It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.
[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.
[0023] Embodiment 1, as Figure 1-Figure 5 As shown, the utility model provides a boiler two-stage energy saver, including: a water tank 1, both sides of the water tank 1 are fixedly connected with mounting blocks 9, a heat exchange tube 5 is fixedly connected between the outer surfaces of the two mounting blocks 9, both ends of the heat exchange tube 5 are fixedly penetrated through the inner top of the water tank 1 and extend to the outside, one end of the heat exchange tube 5 is fixedly connected with a purification box 6, a slide groove 19 is provided on the rear surface of the purification box 6, a mounting frame 16 is slidably connected to the inner surface of the slide groove 19, an activated carbon filter plate 17 is arranged on the inner surface of the mounting frame 16, a fixing block 13 is fixedly connected to the rear surface of the purification box 6, and the outer surface of the fixing block 13 is symmetrically movable through the fixing block 13. A sliding rod 12, a connecting block 10 is fixedly connected between one end of the two sliding rods 12, a limiting block 14 is fixedly connected between the other ends of the two sliding rods 12, the outer surfaces of the two sliding rods 12 are sleeved with springs 11, a clamping block 15 is fixedly connected to the rear surface of the mounting frame 16, the outer surface of the clamping block 15 is engaged with the inner surface of the limiting block 14, an exhaust pipe 7 is fixedly connected to the top of the purification box 6, one end of the two springs 11 is fixedly connected to the outer surface of the connecting block 10, the other ends of the two springs 11 are fixedly connected to the outer surface of the fixing block 13, and a sealing strip 18 is fixedly connected to the outer surface of the mounting frame 16.
[0024] The effect achieved by the entire embodiment 1 is that, when in use, water is added to the water tank 1 through the water inlet, and then the smoke exhaust pipe of the boiler is connected to the other end of the heat exchange tube 5, so that the smoke of the boiler enters the heat exchange tube 5, thereby the smoke moves in the heat exchange tube 5, and the water in the water tank 1 is heat exchanged, and then the smoke circulates in the heat exchange tube 5 and enters the purification box 6 along the tail end of the heat exchange tube 5, so that the harmful gases and pollutants in the smoke are adsorbed and removed by the activated carbon filter plate 17, and then discharged through the exhaust pipe 7. By purifying the smoke and then discharging it, the pollution to the environment is reduced, the emission of harmful substances is reduced, and the air quality is improved. At the same time, after long-term use, the staff can push the connecting block 10 outward to drive the sliding rod 12 to slide on the fixed block 13, so that the limit block 14 moves outward, so that the limit block 1 4 is no longer engaged with the card block 15, and then the mounting frame 16 is taken out of the purification box 6 by pulling the card block 15 outward, so that the activated carbon filter plate 17 can be quickly replaced.

[0026] The effect achieved by the entire embodiment 2 is that the temperature of the water in the water tank 1 can be monitored in real time by the thermometer 8, and at the same time the pipeline pump 2 is started, the water in the water tank 1 is extracted through the connecting pipe 3 and then discharged through the drain pipe 4 for utilization, and the heat exchange tube 5 is made of 36 ф32 seamless steel pipes, with a length of 70 cm, an elbow height of 10 cm, and a total area of 80 cm*80 cm, which are welded in an oblique manner to ensure that the heat fully covers the tube surface and increase the heat exchange effect of the heat exchange tube 5.
[0027] Working principle: When in use, water is added to the water tank 1 through the water inlet, and then the exhaust pipe of the boiler is connected to the other end of the heat exchange tube 5, so that the smoke of the boiler enters the heat exchange tube 5, so that the smoke moves in the heat exchange tube 5 to exchange heat with the water in the water tank 1, and then the pipeline pump 2 can be started, and the water in the water tank 1 is extracted through the connecting pipe 3 and then discharged through the drain pipe 4 for utilization, and then the smoke circulates in the heat exchange tube 5 and enters the purification box 6 along the tail end of the heat exchange tube 5, so that the harmful gases and pollutants in the smoke are adsorbed and removed by the activated carbon filter plate 17, and then discharged through the exhaust pipe 7. By purifying the smoke and then discharging it, the pollution to the environment is reduced, the emission of harmful substances is reduced, and the air quality is improved. At the same time, after long-term use, the staff can push the connecting block 10 outward to drive the sliding rod 12 to slide on the fixed block 13, so that The limiting block 14 moves outward so that the limiting block 14 is no longer engaged with the card block 15, and then the mounting frame 16 is taken out of the purification box 6 by pulling the card block 15 outward, so that the activated carbon filter plate 17 can be quickly replaced. When the replacement is completed and needs to be installed, the connecting block 10 is pulled outward, so that the sliding rod 12 and the limiting block 14 move outward along the fixing block 13, and the spring 11 is stretched, and then the mounting frame 16 is inserted into the purification box 6 along the slide groove 19. When the insertion is completed, the connecting block 10 is released, and the restoring force of the spring 11 when it rebounds is used to reset the connecting block 10, so that the sliding rod 12 and the limiting block 14 move inward, so that the limiting block 14 is engaged with the card block 15, and at the same time, the sealing strip 18 is squeezed to produce deformation to fill the connection between the mounting frame 16 and the slide groove 19 to ensure the sealing, so that the activated carbon filter plate 17 can be quickly replaced to ensure the purification effect of the flue gas.
