Description

Technical Field

[0001] This invention belongs to the field of water treatment technology, and in particular relates to a water quality testing system and method for power plants. Background Technology

[0002] When generating electricity through thermal power plants, circulating water needs to be used repeatedly within the system. During this circulation process, impurities will appear in the circulating water, which will affect the efficiency of power generation. Therefore, various agents need to be used to purify the circulating water. Before purification, the staff needs to test the water quality of the circulating water.

[0003] Existing circulating water detection devices require manual intervention for data collection, which leads to delays in data acquisition and analysis. This increases the number of test pieces and risks for fault diagnosis, reduces the real-time performance of the system, and manual collection usually involves installing a drain valve on the pipeline. Since the content of sediment and floating matter varies at different locations in the circulating water, there is a possibility of inaccurate manual detection.

[0109] The setup of two of each type of sensor is used to verify the accuracy of the data between them, so as to avoid inaccurate feeding during subsequent circulating water treatment due to sensor problems, which would affect the purification quality of the circulating water.

[0110] The circulating water is stirred evenly through the branch pipes, vertical agitator 81, and horizontal agitator 82, so that the sensor detection data is accurate.

[0112] Example 2

[0113] Another specific embodiment of the present invention discloses a detection method for a power plant water quality detection system. The method uses the power plant water quality detection system of Embodiment 1 to detect circulating water. The detection method for the power plant water quality detection system includes:

[0114] Step 1: Connecting the circulating water.

[0115] The circulating water pipeline of the power plant is cut off and connected to the power plant water quality monitoring system through the inlet pipeline 2 and the outlet pipeline 3; the circulating water of the power plant is connected to the main pipeline 1.

[0116] Step 2: Input power into the power supply device 4.

[0117] The power supply device 4 rotates using the flow of circulating water.

[0118] The flow of circulating water drives the first rotating plate 42 to rotate, which in turn drives the first rotating shaft 41 to rotate. The first rotating shaft 41 drives the first gear 43 and the second gear 44 to rotate. The first gear 43, in cooperation with the closed rack 46, drives the third gear 45 to rotate. The second gear 44 directly meshes with the third gear 45. The purpose of the first gear 43 and the second gear 44 in providing power to the third gear 45 is to provide greater torque, thereby providing sufficient power to the anti-rotation transmission device 5 connected to it.

[0119] Step 3: Store the force provided by the power supply device 4.

[0120] The power supply device 4 rotates at high torque and low speed through the anti-rotation transmission device 5, which stores energy for the power release device 6.

[0121] The power supply device 4 drives the threaded rod 51 to rotate, the threaded rod 51 drives the fourth gear 52 to rotate, the fourth gear 52 drives the driving bevel gear 53 to rotate, the driving bevel gear 53 drives the driven bevel gear 54 to rotate, and the driven bevel gear 54 provides power to the power release device 6.

[0122] Step 4: Provide kinetic energy for the vibration of the vibration device 7.

[0123] The power release device 6 provides energy to the vibration device 7, which in turn drives the filter device 2 to vibrate rapidly.

[0124] The square rod 6a2 drives the inner square groove column 6a3 to rotate, which in turn drives the actuating rod 6a4 to rotate. 6a4 drives the pushing column 6b3 to rotate, which in turn drives the rotating disk 6b1 to rotate. The rotating disk 6b1 then drives the pull rope 6b4 to rotate. After the actuating rod 6a4 contacts the guide block 6c2, it disengages from the pushing column 6b3. The pushing column 6b3 is no longer under force, and the pull rope 6b4 is no longer under the force provided by the rotating disk 6b1. Therefore, the pull rope 6b4... Under the action of the telescopic spring 6d4, the second plate 6d4 moves to one side of the second plate 6d4. The second plate 6d4 moves linearly to one side under the action of the telescopic spring 6d4. The second plate 6d4 drives the rigid rack 74 to move linearly. The rigid rack 74 drives the fifth gear 73 to rotate. The fifth gear 73 drives the vibration shaft 71 to rotate. The vibration shaft 71 drives the eccentric cylinder 72 to rotate. The eccentric cylinder 72 drives the filter device 2 to vibrate through the connecting rod 75, the connecting column 76 and the connecting plate 77.

[0125] Step 5: Filter out large solid pieces.

[0126] When the filter device 2 vibrates, large solid pieces will be shaken off its surface and fall into the drain pipe 3.

[0127] Step 6: Stir and mix the circulating water.

[0128] The circulating water is stirred evenly by vertical and horizontal agitators.

[0129] Step 7: Test the quality of the circulating water.

[0130] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.

The square rod is slidably connected inside the inner square groove column, and the lifting spring is fixed on one side of the inner square groove column, while the toggle rod is fixed on the other side. The square rod is fixedly connected to the driven bevel gear. The pulling component includes a rotating disk, a rotating bearing seat, a pushing column, and a pull rope. The rotating bearing seat is fixed in the middle of the upper end of the rotating disk, and two symmetrically distributed pushing columns are provided at the lower end of the rotating disk. One end of the pull rope is fixed to the side of the rotating disk. The other end of the pull rope is connected to the pushing component. When the toggle rod rotates to a certain angle, it contacts the pushing column. Guide blocks are fixed at both ends of the lower side of the semi-cylinder. When the toggle rod rotates to a certain angle, it contacts the guide block, and the toggle rod will disengage from the pushing column. The second plate moves linearly to one side under the action of the telescopic spring. The pulling component drives the pushing component to reciprocate. The first plate and the second plate are connected by a telescopic rod and a telescopic spring; an eccentric cylinder and a fifth gear are fixed on the vibration shaft, the fifth gear meshes with a hard rack, and the hard rack is fixedly connected to the second plate of the pushing component; a connecting rod is rotatably connected to the eccentric cylinder, and a connecting column is rotatably connected to the end of the connecting rod, and a connecting plate is fixed to the lower end of the connecting column; the connecting column drives the inclined filter plate to vibrate through the connecting plate.
