Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Example 1, please refer to Figure 1-4 The utility model provides a technical solution: a waste heat utilization device for a vacuum hot water boiler, comprising a device body 1, an air intake pipe 101 is fixedly embedded on the left side of the inside of the device body 1 near the top, a joint 102 is fixedly installed on the left side of the air intake pipe 101, a spiral copper tube 103 is fixedly connected to the inside of the air intake pipe 101 near the right side and located inside the device body 1, a plurality of connecting columns 104 are fixedly sleeved on the outer surface of the spiral copper tube 103, the outer sides of the plurality of connecting columns 104 are fixedly installed on the inner wall of the device body 1, the other end of the spiral copper tube 103 is fixedly connected to a first air outlet pipe 105, the outer surface of the first air outlet pipe 105 is fixedly embedded on the right side of the inside of the device body 1, a filter device 106 is fixedly sleeved on the outer surface of the first air outlet pipe 105 near the bottom, a guide plate 107 is fixedly installed on the front side of the inner wall of the filter device 106 and located at the bottom of the first air outlet pipe 105, and a first rotating shaft 108 is movably embedded at the center of the right side of the inside of the filter device 106, A paddle 109 is fixedly sleeved on the outer surface of the first rotating shaft 108 near the bottom of the guide plate 107, a belt 111 is movably sleeved on the right outer surface of the first rotating shaft 108, a second rotating shaft 110 is movably embedded near the bottom at the right center of the filtering device 106, the other end of the belt 111 is movably sleeved on the right outer surface of the second rotating shaft 110, a reciprocating screw 112 is fixedly installed on the left side of the second rotating shaft 110, and the left outer surface of the reciprocating screw 112 is movably embedded in the filtering device 106. On the left side of the inner wall of the device 106, a slider 113 is movably mounted at the center of the outer surface of the reciprocating screw rod 112, and a scraper 114 is fixedly installed at the bottom of the slider 113. Slide grooves 115 are provided on both sides of the inner wall of the filter device 106, and the outer surfaces of both sides of the scraper 114 are slidably connected to the inner surfaces of the slide grooves 115. A filter plate 116 is movably embedded inside the filter device 106 and at the bottom of the scraper 114. A second air outlet pipe 117 is fixedly embedded at the bottom center of the filter device 106.

[0031] In this embodiment, the air intake pipe 101 is first connected to the exhaust pipe of the hot water boiler through the joint 102, so that the smoke enters the spiral copper tube 103 through the air intake pipe 101, and then the smoke is transported from left to right in the spiral copper tube 103. When the smoke is transported to the right side of the spiral copper tube 103, it is transported to the inside of the filter device 106 through the first air outlet pipe 105, so that the smoke flows downward, passes through the filter plate 116, and then is discharged from the second air outlet pipe 117. When the smoke passes through the filter plate 116, the particles and other items contained in the smoke are filtered. When the smoke enters the filter device 106, the smoke is made to flow through the paddle 109 through the guide plate 107, so that when the smoke flows through the paddle 109, the paddle 109 is driven to rotate, and then the paddle 109 is transmitted to the first rotating shaft 108.

When too many particulate matter are filtered out, the filter plate 116 can be pulled out to remove the particulate matter, and through the linkage structure such as the paddle 109 and the filter plate 116, not only can the harmful substances such as particulate matter contained in the flue gas be filtered, thereby reducing pollution to the environment and protecting the air quality and human health, but also the filter plate 116 can be scraped to prevent the filter plate 116 from being blocked and affecting the filtering effect of the device.

[0032] Embodiment 2, as Figure 1-4 As shown, a water inlet pipe 2 is fixedly embedded in the right center of the device body 1 near the top, a water outlet pipe 201 is fixedly embedded in the left center of the device body 1 near the bottom, a one-way valve 202 is fixedly installed inside the water outlet pipe 201, and a support frame 203 is fixedly installed at the bottom center of the device body 1.

[0033] In this embodiment, when the flue gas circulates inside the spiral copper tube 103 on the connecting column 104, cold water can be injected into the device body 1 on the support frame 203 through the water inlet pipe 2, and then the cold water can be heated to recycle the waste heat of the flue gas. After the cold water heating is completed, the one-way valve 202 can be opened to allow hot water to flow out of the device body 1 through the water outlet pipe 201. The setting of the spiral copper tube 103 can increase the circulation time of the flue gas in the spiral copper tube 103, thereby increasing the waste heat recovery effect of the device. The setting of the water inlet pipe 2, the spiral copper tube 103 and other structures can heat the cold water into hot water, thereby realizing the recovery of waste heat inside the flue gas and improving energy utilization efficiency.

[0034] Working principle: When in use, first connect the air intake pipe 101 to the exhaust pipe of the hot water boiler through the joint 102, so that the smoke enters the spiral copper tube 103 through the air intake pipe 101, and then the smoke is transported from left to right in the spiral copper tube 103. When the smoke is transported to the right side of the spiral copper tube 103, it is transported to the inside of the filter device 106 through the first air outlet pipe 105, so that the smoke flows downward, passes through the filter plate 116, and then is discharged from the second air outlet pipe 117. When the smoke passes through the filter plate 116, the particles and other items contained in the smoke are filtered. When the smoke enters the filter device 106, the smoke is made to flow through the paddle 109 through the guide plate 107, so that when the smoke flows through the paddle 109, it drives the paddle 109 to rotate, and then the paddle 109 is transmitted to the first rotating shaft 10 8, when the first rotating shaft 108 rotates, it is transmitted to the second rotating shaft 110 through the belt 111, and then the second rotating shaft 110 drives the reciprocating screw 112 to rotate synchronously, so that when the reciprocating screw 112 rotates, it drives the slider 113 and the scraper 114 to move left and right through the slide groove 115, thereby scraping the particles filtered out on the filter plate 116 to prevent the filter plate 116 from being blocked. When too many particles are filtered out, the filter plate 116 can be pulled out to remove the particles, and through the linkage structure such as the paddle 109 and the filter plate 116, not only can the particles and other harmful substances contained in the flue gas be filtered, the pollution to the environment can be reduced, and the air quality and human health can be protected, but also the filter plate 116 can be scraped to prevent the filter plate 116 from being blocked and affecting the filtering effect of the device. During use, when the flue gas circulates inside the spiral copper tube 103 on the connecting column 104, cold water can be injected into the device body 1 on the support frame 203 through the water inlet pipe 2, and then the cold water is heated to recycle the waste heat of the flue gas. After the cold water heating is completed, the one-way valve 202 can be opened to allow hot water to flow out of the device body 1 through the water outlet pipe 201. The setting of the spiral copper tube 103 can increase the circulation time of the flue gas in the spiral copper tube 103, thereby increasing the waste heat recovery effect of the device. The setting of the water inlet pipe 2, the spiral copper tube 103 and other structures can heat the cold water into hot water, thereby realizing the recovery of waste heat inside the flue gas and improving energy utilization efficiency.
