Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of manganese slag treatment and recovery, and particularly relates to a recovery device for nitrogen and sulfur recovery in manganese slag treatment. BACKGROUND

[0002] Manganese slag is a solid waste produced in the process of electrolytic manganese, which may contain a certain amount of nitrogen and sulfur elements. The recovery of nitrogen and sulfur from the manganese slag has both environmental and economic significance. The nitrogen in the manganese slag may exist in the form of ammonium salt, etc. When the manganese slag is treated, it is put into a liquid, and then the ammonia nitrogen oxide in the solution is converted into nitrogen gas under the action of chlorine gas by the breakpoint chlorination method.

[0003] In the prior art, when the breakpoint chlorination method is used for treatment, chlorine gas is directly introduced into the manganese slag solution, and then the chlorine gas is dissolved in the liquid. The chlorine gas in the liquid reacts with the ammonia nitrogen oxide. In this way, the contact area between the chlorine gas and the ammonia nitrogen oxide is small, the treatment efficiency is low, and the chlorine gas cannot be completely dissolved in the solution, which causes part of the chlorine gas to escape into the air, polluting the air. The nitrogen gas generated in the manganese slag solution is easy to drive the chlorine gas out during the discharge process, thereby causing harm to the atmosphere. SUMMARY

At this time, the control valve opens, and chlorine gas is sprayed out through several second through holes to react with the solution mist in the second fixed body, converting the ammonia nitrogen oxides in the mist into nitrogen gas. The mist in the shaking state can greatly increase the contact speed with chlorine gas, thereby improving the processing efficiency.

[0017] 2. When nitrogen passes through the filter screen in the horizontal section of the first conveying hole, a small amount of chlorine gas rising under the influence of nitrogen gas passes through the filter screen.

Under the action of gravity, the chlorine solution flows back into the second fixed body through several first through holes. This not only prevents chlorine gas from escaping and harming the air, but also allows for the recycling of water, improving the safety of the device while reducing costs.

[0030] The opening structure of the fixed pipe 313 is threadedly connected to the side of the gas supply pipe 33. The lower end of the gas supply pipe 33 is provided with a second slot 39. The side of the gas supply pipe 33 is provided with several sets of third through holes 312 communicating with the second slot 39. The gas supply pipe 33 is fixedly connected to a fixed rod 36 in each of the several third through holes 312. A control valve 311 is fixedly connected to each of the several fixed rods 36.

[0031] Several groups of the third through holes 312 are opened on the side of the gas transmission pipe 33 in an equidistant manner, and each group of the third through holes 312 consists of four third through holes 312 arranged in a circle.

[0032] The inner sides of several fixed rods 36 are respectively connected to the second slot 39, and several second through holes 310 are respectively opened through the sides of several fixed rods 36. A first one-way valve is respectively provided in several second through holes 310.

[0033] The main body 1 is rotatably connected to a second fixing body 32 in the first placement groove 31. The upper end of the second fixing body 32 is provided with a first empty groove 35. The lower end of the second fixing body 32 is an open structure. The lower end of the second fixing body 32 is fixedly connected to the outer side of the fixing tube 313. The lower end of the second fixing body 32 is provided with a cylindrical second cavity 314. Several vibrating plates are fixedly connected to the lower end of the second fixing body 32.

[0034] The upper end of the second fixing body 32 is provided with a plurality of filter holes 315, which are arranged in a semi-circular distribution. The second fixing body 32 is rotatably connected to a cover plate 316 with a semi-circular ring structure in the second cavity 314. The inner side of the cover plate 316 is provided with a third placement groove 317, and the outer side of the fixing tube 313 is provided with a fourth placement groove 318. An electric telescopic rod 319 is fixedly connected to the cover plate 316 in the third placement groove 317. The telescopic end of the electric telescopic rod 319 is fixedly connected to a limiting body 320 that slides with the fourth placement groove 318.

[0035] The main body cylinder 1 has a fourth cavity 325 that communicates with the first placement groove 31. A second motor 327 is fixedly connected to the main body cylinder 1 in the fourth cavity 325. A gear 326 is fixedly connected to the transmission shaft end of the second motor 327. A toothed ring 328 that meshes with the gear 326 is fixedly connected to the side of the second fixing body 32.

[0036] The lower end of the fixed tube 313 is provided with several fourth through holes 321, and the lower end of the main body tube 1 is provided with several fifth through holes 324 communicating with the third cavity 322. The main body tube 1 is provided with a second one-way valve in each of the several fifth through holes 324. The fifth through holes 324 are connected to the chlorine tank through pipes. The side of the main body tube 1 is provided with a second placement groove 37 near the lower end. The main body tube 1 is fitted with a protective ring 38 in the second placement groove 37.

[0037] Specifically, the oscillating plate on the lower end face of the second fixed body 32 is activated, causing the manganese slag solution to agitate into a mist. The mist then rises, and chlorine gas enters the fixed pipe 313 through the fourth through hole 321. Subsequently, the chlorine gas enters several fixed rods 36 through the gas supply pipe 33. At this time, the control valve 311 is opened, and chlorine gas is sprayed out through several second through holes 310, reacting with the solution mist in the second fixed body 32 to convert ammonia nitrogen oxides in the mist into nitrogen gas. The agitated mist can significantly increase the contact speed with chlorine gas, thereby improving the processing efficiency.

[0038] In this embodiment, a chlorine gas escape prevention mechanism 2 is provided at the upper end of the main body cylinder 1.

[0039] The chlorine gas escape prevention mechanism 2 includes a threaded groove 21 formed on the upper end of the main body cylinder 1. A connecting ring 23 is fitted inside the threaded groove 21 on the main body cylinder 1. A first fixing body 22 is fixedly connected to the upper end of the connecting ring 23. Four first conveying holes 24 are formed at equal angles on the upper end of the first fixing body 22. A filter screen 25 is fixedly connected to the horizontal section of the first conveying hole 24 on the first fixing body 22. A plurality of first through holes 26 are formed at equal intervals on the lower end of the first fixing body 22 at positions corresponding to the filter screen 25. The upper ends of the plurality of first through holes 26 communicate with the first conveying holes 24.

[0040] An air inlet 4 is provided through the upper end of the first fixed body 22. A third one-way valve is provided in the air inlet 4 of the first fixed body 22. Chlorine detectors are provided in the vertical sections of the four first delivery holes 24 of the first fixed body 22.

[0041] Specifically, when nitrogen passes through the filter screen 25 in the horizontal section of the first conveying hole 24, a small amount of chlorine gas rising under the influence of nitrogen passes through the filter screen 25. At this time, water mist will condense inside the filter screen 25, and the chlorine gas will dissolve in the solution on the surface of the filter screen 25. Under the action of gravity, the chlorine solution flows back into the second fixed body 32 through several first through holes 26. This prevents chlorine gas from escaping and harming the air while allowing water to be recycled.

[0042] In use, place the main body cylinder 1 on a perforated tabletop. Then, connect a flexible hose to the outlet of the chlorine cylinder, with the other end of the hose connected to the fifth through hole 324. The electric telescopic rod 319 extends, causing the limiting body 320 to move into the fourth placement slot 318. Then, the first motor 323 drives the cover plate 316 to rotate below the filter hole 315 via the fixed pipe 313. Next, pour the manganese slag solution into the first empty slot 35. Start the second motor 327, which drives the gear 326 to rotate. The gear 326, in turn, drives the gear ring 328 to rotate, which in turn drives the second fixed body 32 to rotate. The second fixed body 32 agitates the internal solution. Simultaneously, the vibrating plate on the lower end of the second fixed body 32 is activated, causing the manganese slag solution to agitate into a mist. The mist then rises, and chlorine gas enters the fixed pipe 313 through the fourth through hole 321. Subsequently, the chlorine gas enters several fixed rods 36 through the gas delivery pipe 33. At this time, the control valve 311 opens, and chlorine gas is ejected through several second through holes 310, reacting with the solution mist in the second fixed body 32 to convert ammonia nitrogen oxides in the mist into nitrogen gas. The agitated mist can significantly increase the contact speed with chlorine gas, thereby improving the processing efficiency.

[0043] Since the nitrogen gas after the reaction is less dense than air, it rises into the first conveying hole 24. Then, the nitrogen gas passes through the filter screen 25 in the horizontal section of the first conveying hole 24. When a small amount of chlorine gas rises under the influence of nitrogen gas and passes through the filter screen 25, water mist will condense inside the filter screen 25. At the same time, the chlorine gas will dissolve in the solution on the surface of the filter screen 25. Under the action of gravity, the chlorine solution flows back into the second fixed body 32 through several first through holes 26. This not only prevents chlorine gas from escaping and harming the air, but also allows for the recycling of water, improving the safety of the device while reducing costs.

[0044] After the ammonia and nitrogen oxides in the manganese slag solution have completely reacted, the switch of the chlorine tank is turned off and the first motor 323 is started. The first motor 323 drives the cover plate 316 to rotate, so that the cover plate 316 rotates to a region that does not overlap with the filter hole 315. At this time, the reacted solution enters the first cavity 34 and is finally discharged through the second placement tank 37. At the same time, the first fixing body 22 is opened to pour out the solid impurities.

[0045] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of the invention.
