Description

Technical Field

[0001] The invention belongs to the technical field of chemical fiber rope net production, in particular to a waste gas treatment device for chemical fiber rope net production. Background Art

[0002] During the production of chemical fiber rope nets, the waste gas generated contains smoke, dust, VOC substances (benzene, toluene, ethylbenzene and other hydrocarbon substances). The waste gas has a high pollution intensity, a large emission volume, and complex and variable pollution components. In particular, the odorous components in the waste gas are likely to cause significant pollution to the atmospheric environment and the factory environment. The existing technology can use activated carbon adsorption to purify the waste gas.

[0003] A patent with the announcement number CN213853772U discloses a waste gas treatment device for chemical fiber rope net production. Through the comprehensive use of activated carbon treatment box, UV photocatalytic waste gas treatment equipment and spray tower, the waste gas generated by chemical fiber rope net production can be effectively absorbed and treated, and discharged in compliance with standards, avoiding harm to the human body and pollution to the environment. By setting an air flow distributor in the spray tower, the air flow can be made more uniform, and the defogger effect of the defogger can be improved. The equipment occupies a small area, has good purification effect and high efficiency.

[0004] In the above-mentioned prior art, when using an activated carbon treatment box to purify waste gas, due to the limited adsorption capacity of the activated carbon, the activated carbon needs to be desorbed regularly to restore its adsorption capacity.

[0013] Preferably, a material taking assembly is provided on one side of the filter assembly, and the material taking assembly comprises a third rectangular plate rotatably connected between the two filter plates and away from the side of the first rectangular plate.

The activated carbon can be quickly discharged by driving the cylindrical rod to rotate and simultaneously driving multiple third rectangular plates to rotate. After all the activated carbon is discharged, the new activated carbon is discharged into the third circular tube through each second circular tube and into between each group of filter plates. The second circular tube is placed tilted downward, so that the activated carbon can be quickly filled between the two filter plates, and the automatic discharge of the activated carbon and subsequent automatic filling can be realized.

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods. Embodiment 1

[0022] like Figure 1-Figure 4 As shown, a waste gas treatment device for chemical fiber rope net production described in an embodiment of the present invention includes an air collecting hood 4, which is connected to a first filter device through a connecting pipe 41, and the first filter device includes two side panels 1, and rectangular frames 15 are fixedly connected on both sides of the two side panels 1 respectively, and multiple groups of filter components are arranged between the two side panels 1, and the filter components include two filter plates 2 arranged between the two side panels 1, and activated carbon is placed between the two filter plates 2, and the upper and lower ends of the two side panels 1 are fixedly connected with conical blocks 16 respectively, and the upper ends of the conical blocks 16 at the upper ends are respectively provided with smoke exhaust pipes 11, and the conical blocks 16 at the lower ends are fixedly connected with a first circular tube 121 through a smoke inlet 12, and the first circular tube 121 is connected to the connecting pipe 41, and a closing component is installed in the middle of the smoke inlet 12, and the closing component is used to control the closure of the inside of 12, and a second filter device is arranged on one side of the first filter device, and the structure of the second filter device is consistent with that of the first filter device.

[0023] Specifically, when using activated carbon to treat the waste gas generated during the production of chemical fiber rope nets, when the activated carbon adsorbs more impurities, the adsorption effect of the activated carbon will become poor, and the activated carbon needs to be desorbed to remove the impurities in the activated carbon and restore the adsorption capacity of the activated carbon. In the prior art, when the activated carbon is desorbed, it is necessary to stop the machine for treatment, which leads to low working efficiency. When using the waste gas treatment device, the waste gas is passed into the gas collecting hood 4, and then the waste gas is discharged into the connecting pipe 41. At this time, the closing component in the middle of the smoke inlet 12 near the side of the first filter device is in an open device, and the closing component can use a valve. Then the waste gas is passed into the first filter device through the smoke inlet 12, and the closing component in the middle of the smoke inlet 12 near the side of the second filter device is in a closed state. Then the gas floats from the bottom to the top and passes through multiple groups of filter plates 2. Since activated carbon is placed between each group of filter plates 2, the activated carbon placed is columnar activated carbon. The waste gas passes through multiple layers of activated carbon. The activated carbon can Impurities in the air are adsorbed. When the activated carbon in the first filter device absorbs more impurities, the activated carbon needs to be desorbed. The closing component inside the chimney 12 at the lower end of the first filter device is driven to be in a closed state, so that the chimney 12 is in a closed state, so that the exhaust gas cannot enter the first filter device, and the exhaust gas enters the second filter device through the chimney 12 on the other side. The activated carbon in the second filter device can filter the exhaust gas and the activated carbon in the first filter device can be desorbed at the same time. Water vapor can be used to desorb the activated carbon. The main reason is that water vapor is used to flush the activated carbon, and the relative humidity in the activated carbon is increased to weaken the binding force between the adsorbed substance and the activated carbon, thereby desorbing the adsorbed substance. A second filter device is set next to the first filter device, which can be used in rotation. When the activated carbon in one of the devices is desorbed, there is no need to stop the machine for treatment, and the exhaust gas can be continuously purified and adsorbed to improve work efficiency.

[0024] like Figure 5 As shown, the end of the connecting pipe 41 away from the air collecting hood 4 is fixedly connected to the dust collector 3, and the dust collector 3 is fixedly connected to the end of the first circular tube 121.

[0025] Specifically, the exhaust gas passes through the air collecting hood 4 through the connecting pipe 41, and then the exhaust gas passes through the dust collector 3. The dust collector 3 can be a bag filter. The bag filter intercepts most of the granular impurities in the exhaust gas, and then the filtered gas is discharged from the first circular pipe 121 into the first filter device for purification and adsorption by activated carbon. By setting the dust collector 3 to first filter most of the granular impurities in the exhaust gas, and then the gas enters the first filter device for secondary filtration, the contact between the granular impurities and the activated carbon can be reduced, and the adsorption effect and service life of the activated carbon can be extended.

[0026] like Figure 3As shown, the closing assembly includes a first valve 122 installed in the middle of the smoke exhaust pipe 11 and the smoke inlet pipe 12 respectively.

[0027] Specifically, when it is necessary to desorb the activated carbon in the first filter device and the second filter device, the first valve 122 at the corresponding position is rotated to make the smoke exhaust pipe 11 and the smoke inlet pipe 12 of the device in a closed state, and then the desorption treatment can be carried out. The activated carbon in the first filter device and the second filter device can be desorbed alternately.

[0028] like Figure 3 , Figure 5 As shown, the two conical blocks 16 at the upper end are commonly fixed to two first U-shaped tubes 13, and the two conical blocks 16 at the lower end are commonly fixed to two second U-shaped tubes 14. The first U-shaped tube 13 and the second U-shaped tube 14 respectively penetrate the conical blocks 16 and are connected to the middle parts of the two side plates 1. The middle part of the first U-shaped tube 13 on one side is fixed to the steam box 1321 through the first L-shaped tube 132, and the first U-shaped tube 13 on the other side is fixed to the condenser 1322 through the first L-shaped tube 132, the second U-shaped tube 14 on one side is fixed to the collecting box 1421 through the second L-shaped tube 142, and the second U-shaped tube 14 on the other side is fixed to the drying fan 1422 through the second L-shaped tube 142.

[0029] Specifically, when it is necessary to desorb the activated carbon in the first filter device, close the first valve 122 at the corresponding position, open the first valve 122 corresponding to the second filter device, and allow the exhaust gas to pass into the second filter device. Then, start the steam box 1321 to generate high-temperature steam, and allow the high-temperature steam to pass into the first filter device. The steam contacts the activated carbon. The steam contains water, which heats the activated carbon bed to gasify the adsorbed organic components and desorb them from the activated carbon. The water absorbs impurities and separates them from the activated carbon, falls into the conical block 16 at the lower end, and then flows into the second L-shaped tube 142 through the second U-shaped tube 14 on one side, and is finally collected by the collecting box 1421. When the desorption is completed, start the drying fan 1422 on one side to dry the water in the activated carbon, so that the activated carbon returns to a dry state and restores the adsorption capacity of the activated carbon. During the desorption process, the temperature inside the first filter device is detected in real time. When the internal temperature is detected to be high, start the condenser 1322 in time to cool the interior to prevent the high temperature from causing danger.

[0030] like Figure 5 As shown, the first L-shaped tube 132 is located in the middle of the first U-shaped tube 13, the second L-shaped tube 142 is located in the middle of the second U-shaped tube 14, the second valve 131 is installed on both sides of the first U-shaped tube 13, and the third valve 141 is installed on both sides of the second U-shaped tube 14.

[0031] Specifically, in the working state, the second valve 131 and the third valve 141 are both in the closed state. When it is necessary to desorb the activated carbon in the first filter device or the second filter device, the second valve 131 and the third valve 141 close to the device that needs desorption are driven to open, so that high-temperature water vapor can enter the device and contact the activated carbon for desorption. When the activated carbon in one of the devices is desorbed, it will not affect the normal exhaust gas purification work of the other device.

[0032] like Figure 6-Figure 7 As shown, each group of filter components is fixedly connected by a second rectangular plate 22, and the upper and lower ends of both sides of the side plate 1 are respectively fixedly connected with a fourth rectangular plate 24, and the filter plates 2 located at the upper and lower ends can slide in the fourth rectangular plate 24 through the second rectangular plate 22 respectively, and the fourth rectangular plate 24 located at the lower end is fixedly connected to the second rectangular plate 22 by a spring 241, and a switch 242 is provided inside the fourth rectangular plate 24.

[0033] Specifically, in the initial state, the spring 241 in the fourth rectangular plate 24 pushes the second rectangular plate 22 at the bottom upward and keeps it stable. The second rectangular plate 22 drives the activated carbon between each group of filter plates 2 to remain stable. Under normal working conditions, the activated carbon has a developed pore structure inside. When the exhaust gas passes through each layer of activated carbon for purification, it can pass through the activated carbon and keep the activated carbon stable without causing large shaking. When the activated carbon adsorbs more impurities, more impurities are absorbed in the pores inside the activated carbon, and the weight of the activated carbon becomes heavier. When the weight of the activated carbon becomes heavier, it is necessary to desorb the activated carbon in time. When the weight of the activated carbon is heavy, the activated carbon drives the second rectangular plate 22 to slide inside the fourth rectangular plate 24 at the lower end through the filter plate 2, and at the same time squeezes the spring 241. When the second rectangular plate 22 at the lower end slides to the lower end inside the fourth rectangular plate 24, it touches the switch 242 to remind the staff to come and check and desorb the activated carbon in time.

[0034] like Figure 6 As shown, a material taking assembly is provided on one side of the filter assembly, and the material taking assembly includes a third rectangular plate 23 rotatably connected between the two filter plates 2 and away from the first rectangular plate 21 .

[0035] Specifically, the service life of activated carbon is limited. After long-term use and multiple desorption treatments, the adsorption performance of the activated carbon will be greatly reduced, and all the activated carbon needs to be replaced. By driving the third rectangular plate 23 to rotate, the activated carbon between the two filter plates 2 can be pulled out, and then new activated carbon can be refilled between the two filter plates 2. At the same time, the first filter device and the second filter device can be replaced in turn without stopping the machine for treatment, and the exhaust gas purification can be continuously performed.

[0036] like Figure 6As shown, the third rectangular plate 23 is located at the lower inclined side of the filter plate 2 , and a cylindrical rod 231 is fixedly connected to the middle of a plurality of third rectangular plates 23 .

[0037] Specifically, the filter plate 2 is tilted. Since the third rectangular plate 23 is located at a lower part of the filter plate 2, when the third rectangular plate 23 is driven to rotate, the activated carbon slides to the lowest point along the inclined edge and is pulled out by the third rectangular plate 23. By driving the cylindrical rod 231 to rotate and simultaneously driving multiple third rectangular plates 23 to rotate, the activated carbon can be quickly discharged, and the automatic discharge of the activated carbon can be achieved.

[0038] like Figure 4 As shown, a discharge port 152 is provided on one side of the rectangular frame 15 close to the third rectangular plate 23 , and a bevel block 151 is fixedly connected inside the rectangular frame 15 .

[0039] Specifically, all the activated carbon pulled out falls into the rectangular frame 15, and then slides along the bevel block 151 provided in one side of the rectangular frame 15 to the discharge port 152, and then is discharged from the discharge port 152, and is collected and prevented from scattering. Embodiment 2

[0040] like Figure 6 As shown, compared with Example 1, another implementation of the present invention is: a second circular tube 211 is fixedly connected to the middle of a plurality of first rectangular plates 21 respectively, the second circular tube 211 is arranged to be inclined downward, and a third circular tube 212 is fixedly connected to the plurality of second circular tubes 211 together.

[0041] Specifically, after all the activated carbon is discharged, new activated carbon is then discharged into the third circular tube 212 through each second circular tube 211 and discharged into between each group of filter plates 2. The second circular tube 211 is placed tilted downward, so that the activated carbon can be quickly filled between the two filter plates 2, thereby realizing automatic filling of the activated carbon and improving work efficiency.

[0042] Working principle: the exhaust gas is passed into the air collecting hood 4, and then the exhaust gas is discharged into the connecting pipe 41, and then the exhaust gas passes through the dust collector 3, and the dust collector 3 can be a bag filter, and the bag filter intercepts most of the granular impurities in the exhaust gas, and then the filtered gas is discharged from the first circular tube 121 into the first filter device, and then the gas floats from bottom to top and passes through multiple groups of filter plates 2. Since activated carbon is placed between each group of filter plates 2, the activated carbon placed is columnar activated carbon. The exhaust gas passes through multiple layers of activated carbon, and the activated carbon can adsorb impurities in the exhaust gas. When the activated carbon in the first filter device absorbs more impurities, the activated carbon needs to be desorbed; When more impurities are adsorbed by the activated carbon, the weight of the activated carbon becomes heavier. When the weight of the activated carbon becomes heavier, it is necessary to desorb the activated carbon in time. When the weight of the activated carbon is large, the activated carbon drives the second rectangular plate 22 to slide inside the fourth rectangular plate 24 at the lower end through the filter plate 2, and at the same time squeezes the spring 241. When the second rectangular plate 22 at the lower end slides to the lower end of the fourth rectangular plate 24, the switch 242 is touched to remind the staff to come and check and desorb the activated carbon in time. By rotating the first valve 122 at the upper and lower ends of the first filter device that needs to be desorbed, the smoke exhaust pipe 11 and the smoke inlet pipe 12 of the first filter device are in a closed state, so that the exhaust gas cannot pass into the first filter device, and the exhaust gas passes through the second filter device on the other side for purification. In the working state, the second valve 131 and the third valve 141 are all in a closed state, and then the second valve 131 and the third valve 141 close to the first filter device that needs to be desorbed are driven to open, so that the high-temperature water vapor can enter the first filter device and contact with the activated carbon for desorption treatment. When the activated carbon in the first filter device is desorbed, it will not affect the normal exhaust gas purification work of the second filter device; When the steam box 1321 is started to generate high-temperature steam, the high-temperature steam is passed into the first filtering device, the steam contacts the activated carbon, the steam contains water, and heats the activated carbon bed, so that the adsorbed organic components are gasified and desorbed from the activated carbon, the water absorbs the impurities and separates them from the activated carbon, falls into the conical block 16 at the lower end, and then flows into the second L-shaped tube 142 through the second U-shaped tube 14 on one side, and is finally collected by the collecting box 1421. When the desorption is completed, the drying fan 1422 on one side is started to dry the water in the activated carbon, so that the activated carbon returns to a dry state and the adsorption capacity of the activated carbon is restored. During the desorption process, the temperature inside the device is detected in real time. When the internal temperature is detected to be high, the condenser 1322 is started in time to cool down the inside of the device to prevent the high temperature of the device from causing danger; The service life of activated carbon is limited. After long-term use and multiple desorption treatments, the adsorption performance of activated carbon will be greatly reduced. All activated carbon needs to be replaced. By driving the cylindrical rod 231 to rotate and driving multiple third rectangular plates 23 to rotate at the same time, the activated carbon can be quickly discharged. All the activated carbon pulled out falls into the rectangular frame 15, and then slides along the bevel block 151 provided in one side of the rectangular frame 15 to the discharge port 152, and then is discharged from the discharge port 152 for centralized collection to prevent scattering. After all the activated carbon is discharged, new activated carbon is then discharged into the third circular tube 212 through each second circular tube 211 and discharged into between each group of filter plates 2. The second circular tube 211 is placed tilted downward, so that the activated carbon can be quickly discharged between the two filter plates 2.
