Abstract
Description
Technical Field
[0001] This utility model relates to the field of chemical acid mist exhaust gas treatment technology, and in particular to an acid mist exhaust gas treatment system for the chemical industry. Background Technology
[0002] Chemical acid mist is a gaseous pollutant containing acidic substances generated during chemical production, posing significant harm to the environment and human health. Its main components include sulfuric acid mist, hydrochloric acid mist, and nitric acid mist, and it may also contain hydrofluoric acid and phosphoric acid mist. Sources include acid mist generated during pickling processes when acid reacts with metals, and during the manufacturing processes of chemical products such as phosphate fertilizer production.
[0003] Chemical acid mist waste gas needs to be treated before it can be discharged, therefore a fixed bed adsorber is required for its treatment. Publication number CN219399541U discloses a horizontal square fixed bed adsorber with quick adsorbent replacement. It is composed of an adsorber body, a gas inlet, a gas outlet, an adsorbent loading port, an adsorbent loading box side plate, an adsorbent layer, an adsorbent discharge port, a manual slide valve, and a blind flange. The adsorber body is made of metal and has a horizontal square double-cone head structure. The conical heads of the adsorber body guide the airflow, ensuring a uniform gas flow field inside the adsorber body and reducing gas resistance drop. One or more adsorbent loading boxes are installed inside the adsorber body. The bottom is equipped with an adsorbent discharge port, and both the adsorbent loading port and the adsorbent discharge port are equipped with blind flanges or manual gate valves. By opening and closing the blind flanges or manual gate valves, the purpose of preventing waste gas from short-circuiting and quickly replacing the adsorbent can be achieved. Although the prior art achieves quick replacement of the adsorbent, it does not change the connection method between the inlet and outlet ports and the inlet and outlet pipes. It still uses flange connections. Although this method is relatively simple to operate, it is time-consuming and labor-intensive, which affects work efficiency. Moreover, the flange connection does not have a sealing mechanism. If the sealing is insufficient, the waste gas will escape to the outside and cause environmental pollution. Therefore, this application proposes an acid mist waste gas treatment system for the chemical industry to meet the needs. Utility Model Content
[0004] In order to overcome the shortcomings of existing devices, such as the time-consuming and labor-intensive connection between the air inlet and outlet and the air inlet and outlet pipes, and the fact that insufficient sealing can lead to exhaust gas leakage, this utility model provides an acid mist exhaust gas treatment system for the chemical industry.
[0005] The technical implementation scheme of this utility model is as follows: an acid mist exhaust gas treatment system for the chemical industry, including an adsorber, with inlet and outlet ports at both ends of the adsorber, an inlet and outlet pipe provided on the outside of the inlet and outlet ports, a first mounting base fixedly connected to the outer periphery of the inlet and outlet ports, and a second mounting base fixedly connected to the outer periphery of the inlet and outlet pipes, and an installation component and a sealing component provided at the connection between the first mounting base and the second mounting base.
[0006] Optionally, the mounting assembly includes a mounting groove, a mounting block, a mounting hole, a first connecting groove, and a mounting rod. The mounting groove is formed on the side surface of the second mounting base near the first mounting base. The mounting block is fixedly connected to the side surface of the first mounting base near the second mounting base and is adapted to the size of the mounting groove. The mounting hole passes through the mounting block. The first connecting groove is formed inside the second mounting base and communicates with the mounting groove. The mounting rod is slidably connected to the first connecting groove and is adapted to the size of the mounting hole.
[0007] Optionally, the mounting assembly further includes a cavity, a rotating ring, and a first connecting block. The cavity is annular and is located inside the second mounting base and communicates with the first connecting groove. The rotating ring is rotatably connected to the cavity. The first connecting block is slidably connected to the first connecting groove and its two ends are respectively fixedly connected to the mounting rod and the rotating ring.
[0008] Optionally, the mounting assembly further includes a slide groove, a second connecting groove, a slider, a second connecting block, and a spring. The slide groove is formed on the surface of the second mounting base away from the first mounting base. The second connecting groove is formed on the inner wall of the top of the slide groove and communicates with the cavity. The slider is slidably connected to the slide groove. The second connecting block is slidably connected to the second connecting groove and its two ends are respectively fixedly connected to the slider and the rotating ring. The spring is installed inside the slide groove and its two ends are respectively fixedly connected to one side of the slider and one side of the inner wall of the slide groove.
[0009] Optionally, the sealing assembly includes a sealing groove, an annular groove, and a sealing ring. The sealing groove is formed on the side surface of the first mounting base near the second mounting base, the annular groove is formed on the side surface of the second mounting base near the first mounting base, the sealing ring is installed inside the annular groove and, after expansion, adapts to the size of the sealing groove, and the sealing ring is made of rubber and is hollow inside.
[0010] Optionally, the sealing assembly further includes an air chamber, a connecting hole, a piston, and a connecting rod. The air chamber is located inside the second mounting base and communicates with one end of the slide groove. The connecting hole is located on the inner wall of one end of the air chamber and communicates with the sealing ring. The piston is slidably connected to the air chamber and is sized to match it. The connecting rod is movably connected to the air chamber and its two ends are respectively fixedly connected to the slider and the piston.
[0011] This utility model has the following advantages:
[0012] 1. This utility model features an installation assembly. A sliding block along a groove compresses a spring. During this process, a second connecting block drives a rotating ring to move synchronously within the cavity with the sliding block. The rotating ring, in turn, drives a mounting rod to move synchronously within the first connecting groove via the first connecting block until it is submerged. Then, the first and second mounting seats are tightly joined together, inserting the mounting block into the mounting groove. At this point, the sliding block is released, the spring rebounds, and the sliding block drives the rotating ring to move in the opposite direction. The rotating ring then drives the mounting rod to move in the opposite direction. When the mounting rod is inserted into the mounting hole, the mounting block is fixed in the mounting groove, thus completing the connection between the first and second mounting seats. This design simplifies and speeds up the connection between the air inlet / outlet pipe and the air inlet / outlet port, thereby improving work efficiency.
[0013] 2. This utility model incorporates a sealing component. During the process of the slider compressing the spring, the connecting rod drives the piston to move synchronously along the air chamber with the slider, drawing air from the sealing ring into the air chamber through the connecting hole. When the sealing ring shrinks to the point of being submerged in the annular groove, the first and second mounting seats can be connected. After the connection is completed, the spring rebounds and drives the slider to move in the opposite direction. At this time, the connecting rod drives the piston to move in the opposite direction along the air chamber with the slider, sending air from the air chamber into the sealing ring through the connecting hole. When the sealing ring expands to fit tightly against the sealing groove, the connection between the first and second mounting seats is sealed. This design effectively prevents insufficient sealing at the connection point from causing exhaust gas to escape into the outside world and pollute the environment. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of the present invention more clearly apparent, the present invention will be further described in detail below with reference to the accompanying drawings. It is hereby stated that any directional terms such as "up," "down," "left," "right," "front," "back," "inside," and "outside" that appear or will appear in this document are based solely on the accompanying drawings and are not intended to limit the present invention.
[0022] A system for treating acid mist exhaust gas in the chemical industry includes an adsorber 1. Both ends of the adsorber 1 are provided with inlet and outlet ports 2. An inlet and outlet pipe 3 is provided on the outside of the inlet and outlet ports 2. A first mounting base 4 is fixedly connected to the outer periphery of the inlet and outlet ports 2. A second mounting base 5 is fixedly connected to the outer periphery of the inlet and outlet pipe 3. An installation component 6 and a sealing component 7 are provided at the connection between the first mounting base 4 and the second mounting base 5.
[0023] It should be noted that the installation component 6 makes the connection between the air inlet / outlet pipe 3 and the air inlet / outlet port 2 simpler and faster, thereby improving work efficiency. The sealing component 7 can seal the connection between the air inlet / outlet pipe 3 and the air inlet / outlet port 2, effectively preventing exhaust gas from escaping to the outside world and causing pollution to the environment.
[0024] like Figure 2 , Figure 3 and Figure 4 As shown, the mounting component 6 includes a mounting groove 61, a mounting block 62, a mounting hole 63, a first connecting groove 64, and a mounting rod 65. The mounting groove 61 is formed on the side surface of the second mounting base 5 near the first mounting base 4. The mounting block 62 is fixedly connected to the side surface of the first mounting base 4 near the second mounting base 5 and is adapted to the size of the mounting groove 61. The mounting hole 63 passes through the mounting block 62. The first connecting groove 64 is formed inside the second mounting base 5 and communicates with the mounting groove 61. The mounting rod 65 is slidably connected to the first connecting groove 64 and is adapted to the size of the mounting hole 63.
[0025] It should be noted that the mounting block 62 is placed in the mounting groove 61, and then the mounting rod 65 is inserted into the mounting hole 63 to fix the mounting block 62 in the mounting groove 61. At this time, the connection between the first mounting seat 4 and the second mounting seat 5 can be completed.
[0026] like Figure 3 and Figure 4 As shown, the mounting assembly 6 also includes a cavity 66, a rotating ring 67, and a first connecting block 68. The cavity 66 is annular and is opened inside the second mounting base 5 and communicates with the first connecting groove 64. The rotating ring 67 is rotatably connected to the cavity 66. The first connecting block 68 is slidably connected to the first connecting groove 64 and its two ends are respectively fixedly connected to the mounting rod 65 and the rotating ring 67.
[0027] It should be noted that rotating the rotating ring 67 along the cavity 66 can drive the mounting rod 65 to move synchronously through the first connecting block 68, thereby inserting the mounting rod 65 into the mounting hole 63 or removing the mounting rod 65 from the mounting hole 63.
[0028] like Figure 5 and Figure 6 As shown, the mounting assembly 6 also includes a slide groove 69, a second connecting groove 610, a slider 611, a second connecting block 612, and a spring 613. The slide groove 69 is formed on the surface of the second mounting base 5 away from the first mounting base 4. The second connecting groove 610 is formed on the inner wall of the top of the slide groove 69 and communicates with the cavity 66. The slider 611 is slidably connected to the slide groove 69. The second connecting block 612 is slidably connected to the second connecting groove 610 and its two ends are respectively fixedly connected to the slider 611 and the rotating ring 67. The spring 613 is installed inside the slide groove 69 and its two ends are respectively fixedly connected to one side of the slider 611 and one side of the inner wall of the slide groove 69.
[0029] It should be noted that when the slider 611 is slid along the groove 69 to compress the spring 613, the second connecting block 612 will drive the rotating ring 67 to move synchronously with the slider 611. When the slider 611 is released, the spring 613 will rebound and drive the rotating ring 67 to move in the opposite direction through the slider 611.
[0030] like Figure 2 and Figure 3 As shown, the sealing assembly 7 includes a sealing groove 71, an annular groove 72, and a sealing ring 73. The sealing groove 71 is formed on the side surface of the first mounting base 4 near the second mounting base 5. The annular groove 72 is formed on the side surface of the second mounting base 5 near the first mounting base 4. The sealing ring 73 is installed inside the annular groove 72 and, after expansion, matches the size of the sealing groove 71. The sealing ring 73 is made of rubber and is hollow inside.
[0031] It should be noted that after the connection between the first mounting base 4 and the second mounting base 5 is completed, air is injected into the sealing ring 73 to make it expand and fit tightly against the sealing groove 71. At this time, the connection between the first mounting base 4 and the second mounting base 5 can be sealed.
[0032] like Figure 5 and Figure 6As shown, the sealing assembly 7 also includes an air chamber 74, a connecting hole 75, a piston 76, and a connecting rod 77. The air chamber 74 is located inside the second mounting base 5 and is connected to one end of the slide groove 69. The connecting hole 75 is located on the inner wall of one end of the air chamber 74 and is connected to the sealing ring 73. The piston 76 is slidably connected to the air chamber 74 and is sized to match it. The connecting rod 77 is movably connected to the air chamber 74 and its two ends are fixedly connected to the slider 611 and the piston 76, respectively.
[0033] It should be noted that by sliding the piston 76 along the air chamber 74, air in the air chamber 74 can be sent to the sealing ring 73 through the connecting hole 75, or air in the sealing ring 73 can be drawn into the air chamber 74.
[0034] In specific application scenarios, when connecting the air inlet / outlet pipe 3 to the air inlet / outlet port 2, firstly, slide the slider 611 along the slide groove 69 to compress the spring 613. During this process, the second connecting block 612 drives the rotating ring 67 to move synchronously with the slider 611 within the cavity 66. The rotating ring 67 then drives the mounting rod 65 to move synchronously within the first connecting groove 64 via the first connecting block 68 until it is submerged in the first connecting groove 64. Simultaneously, the connecting rod 77 drives the piston 76 to move synchronously with the slider 611 along the air chamber 74, drawing air from the sealing ring 73 into the air chamber 74 through the connecting hole 75. When the sealing ring 73 shrinks to be submerged in the annular groove 72, the first mounting seat 4 and the second mounting seat 5 are tightly fitted together, causing the mounting block 62 to be inserted into the mounting groove 61. Then, the slider 611 is released, the spring 613 rebounds, and the rotating ring 67 moves in the opposite direction via the slider 611. The rotating ring 67 drives the mounting rod 65 to move in the opposite direction. When the mounting rod 65 is inserted into the mounting hole 63, the mounting block 62 can be fixed in the mounting groove 61, thus completing the connection between the first mounting seat 4 and the second mounting seat 5. At the same time, the connecting rod 77 drives the piston 76 to move in the opposite direction along the air chamber 74 with the slider 611, and sends the air in the air chamber 74 to the sealing ring 73 through the connecting hole 75. When the sealing ring 73 expands to fit tightly with the sealing groove 71, the connection between the first mounting seat 4 and the second mounting seat 5 can be sealed. When it is necessary to remove the air inlet and outlet pipe 3 from the air inlet and outlet port 2, the slider 611 is slid along the slide groove 69 again to compress the spring 613. When the mounting rod 65 is removed from the mounting hole 63 and the sealing ring 73 shrinks to be submerged in the annular groove 72, the mounting block 62 is removed from the mounting groove 61 to release the connection between the first mounting seat 4 and the second mounting seat 5.
[0035] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
