Description

Technical Field

[0001] This invention relates to the field of flue gas purification technology, and more specifically, to an intelligent asphalt flue gas purification device and method utilizing activated carbon adsorption. Background Technology

[0002] The composition of asphalt fume mainly consists of a large number of long-chain cycloalkanes and alkylbenzene compounds, as well as small amounts of single-chain alkanes and complex organic compounds such as alcohols and esters. The fume must be purified before it can be emitted. Existing technologies employ dust suppression spraying, oil-water separation, photo-oxidation, plasma, electrostatic capture, and activated carbon to filter the fume. Intelligent control is achieved by using sensors to detect the composition of the emitted fume. However, during activated carbon filtration, due to the limited contact area between the fume and the activated carbon, some activated carbon may not have fully participated in the purification process after its service life, reducing the utilization rate of the activated carbon. Summary of the Invention

An isolation ring is fixedly installed in the inner cavity of the first fixed tube, and activated carbon is inserted into the inner cavity of the isolation ring. The drive assembly includes a motor, a nozzle is rotatably connected to the middle of the fixed tube two, and a transmission wheel is fixedly sleeved on both the output end of the motor and the rear end of the nozzle. A transmission belt is connected to the surface of the transmission wheel. The connecting assembly includes a connecting pipe, which is fixedly installed at the right end of the second fixed pipe. A connecting ring is fixedly installed at the left end of the connecting pipe. Positioning rings are fixedly installed at both the front and rear ends of the inner cavity of the connecting ring. A support ring is rotatably connected to the rear end of the outer shell.

[0005] As a preferred embodiment of the present invention, the pipe assembly includes an inlet pipe and an outlet pipe, wherein the inlet pipe is fixedly installed at the right end of the housing and the outlet pipe is fixedly installed at the left end of the housing.

[0006] As a preferred embodiment of the present invention, a discharge assembly is fixedly installed on the left end of the housing. The discharge assembly includes an induced draft fan, which is located on the left side of the housing and connected to the exhaust pipe. The output end of the induced draft fan is fixedly sleeved with an exhaust pipe.

[0007] As a preferred embodiment of the present invention, a sensor is fixedly installed at the bottom end of the discharge pipe.

[0008] As a preferred embodiment of the present invention, a limiting ring is fixedly installed at the front end of the second fixed tube, and the inner diameter of the limiting ring is smaller than the diameter of the activated carbon.

[0009] As a preferred embodiment of the present invention, the left end of the isolation ring is provided with an opening, the depth of the opening is the same as the length of the isolation ring, and the projection of the fixed position of the air outlet pipe and the fixed pipe in the vertical direction is located inside the opening.

[0010] As a preferred embodiment of the present invention, the two positioning rings are respectively inserted into the inner cavities of the support ring and the nozzle, and the connecting pipe is connected to the air intake pipe.

[0011] As a preferred embodiment of the present invention, an ejection assembly is fixedly installed at the left end of the inner cavity of the fixed tube II. The ejection assembly includes a positioning frame, a gear is rotatably connected to the middle of the positioning frame, a lead screw is meshed in the inner cavity of the gear, a rack is fixedly installed at the rear end of the nozzle, and a maintenance door is hinged to the front end of the outer shell.

[0012] As a preferred embodiment of the present invention, the rack meshes with the gear, the lead screw is located behind the activated carbon, and rectangular grooves are provided at both the upper and lower ends of the lead screw. A positioning strip is slidably connected in the rectangular groove, and the positioning strip is fixedly installed at the right end of the positioning frame.

[0013] A method of using an intelligent asphalt fume purification device utilizing activated carbon adsorption, the method comprising the following steps: The right end of the outer casing is connected to spray dust suppression, oil-water separation, photo-oxidation, plasma and electro-capture equipment, which are used to remove harmful substances in the flue gas generated during asphalt production. The treated flue gas enters the connecting component and then enters the drive component. During the purification process, the drive component evenly sprays the flue gas onto the rear end of the filter component to further adsorb and filter the residual harmful substances in the flue gas, and finally discharges the flue gas through the emission component. During the flue gas purification process, the drive component will drive the ejector component to push the activated carbon forward to the maintenance door. When the activated carbon needs to be replaced, open the maintenance door to replace the activated carbon. After the replacement is completed, the drive component reverses the drive to push out the component for reset.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The motor of the present invention drives the nozzle to rotate through the transmission wheel and transmission belt, thereby enabling the nozzle on the nozzle to rotate behind the activated carbon. This achieves uniform spraying of the flue gas entering the nozzle through the connecting pipe and connecting ring onto the surface of the activated carbon, ensuring uniform contact between the activated carbon and the flue gas, improving the flue gas purification efficiency, and avoiding the situation where some activated carbon does not fully participate in the flue gas purification, thus improving the utilization rate of activated carbon.

[0015] 2. This invention, by setting a rack, allows the spray nozzle to rotate and evenly spray the flue gas onto the activated carbon during the flue gas purification process. The rotation of the nozzle drives the rack to rotate, and each rotation of the rack drives the gear to rotate at a certain angle, which in turn drives the lead screw to extend forward a certain distance. When the activated carbon reaches its replacement cycle, the movement of the lead screw will push the activated carbon forward to contact the maintenance door. At this time, the maintenance door can be opened to directly remove and replace the activated carbon, making the operation simple and convenient. Attached Figure Description

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] like Figures 1 to 6 As shown, the present invention provides an intelligent asphalt fume purification device using activated carbon adsorption, including a shell 1, a pipe assembly 2 fixedly installed in the inner cavity of the shell 1, a filter assembly 4 fixedly installed in the middle of the inner cavity of the shell 1, a drive assembly 5 provided at the rear end of the filter assembly 4, and a connecting assembly 6 connected to the middle of the drive assembly 5. The filter assembly 4 includes a first fixing tube 41, which is fixedly installed at the front end of the inner cavity of the outer shell 1. A second fixing tube 42 is fixedly installed at the rear end of the first fixing tube 41. An isolation ring 44 is fixedly installed in the inner cavity of the first fixing tube 41, and activated carbon 45 is inserted into the inner cavity of the isolation ring 44. The drive assembly 5 includes a motor 51, a nozzle 53 is rotatably connected to the middle of the fixed tube 42, and a transmission wheel 52 is fixedly sleeved on both the output end of the motor 51 and the rear end of the nozzle 53. A transmission belt 54 is connected to the surface of the transmission wheel 52. The connecting component 6 includes a connecting pipe 61, which is fixedly installed at the right end of the fixed pipe 42. A connecting ring 62 is fixedly installed at the left end of the connecting pipe 61. Positioning rings 64 are fixedly installed at both the front and rear ends of the inner cavity of the connecting ring 62. A support ring 63 is rotatably connected to the rear end of the outer shell 1.

[0020] The motor 51 drives the nozzle 53 to rotate via the transmission wheel 52 and the transmission belt 54, thereby enabling the nozzle on the nozzle 53 to rotate behind the activated carbon 45. This ensures that the flue gas entering the nozzle 53 through the connecting pipe 61 and the connecting ring 62 is evenly sprayed onto the surface of the activated carbon 45, ensuring that the activated carbon 45 is in uniform contact with the flue gas, improving the flue gas purification efficiency, and avoiding the situation where some of the activated carbon 45 is not fully involved in flue gas purification, thus improving the utilization rate of the activated carbon 45.

[0021] The pipe assembly 2 includes an air inlet pipe 21 and an air outlet pipe 22. The air inlet pipe 21 is fixedly installed at the right end of the outer casing 1, and the air outlet pipe 22 is fixedly installed at the left end of the outer casing 1.

[0022] The exhaust pipe 22 is connected to the left end of the fixed pipe 41, and the intake pipe 21 is connected to the connecting pipe 61. The flue gas enters the connecting assembly 6 through the exhaust pipe 22, then enters the filter assembly 4, and is discharged through the exhaust pipe 22.

[0023] The left end of the outer casing 1 is fixedly installed with a discharge assembly 3, which includes an exhaust fan 31. The exhaust fan 31 is located on the left side of the outer casing 1 and is connected to the exhaust pipe 22. The output end of the exhaust fan 31 is fixedly connected to the exhaust pipe 32.

[0024] The induced draft fan 31 draws the purified flue gas into the exhaust pipe 32 through the exhaust pipe 22, and then discharges it through the exhaust pipe 32.

[0025] Sensor 9 is fixedly installed at the bottom of the discharge pipe 32.

[0026] By setting sensor 9 to monitor the composition of the flue gas emitted in the emission pipe 32 in real time, if the composition of the emitted flue gas does not meet the standards, the equipment needs to be repaired, thus achieving the effect of intelligent monitoring.

[0027] Among them, a limiting ring 43 is fixedly installed at the front end of the fixed tube 42, and the inner diameter of the limiting ring 43 is smaller than the diameter of the activated carbon 45.

[0028] The activated carbon 45 is limited by the limiting ring 43 to prevent it from being inserted too deeply during installation.

[0029] The isolation ring 44 has an opening at its left end, the depth of which is the same as the length of the isolation ring 44. The vertical projection of the fixed positions of the air outlet pipe 22 and the fixed pipe 41 is located inside the opening.

[0030] By setting an opening, the purified flue gas can enter the exhaust pipe 22 through the gap between the opening and the fixed pipe 41, and the movement of the activated carbon 45 will not affect the exhaust of the exhaust pipe 22 after the activated carbon 45 moves backward.

[0031] Two positioning rings 64 are respectively inserted into the inner cavities of the support ring 63 and the nozzle 53, and the connecting pipe 61 is connected to the air intake pipe 21.

[0032] The support ring 63 and the nozzle 53 are connected by a positioning ring 64. The surface of the nozzle 53 is provided with a support frame for positioning the nozzle 53 and the fixing pipe 42 in the horizontal direction.

[0033] Among them, the left end of the inner cavity of the fixed tube 42 is fixedly installed with an ejection assembly 7, which includes a positioning frame 71. A gear 72 is rotatably connected to the middle of the positioning frame 71. A lead screw 73 is meshed in the inner cavity of the gear 72. A rack 74 is fixedly installed at the rear end of the nozzle 53. A maintenance door 8 is hinged to the front end of the outer shell 1.

[0034] By setting the rack 74, during the flue gas purification process, the nozzle 53 rotates to evenly spray the flue gas onto the activated carbon 45. Therefore, the rotation of the nozzle 53 can drive the rack 74 to rotate. Each rotation of the rack 74 drives the gear 72 to rotate at a certain angle, which in turn drives the lead screw 73 to extend forward a certain distance. When the activated carbon 45 reaches the replacement cycle, the movement of the lead screw 73 will push the activated carbon 45 forward to contact the maintenance door 8. At this time, the maintenance door 8 can be opened to directly remove the activated carbon 45 for replacement. The operation is simple and convenient.

[0035] Among them, the rack 74 meshes with the gear 72, the lead screw 73 is located on the rear side of the activated carbon 45, and rectangular grooves are opened at both the upper and lower ends of the lead screw 73. A positioning strip 75 is slidably connected in the rectangular groove, and the positioning strip 75 is fixedly installed on the right end of the positioning frame 71.

[0036] By setting the positioning bar 75, the lead screw 73 can be positioned vertically, preventing the lead screw 73 from rotating with the gear 72, thus ensuring that the lead screw 73 can only move back and forth.

[0037] A method for using an intelligent asphalt fume purification device utilizing activated carbon adsorption, the method comprising the following steps: The right end of the air inlet pipe 21 is connected to a dust suppression spray system, an oil-water separator, a photo-oxidation system, a plasma system, and an electrostatic capture system. These systems are used to remove harmful substances such as CO2, H2S, and SO2 from the fumes produced during asphalt production. These molecular-level gaseous pollutants are treated and the flue gas enters the inlet pipe 21. After being transported through the inlet pipe 21 to the connecting pipe 61, the flue gas enters the connecting ring 62. Since the rear end of the support ring 63 is in a closed state, the flue gas will enter the nozzle 53. During the purification process, the motor 51 drives the nozzle 53 to rotate through the transmission wheel 52 and the transmission belt 54. At this time, since multiple nozzles are installed at equal intervals at the front end of the nozzle 53, the nozzles can spray the flue gas evenly onto the activated carbon 45. The suction force generated by the working of the induced draft fan 31 can drive the flue gas to flow. When the flue gas enters the activated carbon 45, the activated carbon 45 further adsorbs and filters the residual harmful substances in the flue gas. After being filtered by activated carbon 45, the flue gas enters the exhaust pipe 32 through the induced draft fan 31. The flue gas composition is detected by sensor 9 in the exhaust pipe 32. Sensor 9 is a Xuedilong SDM-Multi-UV multi-component ultraviolet sensor or a Siemens 7MB2521 multi-component infrared / ultraviolet composite sensor. During the flue gas purification process, the rotation of the nozzle 53 will drive the rack 74 to rotate. Each rotation of the rack 74 will drive the gear 72 to rotate at a certain angle. As the purification continues, the lead screw 73 will move forward continuously. When the lead screw 73 contacts the activated carbon 45, the forward movement of the lead screw 73 can drive the activated carbon 45 to move forward. When the activated carbon 45 moves to contact the maintenance door 8, the activated carbon 45 extends out of the isolation ring 44. At this time, there is a gap between the activated carbon 45 and the fixed pipe 41. After opening the maintenance door 8, the operator can directly pull out and replace the activated carbon 45 through this gap. After the replacement is completed, the motor 51 drives the nozzle 53 to rotate rapidly in the opposite direction, resetting the lead screw 73.
