Abstract
Description
Technical Field
[0001] This invention belongs to the field of zero-carbon energy-saving booster for secondary water supply, and in particular, it is a booster that uses the residual pressure of the pipeline network to achieve zero-carbon booster water supply. Background Technology
[0002] With increasing urban building density and rising living standards, water supply loads are growing, while the upgrading and renovation of municipal pipe networks are lagging behind, leading to a decrease in the service water pressure (hereinafter referred to as residual pressure). In older residential areas directly supplied by the municipal government, the problem of insufficient water pressure is particularly prominent, forcing these areas to switch from the original direct municipal supply method to a system of "low-level water tanks (pools) + variable frequency pumps" for secondary regulation and pressurization. When water from the municipal pipe network is introduced into the water tank, the original residual pressure is completely released to zero, failing to be effectively utilized and being directly wasted. Furthermore, during periods of low or zero water flow, pumps often operate inefficiently or even ineffectively. For example, in one residential area, during the low-flow period at night (1:00 AM to 5:00 AM), water consumption accounted for only 0.8% of the total daily amount, while pump energy consumption accounted for 11.1% of the total daily energy consumption.
[0003] For the widely used "low-level water tank (pool) + frequency converter" regulating and pressurizing secondary water supply systems in buildings and communities, a zero-carbon booster that requires no external power is urgently needed during low-flow water usage periods at night. This would ensure a stable water supply for users while avoiding frequent pump start-stop cycles, thus reducing energy consumption and carbon emissions. During peak water usage periods, as long as the water tank has not reached its maximum level, the booster can work in conjunction with the pump unit, reducing pump operating energy consumption. Therefore, designing a booster that utilizes residual pressure in the pipeline network to achieve zero-carbon pressurized water supply is essential. Summary of the Invention
[0004] The purpose of this application is to provide a booster that utilizes the residual pressure in the pipeline network to achieve zero-carbon boost water supply.
[0005] To achieve the above objectives, this application provides the following technical solution: a booster for zero-carbon pressurized water supply that utilizes residual pressure in a pipeline network for coordinated transmission, comprising a pipeline consisting of two symmetrical inlet pipes, wherein the pipeline has one inlet and two outlets: an inlet for water from the municipal water supply network, an outlet for water to a low-level water tank (pool), and an outlet for water to the user. It also includes two symmetrical cavities, each with a partition that divides the two cavities into four chambers: A, B, C, and D. A linkage rod is horizontally movable inside each cavity and is fixedly connected to the partition. The linkage rod has a key, and the reciprocating motion of the key triggers the commutator to achieve an automatic hydraulic switching function that connects to the municipal water supply network or discharges water into the water tank. The commutator has five interfaces: interface one connecting to the inlet pipe, interface two connecting to chamber C, interface three connecting to chamber D, and interface four connecting to the water tank. The commutator contains a component capable of horizontal reciprocating movement, consisting of a left-end short pipe, a middle connecting rod, and a right-end short pipe. A spring on the inner stop block of the circular ring welded to the middle connecting rod engages with a key on the linkage rod, enabling the linkage rod to reciprocate horizontally, thus achieving the alternating opening and closing function of water entering the municipal water supply network and draining into the water tank. The commutator has symmetrical pressure caps for alternately closing or opening the channels between chambers C and D and the water tank or inlet pipe, achieving hydraulically controlled flow direction switching. The inlet pipe is equipped with a left one-way valve and a right one-way valve.
[0006] Interface five of chamber A is connected to the pipeline, interface six of chamber C is connected to interface two, interface seven of chamber B is connected to the pipeline, and interface eight of chamber D is connected to interface two.
[0007] Both the right side of the left short tube and the left side of the right short tube are perforated, with an opening rate of 50% for both. The right end of the left short tube and the left end of the right short tube are closed.
[0008] The linkage rod passes through four mechanical seal points from left to right.
[0009] The separator is a diaphragm with a pressure plate or a piston cylinder.
[0010] Based on Pascal's law, by utilizing the residual pressure of the municipal water supply network to fill chambers A and D with water, the separator is driven to move horizontally to the right to perform work, thereby pressurizing and supplying water to chamber B and draining water from chamber C into the water tank. When the municipal water supply network fills chambers C and B with water, the separator is driven to move horizontally to the left to pressurize and supply water to chamber A and drain water from chamber D into the water tank.
[0011] The booster of this invention makes full use of the waste residual pressure of the low-level water tank (pool) in the secondary water supply, and provides a zero-carbon booster that utilizes the residual pressure of the municipal water network and has a reasonable structural design and stable and reliable performance. It taps into the water energy of the municipal water network to do work, and uses the working water after the work is done in the water tank for water storage (water tank replenishment), so as to achieve boosted water supply to users without consuming external power. It protects the water pump from inefficient or ineffective operation and frequent start-stop during off-peak water use periods, thus saving energy and reducing consumption.
[0012] In summary, the technical effects and advantages of this invention are as follows: The booster of this invention is suitable for secondary water supply in buildings and communities with low-level water tanks (pools), achieving energy saving and consumption reduction, especially green water supply with no power consumption during low-flow periods at night. It makes full use of the municipal residual pressure that was previously wasted during the water tank filling process, and achieves pressure boosting and water supply by superimposing pressure energy. The water after the work is done is sent to the water tank for storage, with no waste of water resources and efficient use of water resources and water energy. The booster enables continuous water supply during low-flow periods at night, avoiding frequent start-stop and inefficient operation of water pumps during this period, achieving energy saving and pump protection.

Detailed Implementation
[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.
[0016] like Figures 1-7 As shown, this booster for zero-carbon pressurized water supply utilizes the residual pressure of the pipeline network for coordinated transmission. It includes a pipeline consisting of two symmetrical inlet pipes 1-1 and 1-2. The pipeline has one inlet and two outlets: inlet 2 for water from the municipal water supply network, outlet 3 for water to the low-level water tank (pool), and outlet 4 for water to the user. In practice, the low-level water tank can also be a low-level water pool. It also includes two symmetrical cavities 5-1 and 5-2. Cavities 5-1 and 5-2 are equipped with partitions 6-1 and 6-2, which divide them into chamber A, chamber B, chamber C and chamber D. A linkage rod 7 is horizontally movable between cavities 5-1 and 5-2. The linkage rod 7 is fixedly connected to the partitions 6-1 and 6-2. There is a key 8 on the linkage rod 7. The reciprocating motion of the key 9 triggers the reversing device 10 to realize the automatic hydraulic switching function of connecting to the municipal water supply network or discharging water to the water tank. The commutator 10 has five interfaces: interfaces 11-1 and 11-2 connecting to the inlet pipes 1-1 and 1-2, interface 12 connecting to chamber C, interface 13 connecting to chamber D, and interface 14 connecting to the water tank. The commutator 10 contains a component capable of horizontal reciprocating movement. This component consists of three sections: a left-end short pipe 18, a middle connecting rod 19, and a right-end short pipe 20. Specifically, the component is dumbbell-shaped. The middle connecting rod 19 consists of multiple solid stainless steel rods with a diameter of 10 mm. The springs 21-1 and 21-2 on the inner ring stops 20-1 and 20-2 welded to the middle connecting rod 19 cooperate with the key 8 on the linkage rod 7. In this embodiment, the middle connecting rod 19... The springs 21-1 and 21-2 on the welded inner ring blocks 20-1 and 20-2, which act as buffers, cooperate with the key 8 on the linkage rod 7. Specifically, the linkage rod 7 has a horizontal positioning sealing bushing, and the key 8 on the linkage rod 7 contacts the inner ring blocks 20-1 and 20-2 on the commutator 10 to generate a linkage transmission function, realizing the left and right horizontal reciprocating motion of the linkage rod 7, thereby realizing the left and right alternating opening and closing function of water inlet to the municipal water supply network and water outlet to the water tank; the commutator 10 has left and right symmetrical pressure caps 22-1 and 22-2, which are used to alternately close or open the channels between chambers C and D and the water tank or inlet pipes 1-1 and 1-2, realizing hydraulic self-controlled switching of flow direction; Left check valves 23-1, 23-2, and 23-3 are installed on inlet pipe 1-1, and right check valves 24-1, 24-2, and 24-3 are installed on inlet pipe 1-2.
[0017] Using this structure, the horizontal reciprocating force transmission of the separators 6-1 and 6-2 and the linkage 7 causes a change in the cavity volume, realizing the alternating opening and closing of the commutator 10. Under the action of pressure difference, six valves, namely the left check valves 23-1, 23-2, and 23-3 and the right check valves 24-1, 24-2, and 24-3, alternately open and close. When both chambers A and D are simultaneously filled with water by the residual pressure of the municipal pipe network, the linkage 7 moves to the right, and the left check valve 23-2 and the right check valve 24-1, 24-2, and 24-3 open and close alternately. 1. When 24-3 is opened, the left check valves 23-1 and 23-3 and the right check valve 24-2 are closed, forming a pressurized water supply to chamber B while draining water from chamber C into the water tank. Similarly, when switching to chambers B and C being filled with water by the residual pressure of the municipal pipe network at the same time, the linkage rod 7 moves to the left, the left check valves 23-1 and 23-3 and the right check valve 24-2 are opened, and the left check valve 23-2 and the right check valves 24-1 and 24-3 are closed, forming a pressurized water supply to chamber A while draining water from chamber D into the water tank.
[0018] When chamber A is filled with water and chamber C is drained, the filling of chamber D and pressurization of chamber B are precisely synchronized. Conversely, when chamber B is filled with water and chamber D is drained, the filling of chamber C and pressurization of chamber A are precisely synchronized. This alternating operation achieves continuous pressurization and water draining into the water tank. This results in continuous pressurization for users and continuous replenishment of the water tank, achieving zero-carbon pressurization and water supply. Energy-dissipating water is replenished into the low-level water tank, practicing carbon emission reduction in the secondary water supply industry and serving the "dual-carbon" strategy of the water steward.
[0019] Interface 5 25 of chamber A is connected to pipe 1-1; interface 6 26 of chamber C is connected to interface 2 12; interface 7 27 of chamber B is connected to pipe 1-2; and interface 8 28 of chamber D is connected to interface 2 12.
[0020] Both the right side of the left short pipe 18 and the left side of the right short pipe 20 are perforated, with an opening rate of 50% for radial water passage; the right end of the left short pipe 18 and the left end of the right short pipe 20 are closed.
[0021] The linkage rod 7 passes through four mechanical seal points 29-1, 29-2, 29-3, and 29-4 from left to right.
[0022] Separators 6-1 and 6-2 are diaphragms or piston cylinders with pressure plates.
[0023] Under the pressure difference between the water tank side and the municipal water supply side, and with the switching action of the reversing device 10, the corresponding valves automatically open and close, filling chambers A and D with water. Under the residual pressure of the pipeline network, the thrust generated by the two chambers on the separators 6-1 and 6-2 is superimposed, squeezing chambers C and B to the right through the linkage rod 7. The water in chamber C easily drains into the unpressurized low-level water tank, while the water in chamber B is pressurized by the thrust and supplied to the user. When the key 8 of the linkage rod 7 moves to the right and contacts the inner stop block 20-2 on the right side of the commutator 10, the opening and closing of chambers C and D with the water tank or municipal water supply is switched. Municipal water supply fills chambers C and B, and the thrust is superimposed to squeeze chambers A and D. Water in chamber D is discharged into the water tank, and water in chamber A is pressurized and supplied to the user. When the linkage rod 7 moves to the left and the key 8 contacts the inner stop block 20-1 on the left side, the opening and closing of chambers C and D with the water tank or municipal water supply is switched again. This cycle repeats, so that two chambers (chambers A and D or chambers C and B) can simultaneously receive municipal water (fill water), while the other two chambers (chambers C and B or chambers A and D) can supply water on one side and discharge water on the other.
[0024] When the separators 6-1 and 6-2 are diaphragms with pressure plates, it is a diaphragm booster; this is the mode of boosting pressure by 1 time (ignoring friction loss), and the boosting ratio is 2. 1m³ of municipal water enters the diaphragm booster, 0.5m³ of water is boosted by 1 time for supply to the user, and 0.5m³ of water (after water energy utilization and energy dissipation) enters the water tank.
[0025] Diaphragm turbocharger: Ignoring the frictional resistance between the linkage rod and the sealing ring, the horizontal force balance analysis of the linkage rod is as follows: F A +F D =F C +F B Wherein: F A =p A S A F B =p B S B F C =p C S C F D =p D S D If the residual pressure in the municipal pipeline is p0, then p A =p D =p0, C cavity connected to water tank: p C ≈0 The area ratio is set as follows:
[0026] Then: p A S A + p D S D = p C S C +p B S B p B S B = p A SA +p D S D =2p A S A
[0027] The boost ratio is 2, that is
[0028] Furthermore, a piston cylinder is used instead of a diaphragm, which is called a piston cylinder type booster. The piston cylinder has unequal areas at the front and back. The diameters of chambers A and B are equal, and the diameters of chambers C and D are equal. The diameter of chamber A is smaller than that of chamber C. The ratio k between the two diameters depends on the designed boosting factor n. By utilizing the principle of unequal areas at the front and back of the piston cylinder, a pressure factor of more than 2 can be achieved. Furthermore, it can be used in conjunction with a pressure tank to achieve uninterrupted and stable water supply.
[0029] When the boost ratio exceeds 2, a piston-type booster with unequal areas on both sides must be used, such as... Figure 4 As shown; ignoring the frictional resistance between the linkage rod and the sealing ring, the horizontal force balance analysis of the piston cylinder is as follows: F A +F D =F C +F B Wherein: F A =p A S A F B =p B S B F C =p C S C F D =p D S D If the residual pressure in the municipal pipeline is p0, then p A =p D =p0, C cavity connected to water tank: p C ≈0 The area ratio is set as follows:
[0030] Then: p A S A + p D S D = p C S C +p B S B p B S B = p A S A +pD S D
[0031] When the boost factor is n, that is
[0032] but
[0033] Taking a pressure boosting ratio of 3 as an example, that is, the municipal pipeline residual pressure is 0.2 MPa, and the user's pipeline required pressure is 0.6 MPa, the pressure ratio is 1:3. When the pressure boosting ratio n=3, the piston cylinder area ratio k=2.62, and the piston cylinder diameter ratio is... When 3.62 m³ of municipal water (0.2 MPa) enters the booster, 1 m 3 (0.6MPa) water supply to users, 2.62m 3 Water enters the water tank.
[0034] Based on Pascal's law, by utilizing the residual pressure of the municipal water supply network to fill chambers A and D with water, the separators 6-1 and 6-2 are driven to move horizontally to the right to perform work, thereby pressurizing and supplying water to chamber B and draining water from chamber C into the water tank. When the municipal water supply network fills chambers C and B with water, the separators 6-1 and 6-2 are driven to move horizontally to the left to pressurize and supply water to chamber A and drain water from chamber D into the water tank.
[0035] Based on Pascal's Law, the turbocharger fully utilizes the energy of municipal surplus pressure to do work, driving the diaphragm or piston cylinder inside the turbocharger to move reciprocally left and right. A diaphragm turbocharger has a boost ratio of 2. If the boost ratio is greater than 2, a piston turbocharger with unequal surface areas on both sides must be used. Figure 4 If the outer surface area of the piston cylinder is k times the inner surface area, then municipal water fills chambers A and D. Hydraulic work will generate a pressure n times the municipal residual pressure in chamber B, achieving pressurized water supply without consuming electricity. The residual pressure is then used to drive the piston in the reverse stroke, injecting the working water from that chamber into the water tank. Although the pressure in the left chamber during the second stroke of the piston cylinder is the municipal residual pressure... times, k times superposition The functional relationship between the boost factor n and the design boost ratio is as follows: . Then the ratio of the inner and outer diameters of the piston cylinder is .
[0036] The working principle of this invention is to generate a left-right pressure difference by using the unequal area of the piston cylinder. The piston cylinder and linkage rod 7 move left and right, which both pressurizes water supply and dissipates energy to replenish water into the tank. This causes no impact on the float ball inside the water tank and reduces water intake noise. The six valves and reversing structure automatically close alternately, injecting water into different chambers. At the same time, pressurizing water supply and replenishing water into the tank alternately to achieve zero-carbon pressurized water supply and pump protection.
[0037] In practice, this booster is installed in a secondary water supply pump room equipped with a low-level water tank (pool). It uses the municipal residual pressure to work on the sliding components of the piston-type booster or diaphragm-type booster, achieving a cyclical left and right stroke, automatically and smoothly continuously boosting water supply and draining water to the water tank, so as to achieve zero-carbon water supply and pump protection.
[0038] See Figure 7 The existing "low-level water tank + variable frequency pump" secondary water supply system includes: low-level water tank inlet pipe 101, original float valve 102, low-level water tank 103, variable frequency pump 104, pressure tank 105, user pipeline network 106, pressure sensor 107, and electrical control cabinet 108. Adding this "booster" requires the installation of three additional pipe sections: booster inlet pipe section A, booster outlet pipe section B, and booster outlet pipe section C. The first pipe section A is installed by opening a branch port on the pipe section from the municipal water supply network into the water tank, and installing the booster inlet pipe section A to connect the municipal tap water supply. Figure 1 The inlet of the booster is 2; the second pipe section B is: starting from the outlet of the booster 4, it is connected to the pressure pipe of the variable frequency pump 104; the third pipe section C is: from the outlet of the booster 3 to the water tank inlet.
[0039] When the water tank reaches its maximum level, it will be unable to accommodate the booster's replenishment water, and the booster should stop operating. Otherwise, the water tank will overflow. In this case, it is necessary to switch to the variable frequency pump 104 water supply mode. The variable frequency pump 104 draws water from the water tank, pressurizes it, and supplies water to the user. After the water level in the tank drops, the booster can restart. The booster can replace the inefficient operation of the water pump during low-flow periods at night, while utilizing the pressure tank 105 to stabilize the pressure and achieve continuous constant pressure water supply.
[0040] Taking a pressure boosting ratio of 2.5 as an example, that is, the municipal pipeline residual pressure is 0.2 MPa, and the user's pipeline required pressure is 0.5 MPa, the pressure ratio is 1:2.5. Therefore, the area of the left chamber of the booster piston cylinder is [amount missing] times the area of the right end. For example, a booster pump draws 3 m³ (0.2 MPa) of water from the municipal water supply network, outputs 1 m³ (0.5 MPa) to the user, and stores the remaining 2 m³ in a water tank. The working water in the tank must eventually be pressurized by a variable frequency pump and supplied to the user's network to free up the tank's capacity to receive the unpressurized working water discharged from the booster pump. If the secondary water supply pump station supplies 120 m³ of water per day, the booster pump uses the residual pressure of the municipal water supply network to pressurize and supply 40 m³ of water. The total amount of water discharged into the water tank by the booster pump is twice the supply amount: 2 × 40 = 80 m³. The 80 m³ of unpressurized water entering the tank needs to be pressurized by the variable frequency pump unit and supplied to the user's network. The booster pump's energy saving rate is about 33.3%. Therefore, the booster pump cannot completely replace the water pump unit, but works in conjunction with it to play a certain role in reducing carbon emissions and energy consumption, and to a certain extent, it replaces the work of the water pump.
[0041] In summary, the booster of this invention must work in conjunction with the low-level water tank and variable frequency pump in the original pump room. The water tank receives the influent from the booster's working water. When the water tank reaches its maximum level, the booster stops working, and the variable frequency pump immediately starts, drawing water from the tank and pressurizing it to supply the user, thus freeing up the water tank's capacity to create conditions for the booster to operate. The working water stored in the tank that has lost its residual pressure is not contaminated and must be drawn out by the variable frequency pump and pressurized to supply the user's pipeline network.
