DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0021] REFERENCE Figures 1-9A flue gas purification device for desulfurization and denitrification includes a support component 1. The support component 1 includes a housing 101. A controller 4 and a control panel are fixed to one outer wall of the housing 101 by bolts. The control panel is electrically connected to the controller 4. The controller 4 is model DATA-7311. The housing 101 has openings 102 on multiple sides. Smoke guide hoods 103 are bolted between the inner walls of the housing 101 to guide the flue gas upwards. A top cover 104 is bolted to the top of the housing 101 to seal the top and prevent external debris from entering or internal flue gas from leaking. A bottom plate 105 is bolted to the bottom of the housing 101 to seal the top and prevent external debris from entering or internal flue gas from leaking. Both the inlet and outlet of the housing 101 are connected to ultrasonic flue gas flow meters 106 via flanges. The flow data of flue gas is monitored in real time and transmitted to the controller 4 for processing to ensure that the purification effect matches the flow. The flue gas ultrasonic flow meter 106 is model XBO. One end of the flue gas ultrasonic flow meter 106 is connected to the inlet pipe 107 through a flange, which is used to introduce the boiler flue gas to be purified into the housing 101. The other end of the flue gas ultrasonic flow meter 106 is connected to the outlet pipe 108 through a flange, which is used to discharge the purified flue gas out of the housing 101 and to the designated area. The bottom of the housing 101 is fixed with a bracket 109 by bolts. The housing 101 contains multiple sets of purification components 2. Each purification component 2 includes a slider 201, which is slidably connected between the inner walls of both sides of the housing 101. The slider 201 can slide out through the opening 102. A flue gas vent 202 is provided between the top and bottom of the slider 201. A filter plate 203 and an adsorption plate 204 are engaged in the flue gas vent 202. The flue gas passes through the filter plate 203 and the adsorption plate 204 to remove dust, as well as to achieve desulfurization and denitrification, thus purifying the flue gas. The filter plate 203 has a filtration mesh size of 100-200 mesh. The adsorption plate 204 uses high-temperature resistant ceramic fiber as a matrix and is loaded with a wide-temperature denitrification catalyst on its surface, simultaneously achieving dust removal, desulfurization, and denitrification for flue gas purification. One end of the slider 201 is fixed with a limit plate 20 by bolts. 5. This prevents the slider 201 from disengaging from the opening 102. A sealing gasket 206 is adhered to one side of the limiting plate 205. The sealing gasket 206 enhances the sealing between the slider 201 and the housing 101, preventing flue gas from leaking from the gap between the slider 201 and the housing 101. The sealing gasket 206 contacts one side of the outer wall of the housing 101. A sealing shell 207 is fitted onto the outer wall of the slider 201. Multiple fixing seats 208 are fixed to the outer wall of the housing 101 by bolts. Two electric push rods 209 are fixed to the top of the fixing seats 208 by bolts. One end of the electric push rod 209 is fixedly connected to the limiting plate 205. Under the contraction of the electric push rod 209, the fixing seat 208 is moved, thereby sliding the purification component 2 into the housing 101 from the opening 102 for the purification of flue gas. A protective component 3 is provided on the outer side of the opening 102. The protective component 3 includes a protective shell 301, which is fixed to the outer wall of the shell 101 by bolts. A transparent cover 302 is connected to one side of the protective shell 301 by a hinge. A locking block 303 is integrally formed on the outer wall of one side of the transparent cover 302. Two threaded rods 304 are rotatably connected to the outer wall of one side of the protective shell 301. The other end of the threaded rod 304 is engaged with the locking groove of the locking block 303. A locking nut 30 is threadedly connected to this end of the threaded rod 304. 5. Move the threaded rod 304 to separate it from the slot of the locking block 303. Then, open the transparent cover 302 to clean and replace the filter plate 203 and the adsorption plate 204. A sealing strip 306 is attached to one end of the transparent cover 302 to enhance the sealing between the transparent cover 302 and the protective shell 301 and prevent external air or debris from entering the shell 101 through the gaps and affecting the purification effect. A limiting block 307 is attached to one side of the outer wall of the transparent cover 302. The limiting block 307 can contact the limiting plate 205. Multiple connecting plates 5 are welded between adjacent protective shells 301 to enhance the connection strength between multiple protective shells 301, so that the protective components 3 form a whole and improve the structural stability of the device. The controller 4 is electrically connected to the flue gas ultrasonic flow meter 106 and the electric push rod 209. Each electric push rod 209 is equipped with an encoder to provide feedback on the travel trajectory of the slider 201.

[0022] The working principle of this embodiment is as follows: In use, the inlet pipe 107 and the outlet pipe 108 are connected to the boiler flue gas outlet and exhaust port. Then, the controller 4 starts a set of purification components 2. Under the contraction of the electric push rod 209, the fixed base 208 is moved, so that the purification components 2 slide into the housing 101 through the port 102. Then, the flue gas enters the housing 101 from the inlet pipe 107. Then, the flue gas is guided upward by the smoke guide hood 103 and then passes through the filter plate 203 and the adsorption plate 204 in sequence to remove dust in the flue gas, as well as desulfurization and denitrification, so as to achieve flue gas purification. The purified flue gas is discharged through the outlet pipe 108. During the purification process, the inlet and outlet flow rates are monitored by two ultrasonic flow meters 106. When the flow rate in the outlet pipe 108 decreases, it indicates that the filter plate 203 and adsorption plate 204 are saturated with ash and adsorption. The information is transmitted to the controller 4 for processing. Then, the controller 4 controls the electric push rod 209 to extend, thereby driving the used purification component 2 to slide from the port 102 into the corresponding protective shell 301. At the same time, the controller 4 controls another set of purification components 2 to start, and slides this set of purification components 2 into the shell 101 through the electric push rod 209 to continue purification. Then, unscrew the locking nut 305, and then turn the threaded rod 304 to separate it from the slot of the locking block 303. Then, open the transparent cover 302, and clean and replace the filter plate 203 and the adsorption plate 204. After cleaning and replacing, close the transparent cover 302 and the protective shell 301, and then turn the threaded rod 304 to engage with the slot of the locking block 303. Finally, tighten the locking nut 305 to lock it in place.
