Description

Technical Field

[0001] This utility model relates to the field of chimney purification technology, specifically to an environmentally friendly chimney purification device. Background Technology

[0002] A chimney is a structure that provides ventilation for hot flue gas or smoke from a boiler, furnace, stove, or fireplace. Chimneys are typically vertical, or as close to vertical as possible, to ensure a smooth flow of gas. The intake of air into the so-called chimney combustion, or chimney effect, is the space inside the chimney, which is called the flue. Chimneys can be found in buildings, steam locomotives, and ships. The height of a chimney affects its ability to deliver flue gas to the external environment through the chimney effect. Furthermore, the use of chimneys at high altitudes can reduce the impact on the surrounding environment by dispersing pollutants. In the case of chemically corrosive emissions, a sufficiently tall chimney can allow chemicals in the air to partially or completely self-neutralize before reaching the ground level. The dispersion of pollutants over a larger area can reduce their concentration and promote compliance with regulatory limits.

[0003] A search revealed a spray-type flue gas purification and environmentally friendly chimney disclosed in Chinese utility model patent publication number "CN217843909U". The chimney includes a chimney body, a spray box at the top of the chimney body, a cleaning device fixedly installed on the right side of the chimney body, a sterilizing lamp fixedly installed inside the spray box, a water-blocking block fixedly installed at the top of the chimney body, and a water outlet pipe plate fixedly installed at the top of the spray box. This spray-type flue gas purification and environmentally friendly chimney, by incorporating a sterilizing lamp, can sterilize harmful substances in the emitted flue gas, thereby enhancing the environmental protection treatment of the flue gas. Simultaneously, the water-blocking block fixedly installed at the top of the chimney body prevents water from entering the interior of the chimney body and causing danger. Furthermore, a waterproof sleeve is installed on the outer surface of the chimney body to prevent water ingress, allowing the chimney body to operate normally, thus reducing the harm to the environment caused by direct flue gas discharge and protecting the environment.

[0004] The current device relies solely on spraying and simple filtration, which is insufficient for removing pollutants that are difficult to dissolve in water, such as nitrogen oxides and heavy metals. This makes it difficult to meet the needs of diverse pollution control. Therefore, an environmentally friendly chimney purification device is proposed to solve the above problems. Summary of the Invention

The surface of the collection frame is fixedly installed with a sealing gasket, which is in contact with the inner wall of the mounting groove. One end of the collection frame is magnetically connected to the mounting groove.

[0010] Preferably, the baffle plate and the intake pipe are designed on the same horizontal plane and are close to one end of the intake pipe.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0022] Please see Figure 1-5 An environmentally friendly chimney purification device in this embodiment includes a purification device 1, a chimney body 2 is bolted to the top of the purification device 1, and an air inlet pipe 3 is fixedly installed on one side of the purification device 1.

[0023] The purification device 1 includes a purification box 11 installed at the bottom of the chimney body 2. The purification box 11 has an installation groove 12, a pretreatment groove 13 and a purification groove 14 inside. The top surface of the purification box 11 and the bottom of the chimney body 2 has a smoke exhaust port 15. A collection frame 16 is slidably installed inside the installation groove 12. Three return springs 17 are fixedly installed on the inner wall of the pretreatment groove 13. A rotating shaft 18 is rotatably installed inside the pretreatment groove 13. A baffle 19 is fixedly installed on the surface of the rotating shaft 18. A storage box 20 is fixedly installed on the outside of the purification box 11. A delivery pump 21 is fixedly installed on the top of the storage box 20. An atomizer 22 is fixedly installed on the front inner wall of the purification groove 14. A bracket 23 is fixedly installed inside the purification groove 14. A pipe 24 is fixedly installed inside the bracket 23. Five atomizing nozzles 25 are fixedly installed on the surface of the bracket 23. An electrode plate 26 and an activated carbon adsorption plate 27 are installed from bottom to top inside the smoke exhaust port 15 by bolts.

[0024] In this embodiment, the flue gas containing pollutants enters the purification chamber 11 through the air inlet pipe 3 and undergoes the following treatment steps in sequence:

[0025] Preliminary separation in pretreatment tank 13: Flue gas first enters pretreatment tank 13 and impacts the baffle plate 19 mounted on the rotating shaft 18. The inertial force separates larger particulate pollutants such as coal ash and gravel from the flue gas, which fall into the mounting tank 12 below and are collected in the sliding collection frame 16. The baffle plate 19 can rotate under the impact of flue gas. With the elastic action of the return spring 17, the collision and separation effect of particulate matter is enhanced, while avoiding excessive flue gas resistance.

[0026] Purification tank 14 spraying and chemical absorption: The purification liquid, such as alkaline absorbent, in the storage tank 20 is pressurized by the delivery pump 21 and transported through the pipeline 24 to the atomizer 22 and five atomizing nozzles 25 in the purification tank 14 to form fine droplets. The droplets are fully mixed with the flue gas and absorb the acidic gases (such as SO2 and HCl) in it, and a chemical reaction occurs to achieve purification processes such as desulfurization and deacidification.

[0027] Deep purification at the exhaust port 15: When the flue gas treated by spraying passes through the exhaust port 15, it first undergoes electrostatic dust removal through the electrode plate 26 to capture fine particulate matter (such as PM2.5); then it passes through the activated carbon adsorption plate 27 to adsorb residual heavy metals, volatile organic compounds (VOCs) and other harmful substances, and finally the qualified flue gas enters the chimney body 2 for emission.

[0028] In this embodiment, a multi-stage treatment process is employed, involving physical separation of large particulate pollutants in the pretreatment tank 13, absorption of acidic gases via atomized spraying in the purification tank 14, and deep purification of particulate matter and organic pollutants via the electrode plate 26 and activated carbon adsorption plate 27 at the exhaust port 15. This process efficiently covers both solid and gaseous multi-element pollutants in the flue gas, improving purification efficiency. Structurally, the collection frame 16 is slidably installed for easy slag removal, the combination of the baffle plate 19 and the return spring 17 reduces clogging, and the multi-layer arrangement of the atomizer 22 and the atomizing nozzle 25 enhances gas-liquid contact, achieving a compact design and convenient maintenance. In terms of resource utilization, the storage box 20 is adapted to customized absorbents, and electrostatic dust removal and activated carbon adsorption support the recovery of metal particles and the regeneration of activated carbon, reducing costs and pollutant emissions, meeting environmental standards, and suitable for various scenarios such as industrial boilers and waste incineration.

[0029] Compared with traditional spraying methods, this method achieves better purification results, higher treatment efficiency, resource recycling to reduce costs, and is more in line with environmental protection standards.

[0030] The purification box 11 has sliding grooves on both the left and right sides of the mounting groove 12, and the collection frame 16 has sliding strips fixedly installed on both sides that are slidably connected to the sliding grooves. The surface of the collection frame 16 is fixedly installed with a sealing gasket, and the sealing gasket is in contact with the inner wall of the mounting groove 12. One end of the collection frame 16 is magnetically connected to the mounting groove 12.

[0031] In this embodiment, the purified impurities fall into the collection frame 16 for collection and processing. The collection frame 16 is easily pulled out through the sliding connection of the slide groove and the slide bar, which facilitates regular cleaning of impurities. The sealing gasket fits snugly against the inner wall of the mounting groove 12 to prevent flue gas leakage and ensure the airtightness of the purification system. The magnetic connection ensures that the collection frame 16 is installed firmly, avoiding displacement due to vibration, and at the same time facilitates quick disassembly and maintenance, improving the convenience of operation and the reliability of system operation.

[0032] In summary, this environmentally friendly chimney purification device physically separates large particulate pollutants through the pretreatment tank 13, absorbs acidic gases through atomized spraying in the purification tank 14, and deeply purifies particulate matter and organic pollutants through the electrode plate 26 and activated carbon adsorption plate 27 at the exhaust port 15, covering solid and gaseous multi-element pollutants. Compared with traditional spraying methods, it has a better purification effect and higher treatment efficiency. The collection frame 16 is conveniently pulled out through the sliding connection of the sliding groove and the sliding strip. With the sealing gasket to prevent leakage and the magnetic connection to ensure stable installation, it is easy to clean impurities and prevent flue gas leakage, while improving the convenience of disassembly and maintenance and the reliability of system operation.
