Double-circulation water radiator for energy-saving large generator set

Abstract

This invention discloses a dual-circulation water radiator for energy-saving large generator sets, relating to the field of power generation equipment technology. It includes a generator body and a radiator body located at its end. The radiator body comprises a first circulation radiator, a second circulation radiator, and an adjustment assembly. This invention, through the adjustment assembly, adjustment components, and air supply equipment, incorporates baffles with angled nozzles within the air cavity. When a temperature sensor detects that the high-temperature circulating coolant or the inlet air temperature inside the air cavity exceeds a corresponding temperature threshold, the control system activates the air supply equipment to divert ambient air through a main pipe into the flow channels within multiple baffles, ultimately ejecting it through multiple angled nozzles. This allows the injected ambient air to mix with the main airflow heated by the first circulation radiator within the air cavity, reducing the gas temperature on the windward side of the second circulation radiator and increasing the heat transfer temperature difference.

Description

Technical Field

[0001] This invention relates to the field of power generation equipment technology, and in particular to a dual-circulation water radiator for energy-saving large generator sets. Background Technology

[0002] In the field of power generation equipment, high-power diesel or gas generator sets generally adopt a dual-cycle system with a high-temperature cycle core and a low-temperature cycle core. The high-temperature cycle is used to cool the engine cylinder liner and cylinder head, while the low-temperature cycle is used to cool the intercooler and lubricating oil cooler. In order to save equipment installation space and reduce manufacturing costs, existing technology usually sets the two cores in series in the same frame to form an integrated dual-core radiator.

[0003] However, since the low-temperature circulating core is located on the windward side, the ambient gas must first flow through the low-temperature circulating core to absorb heat before entering the high-temperature circulating core. This results in a large heat dissipation from the low-temperature core under extreme conditions such as high temperatures in summer or full-load operation of the unit, and a significant increase in the temperature on the outlet side. When this heated gas enters the high-temperature core, it will cause the inlet air temperature of the high-temperature core to be too high, resulting in insufficient effective heat transfer temperature difference. This limits the heat dissipation capacity of the high-temperature circulation and can easily cause engine water temperature alarms or load reduction.

[0004] Secondly, during seasons with abundant fibrous floating matter such as willow catkins and poplar fluff, although some of the fluff is intercepted on the windward side of the low-temperature circulating core, the airflow speed at the gap between the two cores decreases and turbulence is generated as the ambient gas passes through them sequentially. This results in the fluff clogging on the windward side of the high-temperature circulating core being more pronounced than on the windward side of the low-temperature circulating core, significantly reducing the effective ventilation area of ​​the high-temperature circulating core. Moreover, even if some blockage remains on the windward side of the low-temperature circulating core, it can be cleaned directly with water guns or air guns. However, these conventional devices can only clean the low-temperature core and cannot reach the deposits on the windward side of the high-temperature core. Consequently, existing technology not only struggles to detect the blockage on the windward side of the high-temperature core in a timely manner, but also requires the dismantling of both cores during cleaning, which is extremely time-consuming and labor-intensive.

[0005] To address these issues, this invention proposes a dual-circulation water radiator for energy-saving large generator sets. Summary of the Invention

[0007] To achieve the above objectives, the present invention provides the following technical solution: a dual-circulation water radiator for an energy-saving large generator set, comprising a generator body and a radiator body located at its end, wherein the radiator body comprises: A first circulating radiator is located on one side close to the generator body, and a second circulating radiator is located on the other side of the first circulating radiator. An adjustment component is disposed between the first circulating radiator and the second circulating radiator. The adjustment component includes a frame, and an air cavity is formed inside the frame. An adjustment element is disposed inside the air cavity, and the adjustment element can introduce ambient air into the air cavity.

[0008] Preferably, the regulating component includes multiple partitions located within the air cavity, a protective cover is provided on the top of the frame, an equipment cavity is formed inside the protective cover, connecting pipes that penetrate into the equipment cavity are fixedly connected inside each of the multiple partitions, and multiple flow channels communicating with the connecting pipes are opened inside each of the multiple partitions. Multiple spray holes communicating with the flow channels are opened on both sides of the partitions, and a common main pipe is provided at one end of each of the multiple connecting pipes located inside the equipment cavity. An air supply device is connected to the outside of the main pipe to introduce ambient air into the main pipe and multiple connecting pipes in sequence, and spray it out through the multiple spray holes.

[0009] Preferably, a fan is provided on the side of the first circulating radiator near the generator body, and the axis of the nozzle forms an angle with the axis of the fan so that the outlet end of the nozzle faces the side of the second circulating radiator.

[0010] Preferably, the plurality of connecting pipes are located at one end of the partition plate near the generator body and are rotatably connected to the frame. The main pipe is rotatably connected to the plurality of connecting pipes in a sealed manner. The interior of the equipment cavity is provided with a drive assembly that forms a drive engagement with the plurality of connecting pipes. The drive assembly can drive the partition plate to deflect along the axis of the connecting pipes.

[0011] Preferably, the driving assembly includes two cooperating first moving plates and second moving plates. A driving member is provided on one side of the first moving plate and the second moving plate. The driving member enables the first moving plate and the second moving plate to move in opposite directions. The first moving plate and the second moving plate are respectively provided with a plurality of staggered first connecting members and second connecting members so that the rotation directions of two adjacent connecting pipes are opposite.

[0012] Preferably, the first connector includes a first positioning pin fixedly connected to a first connecting plate, a portion of the connecting tube is fixedly connected to the circumferential side of the first connecting plate, the first connecting plate has a first sliding groove inside, and the first positioning pin is slidably connected to the first sliding groove.

[0013] Preferably, the second connector includes a second positioning pin fixedly connected to the second connecting plate, a second connecting plate is fixedly connected to the circumferential side of a portion of the connecting tube, a second sliding groove is provided inside the second connecting plate, and the second positioning pin is slidably connected to the second sliding groove.

[0014] Preferably, the driving component includes a piston cylinder fixedly connected inside the equipment cavity, with piston rods slidably and sealed at both ends inside the piston cylinder, mounting plates fixedly connected to one side of the first moving plate and the second moving plate, and the two piston rods extending out of the piston cylinder being fixedly connected to the corresponding mounting plates, and an oil supply device connected to the outside of the piston cylinder.

[0015] Preferably, one end of the main pipe is provided with a connecting pipe, the end of the connecting pipe is provided with a three-way valve, the gas supply device is connected to the input end of the three-way valve through a pipe, and the other end of the three-way valve is connected to a liquid supply device through a pipe.

[0016] Preferably, the partition is provided with a plurality of equally spaced guide strips on both sides.

[0017] The beneficial effects of this invention are: This invention, through the setting of adjustment components, adjustment parts, and air supply equipment, sets up baffles with oblique nozzles in the air cavity. When the temperature sensor detects that the temperature of the high-temperature circulating coolant or the inlet air temperature inside the air cavity exceeds the corresponding temperature threshold, the control system starts the air supply equipment to divert the ambient air through the main pipe to the flow channels inside multiple baffles, and finally spray it out through multiple oblique nozzles. This allows the injected ambient air to mix with the main airflow heated by the first circulating radiator in the air cavity, reducing the gas temperature on the windward side of the second circulating radiator and increasing the heat transfer temperature difference.

[0018] Meanwhile, by directly introducing ambient air into the air cavity and monitoring with multiple temperature sensors, the temperature of the second-cycle radiator can be controlled without significantly increasing the fan speed on one side of the first-cycle radiator. In fact, significantly increasing the fan speed would have a negative effect on the temperature of the first-cycle radiator, causing it to deviate from its optimal temperature range. By introducing a small amount of ambient air into the air cavity for mixed heat exchange, a better cooling effect is achieved with lower energy consumption, significantly reducing the overall energy consumption of the system.

[0029] 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. Example 1

[0030] In existing technologies, because the low-temperature circulating core is located on the windward side, the ambient gas must first flow through the low-temperature circulating core to absorb heat before entering the high-temperature circulating core. This results in a large heat dissipation from the low-temperature core under extreme conditions such as high temperatures in summer or full-load operation of the unit, and a significant increase in the temperature on the outlet side. When this heated gas enters the high-temperature core, it causes the inlet air temperature of the high-temperature core to be too high, resulting in insufficient effective heat transfer temperature difference. This limits the heat dissipation capacity of the high-temperature circulation and can easily trigger engine coolant temperature alarms or load reduction.

[0031] This embodiment was invented to solve the above problems.

[0032] Please see Figures 1 to 9 As shown, an embodiment of the present invention provides a dual-circulation water radiator for an energy-saving large generator set, comprising a generator body 1 and a radiator body 2 located at its end. The radiator body 2 includes a first circulation radiator 21, a second circulation radiator 22, and an adjustment component 3.

[0033] The first circulating radiator 21 is located on one side close to the generator body 1, and the second circulating radiator 22 is located on the other side of the first circulating radiator 21. The temperature of the cooling medium inside the first circulating radiator 21 is lower than the temperature of the cooling medium inside the second circulating radiator 22. The adjusting component 3 is located between the first circulating radiator 21 and the second circulating radiator 22. The adjusting component 3 includes a frame 31, which has a rectangular structure and is fixedly connected to the first circulating radiator 21 and the second circulating radiator 22 respectively. The frame 31 is enclosed to form a wind cavity 32. An adjusting component is provided in the wind cavity 32, which can introduce ambient air into the wind cavity 32.

[0034] Please see Figures 3 to 7 As shown, the adjustment component 3 includes multiple partitions 33 located within the air cavity 32. A protective cover 34 is provided on the top of the frame 31, and an equipment cavity is formed inside the protective cover 34. Each of the multiple partitions 33 has a connecting pipe 35 that extends into the equipment cavity. Each of the multiple partitions 33 has multiple flow channels 36 that communicate with the connecting pipes 35. Multiple nozzles 37 that communicate with the flow channels 36 are respectively provided on both sides of the partitions 33. One end of each of the multiple connecting pipes 35 located in the equipment cavity is provided with the same main pipe 38. An air supply device is connected to the main pipe 38 to introduce ambient air into the main pipe 38 and the multiple connecting pipes 35 in sequence, and spray it out through the multiple nozzles 37. In this embodiment, the air supply device is a centrifugal fan or a blower. When the air supply device is started, it can introduce ambient air into the main pipe 38 and distribute it to the flow channels 36 of the multiple partitions 33.

[0035] A fan is provided on the side of the first circulating radiator 21 near the generator body 1. When the fan rotates, it allows the ambient air to pass through the first circulating radiator 21 and the second circulating radiator 22 in sequence to cool the liquid medium circulating inside the two radiators. The axis of the nozzle 37 forms an angle with the axis of the fan so that the outlet end of the nozzle 37 faces the windward side of the second circulating radiator 22.

[0036] Furthermore, the two sides of the partition 33 are provided with a plurality of equally spaced guide strips 39. The cross-section of the guide strips 39 is an arc-shaped structure, which is used to guide the airflow and reduce the eddies generated in the air cavity 32. In addition, when the main airflow after heat exchange through the first circulating radiator 21 passes through the guide strips 39, it can reduce the turbulence of the main airflow, make the airflow more orderly, and thus reduce the resistance and noise in the air cavity 32.

[0037] In use, the worker fixes the adjustment component 3 between the first circulating radiator 21 and the second circulating radiator 22, so that the frame 31 and the two circulating radiators form a sealed connection, and a wind cavity 32 is formed inside the frame 31. After the generator body 1 is started, when the fan on the side of the first circulating radiator 21 close to the generator body 1 starts to work, the ambient air passes through the first circulating radiator 21 under the suction of the fan and enters the cavity, and then enters the second circulating radiator 22 through the cavity for heat exchange.

[0038] When the generator set is detected to be in extreme conditions such as high summer temperatures or full load operation, the air supply equipment is started by the control system set on the generator body 1, so that the ambient air is introduced into the main pipe 38 and distributed to each connecting pipe 35, and then sprayed out through multiple flow channels 36 and nozzles 37 inside the baffle 33.

[0039] The ambient air ejected from the oblique nozzle 37 mixes with the main airflow heated by the first circulating radiator 21 in the air cavity 32, thereby reducing the temperature of the airflow entering the second circulating radiator 22 and increasing the heat transfer temperature difference.

[0040] In addition, temperature sensors are installed on the coolant outlet pipe of the first circulating radiator 21, the coolant outlet pipe of the second circulating radiator 22, and the side of the air cavity 32 near the second circulating radiator 22. The above three temperature sensors are respectively connected to the control system. When the coolant temperature of the second circulating radiator 22 exceeds the first temperature threshold (e.g., 85°C) or the internal temperature of the air cavity 32 exceeds the second temperature threshold (e.g., 50°C), the control system starts the air supply equipment to allow ambient air to enter the air cavity 32 and mix with the main airflow to reduce the temperature of the second circulating radiator 22.

[0041] Meanwhile, the control system adjusts the power of the air supply equipment or the opening of the air intake valve in real time based on the difference between the actual temperature of the coolant in the second circulating radiator 22 and the target value (such as 80℃) through PID algorithm or piecewise linear control. The greater the temperature difference, the higher the power or the greater the opening of the air intake valve.

[0042] When the temperature of the coolant in the second circulating radiator 22 and the temperature inside the air chamber 32 are lower than the corresponding first temperature threshold and second temperature threshold, respectively, and this continues for a certain period of time, the control system shuts off the air supply equipment.

[0043] In summary, by adjusting the components 3, adjusting parts, and air supply equipment, the present invention sets up a baffle 33 with oblique nozzles 37 in the air cavity 32. When the temperature sensor detects that the temperature of the high-temperature circulating coolant or the inlet air temperature inside the air cavity 32 exceeds the corresponding temperature threshold, the control system starts the air supply equipment to divert the ambient air through the main pipe 38 to the flow channels 36 inside the multiple baffles 33, and finally spray it out through the multiple oblique nozzles 37. This allows the injected ambient air to mix with the main airflow heated by the first circulating radiator 21 in the air cavity 32, reducing the gas temperature on the windward side of the second circulating radiator 22 and increasing the heat transfer temperature difference.

[0044] Meanwhile, by directly introducing ambient air into the air cavity 32 in conjunction with the monitoring of multiple temperature sensors, the temperature control of the second circulating heat sink 22 can be achieved without significantly increasing the fan speed on one side of the first circulating heat sink 21. In fact, significantly increasing the fan speed would have a negative effect on the temperature of the first circulating heat sink 21, causing it to deviate from the optimal temperature range. By introducing a small amount of ambient air into the air cavity 32 for mixed heat exchange, a better cooling effect is achieved with lower energy consumption, significantly reducing the overall energy consumption of the system. Example 2

[0045] In practical use, it was found that during seasons with abundant fibrous floating matter such as willow catkins and poplar fluff, although some of the fluff is intercepted on the windward side of the low-temperature circulating core, the airflow speed at the gap between the two cores decreases and turbulence is generated as the ambient gas passes through them sequentially. This results in more significant blockage of the high-temperature circulating core on the windward side than on the low-temperature core, greatly reducing the effective ventilation area of ​​the high-temperature circulating core. Moreover, even if some blockage remains on the windward side of the low-temperature circulating core, it can be cleaned directly with water guns or air guns. However, these conventional devices can only clean the low-temperature core and cannot reach the deposits on the windward side of the high-temperature core. As a result, existing technology not only makes it difficult to detect the blockage on the windward side of the high-temperature core in a timely manner, but also requires the removal of both cores for cleaning, which is very time-consuming and labor-intensive.

[0046] Therefore, this embodiment is a further improvement on the above embodiment.

[0047] Please see Figures 4 to 9 As shown, multiple connecting pipes 35 are located at one end of the partition 33 near the generator body 1 and are rotatably connected to the frame 31. The main pipe 38 is rotatably connected to the multiple connecting pipes 35 in a sealed manner. The interior of the equipment cavity is provided with a drive assembly 4 that forms a drive cooperation with the multiple connecting pipes 35. The drive assembly 4 can drive the partition 33 to deflect along the axis of the connecting pipes 35.

[0048] The drive assembly 4 includes two cooperating first moving plates 41 and second moving plates 42. A drive member 43 is provided on one side of the first moving plates 41 and second moving plates 42. The drive member 43 enables the first moving plates 41 and second moving plates 42 to move in opposite directions. The first moving plates 41 and second moving plates 42 are respectively provided with a plurality of staggered first connecting members 44 and second connecting members 45 so that the rotation directions of two adjacent connecting pipes 35 are opposite.

[0049] The first connector 44 includes a first positioning pin 441 fixedly connected to the first connecting plate 442. The first connecting plate 442 is fixedly connected to the circumferential side of a portion of the connecting tube 35. A first sliding groove 443 is provided inside the first connecting plate 442. The first positioning pin 441 is slidably connected to the first sliding groove 443.

[0050] The second connector 45 includes a second positioning pin 451 fixedly connected to the second connecting plate 452. The second connecting plate 452 is fixedly connected to the circumferential side of a portion of the connecting tube 35. A second sliding groove 453 is provided inside the second connecting plate 452. The second positioning pin 451 is slidably connected to the second sliding groove 453.

[0051] The driving component 43 includes a piston cylinder 431 fixedly connected inside the equipment cavity. Piston rods 432 are respectively sealed and slidably connected to both ends of the piston cylinder 431. Mounting plates 46 are respectively fixedly connected to one side of the first moving plate 41 and the second moving plate 42. The two piston rods 432 are respectively fixedly connected to the corresponding mounting plates 46 on the side extending out of the piston cylinder 431. An oil supply device is connected to the piston cylinder 431. In this embodiment, the oil supply device includes an oil storage cylinder connected to the piston cylinder 431 through a pipeline. Both the oil storage cylinder and the piston cylinder 431 are filled with hydraulic oil. A piston is sealed and slidably connected inside the oil storage cylinder. A hydraulic rod or electric push rod is provided at the end of the piston away from the piston cylinder 431. The electric push rod can control the movement of the piston and change the internal volume of the piston cylinder 431 through the hydraulic oil, thereby realizing the control of the two moving plates.

[0052] One end of the main pipe 38 is provided with a connecting pipe, and the end of the connecting pipe is provided with a three-way valve 5. The gas supply device is connected to the input end of the three-way valve 5 through a pipe, and the other end of the three-way valve 5 is connected to a liquid supply device through a pipe.

[0053] It should be noted that a differential pressure sensor is installed inside the air cavity 32 on the side near the second circulating radiator 22.

[0054] When in use, if the differential pressure sensor detects that the pressure inside the air cavity 32 or the differential pressure on both sides of the windward side of the second circulating radiator 22 continues to rise and exceeds the preset differential pressure threshold, it is considered that there is significant fibrous blockage on the windward side of the second circulating radiator 22. The control system first increases the air supply power of the air supply equipment and starts the drive component 43, so that the oil supply equipment supplies oil to the piston cylinder 431, pushing the two piston rods 432 inside to move in opposite directions, thereby driving the corresponding first moving plate 41 and second moving plate 42 to move.

[0055] Furthermore, since the first moving plate 41 and the second moving plate 42 are respectively provided with staggered first positioning pins 441 and second positioning pins 451, and these positioning pins are respectively inserted into the corresponding first sliding grooves 443 and second sliding grooves 453, when the first moving plate 41 and the second moving plate 42 generate relative displacement, through the cooperation of the corresponding sliding grooves, positioning pins and connecting plates, the linear motion is converted into torque to drive each connecting pipe 35 to deflect around its own axis. Since the first connecting member 44 and the second connecting member 45 are staggered, the rotation directions of adjacent connecting pipes 35 are opposite, thereby causing the partition 33 fixed inside to also deflect synchronously and alternately.

[0056] refer to Figure 9 As shown, when the baffle 33 reciprocates, a contraction section in a contracted state and a diffusion section in an open state are formed inside the air cavity 32, and the positions of the contraction section and the diffusion section are alternating. When the main airflow passes through the contraction section, it can produce an acceleration effect. Combined with the airflow ejected from the oblique nozzle 37, a strong airflow is formed that can impact the surface of the second circulation radiator 22 to clean the deposits formed on the surface.

[0057] Meanwhile, the control system can be set to a timed cleaning function, so that the drive component 43 can be activated at certain time intervals to change the deflection angle of the partition 33 and clean the second circulation radiator 22 before it becomes significantly blocked.

[0058] In addition, considering that the gas cleaning method is not effective enough for severe blockages, the control system can switch the electric three-way valve 5 to disconnect from the gas supply equipment and connect to the liquid supply equipment. The liquid supply equipment pumps the cleaning fluid into the main pipe 38 through the connecting pipe 35, the three-way valve 5, and the connecting pipe, and then distributes it to each connecting pipe 35. Finally, it is sprayed out from the nozzle 37. The alternating reverse rotating baffle 33 enables the cleaning fluid to perform cross-scan cleaning on the surface of the second circulation radiator 22. In addition, the acceleration effect of the main airflow generated by the rotation of the baffle 33 helps to blow away the loosened blockages.

[0059] It should be noted that the bottom of the air cavity 32 has a funnel-shaped structure and a drain outlet is provided at the lowest point. The drain outlet is connected to a collection device through a pipe. The collection device includes a collection tank for collecting sewage. A water pump can be installed between the collection tank and the drain outlet.

[0060] After the cleaning process has lasted for a certain period of time, the control system can switch the three-way valve 5 again to connect the air supply equipment and use high-speed airflow to blow away and dry the residual cleaning fluid and impurities, ensuring that the radiator quickly returns to working condition.

[0061] In summary, this invention, through the configuration of drive component 4, drive element 43, and liquid supply equipment, enables timed purging and cleaning of the second circulating radiator 22, reducing the frequency of large-area blockages. Furthermore, when the differential pressure sensor detects significant blockage on the windward side of the second circulating radiator 22, the control system switches between gas and liquid to clean and dry its surface. The entire cleaning process does not require disassembly of the two circulating radiators, greatly saving maintenance time and labor costs. It also enables monitoring of whether the windward side of the second circulating radiator 22 is blocked. When workers find that the coolant temperature of the second circulating radiator 22 remains persistently high, they can identify the cause of the fault by checking the blockage signal in the control system.

[0062] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
