TECHNICAL FIELD
[0001] The present application relates to the technical field of high-salt fly ash treatment, in particular to a high-salt fly ash resource treatment device. BACKGROUND
[0002] High-salt fly ash refers to fly ash generated during the combustion of materials containing high salt content. Fly ash is a fine particle generated during the combustion process and is usually discharged into the atmosphere with flue gas. High-salt fly ash is named because it contains a high concentration of salt substances such as sodium chloride and sodium sulfate. A high-salt fly ash resource treatment device is a device specifically designed to treat and utilize high-salt fly ash. This device aims to reduce the potential negative impact of high-salt fly ash on the environment and to turn waste into treasure by extracting reusable resources.
[0003] Currently, during the incineration of municipal waste, a large amount of salt-containing substances such as table salt in kitchen waste and some chlorine-containing plastics are present in household waste. When these wastes are incinerated, chlorine elements will exist in various forms in fly ash, and then condense on the surface of fly ash particles as the flue gas cools down, including sodium chloride. To achieve the recycling of resources in high-salt fly ash, workers often extract salt from high-salt fly ash by water washing and evaporation. In the process of treating high-salt fly ash, to ensure that the salt in the fly ash is fully extracted and to further improve the extraction rate of salt, multiple washings are often used, as it is difficult to completely extract the salt in the fly ash with one washing.

[0033] In this embodiment, when the water containing salt completely enters the inside of the pressurizing chamber 406, the fifth electromagnetic valve 216 is closed, the air pump 402 is started, and the output pipe 403 draws the argon gas in the inside of the gas tank 401, the gas enters the inside of the pressurizing chamber 406 through the input pipe 405, and under the action of the strong pressure, the piston 408 is pushed to move forward along the inner wall of the pressurizing chamber 406, wherein, as shown in FIG. 4, the piston 408 is provided with a plurality of holes 409, and the holes 409 are arranged in a staggered manner. Figure 7As shown, the limiting frame 407 limits the movement of the piston 408 to prevent 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 saltwater in the pressurized chamber 406 forward, and under the action of pressure, the moisture in the saltwater passes through the semi-permeable membrane body 410. The pore size of the semi-permeable membrane body 410 is small enough to allow only water molecules to pass through, but not ions such as Na+ and Cl-. The surface of the semi-permeable membrane body 410 has different hydrophilicity, which affects its interaction with water molecules. Hydrophilic materials can more easily absorb and conduct water molecules. When the semi-permeable membrane body 410 separates the saltwater and pure water, due to the existence of concentration difference, water molecules will migrate through the semi-permeable membrane body 410 from the side with low salt concentration to the side with high salt concentration. This process is called osmosis. Osmosis is a natural selection that allows the system to reach equilibrium. Since the salt in the saltwater cannot pass through the semi-permeable membrane body 410, the salt in the water can only remain on the other side of the semi-permeable membrane body 410. At the same time, the second electromagnetic valve 412 is opened, allowing the pressurized chamber 406 to communicate with the return pipe 411, and then the water source that has passed through the semi-permeable membrane body 410 without salt enters the water tank 203 through the return pipe 411, thereby achieving water source recovery and water salt purification. When the water source that has passed through the semi-permeable membrane body 410 is basically completely delivered to the inside of the water tank 203, the second electromagnetic valve 412 is closed. In addition, when the piston 408 moves to the side close to the mounting frame 409 under the action of gas pressure, the gas tank 401 is in a state of negative pressure due to the continuous output of gas. When the salt purification in the pressurized chamber 406 is completed, the gas pump 402 is closed, and then the first electromagnetic valve 404 is closed, and the third electromagnetic valve 502 is opened. At this time, due to the high pressure in the pressurized chamber 406 and the negative pressure in the gas tank 401, the pressure sensor 413 is also opened to detect the pressure in the gas tank 401. When the pressure in the gas tank 401 is insufficient, the gas 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. The pressure sensor 413 utilizes the characteristic that the resistance of the material changes with the change of pressure. When pressure is applied, it will cause a slight deformation, thereby causing a change in resistance. By measuring the change in resistance, the pressure applied to the sensor can be calculated. When the gas tank 401 is connected to the pressurized chamber 406 through the delivery pipe 501, the high-concentration saltwater in the pressurized chamber 406 can enter the interior of the gas tank 401 under the action of pressure difference. When the high-concentration saltwater is delivered to the interior of the gas tank 401, the third electromagnetic valve 502 is closed, and the one-way valve 505 is opened. The one-way valve 505 is a valve that allows fluid to flow in only one direction and prevents reverse flow. Its working principle is mainly based on the pressure difference of the fluid. In the static or flow direction does not meet the case, the valve is usually in the closed state, preventing fluid flow. At this time, the valve depends on the action of gravity,The valve is sealed on the valve seat, when the fluid pressure is applied to the valve disc from the inlet of the valve, if the pressure is greater than the pressure above the valve disc, the valve disc will overcome the counterforce of gravity to 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, sealing on the valve seat, thereby preventing the fluid from flowing in the opposite direction, so that the high-concentration brine in the gas tank 401 enters the inside of the storage tank 503 through the pipeline 504, and then the fourth electromagnetic valve 205 can be opened again to transport the water source in the water tank 203 to the inside of the warehouse body 201 again, continue to extract the salt in the high-salt fly ash, through the circulation utilization, save the water source, solve the problem of wasting resources in the process of extracting the salt in the high-salt fly ash in the prior art.

[0038] The method of using and working principle of the device: in the process of high-salt fly ash resource treatment, first, the quantitative high-salt fly ash is put into the surface of the spiral blade 208 through the feeding bin 202 along the leakage hole barrel 209, then the positive and negative motor 206 is started, the spiral shaft 207 is rotated, and then the spiral blade 208 is rotated, so that the material in the feeding bin 202 is conveyed and stirred along the bin body 201 by 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 inside of the bin body 201 through the conveying pipe 204, then contacts with the fly ash along the leakage hole barrel 209, so that the fly ash is stirred and mixed with water under the driving of the spiral blade 208, so as to realize the separation between salt and high-salt fly ash, when the material is conveyed to the side close to the positive and negative motor 206, the positive and negative motor 206 is started again, the spiral blade 208 is reversed, and then the material is conveyed and stirred along the bin body 201 in the reverse direction, when the high-salt fly ash is mixed, the fifth electromagnetic valve 216 is opened, so that the water source containing salt in the material is output along the small hole in the leakage hole barrel 209, and flows out to the inside of the pressurizing bin 406 through the connecting pipe 215, wherein the aperture of the leakage hole barrel 209 can only penetrate the water source, the high-salt fly ash cannot penetrate from the leakage hole barrel 209, the high-salt fly ash is mixed, stirred and conveyed by the stirring assembly 2, when the water containing salt completely enters the inside of the pressurizing bin 406, the fifth electromagnetic valve 216 is closed, the air pump 402 is started, the output pipe 403 extracts argon from the inside of the gas tank 401, the gas enters the inside of the pressurizing bin 406 through the input pipe 405, and the piston 408 is pushed forward along the inner wall of the pressurizing bin 406 under the action of strong pressure, wherein, as Figure 7As shown, the limiting bracket 407 limits the piston 408, preventing it from moving to a position where it contacts the inner wall of the pressurization chamber 406. The movement of the piston 408 pushes the brine in the pressurization chamber 406 forward. Under pressure, the water in the brine passes through the semi-permeable membrane body 410. Since the salt in the brine cannot pass through the semi-permeable membrane body 410, the salt in the water can only remain on the other side of the semi-permeable membrane body 410. At the same time, the second solenoid valve 412 is opened, thereby connecting the pressurization chamber 406 with the return pipe 411. This allows the salt-free water that has passed through the semi-permeable membrane body 410 to re-enter the water tank 203 through the return pipe 411. When the water that has passed through the semi-permeable membrane body 410 is basically completely transported... After reaching the water tank 203, the second solenoid valve 412 is closed. Additionally, when the piston 408 moves to the side near the mounting bracket 409 under air pressure, the gas tank 401 is under negative pressure due to continuous gas output. After salt purification in the pressurization chamber 406 is complete, the air pump 402 is turned off, and the first solenoid valve 404 is closed. Then, the third solenoid valve 502 is opened. At this time, the pressurization chamber 406 is under high pressure, while the gas tank 401 is under negative pressure. Simultaneously, the pressure sensor 413 is activated to detect the pressure inside the gas tank 401. If the pressure inside the gas tank 401 is insufficient, the air pump 402 is restarted to extract gas from the gas tank 401 until the pressure inside the gas tank 401 reaches the required value. When the lead pipe... When the gas tank 401 is connected to the pressurization chamber 406, the high-concentration brine in the pressurization chamber 406 can enter the gas tank 401 through the inlet pipe 501 under the action of pressure difference. After the high-concentration brine has been delivered to the gas tank 401, the third solenoid valve 502 is closed and the one-way valve 505 is opened, so that the high-concentration brine in the gas tank 401 enters the storage tank 503 through the pipe 504 for storage. Then, the fourth solenoid valve 205 can be opened again to deliver the water source in the water tank 203 to the chamber 201 to continue extracting salt from the high-salt fly ash. After the high-concentration brine in the high-salt fly ash is delivered to the storage tank 503, the first solenoid valve 404 is opened and the air pump 402 is started again to drive the conveyor. Gas is drawn from the pressurization chamber 406 by the inlet pipe 405, causing the argon gas in the pressurization chamber 406 to flow back into the gas tank 401 through the outlet pipe 403. Simultaneously, during the argon gas recirculation, the piston 408 moves towards the limit frame 407 until it contacts the outer surface of the limit frame 407, thus achieving gas recovery. Once the salt in the high-salt fly ash in the chamber 201 has been completely extracted, the hydraulic rod 212 is activated, shortening it and moving the baffle 213 outwards from the chute 210. The waterproof ring 214 seals the water source in the chamber 201, preventing material from flowing out. Once the baffle 213 is completely removed from the chute 210...The high-salt fly ash in the bin body 201 can be moved downward to the collection basket shown in the drawing through the discharge port in the bin body 201.
