Description

Technical Field

[0001] This application relates to the field of water treatment technology, and more particularly to a power plant water treatment system. Background Technology

[0002] Power plant water refers to the water resources used by power plants during the power generation process. It is generally divided into domestic water, industrial water (i.e., power generation water) and fire-fighting water. Due to the special operating needs of power plants, their water consumption is not only large, but also subject to strict requirements on water quality.

[0003] Currently, existing technologies still have some shortcomings in treating various types of water:

[0004] 1. After introducing various types of water into the power plant, since most power plants use river water or groundwater, river water and groundwater often carry a large amount of gravel and silt. If gravel and silt enter the reservoir, the reservoir needs to be cleaned frequently, resulting in a high maintenance frequency for the reservoir.

[0005] 2. At the same time, if the introduced water contains a high content of acidic substances, it can easily cause corrosion of the power plant's pipelines after the water enters the pipelines, thus requiring the pipelines to be replaced. Utility Model Content

[0006] To address the aforementioned problems, this application provides a power plant water treatment system that can solve these problems.

[0007] To achieve the objectives of this application, the following technical solution is provided:

[0008] This application provides a power plant water treatment system, including: a domestic water tank, an industrial water tank, a fire water tank, and a water supply pipe. The water supply pipe is provided with three branch pipes, which are vertically corresponding to the domestic water tank, the industrial water tank, and the fire water tank, respectively. The bottom walls of the domestic water tank, the industrial water tank, and the fire water tank are all provided with drainage pipes.

[0009] Treatment boxes can be detachably installed on the domestic water tank, industrial water tank and fire water tank. The upper end of the treatment box is provided with an opening.

[0033] Figure 1-7 A power plant water treatment system provided in this application includes: a domestic water tank 1, an industrial water tank 2, a fire water tank 3, and a water supply pipe 4. The water supply pipe 4 is provided with three branch pipes 41, which are vertically corresponding to the domestic water tank 1, the industrial water tank 2, and the fire water tank 3, respectively. The bottom walls of the domestic water tank 1, the industrial water tank 2, and the fire water tank 3 are all provided with drainage pipes 42. The water pump installed on the water supply pipe 4 transports water from the water source to the domestic water tank 1, the industrial water tank 2, and the fire water tank 3 through the water supply pipe 4 and the branch pipes 41. The drainage pipes 42 in the domestic water tank 1, the industrial water tank 2, and the fire water tank 3 transport domestic water, industrial water, and fire water to various water systems of the power plant through the installed water pumps. This is prior art and will not be described in detail here.

[0034] In one possible implementation, treatment boxes 5 can be detachably installed on the domestic water tank 1, industrial water tank 2, and fire-fighting water tank 3. L-shaped mounting brackets 51 are fixedly installed on both sides of each of the three treatment boxes 5. A mounting bolt 52 is threadedly rotatably installed at one end of each L-shaped mounting bracket 51. The L-shaped mounting brackets 51 are threadedly rotatably connected to the upper end faces of the domestic water tank 1, industrial water tank 2, and fire-fighting water tank 3 via the mounting bolts 52. By using the L-shaped mounting brackets 51 and mounting bolts 52, the three treatment boxes 5 can be respectively assembled onto the upper end faces of the domestic water tank 1, industrial water tank 2, and fire-fighting water tank 3. An opening is provided at the top of each treatment box 5. The inner cavity of the treatment box 5 is divided into a first treatment chamber 53 and a second treatment chamber 54. Through the opening and the first treatment chamber 53, the water in the water supply pipe 4 can enter the opening of the treatment box 5 through the branch pipe 41 and then enter the first treatment chamber 53. The bottom end of the treatment box 5 is fixedly provided with a water inlet pipe 55. One end of the water inlet pipe 55 is equipped with a solenoid valve 56. By setting the water inlet pipe 55 and the solenoid valve 56, the solenoid valve 56 can control the opening and closing of the water inlet pipe 55. When the water inlet pipe 55 is in the open state, the water in the second treatment chamber 54 can flow into the domestic water tank 1, the industrial water tank 2 and the fire water tank 3 through the water inlet pipe 55.

[0035] In one possible implementation, a filtration mechanism 6 is provided in the first treatment chamber 53, and a stirring mechanism 8 is provided in the second treatment chamber 54. By providing the filtration mechanism 6, the incoming water can be filtered to prevent the presence of gravel and silt in the incoming water, thereby preventing gravel and silt from entering the domestic water tank 1, industrial water tank 2, and fire water tank 3, and thus reducing the maintenance frequency of the domestic water tank 1, industrial water tank 2, and fire water tank 3. By providing the stirring mechanism 8, when the water treatment agent is added to the second treatment chamber 54, the stirring mechanism 8 stirs the agent and water to treat acidic substances in the water and prevent the pipelines in the power plant from being corroded.

[0036] In one possible implementation, the filtration mechanism 6 includes a filter plate 61 and two trapezoidal hoppers 62. By configuring the filter plate 61 and trapezoidal hoppers 62, when water flows downwards in the branch pipe 41, the downward-flowing water enters the trapezoidal hoppers 62. When the trapezoidal hoppers 62 are flipped, the water inside can fall onto the filter plate 61. The filter plate 61 can filter the water, removing gravel and sand. The trapezoidal hoppers 62 can prevent a large amount of water from entering at once, controlling the amount of water entering at one time and improving the water filtration effect. The filter plate 61 is detachably installed at the bottom of the first processing chamber 53, and the filter plate 61 is located between the two... Below the trapezoidal bucket 62, a first rotating shaft 63 is rotatably installed inside the first processing chamber 53. A fixed roller 64 is fixedly installed on the first rotating shaft 63. Two fixed plates 65 are fixedly installed on the outer wall of the fixed roller 64. One side of the fixed plate 65 is fixedly connected to the bottom of the trapezoidal bucket 62. A servo motor 66 is fixedly installed on one side of the processing box 5. The drive output end of the servo motor 66 is fixedly connected to one end of the first rotating shaft 63. By turning on the servo motor 66, the drive shaft of the servo motor 66 can make the first rotating shaft 63 rotate. The first rotating shaft 63 can make the trapezoidal bucket 62 flip through the fixed roller 64 and the fixed plate 65.

[0037] In one possible implementation, a U-shaped support plate 67 and an L-shaped pressure plate 68 are fixedly provided on the bottom wall of the first processing chamber 53. Four L-shaped pressure plates 68 are provided, and the L-shaped pressure plates 68 are located above the U-shaped support plate 67. The filter plate 61 is movably inserted between the U-shaped support plate 67 and the L-shaped pressure plate 68. By setting the U-shaped support plate 67 and the L-shaped pressure plate 68, when the filter plate 61 is inserted between the U-shaped support plate 67 and the L-shaped pressure plate 68, the filter plate 61 can be fixed between the U-shaped support plate 67 and the L-shaped pressure plate 68. By pulling the filter plate 61 in the opposite direction, the filter plate 61 can be disassembled.

[0038] In one possible implementation, a cover plate 69 is detachably installed on one side of the treatment box 5. A sealing gasket 7 is fixedly installed on one side of the cover plate 69. The sealing gasket 7 is in movable contact with the side wall of the first treatment chamber 53. Two fixing bolts 71 are threadedly installed at both ends of the cover plate 69. One end of the fixing bolt 71 is threadedly connected to one side of the treatment box 5. By setting the cover plate 69 and fixing bolts 71, the cover plate 69 can be fixed to one side of the treatment box 5 by fixing bolts 71. When the cover plate 69 is removed, the filter plate 61 can be pulled out. By setting the sealing gasket 7, the sealing between the cover plate 69 and the treatment box 5 can be improved, preventing water from flowing out.

[0039] In one possible implementation, the stirring mechanism 8 includes a second rotating shaft 81, which is rotatably mounted on the inner wall of the second treatment chamber 54. A rotating roller 82 is fixedly mounted on the second rotating shaft 81, and a plurality of stirring blades 83 are fixedly mounted on the rotating roller 82. A dosing pipe 87 is fixedly mounted on the other side of the treatment chamber 5, and one end of the dosing pipe 87 is connected to the second treatment chamber 54. By providing the dosing pipe 87, it is convenient for operators to add water treatment agents into the second treatment chamber 54. By driving the second rotating shaft 81 to rotate, the second rotating shaft 81 can cause the stirring blades 83 to rotate through the rotating roller 82. The stirring blades 83 can stir the agents and water, so that the agents can quickly dissolve in the water and treat acidic substances in the water.

[0040] In one possible implementation, a transmission rod 84 is rotatably mounted on one side of the processing box 5. A first bevel gear 85 is fixedly provided at one end of the first rotating shaft 63 and one end of the transmission rod 84. The two first bevel gears 85 mesh with each other. A second bevel gear 86 is fixedly provided at the other end of the transmission rod 84 and one end of the second rotating shaft 81. The two second bevel gears 86 mesh with each other. When the first rotating shaft 63 rotates, the first rotating shaft 63 can cause the transmission rod 84 to rotate through the first bevel gear 85. The transmission rod 84 can cause the second rotating shaft 81 to rotate through the second bevel gear 86.

[0041] Working principle: When the power plant needs to use domestic water, industrial water and fire-fighting water, the water from the water source enters the domestic water tank 1, industrial water tank 2 and fire-fighting water tank 3 respectively through the water supply pipe 4 and three branch pipes 41.

[0042] During this process, water enters the trapezoidal hopper 62. When the upper trapezoidal hopper 62 is full of water, the operator turns on the servo motor 66. The drive shaft of the servo motor 66 causes the first rotating shaft 63 to rotate. The first rotating shaft 63 can rotate the two trapezoidal hoppers 62 through the fixed roller 64 and the fixed plate 65. The water in the upper trapezoidal hopper 62 flows into the filter plate 61, and the bottom trapezoidal hopper 62 rotates upward to a horizontal state to continue to receive the water flowing downward from the branch pipe 41 and into the filter plate 61. The filter plate 61 filters the gravel and silt in the water to prevent the gravel and silt in the water from entering the domestic water tank 1, industrial water tank 2 and fire water tank 3, thereby reducing the maintenance frequency of the domestic water tank 1, industrial water tank 2 and fire water tank 3. At the same time, the alternation of the two trapezoidal hoppers 62 prevents a large amount of water from entering at once, controls the amount of water entering at one time, and thus improves the water filtration effect.

[0043] Meanwhile, the operator adds the water treatment agent to the second treatment chamber 54 through the dosing pipe 87. The first rotating shaft 63 rotates the transmission rod 84 through two first bevel gears 85. The transmission rod 84 rotates the second rotating shaft 81 through two second bevel gears 86. The second rotating shaft 81 rotates the stirring blade 83 through the rotating roller 82. The stirring blade 83 stirs the agent and water, so that the agent dissolves quickly in the water, treats the acidic substances in the water, avoids corrosion of the pipelines in the power plant, and thus reduces the maintenance frequency and replacement cost of the power plant pipelines.
