Description

Technical Field

[0001] This invention relates to the field of advanced environmental protection industry technology, specifically to a device for purifying and treating waste gas from heat setting and drying of luggage leather. Background Technology

[0002] With the footwear, leather, and luggage manufacturing industry being listed as a key controlled industry and environmental standards becoming increasingly stringent, the effective treatment of such waste gas has become a critical issue that luggage and leather manufacturers urgently need to address. During the heat setting and drying process, a large amount of organic solvents evaporate, forming a composite heat setting and drying waste gas containing volatile organic compounds, oil mist, and particulate matter. Therefore, waste gas purification and treatment is a relatively important link in the environmental protection industry. For example, the patent with announcement number CN205867898U describes a sludge drying exhaust gas treatment device, which includes a sludge feeding conveyor, a drying furnace connected to the sludge feeding conveyor, an exhaust gas outlet above the drying furnace, an exhaust gas discharge pipe connected to the exhaust gas outlet, and a primary dust collector, a bag filter, a hydrocyclone dust collector, a comprehensive cleaning tower, and a chimney connected in sequence to the exhaust gas discharge pipe, so as to perform multiple purification and dust removal treatments on the exhaust gas before it enters the chimney for discharge, avoiding direct emission that would pollute the air and affect people's health; For example, patent CN119425360A discloses a method and system for treating exhaust gas from the foaming of artificial leather. The system sequentially includes a waste gas collection device, a filtration device, a cooling device, an electrostatic oil fume purification device, an exhaust fan, and a spray filtration device. The filtration device is a filter screen; the cooling device is a dry cooling device; the spray filtration box includes a main body, a circulating water tank I located below the main body, a water pump I located within the circulating water tank I, and a spray device and a water-oil separation baffle located within the main body. The spray device is connected to the water pump I. For example, the patent with publication number CN224404818U discloses a biomass drying exhaust gas purification system, which includes a wet scrubbing tower, a plasma purifier, an absorption tower, and a circulating water treatment device; the air inlet of the wet scrubbing tower is connected to the exhaust gas pipeline, the air outlet at the top of the wet scrubbing tower is connected to the air inlet of the plasma purifier through a pipeline, the air outlet of the plasma purifier is connected to the air inlet of the absorption tower through a pipeline, the air outlet of the absorption tower is connected to the induced draft fan through a pipeline, and the drain outlet of the wet scrubbing tower is connected to the water inlet of the circulating water treatment device through a pipeline. Most of the existing technologies mentioned above improve the overall structure. However, in the existing heat-setting and drying exhaust gas purification and treatment devices for luggage and bags, the traditional filter materials are mostly statically fixed during operation. When the exhaust gas passes through the filter material, the airflow path is relatively fixed, which easily forms a fixed airflow channel. This leads to uneven utilization of the filter material. The filter material in the airflow channel area is quickly saturated, while the material in other areas is not fully utilized, resulting in a shortened overall service life of the filter material and low purification efficiency, thus causing limitations in reaction efficiency. Summary of the Invention

[0003] The purpose of this invention is to provide a waste gas purification and treatment device for heat setting and drying of luggage and bags, in order to solve the problem mentioned in the background art that the filter materials are mostly statically fixed. When the waste gas passes through the filter material, the airflow path is relatively fixed, which easily forms a fixed airflow channel. This leads to uneven utilization of the filter material, rapid saturation of the filter material in the airflow channel area, while the material in other areas is not fully utilized, resulting in a shortened overall service life of the filter material, low purification efficiency, and poor reaction efficiency.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a waste gas purification and treatment device for heat setting and drying of luggage and bags, comprising a preset base, wherein the preset base is installed on the outside of the exhaust end of the drying equipment, and a docking blade is installed on the inner side of the upper end of the preset base; an external docking component is installed on the outside of the preset base, and the external docking component is docked with the shaft end of the docking blade; a first filter screen layer is installed on the lower inner end of the preset base; and a movable purification structure is provided inside the preset base, through which the transmitted gas is dynamically contact-filtered and purified.

[0005] Furthermore, the movable purification structure is provided with a connecting rod guide, which is installed on the outside of the external docking member. The lower end of the connecting rod guide is connected to a nested docking member, which is nested with the outside of the preset base. The lower end of the nested docking member is connected to a guide steel rope assembly, which is installed through the inner wall of the preset base.

[0006] Furthermore, the lower end of the first filter layer is connected to a flexible docking layer, and the lower end of the flexible docking layer is connected to a second filter layer. The outer side of the second filter layer is nested and docked with the inner wall of the preset substrate, and the outer end of the second filter layer is docked with the lower end of the guide steel rope assembly.

[0007] Furthermore, the external docking component drives the nested docking component to form a sliding structure along the outside of the preset base through the connecting rod guide component, and the nested docking component drives the second filter layer to form a traction structure through the guide steel rope assembly.

[0008] Furthermore, the second filter layer forms an up-and-down movable structure along the lower end of the first filter layer through a flexible docking layer, and spherical activated carbon filter material is uniformly distributed inside the first and second filter layers.

[0009] Furthermore, a heat recovery structure is provided at the upper end of the preset base to recirculate the stored waste heat. The heat recovery structure is provided with a nested built-in component, which is connected to the upper end of the nested docking component. The nested built-in component and the preset base are nested and docked. An air storage cavity is provided on the inner side of the upper end of the preset base. A return spring is fixedly connected inside the air storage cavity. The upper end of the return spring is connected to a fitting piston component. The lower end of the fitting piston component is connected to a built-in steel rope assembly. The built-in steel rope assembly runs through the inner wall of the preset base. The lower end of the built-in steel rope assembly is docked with the outer side of the nested built-in component.

[0010] Furthermore, a reserved through hole is provided on the outer side of the upper end of the air storage cavity, a heat-conducting plate is provided at the lower end of the air storage cavity, and a supply guide pipe is provided through the upper end of the first filter layer, and the supply guide pipe is provided through the inner side of the air storage cavity.

[0011] Furthermore, the nested docking component drives the nested built-in component to move vertically along the inner side of the preset base, and the nested built-in component drives the fitting piston component to form a traction structure through the built-in steel rope assembly. The fitting piston component moves vertically along the inside of the air storage cavity through the return spring.

[0012] Furthermore, after the fitting piston moves to the lower end of the reserved through hole, the interior of the gas storage cavity is in a closed state, and the continuously moving fitting piston, in conjunction with the supply guide pipe, transmits the gas to the space between the first filter layer and the second filter layer.

[0013] Compared with the prior art, the beneficial effects of the present invention are: This bag heat-setting and drying exhaust gas purification device features a movable purification structure. This structure dynamically contacts and filters the transmitted gas. As the exhaust gas passes through the interior of the device and reaches the top, it is discharged outwards with greater force through smaller transmission holes. The contact blades rotating in contact with the airflow rotate, and the externally connected components drive the connecting rod guide and nested components to slide back and forth along the outer side of the pre-set base. The nested components, guided by a steel rope assembly, drive the second filter layer in conjunction with the flexible connection layer to form an up-and-down movable structure. This continuously disturbs and agitates the spherical activated carbon filter material evenly distributed within the first, flexible, and second filter layers. As the exhaust gas passes through the filter material, the distribution of the airflow channels continuously changes, causing the contact path between the exhaust gas and the spherical filter material to constantly change. This avoids the formation of fixed airflow channels, significantly improving the effective utilization rate of the filter material and the overall purification efficiency. Compared to the static arrangement of filter materials in existing technologies, this device achieves dynamic disturbance multi-directional filtration, improving purification efficiency and material utilization. Furthermore, a heat recovery structure is provided to recirculate and transfer the stored waste heat. As the nested docking component reciprocates along the outer side of the preset base, its upper end will drive the nested inner component to move vertically along the inner side of the preset base. This, in turn, is driven by the built-in steel rope assembly to move the fitting piston component back and forth along the interior of the gas storage cavity. When the fitting piston component moves to the lower end of the reserved through hole, the interior of the gas storage cavity is sealed. The continuously moving fitting piston component, in conjunction with the supply guide pipe, transmits gas between the first and second filter layers. During the upward discharge of filtered hot gas, most of it will first contact the heat-conducting plate, which will effectively transfer the heat to the inside of the gas storage cavity for storage. Then, the transmitted waste gas will contact the heat-conducting plate and be discharged outward towards the middle. Therefore, the heat carried by the waste gas itself is stored inside the gas storage cavity and reused in the filtration process. After the hot gas enters between the first filter layer and the second filter layer, it will provide auxiliary constant temperature contact to the spherical filter material, so that the filter material is maintained in a suitable working temperature range, which will improve the adsorption activity, delay the saturation rate of the filter material, and extend its service life. Furthermore, after the airflow inside the storage cavity is transmitted to the first and second filter layers, the hot airflow and the reciprocating motion of the spherical filter material work together. The hot airflow generates fluid shear force on the surface of the spherical filter material, which, together with the upward mechanical reciprocating disturbance of the second filter layer, causes further relative displacement between the spherical filter materials. This effectively breaks down the bonding bridges formed between particles by oil mist condensation, inhibits the caking and agglomeration of the filter material, and maintains the loose state of the filter material and the unobstructed flow of the filter channel without the need for frequent disassembly and cleaning. This significantly extends the effective service life of the filter material, reduces operating and maintenance costs, and improves the practicality of the device. Attached Figure Description

[0016] 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.

[0017] Example 1: Please refer to Figures 1-9The present invention provides the following technical solution: a bag heat setting and drying exhaust gas purification treatment device, which solves the problem that filter materials are mostly statically fixed, and when exhaust gas passes through the filter material, the airflow path is relatively fixed, which easily forms a fixed airflow channel, resulting in uneven utilization of filter materials. The filter material in the airflow channel area is quickly saturated, while the material in other areas is not fully utilized, resulting in a shortened overall service life of the filter material and low purification efficiency, causing the limitation of poor reaction efficiency. The device discloses a device including: a preset base 1 installed on the outside of the exhaust end of the drying equipment, and a docking blade 2 installed on the inner side of the upper end of the preset base 1. An external docking member 3 is installed on the outer side of the preset base 1, and the external docking member 3 is docked with the shaft end of the docking blade 2. A first filter layer 7 is installed on the lower inner side of the preset base 1. A movable purification structure is provided inside the preset base 1. The gas to be transmitted is dynamically filtered and purified by the movable purification structure. The movable purification structure is provided with a connecting rod guide 4, which is installed on the outer side of the external docking member 3. The lower end of the connecting rod guide 4 is docked with a nested docking member 5. The nested docking member 5 is nested and docked with the outer side of the preset base 1. The lower end of the nested docking member 5 is... A guide steel rope assembly 6 is connected to the pre-set base 1. The guide steel rope assembly 6 passes through the inner wall of the pre-set base 1 and is connected to the lower end of the first filter layer 7. A flexible docking layer 8 is connected to the lower end of the flexible docking layer 8. A second filter layer 9 is connected to the lower end of the flexible docking layer 8. The outer side of the second filter layer 9 is nested with the inner wall of the pre-set base 1. The outer end of the second filter layer 9 is connected to the lower end of the guide steel rope assembly 6. The external docking member 3 drives the nested docking member 5 to form a sliding structure along the outer side of the pre-set base 1 through the connecting rod guide member 4. The nested docking member 5 drives the second filter layer 9 to form a sliding structure through the guide steel rope assembly 6. The traction structure, the second filter layer 9 forms an up-and-down movable structure along the lower end of the first filter layer 7 through the flexible docking layer 8. Spherical activated carbon filter material is evenly distributed inside the first filter layer 7 and the second filter layer 9. When the exhaust gas passes through the inside of the equipment and is transferred to the upper end, after passing through the first filter layer 7 and the second filter layer 9, it is discharged outward through the gradually shrinking cross-sectional area of ​​the guide cone hole at the upper end of the preset base 1. The airflow accelerates in the shrinking section and impacts the docking blade 2, causing it to rotate. Through the external docking part 3 on the outer side, it drives the connecting rod guide part 4 to engage with the nested docking part. The connector 5 slides back and forth along the outer side of the preset base 1, allowing the nested connector 5 to drive the second filter layer 9 to cooperate with the flexible connector layer 8 to form an up-and-down movable structure through the guide steel rope assembly 6. This causes the spherical activated carbon filter material evenly distributed inside the first filter layer 7, the flexible connector layer 8, and the second filter layer 9 to be continuously disturbed and turned. As the transmitted exhaust gas passes through the filter material, the distribution state of the airflow channel can be continuously changed, so that the contact path between the exhaust gas and the spherical filter material is continuously changed, avoiding the formation of a fixed airflow channel, and significantly improving the effective utilization rate of the filter material and the overall purification efficiency.

[0018] Example 2: Based on Example 1, a heat recovery structure is also disclosed, the specific structure of which is as follows: A heat recovery structure is provided at the upper end of the pre-built substrate 1 to transfer the stored waste heat back through the heat recovery structure. The heat recovery structure is provided with a nested built-in component 10, which is connected to the upper end of the nested connecting component 5. The nested built-in component 10 is nested and connected to the preset base 1. An air storage cavity 12 is provided on the inner side of the upper end of the preset base 1, and a return spring 13 is fixedly connected inside the air storage cavity 12. The upper end of the return spring 13 is connected to a fitting piston component 16, and the lower end of the fitting piston component 16 is connected to a built-in steel rope assembly 11. The built-in steel rope assembly 11 passes through the inner wall of the preset base 1, and the lower end of the built-in steel rope assembly 11 is connected to the outer side of the nested built-in component 10. The upper outer side of the air storage cavity 12 is open. A pre-reserved through hole 15 is provided. A heat-conducting plate 17 is provided at the lower end of the air storage cavity 12. A supply guide pipe 14 is provided through the upper end of the first filter layer 7, and the supply guide pipe 14 is provided through the inner side of the air storage cavity 12. As the nested docking member 5 moves back and forth along the outer side of the preset base 1, its upper end will drive the nested inner member 10 to move vertically along the inner side of the preset base 1. And through the built-in steel rope assembly 11, it drives the fitting piston member 16 to move back and forth along the inside of the air storage cavity 12. When the fitting piston member 16 moves to the lower end of the pre-reserved through hole 15, the inside of the air storage cavity 12 is in a closed state. The continuously moving fitting piston member 16 moves to the lower end of the pre-reserved through hole 15. The plug 16, in conjunction with the supply guide pipe 14, transmits gas between the first filter layer 7 and the second filter layer 9. As the transmitted filtered hot gas is discharged upwards, most of it will pre-contact the heat-conducting plate 17, effectively transferring heat to the inside of the gas storage cavity 12 for storage. The transmitted exhaust gas then contacts the heat-conducting plate 17 and is discharged outwards towards the center. Therefore, the gas storage cavity 12 stores the heat carried by the exhaust gas itself and reuses it in the filtration process. After the hot gas enters between the first filter layer 7 and the second filter layer 9, it provides auxiliary constant-temperature contact to the spherical filter material, maintaining the filter material within a suitable operating temperature range. This enhances adsorption activity. After the airflow inside the gas storage cavity 12 is transmitted to the first filter layer 7 and the second filter layer 9, the hot airflow and the reciprocating motion of the spherical filter material work synergistically. The hot airflow generates fluid shear force on the surface of the spherical filter material. Combined with the upward mechanical reciprocating disturbance of the second filter layer 9, this causes further relative displacement between the spherical filter materials. This effectively breaks down the bonding bridges formed between particles due to oil mist condensation, inhibits the caking and agglomeration of the filter material, and maintains the loose state of the filter material and the unobstructed flow of the filter channel without the need for frequent disassembly and cleaning, significantly extending the effective service life of the filter material.
