Description

Technical Field

[0001] The invention relates to the technical field of waste gas treatment, in particular to waste gas treatment equipment for potassium permanganate production with an aggregate purification function. Background Art

[0002] Potassium permanganate is a strong oxidant and disinfectant, commonly used in water treatment, disinfection, medicine, metallurgy and other fields. Currently, potassium permanganate will produce sulfides and nitrides during the production process, and the waste gas will also contain a large amount of particulate matter. In order to avoid environmental pollution, most companies will set up a waste gas treatment equipment outside the potassium permanganate production plant.

[0003] At present, waste gas treatment equipment for potassium permanganate production usually uses dust removal equipment, spray towers, etc. The dust collector is used to remove solid particles in the waste gas, and the spray tower is used to absorb harmful gases in the waste gas into liquid. For example, the patents "Announcement No. CN115779597B A tail gas treatment device" and "CN117398833B An industrial waste gas treatment equipment" are generally unable to centrally treat the particles intercepted on the filter screen while ensuring the flow of waste gas. The fan needs to be shut down every time the particles intercepted by the dust removal equipment are treated. Finally, when using the spray tower to treat the waste gas, in order to ensure the effect of the waste gas treatment, the staff often sets a packing layer and a demister plate in the spray tower. However, the height and spacing of the packing layer and the demister plate used in the spray tower on the market are fixed, and the height of the packing layer or the spacing of the demister plate cannot be adjusted in real time according to the flow of the waste gas, which sometimes causes the waste gas treatment effect to fail to meet the needs of the staff. Summary of the invention

[0004] The object of the present invention is to provide a waste gas treatment device for potassium permanganate production with aggregate purification function to solve the problems raised in the above background technology.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: a waste gas treatment device for potassium permanganate production with aggregate purification function, the waste gas treatment device comprising a base, a spray tower and a fan, the spray tower is arranged on the base, the fan is arranged on the outside of the base, the top of the spray tower is connected to the air intake end of the fan through an exhaust pipe, the interior of the base is provided with a purification chamber and a connecting chamber, the purification chamber is connected to the potassium permanganate production chamber through an air collection pipe, the connecting chamber is connected to the spray tower through an air intake pipe, an aggregate assembly is arranged in the purification chamber, the purification chamber is connected to the connecting chamber through the aggregate assembly, when the present invention is working, the waste gas in the potassium permanganate production chamber is sucked out by the fan, at this time the waste gas will flow along the air collection pipe-purification chamber-connecting chamber-air intake pipe-spray tower-exhaust pipe, and the waste gas in the purification chamber will flow along the air collection pipe-purification chamber-connecting chamber-air intake pipe-spray tower-exhaust pipe, and the waste gas in the purification chamber will flow along the air collection pipe-purification chamber-connecting chamber-air intake pipe-spray tower-exhaust pipe The set aggregate assembly can collect the particulate matter in the exhaust gas for treatment and achieve the purpose of preliminary purification. The base is also provided with a liquid storage chamber and a liquid pump. The liquid storage chamber is provided with an alkaline solution. The lower end of the spray tower is connected with the liquid storage chamber, the liquid inlet end of the liquid pump is connected with the liquid storage chamber, and the liquid outlet end of the liquid pump is connected with the spray pipe through a discharge pipe. The interior of the spray tower is provided with a packing assembly, a spray pipe and a defogger mechanism. The spray pipe and the defogger mechanism are sequentially arranged above the packing assembly, and a nozzle is arranged below the spray pipe. The alkaline solution is continuously input into the spray pipe through the liquid pump to remove the acidic gas in the exhaust gas. The packing assembly is used to ensure that the exhaust gas can fully react with the alkaline solution. The defogger mechanism is used to remove droplets in the exhaust gas to prevent the exhaust gas from carrying more droplets into the fan after purification.

[0006] Furthermore, a motor is provided on the outside of the base, a discharge trough is provided on the side end of the purification chamber, the collection assembly includes a fixed cylinder, a through hole is provided on one end of the fixed cylinder close to the connecting chamber, the end of the fixed cylinder away from the connecting chamber is connected to the working end of the motor, four groups of collection holes are provided on the fixed cylinder, a group of filter screens are provided in each group of the collection holes, a positioning rod and a second sealing plate are provided in the fixed cylinder, one end of the positioning rod extends into the connecting chamber and is fixedly connected to the inner wall of the connecting chamber, the second sealing plate is provided in one end of the fixed cylinder close to the discharge trough, one end of the second sealing plate is fixedly connected to the positioning rod through a connecting frame, and the other end of the second sealing plate is connected to the fixed cylinder The inner wall of the second sealing plate is in contact with the inner wall, the width of the second sealing plate is greater than the width of the collection hole. When the exhaust gas enters the purification chamber, it will pass through the collection hole on the fixed cylinder, and then enter the connecting chamber along the through hole. The particulate matter in the exhaust gas is intercepted by the filter on the collection hole. A particle detector is arranged in the connecting chamber. The particle detector is used to detect whether the filter in the collection hole is normal. If the filter in one group of collection holes is damaged, the particle detector will detect a large amount of particulate matter in the connecting chamber. At this time, the staff can drive the fixed cylinder to rotate by the motor, so that the damaged filter can be moved to the vicinity between the second sealing plate and the discharge trough to prevent subsequent exhaust gas from passing through the damaged filter.

[0007] Furthermore, in the present invention, each group of filter screens can be detachably installed in the collection hole, and a first sealing plate is provided at one end of the discharge trough close to the purification chamber. Two groups of the first sealing plates are provided, and the two groups of the first sealing plates are relatively arranged at the upper and lower ends inside the discharge trough. The ends of the two groups of the first sealing plates close to each other are detachably connected, and the two groups of the first sealing plates are in contact with the outer wall of the fixed cylinder. During normal working of the present invention, the two groups of the first sealing plates are connected together, and the purification chamber and the discharge trough are separated by the two groups of the first sealing plates to prevent exhaust gas from being discharged into the external environment. If the staff needs to perform maintenance on a certain group The particulate matter collected on the filter can be processed by driving the fixed cylinder to rotate through a motor until the filter to be processed moves between the second sealing plate and the discharge trough, and then the two sets of first sealing plates are opened. At this time, the staff can take out the filter to be processed from the collection hole, so as to collect the particulate matter intercepted by the filter for centralized processing. Compared with the current filtering mechanism, the present invention can, on the one hand, centrally process the particulate matter intercepted on the filter while ensuring the flow of exhaust gas, and on the other hand, prevent the exhaust gas from escaping from the purification chamber without being purified during the movement of the filter, thereby ensuring the treatment effect of the exhaust gas.

[0008] Furthermore, the interior of the spray tower is a rectangular chamber, and the storage mechanism includes a first storage rack and a second storage rack, which are relatively arranged on both sides of the outer end of the spray tower, and the packing assembly includes a first packing tray and a second packing tray, and the first packing tray is provided with several groups, and each group of the first packing trays is connected to the first storage rack through a group of linear drive components (the linear drive component can select a lead screw, a linear motor, etc. as needed), and the second packing tray is provided with several groups, and each group of the second packing trays is connected to the second storage rack through a group of linear drive components, and each group of the first packing trays is aligned with a group of second packing trays. The present invention can drive several groups of first packing trays and several groups of second packing trays to move in the spray tower through several groups of linear drive components, so as to facilitate the staff to timely adjust the height of the packing assembly according to the flow rate of the exhaust gas and the flow rate of the alkaline solution. Compared with the packing layer in the current spray tower, the present invention can ensure that the alkaline solution stays in the packing layer for a sufficiently long time on the basis of ensuring that the alkaline solution passes through the packing assembly smoothly.

[0009] Furthermore, the first filling tray and the second filling tray in the present invention have the same structure. Taking the first filling tray as an example in this embodiment, a storage tank is arranged inside the first filling tray, air holes are arranged at the upper and lower ends of the storage tank, and fillers are arranged in the storage tank. A positioning plate is arranged at the end of the first filling tray away from the first storage rack, and the positioning plate is connected to the inner wall of the spray tower through a slider and a slide groove. A sealing cover is arranged at the end of the first filling tray close to the first storage rack, and the sealing cover is detachably connected to the first filling tray by bolts. During the working process of the present invention, if the filler is blocked or the like, the staff can align a group of relative positions in turn through the linear drive component. The first filling tray and the second filling tray are moved into the first storage rack and the second storage rack. When the first filling tray and the second filling tray are located in the first storage rack and the second storage rack, the positioning plates on the first filling tray and the second filling tray will isolate the area in the spray tower from the area in the storage mechanism, so as to avoid leakage of exhaust gas. At the same time, the staff can remove the sealing cover from the first filling tray and the second filling tray, so as to facilitate the staff to replace the packing in the first filling tray and the second filling tray. Compared with the current packing layer in the spray tower, the present invention can replace the packing in the packing layer while ensuring the normal purification of the exhaust gas, so as to prevent the machine from being shut down for maintenance when the packing layer is blocked.

[0010] Furthermore, a valve is provided on the discharge pipe, and a group of first electromagnets are provided at both left and right ends of the inside of the spray pipe. A group of pressure plates are provided on the sides where the two groups of first electromagnets are close to each other, and the ends of the two groups of pressure plates that are away from each other are magnetic. A piezoelectric sheet is provided on the ends of the two groups of pressure plates that are close to each other. During normal operation of the present invention, the valve on the discharge pipe is always in an open state. When the nozzle under the spray pipe is blocked by impurities, the pressure in the spray pipe will increase. At this time, the piezoelectric sheet on the pressure plate will generate a group of electrical signals. When the present invention detects that the nozzle is blocked, the staff can close the valve and open the two groups of first electromagnets. At this time, the two groups of first electromagnets will generate a group of magnetic fields that repel the two groups of pressure plates, so that the two groups of pressure plates tend to approach each other. Since the liquid is incompressible, the force applied by the two groups of first electromagnets to the two groups of pressure plates will be transmitted to the nozzle, thereby causing the impurities to be sprayed out of the nozzle, thereby ensuring that the alkaline solution flows smoothly into the spray tower.

[0011] Furthermore, the defogger mechanism includes defogger plates and support rods, the defogger plates are provided with several groups, the support rods are provided with two groups, the two groups of support rods penetrate the several groups of defogger plates, the several groups of defogger plates are arranged at the upper end of the spray tower through the two groups of support rods, the present invention is provided with a flow detector in the connecting cavity, and during operation, the flow rate of exhaust gas entering the spray tower per unit time is detected by the flow detector, the defogger plates in the present invention include a first bracket and a second bracket, the second bracket is fixedly mounted on the support rod, the first bracket is movably mounted inside the second bracket, and second electromagnets are provided at the upper and lower ends of the first bracket and the second bracket, and the staff can control the first bracket to move in the second bracket through the two groups of the second electromagnets, and then adjust the spacing of the several groups of defogger plates in real time according to the flow rate of the exhaust gas, on the one hand, avoiding the large spacing of the several groups of defogger plates and the low efficiency of removing droplets, and on the other hand, preventing the spacing of the several groups of defogger plates from being too small, which leads to increased energy consumption.

[0012] Furthermore, a plurality of exhaust holes are provided on the first bracket, and sealing gaskets are provided in the areas where the first bracket, the second bracket and the support rod are in contact. During operation of the present invention, if droplets gather between the two groups of defogger plates, the first bracket can be moved in the second bracket through the two groups of second electromagnets. At this time, the exhaust holes will intermittently discharge a group of gases, so as to avoid droplets clogging the areas between the groups of defogger plates and ensure that the exhaust gas can flow smoothly between the groups of defogger plates.

[0013] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: compared with the current waste gas treatment equipment, the present invention is provided with an aggregate component, through which the particulate matter in the waste gas can be concentrated for treatment, and at the same time, the purpose of preliminary purification is achieved. Compared with the current filtering mechanism, the aggregate component of the present invention can, on the one hand, centrally treat the particulate matter intercepted on the filter screen on the basis of ensuring the flow of waste gas, and on the other hand, it can prevent the waste gas from escaping from the purification chamber without being purified during the movement of the filter screen, thereby ensuring the treatment effect of the waste gas. The present invention is also provided with a packing component, and the packing component includes a first packing disc and a second packing disc. Compared with the packing layer in the current spray tower, the packing component in the present invention can adjust the height in time according to the flow rate of the waste gas and the flow rate of the alkaline solution, thereby ensuring that the alkaline solution passes smoothly through the packing component. On the basis, it is ensured that the alkaline solution stays in the packing layer for a sufficiently long time. In addition, the packing assembly in the present invention can also replace the packing in the packing assembly while ensuring the normal purification of the exhaust gas, so as to prevent the machine from being shut down for maintenance when the packing assembly is blocked. Finally, the present invention is also provided with a defogger mechanism, which removes droplets in the exhaust gas to prevent the exhaust gas from carrying more droplets into the fan after purification. Compared with the current defogger plates, the present invention can adjust the spacing between several groups of defogger plates in real time according to the flow rate of the exhaust gas. If droplets gather between two groups of defogger plates, the two groups of second electromagnets can also make the first bracket circulate in the second bracket. At this time, the exhaust hole will intermittently discharge a group of gas to avoid droplets clogging the area between several groups of defogger plates, thereby ensuring that the exhaust gas can flow smoothly along the several groups of defogger plates.

When the present invention is working, the waste gas in the potassium permanganate production chamber is sucked out by the fan 7, and at this time the waste gas will flow along the air collection pipe 3-purification chamber 12-connecting chamber 14-air intake pipe 2-spray tower 5-exhaust pipe 6, and the waste gas will flow along the air collection pipe 3-purification chamber 12-connecting chamber 14-air intake pipe 2-spray tower 5-exhaust pipe 6, and the waste gas will flow along the air collection pipe 3-purification chamber 12-connecting chamber 14-air intake pipe 2-spray tower 5-exhaust pipe 6, and the waste gas will flow along the air collection pipe 3-purification chamber 12-connecting chamber 14-air intake pipe 2-spray tower 5-exhaust pipe 6. The particulate matter in the exhaust gas can be concentrated for treatment, and at the same time, it can achieve the purpose of preliminary purification. A liquid storage chamber 15 and a liquid pump 16 are also provided in the base 1. An alkaline solution is provided in the liquid storage chamber 15. The lower end of the spray tower 5 is connected to the liquid storage chamber 15, and the liquid inlet end of the liquid pump 16 is connected to the liquid storage chamber 15. The liquid outlet end of the liquid pump 16 is connected to the spray pipe 52 through the discharge pipe 8. A packing assembly 51, a spray pipe 52 and a defogger 53 are provided inside the spray tower 5. The spray pipe 52 and the defogger 53 are sequentially arranged above the packing assembly 51, and a nozzle is provided below the spray pipe 52. The alkaline solution is continuously input into the spray pipe 52 through the liquid pump 16 to remove the acidic gas in the exhaust gas. The packing assembly 51 ensures that the exhaust gas can fully react with the alkaline solution. The defogger 53 removes droplets in the exhaust gas to prevent the exhaust gas from carrying more droplets into the fan 7 after purification.

[0028] like Figure 2-Figure 5As shown, a motor 11 is arranged on the outside of the base 1, a discharge groove 122 is arranged on the side end of the purification chamber 12, and the collection assembly includes a fixed cylinder 13, and a through hole is arranged at one end of the fixed cylinder 13 close to the connecting chamber 14, and the end of the fixed cylinder 13 away from the connecting chamber 14 is connected to the working end of the motor 11, and four groups of collection holes are arranged on the fixed cylinder 13, and a group of filter screens 131 are arranged in each group of collection holes, and a positioning rod 132 and a second sealing plate 133 are arranged in the fixed cylinder 13, and one end of the positioning rod 132 extends into the connecting chamber 14 and is fixedly connected to the inner wall of the connecting chamber 14, and the second sealing plate 133 is arranged in the fixed cylinder 13 near the end of the discharge groove 122, and one end of the second sealing plate 133 is fixedly connected to the positioning rod 132 through a connecting frame, and the other end of the second sealing plate 133 is connected to the fixed cylinder 13, the width of the second sealing plate 133 is greater than the width of the collection hole. When the exhaust gas enters the purification chamber 12, it will pass through the collection hole on the fixed cylinder 13, and then enter the connecting chamber 14 along the through hole, and the particulate matter in the exhaust gas will be intercepted by the filter 131 on the collection hole. A particle detector is arranged in the connecting chamber 14, and the particle detector is used to detect whether the filter 131 in the collection hole is normal. If the filter 131 in one group of the collection holes is damaged, the particle detector will detect a large amount of particulate matter in the connecting chamber 14. At this time, the staff can drive the fixed cylinder 13 to rotate by the motor 11, so that the damaged filter 131 can be moved to the vicinity of the second sealing plate 133 and the discharge trough 122, so as to prevent the subsequent exhaust gas from passing through the damaged filter 131.

[0029] like Figure 2-Figure 5As shown, each group of filter screens 131 in the present invention can be detachably installed in the collecting hole, and a first sealing plate 121 is provided at one end of the discharge trough 122 close to the purification chamber 12. Two groups of first sealing plates 121 are provided, and the two groups of first sealing plates 121 are relatively arranged at the upper and lower ends inside the discharge trough 122. The ends of the two groups of first sealing plates 121 close to each other are detachably connected, and the two groups of first sealing plates 121 are in contact with the outer wall of the fixed cylinder 13. In the normal working process of the present invention, the two groups of first sealing plates 121 are connected together, and the purification chamber 12 and the discharge trough 122 are separated by the two groups of first sealing plates 121 to prevent the exhaust gas from being discharged into the external environment. If the staff needs to perform a certain operation on a group of filter screens 13 1, the fixed cylinder 13 can be driven by the motor 11 to rotate until the filter screen 131 to be processed moves between the second sealing plate 133 and the discharge groove 122, and then the two sets of first sealing plates 121 are opened. At this time, the staff can take out the filter screen 131 to be processed from the collection hole, so as to collect the particulate matter trapped by the filter screen 131 for centralized treatment. Compared with the current filtering mechanism, the present invention can, on the one hand, centrally treat the particulate matter trapped on the filter screen 131 while ensuring the flow of exhaust gas, and on the other hand, it can prevent the exhaust gas from escaping from the purification chamber 12 without being purified during the movement of the filter screen 131, thereby ensuring the treatment effect of the exhaust gas.

[0030] like Figure 6-Figure 7 As shown, the interior of the spray tower 5 is a rectangular chamber, the storage mechanism 4 includes a first storage rack 41 and a second storage rack 42, the first storage rack 41 and the second storage rack 42 are arranged on both sides of the outer end of the spray tower 5, and the packing assembly 51 includes a first packing tray 511 and a second packing tray 512. The first packing tray 511 is provided with a plurality of groups, and each group of the first packing tray 511 is connected to the first storage rack 41 through a group of linear drive components 43 (the linear drive components 43 can select a lead screw, a linear motor, etc. as needed), and the second packing tray 512 is provided with a plurality of groups, and each group of the second packing tray 512 is connected to the first storage rack 41 through a group of linear drive components 43. A group of linear drive components 43 are connected to the second storage rack 42, and each group of first filling trays 511 is aligned with a group of second filling trays 512. The present invention can drive several groups of first filling trays 511 and several groups of second filling trays 512 to move in the spray tower 5 through several groups of linear drive components 43, so as to facilitate the staff to adjust the height of the filling component 51 in time according to the flow rate of the exhaust gas and the flow rate of the alkaline solution. Compared with the current filling layer in the spray tower 5, the present invention can ensure that the alkaline solution stays in the filling layer for a sufficiently long time on the basis of ensuring that the alkaline solution passes through the filling component 51 smoothly.

[0031] like Figure 6-Figure 7As shown, the first filling tray 511 and the second filling tray 512 in the present invention have the same structure. In this embodiment, the first filling tray 511 is taken as an example. A storage tank 5111 is arranged inside the first filling tray 511. Air holes are arranged at the upper and lower ends of the storage tank 5111. Fillers are arranged in the storage tank 5111. A positioning plate 5113 is arranged at the end of the first filling tray 511 away from the first receiving rack 41. The positioning plate 5113 is connected to the inner wall of the spray tower 5 through a slider and a slide groove. A sealing cover 5112 is arranged at the end of the first filling tray 511 close to the first receiving rack 41. The sealing cover 5112 and the first filling tray 511 are detachably connected by bolts. During the working process of the present invention, if the filler is blocked or the like, the staff can use the linear drive component 43 to sequentially move a group of aligned first filling trays 511. The material tray 511 and the second filling tray 512 are moved to the first storage rack 41 and the second storage rack 42. When the first filling tray 511 and the second filling tray 512 are located in the first storage rack 41 and the second storage rack 42, the positioning plates 5113 on the first filling tray 511 and the second filling tray 512 will isolate the area in the spray tower 5 from the area in the storage mechanism 4 to avoid leakage of exhaust gas. At the same time, the staff can remove the sealing cover 5112 from the first filling tray 511 and the second filling tray 512 to facilitate the staff to replace the packing in the first filling tray 511 and the second filling tray 512. Compared with the current packing layer in the spray tower 5, the present invention can replace the packing in the packing layer while ensuring normal purification of the exhaust gas, thereby preventing the machine from being shut down for maintenance when the packing layer is blocked.

[0032] like Figure 2 , Figure 8 As shown, a valve is provided on the drain pipe 8, and a group of first electromagnets 521 are provided at both left and right ends of the interior of the spray pipe 52. A group of pressure plates 522 are provided on the sides where the two groups of first electromagnets 521 are close to each other. The ends of the two groups of pressure plates 522 that are away from each other are both magnetic, and the ends of the two groups of pressure plates 522 that are close to each other are both provided with piezoelectric sheets. In the normal working process of the present invention, the valve on the drain pipe 8 is always in an open state. When the nozzle under the spray pipe 52 is blocked by impurities, the pressure in the spray pipe 52 will increase. At this time, the pressure plate 522 The piezoelectric sheet on the nozzle will generate a group of electrical signals. When the present invention detects that the nozzle is blocked, the staff can close the valve and turn on the two groups of first electromagnets 521. At this time, the two groups of first electromagnets 521 will generate a group of magnetic fields that repel the two groups of pressure plates 522, so that the two groups of pressure plates 522 tend to approach each other. Since the liquid is incompressible, the force applied by the two groups of first electromagnets 521 to the two groups of pressure plates 522 will be transmitted to the nozzle, thereby causing impurities to be ejected from the nozzle, thereby ensuring that the alkaline solution flows smoothly into the spray tower 5.

[0033] like Figure 9-10As shown, the defogger mechanism 53 includes a defogger plate 531 and a support rod 532. The defogger plates 531 are provided with a plurality of groups, and the support rods 532 are provided with two groups. The two groups of support rods 532 penetrate through the plurality of groups of defogger plates 531. The plurality of groups of defogger plates 531 are provided at the upper end of the spray tower 5 through the two groups of support rods 532. The present invention is provided with a flow detector in the connecting cavity 14. During operation, the flow detector is used to detect the flow rate of the exhaust gas entering the spray tower 5 per unit time. The defogger plate 531 in the present invention includes a first bracket 5311 and a second bracket 5312. The second bracket 5312 is fixedly mounted Installed on the support rod 532, the first bracket 5311 is movably installed inside the second bracket 5312, and the upper and lower ends of the first bracket 5311 and the second bracket 5312 are provided with second electromagnets 5313. The staff can control the movement of the first bracket 5311 in the second bracket 5312 through two groups of second electromagnets 5313, and then adjust the spacing of several groups of defogger plates 531 in real time according to the flow rate of exhaust gas, on the one hand, to avoid the large spacing of several groups of defogger plates 531 and low efficiency in removing droplets, and on the other hand, to prevent the spacing of several groups of defogger plates 531 from being too small, which leads to increased energy consumption.

[0034] like Figure 9-10 As shown, a plurality of exhaust holes are arranged on the first bracket 5311, and sealing gaskets are arranged in the contact areas between the first bracket 5311, the second bracket 5312 and the support rod 532. During operation of the present invention, if droplets gather between the two groups of defogger plates 531, the first bracket 5311 can be made to circulate in the second bracket 5312 through the two groups of second electromagnets 5313. At this time, the exhaust holes will intermittently discharge a group of gas, so as to avoid droplets clogging the areas between the plurality of defogger plates 531, and ensure that the exhaust gas can flow smoothly between the plurality of defogger plates 531.

[0035] Working principle of the present invention: The principle of solid-phase converter oxidation method involves solid-phase reaction and converter oxidation process. Solid-phase reaction refers to the generation of new substances by chemical reaction of two or more substances. The microscopic process is that the reactant molecules or ions contact and react to generate new substances. In solid-phase reaction, the reactants are usually mixed in powder form and diffuse in the crystal lattice through the contact surface of the particles to react. The diffusion rate is the key factor determining the reaction speed and degree. The converter oxidation process is a specific solid-phase reaction application, in which steel slag is solid-phase oxidized and modified in a converter. The method includes placing the steel slag in a high-temperature environment, introducing synthetic air for oxidation, so as to complete the transformation of non-magnetic ferrous oxide and magnesium oxide in the steel slag into magnetic iron-rich phase aggregation, and evaluating the oxidation modification results by magnetic separation.

[0036] Before work, the air collecting pipe 3 is connected to the potassium permanganate production room. During work, the exhaust gas in the potassium permanganate production room is sucked out by the fan 7. At this time, the exhaust gas will flow along the air collecting pipe 3-purification chamber 12-connecting chamber 14-inlet pipe 2-spray tower 5-exhaust pipe 6. The aggregate assembly arranged in the purification chamber 12 can collect the particulate matter in the exhaust gas for treatment, and at the same time achieve the purpose of preliminary purification. The alkaline solution is continuously input into the spray pipe 52 through the liquid pump 16 to remove the acidic gas in the exhaust gas. The filler assembly 51 ensures that the exhaust gas can fully react with the alkaline solution. The demisting mechanism 53 removes the droplets in the exhaust gas to prevent the exhaust gas from carrying more droplets into the fan 7 after purification. The demisting plate 531 in the present invention includes a first bracket 5311 and a second bracket 5312. The staff can control the first bracket 5311 in the second bracket 531 through two sets of second electromagnets 5313 2, and then adjust the spacing of several groups of defogger plates 531 in real time according to the flow rate of exhaust gas. If droplets gather between the two groups of defogger plates 531, the two groups of second electromagnets 5313 can also make the first bracket 5311 circulate in the second bracket 5312. At this time, the exhaust hole will intermittently discharge a group of gas to avoid droplets blocking the area between several groups of defogger plates 531. The packing assembly 51 in the present invention includes a first packing tray 511 and a second packing tray 512. The staff can drive several groups of first packing trays 511 and several groups of second packing trays 512 to move in the spray tower 5 through several groups of linear drive assemblies 43, so as to facilitate the staff to timely adjust the height of the packing assembly 51 according to the flow rate of the exhaust gas and the flow rate of the alkaline solution, and then ensure that the alkaline solution stays in the packing layer for a long enough time on the basis of ensuring that the alkaline solution passes through the packing assembly 51 smoothly.

[0037] Although the embodiments of the present invention have been shown and described, it is to be understood that the above embodiments are illustrative and are not to be construed as limitations on the present invention. A person skilled in the art may change, modify, substitute and vary the above embodiments within the scope of the present invention without departing from the principles and purpose of the present invention.
