Abstract
Description
Technical Field
[0001] This utility model relates to the field of combustion furnace technology, specifically to a catalytic combustion furnace. Background Technology
[0002] A catalytic combustion furnace is an environmentally friendly device that uses a catalyst to promote the oxidative decomposition of combustible components in organic waste gas at a relatively low temperature. This technology can effectively reduce energy consumption because it typically requires less auxiliary fuel and also reduces the size of the equipment. Catalytic combustion furnaces are suitable for treating waste gas containing combustible gases, vapors, and other toxic and harmful gases, but not suitable for waste gas containing large amounts of dust particles, droplets, or other substances, to prevent clogging of the catalyst bed.
[0003] Because catalytic combustion requires a catalyst for each combustion cycle, and the catalyst needs to be added regularly—neither too much nor too little—the furnace must be shut down each time a catalyst is added. After removing the catalyst, workers, taking protective measures, use a shovel or funnel to add the catalyst from the top of the catalytic combustion furnace. However, due to the potentially high temperatures generated during catalytic combustion and the large size of the furnace, workers must stop the furnace and climb to the top each time to add the catalyst. Improper operation could result in burns. Furthermore, if the catalyst or waste gas inside the catalytic combustion furnace is not properly treated, allowing workers to open the lid directly could pose a safety hazard of inhaling harmful gases. Utility Model Content
[0004] This invention proposes a catalytic combustion furnace, which solves the problem that existing catalytic combustion furnaces require the addition of catalysts at regular intervals, but the high temperature generated inside the furnace and the untreated exhaust gas may burn workers and cause safety hazards.
[0005] The technical solution of this utility model is as follows:
[0006] A catalytic combustion furnace includes a furnace body and a furnace cover. A connecting ring is fixedly connected to the top of the furnace body, and a sliding groove is formed on one side of the connecting ring. The furnace cover is detachably connected to the sliding groove. The furnace also includes:
[0007] Storage bins;
[0008] A sliding mechanism is provided on both sides of the combustion furnace body to move the storage bucket above the combustion furnace body;
[0009] The discharge mechanism is connected to the bottom of the storage tank and is used to discharge the catalyst inside the storage tank into the combustion furnace body.
[0010] A lateral moving mechanism is provided on the sliding mechanism for moving the discharge mechanism to a position above the combustion furnace body, and the storage tank is connected to the lateral moving mechanism for storing catalyst.
[0011] Preferably, the sliding mechanism includes:
[0012] The bottom of the combustion furnace body has four rectangular fixed bases fixedly connected to both parallel sides.
[0013] The slide rail is fixedly connected between every two of the fixed seats.
[0014] Preferably, the discharge mechanism includes:
[0015] The bottom of the storage tank is connected to the discharge pipe;
[0016] A sliding plate, wherein a discharge port is provided on the top of one side of the sliding plate, and one end of the discharge port is connected to the bottom of the discharge pipe;
[0017] A discharge hopper, the top of which is connected to the other end of the discharge port;
[0018] A cover plate, which is hinged to the bottom of the discharge hopper.
[0019] Preferably, the lateral movement mechanism includes:
[0020] Sliding rods, both of which are slidably connected within the slide rail;
[0021] The sliding seat is fixedly connected to the bottom of both sliding rods, and each sliding seat has a sliding opening on the side facing the combustion furnace body, and the sliding plate is slidably connected in the sliding opening.
[0022] Furthermore, the sliding range of the two sliding rods is set between the two fixed seats.
[0023] Furthermore, a limiting plate is fixedly connected to the bottom of one of the sliding seats.
[0024] The working principle and beneficial effects of this utility model are as follows:
[0025] In this invention, when using a catalytic combustion furnace for combustion reaction, the furnace is first shut down to stop operation. The worker pulls the furnace cover to open the top of the furnace. At this time, the lateral moving mechanism slides on the sliding mechanism to the top of the furnace. Then, the discharge mechanism slides to allow the catalyst stored in the storage tank to slide into the furnace through the connecting ring. After sliding, the discharge mechanism and the lateral moving mechanism are returned to their original positions, and the furnace cover is pushed to close it. Compared with the prior art, the worker only needs to open the furnace cover next to the furnace and does not need to climb to the top of the furnace to add catalyst with a shovel, which greatly improves the overall production efficiency and safety and effectively avoids the worker directly inhaling toxic gases inside the furnace.

[0032] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.
[0033] like Figures 1-4As shown, this embodiment proposes a catalytic combustion furnace, including a combustion furnace body 1 and a furnace cover 2. A connecting ring 3 is fixedly connected to the top of the combustion furnace body 1, and a sliding groove 4 is provided on one side of the connecting ring 3. The furnace cover 2 is detachably connected to the sliding groove 4. It also includes a storage tank 5, a sliding mechanism, a discharge mechanism, and a lateral moving mechanism. Sliding mechanisms are provided on both sides of the combustion furnace body 1 for moving the storage tank 5 to be above the combustion furnace body 1. The discharge mechanism is connected to the bottom of the storage tank 5 for discharging the catalyst inside the storage tank 5 into the combustion furnace body 1. The lateral moving mechanism is provided on the sliding mechanism for moving the discharge mechanism to be above the combustion furnace body 1, and the storage tank 5 is connected to the lateral moving mechanism for storing the catalyst.
[0034] In this embodiment, the sliding mechanism includes a fixed seat 101 and a slide rail 102. Four fixed seats 101 are fixedly connected in a rectangular shape on both sides of the bottom of the combustion furnace body 1, and a slide rail 102 is fixedly connected between every two fixed seats 101.
[0035] In this embodiment, the discharge mechanism includes a discharge pipe 201, a sliding plate 202, a discharge bucket 203, and a cover plate 204. The bottom of the storage bucket 5 is connected to the discharge pipe 201. A discharge port is opened on the top of one side of the sliding plate 202, and one end of the discharge port is connected to the bottom of the discharge pipe 201. The top of the discharge bucket 203 is connected to the other end of the discharge port. The cover plate 204 is hinged to the bottom of the discharge bucket 203. The top of the sliding plate 202 has a discharge port on only one side. The purpose is that when the sliding plate 202 moves towards one end of the combustion furnace body 1, the catalyst in the discharge pipe 201 will be covered by the end of the sliding plate 202 without a discharge port, so that the catalyst inside the storage bucket 5 will not fall out.
[0036] In this embodiment, the lateral movement mechanism includes sliding rods 301 and sliding seats 302. Both sliding rods 301 are slidably connected within the slide rail 102, and the bottom of each sliding rod 301 is fixedly connected to the sliding seat 302. Each sliding seat 302 has a sliding opening 303 on the side facing the combustion furnace body 1, and the sliding plate 202 is slidably connected within the sliding opening 303. The sliding range of the two sliding rods 301 is set between the two fixed seats 101, limiting the sliding range of the sliding rods 301. To prevent the catalyst from sliding outwards and causing equipment malfunction, a limiting plate 6 is fixedly connected to the bottom of one of the sliding seats 302. The purpose of this is to fix the cover plate 204, which is hinged to the bottom of the discharge barrel 203, so as to prevent the catalyst from leaking out. When the sliding plate 202 slides outwards beyond the limiting plate 6, the cover plate 204 will automatically open downwards. When the sliding plate 202 is slid back to its original position, the limiting plate 6 will press against the bottom of the cover plate 204, moving the cover plate 204 upwards to cover the bottom of the discharge barrel 203, so that the catalyst inside the discharge barrel 203 will not overflow or slide outwards.
[0037] In summary, the working principle of this catalytic combustion furnace is as follows: When using the catalytic combustion furnace for catalytic reaction, the furnace body 1 is not started initially. At this time, the storage tank 5 containing the catalyst is placed at one end of the slide rail 102. The worker pulls the furnace cover 2 outward to open the furnace body 1, making the furnace body 1 open. Then, by sliding the sliding rod 301 to an oblique position above the furnace body 1, the storage tank 5 is also positioned above the discharge tank 203. Since the storage tank 5 is connected to the discharge pipe 201 and the discharge tank 203, the catalyst stored in the storage tank 5 will move into the discharge tank 203. When the catalyst fills one discharge tank 203, it is ready to wait for the next catalyst addition. Then, the sliding plate 202 is slid towards the furnace body 1. When the sliding plate 202 moves the discharge tank 203 towards the furnace body... As the material moves in the direction of 1 and the discharge bucket 203 moves out of the limiting plate 6, since the cover plate 204 is hinged to the bottom of the discharge bucket 203 and does not fix the cover plate 204 and the discharge bucket 203 together, when the limiting plate 6 is not under the cover plate 204, the cover plate 204 will automatically open downward through the hinge arc. At this time, the discharge bucket 203 is located directly above the combustion furnace body 1. When the cover plate 204 opens, the catalyst inside the discharge bucket 203 will slide into the combustion furnace body 1. After the catalyst enters the combustion furnace body 1, the sliding plate 202 is retracted. At this time, the catalyst in the storage bucket 5 and the discharge pipe 201 will fall into the discharge bucket 203 again, waiting for the next discharge. The sliding rod 301 is moved back to its original position. At the same time, the worker pushes the furnace cover 2 to close, so that the combustion furnace body 1 forms a sealed space.
[0038] 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.
