Description

Technical Field

[0001] This invention relates to the field of alloy waste gas recovery and treatment technology, and in particular to an alloy smelting waste gas recovery and treatment device and method. Background Technology

[0002] Alloy smelting waste gas contains acidic components and requires deacidification treatment. Current technologies typically involve cooling the waste gas before sending it to a treatment tank, adding an alkaline liquid (such as NaOH solution) to neutralize and deacidify it, and then discharging it into purification equipment (such as activated carbon adsorption). However, this approach has drawbacks:

[0003] Purification equipment is prone to clogging (mainly on the air inlet surface of the activated carbon purification plate): After acid removal, the gas carrying particulate matter accumulates, causing the purification surface to become clogged. In order to improve purification efficiency, multiple purification plates are arranged in the same position, and the gas between each purification plate unit is interconnected to form a purification channel. However, when the purification surface of one purification plate unit becomes clogged, it will affect the normal use of other purification plate units. When shutting down the exhaust gas source equipment and cleaning the purification plates, it is necessary to open the purification chamber and remove the purification plates one by one, making cleaning difficult. Summary of the Invention

[0004] To address the above problems, the present invention provides the following technical solution:

[0005] An alloy smelting waste gas recovery and treatment device includes a purification chamber, an activated carbon purification assembly, an anti-clogging mechanism, and a reciprocating mechanism. The activated carbon purification assembly includes a first purification plate and a second purification plate disposed within the purification chamber but at different angular positions. The anti-clogging mechanism includes a first cleaning seat disposed on the purification surface of the first purification plate and a second cleaning seat disposed on the purification surface of the second purification plate. The transmission part of the reciprocating mechanism is disposed opposite to each other within the purification chamber and drives the first cleaning seat to move linearly along the purification surface of the first purification plate. The second cleaning seat is disposed opposite to the linear path of the first cleaning seat and moves linearly along the purification surface of the second purification plate when it is crushed by the first cleaning seat. There are several second purification plates, with a purification zone a between two second purification plates and the first purification plate. The purification zone of the first purification plate is disposed above the last purification zone a. When the second cleaning seat moves in the reverse direction after being crushed by the first cleaning seat, it triggers the vibration of the first purification plate.

[0006] As a further preferred option, the purification chamber is a horizontal chamber with an air inlet at the left end and an air outlet at the right end, and the first purification plate is horizontally arranged inside the purification chamber.

[0007] As a further preferred embodiment, the purification chamber is equipped with a baffle plate. The purification area of ​​the first purification plate is only located above the last second purification plate. The purification surfaces of the first and second purification plates face the baffle plate. An opening is provided at the connection between the bottom of the second purification plate and the baffle plate. An exhaust port is provided at the bottom left side of the interior of the purification chamber. The left end of the baffle plate is connected to the exhaust port.

[0008] As a further preferred embodiment, the second purification plate stands upright on the bottom side of the first purification plate, and the bottom end of the second purification plate is connected to a guide plate. The second cleaning seat has a buckling cavity opening from the bottom upwards, which is fastened to the top of the first purification plate. The buckling cavity is provided with a spring seat that is elastically connected to the top of the second purification plate. Under the elastic support of the top of the spring seat, the top of the second cleaning seat elastically abuts against the bottom purification surface of the first purification plate. The bottom of the second cleaning seat is connected to a scraper, which contacts the purification surface of the second purification plate.

[0009] As a further preferred embodiment, the bottom end of the second cleaning seat is provided with a lifting rod, which extends downward from the outer wall of the end of the second purification plate to near the bottom end of the second purification plate. The scraper consists of several pieces connected from top to bottom on the lifting rod, with a gap between each pair of adjacent scrapers.

[0010] As a further preferred embodiment, two purification chambers are formed between the second purification plate, the first purification plate, and the guide plate. The two purification chambers include a first purification chamber that is disposed opposite to the left side of the second purification plate and close to the air inlet, and a second purification chamber that is disposed opposite to the right side of the second purification plate and close to the air outlet. The lengths of the two ends of the first purification plate involve the first purification chamber and the second purification chamber.

[0011] As a further preferred embodiment, the first purification panel is provided with a frame around its perimeter. A first hanging plate is installed from the top downwards on the left side inside the purification chamber, and a second hanging plate is installed from the bottom upwards on the right side inside the chamber. The left end of the frame is connected to the first hanging plate, and the right end of the frame is connected to the second hanging plate. The first purification panel is fitted inside the frame, and the perimeter of the first purification panel is elastically connected to the second hanging plate and the first hanging plate by a spring. The bottom purification surface of the first purification panel protrudes from the bottom of the frame and contacts the first cleaning seat.

[0012] As a further preferred embodiment, the first cleaning seat is provided with arc-shaped driving parts on the left and right sides, the second cleaning seat is provided with arc-shaped driven parts on the left and right sides that form a rolling relationship with the arc-shaped driving parts, and the bottom of the first cleaning seat is provided with a transition wheel.

[0013] As a further preferred embodiment, the first cleaning seat and scraper are multi-functional cleaning structures, with a flushing pipe inside. One end of the flushing pipe extends to the outer end of the first cleaning seat and scraper and is connected to an external high-pressure water source via a hose.

[0014] This invention provides a method for recovering and treating alloy smelting waste gas, using the alloy smelting waste gas recovery and treatment device described above, including the following steps:

[0015] a. Waste gas cooling: The alloy smelting waste gas is cooled to 40-60℃ through a cooling unit;

[0016] b. Deacidification treatment: Cooling exhaust gas is sent into the purification chamber through the air inlet, and after being purified by the first purification plate and the second purification plate in the first purification chamber and the second purification chamber, it is discharged through the air outlet; the treated gas is discharged through the treated gas outlet.

[0017] c. Purification treatment: The equipment that provides alloy smelting waste gas is shut down. At the same time, the first cleaning seat is driven by the reciprocating mechanism to clean the blockage on the surface of the first purification plate. The second cleaning seat is also driven by the first cleaning seat to clean the blockage on the surface of the second purification plate, so as to ensure that the first and second purification chambers will operate normally the next time they are used.

[0018] The advantages of this invention compared to the prior art are:

[0019] 1. Functionally, multiple second purification plates form multiple purification zones a on the air inlet side of the first purification plate. This allows the exhaust gas to be differentiated by multiple purification zones a before purification, increasing the purification area and reducing the workload of the first purification plate per unit area. The exhaust gas undergoes secondary purification after passing through multiple units, improving purification quality and extending the clogging time of each purification surface, thus reducing cleaning frequency. The reciprocating mechanism drives the first cleaning seat to move linearly along the purification surface of the first purification plate, treating dust or sticky substances adhering to its surface and ensuring effective purification. As the first cleaning seat moves linearly, it also sequentially pushes each second cleaning seat, causing each second cleaning seat to move linearly along its corresponding second purification plate. Since the second cleaning seats are located on the purification surface of the second purification plate, their linear movement treats dust or sticky substances adhering to their surfaces, ensuring effective purification.

[0020] 2. Structurally, when the first cleaning seat cleans the surface of the first purification plate, it also drives the second cleaning seat to clean the surface of the second purification plate through a rolling relationship, eliminating the need for a power component. The first cleaning seat triggers the second cleaning seat to clean the second purification plate in sequence through linear motion. During the cleaning process, each purification plate does not need to be removed. The linkage relationship enables rapid cleaning of each level of purification surface, improving cleaning efficiency.

[0030] The above and other embodiments and advantages 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.

[0031] In one implementation, such as Figures 1-8 As shown: An alloy smelting waste gas recovery and treatment device includes a purification chamber 10, an activated carbon purification assembly 20, an anti-clogging mechanism 40, and a reciprocating mechanism 50. The activated carbon purification assembly 20 includes a first purification plate 210 and a second purification plate 220 disposed within the purification chamber 10 but not at the same angular orientation. The anti-clogging mechanism 40 includes a first cleaning seat 410 disposed on the purification surface of the first purification plate 210 and a second cleaning seat 420 disposed on the purification surface of the second purification plate 220. The transmission part of the reciprocating mechanism 50 is disposed opposite to each other within the purification chamber 10 and drives the first... The cleaning seat 410 moves linearly along the cleaning surface of the first cleaning plate 210. The second cleaning seat 420 is positioned opposite the first cleaning seat 410 on the linear path. When it is crushed by the first cleaning seat 410, it moves linearly along the cleaning surface of the second cleaning plate 220. There are several second cleaning plates 220. There is a cleaning area a between two second cleaning plates 220 and the first cleaning plate 210. The cleaning area of ​​the first cleaning plate 210 is located above the last cleaning area a. When the second cleaning seat 420 moves in the opposite direction after being crushed by the first cleaning seat 410, it triggers the vibration of the first cleaning plate 210.

[0032] Exhaust gas enters the purification chamber 10 through the air inlet 105, is purified by the second purification plate 220, and then enters purification zone a. From purification zone a, it enters the next-level second purification plate 220, and from there, it enters the next purification zone a. Finally, it is purified by the rightmost purification surface of the first purification plate 210 before being discharged. The first purification plate 210 and the second purification plate 220 are located in different positions, and multiple second purification plates 220 form multiple purification zones a on the air inlet side of the first purification plate 210. This allows the exhaust gas to be differentiated by multiple purification zones a before purification, increasing the purification area and reducing the workload of the first purification plate 210 per unit area. This allows the exhaust gas to undergo secondary purification after multiple purification units, which not only improves the purification quality but also extends the clogging time of each purification surface and reduces the cleaning frequency.

[0033] When the first cleaning seat 410 moves away from the first second cleaning seat 420 to the next first cleaning seat 410, the first second cleaning seat 420 will automatically spring back to its original position, and its top will once again elastically impact the first purification plate 210, causing the first purification plate 210 to vibrate. The vibration effect will shake dust or sticky substances into the purification zone a, and finally discharge them outward from the bottom of the purification zone a. This assists the first cleaning seat 410 in cleaning the dust or sticky substances on the first purification plate 210, improving the cleaning effect.

[0034] The reciprocating mechanism 50 is activated, which drives the first cleaning seat 410 to move linearly along the cleaning surface of the first purification plate 210. This removes dust or sticky substances adhering to the cleaning surface of the first cleaning seat 410, ensuring effective purification of the first purification plate 210. As the first cleaning seat 410 moves linearly, it also sequentially pushes each second cleaning seat 420, causing each second cleaning seat 420 to move linearly along the second purification plate 220 it is located on. Since the second cleaning seats 420 are positioned on the cleaning surface of the second purification plate 220, their linear movement removes dust or sticky substances adhering to their cleaning surfaces, ensuring effective purification of the second purification plate 220.

[0035] Structurally, when the first cleaning seat 410 cleans the surface of the first purification plate 210, it also drives the second cleaning seat 420 to clean the surface of the second purification plate 220 through a rolling relationship, eliminating the need for a power component. The first cleaning seat 410 triggers the second cleaning seat 420 to clean the second purification plate 220 in sequence through linear motion. During the cleaning process, each purification plate does not need to be removed. The linkage relationship enables rapid cleaning of each level of purification surface, improving the cleaning efficiency.

[0036] like Figure 1 , Figure 3As shown, the purification chamber 10 is a horizontal chamber. The left end of the purification chamber 10 is provided with an air inlet 105 and the right end is provided with an air outlet 106. The first purification plate 210 is horizontally arranged in the purification chamber 10, and the second purification plate 220 is vertically arranged on the bottom side of the first purification plate 210. The first purification plate 210 and the second purification plate 220 are distributed in different positions. After the exhaust gas enters, it passes through the second purification plate 220 for purification in sequence, and then passes through the first purification plate 210 for unified purification before being discharged from the air outlet 106. The first purification plate 210 and the second purification plate 220 are distributed in different positions, so that the first cleaning seat 410 and the second cleaning seat 420 are set opposite each other in different positions, and do not interfere with each other during the cleaning action. The length of the first purification plate 210 covers all the second purification plates 220 to form multiple purification zones a. Therefore, in addition to cleaning the purification surface on the first purification plate 210 (above the rightmost purification zone a in the figure), the first cleaning seat 410 will continue to move to the left and roll over the second cleaning seat 420 on each of the second purification plates 220 in turn, cleaning the dust or sticky substances on the purification surface of the second purification plate 220 in sequence, realizing a sequential cleaning process. The cleaning structure is simple and easy to maintain.

[0037] In another implementation, such as Figure 3 , Figure 4 as well as Figure 6 , Figure 7 As shown, the bottom end of the second cleaning seat 420 is provided with a lifting rod 4204. The lifting rod 4204 extends downward from the outer wall of the end of the second purification plate 220 to near the bottom end of the second purification plate 220. The scraper 4203 consists of several pieces connected from top to bottom on the lifting rod 4204, with a gap between each pair of adjacent scrapers 4203.

[0038] In this embodiment, when the second cleaning seat 420 descends, the lifting rod 4204 pushes all the scrapers 4203 down. Since the scrapers 4203 are distributed from top to bottom on the cleaning surface of the second cleaning plate 220, they can thoroughly scrape away the dust or sticky substances adhering to the cleaning surface when they descend. These scrapers 4203 are arranged in multiple places according to the height of the second cleaning plate 220, and there are gaps between them. After scraping, the dust or sticky substances fall onto the guide plate 101 through the gaps. Therefore, the arrangement of the lifting rod 4204 and the scrapers 4203 makes the structure of the second cleaning seat 420 more reasonable.

[0039] In another implementation, such as Figure 3 , Figure 4 As shown, a baffle plate 101 is provided inside the purification chamber 10. The left end of the baffle plate 101 is connected to the discharge port 104. The bottom end of the second purification plate 220 is connected to the baffle plate 101. The purification surfaces of the first purification plate 210 and the second purification plate 220 face the baffle plate 101. An opening is provided at the connection between the bottom end of the second purification plate 220 and the baffle plate 101. Figure 4 (As shown at the bottom of the second purification plate 220), an exhaust port 104 is provided at the bottom left side inside the purification chamber 10. Dust or sticky substances scraped off from the first purification plate 210 and the second purification plate 220 fall onto the guide plate 101, pass through the opening at the bottom of the second purification plate 220, and are discharged into the exhaust port 104 by the inclined guide plate 101, and finally discharged outward from the exhaust port 104.

[0040] In another implementation, such as Figure 6 , Figure 7 As shown, the second cleaning seat 420 has a retaining cavity 4201 opening from the bottom upwards. The retaining cavity 4201 is fastened to the top of the first purification plate 210, and a spring seat 4202 elastically connected to the top of the second purification plate 220 is provided inside the retaining cavity 4201. Under the elastic support of the top of the spring seat 4202, the top of the second cleaning seat 420 elastically abuts against the bottom purification surface of the first purification plate 210. A scraper 4203 is connected to the bottom of the second cleaning seat 420, and the scraper 4203 contacts the purification surface of the second purification plate 220. The left and right sides of the first cleaning seat 410 are provided with arc-shaped driving parts 4101, and the left and right sides of the second cleaning seat 420 are provided with arc-shaped driven parts 4205 that form a rolling relationship with the arc-shaped driving parts 4101. The bottom of the first cleaning seat 410 is provided with a transition wheel 4102.

[0041] In this embodiment, when the first cleaning seat 410 moves to the left as shown, the arc-shaped driving part 4101 on the left side presses against the arc-shaped driven part 4205 on the right side of the second cleaning seat 420. The arc-shaped driven part 4205 drives the second cleaning seat 420 to descend. During this process, the top surface of the second cleaning seat 420 makes rolling contact with the transition wheel 4102 at the bottom of the first cleaning seat 410, thereby increasing the descent range of the second cleaning seat 420. At the same time, when the second cleaning seat 420 descends, it also pushes the spring seat 4202 in its buckling cavity 4201 to compress and store force relative to the top of the second purification plate 220, and the force is stored in the first cleaning seat 420. As 410 continues to move to the left until it leaves the second cleaning seat 420, the spring seat 4202 rebounds upward and pushes the second cleaning seat 420 to rise and reset. At the same time, the top of the second cleaning seat 420 will elastically strike the first purification plate 210 once, causing the first purification plate 210 to vibrate. During the vibration, the residual dust or sticky substances on the purification surface scraped by the first cleaning seat 410 will be shaken off onto the guide plate 101. This makes the linkage between the first cleaning seat 410 and the second cleaning seat 420 more reasonable, and the additional vibration effect improves the cleaning effect of the first cleaning seat 410 on the first purification plate 210. Furthermore, when the first cleaning seat 410 retracts to the right, the arc-shaped drive part 4101 on the right side crushes the arc-shaped driven part 4205 on the left side of the second cleaning seat 420, causing the second cleaning seat 420 to descend again. When the first cleaning seat 410 continues to move to the right and leaves the second cleaning seat 420, the spring seat 4202 rebounds upward again, and the second cleaning seat 420 rises and resets. The top of the second cleaning seat 420 elastically impacts the first purification plate 210 again, causing the first purification plate 210 to vibrate again. This causes the dust or sticky substances remaining on the first purification plate 210 to fall onto the guide plate 101 along the purification zone a. These dust or sticky substances are then carried laterally by the continuously introduced exhaust gas onto the purification surface of the second purification plate 220. After the second purification plate 220 is subsequently scraped to remove dust, these substances will fall onto the guide plate 101 and be discharged outward.

[0042] To accommodate the vibration effect on the first purification plate 210 when the second cleaning seat 420 resets upwards, such as... Figure 5 As shown, the first purification plate 210 is surrounded by a frame 2101. The first hanging plate 102 is installed from the top downward on the left side inside the purification chamber 10, and the second hanging plate 103 is installed from the bottom upward on the right side inside the chamber. The left end of the frame 2101 is connected to the first hanging plate 102, and the right end of the frame 2101 is connected to the second hanging plate 103. The first purification plate 210 is fitted inside the frame 2101, and the outer periphery of the first purification plate 210 is elastically connected to the second hanging plate 103 and the first hanging plate 102 by a spring 2102. The bottom purification surface of the first purification plate 210 protrudes from the bottom of the frame 2101 and contacts the first cleaning seat 410.

[0043] Two purification chambers are formed between the second purification plate 220, the first purification plate 210 and the guide plate 101. The two purification chambers include a first purification chamber 107 which is disposed on the left side of the second purification plate 220 and close to the air inlet 105, and a second purification chamber 108 which is disposed on the right side of the second purification plate 220 and close to the air outlet 106. The lengths of the two ends of the first purification plate 210 involve the first purification chamber 107 and the second purification chamber 108. The first purification chamber 107 covers all purification areas a involving the second purification plate 220. The second purification chamber 108 is designed for the following purposes: the second purification plate 220 has an opening at one end connected to the guide plate 101. When dust or sticky substances shaken off or scraped off the first hanging plate 102, and dust or sticky substances scraped off the second purification plate 220 fall onto the guide plate 101, they will flow through the bottom opening of the second purification plate 220 to the discharge port 104 for discharge. When the exhaust gas enters the purification area a and is purified sequentially by the second purification plate 220, some exhaust gas will inevitably enter the purification area a or the second purification chamber 108 through the opening at the bottom of the second purification plate 220. When they pass through the first purification plate 210, they will still be intercepted and purified by the first purification plate 210. Therefore, the first purification plate 210 covers all the second purification plates 220, and the structure is reasonable.

[0044] The present invention also provides a method for recovering and treating alloy smelting waste gas, using the alloy smelting waste gas recovery and treatment device described above, comprising the following steps:

[0045] a. Waste gas cooling: The alloy smelting waste gas is cooled to 40-60℃ through a cooling unit;

[0046] b. Deacidification treatment: Cooling exhaust gas is sent into purification chamber 10 through air inlet 105, and after being purified by first purification plate 210 and second purification plate 220 in first purification chamber 107 and second purification chamber 108, it is discharged through air outlet 106.

[0047] c. Purification treatment: The equipment supplying alloy smelting waste gas is shut down. The reciprocating mechanism 50 drives the first cleaning seat 410 to clean the blockages on the purification surface of the first purification plate 210. At the same time, the first cleaning seat 410 drives the second cleaning seat 420 to clean the blockages on the purification surface of the second purification plate 220, so as to ensure that the first purification chamber 107 and the second purification chamber 108 will operate normally the next time they are used.

[0048] It should be further explained that the reciprocating mechanism 50 mentioned in this invention can be a conveyor belt drive mode as shown in the figure. A rod is connected to the conveyor belt. When the conveyor belt is driven by the motor to move the rod in a straight line, the rod drives the first cleaning seat 410 in a straight line. By controlling the forward and reverse rotation of the motor, the first cleaning seat 410 is driven to move in a straight line from left to right. Of course, the reciprocating mechanism 50 is only one embodiment in this invention. It can also be other embodiments that can drive the first cleaning seat 410 to move in a straight line, such as a crank-slider mechanism or other mechanical transmission methods. The prior art will not be described in detail.

[0049] It should be further explained that although the scrapers 4203 on the same second purification plate 220 have a limited downward range, they are still sufficient to clean the effective purification area on the second purification plate 220. Moreover, the present invention improves the second purification plate 220 by setting multiple sets of second purification plates 220 to improve purification efficiency. Even if some areas are not set with purification zones, it can make up for the deficiency of insufficient purification by a single second purification plate 220, which is logical and meets the actual needs.

[0050] It should be further explained that the first cleaning seat 410 and scraper 4203 are multi-functional cleaning structures. They are equipped with a flushing pipe 60, one end of which extends to the outer end of the first cleaning seat 410 and scraper 4203, and is connected to an external high-pressure water source (purification liquid) via a hose. The first cleaning seat 410 moves linearly left and right, using its contour to scrape and clean dust and sticky substances from the first purification plate 210. Simultaneously, numerous nozzles on the flushing pipe 60 aim at the holes in the first purification plate 210 to flush the surface. The blockages in the channels are flushed outwards; similarly, the scraper 4203 moves up and down, using its contour to scrape and clean the dust and sticky substances on the second purification plate 220, while the numerous nozzles on its internal flushing pipe 60 are aimed at the channels on the first purification plate 210 to flush out the blockages in the channels. The sewage finally falls onto the guide plate 101. At this time, the guide plate 101 not only ensures that the dust and sticky substances are efficiently discharged from the guide plate 101 into the discharge port 104, but also constitutes a sewage receiving structure.

[0051] It needs to be further explained that, such as Figure 4 As shown, in order to ensure that the second purification plate 220 has sufficient purification surface, the air receiving surface of the second purification plate 220 can also be set as the entire purification surface. In order to prevent the presence of the scraper 4203 from affecting the efficiency of the second purification plate 220, through holes can be opened on the scraper 4203 during actual assembly. After the exhaust gas enters, it passes through the through holes on the scraper 4203 and is blown towards the second purification plate 220, ensuring that the second purification plate 220 purifies efficiently.
