Abstract
Description
Technical Field
[0001] This utility model relates to the field of generator auxiliary equipment technology, specifically a waste heat recovery and heat dissipation structure for generator sets. Background Technology
[0002] A generator is a device that converts mechanical energy or other renewable energy sources (such as hydropower, wind power, fuel oil, etc.) into electrical energy. This device can operate independently or be used in parallel, and is not affected by grid failures. It is widely used in emergency power supply, industrial production and renewable energy applications. During the operation of fuel oil generator sets, a large amount of high-temperature exhaust gas is generated. If it is directly discharged, it will not only waste energy, but also affect the heat dissipation efficiency of the equipment. Therefore, the waste heat of the generator set is usually recovered and utilized.
[0003] Currently, when using waste heat recovery devices to recover waste heat, they mainly rely on heat exchange devices. However, existing technologies mostly use single-stage exchange treatment, resulting in the temperature of the treated exhaust gas still being relatively high. This leads to heat waste during discharge, thereby reducing the waste heat recovery effect. Therefore, a waste heat recovery and heat dissipation structure for generator sets is needed to solve the above problems. Utility Model Content
[0004] The purpose of this utility model is to provide a waste heat recovery and heat dissipation structure for generator sets, so as to solve the problems mentioned in the background art. To solve the above technical problems, this utility model is achieved through the following technical solution:
[0005] This utility model relates to a waste heat recovery and heat dissipation structure for generator sets, comprising:
[0006] Waste heat recovery box;
[0007] A partition plate is fixedly installed inside the waste heat recovery box, and the partition plate divides the inside of the waste heat recovery box into two recovery chambers;
[0008] The first heat exchange tube is disposed inside one of the recovery chambers, and a plurality of heat-conducting fins are fixedly provided on the outer wall of the first heat exchange tube.
[0009] The second heat exchange tube is disposed inside another recovery chamber. The second heat exchange tube is S-shaped and is connected to the opposite end of the first heat exchange tube.
[0010] Furthermore, the bottom ends of the two recycling chambers are connected to a water inlet pipe, and the top ends of the two recycling chambers are respectively connected to a drain pipe.
[0011] Furthermore, the other end of the first heat exchange tube is connected to a processing tube, and the other end of the second heat exchange tube is connected to an exhaust pipe.
[0012] Furthermore, the outer walls of the first heat exchange tube and the second heat exchange tube respectively penetrate both sides of the waste heat recovery box.
[0013] Furthermore, it also includes a filter component, which includes a filter plate. The outer wall of the filter plate is fixedly disposed inside the processing tube. A connecting shaft is provided through one side of the filter plate. A scraper is fixedly disposed at one end of the outer wall of the connecting shaft. A fan blade is sleeved on the outer wall of the connecting shaft.
[0014] Furthermore, the filter component also includes a vertical rod, the top end of which is fixedly disposed at the inner top end of the processing tube, and the bottom end of one side of the vertical rod is rotatably connected to one end of the connecting shaft.
[0015] Furthermore, a collection box is connected to the bottom end of the processing tube.
[0016] This utility model has the following beneficial effects:
[0017] This invention utilizes a partition plate, a first heat exchange tube, and a second heat exchange tube. The partition plate divides the waste gas recovery box into two recovery chambers, where heat exchange occurs between the first and second heat exchange tubes and the cooling water in each chamber. This staged waste gas heat exchange treatment enables tiered heat recovery, preventing heat waste during emission and improving waste heat recovery efficiency. Furthermore, by installing heat-conducting fins on the first heat exchange tube and arranging the second heat exchange tube in an S-shape, the heat exchange performance between the waste gas and the cooling water in the recovery chamber is further enhanced, thus improving the waste heat recovery effect.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.
[0027] Please see Figure 1-4 As shown, this utility model is a waste heat recovery and heat dissipation structure for a generator set, comprising:
[0028] Waste heat recovery box 11;
[0029] Waste heat recovery box 11 is used for waste heat recovery and is filled with cooling water.
[0030] The partition plate 12 is fixedly installed inside the waste heat recovery box 11 and divides the inside of the waste heat recovery box 11 into two recovery chambers 111.
[0031] The first heat exchange tube 13 is disposed inside one of the recovery chambers 111, and a plurality of heat-conducting fins 131 are fixedly provided on the outer wall of the first heat exchange tube 13.
[0032] Several heat-conducting plates 131 are arranged in a cross shape to improve the heat exchange efficiency of the first heat exchange tube 13.
[0033] The second heat exchange tube 14 is disposed inside another recovery chamber 111. The second heat exchange tube 14 is generally S-shaped, and the opposite end of the second heat exchange tube 14 and the first heat exchange tube 13 are connected.
[0034] The first heat exchange tube 13, the second heat exchange tube 14, and the heat-conducting plate 131 are made of copper tube and copper plate, respectively, which can increase their heat conduction effect. The S-shaped second heat exchange tube 14 can reduce the transmission time of the exhaust gas in the second heat exchange tube 14, thereby improving the heat exchange effect between the exhaust gas and the water in the recovery chamber 111.
[0035] The bottom ends of the two recycling chambers 111 are connected to a water inlet pipe 19, and the top ends of the two recycling chambers 111 are respectively connected to a drain pipe 15.
[0036] The inlet pipe 19 is used to input cooling water into the recovery chamber 111, and the drain pipe 15 is used to discharge the cooling water after heat exchange in the recovery chamber 111 to the outside.
[0037] The other end of the first heat exchange tube 13 is connected to a processing tube 16, and the other end of the second heat exchange tube 14 is connected to an exhaust pipe 17.
[0038] The treatment pipe 16 and its internal connecting parts are all treated to withstand high temperatures and are regularly inspected. The treatment pipe 16 is connected to the exhaust pipe of the generator set.
[0039] The outer walls of the first heat exchange tube 13 and the second heat exchange tube 14 respectively penetrate both sides of the waste heat recovery box 11;
[0040] The first heat exchange tube 13 and the second heat exchange tube 14 are fixedly connected to both sides of the waste heat recovery box 11.
[0041] Working principle: First, cooling water is injected into the two recovery chambers 111 through the water inlet pipe 19. The high-temperature exhaust gas generated by the generator set is input into the treatment pipe 16 and then into the first heat exchange pipe 13. With the help of the heat-conducting plate 131, the high-temperature exhaust gas in the first heat exchange pipe 13 exchanges heat with the cooling water in the recovery chamber 111 where the first heat exchange pipe 13 is located. Next, the exhaust gas after heat exchange enters the second heat exchange pipe 14 from the first heat exchange pipe 13 and exchanges heat again with the cooling water in the recovery chamber 111 where the second heat exchange pipe 14 is located. Finally, it is discharged from the exhaust pipe 17. Through this staged exhaust gas heat exchange treatment, heat can be recovered in stages, thus avoiding heat waste during discharge and improving the waste heat recovery effect.
[0042] Please see Figure 1-4 As shown, this embodiment, based on the above embodiment, further includes:
[0043] The filter component includes a filter plate 21. The outer wall of the filter plate 21 is fixedly disposed inside the processing tube 16. A connecting shaft 22 is provided through one side of the filter plate 21. A scraper rod 23 is fixedly disposed at one end of the outer wall of the connecting shaft 22. A fan blade 24 is sleeved on the outer wall of the connecting shaft 22.
[0044] The filter plate 21 is used to filter high-temperature exhaust gas. The scraper rod 23 contacts one side of the filter plate 21, and the size of the scraper rod 23 is adapted to the size of the filter plate 21.
[0045] The filter component also includes a vertical rod 25, the top end of which is fixedly installed at the inner top end of the treatment tube 16, and the bottom end of one side of the vertical rod 25 is rotatably connected to one end of the connecting shaft 22.
[0046] The vertical rod 25 is used to provide rotational support for the connecting shaft 22, thereby improving the overall stability when the connecting shaft 22 rotates.
[0047] The bottom end of the processing tube 16 is connected to a collection box 18;
[0048] The collection box 18 is used to collect the waste scraped off the filter plate 21. The bottom of the collection box 18 is hinged with a bottom cover, which facilitates the treatment of the waste in the collection box 18.
[0049] Working principle: When high-temperature exhaust gas enters the treatment pipe 16, it will first be filtered by the filter plate 21. After the filtered exhaust gas passes through the fan blade 24, the fan blade 24 will rotate under the action of the high-temperature airflow. The rotation of the fan blade 24 drives the scraper rod 23 to rotate through the connecting shaft 22, so that it scrapes off the waste on the filter plate 21. The filter plate 21 can filter the high-temperature exhaust gas generated by the generator set, and prevent solid particles in the exhaust gas from adhering to the inner wall of the heat exchange tube and reducing its heat exchange effect. At the same time, the process of air transportation can also drive the scraper rod 23 to rotate, thereby realizing the self-cleaning of the filter plate 21.
