Description

Technical Field

[0001] The invention relates to the technical field of acid mist purification treatment, in particular to an acid mist purification device for uniform spraying used in zinc smelting. Background Art

[0002] The acid mist produced in the zinc smelting process is a complex mixture, which contains harmful substances such as sulfur dioxide, nitrogen oxides, volatile organic compounds and heavy metals. These pollutants have significant harm to human health and the environment. For example, sulfur dioxide and nitrogen oxides are the main causes of acid rain and will cause damage to the ecological environment; heavy metals such as lead, cadmium, mercury, etc. are toxic and cumulative. Long-term exposure may cause a variety of diseases, and then the acid mist needs to be purified. The common purification treatment is spray purification in a spray tower. First, the waste gas (including acid mist) generated in the zinc smelting process is collected through a gas collection hood or pipeline and sent to the spray tower for treatment. After the waste gas enters the spray tower, it is fully contacted with the droplets of purification liquid sprayed from the spray device and a chemical reaction occurs. Most of the harmful substances in the waste gas after spray purification have been removed or converted into harmless substances. At this time, the gas and liquid are separated by a separation device (such as a packing layer) in the tower, and the purified gas is discharged from the top of the tower, while the purified liquid containing pollutants flows into the storage tank for subsequent treatment or recycling.

[0003] The acid mist purification process through uniform spraying can ensure that the purification liquid and the acid mist are in full contact and chemically react, thereby improving the purification efficiency. However, in actual use, the acid mist may contain other impurities and sticky substances, which are prone to cause bonding after being deposited on the surface of the filler. When the filler shells are bonded together, the gaps between the fillers will become smaller or even disappear, resulting in increased resistance to gas passing through the filler layer and reduced gas-liquid contact area, which will directly affect the gas-liquid contact efficiency and reduce the reaction rate between the acid mist and the spray liquid, thereby affecting the purification effect. For this reason, we propose an acid mist purification device with uniform spraying for zinc smelting. Summary of the invention

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] The acid mist purification device for uniform spraying for zinc smelting uses an action rod group to act on the fillers on the filler layer group, so that the fillers that are bonded to each other are separated by the action, and under the action of the rolling ball, the sticky impurities on the surface of the filler can be effectively removed, and the bonding rate between the fillers can be reduced. The sponge action on the wiping part can effectively remove impurities on the surface of the rolling ball, thereby avoiding clogging of the filler layer group and improving the purification effect.

[0017] The acid mist purification device for uniform spraying for zinc smelting utilizes the magnetic relationship between the electromagnet body and the magnetic end of the movable plate frame so that the movable plate frame drives the wiping part to move, and then the sponge on the wiping part can act on the rolling ball. The area of ​​the rolling ball located outside the action rod frame will roll to the inside of the action rod frame and be wiped by the sponge, while the area of ​​the rolling ball located inside the action rod frame will roll to the outside of the action rod frame and continue to wipe the filler.

[0018] The acid mist purification device for uniform spraying for zinc smelting utilizes a connecting shaft body rotatably connected to a movable plate frame, so that when the sponge on the wiping part acts on a rolling ball, the sponge on the wiping part is also acted on by the rolling ball. Under the action of the connecting shaft body, the wiping part and the sponge thereon are adjusted in angle to change the wiping area for the rolling ball.

[0019] The acid mist purification device for uniform spraying for zinc smelting can effectively reduce the rising speed of bubble-like droplets by using a retaining rod group. The retaining rod group rotates due to the rising force of the bubble-like droplets. During the rotation process, the retaining rod group usually throws out the bubble-like droplets at the highest point, and then the retaining rod group can effectively reduce the rising speed of the bubble-like droplets, so that the bubble-like droplets formed by the acid mist and the purification liquid fully react with the purification liquid, and the sticky substances can be removed under the action of the purification liquid.

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] See also Figure 1-12 A zinc smelting uniform spray acid mist purification device, the present invention aims at solving the technical problems in the background technology, comprising a spray tower 1, a packing layer group 2 fixedly installed inside the spray tower 1, a plurality of mounting sleeves 3 fixedly installed on the packing layer group 2, and a plurality of mounting sleeves 3 fixedly installed on the packing layer group 2. Figure 1 and attached Figure 2 As shown, the packing layer group 2 is composed of a plurality of packing panels, each of which needs to be filled with a packing part (the packing part is a prior art, not shown in the figure, and the specific shape can be referred to in the attached Fig.10 ), a rotating shaft body 4 rotatably connected to its inner wall is installed inside the mounting sleeve 3, and one end of the rotating shaft body 4 penetrates the inner wall of the mounting sleeve 3 and extends to the outside. It should be noted that, except for the packing panel at the lowest point inside the spray tower 1, the mounting sleeves 3 at the bottom of the remaining packing panels are all installed with rotating shaft bodies 4, and a mounting ring 41 is fixedly installed at one end of the rotating shaft body 4 located outside the mounting sleeve 3, and a plurality of sheet-type brackets 42 are fixedly installed on the mounting ring 41. The material of the sheet-type bracket 42 is preferably a rigid material, and a corrosion-resistant coating can be applied on the surface of the sheet-type bracket 42. A plurality of action rod frames 43 are fixedly connected to each sheet-type bracket 42, and the action rod frames 43 are in contact with the packing. A driving mechanism 5 for driving the rotating shaft body 4 to rotate is also provided inside the mounting sleeve 3. During the rotation of the action rod frame 43, it contacts the packing and separates the bonded packing shell, combined with the attached Fig.10As shown, the action rod frame 43 acts on the fillers on the packing layer group 2 during the rotation process, so that the fillers on the packing layer group 2 that are bonded to each other are separated by the action of the action rod frame 43. In order to reduce the bonding rate between the fillers, the present invention is designed as follows:

[0035] A movable plate frame 44 is installed inside the action rod frame 43 and is slidably connected to the inner wall thereof, and one end of the movable plate frame 44 is a magnetic end, and a return spring 45 is connected between the other end of the movable plate frame 44 and the inner wall of the action rod frame 43, and an electromagnet body 46 is arranged on one side of the magnetic end of the movable plate frame 44, and the electromagnet body 46 is fixedly connected to the inner wall of the action rod frame 43, and the electromagnet body 46 is energized to generate a repulsive force on the magnetic end of the movable plate frame 44, and a plurality of connecting shafts 47 rotatably connected to the inner wall thereof are installed on the action rod frame 43, and both ends of each connecting shaft 47 are fixedly mounted. A wiping portion 48 for placing a sponge is provided, and the rolling ball 431 corresponds to the wiping portion 48 one by one. When the wiping portion 48 moves with the movable plate frame 44, the sponge on the wiping portion 48 acts on the rolling ball 431, and the rolling ball 431 rolls under the force of the sponge, that is, the area of ​​the rolling ball 431 located outside the action rod frame 43 will roll to the inside of the action rod frame 43 and be wiped by the sponge, and the area of ​​the rolling ball 431 located inside the action rod frame 43 will roll to the outside of the action rod frame 43 and continue to wipe the filler;

[0036] In conjunction with the above, Figure 10-12As shown, when the rotating shaft 4 rotates, the mounting ring 41 at its end drives the sheet bracket 42 to rotate, so that the sheet bracket 42 drives the action rod 43 to rotate. The action rod 43 acts on the filler on the packing layer group 2 during the rotation process, so that the fillers on the packing layer group 2 that are in a mutually bonded state are separated by the action rod 43. When the action rod 43 acts on the filler, since there are more fillers on the packing layer, the rolling ball 431 on the action rod 43 will be affected by the filler, and the rolling ball The body 431 can wipe off the impurities on the surface of the filler; at the same time, the electromagnet body 46 is energized to generate a repulsive force on the magnetic end of the moving plate frame 44, and the moving plate frame 44 slides within the action rod frame 43 and squeezes the return spring 45. During the movement of the moving plate frame 44, the sponge on the wiping portion 48 will exert a force on the rolling ball 431 on the movement trajectory, so that the rolling ball 431 rotates due to the force of the sponge, and then the area of ​​the rolling ball 431 located outside the action rod frame 43 will roll The electromagnet body 46 moves to the inside of the action rod frame 43 and is wiped by the sponge, while the area of ​​the rolling ball 431 located inside the action rod frame 43 will roll to the outside of the action rod frame 43 and continue to wipe the filler. Under normal circumstances, the amount of electricity energized by the electromagnet body 46 is constant each time, and thus the distance moved by the moving plate frame 44 is also constant each time. When the moving plate frame 44 moves to the end each time, the sponge on the wiping portion 48 will separate from the rolling ball 431. When the electromagnet body 46 is powered off, the moving plate frame 44 moves in the reverse direction under the action of the reset spring 45. Movement, the sponge on the wiping portion 48 will act on the rolling ball 431 again. It should be noted that, due to the rotational connection between the connecting shaft 47 and the movable plate frame 44, when the sponge on the wiping portion 48 acts on the rolling ball 431, if the rolling ball 431 is subjected to a large reaction force of the packing, the sponge on the wiping portion 48 will also be subjected to the action of the rolling ball 431. Under the action of the connecting shaft 47, the wiping portion 48 and the sponge thereon are adjusted in angle to change the wiping area for the rolling ball 431.

[0037] As a further limitation of the present invention, the driving mechanism 5 includes a connecting sleeve 51 fixedly connected to the mounting sleeve 3, and the interior of the connecting sleeve 51 is in a communicating state with the interior of the mounting sleeve 3, and a driving gear 52 rotatably connected to its inner wall is installed inside the connecting sleeve 51, and a driven gear 53 meshing with the driving gear 52 is fixedly installed on the rotating shaft 4, and the radius and the number of teeth of the driving gear 52 are greater than those of the driven gear 53, wherein a guide shaft 54 ​​is fixedly installed inside the connecting sleeve 51, and a gear 53 slidably connected to its outer wall is installed on the guide shaft 54. A magnetic shaft 55 is dynamically connected, and a spiral groove 551 is arranged on the outer wall of the magnetic shaft 55, wherein a sliding shaft 521 is fixedly installed on the inner wall of the driving gear 52, and the sliding shaft 521 can slide within the spiral groove 551 within a limited position, and an electric magnetic group 56 is fixedly installed on the inner wall of the top of the connecting sleeve 51, and the electric magnetic group 56 generates a repulsive force on the end of the magnetic shaft 55 when energized, and a constant force spring 57 is also arranged between the end of the magnetic shaft 55 away from the electric magnetic group 56 and the inner wall of the bottom of the connecting sleeve 51, and the constant force spring 57 is sleeved on the guide shaft 54;

[0038] In conjunction with the above, Figure 6-9 As shown, the electric magnetic group 56 is energized to generate a repulsive force on the end of the magnetic shaft 55, and the magnetic shaft 55 slides within the upper limit on the guide shaft 54 ​​and compresses the constant force spring 57. The amount of current flowing through the electric magnetic group 56 can be gradually increased. During the descent of the magnetic shaft 55, the spiral groove 551 thereon will exert an effect on the sliding shaft 521 on the inner wall of the driving gear 52, and then the driving gear 52 rotates under the action of the sliding shaft 521. During the rotation of the driving gear 52, it meshes with the driven gear 53, and then the driven gear 53 drives the rotating shaft 4 to rotate within the installation sleeve 3 within the limit, so that the installation ring 41 and the multiple sheet-type brackets 42 thereon can rotate synchronously with the rotating shaft 4.

[0039] The acid mist contacts with the purification night to form bubble-like droplets, but in actual use, the bubble-like droplets often fail to fully contact with the sprayed droplets due to their too fast rising speed, which may cause the harmful substances in the acid mist to fail to be fully absorbed or reacted, on the one hand reducing the purification efficiency, and on the other hand, the short contact time may also make the chemical reaction incomplete, causing the viscous substances in the acid mist to enter the packing layer group 2 to increase the probability of clogging of the packing layer group 2. In view of this, the present invention is designed as follows: a plurality of connecting rod frames 6 are fixedly installed on the outer wall of the mounting sleeve 3, and the ends of the connecting rod frames 6 are inclined (such as the attached Figure 2As shown in the figure, an annular sleeve 61 is fixedly installed at the end of each connecting rod frame 6, and a transmission shaft body 62 rotatably connected to the inner wall of the annular sleeve 61 is installed inside the annular sleeve 61, and one end of the transmission shaft body 62 passes through the inner wall of the annular sleeve 61 and extends to the outside thereof, and a plurality of intercepting rod groups 63 are installed in parallel in the area where the transmission shaft body 62 is located outside the annular sleeve 61, and each intercepting rod group 63 is composed of a plurality of threaded rods 64 distributed in an annular shape and at equal intervals, and is combined with the attached Figure 4 As shown, the lengths of the plurality of intercepting rod groups 63 in the present invention increase from bottom to top along the center line of the transmission shaft 62, and then the acid mist (including the gas-liquid mixture after contact and mixing) will act on the intercepting rod group 63 on the transmission shaft 62 during the rising process, and the intercepting rod group 63 will rotate due to the rising force, and the acid mist will be hindered by the intercepting rod group 63 in this process, and will form bubble-like droplets after contacting with the droplets, and the bubble-like droplets are easy to adhere to the surface of the intercepting rod group 63, and the intercepting rod group 63 will usually throw out the bubble-like droplets at the highest point during the rotation process, and then the intercepting rod group 63 can be used to effectively reduce the rising speed of the bubble-like droplets, so that the bubble-like droplets formed by the acid mist and the purified liquid fully react with the purified liquid, and the sticky substances can be removed under the action of the purified liquid. To this end, a fixed sleeve can be installed on the packing panel at the lowest point inside the spray tower 1, and a connecting rod frame 6 and its upper components (such as attached) can be installed on the fixed sleeve. Figure 1 shown);

[0040] One end of the transmission shaft 62 located inside the annular sleeve 61 is also connected to a reciprocating screw 65, and the end of the reciprocating screw 65 is rotatably connected to the inner wall of the annular sleeve 61, and a driving slider 66 is installed on the reciprocating screw 65, and a limit shaft 67 is fixedly installed on the inner wall of the annular sleeve 61, and the driving slider 66 slides on the limit shaft 67. A sensing element 68 is fixedly installed on the inner wall of the annular sleeve 61, and the sensing element 68 is located on the motion trajectory of the driving slider 66, wherein the sensing element 68 and the electrical magnetic group 56 are connected. When the intercepting rod group 63 drives the transmission shaft 62 to rotate, the reciprocating screw 65 on the transmission shaft 62 will move synchronously with it, so that the driving slider 66 slides within the limit limit of the limit shaft 67, and applies a force to the sensing element 68 during the movement, and the sensing element 68 controls the electric magnetic group 56 to be energized. It should be noted that each time the electric magnetic group 56 is energized, the electromagnet body 46 is also energized, and the energization time of each electric magnetic group 56 and the electromagnet body 46 can be set through the terminal;

[0041] In conjunction with the above, Figure 3-5As shown, the bubble-like droplets will act on the intercepting rod group 63 during the rising process. Since the lengths of the multiple intercepting rod groups 63 increase from bottom to top along the center line of the transmission shaft 62, the intercepting rod group 63 will rotate due to the rising force, and the threaded rods 64 on the intercepting rod group 63 will intercept the bubble-like droplets, and usually throw the bubble-like droplets out at the highest point, thereby effectively reducing the rising speed of the bubble-like droplets, so that the bubble-like droplets formed by the acid mist and the purification liquid can fully react with the purification liquid.
