[0002] With the development of industry, flue gas emitted by industries such as coal-fired power plants, iron and steel smelting, and chemical engineering contains a large amount of sulfur oxides and nitrogen oxides, seriously polluting the atmospheric environment. Due to its excellent adsorption performance and catalytic activity, activated carbon is widely used in the field of flue gas purification. In the prior art, the integrated desulfurization and denitrification equipment with activated carbon realizes the synergistic removal of pollutants through adsorption, catalytic reduction and other effects. However, it still faces challenges such as insufficient denitrification efficiency, easy inactivation of activated carbon, and difficult regeneration. Therefore, it is urgent to optimize the internal structure of the equipment, improve the utilization rate of activated carbon, and develop an efficient and low-consumption integrated desulfurization and denitrification technology.

The patent includes a reactor main body, with an inlet channel and an outlet channel respectively arranged at both ends. Inside the reactor main body, there are multiple activated carbon adsorption layers. On the reactor main body, there is a denitrification channel formed by connecting a flue gas channel, the cavity of the reactor main body, and a purified flue gas channel; a desulfurization channel formed by connecting a regeneration flue gas channel, the cavity of the reactor main body, and a sulfur-rich flue gas channel; a cooling channel formed by connecting a steam channel, the cavity of the reactor main body, and a steam discharge channel. The structure of the reactor main body is simple, and the denitrification reaction can be completed at low temperature without the need for additional low-temperature catalysts, reducing the equipment and catalyst costs. The denitrification process is simple, the flow inside the reactor main body is close to plug flow, no backmixing phenomenon will occur, the denitrification efficiency is high, the activated carbon adsorption layers are fixedly arranged, no additional power needs to be provided, the energy loss is small, and it will not cause pollution to the environment. Although this patent solves the above problems, there are still problems such as low denitrification efficiency and difficulty in quickly desulfurizing and denitrifying a large amount of flue gas generated in industrial production despite the simple operation. Therefore, a desulfurization and denitrification flue gas purification device with activated carbon arranged inside is proposed to solve the above-mentioned problems. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a desulfurization and denitrification flue gas purification device with activated carbon arranged inside in view of the deficiencies in the above-mentioned prior art.

[0005] To solve the above technical problems, the technical solution adopted by the present invention is as follows: A flue gas desulfurization and denitrification purification device with activated carbon inside, comprising a purification box.

The front end circumferential surface of the microporous tube is fixedly connected with a pulley. The drive shaft is rotatably connected with the inner surface of the purification box. The right end of the drive shaft is fixedly connected with a motor, and the motor is fixedly connected with the right side surface of the mounting frame. The right end of the reciprocating lead screw is rotatably connected with the inner surface of the exhaust port. The reciprocating lead screw is rotatably connected with the inner surface of the support plate. The left end of the guide rod is fixedly connected with the right side surface of the support plate. The moving frame is slidably connected with the circumferential surface of the guide rod through a slider. The pulley abuts against the upper and lower sides of the guide rail. The rear end circumferential surface of the microporous tube is rotatably connected with the inner surface of the infusion hose. The circumferential surface of the sponge roller abuts against the surface of the activated carbon cabinet. The surface of the infusion hose abuts against the circumferential surface of the support roller frame. The right end of the infusion hose penetrates through the rear side surface of the purification box. Insert the activated carbon cabinet into the purification box, and then the flue gas enters the purification box from the smoke inlet. At this time, the activated carbon in the activated carbon cabinet performs desulfurization and denitrification on the flue gas. Start the motor, the motor drives the drive shaft to rotate, the drive shaft drives the reciprocating lead screw to rotate, the reciprocating lead screw drives the moving frame to reciprocate on the guide rod, and the reciprocating movement of the moving frame is limited between the limit ring and the support plate. The moving frame drives the side connecting plate to move, the side connecting plate drives the microporous tube and the sponge roller to move left and right reciprocally. The catalyst is input into the microporous tube through the infusion hose. When the catalyst continuously flows into the microporous tube, the pressure inside the microporous tube gradually increases, so that the catalyst inside it is extruded through the micropores and absorbed by the sponge roller. The sponge roller absorbing the catalyst contacts the surface of the activated carbon in the activated carbon cabinet and is extruded to extrude the catalyst. During the reciprocating movement of the sponge roller, the catalyst can be evenly applied to the activated carbon. When the side connecting plate moves left and right reciprocally, it drives the infusion hose to move. The infusion hose is coiled around the support roller frame. When one end of the infusion hose is pulled and moves,The supporting roller frame rotates and elongates the infusion hose. When the infusion hose resets, the supporting roller frame traction the infusion hose to make it rewind.

The pulley drives the microporous tube to rotate within the side connecting plate, and the microporous tube drives the sponge roller to rotate.

[0006] Preferably, the soot filter plate includes a chute support frame. The inner surface of the chute support frame is rotatably connected with a sliding ring. The inner surface of the soot filter plate is fixedly connected with a keyway sleeve shaft. The soot filter plate further includes a transmission shaft. The left side surface of the soot filter plate abuts against a friction roller. The circumferential surface of the reciprocating lead screw is fixedly connected with an adjusting plate. The left side surface of the adjusting plate is fixedly connected with a first elastic telescopic rod. The chute support frame is slidably connected with the inner wall of the purification box. The transmission shaft is slidably connected with the inner surface of the reciprocating lead screw through a spline. The circumferential surface of the soot filter plate is fixedly connected with the inner surface of the sliding ring. The transmission shaft is clamped with the inner surface of the keyway sleeve shaft through a spline. The right side surface of the adjusting plate abuts against the left side surface of the support plate. The left end of the first elastic telescopic rod is fixedly connected with the right side surface of the transmission shaft. After the flue gas enters the smoke inlet, it flows to the right and passes through the left side of the soot filter plate. After the flue gas passes through the soot filter plate, the large-particle impurities inside it are filtered by the soot filter plate. Insert the chute support frame into the purification box, and the chute support frame drives the sliding ring and the soot filter plate to be inserted into the purification box. On the contrary, when the chute support frame is pulled out of the purification box, the chute support frame drives the sliding ring and the soot filter plate to be pulled out of the purification box. The reciprocating lead screw rotates to drive the transmission shaft to rotate. The transmission shaft drives the keyway sleeve shaft to rotate. The keyway sleeve shaft drives the soot filter plate and the sliding ring to rotate within the chute support frame. When the soot filter plate rotates, it frictionally contacts the front friction roller. The friction roller sweeps off the dust adhering in the mesh holes of the soot filter plate through the action of friction. Pull the activated carbon cabinet out of the purification box. At this time, the staff can push the transmission shaft to move to the right to separate the transmission shaft from the keyway sleeve shaft. At this time, the chute support frame can be pulled out of the purification box. On the contrary, after the chute support frame is inserted into the purification box, the elastic reset action of the first elastic telescopic rod pushes the transmission shaft to the left and inserts it into the keyway sleeve shaft, enabling the reciprocating lead screw to drive the soot filter plate to rotate.

[0007] The L-shaped plate is fixedly connected to the rear surface of the L-shaped plate, and the L-shaped plate is fixedly connected to the rear surface of the L-shaped plate. The dust is quickly cleaned out of the purification box. When the smoke filter plate rotates, it drives the rotating push plate to rotate along the axis of the reciprocating screw. After the rotating push plate contacts the friction roller, it pushes it to rotate a certain angle. The friction roller then drives the torsion rod to rotate along the intersection with the L-shaped bracket. When the rotating push plate moves away from the friction roller, the elastic reset action of the torsion spring drives the torsion rod to rotate and reset, and the torsion rod drives the friction roller to reset again. The elasticity of the torsion spring causes the torsion rod and the friction roller to vibrate when they reset, thereby shaking off the dust adhered to the friction roller. The rotating push plate drives the extension plate to rotate in a circle. When the rotating push plate pushes the friction roller, the extension plate pushes the resistance plate to move from back to front, and the resistance plate drives the L-shaped baffle to slide forward and retract into the L-shaped through groove. When the extension plate moves away from the resistance plate, the elastic reset action of the elastic telescopic rod 2 pulls the L-shaped baffle to slide backward and reset, and blocks the notch of the L-shaped through groove to close the purification box.

[0008] The present invention adopts the above technical solution to bring the following beneficial effects: 1. The desulfurization and denitrification flue gas purification equipment is equipped with activated carbon. The activated carbon in the activated carbon cabinet desulfurizes and denitrifies the flue gas, thereby purifying the flue gas. The catalyst can be evenly applied to the activated carbon during the reciprocating movement of the sponge roller, thereby promoting the catalytic efficiency of the activated carbon and improving its adsorption effect. The microporous tube drives the sponge roller to rotate, which improves the contact efficiency between the sponge roller surface and the activated carbon, thereby making the catalyst more fully applied, further improving the adsorption efficiency of the activated carbon, and making the flue gas purification more efficient.

[0009] 2. The desulfurization and denitrification flue gas purification equipment is equipped with activated carbon. After the flue gas passes through the smoke filter plate, the large particles of impurities inside are filtered by the smoke filter plate to prevent the large particles from clogging the activated carbon. The slide support frame drives the sliding ring and the smoke filter plate to insert into the purification box. Conversely, the slide support frame is pulled out of the purification box, and the slide support frame drives the sliding ring and the smoke filter plate to be pulled out of the purification box, making the installation and disassembly of the device more convenient.

[0010] 3. For the flue gas desulfurization and denitrification purification equipment with activated carbon inside, when the dust filter plate rotates, it makes frictional contact with the friction roller on the front side. The friction roller sweeps off the dust adhering in the pores of the dust filter plate through the action of friction, preventing the dust filter plate from being blocked, making the flue gas flow more smoothly, and thus improving the flue gas purification efficiency. The elastic reset action of the first elastic telescopic rod pushes the transmission shaft to the left and inserts it into the keyway sleeve shaft, enabling the reciprocating lead screw to drive the dust filter plate to rotate, further improving the installation and disassembly efficiency.

[0011] 4. For the flue gas desulfurization and denitrification purification equipment with activated carbon inside, opening the L-shaped baffle can quickly remove the dust from the purification box, improving the cleaning efficiency of the device and facilitating the long-term flue gas filtration of the device. The elasticity of the torsion spring causes vibration when the torsion rod and the friction roller reset, thereby shaking off the dust adhering inside the friction roller and improving the dust concentration efficiency, further facilitating the subsequent treatment of the dust.

[0012] 5. For the flue gas desulfurization and denitrification purification equipment with activated carbon inside, the contact plate drives the L-shaped baffle to slide forward and retract into the L-shaped through groove, thereby quickly discharging the dust from the device. When the extension plate moves away from the contact plate, the elastic reset action of the second elastic telescopic rod pulls the L-shaped baffle to slide backward and reset, blocking the notch of the L-shaped through groove and closing the purification box.
