Description

Technical Field

[0001] This invention relates to the field of gas generator technology, and in particular to a gas generator set exhaust heat recovery device. Background Technology

[0002] Gas generators are a new type of high-efficiency new energy generator that uses liquefied gas, natural gas and other combustible gases as fuel to replace gasoline and diesel as engine power. They are widely used because they have advantages such as a wide output power range, high reliability in starting and operation, good power generation quality, light weight, small size, simple maintenance and low frequency noise.

[0003] During the operation of a gas generator, a large amount of high-temperature exhaust gas is generated, and the exhaust gas contains a lot of solid impurities. If this exhaust gas is directly discharged, it will not only cause a large waste of waste heat, but also pollute the air, which is not conducive to energy conservation and emission reduction.

[0004] Therefore, most manufacturers currently use different waste gas heat recovery devices. However, some of these devices do not achieve ideal results. The temperature of the treated waste gas remains high, resulting in heat waste during discharge. Furthermore, the solid impurities in the waste gas are not adequately adsorbed and purified, leading to the waste gas failing to meet environmental protection requirements. Additionally, after prolonged operation, solid impurities adhere to the pipes of the current waste gas heat recovery devices, making them difficult to clean and further reducing the effectiveness of waste gas heat recovery. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides a waste gas heat recovery device for gas generator sets, which not only recovers heat from waste gas more fully, but also adsorbs and purifies solid impurities in the waste gas more effectively, and cleans the solid impurities, thereby improving the efficiency of waste gas heat recovery.

[0006] The technical implementation of the present invention is as follows: a gas generator set exhaust heat recovery device includes a main mounting frame, a circular elongated frame, a connecting pipe, a heat conduction component, an absorption component, a water outlet control component, and a dirt removal component. The circular elongated frame is fixedly connected to the main mounting frame, the connecting pipe is fixedly connected to the main mounting frame, the heat conduction component is disposed on the circular elongated frame, the absorption component is disposed on the main mounting frame, the water outlet control component is disposed on the heat conduction component, and the dirt removal component is disposed on the heat conduction component.

[0007] Furthermore, it is particularly preferred that the heat-conducting component includes a long heat-conducting pipe, a heat-conducting ring, and heat-conducting strips. The long heat-conducting pipe is fixedly connected inside a circular long frame. The heat-conducting ring is rotatably connected between the long heat-conducting pipe and the connecting pipe, and the long heat-conducting pipe is connected to the connecting pipe through the heat-conducting ring. Several heat-conducting strips are fixedly connected to the inner wall of the long heat-conducting pipe.

[0008] Furthermore, particularly preferably, the absorption assembly includes a connecting long pipe, a connecting frame, a water inlet pipe, a circular short frame, an arc-shaped pipe, and a water outlet pipe. The connecting long pipe is fixedly connected to the main mounting frame, one end of the connecting long pipe is connected to the circular long frame, the connecting frame is fixedly connected to the other end of the connecting long pipe, the water inlet pipe is fixedly connected to the connecting frame, and the connecting long pipe is connected to the water inlet pipe through the connecting frame. The circular short frame is rotatably connected to the heat-conducting ring, the upper end of the arc-shaped pipe is fixedly connected to the circular long frame and is connected to the circular long frame, the other end of the arc-shaped pipe is connected to the circular short frame, and the water outlet pipe is connected to the top of the circular short frame and is connected to the circular short frame.

[0009] Furthermore, it is particularly preferred that the water outlet control assembly includes a hollow circular frame, a swing arm, a torsion spring, a limiting rod, a baffle plate, and a slotted transmission frame. The hollow circular frame is fixedly connected to the bottom of the long heat-conducting pipe, the swing arm is rotatably connected to the hollow circular frame, the upper part of the swing arm is located inside the long heat-conducting pipe, a torsion spring is connected between the hollow circular frame and the swing arm, the limiting rod is fixedly connected to the swing arm, the baffle plate is slidably connected to the connecting frame, the slotted transmission frame is fixedly connected to the baffle plate, a short slot is formed on the slotted transmission frame, and the limiting rod is slidably connected to the short slot of the slotted transmission frame.

[0010] Furthermore, it is particularly preferred that the impurity removal component includes an L-shaped tube, a spray head, a water outlet inclined frame, a discharge pipe, a blockage block, and a buoyancy ball. One end of the L-shaped tube is connected to and communicates with the connecting long pipe, and the L-shaped tube passes through the connecting pipe. The spray head is fixedly connected to the other end of the L-shaped tube and communicates with the L-shaped tube. The water outlet inclined frame is fixedly connected to the bottom of the long heat-conducting pipe and communicates with the long heat-conducting pipe. The discharge pipe is connected to the lower part of the water outlet inclined frame and communicates with the water outlet inclined frame. The blockage block is slidably connected to the water outlet inclined frame, and the buoyancy ball is fixedly connected to the blockage block.

[0011] Furthermore, it is particularly preferred that an auxiliary adsorption component is also included. The auxiliary adsorption component is disposed on the heat-conducting ring and includes baffles, a drive motor, a spur gear ring, and a spur gear. Several baffles are fixedly connected to the inner wall of the heat-conducting ring. The drive motor is fixedly connected to the bottom of the connecting pipe. The spur gear ring is fixedly connected to the outer wall of the heat-conducting ring. The spur gear is fixedly connected to the output shaft of the drive motor. The spur gear ring is located above the spur gear, and the spur gear meshes with the spur gear ring.

[0012] In addition, it is particularly preferred that a fixing brush is included, which is fixedly connected to the inner wall of the connecting pipe.

[0013] The beneficial effects of this invention are:

[0014] 1. The staff introduces clean water into the inlet pipe and the exhaust gas generated by the gas generator set into the connecting pipe. The heat-conducting strip and long heat-conducting pipe will transfer the heat of the exhaust gas to the clean water in the long circular frame, fully heating the water in the long circular frame. The clean water in the long circular frame will flow into the short circular frame, where the heat-conducting ring will transfer the heat of the exhaust gas to the clean water in the short circular frame, further heating the water in the short circular frame. This process of heating the water using the exhaust gas generated by the gas generator set recovers heat from the exhaust gas.

[0015] 2. The exhaust gas inside the long heat pipe will simultaneously impact the swinging bracket, causing it to swing downwards. This, in turn, will drive the slotted transmission frame to move upwards. The upward movement of the baffle plate will increase the amount of clean water flowing into the connecting pipe. When the amount of exhaust gas flowing into the pipe is large, the long heat pipe and heat-conducting ring can conduct more heat. At the same time, the swinging bracket will swing downwards more, resulting in a greater amount of clean water flowing into the connecting pipe. Thus, the amount of clean water flowing into the connecting pipe can be adjusted by the amount of exhaust gas flowing into the pipe. This allows the heat from the exhaust gas to fully heat the clean water while also reducing the waste of exhaust gas heat and enabling more complete recovery of the heat from the exhaust gas.

[0016] 3. Some of the clean water in the connecting pipe will flow into the spray head, and then the spray head will spray the clean water out. The clean water sprayed out by the spray head will come into contact with the exhaust gas and wash down the solid impurities in the exhaust gas, thereby removing dust and purifying the exhaust gas, and reducing the pollution to the outside world after the exhaust gas is discharged.

[0017] 4. The drive motor drives the spur gear to rotate, which in turn drives the heat-conducting ring and several baffles to rotate together. The rotation of the baffles will make full contact with the solid impurities in the exhaust gas and adsorb the solid impurities in the exhaust gas onto the baffles, thereby further purifying the exhaust gas and further reducing the pollution of the exhaust gas to the outside world.

[0018] 5. As the baffles rotate, they continuously come into contact with the fixed brush. The fixed brush removes the solid impurities adsorbed on the baffles, allowing the baffles to continuously adsorb solid impurities in the exhaust gas, thus improving the purification efficiency of the exhaust gas. At the same time, as the heat-conducting ring rotates, the fixed brush also removes the solid impurities adsorbed on the heat-conducting ring, allowing the heat-conducting ring to continuously absorb heat from the exhaust gas, thereby improving the heat recovery effect of the exhaust gas.

The specific connection methods of each part adopt conventional methods such as bolts, rivets, welding, and bonding that are mature in the prior art, and will not be described in detail here.

[0029] Example 1

[0030] A gas generator set exhaust heat recovery device, such as Figures 1-8As shown, the system includes a main mounting frame 1, a circular elongated frame 2, a connecting pipe 3, a heat-conducting component, an absorption component, a water outlet control component, and a purification component. The circular elongated frame 2 is bolted to the main mounting frame 1, and the connecting pipe 3 is bolted to the main mounting frame 1. The heat-conducting component is located on the circular elongated frame 2 and is used to conduct heat from the waste gas to the clean water to heat it. The absorption component is located on the main mounting frame 1, and the water outlet control component is located on the heat-conducting component. The water outlet control component is used to adjust the flow rate of clean water. The purification component is located on the heat-conducting component and is used to remove solid impurities from the purified waste gas.

[0031] The heat-conducting assembly includes a long heat-conducting pipe 41, a heat-conducting ring 42, and heat-conducting strips 43. The long heat-conducting pipe 41 is bolted to the circular long frame 2. The heat-conducting ring 42 is rotatably connected between the long heat-conducting pipe 41 and the connecting pipe 3, and the long heat-conducting pipe 41 is connected to the connecting pipe 3 through the heat-conducting ring 42. Several heat-conducting strips 43 are welded on the inner wall of the long heat-conducting pipe 41.

[0032] The absorption assembly includes a connecting long pipe 51, a connecting frame 52, a water inlet pipe 53, a circular short frame 54, an arc-shaped pipe 55, and a water outlet pipe 56. The connecting long pipe 51 is fixedly connected to the mounting main frame 1, and one end of the connecting long pipe 51 is connected to the circular long frame 2. The connecting frame 52 is fixedly connected to the other end of the connecting long pipe 51. The water inlet pipe 53 is fixedly connected to the connecting frame 52, and the connecting long pipe 51 is connected to the water inlet pipe 53 through the connecting frame 52. The circular short frame 54 is rotatably connected to the heat-conducting ring 42. The upper end of the arc-shaped pipe 55 is fixedly connected to the circular long frame 2, and the arc-shaped pipe 55 is connected to the circular long frame 2. The other end of the arc-shaped pipe 55 is connected to the circular short frame 54. The water outlet pipe 56 is connected to the top of the circular short frame 54 and is connected to the circular short frame 54.

[0033] The water outlet control assembly includes a hollow circular frame 61, a swing lever 62, a torsion spring 63, a limiting rod 64, a baffle plate 65, and a slotted transmission frame 66. The hollow circular frame 61 is hinged to the bottom of the long heat-conducting pipe 41. The swing lever 62 is rotatably connected to the hollow circular frame 61, with its upper part located inside the long heat-conducting pipe 41. A torsion spring 63 is connected between the hollow circular frame 61 and the swing lever 62 via a hook. The torsion spring 63 is sleeved on the swing lever 62. The limiting rod 64 is hinged to the swing lever 62 and is horizontally positioned. The baffle plate 65 is slidably connected to the connecting frame 52. The slotted transmission frame 66 is bolted to the baffle plate 65 and has a short slot. The limiting rod 64 is slidably connected to the short slot of the slotted transmission frame 66.

[0034] The impurity removal assembly includes an L-shaped tube 71, a spray head 72, a water outlet inclined frame 73, a discharge pipe 74, a blockage block 75, and a buoyancy ball 76. One end of the L-shaped tube 71 is connected to and communicates with the connecting long pipe 51. The L-shaped tube 71 passes through the connecting pipe 3. The spray head 72 is fixedly connected to the other end of the L-shaped tube 71 and communicates with the L-shaped tube 71. The water outlet inclined frame 73 is hinged to the bottom of the long heat-conducting pipe 41 and communicates with the long heat-conducting pipe 41. The discharge pipe 74 is connected to the lower part of the water outlet inclined frame 73 and communicates with the water outlet inclined frame 73. The blockage block 75 is slidably connected to the water outlet inclined frame 73. The buoyancy ball 76 is bolted to the blockage block 75.

[0035] Initially, the baffle plate 65 blocked half of the connecting frame 52. In actual operation, the staff first introduced clean water into the water inlet pipe 53, and then introduced the exhaust gas generated by the gas generator set into the connecting pipe 3. The clean water in the water inlet pipe 53 would pass through the connecting frame 52 and the connecting pipe 3 into the circular long frame 2. Several heat-conducting strips 43 would come into full contact with the exhaust gas and conduct the heat from the exhaust gas to the long heat-conducting pipe 41. The long heat-conducting pipe 41 would then conduct the heat from the exhaust gas to the circular long frame 2. The water inside the circular long frame 2 is fully heated. When the circular long frame 2 is full of water, the heated water is introduced into the circular short frame 54 through the arc-shaped pipe 55. The heat-conducting ring 42 transfers the heat from the exhaust gas to the water inside the circular short frame 54, further heating the water and making it more thoroughly heated. The heated water is discharged from the outlet pipe 56, while the heat from the exhaust gas is absorbed by the long heat-conducting pipe 41 and the heat-conducting ring 42. The waste gas that has absorbed heat will be discharged from the long heat-conducting pipe 41, thereby recovering heat from the waste gas by heating clean water using the waste gas generated by the gas generator set. At the same time, the waste gas in the long heat-conducting pipe 41 will impact the swinging bracket 62 and swing it downward. The torsion spring 63 will be twisted. The downward swinging of the swinging bracket 62 will drive the limit rod 64 to rotate upward. The upward rotation of the limit rod 64 will drive the baffle plate 65 and the slotted transmission frame 66 to move upward together. The upward movement of the baffle plate 65 will increase the amount of clean water flowing into the connecting pipe 3. When the amount of waste gas flowing into the pipe is large, the long heat-conducting pipe 41 and the heat-conducting ring 42 can conduct more heat. At the same time, the downward swinging amplitude of the swinging bracket 62 will be greater, resulting in more clean water flowing into the connecting pipe 3. Thus, the amount of clean water flowing into the connecting pipe 3 can be adjusted by the amount of waste gas flowing into the pipe, so that the heat of the waste gas can fully heat the clean water while reducing the waste of waste gas heat and recovering the heat of the waste gas more fully.A portion of the clean water in connecting pipe 3 flows through L-shaped pipe 71 into spray head 72, where it is then sprayed out. The water sprayed from spray head 72 comes into contact with the exhaust gas, flushing down solid impurities and purifying the exhaust gas, thus reducing pollution to the outside environment after discharge. The clean water and impurities flow into the outlet inclined frame 73. As the water level in the outlet inclined frame 73 rises, the buoyancy ball 76 moves upward under the action of buoyancy. The upward movement of the buoyancy ball 76 causes the blocking block 75 to move upward, thus removing the blockage from the outlet. The water outlet frame 73 contains clean water and impurities, which are discharged through the discharge pipe 74. Then, the buoyancy ball 76 and the blocking block 75 reset downwards under gravity, re-blocking the water outlet frame 73. This prevents exhaust gas from leaking from the discharge pipe 74. When exhaust gas is no longer introduced into the connecting pipe 3, clean water is no longer introduced into the inlet pipe 53. The reset of the torsion spring 63 causes the swing lever 62 to swing upwards. The upward swing of the swing lever 62 causes the limit rod 64 to reset. The reset of the limit rod 64 causes the baffle plate 65 and the slotted transmission frame 66 to reset downwards together.

[0036] Example 2

[0037] Based on Example 1, such as Figure 6 As shown, it also includes an auxiliary adsorption component, which is disposed on the heat-conducting ring 42. The auxiliary adsorption component is used to further purify the waste gas. The auxiliary adsorption component includes baffles 81, a drive motor 82, a spur gear ring 83, and a spur gear 84. Several baffles 81 are bolted to the inner wall of the heat-conducting ring 42. The baffles 81 are used to adsorb solid impurities in the waste gas. The drive motor 82 is bolted to the bottom of the connecting pipe 3. The spur gear ring 83 is fixedly connected to the outer wall of the heat-conducting ring 42. The spur gear 84 is connected to the output shaft of the drive motor 82 by a flat key. The spur gear ring 83 is located above the spur gear 84, and the spur gear 84 meshes with the spur gear ring 83.

[0038] Initially, after introducing waste gas and clean water, the staff started the drive motor 82. The rotation of the output shaft of the drive motor 82 drives the spur gear 84 to rotate, which in turn drives the spur gear ring 83 that meshes with it to rotate. The rotation of the spur gear ring 83 drives the heat conduction strip 43 to rotate, which in turn drives several baffles 81 to rotate. The rotation of the baffles 81 allows them to come into full contact with solid impurities in the waste gas and adsorbs the solid impurities onto the baffles 81, thereby further purifying the waste gas and reducing its pollution to the outside world.

[0039] Example 3

[0040] Based on Example 1, such as Figure 6As shown, it also includes a fixing brush 9, which is bolted to the inner wall of the connecting pipe 3.

[0041] As several baffles 81 rotate, they continuously come into contact with the fixed brush 9. The fixed brush 9 cleans the solid impurities adsorbed on the baffles 81, allowing the baffles 81 to continuously adsorb solid impurities in the exhaust gas, thus improving the purification efficiency of the exhaust gas. At the same time, as the heat-conducting ring 42 rotates, the fixed brush 9 also cleans the solid impurities adsorbed on the heat-conducting ring 42, allowing the heat-conducting ring 42 to continuously absorb heat from the exhaust gas, thus improving the heat recovery effect of the exhaust gas. The cleaned solid impurities fall into the water outlet inclined frame 73 and are discharged through the discharge pipe 74.
