Detailed Implementation

[0021] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0022] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0023] like Figures 1-8As shown, an energy-saving, high-efficiency, and emission-reducing boiler includes: a boiler body 1, an exhaust pipe 101 connected to one side of the top of the boiler body 1, a cooling pipe 102 threadedly connected to the outside of the exhaust pipe 101, an air outlet pipe 103 provided at the top of the cooling pipe 102, and a cooling component provided on the outside of the cooling pipe 102 for cooling the flue gas inside the cooling pipe 102. The cooling component includes: a water tank 2, an inlet pipe 201, a drain pipe 202, and a cooling block 203. A cleaning component is provided inside the air outlet pipe 103 for cleaning the dirt on the inner wall of the air outlet pipe 103. The cleaning component includes: a motor 4, a rotating rod 401, and a cleaning plate 402.

[0024] The boiler body 1 has a water tank 2 installed on one side of its top. A water inlet pipe 201 is connected to one side of the top of the water tank 2, and a drain pipe 202 is connected to one side of the outer end of the water tank 2. Multiple cooling blocks 203 are connected to both sides of the inner wall of the cooling pipe 102. When the flue gas generated by the boiler body 1 is discharged from the exhaust pipe 101 into the cooling pipe 102, the water inlet pipe 201 is connected to an external water pipe. Water is then transported to the water tank 2 through the external water pipe and the water inlet pipe 201. The water then exchanges heat with the cooling pipe 102 through its heat absorption properties, thereby cooling the interior of the cooling pipe 102. The activated carbon particles are used to cool the flue gas, thus ensuring the purification effect of the flue gas. The cooling block 203 can block the flow of flue gas in the cooling pipe 102, thereby enhancing the cooling effect of the flue gas. The drain pipe 202 can discharge the water in the water tank 2 and continuously transport water to the water tank 2 through the external water pipe and the water inlet pipe 201, thus circulating the water. This ensures that the water in the water tank 2 can cool the flue gas, and the water that has exchanged heat with the cooling pipe 102 will be heated and can be discharged for use. Therefore, the waste heat of the flue gas can be recovered, achieving the effect of energy saving and environmental protection.

[0025] The water tank 2 has a through hole at the bottom and an opening 3 at the top. A ring-shaped fixing plate 301 is connected to the outside of the cooling pipe 102. A sealing plate 302 is connected to the bottom of the fixing plate 301. When using the device, the bottom end of the cooling pipe 102 is passed through the opening 3 and the through hole and protrudes to the bottom of the water tank 2. Then, the bottom end of the cooling pipe 102 is rotated to the outside of the exhaust pipe 101 until the sealing plate 302 abuts against the inner wall of the water tank 2 and the through hole is blocked. Since the cooling pipe 102 can be disassembled, it can be removed from the top of the boiler body 1 for cleaning or replacement.

[0026] The exhaust pipe 103 is equipped with a motor 4 at the top. The bottom of the motor 4 is connected to a rotating rod 401 via a motor shaft. Cleaning plates 402 are provided on both sides of the outer end of the rotating rod 401. When it is necessary to clean the dirt on the inner wall of the exhaust pipe 103, the motor 4 drives the motor shaft to rotate the rotating rod 401 and the cleaning plate 402. Thus, the dirt on the inner wall of the exhaust pipe 103 is scraped off by the cleaning plate 402, thereby preventing the dirt from affecting the smoke exhaust effect of the exhaust pipe 103.

[0027] The rotating rod 401 has three fixed posts 5 connected to both sides of its outer end. One end of each fixed post 5 has a movable hole 501, and a movable rod 502 is installed inside the movable hole 501. Two springs 503 are installed between one end of the movable rod 502 and the movable hole 501. The other end of the movable rod 502 is connected to the cleaning plate 402. Since the rotating rod 401 and the cleaning plate 402 are connected to the movable rod 502 through the fixed posts 5, the cleaning plate 402 can be rotated by the rotating rod 401. During use, the cleaning plate 402 can push the movable rod 502 and the cleaning plate 402 through the elastic force of the springs 503, so that one side of the cleaning plate 402 can fit against the inner wall of the air outlet pipe 103, thereby ensuring the cleaning effect of the cleaning plate 402 on the dirt on the inner wall of the air outlet pipe 103.

[0028] The air outlet pipe 103 is equipped with a rain shield 6 on top, and a protective shell 601 is installed on top of the rain shield 6. The protective shell 601 is located outside the motor 4. Heat dissipation vents 602 are provided on both sides of the outer end of the protective shell 601, and a baffle 603 is installed on the outer side of the protective shell 601. The rain shield 6 can block rainwater and prevent rainwater from entering the air outlet pipe 103. The protective shell 601 can protect the motor 4, while the heat dissipation vents 602 are used to ensure the heat dissipation of the motor 4, and the baffle 603 is used to prevent rainwater from drifting into the motor 4.

[0029] The exhaust pipe 103 has side plates 7 installed on both sides of its outer end, and the cooling pipe 102 has mounting plates 701 connected to both sides of its outer end. The mounting plate 701 has a threaded hole at its top, and the side plate 7 has a through hole at its top. The through hole is fitted with a bolt that is threaded to the threaded hole. When the cleaning plate 402 scrapes off the dirt from the inner wall of the exhaust pipe 103, the dirt will fall onto the top of the can lid 802. At this time, the bolt is turned out from the threaded hole and the through hole, and the exhaust pipe 103 is separated from the cooling pipe 102. At this time, the dirt on the can lid 802 can be cleaned.

[0030] The cooling pipe 102 has a ring-shaped support block 8 installed inside. A purification tank 801 is set on the top of the support block 8. A tank cover 802 is threadedly connected inside the purification tank 801. A baffle 803 is embedded in the bottom of the purification tank 801 and the top of the tank cover 802. Before using the device, activated carbon particles need to be filled into the purification tank 801. Then, the tank cover 802 is threadedly connected to the top of the purification tank 801. The purification tank 801 is then placed on the cooling pipe 102 and rests on the top of the support block 8. When the harmful gases in the flue gas pass through the baffle 803 and through the purification tank 801 and the tank cover 802, they can be adsorbed by the activated carbon particles. The purified flue gas passes through the cooling pipe 102 and the exhaust pipe 103 and is discharged outside the exhaust pipe 103.

[0031] Working principle:

[0032] When using this device, fill the purification tank 801 with activated carbon granules, then thread the tank cover 802 onto the top of the purification tank 801. Place the purification tank 801 inside the cooling tube 102 and onto the top of the support block 8. Next, pass the bottom end of the cooling tube 102 through the opening 3 and the through hole to the bottom of the water tank 2. Then, rotate the bottom end of the cooling tube 102 to the outside of the exhaust pipe 101 until the sealing plate 302 abuts against the inner wall of the water tank 2 and the through hole is blocked. Then, install the exhaust pipe 103 on the top of the cooling tube 102 through the threaded hole, bolts, and perforations. When the flue gas generated by the boiler body 1 is discharged from the exhaust pipe 101 into the cooling tube 102, connect the water inlet pipe 201 to the external water pipe, and then transport water to the inside of the water tank 2 through the external water pipe and the water inlet pipe 201. Then, the water exchanges heat with the cooling pipe 102 through its heat absorption property, thereby cooling the flue gas inside the cooling pipe 102. This ensures the purification effect of the activated carbon particles on the flue gas. The cooling block 203 can block the flow of flue gas inside the cooling pipe 102, increasing the time and distance of the flue gas flow within the cooling pipe 102, thereby enhancing the cooling effect of the flue gas. The drain pipe 202 can drain the water in the water tank 2 and continuously transport water to the inside of the water tank 2 through the external water pipe and the inlet water pipe 201, thus circulating the water and ensuring that the water in the water tank 2 can cool the flue gas. When it is necessary to clean the dirt on the inner wall of the exhaust pipe 103, the motor 4 drives the motor shaft to rotate the rotating rod 401 and the cleaning plate 402, thereby scraping off the dirt on the inner wall of the exhaust pipe 103 through the cleaning plate 402.
