Abstract
Description
Technical Field
[0001] This utility model relates to the field of boiler technology, specifically a novel boiler carbon emission reduction device. Background Technology
[0002] Boilers are important energy conversion devices, widely used in industries such as power, heating, and petrochemicals. In my country, various types of boilers consume approximately 2 billion tons of standard coal equivalent annually, accounting for about 40% of the country's total carbon emissions. They are the most energy-intensive and carbon-emitting equipment, thus requiring the use of carbon reduction devices to decrease their carbon emissions.
[0003] Common carbon emission reduction devices consist of a treatment chamber, a flue, and a spraying device. In use, flue gas is introduced into the treatment chamber through the flue, and then denitrification agents or other treatment agents are sprayed through the spraying device, so that they react with the flue gas, thereby purifying the harmful gases in the flue gas and achieving the purpose of carbon emission reduction.
[0004] However, this method is only a simple static mixing or two-dimensional plane mixing, which limits the contact area between flue gas and denitrification agent in the treatment box and makes it impossible to fully mix in three-dimensional space, thus affecting the reaction efficiency and ultimately affecting the purification effect of the carbon emission reduction device on the flue gas, failing to meet the working requirements of the boiler. Therefore, a new type of boiler carbon emission reduction device is proposed. Utility Model Content

[0020] Beneficial effects:
[0021] This novel boiler carbon emission reduction device uses a first motor to drive a rotating shaft, which in turn rotates both square and circular levers. Simultaneously, a second motor drives a cam, which in turn moves the first motor and the rotating shaft up and down via a mounting plate.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0029] This utility model provides a technical solution: a novel boiler carbon emission reduction device, comprising a boiler 1, a processing box 2, a flue pipe 3, a water tank 4, a rotating shaft 5, an atomizing nozzle 6, a square lever 7, a circular lever 8, a water pump 9, a water pipe 10, a connecting frame 11, an assembly rod 12, a mounting plate 13, a first motor 14, a second motor 15, a cam 16, a spring 17, a flue pipe 18, and a water injection pipe 19.
[0030] Please see Figure 1 Boiler 1, with a treatment box 2 installed on its left side, and a flue pipe 3 installed on the top left side of boiler 1, the outlet of which is connected to the inner cavity of the treatment box 2. A water tank 4 is installed at the rear of the treatment box 2. Please refer to [link / reference]. Figure 3 A water pipe 10 is inserted inside the water tank 4. The water pipe 10 is L-shaped. A water pump 9 is installed at the rear of the treatment box 2, corresponding to the position of the atomizing nozzle 6. The outlet of the water pipe 10 is connected to the inlet of the water pump 9.
[0031] Please see Figure 2 A rotating shaft 5 is inserted into the upper part of the inner cavity of the processing box 2. A square paddle 7 is coaxially mounted on the outside of the rotating shaft 5, and a circular paddle 8 is coaxially mounted on the outside of the rotating shaft 5 between the square paddles 7.
[0032] Please see Figure 4 Assembly rod 12 is connected to the top two sides of the processing box 2. Mounting plate 13 is sleeved on the outside of assembly rod 12. (See attached image.) Figure 5 The first motor 14 is installed at the bottom center of the mounting plate 13, and the bottom end of the rotor of the first motor 14 is coaxially connected to the top end of the rotating shaft 5.
[0033] Please see Figure 4 The connecting frame 11 is welded to the front and rear sides of the top of the treatment box 2. A second motor 15 is mounted on the rear side of the connecting frame 11 via a bracket. A cam 16 is coaxially connected to the front end of the rotor of the second motor 15. An atomizing nozzle 6 is installed in the rear of the inner cavity of the treatment box 2. The outlet of the water pump 9 is connected to the interior of the atomizing nozzle 6. The first motor 14 drives the rotating shaft 5 to rotate, thereby causing the square paddle 7 and the round paddle 8 to rotate. At the same time, the second motor 15 drives the cam 16 to rotate, which in turn drives the first motor 14 through the mounting plate 13. The rotating shaft 5 moves up and down synchronously, causing the square and round paddles 7 and 8 to rotate in unison. This creates strong turbulence within the treatment chamber, ensuring thorough contact between the flue gas and the denitrification agent, improving mixing uniformity, and promoting the denitrification reaction. Furthermore, the movement of the square and round paddles 7 and 8 allows for complete mixing of the flue gas and denitrification agent in three-dimensional space, increasing the contact area, improving reaction efficiency, and enhancing the overall quality of the carbon reduction device. This ensures that the emitted flue gas is adequately purified. Please refer to [link / reference]. Figure 1A water inlet pipe 19 is installed on the top of water tank 4, and a smoke exhaust pipe 18 is installed on the lower left side of treatment tank 2. Please refer to [link / reference]. Figure 2 There are 2-4 sets of both square paddles 7 and round paddles 8. The planes of both square paddles 7 and round paddles 8 are perpendicular to each other. Please refer to [link / reference]. Figure 4 The rotor front end of the second motor 15 passes through the corresponding position of the connecting frame 11. The front end of the cam 16 is connected to the corresponding position on the inner side of the connecting frame 11 via a bearing. The length of the cam 16 is the same as the width of the mounting plate 13. Please refer to [link / reference]. Figure 5 Springs 17 are fitted on the outside of the assembly rod 12 at the position between the top of the processing box 2 and the bottom of the mounting plate 13. The upper and lower ends of the springs 17 are connected to the corresponding positions of the top of the processing box 2 and the bottom of the mounting plate 13, respectively.
[0034] This design uses a first motor 14 to drive the rotation of the rotating shaft 5, which in turn causes the square lever 7 and the circular lever 8 to rotate. Simultaneously, a second motor 15 drives the rotation of the cam 16, which in turn causes the first motor 14 and the rotating shaft 5 to move up and down via the mounting plate 13. This synchronized up-and-down movement of the square lever 7 and the circular lever 8 creates strong turbulence within the treatment chamber, ensuring thorough contact between the flue gas and the denitrification agent, improving mixing uniformity, and promoting the denitrification reaction. Furthermore, the movement of the square lever 7 and the circular lever 8 allows for thorough mixing of the flue gas and the denitrification agent in three-dimensional space, increasing the contact area, improving reaction efficiency, and enhancing the quality of the carbon reduction device, resulting in fully purified exhaust gas.
