Description

Technical Field

[0001] The utility model relates to the technical field of steam generators, in particular to an exhaust gas waste heat recovery type steam generator. Background Art

[0002] A steam generator is an energy conversion device. Its main working principle is to use the heat energy released after fuel combustion or the waste heat in industrial production to transfer to the water in the container, so that the water reaches the required temperature or a certain pressure steam.

[0003] A type of exhaust gas waste heat recovery steam generator currently in use mostly uses straight heat exchange tubes to absorb waste heat in the exhaust gas. This method has poor heat exchange efficiency, is not conducive to heat conduction, and reduces energy utilization. At the same time, due to the long-term contact between the flue gas and the heat exchange tube, dust and scaling are generated on the outside of the heat exchange tube, which affects the contact effect between the flue gas and the heat exchange tube and reduces the practicality of the steam generator.

[0004] In summary, the present invention solves the problems in the above-mentioned background technology by designing an exhaust gas waste heat recovery steam generator. Utility Model Content

[0005] The purpose of the present invention is to provide an exhaust gas waste heat recovery steam generator to solve the problems raised in the above background technology.

[0028] A waste heat recovery steam generator includes a device body 1, a fixed base 2 is provided at the bottom of the device body 1, an exhaust pipe 3 is provided at the top of the device body 1, an inlet 4 is provided at the rear end of the outer side of the device body 1, a recovery tank 5 is fixedly installed at the right end of the outer side of the device body 1, a mounting support 6 is provided on the top of the recovery tank 5, a plate groove 601 is provided on the outer surface of the mounting support 6, a dust filter plate 602 is provided inside the plate groove 601, a guide block 603 is fixedly installed on the right side of the dust filter plate 602, a socket 6031 is provided on the top surface of the guide block 603, an insertion rod 604 is fitted through the top surface of the mounting support 6, an air outlet 501 is provided at the bottom end of the front side of the recovery tank 5, and a waste heat recovery mechanism 7 is provided inside the recovery tank 5;

[0029] Specifically, the end of the exhaust pipe 3 away from the device body 1 passes through the top surface of the mounting bracket 6 and is connected to the interior thereof. The inner bottom end of the mounting bracket 6 extends to the interior of the recovery tank 5. The outer surface of the smoke filter plate 602 is in sealing contact with the inner wall of the plate groove 601. The bottom end of the insertion rod 604 extends to the interior of the plate groove 601 and is plugged into the socket 6031.

[0030] In this embodiment, the exhaust pipe 3 is provided to allow the exhaust gas generated by the device body 1 to enter the recovery tank 5. When the smoke filter plate 602 is in contact with the exhaust gas, the smoke particles in the exhaust gas can be blocked. The insertion rod 604 is provided to make it contact or disengage with the socket 6031, thereby achieving the purpose of installing and disassembling the smoke filter plate 602, ensuring the filtering effect, and effectively avoiding the accumulation of dust and scaling on the outer surface of the guide tube 703.

[0031] In this embodiment, please refer to Figure 1 and Figure 3 The waste heat recovery mechanism 7 includes a water inlet 701, a water outlet 702 and a guide pipe 703. The water inlet 701 and the water outlet 702 are fixedly arranged on the rear surface of the recovery tank 5. The guide pipe 703 is arranged inside the recovery tank 5, and its outer surface is provided with heat conducting fins 704.

[0032] Specifically, both ends of the guide tube 703 penetrate the inner wall of the recovery tank 5 and are connected to the water inlet 701 and the water outlet 702. The guide tube 703 is arranged in a serpentine shape. The heat conducting fins 704 are evenly spaced about the outer surface of the guide tube 703. The guide tube 703 and the heat conducting fins 704 are both made of copper.

The provision of the heat-conducting fins 704 further enhances heat conduction, ensuring that the heat in the exhaust gas is fully absorbed, thereby improving the heat recovery efficiency of the steam generator.

[0034] The working process of the present utility model is as follows: when a waste heat recovery steam generator is used, the device body 1 will generate waste gas when the steam generator is working, and the waste gas enters the interior of the mounting bracket 6 through the waste gas pipe 3 and contacts the smoke filter plate 602. At this time, the smoke filter plate 602 filters the smoke particles in the waste gas, and the waste gas after filtering enters the recovery tank 5 and contacts the guide pipe 703 and the heat conducting fins 704. At this time, water is injected into the guide pipe 703 through the water inlet 701, and the heat in the waste gas is then conducted to the guide pipe 703 and absorbed by the water, thereby realizing the recovery of heat energy in the waste gas and improving the energy utilization efficiency of the steam generator. Furthermore, by clamping the plug rod 604 and the socket 6031, the smoke filter plate 602 can be easily disassembled, thereby ensuring the filtering effect and meeting the needs of users.
