Description

Technical Field

[0001] This utility model relates to the industrial field of thermal power plants, and in particular to a device for recycling cooling water in thermal power plants. Background Technology

[0002] The thermal power plant industry primarily involves a series of industrial activities related to thermal power generation. In this field, the chemical energy of fossil fuels such as coal, oil, or natural gas is converted into thermal energy through combustion. High-temperature, high-pressure steam is generated using equipment such as boilers, which drives a steam turbine to rotate, thereby powering a generator to produce electricity. The power generation process involves many key stages and systems. An industrial cooling water circulation system is a crucial component, used to cool the steam turbine and other equipment, ensuring their normal operation. In addition, it includes numerous complex and interconnected subsystems such as fuel delivery and processing systems, combustion systems, steam generation and transmission systems, and electrical systems.

[0003] Current cooling water circulation devices have low utilization rates of heat in cooling water, often discarding the heat, resulting in low energy efficiency. In addition, the filters used to remove impurities from the cooling water in current cooling water circulation devices are inconvenient to disassemble, making it time-consuming and labor-intensive for staff to replace them, thus resulting in low efficiency.

[0004] In response to this technical problem, this application proposes a device for recycling industrial cooling water in thermal power plants. Utility Model Content

The device aims to utilize the heat in the cooling water, improve resource utilization, and facilitate the installation and disassembly of the filter screen, thereby increasing the efficiency of filter screen replacement by staff.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A cooling water recycling device for thermal power plants includes a water tank for storing cooling water. A partition is fixedly connected to the middle of the tank's interior to divide it into two parts. A heat exchange tank is located on the right side of the tank, and a heat exchange assembly is installed inside the tank to transfer heat from the cooling water to other fluids entering the tank. Filter screens for filtering impurities in the cooling water are connected to both sides of the tank's bottom via snap-fit ​​assemblies, allowing the filter screens to be removed from the tank. A second water pump is installed on the bottom right side of the tank, and a first pipe is fixedly connected to one side of the second water pump. Second fixing plates are fixedly connected to the top of the partition and the right side of the top of the tank.

[0008] Furthermore, the heat exchange assembly includes a water inlet pipe fixedly connected to the bottom side of the outer wall of the heat exchange tank, and a water outlet pipe fixedly connected to the top side of the outer wall of the heat exchange tank.

[0009] Furthermore, a first water pump is installed on the left side of the outer wall of the water tank. The first water pump and the heat exchange tank are connected by a heat exchange pipe, and the middle end of the heat exchange pipe is fixedly connected to the inside of the heat exchange tank.

[0010] Furthermore, a first fixing plate is fixedly connected to the top side of the partition and the right side of the top side of the water tank. The top end of the first fixing plate is fixedly connected to the outer wall of the heat exchange tube, and one end of the heat exchange tube is located on the right side of the partition.

[0011] Furthermore, the buckle assembly includes two grooves on the left and right sides of the bottom of the water tank, two sliders are slidably connected inside the grooves, and a rod is fixedly connected between the upper and lower sliders, with one end of the rod inserted into the inside of the filter screen.

[0012] Furthermore, one end of the insertion rod is rotatably connected to a ring, the outer wall of the ring is fixedly connected to a limiting rod, a limiting groove is formed on the bottom side of the groove, and the limiting rod is engaged in the limiting groove.

[0013] Furthermore, a baffle is slidably connected to the top side of the groove, and the bottom end of the baffle is inserted into the inside of the limiting groove. The baffle is located on one side of the limiting rod.

[0014] Furthermore, one end of both the first and second pipes is connected to equipment that needs to be cooled, and multiple condenser pipes for accelerating the cooling of the water are fixedly connected to the right side of the inner wall of the water tank.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, cooling water is transported to the heat exchange tank through a heat exchange tube and a first water pump. Then, water or other fluids are transported into and out of the heat exchange tank through an inlet pipe and an outlet pipe, so that the cooling water heats the water or other fluids, thereby utilizing the heat in the cooling water and improving resource utilization.

[0017] 2. In this utility model, the filter screen is fixed by inserting the rod into it, and the rod cannot be removed from the filter screen by engaging the limiting rod into the limiting groove.

The cooling water in the water tank 6 is transported back to the water tank 6. A water inlet pipe 2 is fixedly connected to the bottom side of the outer wall of the heat exchange tank 3, and a water outlet pipe 1 is fixedly connected to the top side of the outer wall of the heat exchange tank 3. Water or other fluids are transported into and out of the heat exchange tank 3 through the water inlet pipe 2 and the water outlet pipe 1. A first water pump 5 is installed on the left side of the outer wall of the water tank 6. The first water pump 5 and the heat exchange tank 3 are connected through a heat exchange pipe 4. The middle end of the heat exchange pipe 4 is fixedly connected to the inside of the heat exchange tank 3. The first water pump 5 transports the cooling water in the water tank 6 into the heat exchange pipe 4, so that the cooling water exchanges heat with the water or fluid in the heat exchange tank 3 through the heat exchange pipe 4. A first fixing plate 8 is fixedly connected to the top side of the partition plate 7 and the top right side of the water tank 6. The top end of the first fixing plate 8 is fixedly connected to the outer wall of the heat exchange pipe 4. One end of the heat exchange pipe 4 is set on the right side of the partition plate 7. By setting one end of the heat exchange pipe 4 on the right side of the partition plate 7, the cooling water enters the right side of the water tank 6 after heat exchange.

[0026] Reference Figure 1 , Figure 3 and Figure 4Two grooves are formed on the left and right sides of the bottom of the water tank 6. Two sliders 15 are slidably connected inside the grooves. A rod 16 is fixedly connected between the upper and lower sliders 15. One end of the rod 16 is inserted into the filter screen 14. By inserting the rod 16 into the filter screen 14, the filter screen 14 is installed in the water tank 6. One end of the rod 16 is rotatably connected to a ring 17. A limit rod 18 is fixedly connected to the outer wall of the ring 17. A limit groove is formed on the bottom side of the groove. The limit rod 18 is engaged in the limit groove. The rod 16 is inserted into the limiting groove, preventing it from detaching from the filter screen 14. A baffle 19 is slidably connected to the top side of the groove, and the bottom end of the baffle 19 is inserted into the inside of the limiting groove. The baffle 19 is located on one side of the limiting rod 18. The limiting rod 18 is prevented from detaching from the limiting groove by inserting the baffle 19 into the limiting groove. One end of the first pipe 12 and the second pipe 13 are both externally connected to equipment that needs to be cooled. Multiple condenser pipes 9 are fixedly connected to the right side of the inner wall of the water tank 6 to accelerate the cooling of the cooling water. The cooling water is further cooled through the condenser pipes 9.

[0027] Working principle: First, the cooling water that has undergone cooling is transported to the left side of the water tank 6 through the second pipe 13. Then, the first water pump 5 is started to transport the cooling water to the heat exchange tube 4, and water or other fluids are transported into the heat exchange container 3 through the inlet pipe 2. At this time, the cooling water in the heat exchange tube 4 and the water or other fluids in the heat exchange container 3 will exchange heat, so that the cooling water heats the water or other fluids. Afterwards, the cooling water will flow to the right side of the water tank 6, while the water or other fluids will flow out of the heat exchange container 3 through the outlet pipe 1. The cooling water flowing into the right side of the water tank 6 will be further cooled by the condenser pipe 9. After initial cooling, the cooled water is then transported back to the equipment or nozzles that need cooling via the second water pump 11 and the first pipe 12 for recycling. During this process, the filter screen 14 filters out impurities in the cooling water to prevent them from flowing with the cooling water and affecting normal operation. When the filter screen 14 needs to be removed, simply pry the baffle 19 out of the limiting groove, rotate the ring 17 to disengage the limiting rod 18 from the limiting groove, and then pull the insertion rod 16 to disengage it from the filter screen 14. The filter screen 14 can then be removed from the water tank 6.
