pump 11, thereby ensuring the overall stability of the equipment.

[0034] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
