Description

Technical Field

[0001] This utility model relates to the field of waste gas desulfurization and denitrification technology, and in particular to an energy-saving waste gas desulfurization and denitrification device. Background Technology

[0002] In industrial production, in order to reduce sulfur dioxide and nitrogen oxides in harmful gases during the production process and reduce air pollution, it is necessary to use an energy-saving waste gas desulfurization and denitrification equipment. This equipment can effectively reduce the emission of sulfur dioxide and nitrogen oxides, reduce air pollution, improve air quality, and thus protect the ecological environment.

[0003] A search revealed a Chinese patent publication number (CN221580185U) that discloses an energy-saving waste gas desulfurization and denitrification device. The device includes a housing and uses heat-conducting fins to absorb heat from the waste gas. A pump in the water storage tank is activated to extract hot water, which is then delivered to the heat exchanger via a delivery pipe. The heat-conducting fins transfer heat to the hot water, heating it and thus recovering and utilizing the heat from the flue gas. This also reduces the heat content of the flue gas, which is beneficial for subsequent desulfurization and denitrification treatment.

[0004] Considering that flue gas contains impurities such as dust, particulate matter, and corrosive gases, these substances will adhere to the surface of the heat-conducting fins, reducing the heat exchange efficiency of the fins and thus affecting the heat transfer effect, and may even damage the equipment. Therefore, an energy-saving waste gas desulfurization and denitrification equipment is proposed to solve the above problems. Summary of the Invention

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.

[0033] Reference Figure 1 , Figures 3-4 This utility model provides an embodiment of an energy-saving waste gas desulfurization and denitrification device, comprising a treatment chamber 1. A flue gas inlet pipe 3 is fixedly connected to the right side of the outer surface of the treatment chamber 1, allowing flue gas to enter the treatment chamber 1 through the inlet pipe 3. Heat-conducting fins 17 are fixedly connected to the inner surface of the inlet pipe 3, allowing the heat-conducting fins 17 to absorb heat from the flue gas inside the inlet pipe 3. A scraper 14 is slidably connected through and to the outer surface of the heat-conducting fins 17, allowing the scraper 14 to move vertically along the outer surface of the heat-conducting fins 17 to scrape away impurities. A column 21 is fixedly connected to the top of the outer surface of the scraper 14, allowing the column 21 to move vertically and drive the scraper 14 to move together. The surface of the column 21 is slidably connected to the top of the inner surface of the flue gas inlet pipe 3, allowing the column 21 to move vertically along the top of the inner surface of the flue gas inlet pipe 3. The top of the outer surface of the column 21 is fixedly connected to a plate 6, allowing the plate 6 to move the column 21 together when it moves vertically. The inner surface of the plate 6 is threadedly connected to a threaded rod 8, allowing the threaded rod 8 to move the plate 6 vertically when it rotates. The bottom of the outer surface of the threaded rod 8 is rotatably connected to the top of the inner surface of the flue gas inlet pipe 3, allowing the threaded rod 8 to rotate at a designated position at the top of the inner surface of the flue gas inlet pipe 3. The inner surface of the treatment chamber 1 is equipped with a desulfurization and denitrification assembly, enabling the treatment chamber 1 to perform desulfurization and denitrification treatment on the flue gas through the desulfurization and denitrification assembly.

[0034] Reference Figures 2-4The desulfurization and denitrification assembly includes a spray head 12, a filter plate 11, and a flue pipe 2. The outer surface of the spray head 12 is fixedly connected to the top of the inner surface of the treatment chamber 1, enabling the spray head 12 to spray the reaction liquid onto the flue gas inside the treatment chamber 1. The outer surface of the filter plate 11 is fixedly connected to the middle of the inner surface of the treatment chamber 1, enabling the filter plate 11 to filter the reaction liquid that has reacted with the flue gas. The top of the outer surface of the treatment chamber 1 is fixedly connected to the flue pipe 2, allowing the reacted flue gas to be discharged from the treatment chamber 1 through the flue pipe 2. A hinge rod 15 is hinged to the bottom of the outer surface of the scraper 14, allowing the scraper to... When the plate 14 moves vertically, it can drive the hinge rod 15 to move together. The bottom of the outer surface of the hinge rod 15 is hinged to a baffle 16, so that when the hinge rod 15 is driven by the scraper 14, it can drive the baffle 16 to move together. The right side of the outer surface of the baffle 16 is hinged to the bottom of the inner surface of the smoke inlet pipe 3, so that when the baffle 16 is driven by the hinge rod 15, it can flip along the bottom of the inner surface of the smoke inlet pipe 3. The bottom of the outer surface of the smoke inlet pipe 3 is fixedly connected to an ashtray 4, so that the impurities scraped off by the scraper 14 can fall into the ashtray 4 for unified recycling.

[0035] Reference Figure 1 , Figure 5A heat insulation shell 5 is fixedly connected to the top of the outer surface of the flue pipe 3, providing a fixed support for the heat insulation shell 5. A heat-conducting pipe 20 is fixedly connected to the inner surface of the heat insulation shell 5, providing a fixed support for the heat-conducting pipe 20. This allows the heat generated by the heat-conducting pipe 20 to affect the top component of the heat insulation shell 5 during heat conduction. The bottom of the outer surface of the heat-conducting pipe 20 contacts the top of the outer surface of the heat-conducting fin 17, allowing the heat-conducting fin 17 to transfer heat to the heat-conducting pipe 20 when absorbing heat from the flue gas. A water tank 7 is fixedly connected to the top of the outer surface of the flue pipe 3, providing a fixed support for the water tank 7. A water inlet pipe 10 is fixedly connected to the front of the outer surface of the top of the water tank 7, allowing unheated water to be introduced into the water tank 7. An overflow pipe 19 is fixedly connected to the rear of the outer surface of the water tank 7, allowing the water tank to overflow. The heated water inside the water tank 7 can overflow out of the water tank 7 through the overflow pipe 19. The outer left side of the heat conduction pipe 20 penetrates and is fixedly connected to the inner surface of the water tank 7, so that the heat conduction pipe 20 can transfer heat to the inside of the water tank 7 to heat the water inside the water tank 7. The front end of the outer left side of the flue pipe 3 is fixedly connected to the water pump 9, which is fixedly supported by the front end of the outer left side of the flue pipe 3. The top end of the outer surface of the water pump 9 is fixedly connected to the bottom end of the outer surface of the water inlet pipe 10, so that the water pump 9 can pump unheated water into the water tank 7 through the water inlet pipe 10. The rear end of the outer surface of the flue pipe 3 is fixedly connected to the water storage tank 18, which is fixedly supported by the rear end of the outer surface of the flue pipe 3. The bottom end of the outer surface of the overflow pipe 19 is fixedly connected to the top end of the outer surface of the water storage tank 18, so that the water overflowing out of the water tank 7 can flow into the water storage tank 18 through the overflow pipe 19.

[0036] Reference Figure 6 A motor 13 is fixedly connected to the top of the outer surface of the heat insulation shell 5, providing a fixed support for the motor 13. A second bevel gear 23 is fixedly connected to the left side of the outer surface of the motor 13, enabling the motor 13 to drive the second bevel gear 23 to rotate. A first bevel gear 22 is fixedly connected to the bottom of the outer surface of the threaded rod 8, enabling the first bevel gear 22 to drive the threaded rod 8 to rotate simultaneously when it rotates. The bottom of the outer surface of the first bevel gear 22 meshes with the left side of the outer surface of the second bevel gear 23, so that when the motor 13 drives the second bevel gear 23 to rotate, the threaded rod 8 can rotate simultaneously due to the meshing of the second bevel gear 23 and the first bevel gear 22.

[0037] Working principle: When it is necessary to clean the heat-conducting fins 17, the motor 13 is started, which drives the threaded rod 8 to rotate due to the meshing of two sets of bevel gears. This causes the plate 6 to move downward by the threaded rod 8, and at the same time, it drives multiple sets of columns 21 to move downward vertically. The columns 21 drive the scraper 14 to scrape the heat-conducting fins 17 from top to bottom. When the scraper 14 moves downward, it will drive the hinge rod 15 to move downward as well. The baffle 16 will flip downward along the bottom of the inner surface of the smoke inlet pipe 3 due to its hinge with the hinge rod 15, so that the impurities scraped off by the scraper 14 fall into the ashtray 4. This achieves the effect of scraping and cleaning the impurities on the surface of the heat-conducting fins 17 and collecting them.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
