Description

Technical Field

[0001] The invention relates to the technical field of high-salt fly ash treatment, and in particular to a high-salt fly ash resource treatment device. Background Art

[0002] High-salt fly ash refers to fly ash produced when burning materials containing high salt content. Fly ash is fine particles produced during the combustion process and is usually discharged into the atmosphere with flue gas. High-salt fly ash is named because it contains a higher concentration of salt substances such as sodium chloride, sodium sulfate, etc. The high-salt fly ash resource treatment device is a device specially used to treat and utilize high-salt fly ash. This device is designed to reduce the potential negative impact of high-salt fly ash on the environment, while turning it into treasure and extracting reusable resources.

[0003] Currently, in the process of municipal waste incineration, since residents' domestic waste contains a large amount of salt-containing substances, such as table salt in kitchen waste, some chlorine-containing plastics, etc., when these wastes are incinerated, chlorine elements will exist in fly ash in various forms, and then as the flue gas cools, part of it will condense on the surface of fly ash particles, including sodium chloride. In order to realize the recycling of resources in high-salt fly ash, workers often extract the salt in high-salt fly ash by first washing with water and then evaporating it. In the process of treating high-salt fly ash, in order to ensure that the salt in the fly ash is fully extracted and further improve the extraction rate of salt, it is often not only washed once, because it is difficult to completely extract the salt in the fly ash in one washing. The method of multiple input of external water source washing will be adopted to further improve the extraction efficiency of salt in fly ash, but this multiple washing method will cause the water consumption to increase exponentially. New water needs to be added for each washing, thereby generating a large amount of washing wastewater, which in turn causes a waste of water resources.

The outer surface of the return pipe 411 is provided with a second solenoid valve 412. The top of the gas tank 401 is provided with a pressure sensor 413. The top of the bottom plate 1 is fixedly connected to the bottom of the support frame 414. The top of the output pipe 403 is fixedly penetrated into the interior of the gas tank 401. The bottom end of the input pipe 405 is fixedly penetrated into the interior of the pressurizing chamber 406. The top of the return pipe 411 is fixedly penetrated into the interior of the water tank 203. The outer surface of the gas tank 401 A storage component 5 is arranged on the surface, and the storage component 5 includes a storage tank 503 for storing high-concentration salt water. The outer surface of the storage tank 503 is fixedly connected with a pipe 504. The outer surface of the pipe 504 is provided with a one-way valve 505 for preventing the backflow of high-concentration salt water. The top of the pipe 504 passes through the interior of the gas tank 401. The outer surface of the gas tank 401 is fixedly connected with a guide pipe 501 near the bottom end. The bottom end of the guide pipe 501 is fixedly passed through the interior of the pressurizing chamber 406. The outer surface of the guide pipe 501 is provided with a third solenoid valve 502.

[0033] In this embodiment, when the water containing salt completely enters the pressurized chamber 406, the fifth solenoid valve 216 is closed, the air pump 402 is started, and the output pipe 403 is driven to extract argon gas into the gas tank 401. The gas enters the pressurized chamber 406 through the input pipe 405, and the piston 408 is pushed forward along the inner wall of the pressurized chamber 406 under the action of strong pressure. Figure 7As shown, the limiting frame 407 limits the piston 408, preventing the piston 408 from moving to a position in contact with the inner wall of the pressurized chamber 406. The movement of the piston 408 pushes the salt water in the pressurized chamber 406 forward, and the water in the salt water passes through the semipermeable membrane body 410 under the action of pressure. The pore size of the semipermeable membrane body 410 is small enough to only allow water molecules to pass through, but not salt ions such as Na+ and Cl-. The surface of the semipermeable membrane body 410 has different hydrophilicity, which affects its interaction with water molecules. Hydrophilic materials will more easily adsorb and conduct water molecules. When the semipermeable membrane body 410 separates the salt water and the pure water, due to the concentration difference, the water molecules will pass through the semipermeable membrane body 410 from the side with low salt concentration. The process of migration to the side with high salt concentration is called osmosis. Osmosis is a natural selection, which makes the system reach a state of equilibrium. Since the salt in the salt water cannot pass through the semipermeable membrane body 410, the salt in the water can only be retained on the other side of the semipermeable membrane body 410. At the same time, the second solenoid valve 412 is opened, so that the pressurizing chamber 406 is connected with the return pipe 411, and then the salt-free water source that passes through the semipermeable membrane body 410 enters the interior of the water tank 203 again through the return pipe 411, thereby realizing water recovery and purification of the salt in the water. When the water source that passes through the semipermeable membrane body 410 is basically completely transported to the interior of the water tank 203, the second solenoid valve 412 is closed. In addition, when the piston 408 is under the action of air pressure, When it moves down to the side close to the mounting bracket 409, the gas tank 401 is in a negative pressure state due to the continuous output of gas. When the salt purification in the pressurizing chamber 406 is completed, the air pump 402 is closed, and the first solenoid valve 404 is closed at the same time, and then the third solenoid valve 502 is opened. At this time, since the interior of the pressurizing chamber 406 is in a high pressure state, the interior of the gas tank 401 is in a negative pressure state, and the pressure sensor 413 is opened at the same time to detect the pressure in the gas tank 401. When the pressure in the gas tank 401 is insufficient, the air pump 402 is started again to extract the gas in the gas tank 401 until the pressure in the gas tank 401 reaches the required value. Among them, the pressure sensor 413 uses the characteristic that the resistance of the material changes with the pressure. When pressure is applied, The tiny deformation causes the resistance to change. By measuring the resistance change, the pressure applied to the sensor can be calculated. When the guide pipe 501 connects the gas tank 401 and the pressurized chamber 406, the high-concentration salt water in the pressurized chamber 406 can enter the gas tank 401 through the guide pipe 501 under the action of the pressure difference. When the high-concentration salt water is transported to the gas tank 401, the third solenoid valve 502 is closed and the one-way valve 505 is opened. The one-way valve 505 is a valve that allows the fluid to flow in only one direction and prevents the reverse flow. Its working principle is mainly based on the fluid pressure difference. In the static state or when the flow direction is not satisfied, the valve flap is usually in a closed state to prevent the fluid from flowing. At this time, the valve flap relies on the action of gravity.Sealed on the valve seat, when the fluid pressure is applied to the valve disc from the inlet of the valve, if this pressure is greater than the pressure above the valve disc, the valve disc will overcome the reaction force of its gravity and open, thereby allowing the fluid to flow through the valve. Once the flow direction changes, or the pressure of the fluid is lower than the pressure above the valve disc, the valve disc will close due to gravity and seal on the valve seat, thereby preventing the fluid from flowing in the opposite direction, so that the high-concentration salt water in the gas tank 401 enters the storage tank 503 through the pipeline 504 for internal storage, and then the fourth solenoid valve 205 can be opened again to transport the water source in the water tank 203 to the interior of the warehouse body 201 again to continue to extract the salt in the high-salt fly ash. By recycling the water, water resources are saved, and the problem of consuming a large amount of water resources and wasting resources in the process of extracting salt from high-salt fly ash in the prior art is solved.

A spiral blade 208 for mixing fly ash is arranged inside the silo 201. A leakage hole cylinder 209 is fixedly installed between the opposite inner walls of the silo 201. The spiral blade 208 is arranged inside the leakage hole cylinder 209. A slide groove 210 is opened on the inner wall of the silo 201 near the discharge port. A pressure-resistant frame 211 is fixedly installed on the outer surface of the silo 201 near the bottom. A hydraulic rod 212 is arranged on the inner wall of the pressure-resistant frame 211. A baffle 213 is fixedly installed on one end of the hydraulic rod 212. A waterproof ring 214 is arranged on the outer surface of the baffle 213. The outer surface of the baffle 213 slides with the inner wall of the slide groove 210. A connecting pipe 215 is fixedly connected to the bottom of the silo 201 near the center. The bottom end of the connecting pipe 215 is fixedly penetrated to the inside of the pressurized bin 406. A fifth solenoid valve 216 is arranged on the outer surface of the connecting pipe 215.

[0035] In this embodiment, during the process of recycling high-salt fly ash, a certain amount of high-salt fly ash is first fed through the feed bin 202 along the leak tube 209 to the surface of the spiral blade 208, wherein Figure 4As shown, the leakage hole cylinder 209 is connected with the feed bin 202, and its purpose is to prevent the material from entering between the bin body 201 and the outer surface of the leakage hole cylinder 209, and then the forward and reverse motor 206 is started to drive the spiral shaft 207 to rotate, and then drive the spiral blade 208 to rotate, so that the material entering the feed bin 202 is transported and stirred along the bin body 201 through the spiral blade 208. At the same time, the fourth electromagnetic valve 205 is opened, so that the water source in the water tank 203 enters the interior of the bin body 201 through the conveying pipe 204, and then contacts the fly ash along the leakage hole cylinder 209, so that the fly ash and water are stirred and mixed under the drive of the spiral blade 208. Since the salt in the high-salt fly ash has good solubility in water, when the high-salt fly ash is mixed with water, the water molecules will surround the salt ions to form a solution. Liquid, which means that salt will dissolve from solid fly ash into water, thereby realizing the separation between salt and high-salt fly ash. When the material is transferred to the side close to the forward and reverse motor 206, the forward and reverse motor 206 is started again to drive the spiral blade 208 to rotate in the opposite direction, thereby driving the material to be transported and stirred in the opposite direction along the bin body 201. When the high-salt fly ash is mixed, the fifth solenoid valve 216 is opened, so that the water source with salt in the material is output along the small hole in the leakage tube 209, and flows out through the connecting pipe 215 into the interior of the pressurized bin 406, wherein the aperture of the leakage tube 209 can only penetrate the water source, and the high-salt fly ash cannot seep out of the leakage tube 209.

When the high-salt fly ash is mixed, the fifth solenoid valve 216 is opened, so that the water source with salt in the material is output along the small hole in the leakage tube 209, and flows out through the connecting pipe 215 to the inside of the pressurized bin 406, wherein the aperture of the leakage tube 209 can only penetrate the water source, and the high-salt fly ash cannot seep out of the leakage tube 209. The high-salt fly ash and water are driven by the stirring component 2 to be mixed, stirred and transported. When the water containing salt completely enters the pressurized bin 406, the fifth solenoid valve 216 is closed, and the air pump 402 is started to drive the output pipe 403 to extract argon gas into the gas tank 401. The gas enters the inside of the pressurized bin 406 through the input pipe 405, and pushes the piston 408 to be transported forward along the inner wall of the pressurized bin 406 under the action of strong pressure. Figure 7As shown, the limiting frame 407 limits the piston 408, preventing the piston 408 from moving to a position in contact with the inner wall of the pressurizing chamber 406. The movement of the piston 408 pushes the salt water in the pressurizing chamber 406 forward, and the water in the salt water passes through the semipermeable membrane body 410 under the action of pressure. Since the salt in the salt water cannot pass through the semipermeable membrane body 410, the salt in the water can only be retained on the other side of the semipermeable membrane body 410. At the same time, the second solenoid valve 412 is opened, so that the pressurizing chamber 406 is connected to the return pipe 411, and the salt-free water source that passes through the semipermeable membrane body 410 enters the interior of the water tank 203 again through the return pipe 411. When the water source that passes through the semipermeable membrane body 410 is basically completely transported After reaching the inside of the water tank 203, the second solenoid valve 412 is closed. In addition, when the piston 408 moves to the side close to the mounting bracket 409 under the action of air pressure, the gas tank 401 is in a negative pressure state due to the continuous output of gas. When the salt purification in the pressurized chamber 406 is completed, the air pump 402 is closed, and the first solenoid valve 404 is closed at the same time, and then the third solenoid valve 502 is opened. At this time, since the interior of the pressurized chamber 406 is in a high pressure state, and the interior of the gas tank 401 is in a negative pressure state, the pressure sensor 413 is opened at the same time to detect the pressure in the gas tank 401. When the pressure in the gas tank 401 is insufficient, the air pump 402 is started again to extract the gas in the gas tank 401 until the pressure in the gas tank 401 reaches the required value. When the guide pipe When the gas tank 401 is connected to the pressurized chamber 406 by means of the pressure difference, the high-concentration salt water in the pressurized chamber 406 can enter the interior of the gas tank 401 through the guide pipe 501. When the high-concentration salt water is completely transported to the interior of the gas tank 401, the third solenoid valve 502 is closed and the one-way valve 505 is opened, so that the high-concentration salt water in the gas tank 401 can enter the interior of the storage tank 503 through the pipeline 504 for storage. Then, the fourth solenoid valve 205 can be opened again to transport the water source in the water tank 203 to the interior of the chamber 201 again to continue to extract the salt in the high-salt fly ash. When the high-concentration salt water in the high-salt fly ash is transported to the interior of the storage tank 503, the first solenoid valve 404 is opened, and the air pump 402 is started again to drive the transport. The inlet pipe 405 draws gas from the inside of the pressurized chamber 406, so that the argon gas in the pressurized chamber 406 flows back to the inside of the gas tank 401 through the outlet pipe 403. At the same time, during the argon gas reflux process, the piston 408 is also driven to move in the direction of the limit frame 407 until the piston 408 moves to contact the outer surface of the limit frame 407, that is, the gas recovery is realized. When the salt in the high-salt fly ash in the silo 201 is completely extracted, the hydraulic rod 212 is started to shorten it, driving the baffle 213 to move to the outside of the chute 210, wherein the waterproof ring 214 acts to seal the water source in the silo 201 to prevent the material in the silo 201 from flowing out. When the baffle 213 is completely moved out of the chute 210,The high-salt fly ash in the silo 201 can move downward through the discharge port in the silo 201 to, Figure 2 In the collection basket shown.
