Description

Technical Field

[0001] This utility model relates to the field of waste heat boiler technology, and in particular to an environmentally friendly waste heat boiler. Background Technology

[0002] Environmentally friendly waste heat boilers are highly efficient and environmentally friendly heat recovery devices, primarily used to recover waste heat generated during industrial production. Through efficient flue gas treatment and energy conversion, they reduce energy waste and environmental pollution. These boilers are designed with energy conservation and emission reduction in mind, and are typically equipped with advanced flue gas purification systems, such as dust removal, desulfurization, and denitrification facilities, to ensure that emissions meet or exceed national environmental standards.

[0003] In existing technology, when the device is in use, high-temperature flue gas enters the waste heat boiler and flows through the boiler's heat exchange tube bundles. These tube bundles typically contain water or saturated steam. Since the flue gas temperature is much higher than the water temperature, heat is transferred from the flue gas to the heat exchange medium, causing the water to rapidly heat up to a boiling state and generate steam. The resulting steam enters the steam drum, where steam-water separation occurs. The steam rises, while the water sinks and continues to be heated. High-quality steam can be further heated to the required operating temperature through the superheater to meet process or power generation needs. Because the flue gas contains dust and particles, dust continuously adheres to and accumulates on the filter plates, causing filter plate blockage and significantly reducing dust removal efficiency. A large amount of dust may be discharged with the flue gas, polluting the environment. As dust increases on the filter plates, the effective filtration area of ​​the filter plates decreases, and the resistance of airflow through the filter plates increases, thereby reducing filtration efficiency and preventing the flue gas in the boiler from being fully purified. Therefore, it is necessary to improve the waste heat boiler to solve the above problems. Utility Model Content

[0004] To overcome the problem that in environmentally friendly waste heat boilers, dust and particles in the flue gas cause dust to continuously adhere to and accumulate on the filter plates, leading to filter plate blockage, significantly reducing dust removal efficiency, and potentially causing a large amount of dust to be discharged with the flue gas, polluting the environment, as the amount of dust on the filter plates increases, the effective filtration area of ​​the filter plates decreases, and the resistance of airflow through the filter plates increases, thereby reducing filtration efficiency and preventing the flue gas in the boiler from being fully purified.

[0005] The technical solution of this utility model is as follows: an environmentally friendly waste heat boiler, including a waste heat boiler body, a limiting fixing rod and a discharge assembly, a support base fixedly connected to the bottom of the waste heat boiler body, a flue gas outlet fixedly connected to the top of the waste heat boiler body, a flue gas inlet opened on the front of the waste heat boiler body, an equipment body inside the waste heat boiler body, a discharge assembly set inside the waste heat boiler body, a limiting fixing rod fixedly connected inside the waste heat boiler body, a second motor fixedly connected to the back of the equipment body, a first pulley fixedly connected to the output end of the second motor, a second pulley rotatably connected inside the equipment body, a connecting transmission belt externally connected to the second pulley, the connecting transmission belt rotatably connected to the outside of the first pulley, a rotating threaded rod fixedly connected to the front of the second pulley, a threaded support rod threadedly connected to the outside of the rotating threaded rod, a cleaning roller rotatably connected inside the threaded support rod, and an adsorption tank opened inside the equipment body.

[0006] Preferably, there are two rotating threaded rods, and the two rotating threaded rods are symmetrically connected inside the main body of the equipment.

[0007] Preferably, the main body of the equipment has a groove at the corresponding position of the threaded support rod, and the threaded support rod slides inside the groove.

[0008] Preferably, the main body of the equipment is equipped with an electric telescopic rod, and a pushing and pressing plate is fixedly connected to the bottom of the electric telescopic rod. The pushing and pressing plate is slidably connected inside the main body of the equipment, and a pushing block is fixedly connected to the bottom of the pushing and pressing plate.

[0009] Preferably, there are several push blocks, and the several push blocks are evenly and fixedly connected to the bottom of the corresponding push block in the adsorption groove.

[0010] Preferably, the discharge assembly includes a guide plate, which is fixedly connected inside the waste heat boiler body. The waste heat boiler body has a discharge port inside, and a fixed support plate is fixedly connected inside. A first motor is fixedly connected to the back of the fixed support plate, and a hydraulic telescopic rod is fixedly connected to the output end of the first motor. A push guide plate is fixedly connected to the front of the hydraulic telescopic rod, and a rotating connecting shaft is rotatably connected inside the push guide plate. A cleaning brush is fixedly connected to the outside of the rotating connecting shaft.

[0011] Preferably, the waste heat boiler body has a groove at the corresponding position of the push guide plate, and the push guide plate slides inside the groove.

[0012] Preferably, the guide plate has a groove at the corresponding position of the sweeping brush, and the sweeping brush slides inside the groove.

[0013] The beneficial effects of this utility model are:

[0014] 1. Compared to environmentally friendly waste heat boilers that cannot clean dust on filter plates, this method, by rotating the threaded rod and threaded support rod in a threaded connection, causes the threaded support rod to slide inside the main body of the equipment under the limit of the limiting and fixing rod. The sliding of the threaded support rod drives the cleaning roller to rotate, cleaning the surface of the adsorption tank and causing the dust to fall to the bottom of the inner side of the waste heat boiler body. This prevents a large amount of dust from being discharged with the flue gas and polluting the environment. As the dust on the filter plate increases, the filtration effect of the flue gas is improved, and the resistance of airflow through the filter plate is reduced, so that the flue gas inside the device is fully purified. This effectively prevents the dust and particles in the flue gas of the waste heat boiler from continuously adhering and accumulating on the filter plate, causing the filter plate to become clogged and the dust removal effect to drop significantly.

[0015] 2. For environmentally friendly waste heat boilers where internal dust cannot be removed, a first motor drives a hydraulic telescopic rod to push a guide plate that slides inside the waste heat boiler body. The sliding and rotating connecting shaft of the guide plate drives a cleaning brush to rotate inside the guide plate, thus cleaning the dust particles inside the waste heat boiler body. This effectively cleans the dust inside the waste heat boiler body, preventing the accumulation of dust inside the device from affecting the flue gas treatment effect and ensuring the purification effect of the flue gas.

[0023] Please see Figure 1 - Figure 5This utility model provides an embodiment of an environmentally friendly waste heat boiler, including a waste heat boiler body 1, a limiting fixing rod 901, and a discharge assembly. A support base 2 is fixedly connected to the bottom of the waste heat boiler body 1, a flue gas outlet 3 is fixedly connected to the top of the waste heat boiler body 1, a flue gas inlet 4 is opened on the front of the waste heat boiler body 1, an equipment body 5 is arranged inside the waste heat boiler body 1, the discharge assembly is arranged inside the waste heat boiler body 1, the limiting fixing rod 901 is fixedly connected inside the waste heat boiler body 1, a second motor 902 is fixedly connected to the back of the equipment body 5, and the output end of the second motor 902 is fixedly connected to a... A first pulley 903 is rotatably connected to a second pulley 904 inside the main body 5 of the equipment. A connecting drive belt 905 is externally connected to the second pulley 904, and the connecting drive belt 905 is rotatably connected to the outside of the first pulley 903. A rotating threaded rod 906 is fixedly connected to the front of the second pulley 904, and a threaded support rod 907 is threadedly connected to the outside of the rotating threaded rod 906. A cleaning roller 908 is rotatably connected inside the threaded support rod 907. An adsorption tank 909 is provided inside the main body 5 of the equipment. The waste heat boiler body 1 is supported by a support base 2, and the exhaust gas enters through the flue gas inlet 4. Inside the waste heat boiler body 1, the filtered flue gas is discharged through the flue gas outlet 3. A second motor 902 drives a first pulley 903 to rotate inside the equipment body 5. The rotation of the first pulley 903, through the transmission belt 905, drives a second pulley 904 to rotate. The rotation of the first and second pulleys 903 and 904 drives two rotating threaded rods 906 to rotate. With the threaded rods 906 and threaded support rods 907 connected, the threaded support rods 907 slide within the equipment body 5 under the limitation of the limiting and fixing rod 901. The movement of the threaded support rod 907 drives the cleaning roller 908 to rotate, thus cleaning the surface of the adsorption tank 909. There are two rotating threaded rods 906, which are symmetrically connected inside the main body 5 of the equipment. The two rotating threaded rods 906 make the threaded support rod 907 more stable when sliding. The main body 5 has a groove at the corresponding position of the threaded support rod 907. The threaded support rod 907 slides inside the groove. The groove at the corresponding position of the threaded support rod 907 inside the main body 5 limits the sliding of the threaded support rod 907.

[0024] Please see Figure 4 - Figure 5In this embodiment, an electric telescopic rod 910 is provided inside the main body 5 of the device. A pushing and squeezing plate 911 is fixedly connected to the bottom of the electric telescopic rod 910. The pushing and squeezing plate 911 is slidably connected inside the main body 5 of the device. A pushing block 912 is fixedly connected to the bottom of the pushing and squeezing plate 911. The pushing and squeezing plate 911 is pushed to slide inside the main body 5 by the electric telescopic rod 910. The pushing and squeezing plate 911 pushes the pushing block 912 into the adsorption tank 909, squeezing out the dust and impurities inside the adsorption tank 909. Several pushing blocks 912 are provided, and several pushing blocks 912 are evenly fixedly connected to the bottom of the corresponding pushing blocks 912 in the adsorption tank 909. The multiple pushing blocks 912 make the cleaning of dust and impurities inside the adsorption tank 909 more uniform.

[0025] Please see Figure 2 - Figure 3 In this embodiment, the discharge assembly includes a guide plate 801. The guide plate 801 is fixedly connected inside the waste heat boiler body 1. The waste heat boiler body 1 has a discharge port 802. A fixed support plate 803 is fixedly connected inside the waste heat boiler body 1. A first motor 804 is fixedly connected to the back of the fixed support plate 803. A hydraulic telescopic rod 805 is fixedly connected to the output end of the first motor 804. A push guide plate 806 is fixedly connected to the front of the hydraulic telescopic rod 805. A rotating connecting shaft 807 is rotatably connected inside the push guide plate 806. A cleaning brush 808 is fixedly connected to the outside of the rotating connecting shaft 807. The guide plate 801 prevents heavier dust particles from entering and falling into the discharge port 802. The first motor 804 drives the hydraulic telescopic rod 805 to push the push guide plate 806. The guide plate 806 slides inside the waste heat boiler body 1. The sliding and rotating connecting shaft 807 of the guide plate 806 drives the cleaning brush 808 to rotate inside the guide plate 806, so that it cleans the dust particles inside the waste heat boiler body 1. The waste heat boiler body 1 has a groove at the corresponding position of the guide plate 806. The guide plate 806 slides inside the groove. The groove at the corresponding position of the guide plate 806 inside the waste heat boiler body 1 limits the guide plate 806 when it slides inside the groove. The guide plate 806 has a groove at the corresponding position of the cleaning brush 808. The cleaning brush 808 slides inside the groove. The groove at the corresponding position of the guide plate 806 makes the cleaning brush 808 clean the inside of the waste heat boiler body 1 more evenly.

[0026] During operation, when cleaning the dust inside the equipment, the electric telescopic rod 910 pushes the extrusion plate 911 to slide inside the equipment body 5. Pushing the extrusion plate 911 inserts the push block 912 into the adsorption tank 909, squeezing out the dust and impurities inside. The second motor 902 drives the first pulley 903 to rotate inside the equipment body 5. The rotation of the first pulley 903, connected to the transmission belt 905, drives the second pulley 904 to rotate. The rotation of the first and second pulleys 903 and 904 drives two rotating threaded rods 906 to rotate. With the rotating threaded rods 906 threadedly connected to the threaded support rods 907, they drive... The threaded support rod 907 slides inside the main body 5 of the equipment under the limitation of the limiting and fixing rod 901. The sliding of the threaded support rod 907 drives the cleaning roller 908 to rotate, so that it cleans the surface of the adsorption tank 909, and the dust falls into the bottom of the inner side of the waste heat boiler body 1. The guide plate 801 sets the guide plate to block the heavier dust particles from falling into the discharge port 802. The first motor 804 drives the hydraulic telescopic rod 805 to push the guide plate 806 to slide inside the waste heat boiler body 1. The sliding and rotating connecting shaft 807 of the guide plate 806 drives the cleaning brush 808 to rotate inside the guide plate 806, so that it cleans the dust particles inside the waste heat boiler body 1.

[0027] Through the above steps, the second motor 902 drives the first pulley 903 to rotate inside the equipment body 5. The rotation of the first pulley 903, coupled with the transmission belt 905, drives the second pulley 904 to rotate. The rotation of the first pulley 903 and the second pulley 904 drives the two rotating threaded rods 906 to rotate. With the threaded connection between the rotating threaded rods 906 and the threaded support rods 907, the threaded support rods 907 slide inside the equipment body 5 under the limitation of the limiting and fixing rod 901. The sliding motion of roller 7 drives the cleaning roller 908 to rotate, cleaning the surface of the adsorption tank 909 and causing the dust to fall into the bottom of the inner side of the waste heat boiler body 1. This solves the problem that in environmentally friendly waste heat boilers, dust and particles in the flue gas will continuously adhere to and accumulate on the filter plate, causing the filter plate to become clogged, resulting in a significant decrease in dust removal efficiency. A large amount of dust may be discharged with the flue gas, polluting the environment. As the dust on the filter plate increases, the effective filtration area of ​​the filter plate decreases, and the resistance of airflow through the filter plate increases, thereby reducing the filtration efficiency and preventing the flue gas in the boiler from being fully purified.
