Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, and more specifically, to a waste gas treatment device for activated carbon regeneration. Background Technology

[0002] Activated carbon, with its porous structure, is widely used in the adsorption of impurities in water and air. However, its adsorption capacity gradually becomes saturated with use, requiring regeneration to restore its performance. Currently, the mainstream methods for activated carbon regeneration include thermal regeneration, chemical regeneration, and biological regeneration: thermal regeneration uses high temperatures to volatilize and decompose the adsorbed substances, resulting in the highest regeneration efficiency; chemical regeneration utilizes the reaction of reagents with the adsorbed substances to achieve dissolution or decomposition, suitable for the desorption of non-volatile substances; biological regeneration relies on the metabolic decomposition of organic adsorbates by microorganisms, which is low-cost and energy-efficient, but has a long regeneration cycle.

[0003] Regardless of the regeneration method used, the process generates a large amount of harmful waste gas containing dust, sulfides, nitrogen oxides, and volatile organic compounds. If this waste gas is discharged directly without effective treatment, it will not only seriously pollute the air, but also exacerbate environmental problems such as acid rain and smog, and even damage the ozone layer, posing a dual threat to the ecological environment and human health.

[0004] Existing treatment devices for activated carbon regeneration waste gas mostly employ a single filtration structure, which makes it difficult to simultaneously and efficiently remove multiple pollutants such as dust and harmful gases. As a result, the purified waste gas may still not meet emission requirements. Waste gas is prone to local accumulation in the treatment chamber, which not only reduces the utilization rate of the filter components but also easily causes local blockage of filter elements and other components. Therefore, a waste gas treatment device for activated carbon regeneration is provided. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a waste gas treatment device for activated carbon regeneration, which aims to solve the problems mentioned in the background art.

[0006] This utility model provides the following technical solution: a waste gas treatment device for activated carbon regeneration, including a support cylinder, on which a filter treatment component is provided; The filtration assembly includes a processing cylinder disposed at the top of the support cylinder, a processing cover disposed in the middle of the processing cylinder, an inner filter liner disposed in the middle of the processing cover, and a slag outlet disposed at the bottom of the inner filter liner. A turntable is provided in the middle of the inner filter cover, a positioning post is provided on the top of the turntable, and several diversion plates are provided on the outside of the positioning post.

[0007] Optionally, in one possible implementation, the positioning column is shaped like a frustum, and a gathering cover is provided on the top of the processing cover. A processing cavity is formed between the processing cover and the gathering cover. A mounting cylinder is provided on the top of the processing cylinder. A plurality of filter elements are provided inside the mounting cylinder, and the bottom end of each filter element extends into the processing cavity. An air inlet is provided on the outside of the processing cylinder. One end of the air inlet passes through the processing cylinder and the processing cover and extends to the middle of the inner filter cover. An air outlet is provided on the outside of the gathering cover. One end of the air outlet extends to the outside of the processing cylinder. A motor is provided in the middle of the support cylinder. The output end of the motor passes through the processing cover and extends to the bottom of the turntable. The technical effects and advantages of this utility model are as follows: With its dual filtration structure of inner filter cover and filter element, the inner filter cover can first perform preliminary filtration of large particulate dust in the exhaust gas, and the filter element can then perform deep adsorption and removal of sulfides, nitrogen oxides and volatile organic compounds. The dual filtration works synergistically to improve the treatment effect and effectively meet environmental emission requirements. The device is equipped with a frustum-shaped positioning column and a rotatable flow divider. When the motor drives the flow divider to rotate, it can evenly distribute the exhaust gas introduced from the inlet to each area of ​​the inner filter liner, avoiding local accumulation of exhaust gas. Combined with the airflow guiding effect of the gathering hood, the exhaust gas can flow evenly through the filter element, improve the utilization rate of the filter components, reduce local blockage, and extend the continuous operation time of the equipment. The filter liner has a slag outlet at the bottom, which can promptly discharge the solid residue generated during the initial filtration, eliminating the need for frequent disassembly and cleaning and reducing maintenance frequency. At the same time, the improved airflow uniformity also reduces the wear rate of the filter element, indirectly reducing the cost of filter element replacement. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] The waste gas treatment device for activated carbon regeneration disclosed in this embodiment is mainly used for the purification of waste gas containing harmful substances such as dust, sulfides, nitrogen oxides, and volatile organic compounds generated during the activated carbon regeneration process. The device achieves efficient waste gas treatment through multi-layer filtration and airflow optimization structure, avoiding environmental pollution caused by direct emission of harmful gases.

[0016] As attached Figure 1 As shown, the system includes a support cylinder 1, a treatment cylinder 2, a treatment hood 3, an inner filter hood 4, a turntable 6, a positioning column 7, a diverter plate 8, a gathering hood 9, an installation cylinder 10, a filter element 11, an air inlet 12, an air outlet 13, and a motor 14. All components work together to complete the waste gas treatment.

[0017] The support cylinder 1 provides stable support for the device, and the processing cylinder 2 is fixedly installed on the top of the support cylinder 1. The central axes of the two coincide to ensure the overall stability of the device structure.

[0018] As attached Figure 4 As shown, the treatment hood 3 is located in the middle of the treatment cylinder 2, the inner lining filter hood 4 is installed inside the treatment hood 3, and the bottom of the inner lining filter hood 4 is provided with a slag outlet 5 for discharging solid residues generated during the waste gas filtration process.

[0019] The turntable 6 is located in the middle of the inner filter cover 4. The motor 14 is installed in the middle of the support cylinder 1. The output end of the motor 14 passes through the treatment cover 3 and is fixedly connected to the bottom of the turntable 6, which can drive the turntable 6 to rotate around the central axis.

[0020] The positioning post 7 is in the shape of a frustum and is fixed on the top of the turntable 6. Several diverter plates 8 are evenly distributed on the outside of the positioning post 7, and the diverter plates 8 are perpendicular to the surface of the turntable 6 and rotate synchronously with the turntable 6.

[0021] The gathering hood 9 is installed on top of the treatment hood 3, forming a sealed treatment chamber between the treatment hood 3 and the gathering hood 9; the air inlet 12 is located on the outside of the treatment cylinder 2, with one end extending through the treatment cylinder 2 and the treatment hood 3 and then to the middle of the inner filter hood 4, for introducing the waste gas to be treated; the air outlet 13 is located on the outside of the gathering hood 9, with one end extending to the outside of the treatment cylinder 2, for discharging the purified gas.

[0022] As attached Figure 2 As shown, the mounting cylinder 10 is fixed to the top of the treatment cylinder 2, and several filter elements 11 are evenly arranged inside the mounting cylinder 10. The bottom end of each filter element 11 extends into the treatment chamber and communicates with the inside of the treatment chamber to perform deep filtration of the exhaust gas entering the treatment chamber.

[0023] The specific working principle is as follows: the waste gas generated during the activated carbon regeneration process is connected to the air inlet 12 through a pipeline, and the waste gas enters the middle area of ​​the inner lining filter cover 4 through the air inlet 12.

[0024] Start motor 14, which drives turntable 6 to rotate, causing positioning column 7 and flow divider 8 to rotate synchronously. The frustum-shaped positioning column 7, together with the rotating flow divider 8, evenly distributes the concentrated exhaust gas to various areas inside the inner liner filter 4, increasing the contact area between the exhaust gas and the inner wall of the inner liner filter 4. The inner liner filter 4 performs preliminary filtration of large particulate dust and other solid impurities in the exhaust gas, and the solid residue produced by filtration falls naturally through the slag outlet 5.

[0025] After preliminary filtration, the exhaust gas passes through the inner filter liner 4 and enters the treatment chamber formed by the treatment hood 3 and the gathering hood 9. At this time, the structure of the gathering hood 9 can guide the exhaust gas to gather in the middle, so that the exhaust gas flows evenly to the filter element 11 below.

[0026] The exhaust gas entering the treatment chamber flows upward. When it passes through the filter element 11, the filter element 11 deeply adsorbs and filters harmful substances such as sulfides, nitrogen oxides, and volatile organic compounds in the exhaust gas. The purified gas continues to flow upward and is finally discharged from the device through the exhaust port 13, completing the entire exhaust gas treatment process.

[0027] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
