DETAILED DESCRIPTION
[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0021] like Figures 1 to 6 As shown, the utility model provides an energy waste heat utilization device, including a boiler 1, an air inlet 2 is fixedly installed on the left side of the boiler 1, a smoke exhaust pipe 3 is fixedly installed above the boiler 1, a waste heat recovery bin 4 is sleeved on the outside of the smoke exhaust pipe 3, a water outlet pipe 14 is fixedly installed on the right side of the waste heat recovery bin 4, a limiting ring 15 and a bracket 16 are fixedly installed inside the water outlet pipe 14, a damping rod 17 is fixedly installed on the left side of the bracket 16, a spring 2 18 is sleeved on the outside of the damping rod 17, a sealing plug 19 is fixedly installed on the left side of the spring 2 18, a water inlet pipe 20 is fixedly installed above the waste heat recovery bin 4, and a control valve 21 is rotatably connected to the inside of the water inlet pipe 20.
[0022] The interior of the waste heat recovery bin 4 is hollow, and the exhaust pipe 3 passes through the interior of the waste heat recovery bin 4. When the boiler 1 is burning and heating, the flue gas with heat will be discharged from the inside of the exhaust pipe 3. After passing through the interior of the waste heat recovery bin 4, it will exchange heat with the water inside the waste heat recovery bin 4, thereby achieving the effect of waste heat utilization.
[0023] Among them, the surface of the smoke exhaust pipe 3 is sleeved with a sealing chamber 6, the interior of the sealing chamber 6 is provided with a slide groove 7, the interior of the slide groove 7 is slidably connected with a slider 8, and a collecting plate 9 is fixedly installed above the slider 8. The left side of the sealing chamber 6 is rotatably connected with a sealing cover 13, and the left side of the sealing cover 13 is provided with a lock buckle 5.
[0024] The smoke exhaust duct 3 is located inside the sealed chamber 6 and is communicated with the sealed chamber 6. A filter plate is installed inside the smoke exhaust duct 3. The filter plate is located above the sealed chamber 6. When the smoke is discharged upward, there will be more dust and debris inside, and the discharge into the air will cause air pollution. At this time, the collection plate 9 can collect the dust to reduce the pollution of the smoke discharge.
[0025] Among them, a telescopic rod 10 is fixedly installed on the right side of the collecting plate 9, a spring 11 is sleeved on the outside of the telescopic rod 10, and a limiting plate 12 is fixedly installed on the right side of the spring 11.
[0026] When the collecting plate 9 is installed through the sliding action of the slider 8 and the slide groove 7, the limit plate 12 will rest against the inner side of the sealing chamber 6. When the dust needs to be processed, the collecting plate 9 is pushed to the right, and the spring 11 will provide elastic force to slightly pop the collecting plate 9 outward, thereby facilitating disassembly.
[0027] The interior of the limiting ring 15 is hollow, and the sealing plug 19 is located on the right side of the limiting ring 15 . The diameter of the sealing plug 19 is greater than the diameter of the inner portion of the limiting ring 15 .
[0028] The main function of the sealing plug 19 is to seal the inner side of the limit ring 15. When the water inside the waste heat recovery bin 4 becomes hot, the air pressure will increase. When the air pressure is high, the hot water will be squeezed, squeezing the sealing plug 19 toward the bracket 16. At the same time, the hot water will flow out, allowing the hot water to flow to the designated place.
[0029] Among them, there are two water outlet pipes 14, both of which are located on the right side of the waste heat recovery bin 4, and there are two brackets 16, two damping rods 17 and two springs 18, which are respectively located inside the two water outlet pipes 14.
[0030] The main function of the two damping rods 17 and the two springs 18 is to always provide a large elastic force to the sealing plug 19 so that the sealing plug 19 is always in contact with the right side of the limiting ring 15, so that the inside of the water outlet pipe 14 maintains a sealing effect.
[0031] There are two slide grooves 7 and two sliders 8 , and both the two slide grooves 7 and the two sliders 8 are located inside the sealed chamber 6 .
[0032] The two sliders 8 slide inside the two slide grooves 7 to keep the collecting plate 9 fixed, which facilitates the installation and removal of the collecting plate 9 and the cleaning of the interior of the sealing chamber 6.
[0033] The working principle and use process of this utility model:
[0034] First, connect the air inlet 2 to the igniter, and inject gas into the boiler 1 for combustion. After combustion, a large amount of smoke will be generated inside the boiler 1, and the smoke will be discharged upward through the exhaust pipe 3;
[0035] Secondly, since the interior of the flue gas has a relatively high temperature, after water is injected into the waste heat recovery chamber 4 through the water inlet pipe 20, the flue gas passes through the interior of the exhaust pipe 3, causing the outside of the exhaust pipe 3 to also reach a relatively high temperature. At this time, the water inside the waste heat recovery chamber 4 will be heated, thereby achieving the effect of utilizing the waste heat inside the exhaust pipe 3;
[0036] At this time, since the smoke inside the smoke exhaust pipe 3 contains a large amount of smoke and dust, the smoke and dust will pass through the interior of the waste heat recovery bin 4 along the smoke exhaust pipe 3, and then be discharged upward into the air through the interior of the sealed bin 6 on the left side of the waste heat recovery bin 4. If it is discharged directly, it will cause greater pollution because the smoke contains more smoke and dust. A filter plate is installed inside the smoke exhaust pipe 3, and the smoke and dust will be blocked by the filter plate and fall onto the collection plate 9 located inside the sealed bin 6, so that the collection plate 9 collects the smoke and dust.
[0037] Finally, the collecting plate 9 is disassembled by sliding the slider 8 and the chute 7, and the smoke and dust inside the collecting plate 9 are uniformly processed, thereby achieving the effect of protecting the environment;
