[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] like Figure 1-5 As shown, a boiler waste heat high-efficiency utilization device includes a boiler body 1, a smoke pipe 2 fixedly connected to the top of the boiler body 1, a smoke chamber 3 arranged on the outside of the boiler body 1, a cover plate 4 fixedly connected to the top of the smoke chamber 3, a flue pipe 5 fixedly connected to the outside of the smoke chamber 3, a water tank 6 fixedly connected inside the smoke chamber 3, a water filling pipe 7 fixedly connected to the top of the water tank 6, a drain pipe 8 fixedly connected to the outer periphery of the water tank 6, a water vapor heat energy utilization mechanism 9 arranged on the top of the smoke chamber 3, and a filtration mechanism 10 arranged on the outside of the smoke chamber 3.

[0027] The water vapor heat energy utilization mechanism 9 includes an insulation jacket 90, a spiral guide plate 91, and a water vapor pipe 92. The inner side of the insulation jacket 90 is fixedly connected to the outer periphery of the smoke pipe 2. The inner side of the spiral guide plate 91 is fixedly connected to the outer periphery of the water tank 6. The bottom of the water vapor pipe 92 is fixedly connected to the top of the water tank 6. A preheating pipe 94 is fixedly connected to the output end of the water vapor pipe 92. An installation plate 93 is fixedly connected to the outer side of the preheating pipe 94.

[0028] It should be noted that the smoke enters the smoke chamber 3 through the smoke pipe 2, and the spiral guide plate 91 increases the time the smoke stays in the smoke chamber 3, thus fully heating the water in the water bucket 6. After the water is heated, the water vapor generated by the hot water enters the preheating pipe 94 through the steam pipe 92. After the preheating pipe 94 is heated, it can heat other items.

[0029] The filtration mechanism 10 includes a housing 100, which is fixedly connected to the outside of the exhaust pipe 5. An activated carbon filter element 101 is slidably connected inside the housing 100. A baffle 102 is slidably connected inside the housing 100. A mounting shell 103 is fixedly connected to the top of the housing 100. A moving block 104 is slidably connected inside the mounting shell 103. A snap-fit ​​block 105 is fixedly connected inside the moving block 104. A first spring 106 is sleeved on the outer periphery of the snap-fit ​​block 105. A pull block 107 is fixedly connected to one end of the snap-fit ​​block 105. A limit block 108 is slidably connected inside the moving block 104. A second spring 109 is provided on the outer side of the limit block 108.

[0030] It should be noted that the smoke in the smoke chamber 3 enters the filter mechanism 10 through the exhaust pipe 5. First, it adsorbs harmful substances through the activated carbon filter element 101. When the filter element needs to be replaced, the limiting block 108 is pulled, and the limiting block 108 pulls the second spring 109, causing the second spring 109 to generate elastic force. After the limiting block 108 slides out from inside the moving block 104, the pulling block 107 is pulled to release the limiting block 108. The locking block 105 drives the moving block 104 to compress the first spring 106. The pulling block 107 drives the locking block 105 to slide out from inside the baffle 102. At this time, the baffle 102 can be removed to replace the activated carbon filter element 101. After the replacement is completed, the baffle 102 is installed inside the outer shell 100. The limiting block 108 is pulled again, and the limiting block 108 releases the limiting of the moving block 104. The first spring 106 pushes the moving block 104 to reset and fix the baffle 102.

[0031] like Figure 1 , Figure 2 As shown, the end of the smoke pipe 2 away from the boiler body 1 is fixedly connected to the top of the cover plate 4, and the outer periphery of the exhaust pipe 5 is fixedly connected to the inside of the smoke chamber 3.

[0032] It should be noted that the end of the smoke pipe 2 away from the boiler body 1 is fixedly connected to the top of the cover plate 4, so that the smoke pipe 2 can transport smoke into the smoke chamber 3. The outer periphery of the exhaust pipe 5 is fixedly connected to the inside of the smoke chamber 3, so that the exhaust pipe 5 can discharge smoke.

[0033] like Figure 1 , Figure 2 As shown, the water inlet pipe 7 is fixedly connected to the inside of the cover plate 4, and the drain pipe 8 is fixedly connected to the inside of the smoke chamber 3.

[0034] It should be noted that the water inlet pipe 7 is fixedly connected to the inside of the cover plate 4, so that the water inlet pipe 7 is installed stably, and the drain pipe 8 is fixedly connected to the inside of the smoke chamber 3, so that the drain pipe 8 is installed stably.

[0035] like Figure 1 , Figure 2 As shown, the water vapor pipe 92 is fixedly connected to the inside of the cover plate 4 on its outer periphery.

[0036] It should be noted that the outer periphery of the water vapor pipe 92 is fixedly connected to the inside of the cover plate 4, so that the water vapor pipe 92 is installed stably.

[0037] like Figure 1 , Figure 3 , Figure 4 , Figure 5 As shown, the snap-fit ​​block 105 is slidably connected to the inside of the mounting shell 103 on the outside, and the limiting block 108 is slidably connected to the inside of the mounting shell 103 on the outside.

[0038] It should be noted that the outer side of the snap-fit ​​block 105 is slidably connected to the inside of the mounting shell 103, allowing the snap-fit ​​block 105 to be pulled freely. The outer side of the limiting block 108 is slidably connected to the inside of the mounting shell 103, allowing the limiting block 108 to limit and snap the moving block 104, preventing the snap-fit ​​block 105 from moving accidentally.

[0039] As shown in the figure, one end of the first spring 106 is fixedly connected to the outside of the moving block 104, and the other end of the first spring 106 is fixedly connected to the inside of the mounting shell 103.

[0040] It should be noted that the connection method of the first spring 106 allows the first spring 106 to be compressed by the moving block 104 to generate elastic force, and the auxiliary locking block 105 to be reset.

[0041] As shown in the figure, one end of the second spring 109 is fixedly connected to the outside of the mounting shell 103, and the other end of the second spring 109 is fixedly connected to the outside of the limiting block 108.

[0042] It should be noted that the connection method of the second spring 109 allows the second spring 109 to be stretched by the limiting block 108 to generate elastic force, which assists the limiting block 108 in resetting.

[0043] The working principle of this utility model is as follows: The smoke generated by the boiler body 1 enters the smoke chamber 3 through the smoke pipe 2. The spiral guide plate 91 increases the residence time of the smoke inside the smoke chamber 3, thus fully heating the water in the water tank 6. After the water is heated, the steam generated by the hot water enters the preheating pipe 94 through the steam pipe 92. After the preheating pipe 94 is heated, it can heat other items. The smoke in the smoke chamber 3 enters the filter mechanism 10 through the exhaust pipe 5. First, it adsorbs harmful substances through the activated carbon filter element 101. When the filter element needs to be replaced, the limiting block 108 is pulled. The limiting block 108 pulls the second spring 109, causing the second spring 109 to generate elastic force. After the limiting block 108 slides out from inside the moving block 104, pull the pull block 107 to release the limiting block 108. The locking block 105 drives the moving block 104 to compress the first spring 106. The pull block 107 drives the locking block 105 to slide out from inside the baffle 102. At this time, the baffle 102 can be removed to replace the activated carbon filter element 101. After the replacement is completed, the baffle 102 is installed inside the outer shell 100. Pull the limiting block 108 again to release the limiting block 108 from the moving block 104. The first spring 106 pushes the moving block 104 to reset and fix the baffle 102. The water pipe 7 can add water to the inside of the water tank 6, and the drain pipe 8 can take out hot water for use.
