Description

Technical Field

[0001] This invention relates to the field of accelerator technology, and more particularly to an accelerator circulating cooling water system. Background Technology

[0002] During operation, accelerator equipment generates a large amount of heat. As an auxiliary system for accelerator equipment, the accelerator cooling water system consists of heat exchange equipment, water flow regulation equipment, water pressure regulation equipment, water treatment equipment, the accelerator equipment to be cooled, and a piping system. Water directly contacts the accelerator equipment for heat exchange, carrying away the heat from the accelerator equipment. The heat is then gradually transferred to the atmosphere through heat exchange equipment (plate heat exchangers, refrigeration units, cooling towers, etc.).

[0003] The accelerator cooling water system is divided into an internal water system, an external water system, a water treatment system, and a constant temperature water system. In the external water system, because the cooling tower directly contacts the atmosphere for heat exchange, the water quality is poor, and scale easily forms on the heat exchange equipment (cooling tower, heat exchange unit) and piping system. Scale formation negatively impacts the cooling efficiency and service life of the heat exchange equipment and piping system. Traditional methods for addressing scale formation mostly involve adding water treatment agents or scale inhibitors, but these methods often result in water pollution.

[0029] In the embodiments of this specification, "at least one" means one or more, and "more than one" means two or more. "And / or" describes the relationship between related objects, indicating that there can be three relationships. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone.

[0030] The following is combined with Figures 1 to 5 The structure and operation of the accelerator circulating cooling water system provided by the present invention will be described.

[0031] like Figure 1 As shown, a specific embodiment of the present invention provides an accelerator circulating cooling water system, which includes an accelerator first circuit 110, an accelerator second circuit 120, an internal water circuit 200, an external water circuit 300, and a descaling component 400.

[0032] Both the first loop 110 and the second loop 120 of the accelerator are used to cool the accelerator. The first loop 110 cools the core heat-generating components of the accelerator; water flowing through it may be activated, producing radioactive nuclides. The second loop 120 cools the non-core heat-generating components of the accelerator. Since it does not directly contact the core components, the water inside it generally poses no risk of radioactive contamination. In other words, the radioactivity level of the water in the second loop 120 is lower than that of the water in the first loop 110.

[0033] By dividing the cooling circuit into the first accelerator circuit 110 and the second accelerator circuit 120, water that may contain radioactive nuclides can be confined to the first accelerator circuit 110 and the internal water circuit 200 connected to it, thereby preventing radioactive substances from entering the external water circuit 300 through the scale inhibition circuit 500 and spreading into the environment, thus improving the operational safety of the system.

[0034] The internal water circuit 200 includes an internal water pipeline, and a first water tank 210, a first water pump 220, and a first heat exchange channel of a heat exchanger 600 disposed on the internal water pipeline. The inlet of the first water tank 210 is connected to the outlet of the first circuit 110 of the accelerator and the outlet of the second circuit 120 of the accelerator. The outlet of the first water tank 210 is connected to the inlet of the first circuit 110 of the accelerator and the inlet of the second circuit 120 of the accelerator through the first heat exchange channel. The first water pump 220 is used to provide circulation power for the internal water.

[0035] Under the action of the first water pump 220, the internal water circulates in a closed loop consisting of the first accelerator loop 110, the second accelerator loop 120, the first water tank 210, and the first heat exchange channel. Specifically, the high-temperature internal water flowing out of the first accelerator loop 110 and the second accelerator loop 120 collects and enters the first water tank 210. The first water tank 210 acts as a buffer and pressure stabilizer, and can replenish the internal water loop 200. Subsequently, the water is drawn from the first water tank 210 by the first water pump 220 and pumped to the first heat exchange channel. Here, the high-temperature internal water exchanges heat with the low-temperature external water in the second heat exchange channel through the wall of the heat exchanger 600, and its own temperature decreases, turning into low-temperature internal water. The cooled low-temperature internal water flows out of the first heat exchange channel and is redistributed to the first accelerator loop 110 and the second accelerator loop 120, thus forming a closed loop that continuously cools the accelerator. This closed-loop design can isolate the internal water from the external environment, preventing the leakage of radioactive materials that may exist in the internal water, while transferring heat to the external water circuit 300 through indirect heat exchange.

[0036] The external water circuit 300 includes an external water pipeline, and a cooling tower 310, a third water pump 320, and a second heat exchange channel of a heat exchanger 600 installed on the external water pipeline. The outlet of the cooling tower 310 is connected to the inlet of the second heat exchange channel, and the outlet of the second heat exchange channel is connected to the inlet of the cooling tower 310. The third water pump 320 is used to provide circulation power for the external water.

[0037] Under the action of the third water pump 320, the external water circulates in the pipeline consisting of the cooling tower 310 and the second heat exchange channel, forming an open-loop cooling system. Specifically, the low-temperature external water cooled by the cooling tower 310 is pumped by the third water pump 320 to the second heat exchange channel, where it exchanges heat with the high-temperature internal water in the first heat exchange channel, absorbing heat and increasing its own temperature. The heated external water flows out from the second heat exchange channel and returns to the cooling tower 310, where it releases heat into the atmosphere through evaporation and convection heat exchange with the air, completing the cooling process before entering the next cycle. This external water loop 300 undertakes the final task of dissipating the total heat of the system, releasing the waste heat generated by the accelerator into the environment through the cooling tower 310.

[0038] The inlet of the descaling component 400 is connected to the outlet of the cooling tower 310 and the inlet of the second heat exchange channel, and the outlet of the descaling component 400 is connected to the inlet of the cooling tower 310 and the outlet of the second heat exchange channel, for descaling external water. The descaling component 400 is installed in parallel with the second heat exchange channel on the pipeline, forming a bypass treatment system. The low-temperature external water flowing out of the cooling tower 310 is diverted here; part of the water flows into the second heat exchange channel to participate in the main circulation heat exchange, and the other part of the water enters the descaling component 400. Inside the descaling component 400, scale-forming ions in the water are precipitated and precipitated through physical means, achieving water purification. The treated water flows out of the descaling component 400, merges with the high-temperature external water from the second heat exchange channel, and returns to the cooling tower 310 together.

[0039] This bypass descaling method allows for continuous treatment of circulating water without interrupting the main cooling cycle, gradually reducing the scaling trend of the entire external water circuit 300. This slows down the scaling rate of the cooling tower 310 and heat exchanger 600, maintains the system's heat exchange efficiency, reduces reliance on chemical descaling agents, and lowers operating costs and the risk of water pollution.

[0040] In this embodiment, by setting up independent internal water circuits 200 and external water circuits 300, and utilizing heat exchanger 600 for heat exchange, effective isolation is achieved between the internal cooling water, which may contain radioactive materials, and the external environment, thus improving the operational safety of the system. Simultaneously, by installing a descaling component 400 in parallel in the external water circuit 300, continuous bypass physical descaling of the circulating external water can be performed without affecting the main circulation heat exchange. This slows down the rate of scaling on the cooling tower 310, heat exchanger 600, and pipelines, helping to maintain high heat exchange efficiency of the system in the long term and reducing dependence on chemical descaling agents, thereby lowering operating costs and the risk of water pollution.

[0041] like Figure 1 As shown, in some embodiments of the present invention, the accelerator circulating cooling water system further includes a scale inhibition circuit 500, which includes a second water tank 510, a second one-way flow element 520, and a second water pump 530.

[0042] The inlet of the second water tank 510 is connected to the outlet of the second circuit 120 of the accelerator; the outlet of the second one-way flow element 520 is connected to the inlet of the cooling tower 310; the inlet of the second water pump 530 is connected to the outlet of the second water tank 510, and the outlet of the second water pump 530 is connected to the inlet of the second one-way flow element 520.

[0043] When the second water pump 530 starts operating, a portion of the magnetized, high-temperature internal water discharged from the second accelerator loop 120 flows into the second water tank 510, which provides a buffer and water reserve for the scale inhibition loop 500. Subsequently, water is drawn from the outlet of the second water tank 510 by the second water pump 530 and transported through the second one-way flow element 520, ultimately entering the inlet pipe of the cooling tower 310. The second one-way flow element 520 ensures that water flows unidirectionally from the scale inhibition loop 500 into the cooling tower 310, preventing water from the external water loop 300 from flowing back into the scale inhibition loop 500. The scale inhibition loop 500 is designed to utilize water from the second accelerator loop 120. This water is relatively pure and, after being subjected to an electromagnetic field, its salt-dissolving properties may be altered. By introducing this water into the external water loop 300, scaling can be inhibited, thus achieving the reuse of existing resources within the system.

[0044] When water replenishment is required for cooling tower 310, the water level in cooling tower 310 can be first discharged to the preset replenishment water level line. Then, the second water pump 530 is started, allowing water from the scale inhibition circuit 500 to be replenished to cooling tower 310 via the second one-way flow element 520 until the normal operating water level is reached. Regularly replenishing cooling tower 310 through scale inhibition circuit 500 can replace and renew the water in external water circuit 300, gradually improving the overall water quality of external water circuit 300, diluting the concentration of scale-forming ions in the water, and thus slowing down the scaling rate of the entire external water system (including cooling tower 310 and pipelines).

[0045] During the cleaning process of cooling tower 310, the water inside is first drained, and large debris is removed, followed by pre-cleaning with a high-pressure water gun. Then, by starting the second water pump 530 and opening the relevant valves, water from the second accelerator circuit 120 is injected into the cooling tower 310 via the scale-inhibiting circuit 500 until the water level reaches the preset cleaning level. Because this cleaning water originates from the pure water source of the second accelerator circuit 120 and has undergone a strong electromagnetic field environment, its ability to dissolve salt scale is altered compared to ordinary water. Soaking the cooling tower 310 with this water for, for example, 24 hours can soften and partially dissolve stubborn scale adhering to the inside of the tower. After soaking, the cooling tower 310 is then cleaned routinely. At this point, the scale is more easily removed, thus enhancing the effect of physical cleaning and correspondingly reducing the amount of chemical cleaning agents used. After cleaning, the wastewater is discharged, and water is replenished again through the scale inhibition circuit 500 or other water replenishment system to the normal operating water level of the cooling tower 310.

[0046] In this embodiment, by adding a scale-inhibiting circuit 500, water with specific physicochemical properties in the second circuit 120 of the accelerator is utilized, thereby optimizing the water replacement and cleaning process. Specifically, in the water replenishment condition, the water quality of the external water circuit 300 can be improved, while in the cleaning condition, the surplus water resources within the system are utilized to enhance the cleaning effect. This achieves internal recycling and reuse of system resources, improves resource utilization, and reduces the environmental impact and costs associated with the use of chemical agents.

[0047] Optionally, the second one-way flow element 520 is a one-way valve or a check valve.

[0048] like Figure 1As shown, in some embodiments of the present invention, the scale-inhibiting circuit 500 further includes a third flow control element 540. The third flow control element 540 is disposed between the outlet of the accelerator second circuit 120 and the inlet of the second water tank 510, with its inlet connected to the outlet of the accelerator second circuit 120 and its outlet connected to the inlet of the second water tank 510. The third flow control element 540 is a valve.

[0049] When the third flow control element 540 is opened, the accelerator second circuit 120 and the second water tank 510 are connected, allowing water to flow through. Conversely, when the third flow control element 540 is closed, the water path between them is cut off, thus preventing water from flowing from the accelerator second circuit 120 into the second water tank 510. This on / off function provides selective control over whether the scale-inhibiting circuit 500 is enabled, allowing it to draw water from the internal water circuit 200 when a water replenishment or cleaning task is needed, while remaining isolated during normal system operation, thereby ensuring the pressure and flow stability of the main internal water circulation.

[0050] Furthermore, by adjusting the opening of the valve core inside the third flow control element 540, the size of its flow cross section can be adjusted, thereby controlling the water flow from the second circuit 120 of the accelerator into the second water tank 510. This allows operators to precisely control the water volume according to the actual water replenishment rate or cleaning water injection requirements of the cooling tower 310, achieving refined management of the water replenishment and cleaning process and avoiding the impact on the water level control of the cooling tower 310 caused by excessive instantaneous flow.

[0051] In some embodiments of the invention, the inner water circuit 200 further includes a first one-way flow element 230. The inlet of the first one-way flow element 230 is connected to the outlet of the accelerator second circuit 120, and the outlet of the first one-way flow element 230 is connected to the inlet of the first water tank 210. The first one-way flow element 230 allows water to flow from the accelerator second circuit 120 to the first water tank 210, while preventing water from flowing in the opposite direction.

[0052] The water flow from the first accelerator loop 110 and the water flow from the second accelerator loop 120 converge before entering the first water tank 210. Under certain operating conditions (e.g., pressure fluctuations), there is a risk that water in the first accelerator loop 110, which may contain radioactive nuclides, could flow backwards into the pipeline of the second accelerator loop 120. By setting up a first one-way flow element 230, which allows only one-way flow, this potential reverse flow path can be blocked. This prevents water from the first accelerator loop 110 from entering the second water tank 510 supplying water to the scale inhibition loop 500 via the pipeline of the second accelerator loop 120, thereby preventing potentially radioactive water from being ultimately introduced into the cooling tower 310, which is an open system. This further enhances the safety of the entire cooling system operation and ensures that radioactive materials are reliably contained within the inner water loop 200.

[0053] Optionally, the first one-way flow element 230 is a one-way valve or a check valve.

[0054] In some embodiments of the present invention, the internal water circuit 200 further includes a first flow control element 240 and a second flow control element 250.

[0055] The inlet of the first flow control element 240 is connected to the outlet of the first loop 110 of the accelerator, and the outlet of the first flow control element 240 is connected to the inlet of the first water tank 210 and the outlet of the first one-way flow element 230. When the first flow control element 240 is opened, the high-temperature internal water from the first loop 110 of the accelerator can flow into the first water tank 210. When the first flow control element 240 is closed, the flow path is cut off. By adjusting the opening degree of the first flow control element 240 to control the water flow, the cooling water flow through the core heat-generating components of the accelerator can be distributed and adjusted to match the heat dissipation requirements under different operating conditions, thereby achieving temperature control of the core components.

[0056] The inlet of the second flow control element 250 is connected to the outlet of the second loop 120 of the accelerator, and the outlet of the second flow control element 250 is connected to the inlet of the first unidirectional flow element 230 and the inlet of the third flow control element 540. When the second flow control element 250 is open, the high-temperature internal water of the second loop 120 of the accelerator can flow into the main circulation of the internal water loop 200 or be diverted to the scale inhibition loop 500. When the second flow control element 250 is closed, the flow path is cut off. The setting of the second flow control element 250 allows for independent control of the cooling flow of non-core heat-generating components of the accelerator. In addition, since its outlet is connected to both the main internal water loop and the scale inhibition loop 500, by adjusting the opening of this element, a balance and distribution of flow can be achieved between meeting the cooling needs of the second loop itself and supplying water to the scale inhibition loop 500, thereby improving the flexibility of system operation and the efficiency of water resource utilization.

[0057] Optionally, the first flow control element 240 is a valve.

[0058] Optionally, the second flow control element 250 is a valve.

[0059] like Figures 2 to 5 As shown, in some embodiments of the present invention, the descaling assembly 400 includes a descaling tank (not shown) and a descaling unit. The descaling tank has an internal receiving cavity, and the descaling tank has an inlet and an outlet communicating with the receiving cavity. External water discharged from the cooling tower 310 enters the receiving cavity through the inlet of the descaling tank, passes through the descaling unit, and exits the receiving cavity through the outlet of the descaling tank.

[0060] The descaling unit includes a second descaling module 420, a partition plate 430, and a first descaling module 440.

[0061] The second descaling module 420 is disposed in the receiving cavity; the second descaling module 420 has a second descaling chamber, and a second side opening 423 is provided on the side of the second descaling module 420.

[0062] A partition plate 430 is disposed in the second descaling chamber to divide the second descaling chamber into an upper chamber and a lower chamber. A bottom through hole 431 is provided on the partition plate 430, which connects the upper chamber and the lower chamber. The second side opening 423 is connected to the upper chamber.

[0063] The first descaling module 440 is arranged inside the receiving cavity and is located on the upper side of the second descaling module 420. The first descaling module 440 has a first descaling chamber inside, a top opening 444 is provided on the top of the first descaling module 440, and a first side opening 445 is provided on the side of the first descaling module 440. The position of the first side opening 445 corresponds to the position of the water inlet, so that external water enters the first descaling chamber from the water inlet and the first side opening 445.

[0064] The external water to be treated enters through the inlet of the descaling tank and flows into the first side opening 445 on the side of the first descaling module 440, entering the first descaling chamber. Since the bottom of the first descaling chamber is closed, the water flow gathers here until it is full, and then overflows from the top opening 444, which changes the speed and direction of the water flow, which helps the precipitation of scale-forming ions in the water.

[0065] Overflowing water flows into the receiving cavity of the descaling tank, and then enters the upper chamber of the second descaling module 420 through the second side opening 423. Afterwards, the water flows through the bottom through-hole 431 on the partition plate 430 and enters the lower chamber. This multi-stage, winding flow path prolongs the residence time of water within the descaling unit and increases the contact area between the water and the inner wall of the unit. In the lower chamber, due to its structural design, the water flow velocity is significantly reduced, forming a stagnant zone. In this area, sufficient static settling and adhesion conditions are provided for scale-forming substances in the water, causing scale to preferentially concentrate and accumulate here.

[0066] By incorporating a descaling unit with the aforementioned complex flow channel structure within the descaling tank, a preferred site for scale formation is artificially provided. In this way, most of the scale in the circulating external water will concentrate within the descaling unit, rather than adhering to the critical heat exchange surfaces of the cooling tower 310 or heat exchanger 600. This achieves the physical capture of scale in pre-designed, easily cleanable or replaceable components, thereby protecting the main system equipment and maintaining its long-term heat exchange efficiency.

[0067] Optionally, the descaling unit also includes a connecting column 460. The connecting column 460 is placed inside the receiving cavity and located on the side of the second descaling module 420 and the first descaling module 440. It is used to connect the second descaling module 420 and the first descaling module 440, thereby combining them into a structurally integrated descaling unit. This ensures that the first descaling module 440 and the second descaling module 420 maintain a stable relative position during operation, especially under the impact of water flow, thus maintaining the integrity of the preset flow channel structure inside the descaling unit.

[0068] Specifically, the connecting column 460 is connected to the first descaling module 440 and the second descaling module 420 using fasteners such as bolts, forming a detachable connection. When maintenance is required, operators can disassemble the originally assembled descaling unit into independent components such as the first descaling module 440, the second descaling module 420, and the connecting column 460 by removing these bolts. This makes cleaning of each component of the descaling unit, especially the internal chambers and complex surfaces, feasible and convenient. The scale adhering to these components can be removed more thoroughly, reducing the difficulty of maintenance and facilitating the regeneration and reuse of the descaling unit.

[0069] Optionally, there may be multiple connecting columns 460, which are arranged at intervals along the circumference of the second descaling module 420 to improve the structural stability of the descaling unit.

[0070] Optionally, the descaling unit and the descaling tank can be detachably connected, making it easy to replace and clean the descaling unit.

[0071] Optionally, the top opening 444 has a polygonal cross-section, and scale is more likely to form at the corners of the polygon.

[0072] Optionally, the cross-section of the bottom through hole 431 can be circular or polygonal.

[0073] like Figure 2 , Figure 3 and Figure 5 As shown, in some embodiments of the present invention, the second descaling module 420 includes a bottom tray 421 and a bottom guide plate 422.

[0074] The bottom tray 421 has a cylindrical structure; the partition plate 430 is disposed inside the bottom tray 421 and is spaced apart from the bottom plate of the bottom tray 421 to form a lower chamber. The structural design of the lower chamber provides a relatively slow flow area for water, which facilitates the sedimentation and precipitation of suspended or dissolved scale-forming substances in the water.

[0075] The bottom guide plate 422 is an arc-shaped plate; the bottom guide plate 422 is disposed on the upper side of the partition plate 430; the bottom guide plate 422 and the partition plate 430 enclose the upper chamber. The arc-shaped inner wall of the bottom guide plate 422 provides a guiding surface for the water flowing in from the side, so that the water flows along a preset path in this chamber.

[0076] In the assembled state, the first descaling module 440 is positioned above the bottom guide plate 422, so that the bottom of the first descaling module 440 acts to close the top opening of the bottom guide plate 422. This ensures that water entering from the receiving cavity must enter the upper chamber through the second side opening 423 of the second descaling module 420, rather than directly from the top. This ensures that the water flows through the entire descaling unit according to the designed path, so as to achieve the expected scale capture effect.

[0077] like Figure 2 , Figure 4 and Figure 5 As shown, in some embodiments of the present invention, the first descaling module 440 includes a middle tray 441, a middle baffle plate 442, and a top tray 443.

[0078] The middle tray 441 is disposed on the upper side of the second descaling module 420, forming the base and bottom plate of the first descaling module 440. The middle guide plate 442 is an arc-shaped plate; the middle guide plate 442 is disposed on the upper side of the middle tray 441, and its arc-shaped sidewalls form the lateral boundary of the chamber.

[0079] The top tray 443 is disposed on the upper side of the middle guide plate 442; the bottom of the top tray 443 has a top opening 444; wherein, the middle tray 441, the middle guide plate 442 and the top tray 443 together form a first descaling chamber with a first side opening 445 on the side.

[0080] In this embodiment, the external water flowing in from the inlet of the descaling tank must first enter the first descaling chamber laterally through the first side opening 445. Due to the blockage at the bottom of the middle tray 441, the water flow cannot descend and can only accumulate in the first descaling chamber until it is full, and finally overflow from the top opening 444 at the bottom of the top tray 443. This flow process, from entering laterally, stagnating in the chamber, and then overflowing upwards through the opening, causes a change in the water flow velocity and direction, providing physical conditions for the precipitation of scale-forming ions in the water, and promoting the formation and adhesion of scale in this first descaling chamber.

[0081] Optionally, the top tray 443 is provided with a hanging lug on its upper side for easy engagement with a hook to facilitate the removal of the descaling unit from the descaling tank.

[0082] like Figure 2 , Figure 3 and Figure 5 As shown, in some embodiments of the present invention, the descaling unit further includes a blocking module 450. The blocking module 450 is disposed in the upper chamber and forms a retention area with the inner sidewall of the upper chamber. The retention area communicates with the lower chamber through the bottom through hole 431.

[0083] After the water enters the upper chamber, its direct path to the bottom through-hole 431 is blocked by the presence of the blocking module 450, forcing it to first flow around through the stagnation zone. In this way, an area with significantly reduced water flow velocity is artificially created, prolonging the water's residence time in this area, thus creating more favorable conditions for the precipitation and adhesion of scale-forming substances in the water.

[0084] After being treated at low speed in the retention zone, the water continues to flow into the lower chamber where the flow rate is even slower. By adding a blocking module 450 and forming a retention zone, a pretreatment stage is added before entering the final settling zone (lower chamber), which can further promote the formation of scale, thereby improving the overall scale capture rate of the descaling unit.

[0085] like Figure 5As shown, optionally, the blocking module 450 includes a first guide plate 451 and multiple second guide plates 452. The first guide plate 451 is disposed in the upper chamber and spans across the bottom through hole 431, directly blocking the path of water flowing vertically downward through the bottom through hole 431, forcing the water to flow around in the upper chamber to ensure that the water flows through the set retention area. The first guide plate 451 has multiple first slots 453, which are spaced apart along the length of the first guide plate 451. The second guide plates 452 are engaged with the first slots 453, and the multiple second guide plates 452 correspond one-to-one with the multiple first slots 453, realizing the positioning and connection between the two components. The slot-engaging connection method allows the assembly and disassembly of the blocking module 450 to be done without complicated tools, providing convenience for subsequent cleaning or replacement of scale adhering to each plate.

[0086] After assembly, the second guide plate 452, the first guide plate 451, and the inner wall of the upper chamber together form a stagnant zone, essentially creating a labyrinthine or grid-like flow channel composed of multiple baffles within the upper chamber. When water is forced through this complex channel, its flow path is lengthened, and multiple local eddies and low-velocity regions are formed during the flow around the plates. These conditions provide more opportunities and time for the precipitation and adhesion of scale-forming ions in the water. Simultaneously, the plates themselves provide a larger surface area for scale adhesion, thereby improving the efficiency of scale capture per unit volume.

[0087] Optionally, a second slot is provided on the second guide plate 452, and the first guide plate 451 is inserted into the second slot.

[0088] Optionally, both the first guide plate 451 and the second guide plate 452 are rectangular plates, which make it easier for scale to form at the corners.

[0089] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
