Abstract
Description
Technical Field
[0001] This invention relates to the field of cooling system water replenishment technology, specifically to an optimized and modified system for direct water replenishment pipelines from variable porosity filter effluent to circulating water tank. Background Technology
[0002] Variable porosity filters are mainly composed of filter media of different particle sizes mixed in a certain proportion, with the larger proportion of coarser particle size filter media. The small particle size filter media is dispersed in the gaps between the coarse particle size filter media to form a "variable porosity" structure, which filters particulate impurities in the liquid.
[0003] When the unit is operating, water needs to be drawn from the circulating water tank to cool it down. The water in the circulating water tank gradually decreases due to evaporation from heat. To ensure sufficient water in the circulating water tank, it needs to be replenished periodically. In existing technology, water filtered by a variable porosity filter is discharged into an industrial water tank, and then pressurized by an industrial water pump to replenish the circulating water tank. Replenishing water by pressurizing with an industrial water pump consumes a significant amount of electricity, which is not energy-efficient or environmentally friendly. Therefore, we propose a pipeline optimization and renovation system that utilizes the height difference between the circulating water tank and the variable porosity filter tank for direct water replenishment. This system uses high potential energy to replace electrical energy for water replenishment, thereby saving electrical energy. Summary of the Invention
[0004] The purpose of this invention is to provide an optimized and modified system for the direct water supply pipeline from the effluent of a variable porosity filter to a circulating water tank, in order to solve the problem mentioned in the background art that the circulating water tank needs to be pressurized by an industrial water pump when replenishing water.
[0005] To achieve the above objectives, the present invention provides the following technical solution: an optimization and renovation system for the direct water supply pipeline from the effluent of a variable porosity filter to the circulating water tank, comprising: The variable porosity filter has a clarifier connected to its outlet. The circulating water tank is excavated below ground level; a water supply pipe is connected between the inlet of the circulating water tank and the outlet of the clarification tank, and there is a height difference between the two. The water in the clarification tank can flow into the circulating water tank under the action of gravity. The detection valve, with its valve body installed on the water supply pipe, is used to control the opening and closing of the water circuit. The detection end of the detection valve is connected to the circulating water tank to detect the water level. When the water level is lower than the water consumption threshold, the water supply pipe is opened; when the water level is higher than the safety threshold, the water supply pipe is closed.
[0006] Preferably, the clarification tank is added to the outlet end of the variable porosity filter, and the height of the outlet end of the clarification tank is not lower than the height of the outlet end of the variable porosity filter.
[0007] Preferably, the clarification tank includes two or more compartments, with the inlet ends of each compartment connected in series, and the inlet and outlet ends of the same compartment being staggered in height.
[0008] Preferably, the number of circulating water pools is at least two; each connection section between the water supply pipe and each circulating water pool is equipped with a manual valve, which is connected to the inlet end of the detection valve through the water supply pipe.
[0009] Preferably, the detection end includes: A fixed housing is fixedly installed; an installation groove is provided on the inner side of the fixed housing, and a gear rack and a gear that mesh with each other are movably installed on the inner side of the installation groove; the valve stem of the valve body passes through the fixed housing and is connected to the gear. A support plate is fixedly installed; a lever is hinged to the support plate, and a first connecting rod and a second connecting rod are respectively hinged to the two ends of the lever; the other end of the first connecting rod is hinged to a gear rack; the other end of the second connecting rod is hinged to a buoyancy column.
[0010] Preferably, the gear rack has limit blocks at both the upper and lower ends on the tooth side, and the teeth of the gear rack are located between the two limit blocks.
[0011] Preferably, a guide tube is sleeved on the outer side of the buoyancy column, and a drain valve is connected to the lower end of the guide tube; the guide tube is connected to a reducer pipe through a tee, and a water pipe is connected to the other end of the reducer pipe, which is connected to the inlet of the circulating water tank.
[0012] Compared with the prior art, the beneficial effects of the present invention are: 1) Currently, the circulating water tank requires a 30KW industrial water pump to operate at 60% load for 14 hours a day for water replenishment, consuming 91,980 kWh of electricity per year. This invention utilizes the static pressure difference of the variable porosity filter to directly replenish the circulating water tank, avoiding the need to turn on the industrial water pump, and saving 91,980 kWh of electricity per year.
[0013] 2) This invention uses a detection valve to detect the water level in the circulating water tank, and then uses the detection valve to control the flow rate of water entering the circulating water tank, so as to avoid the water level in the circulating water tank being too high or too low.

Detailed Implementation
[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.
[0018] Example 1:
[0019] Please see Figure 2-6 This invention provides a technical solution: an optimization and modification system for the direct water supply pipeline from the effluent of a variable porosity filter to a circulating water tank, comprising: a variable porosity filter 21, a circulating water tank 10, and a detection valve. The water filtered by the variable porosity filter 21 is directly discharged into the circulating water tank 10. Then, the detection valve is used to check whether there is too much or too little water in the circulating water tank 10. When there is too much water, the flow rate of the water passing through is reduced, thus reducing the amount of water entering the circulating water tank 10. When there is too little water in the circulating water tank 10, the flow rate of the water passing through is increased, thus increasing the amount of water entering the circulating water tank 10.
[0020] In the existing technology, the variable porosity filter and circulating water tank connection system includes three variable porosity filters 21 and two circulating water tanks 10. The dimensions of each variable porosity filter 21 are 3.5m * 3.4m * 5.3m (length * width * height), and the operating water level is between 4.3m and 5m. The outlet end of each variable porosity filter 21 is connected to an outlet header pipe 0.5m above ground. A DN250 butterfly valve is installed on the outlet header pipe, and the other end of the outlet header pipe is connected to an industrial water tank. Water from the variable porosity filters is discharged into the industrial water tank. Then, the water is pressurized by an industrial water pump and used to replenish the circulating water tank 10. (See...) Figure 1 ) The filter 21 is improved by adding a clarifier 22 at its outlet end and connecting the outlet end of the filter 21 to the inlet end of the clarifier 22. The clarifier 22 includes two or more compartments, which are sequentially connected between the inlet and outlet ends of the clarifier 22, with the inlet end of one compartment connected to the inlet end of another compartment. The inlet and outlet ends of the same compartment are staggered in height; for example, the outlet end of the compartment is above the left end of the compartment, and the inlet end is below the right end of the compartment. This staggered arrangement of the inlet and outlet ends allows the water entering the clarifier 22 to settle, facilitating the sedimentation of residual impurities in the clarifier 22 and enabling the water to settle and clarify. The outlet of the clarifier 22 is located at least 0.8m above the ground to ensure that there is a drop between the bottom of the clarifier 22 and the outlet, thus preventing impurities settled in the clarifier 22 from being discharged from the outlet.
[0021] The circulating water tank 10 is located below 0m above ground level. In summer, when the water temperature is high, geothermal energy can be used to lower the water temperature in the circulating water tank 10, accelerating heat dissipation. The inlet of the circulating water tank 10 is rerouted to connect with the clarifier 22; the outlet of the clarifier 22 is connected to the inlet of the circulating water tank 10 via a water supply pipe 31. The clarifier 22 is at the same height as the variable porosity filter 21, and its operating water level is between 4.3m and 5m. This creates a height difference between the clarifier 22 and the circulating water tank 10, allowing water in the clarifier 22 to flow into the circulating water tank 10 under gravitational potential energy.
[0022] The detection valve is used to control the water level in the circulating water tank 10 to ensure that there is no problem of excessive or insufficient water flow. The detection valve includes a valve body 33 and a detection end 34. The valve body 33 is installed on the water supply pipe 31. Water entering the circulating water tank 10 from the clarification tank 22 passes through the valve body 33. The valve body 33 is a valve that allows the flow of liquid to be adjusted by rotating the valve stem, such as a ball valve or butterfly valve. The detection end 34 of the detection valve is connected to the water inlet of the circulating water tank 10. The water inlet of the circulating water tank 10 is equipped with a filter screen to filter and prevent backflow of impurities in the circulating water tank 10. The detection end 34 is used to detect the water level. A water level sensor can be used to collect the liquid level data in the circulating water tank 10 to analyze the water level. When the water level in the circulating water tank 10 is below the water consumption threshold (the water volume in the circulating water tank 10 is about to be insufficient), the control end of the detection valve opens the valve body 33, allowing water to flow smoothly into the circulating water tank 10 through the water supply pipe 31. When the water level is above the safety threshold (the water volume in the circulating water tank 10 is about to overflow), the control end of the detection valve closes the valve body 33, preventing water from flowing into the circulating water tank 10 through the water supply pipe 31. A motor can be installed to act as the control end of the detection valve. The output shaft of the motor is connected to the valve stem of the valve body 33 after being reduced in speed. The motor drives the valve stem to rotate, thereby controlling the opening and closing of the valve body 33.
[0023] There are at least two circulating water tanks 10; each circulating water tank 10 is equipped with a detection valve and a manual valve 32 at the connection point between itself and the water supply pipe 31. Each circulating water tank 10 is equipped with a detection valve, allowing each circulating water tank 10 to be independently controlled for water supply, ensuring water supply safety. The manual valve 32 is connected to the inlet end of the detection valve through the water supply pipe 31. The manual valve 32 is used to manually shut off the water supply, facilitating the replacement and maintenance of the detection valve.
[0024] Example 2:
[0025] Please see Figure 3-6 The present invention provides a technical solution: an optimization and renovation system for the direct water supply pipeline from the effluent of the variable porosity filter to the circulating water tank. Based on the first embodiment, the detection end 34 includes: a buoyancy column 341, a first connecting rod 342, a lever 343, a support plate 344, a second connecting rod 345, a gear rack 346, a gear 347, and a fixed shell 348.
[0026] The fixed housing 348 is fixedly installed on the surrounding wall or pillar. The inner side of the fixed housing 348 has an installation groove. The gear 347 is movably installed on the inner side of the installation groove, and the gear rack 346 is slidably installed. The valve stem of the valve body 33 passes through the fixed housing 348 and is connected to the gear 347. The gear 347 is driven to rotate by the sliding of the gear rack 346. The rotation of the gear 347 drives the valve stem of the valve body 33 to rotate.
[0027] The support plate 344 is fixedly installed on the surrounding wall or pillar by a bracket. A lever 343 is hinged to the support plate 344. A first connecting rod 342 and a second connecting rod 345 are respectively hinged to the two ends of the lever 343. The other end of the first connecting rod 342 is hinged to the gear rack 346. The other end of the second connecting rod 345 is hinged to the buoyancy column 341. When the water level rises, the buoyancy column 341 moves upward and drives the gear rack 346 to move downward through the lever 343, thereby closing the valve body 33. When the water level falls, the buoyancy column 341 moves downward and drives the gear rack 346 to move upward through the lever 343, thereby opening the valve body 33.
[0028] By turning the valve stem to open and close the valve body 33, the flow rate through the valve body 33 can be controlled by the position and height of the buoyancy column 341 (the water level in the circulating water tank 10); through flow control, the water consumption and water replenishment in the circulating water tank 10 are kept in dynamic balance, thereby enabling better water replenishment.
[0029] The gear rack 346 has a limit block 3461 fixedly connected to both the upper and lower ends of the tooth side, and the teeth of the gear rack 346 are located between the limit blocks 3461 on both sides; the limit block 3461 fits against the inner wall of the mounting groove of the fixed shell 348 to prevent the teeth from directly rubbing against the inner wall of the mounting groove.
[0030] To enhance the stability of the buoyancy column 341, a guide pipe 362 is fitted around its outer side. The guide pipe 362 can be fixed to a wall or column in the external environment using pipe clamps to improve stability. The upper end of the guide pipe 362 is higher than the upper end of the circulating water tank 10, meaning that water in the circulating water tank 10 will not drain out from the upper end of the guide pipe 362. The guide pipe 362 is connected to a reducer pipe 361 via a tee. The other end of the reducer pipe 361 is connected to a water pipe 35, and the other end of the water pipe 35 is connected to the water inlet of the circulating water tank 10. The orifice of the guide pipe 362 is larger than that of the water pipe 35. By increasing the pipe diameter through the reducer pipe 361, the water flow velocity slows down after entering the guide pipe 362 from the water pipe 35, which is beneficial to the stability of the buoyancy column 341 inside the guide pipe 362. The lower end of the guide pipe 362 is connected to a drain valve 363. When the flow rate slows down, the particles in the water will settle into the drain valve 363. The drain valve 363 is opened periodically to discharge the particles to avoid excessive accumulation of particles.
