Description

Technical Field

[0001] The invention relates to the technical field of dechlorination wastewater recovery, and more specifically to a desulfurization gypsum dechlorination wastewater recovery device. Background Art

[0002] Desulfurized gypsum is also called flue gas desulfurized gypsum and sulfur gypsum. Its main component is calcium sulfate dihydrate, which is the same as natural gypsum. When producing desulfurized gypsum, lime-limestone is ground into slurry, and the flue gas containing sulfur dioxide after dust removal is passed through a slurry scrubber to remove sulfur dioxide. The lime slurry reacts with sulfur dioxide to form calcium sulfate and calcium sulfite. Calcium sulfite is oxidized and converted into calcium sulfate to obtain industrial by-product gypsum, which is called desulfurized gypsum and is widely used in building materials and other industries.

[0003] When desulfurized gypsum is prepared, the chloride ion content in desulfurized gypsum often exceeds the standard. Therefore, desulfurized gypsum needs to be dechlorinated during preparation. After dechlorination, dechlorinated wastewater will be generated. The dechlorinated wastewater contains a high concentration of chloride ions. When the wastewater is used again, the excessive chloride ions will affect the desulfurization efficiency, reduce the quality of gypsum, and cause the corrosion of equipment to increase. Therefore, the dechlorinated wastewater needs to be recycled and treated;

[0004] When recycling desulfurized gypsum dechlorination wastewater, ammonia water is first added to adjust the wastewater to neutrality, and then a dechlorinating agent is added to the neutral solution. At this time, a chlorine-containing precipitate is formed, and the formed chlorine-containing precipitate is separated. The upper liquid can be recycled and reused. However, when the wastewater is adjusted to neutrality, the ammonia water and the wastewater cannot be mixed evenly, so that the wastewater is not in a neutral state during precipitation. If the ammonia water and the wastewater are mixed evenly, a lot of working time will be wasted;

[0005] When a neutral solution is formed into a chlorine-containing precipitate, the neutral solution and the dechlorinating agent must first be mixed evenly. After the mixing is evenly carried out, the solution is allowed to stand and precipitate, which wastes a lot of time. In addition, mixing work is required during the precipitation process, thereby reducing the overall recovery efficiency. Summary of the invention

DETAILED DESCRIPTION

[0028] The technical scheme of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the present invention. In addition, the forms of the various structures recorded in the following embodiments are only examples. The desulfurization gypsum dechlorination wastewater recovery equipment involved in the present invention is not limited to the various structures recorded in the following embodiments. All other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention.

[0029] Reference Figure 1 and Figure 2The present invention provides a desulfurized gypsum dechlorination wastewater recovery device, comprising a wastewater inlet pipe 1, an acid-base neutralization mechanism 2 is fixedly connected to the side of the wastewater inlet pipe 1, a connecting pipe 3 is fixedly connected to the side of the acid-base neutralization mechanism 2 away from the wastewater inlet pipe 1, a sedimentation mechanism 4 is fixedly connected to the side of the connecting pipe 3 away from the acid-base neutralization mechanism 2, a drainage pipe 5 is fixedly connected to the side of the sedimentation mechanism 4, a dechlorinating agent pipe 6 is fixedly connected to the top of the sedimentation mechanism 4, a mud discharge pipe 7 is fixedly connected to the top of the sedimentation mechanism 4 away from the side of the connecting pipe 3, the bottom end of the sedimentation mechanism 4 is conical, and the bottom end of the mud discharge pipe 7 is located at the bottom of the cone of the bottom end of the sedimentation mechanism 4, and the drainage pipe 5 is located at the top of the side of the sedimentation mechanism 4.

[0030] In the embodiment of the present application, the sedimentation mechanism 4 will carry out sedimentation. After the sedimentation, the sedimentation product will accumulate at the bottom of the sedimentation mechanism 4, and the bottom of the sedimentation mechanism 4 is set to a cone, which is convenient for sedimentation and accumulation. The accumulated sediment can be pumped away through the mud discharge pipe 7. Therefore, the bottom end of the mud discharge pipe 7 is located at the bottom of the cone at the bottom of the sedimentation mechanism 4, which is convenient for the mud discharge pipe 7 to pump away the sediment. The upper part of the sedimentation mechanism 4 is clean and recyclable liquid, which is recovered through the drain pipe 5 located at the top. At this time, the liquid recovered by the drain pipe 5 is relatively clean.

[0031] Reference Figure 3 , Figure 4 , Figure 5 as well as Figure 6 The acid-base neutralization mechanism 2 includes a connecting channel 201 for liquid circulation, a servo motor 202 is fixedly connected to the top of the connecting channel 201, a motor output shaft 203 is fixedly connected to the bottom of the servo motor 202, a first bevel gear 204 is fixedly connected to the bottom of the motor output shaft 203, a second bevel gear 205 is meshed with the bottom end of the side of the first bevel gear 204, an ammonia passing pipe 206 is fixedly connected to the side of the second bevel gear 205 away from the first bevel gear 204, an ammonia passing pipe 206 is fixedly connected to the side of the ammonia passing pipe 206, an ammonia discharging plate 207 is fixedly connected, and a sealing connecting ring 209 is movably sleeved on the side of the ammonia passing pipe 206 close to the second bevel gear 205. The top of 209 is fixedly connected with an ammonia adding channel 208, and a liquid channel is opened in the ammonia passing tube 206. The ammonia in the ammonia adding channel 208 can enter the liquid channel of the ammonia passing tube 206 through the connecting groove at the top of the sealing connecting ring 209, and the liquid in the liquid channel of the ammonia passing tube 206 can be discharged through the discharge hole on the side of the ammonia discharge plate 207. Four through grooves are opened on the side of the ammonia passing tube 206 where the sealing connecting ring 209 is located, and the four through grooves connect the liquid channel in the ammonia passing tube 206 with the connecting groove at the top of the sealing connecting ring 209. When the ammonia passing tube 206 rotates, the sealing connecting ring 209 seals the through groove on the side of the ammonia passing tube 206.

[0032] In the embodiment of the present application, when the second bevel gear 205 rotates, the ammonia discharge plate 207 is driven to rotate through the ammonia passing tube 206. The ammonia in the ammonia adding channel 208 can enter the liquid channel of the ammonia passing tube 206 through the connecting groove at the top of the sealing connecting ring 209. Therefore, as the ammonia passing tube 206 rotates, the ammonia enters the ammonia discharge plate 207 and is discharged through the discharge hole on the side of the ammonia discharge plate 207. When the ammonia discharge plate 207 is discharging ammonia, it will rotate to mix the ammonia with the wastewater. Evenly, and when the ammonia water is discharged through multiple discharge holes, it will have a mixing effect, and the rotation of the ammonia water discharge plate 207 itself can further improve the mixing effect. Four through grooves are provided on the side of the ammonia water passing tube 206 where the sealing connection ring 209 is located. Therefore, when the connecting groove above the sealing connection ring 209 is connected to the ammonia water, no matter how the ammonia water passing tube 206 rotates, ammonia water will enter the ammonia water passing tube 206 to ensure the smooth progress of the mixing process. The present application can mix ammonia water and wastewater evenly in a short time.

[0033] Reference Figure 4 and Figure 5 The side of the bottom end of the first bevel gear 204 away from the second bevel gear 205 is meshed with a third bevel gear 210, and the side of the third bevel gear 210 away from the first bevel gear 204 is fixedly connected to a mixing blade 211, the inside of the connecting channel 201 is fixedly connected to a fixing plate 213, and the side of the fixing plate 213 away from the connecting channel 201 is fixedly connected to a sealing box 212, and the first bevel gear 204, the second bevel gear 205 and the third bevel gear 210 are all located inside the sealing box 212.

[0034] In the embodiment of the present application, the mixing blade 211 will mix the ammonia water and the wastewater mixed by the ammonia water discharge plate 207 again to ensure that the ammonia water and the wastewater are evenly mixed to become a neutral solution. Therefore, the present application is provided with two mixing processes between the ammonia water and the wastewater to ensure the mixing effect, thereby ensuring that the neutral solution finally produced will not be acidic or alkaline. The stirring process of the present application coincides with the flow process of the wastewater, without wasting time, thereby improving the overall recovery efficiency of the wastewater. The sealing box 212 can protect the first bevel gear 204, the second bevel gear 205 and the third bevel gear 210 to prevent the first bevel gear 204, the second bevel gear 205 and the third bevel gear 210 from being damaged in the wastewater.

[0035] Reference Figure 7 and Figure 8The precipitation mechanism 4 includes a chlorine-containing precipitation cylinder 401 for precipitation, the top of the chlorine-containing precipitation cylinder 401 is fixedly connected to a sealing cover plate 402, the top of the sealing cover plate 402 is fixedly connected to a stirring motor 403, the bottom of the stirring motor 403 is fixedly connected to a stirring shaft 404, the side of the stirring shaft 404 is fixedly connected to a stirring blade 405, the bottom of the sealing cover plate 402 is fixedly connected to a central inner cylinder 406, the stirring blade 405 is located inside the central inner cylinder 406, and the liquid in the stirring motor 403 directly flows into the stirring shaft 404. Into the central inner tube 406, the side of the central inner tube 406 away from the connecting pipe 3 is fixedly connected to the side of the dechlorination agent tube 6, the inside of the chlorine-containing sedimentation tube 401 is fixedly connected with a support rod 408, the support rod 408 is fixedly connected to the inside of the chlorine-containing sedimentation tube 401 away from the chlorine-containing sedimentation tube 401 with a water flow buffer table 407, the top of the water flow buffer table 407 is provided with a conical groove, the bottom end of the central inner tube 406 is located in the conical groove of the water flow buffer table 407, and a distance of five centimeters is left between the bottom end of the central inner tube 406 and the water flow buffer table 407.

[0036] In the embodiment of the present application, the neutral solution directly enters the central inner cylinder 406 through the connecting pipe 3, and the dechlorinating agent enters the central inner cylinder 406 through the dechlorinating agent pipe 6. Therefore, the neutral solution and the dechlorinating agent will contact in the central inner cylinder 406, and will not directly enter the chlorine-containing precipitation cylinder 401. When the stirring blade 405 rotates, the dechlorinating agent and the neutral solution are mixed. The evenly mixed dechlorinating agent and the neutral solution flow downward to the bottom of the conical groove in the water flow buffer table 407. Therefore, the mixed liquid will not directly enter the chlorine-containing precipitation cylinder 401, but will enter the conical groove of the water flow buffer table 407. Therefore, the water flow buffer table 407 can buffer the liquid to avoid liquid The body causes the solution being precipitated in the chlorine-containing sedimentation cylinder 401 to be stirred, and the bottom end of the central inner cylinder 406 is located at the bottom end of the conical groove in the water flow buffer platform 407, so that the liquid slowly flows out of the water flow buffer platform 407, ensuring that the liquid in the chlorine-containing sedimentation cylinder 401 will not be greatly stirred, thereby improving the sedimentation effect, and a distance of five centimeters is left between the bottom end of the central inner cylinder 406 and the water flow buffer platform 407, so that the liquid can enter the chlorine-containing sedimentation cylinder 401 from the central inner cylinder 406, and the support rod 408 will support the water flow buffer platform 407, so that the water flow buffer platform 407 can still maintain a relatively stable state when impacted by the liquid in the central inner cylinder 406.

[0037] The working principle of the present invention is as follows: wastewater enters into the wastewater inlet pipe 1. When wastewater enters into the wastewater inlet pipe 1, the servo motor 202 is started. After the servo motor 202 is started, the first bevel gear 204 is driven to rotate through the motor output shaft 203. When the first bevel gear 204 rotates, the second bevel gear 205 is driven to rotate. When the second bevel gear 205 rotates, the ammonia discharge plate 207 is driven to rotate through the ammonia passing tube 206. At this time, ammonia enters into the ammonia adding channel 208. After passing through the ammonia adding channel 208 and the sealing connecting ring 209, the ammonia enters into the ammonia passing tube 206. As the ammonia passing tube 206 rotates, the ammonia enters into the ammonia discharge plate 207 and is discharged through the discharge holes on the side of the ammonia discharge plate 207. When discharging ammonia, the ammonia discharge plate 207 will rotate to mix the ammonia with the wastewater evenly. The ammonia contacts the wastewater through a plurality of discharge holes, so as to facilitate the even mixing between the ammonia and the wastewater.

[0038] When the ammonia discharge plate 207 mixes the ammonia and the wastewater, the first bevel gear 204 drives the second bevel gear 205 to rotate, and at the same time drives the third bevel gear 210 to rotate. When the third bevel gear 210 rotates, it drives the mixing blade 211 to rotate. Therefore, the ammonia and the wastewater mixed by the ammonia discharge plate 207 will be mixed again by the mixing blade 211. At this time, the mixing blade 211 mixes the ammonia and the wastewater evenly to become a neutral solution.

[0039] The neutral solution enters the central inner tube 406 through the connecting pipe 3, and the dechlorinating agent enters the central inner tube 406 through the dechlorinating agent pipe 6. The stirring motor 403 drives the stirring blade 405 to rotate through the stirring shaft 404. When the stirring blade 405 rotates, the dechlorinating agent and the neutral solution are mixed. The evenly mixed dechlorinating agent and the neutral solution flow downward to the bottom end of the conical groove in the water flow buffer table 407. At this time, they rise at the bottom end of the water flow buffer table 407 and slowly flow from the top of the water flow buffer table 407 to the chlorine-containing sedimentation cylinder 401. The dechlorinating agent and the neutral solution entering the chlorine-containing sedimentation cylinder 401 will precipitate, and the precipitated product falls to the bottom of the chlorine-containing sedimentation cylinder 401 and is extracted through the mud discharge pipe 7. The clean liquid on the upper layer is extracted through the drain pipe 5 and is recycled again.
