Abstract
Description
Technical Field
[0001] This application relates to the field of industrial waste gas treatment technology, specifically to an automatic feeding device for an industrial waste gas treatment system. Background Technology
[0002] In industrial waste gas treatment systems, activated carbon adsorption is widely used due to its high efficiency and economy. However, with increasingly stringent environmental standards, the system needs to frequently replace saturated activated carbon, with an annual replacement volume of up to tens of tons. Currently, mainstream waste gas treatment systems consume a high amount of activated carbon daily.
[0003] However, when manually replacing activated carbon, the adsorption device needs to be opened for filling. When the adsorption device is opened, the volatile organic compounds adsorbed in the activated carbon will directly escape into the environment, resulting in fugitive emissions. If the concentration of volatile organic compounds in the exhaust gas is high, the leakage may far exceed the emission standards, causing regional air pollution. When replacing activated carbon, operators may be exposed to a high concentration of volatile organic compounds. Long-term exposure can easily cause health problems such as headaches, nausea, and respiratory irritation, and may even increase the risk of cancer. Utility Model Content
[0004] To address the shortcomings of existing technologies, this application provides an automatic feeding device for an industrial waste gas treatment system. This device offers advantages such as improving the operating environment for workers. It solves the problems of existing manual activated carbon replacement methods, which require opening the adsorption device for filling. When the adsorption device is opened, the volatile organic compounds adsorbed in the activated carbon will directly escape into the environment, resulting in fugitive emissions. If the concentration of volatile organic compounds in the waste gas is high, the leakage may far exceed the emission standards, causing regional air pollution. Operators may also be exposed to high concentrations of volatile organic compounds when replacing activated carbon, and long-term exposure may cause health problems such as headaches, nausea, and respiratory irritation, and may even increase the risk of cancer.
[0005] To achieve the above objectives, this application provides the following technical solution: an automatic feeding device for an industrial waste gas treatment system, comprising a housing and a lifting pipe, wherein a feed inlet is provided on one side of the upper end of the housing, a fixing frame is fixedly connected to one side of the housing, a first spiral rod is rotatably connected inside the lifting pipe, a feed hopper is fixedly connected to the bottom end of the lifting pipe, a cover plate is rotatably connected to one side of the upper end of the feed hopper via a hinge, and a feed pipe is fixedly connected to the upper end of the outer wall of the lifting pipe.
[0006] With the above solution, when it is necessary to replace the activated carbon or other adsorbent materials inside the chamber, there is no need to open the cover, reducing the release of volatile organic compounds (VOCs) from the saturated activated carbon or other adsorbent materials inside the chamber. Instead, the activated carbon or other adsorbent materials are added to the feed hopper, and the material is lifted to the feed pipe by the rotation of the first screw inside the lifting pipe before being added to the chamber. This eliminates the need to directly open the chamber when adding activated carbon or other adsorbent materials, reducing the release of VOCs during the filling process and lowering the risk of fugitive VOC emissions. By reducing the direct opening of the chamber, the risk of operators being exposed to VOCs is reduced, thereby lowering the probability of health problems.
[0007] Furthermore, a partition is fixedly connected inside the box, an air distribution plate is fixedly connected to one side inside the box, two slide rails arranged in a mirror image are fixedly connected to both sides inside the box, a mesh is fixedly connected to the side of the box away from the air distribution plate, an air outlet pipe is fixedly connected to the end of the mesh that penetrates the box, and an air inlet is opened at the end of the box away from the air outlet pipe.
[0008] The above solution ensures that the exhaust gas is evenly distributed after entering by a uniform air distribution plate fixed to one side of the box, avoiding uneven adsorption caused by local airflow being too fast or too slow, improving the utilization rate and treatment efficiency of adsorption materials such as activated carbon, and the partition plate rationally divides the internal space of the box to optimize the airflow path. The mesh can intercept the escaped activated carbon particles to ensure the purity of the purified gas.
[0009] Furthermore, filter elements are slidably arranged between each of the four slide rails in pairs.
[0010] The above scheme allows for the rapid installation and removal of filter elements by symmetrically arranged slide rails on both sides, reducing maintenance downtime and simplifying manual operation. Filter elements between each set of slide rails can slide out independently for replacement. As the first line of defense, the filter elements intercept large particles, dust, oil mist, and other impurities in the exhaust gas, preventing them from directly entering the activated carbon layer and extending the service life of the activated carbon. This also reduces pore blockage and lowers the replacement frequency.
[0011] Furthermore, the upper end of the housing is rotatably connected by two sealing plates arranged in a mirror image via hinges.
[0012] With the above solution, the sealing plate can be quickly opened via a hinge design, which is suitable for filter element replacement. After opening the sealing plate, the operator can directly pull out the filter element for replacement.
[0013] Furthermore, the bottom of the housing is fixedly connected to four legs arranged in a rectangular array.
[0014] With the above scheme, the four legs are distributed in a mirror image, forming a stable four-corner support structure to support the overall weight of the box.
[0015] Furthermore, a discharge hopper is fixedly connected to the bottom of the box, a discharge pipe is fixedly connected to the bottom of the discharge hopper, a second spiral rod is rotatably connected inside the discharge pipe, and a discharge pipe is fixedly connected to one side of the bottom of the discharge pipe.
[0016] Through the above scheme, the second screw continuously conveys the adsorbed saturated activated carbon to the discharge pipe by rotating, avoiding the accumulation of material in the discharge hopper. The discharge hopper and discharge pipe are closed structures, which, together with the screw's sealed conveying, prevent dust leakage.
[0017] Furthermore, the lifting tube is fixedly installed inside the fixing frame.
[0018] With the above method, the lifting pipe is fixed to one side of the box body by a fixing bracket.
[0019] Furthermore, the end of the feed pipe away from the riser pipe passes through the feed inlet and extends into the interior of the housing.
[0020] With the above solution, the feed pipe extends into the inside of the chamber, ensuring that the adsorbent material enters the treatment area directly.
[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects:
[0022] This industrial waste gas treatment system uses an automatic feeding device. When it is necessary to replace the activated carbon or other adsorbent materials inside the chamber, there is no need to open the cover. This reduces the release of volatile organic compounds (VOCs) from the saturated activated carbon or other adsorbent materials inside the chamber. The activated carbon or other adsorbent materials are added into the feed hopper, and the material is lifted to the feed pipe by the rotation of the first screw inside the lifting pipe, and then added into the chamber. When adding activated carbon or other adsorbent materials, there is no need to directly open the chamber, which reduces the release of VOCs during the filling process and lowers the risk of fugitive emissions of VOCs. Since the direct opening of the chamber is reduced, the risk of operators being exposed to VOCs is reduced, thereby reducing the probability of health problems. Attached Figure Description

[0031] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0032] Please see Figure 1 , Figure 2 and Figure 3 An automatic feeding device for an industrial waste gas treatment system in this embodiment includes a housing 1 and a lifting pipe 4. A feed inlet 2 is provided on one side of the upper end of the housing 1, and a fixing frame 3 is fixedly connected to one side of the housing 1. A first screw rod 5 is rotatably connected inside the lifting pipe 4. The material is lifted to the feed pipe 8 by the rotation of the first screw rod 5 inside the lifting pipe 4 and then added into the housing 1. When adding adsorbent materials such as activated carbon, it is not necessary to directly open the housing 1, which reduces the release of volatile organic compounds during the filling process and reduces the risk of fugitive emissions of volatile organic compounds. A feed hopper 6 is fixedly connected to the bottom end of the lifting pipe 4, and a cover plate 7 is rotatably connected to one side of the upper end of the feed hopper 6 via a hinge. A feed pipe 8 is fixedly connected to the upper end of the outer wall of the lifting pipe 4. The feed pipe 8 is used to put adsorbent materials such as activated carbon into the housing 1.
[0033] Please see Figure 4 and Figure 5A partition 9 is fixedly connected inside the housing 1. A uniform air distribution plate 10 is fixedly connected to one side of the housing 1. The uniform air distribution plate 10 ensures that the exhaust gas is evenly distributed after entering the housing 1, avoiding uneven adsorption caused by local airflow being too fast or too slow, and improving the utilization rate and treatment efficiency of adsorption materials such as activated carbon. Two slide rails 11 are fixedly connected to both sides of the housing 1 in a mirror arrangement. A mesh 12 is fixedly connected to the side of the housing 1 away from the uniform air distribution plate 10. An air outlet pipe 13 is fixedly connected to the end of the mesh 12 that penetrates the housing 1. An air inlet 14 is opened at the end of the housing 1 away from the air outlet pipe 13. The partition 9 divides the housing into sections. The internal space of the body 1 is rationally divided and the airflow path is optimized. The mesh 12 can intercept the escaped activated carbon particles to ensure the purity of the purified gas. The four slide rails 11 are all equipped with filter elements 15 in pairs. The slide rails 11 arranged symmetrically on both sides allow the filter elements 15 to be quickly installed and removed, reducing maintenance downtime and reducing the difficulty of manual operation. The filter elements 15 between each set of slide rails 11 can be slid out independently for independent replacement. As the first line of defense, the filter elements 15 intercept large particles, dust, oil mist and other impurities in the exhaust gas, preventing them from directly entering the activated carbon layer, extending the service life of activated carbon, reducing the clogging of activated carbon pores and reducing the replacement frequency.
[0034] Please see Figure 2 , Figure 5 and Figure 6 The upper part of the housing 1 is connected by a hinge to two mirror-shaped sealing plates 16. The sealing plates 16 can be quickly opened via the hinge design, which is suitable for replacing the filter element 15. After opening the sealing plates 16, the operator can directly pull out the filter element 15 for replacement. The bottom of the housing 1 is fixedly connected to four support legs 17 arranged in a rectangular array. The four support legs 17 are mirror-shaped and form a stable four-corner support structure to support the overall weight of the housing 1. The bottom of the housing 1 is fixedly connected to a discharge hopper 18, and the bottom of the discharge hopper 18 is fixedly connected to a discharge pipe 19. The discharge pipe 19 rotates internally to connect to a second... The screw rod 20 and the discharge pipe 19 are fixedly connected to the discharge pipe 21 on one side of the bottom. The second screw rod 20 continuously conveys the adsorbed saturated activated carbon to the discharge pipe 21 by rotating, avoiding the accumulation of material in the discharge hopper 18. The discharge hopper 18 and the discharge pipe 19 are closed structures, which, together with the screw rod, prevent dust leakage. The lifting pipe 4 is fixedly installed inside the fixing frame 3. The lifting pipe 4 is fixed to one side of the box 1 by the fixing frame 3. The end of the feed pipe 8 away from the lifting pipe 4 passes through the feed port 2 and extends into the box 1. The extension of the feed pipe 8 into the box 1 can ensure that the adsorbent material directly enters the treatment area.
[0035] In this embodiment, the automatic feeding device of the industrial waste gas treatment system eliminates the need to open the cover plate 7 when the activated carbon or other adsorbent materials inside the housing 1 need to be replaced. This reduces the release of volatile organic compounds (VOCs) from the saturated activated carbon or other adsorbent materials inside the housing 1. Instead, the activated carbon or other adsorbent materials are added to the feed hopper 6 and then lifted to the feed pipe 8 by the rotation of the first screw rod 5 inside the lifting pipe 4 before being added to the housing 1. This eliminates the need to directly open the housing 1 when adding the activated carbon or other adsorbent materials, reducing the release of VOCs during the filling process and lowering the risk of fugitive VOC emissions. Furthermore, by reducing the direct opening of the housing 1, the risk of operators being exposed to VOCs is reduced, thereby lowering the probability of health problems.
[0036] It should be noted that filter element 15 is a PP filter element 15, used for exhaust gas pretreatment to remove dust and oil mist, reduce pore clogging of adsorption materials such as activated carbon, and extend service life.
[0037] The working principle of the above embodiments is as follows:
[0038] When replacing the activated carbon inside the housing 1, the saturated activated carbon inside the housing 1 is first transported to the discharge pipe 21 by the guide of the discharge hopper 18 and the rotation of the second screw 20 for discharge. The discharge process is completely enclosed to prevent dust leakage and reduce the emission of volatile organic compounds. When feeding, the operator opens the cover plate 7 and pours the activated carbon and other adsorbent materials into the feed hopper 6. The first screw 5 rotates to lift the material from the feed hopper 6 to the feed pipe 8, and then directly delivers it into the housing 1 through the feed inlet 2. The entire operation is enclosed to prevent the unorganized emission of volatile organic compounds. Compared with traditional manual filling, this reduces the need for opening the housing 1. The number of start-up cycles is reduced, minimizing the risk of volatile organic compound (VOC) emissions and minimizing operator exposure to high concentrations of VOCs. Exhaust gas enters the housing 1 through the air inlet 14 and is evenly distributed by the air distribution plate 10, preventing uneven adsorption caused by excessively fast local airflow. The PP material filter element 15 serves as the first line of defense, intercepting large particles such as dust and oil mist in the exhaust gas, protecting the activated carbon layer, and extending its service life. Symmetrical slide rails 11 on both sides allow for quick sliding installation and removal of the filter element 15. The pre-treated exhaust gas passes through the partition 9, making full contact with the activated carbon to adsorb VOCs. The purified gas is then filtered by the mesh 12 and discharged through the exhaust pipe 13.
