[0003] The utilization of waste heat from high-temperature flue gas in generator sets is mainly adapted to the production process of boiler hot water. However, high-temperature flue gas contains unburned combustible components. If these components are not fully burned, they will cause the loss of heat energy. At the same time, when these components adhere to the components that conduct heat energy in the boiler, the boiler's efficiency in collecting and transferring heat energy will be reduced.

[0004] In view of this, a waste heat recovery and utilization device for generator sets was designed to solve the above problems. Utility Model Content

[0032] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0033] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0034] The following describes, with reference to the accompanying drawings, some embodiments of a generator set waste heat recovery and utilization device provided by this utility model. Example 1

[0035] Combination Figures 1-7As shown, the present invention provides a generator set waste heat recovery and utilization device, including a flue gas transfer assembly 100 installed on the generator set exhaust pipe, a heat preservation assembly 200 installed on the flue gas transfer assembly 100, and a preheating utilization mechanism 300 installed in the heat preservation assembly 200. The flue gas transfer assembly 100 is used to collect the high-temperature flue gas generated by the generator set, the heat preservation assembly 200 is used to keep the released heat energy warm, and the preheating utilization mechanism 300 is used to collect and utilize the heat energy of the flue gas and the heat energy of the secondary combustion of combustible components.

[0036] The flue gas transfer assembly 100 includes six sets of combined bolts 120 and a reinforcing end tube 130, and multiple discharge electrode posts 150 disposed within the reinforcing end tube 130;

[0037] The smoke pipe 110 is set at the bottom of the reinforcing end tube 130, and the protective outer tube 140 is set on each of the multiple discharge electrode posts 150;

[0038] Multiple discharge electrode posts 150 are connected to a connector that extends into the inner cavity of the protective outer tube 140, and the other end of the wire 160 extends into the outer cavity of the protective outer tube 140.

[0039] The heat insulation component 200 includes an insulated outer pot 210 disposed on the top of the reinforcing end tube 130 and a sealing cap 230 disposed on the top of the insulated outer pot 210.

[0040] Six sets of combination bolts 120 are installed in the two adjacent ends of the flue pipe 110 and the heat-insulating outer pot 210;

[0041] The preheating and utilization mechanism 300 includes a storage inner pot 310 disposed inside the heat-insulating outer pot 210, a base 340 mounted on the bottom of the storage inner pot 310, and a heat collection component 350 disposed inside the base 340 and extending into the storage inner pot 310.

[0042] The heat collection assembly 350 is provided with multiple fins 360 evenly distributed.

[0043] As the generator set is running, the high-temperature flue gas it produces will be affected by the airflow and descend, carrying away and releasing some combustible components. If these combustible components are not fully combusted, they will cause the loss of energy and thus reduce the effective utilization of waste heat.

[0044] When the flue pipe 110 gathers the high-temperature flue gas generated by the generator set, the combustible components in the high-temperature flue gas flow through the airflow into the inner cavity of the reinforced end pipe 130. The multiple discharge electrode columns 150, which are in continuous discharge, can then burn the combustible components a second time. At this time, the heat energy generated by the combustible components can be collected by the heat release pipe 351 along with the heat energy in the flue gas, and then released into the solution in the inner cavity of the storage pot 310 through the evenly distributed multiple fins 360. At this time, the device can replace the traditional boiler and improve the effective utilization rate of the heat energy in the flue gas.

[0045] After the heat dissipation tube 351 has been used for a period of time, the traction rod 355 is pulled up by controlling the exhaust pipe 370 and the clamp 380. At this time, the filter screen 354 and scraper head 353 installed on the bottom column of the traction rod 355 can scrape off the carbon deposits on the inner wall of the heat dissipation tube 351, thereby improving the cleanliness of the inner wall of the heat dissipation tube 351. Example 2

[0046] Combination Figure 2 and Figure 4 As shown, based on Embodiment 1, the heat preservation component 200 also includes a pressure-bearing neck sleeve 220, which is fixedly installed at the bottom of the inner cavity of the heat-insulating outer pot 210, and the top of the pressure-bearing neck sleeve 220 is provided with a bevel adapted to be supported on the bottom of the storage inner pot 310.

[0047] Preferably, the surface of the pressure-bearing neck sleeve 220 is coated with flame-retardant and heat-insulating profiles, which on the one hand improves the support strength of the storage inner pot 310, and on the other hand can concentrate and transfer heat energy.

[0048] The inner wall of the heat-insulating outer pot 210 is coated with heat-insulating paint.

[0049] The bottom surface of the sealing cover 230 is provided with an insulation layer.

[0050] Preferably, the gap formed by the heat-insulating outer pot 210 and the storage inner pot 310 can be filled with a flame-retardant heat-insulating pad to provide high heat insulation protection for the storage inner pot 310, while also providing pressure resistance protection for the storage inner pot 310. Example 3

[0051] Combination Figures 3-7 As shown, in the above embodiment, the preheating and utilization mechanism 300 also includes a water inlet pipe 320 disposed on the top of the storage inner pot 310, and a drain pipe 330 disposed on the bottom of the storage inner pot 310.

[0052] Preferably, valves can be installed at the outer ends of the inlet pipe 320 and the outlet pipe 330, depending on the actual usage requirements, for precise control of the inlet and outlet flow rates.

[0053] The heat collection assembly 350 includes a heat dissipation pipe 351, and an exhaust pipe 370 is provided on the threaded section at the top of the heat dissipation pipe 351. A clamp 380 is installed inside the exhaust pipe 370.

[0054] A gasket 352 is installed at the bottom end of the heat dissipation tube 351, a traction rod 355 is installed inside the clamp 380, a filter screen 354 is installed on the column at the bottom end of the traction rod 355, and a scraper 353 is installed on the outside of the filter screen 354.

[0055] The top and bottom of the scraper 353 are provided with annular blades that fit and conform to the inner wall of the heat dissipation tube 351.

[0056] Preferably, the assembly of the threaded section at the top of the heat-dissipating tube 351 and the exhaust pipe 370 is only one way to secure the top of the traction rod 355. Depending on the usage requirements, the exhaust pipe 370 can be movably inserted into the top of the heat-dissipating tube 351, and hydraulic equipment can be used to provide traction power to the exhaust pipe 370, the clamp 380, and the lifting rod of the traction rod 355, thereby improving the self-cleaning of carbon deposits on the inner wall of the heat-dissipating tube 351 by the scraper head 353.

[0057] The working principle and usage process of this utility model: The flue pipe 110 is connected to the exhaust pipe of the generator set in advance. As the generator set runs and continuously releases high-temperature flue gas, the high-temperature flue gas will be transferred from the inner cavity of the flue pipe 110 to the reinforced end pipe 130, the pressure-bearing neck sleeve 220 and the heat-releasing pipe 351 that form a passage.

[0058] During this process, when the wire 160 is energized, it will discharge from the multiple evenly distributed discharge electrode posts 150. At this time, the non-combustible components that have passed through the inner cavity of the reinforced end tube 130 can be fully burned under the discharge state of the multiple discharge electrode posts 150. Finally, the heat energy in the flue gas will be released from the heat release tube 351 to the multiple fins 360.

[0059] After the water inlet pipe 320 injects the aqueous solution into the inner cavity of the storage inner pot 310, the drain pipe 330 is closed by the external valve. At this time, the heat release pipe 351 and multiple fins 360, which are continuously releasing heat, can heat the aqueous solution in the inner cavity of the storage inner pot 310. The storage inner pot 310, which is sealed by the heat-insulating outer pot 210 and the sealing cover 230, can be in a high heat preservation state.

[0060] After a certain period of use, by loosening the exhaust pipe 370 and cooperating with the clamp 380 to pull the traction rod 355, the filter screen 354 and scraper head 353, which are then pulled, can scrape off the carbon deposits on the inner wall of the heat release pipe 351, thereby ensuring that the heat energy in the flue gas can be efficiently transferred by the heat release pipe 351, and also utilizing the secondary combustion heat energy of the combustible components in the flue gas.
