Description

Technical Field

[0001] The present invention relates to the technical field of flue gas treatment, and in particular to a catalytic oxidation reactor with a porous uniform flow structure and a flue gas treatment method. Background Art

[0002] Waste gas treatment refers to the pre-treatment of waste gas generated in industrial sites and factory workshops before external discharge to meet the national standards for waste gas external discharge. General waste gas treatment includes organic waste gas treatment, dust waste gas treatment, acid and alkali waste gas treatment, odor waste gas treatment and air sterilization and purification, which can effectively remove organic waste gas such as benzene, toluene, xylene, ethyl acetate, acetone, butanone, ethanol, acrylic acid, formaldehyde, and acid and alkali waste gas such as hydrogen sulfide, sulfur dioxide, and ammonia generated in factory workshops.

[0003] A waste gas catalytic oxidation reactor disclosed in a patent application with reference publication number CN210934476U includes a fixed bracket, a reaction tank body connected to the fixed bracket by a reinforcing support leg, an air intake pipe arranged on one side of the upper end of the reaction tank body, an exhaust pipe arranged at the lower end of the reaction tank body, a stirring shaft arranged in the reaction tank body, and a driving component for driving the stirring shaft. The reaction tank body is provided with a reactant for catalytic reaction of the waste gas. The utility model is a waste gas catalytic oxidation reactor, which is convenient for draining the waste gas into the reaction tank body through the air intake pipe, and driving the stirring shaft through the driving component, thereby driving the driving shaft to fully catalyze the waste gas and the reactant, and discharging the treated waste gas through the exhaust pipe.

[0004] There are a lot of large particles in the exhaust gas. Before the exhaust gas is catalytically oxidized, the large particles in the gas need to be filtered. The existing filtration is often done by setting up a filter. After the filtration, the equipment needs to be paused regularly to clean the filter, causing the processing equipment to be paused. After the gas is catalytically oxidized, the gas is often detected by a sensor to detect whether it meets the standards. During the detection process, a large amount of gas will remain outside the detection sensor, which can easily cause detection errors when the subsequent gas is detected, resulting in the discharge of substandard gas.

When the detection meets the standard, the solenoid valve 801 on the outside of the exhaust pipe 8 is opened. When it does not meet the standard, the control valve arranged on the outside of the secondary return pipe 7 is opened, and the flue gas is re-flushed into the catalytic oxidation cylinder 5 for treatment. One-way control valves are installed on the outside of the first branch pipe 601 and the secondary return pipe 7 to avoid gas backflow. By detecting the gas, it is ensured that the gas meets the qualified standard when it is discharged, so that the gas that does not meet the standard is re-processed.

[0049] The cleaning assembly also includes a first gear ring 3072 fixedly connected to the outer side of the rotating frame 307, the outer side of the first gear ring 3072 is meshed with a first gear 3073, the first gear 3073 is fixedly connected to the outer side of the transmission rod 303, a plurality of first telescopic rods 3075 are fixedly connected to the inner wall of the dust outlet pipe 306, the bottom ends of the plurality of first telescopic rods 3075 are fixedly connected to a knocking frame 3074, a first spring 3076 is sleeved on the outer side of the first telescopic rod 3075, and the two ends of the first spring 3076 are respectively fixedly connected to the knocking frame 3074 and the dust outlet pipe 306, the knocking frame 3074 is in contact with the cleaning frame 3071, the knocking frame 3074 is rotatably connected with a contact roller 3077, and a plurality of extrusion plates 3078 are fixedly connected to the top of the cleaning frame 3071, when the contact roller 3077 is in contact with the extrusion plate 3078, the extrusion plate 3078 is raised, and the cleaning frame 3071 is knocked by the falling of the knocking frame 3074.

[0050] During specific implementation, when the flue gas in the air intake main pipe 2 passes through the filter disc 302 inside the fixed support frame 3, the filter disc 302 blocks and filters the large particles in the flue gas to prevent dust from remaining in the subsequent processing pipeline. When the filtered gas passes into the connecting pipe 4, after one of the filter discs 302 has been filtered for a long time, the filtering effect decreases. At this time, the driving motor 304 is started, and the output shaft of the driving motor 304 drives the rotating disc 301 to rotate. The rotation of the rotating disc 301 drives the filter disc 302 to switch, so that the filtered filter disc 302 rotates to the bottom of the rotating frame 307. During the rotation, the hair dryer 308 is started, and the hair dryer 308 blows air upward to blow back the filtered material on the filter disc 302, so that it is discharged to the outside through the dust outlet pipe 306, and a cleaning rack 3071 is fixedly connected to the rotating frame 307. The cleaning rack 3071 is When the movable rod 303 rotates, a brush is fixedly connected to the bottom of the cleaning frame 3071, and the first gear ring 3072 is driven to rotate through the first gear 3073, and then the cleaning frame 3071 is rotated, so that the surface of the filter plate 302 is cleaned, and the air blowing of the hair dryer 308 is combined to improve the cleaning effect; and when the rotating frame 307 rotates, the contact roller 3077 is continuously squeezed by the multiple squeezing plates 3078 on the cleaning frame 3071, so that the contact roller 3077 pushes the knocking frame 3074 to rise. Since the squeezing plates 3078 are set to be a right-angled triangle, after the contact roller 3077 moves on the inclined plane, it is suddenly supported, so that the device quickly drops under the action of the first spring 3076, so that the knocking frame 3074 knocks on the cleaning frame 3071, which can make the dust on the cleaning frame 3071 vibrate and fall, and be blown away by wind force, thereby ensuring the cleaning effect of the cleaning frame 3071.

[0051] like Figures 7 to 9 As shown, in the third embodiment, two ends of the second branch pipe 603 are fixedly connected to the exhaust main pipe 8 and the detection tube 6 respectively, and a control valve 604 is installed on the outside of the second branch pipe 603 .

[0052] The purification component includes a reciprocating screw rod 605 and a limiting rod 606 that penetrate the detection tube 6. The reciprocating screw rod 605 is rotatably connected to the detection tube 6. The reciprocating screw rod 605 is fixedly connected to the detection tube 6. A moving ring 607 is arranged inside the detection tube 6. The reciprocating screw rod 605 penetrates the moving ring 607 and is connected to the moving ring 607 through a ball nut pair. The limiting rod 606 penetrates the moving ring 607 and is slidably connected to the moving ring 607. A rotating ring 6071 is rotatably connected to the bottom of the moving ring 607. A plurality of scrapers 6072 are fixedly connected to the outer side of the rotating ring 6071. The rotating ring 6071 is fixedly connected to the outer side of the rotating ring 6071. A first inner gear ring 6073 is fixedly connected inside 71, and a second gear 6074 is meshedly connected inside the first inner gear ring 6073. The second gear 6074 is rotatably connected to the bottom of the rotating ring 6071 and sleeved on the outside of the reciprocating screw 605. A transverse groove is opened on the outside of the reciprocating screw 605. A limiting block is fixedly connected to the inner wall of the reciprocating screw 605. The limiting block extends to the inside of the transverse groove and slidably cooperates with the reciprocating screw 605. A micro motor 600 is fixedly connected to the outside of the detection tube 6, and the output shaft of the micro motor 600 is connected to the reciprocating screw 605 through a transmission member.

[0053] The purification component also includes a connecting frame 608 fixedly connected to the bottom of the rotating ring 6071, and multiple nozzles are arranged on the inside and outside of the connecting frame 608.

A second telescopic rod 6082 is fixedly connected between the cover plate 6081 and one end of the detection tube 6. A water pipe 6083 is fixedly connected to the bottom of the cover plate 6081. The water pipe 6083 passes through the detection tube 6 and is fixedly connected to an external water supply pipe.

[0054] In a specific implementation, when the gas detection sensor 602 completes the detection of the processed gas, the control valve 604 is closed to prevent the gas from entering the detection tube 6. Then, the micro motor 600 is started to drive the reciprocating screw 605 to rotate through the output shaft of the micro motor 600. The reciprocating screw 605 drives the moving ring 607 inside the detection tube 6 to reciprocate. When the reciprocating screw 605 rotates, the limit block on the inner side of the second gear 6074 is inside the transverse groove, thereby driving the second gear 6074 to rotate. When the second gear 6074 rotates, it drives the first inner gear ring 6073 engaged in the rotation. The first inner gear ring 6073 rotates to drive the outer rotating ring 6071, and the rotating ring 6071 is fixedly connected to a plurality of scrapers 6072 to rotate, and then the scrapers 6072 scrape the inside of the detection tube 6, and a connecting frame 608 is fixedly connected to the bottom of the rotating ring 6071, and cleaning water is transported to the connecting frame 608 through a water pipe 6083, and a drain valve 6084 is installed on the outside of the detection tube 6, and the inside of the detection tube 6 is cleaned through the nozzles inside and outside the connecting frame 608, thereby ensuring that there is no residue inside the detection tube 6 each time the detection is detected, thereby improving the detection accuracy of the gas detection sensor 602.

[0055] like Figure 10 to Figure 11 As shown, in the fourth embodiment, the third gear 901 is fixedly connected to the outer side of the reciprocating screw 605, the outer side of the third gear 901 is meshedly connected to the second outer gear ring 903, a plurality of fixed rods 905 are fixedly connected to the inner side of the second outer gear ring 903, a plurality of cleaning plates 906 are slidably connected to the outer side of the fixed rod 905, a second spring 911 is fixedly connected between the cleaning plate 906 and the second outer gear ring 903, the second spring 911 is sleeved on the outer side of the fixed rod 905, a brush is arranged on the cleaning plate 906 near the gas detection sensor 602, and the second outer A plurality of transverse plates are fixedly connected to the inner side of the gear ring 903, a fourth gear 907 is rotatably connected to the top of the transverse plate, a fixed plate 908 is fixedly connected to the top of the fourth gear 907 via a one-way damping bearing, a driving shaft 909 is fixedly connected to the top of the fixed plate 908, a moving frame 910 is sleeved on the outer side of the driving shaft 909 and is slidably connected to the moving frame 910, the moving frame 910 is fixedly connected to the cleaning plate 906, a second inner gear ring 904 is fixedly connected to the bottom end of the inner part of the detection tube 6, and the second inner gear ring 904 is meshingly connected to the plurality of fourth gears 907.

[0056] During specific implementation, in order to ensure the accuracy of detection of the gas detection sensor 602, when the reciprocating screw 605 rotates, it drives the third gear 901 fixedly connected on the outside to rotate, and the rotation of the third gear 901 drives the meshing second outer gear ring 903, and the second outer gear ring 903 drives the fixedly connected cross plate, so that the fourth gear 907 on the cross plate is meshed with the second inner gear ring 904. After the fourth gear 907 is meshed, the damping effect of the one-way damping bearing is used to rotate the fixed plate 908. When the fixed plate 908 rotates, the moving frame 910 is pushed through the top fixed connection push shaft 909, so that the moving frame 910 pushes the cleaning plate 906 to move back and forth, thereby cleaning the outside of the gas detection sensor 602 and cleaning the surface residue of the gas detection sensor 602. When the cleaning is completed, the fixedly connected cleaning plate 906 is driven by the second spring 911 to move away from the gas detection sensor 602, thereby avoiding the cleaning plate 906 from affecting the detection of the gas detection sensor 602.

[0057] In this embodiment, one end of the detection tube 6 is fixedly connected to a fixed frame 6092, and one side of the movable ring 607 is fixedly connected to an extrusion frame 609, the extrusion frame 609 passes through the fixed frame 6092 and is slidably connected to the fixed frame 6092, an airbag 6091 is fixedly connected between the fixed frames 6092 and 6092, a branch pipe is fixedly connected between the airbag 6091 and the detection tube 6, a one-way air inlet valve is installed on the outside of the airbag 6091, and a one-way air outlet valve is installed on the outside of the branch pipe.

[0058] In specific implementation, when the movable ring 607 moves, it drives the fixedly connected extrusion frame 609 to move, and the extrusion frame 609 compresses the airbag 6091 between the fixed frames 6092, rushes the pure gas into the detection tube 6, discharges the processed gas inside the detection tube 6, and detects the accuracy of the gas detection sensor 602, so as to judge the cleaning effect.

[0059] A flue gas treatment method is also provided, comprising the following steps:

[0060] Step 1: The smoke is passed into the air inlet main pipe 2, filtered through the filter disc 302 provided in the fixed support frame 3 inside the fixed support frame 3, and discharged into the connecting pipe 4;

[0061] Step 2: After passing into the catalytic oxidation tube 5, the catalytic reactant in the catalytic oxidation tube 5 catalytically oxidizes the substances in the flue gas, and the treated gas is discharged into the exhaust pipe 8;

[0062] Step three, open the control valve 604 to allow the gas to pass into the detection tube 6, and detect the gas through the gas detection sensor 602 inside the detection tube 6. When the detection meets the standard, open the solenoid valve 801 on the outside of the exhaust main pipe 8. When it does not meet the standard, open the control valve set on the outside of the secondary return pipe 7 and re-flush the gas into the catalytic oxidation tube 5 for treatment.
