Description

Technical Field

[0001] This invention relates to the field of high-salt fly ash technology, specifically to a device and method for treating high-salt fly ash leachate. Background Technology

[0002] With the acceleration of urbanization and the continuous increase in waste generation, waste incineration, as an efficient waste treatment method, is being used more and more widely. During the waste incineration process, fly ash is inevitably generated. When fly ash is landfilled, temporarily stored, or subsequently treated, it will generate high-salt fly ash leachate due to factors such as precipitation and groundwater infiltration. This leachate has a complex composition and is extremely harmful to the environment and human health, which has become a problem that urgently needs to be solved in the field of environmental protection.

[0003] However, existing high-salt fly ash leachate treatment devices are not convenient for uniform heating of the high-salt fly ash leachate during use. If the heat distribution is uneven, most of the liquid will not be able to obtain enough heat in time, and volatile substances such as water will not be able to fully vaporize. The distillation efficiency is extremely low, and a large amount of substances that should be separated remain in the liquid, resulting in poor separation effect and difficulty in meeting the strict requirements for the purification treatment of high-salt fly ash leachate. Summary of the Invention

[0004] The purpose of this invention is to provide a device and method for treating high-salt fly ash leachate. By setting up a heating and stirring mechanism, the invention solves the problems of inconvenience in uniformly heating high-salt fly ash leachate, local overheating that prevents most of the liquid from receiving sufficient heat in time, difficulty in fully vaporizing volatile substances such as water, extremely low distillation efficiency, and a large amount of substances that should be separated remaining in the liquid, resulting in poor separation effect and difficulty in meeting the strict requirements for the purification treatment of high-salt fly ash leachate.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0006] The present invention is a device and method for treating high-salt fly ash leachate, comprising a distillation tank, wherein the distillation tank is provided with a heating and stirring mechanism, several quick loading and unloading mechanisms and several hinge mechanisms.

[0007] An adsorption plate is installed inside the distillation barrel, and a filter barrel is slidably connected to the top of the distillation barrel. A distillation tube is connected to the distillation barrel. The heating and stirring mechanism includes a conical plate fixedly connected to the outer wall of the distillation barrel. The quick loading and unloading mechanism includes a fixed plate fixedly connected to the inner wall of the distillation barrel. The hinge mechanism includes a second sliding groove opened on the distillation barrel. A third sliding rod is slidably connected in the second sliding groove. The third sliding rod extends to the outside of the distillation barrel and passes through the filter barrel.

[0008] Furthermore, a heating wire is fixedly connected to the inner wall of the conical plate, a motor frame is fixedly connected to the bottom of the conical plate, and a motor is fixedly connected to the inner wall of the motor frame.

[0009] Furthermore, the output shaft of the motor is fixedly connected to a rotating shaft via a coupling, a guide plate is rotatably connected to the outer wall of the rotating shaft, and an auger is fixedly connected to the outer wall of the rotating shaft, with the auger in contact with the inner wall of the distillation tank.

[0010] Furthermore, a number of scrapers are fixedly connected to the outer wall of the rotating shaft, and the scrapers are in contact with the inner wall of the distillation tank. A number of fixing rods are fixedly connected to the outer wall of the rotating shaft, and a number of spiral blades are fixedly connected to the side of the fixing rods away from the rotating shaft.

[0011] Furthermore, a sliding rod is fixedly connected to the top of the fixed plate, the top of the sliding rod penetrates the adsorption plate, a sliding plate is slidably connected to the outer wall of the sliding rod, a spring is sleeved on the outer wall of the sliding rod, the top of the spring is fixedly connected to the sliding plate, and the bottom of the spring is fixedly connected to the fixed plate.

[0012] Furthermore, a semicircular block is fixedly connected to the top of the slide rod, and a semicircular block is slidably connected to the outer wall of the slide rod. The semicircular block is in contact with the semicircular block, and two grooves are formed on the adsorption plate.

[0013] Furthermore, each of the two inner walls of the slide groove is slidably connected to a slide rod, and each of the two slide rods is fitted with a spring. The sides of the two springs that are far apart from each other are fixedly connected to the slide groove. A limit block is fixedly connected to the side of the slide rod that is close to the slide rod, and the sides of the springs that are close to each other are fixedly connected to the limit block.

[0014] Furthermore, a handle is fixedly connected to the top of the slide rod three, a limiting plate is fixedly connected to the inner wall of the slide groove two, and a limiting groove is opened on the slide rod three, the limiting groove being adapted to the limiting plate.

[0015] The present invention has the following beneficial effects:

[0016] 1. This invention, through the installation of a heating and stirring mechanism, allows high-salt fly ash leachate to be poured from the filter tank into the distillation tank after the adsorption plate and filter tank are installed. The outlet of the distillation tank must be closed during pouring. The high-salt fly ash leachate will then pass through the filter tank to filter out larger substances, and subsequently pass through the adsorption plate again. The adsorption plate will adsorb harmful substances in the high-salt fly ash leachate. The leachate will then reach the bottom of the distillation tank. The heating wire and motor are then activated. The heating wire heats the bottom of the distillation tank, and as the motor rotates, the rotating shaft also rotates, causing the fixed rod on the shaft to move along with the spiral blades. As the shaft rotates, the scraper also rotates, cleaning the inner wall of the distillation tank. The rotation of the spiral blades ensures the high-salt fly ash leachate inside the tank is evenly heated, generating steam. This steam then travels through the distillation tube to the condenser, where distillation removes some harmful substances from the leachate. This process avoids localized overheating that could lead to boiling over and splashing, making the distillation process more stable and safe. It also improves distillation efficiency, allowing for more complete vaporization of volatile substances like water, thus enhancing the separation effect.

[0017] 2. This invention, through the setting of a quick loading and unloading mechanism, places the adsorption plate inside the distillation tank. The adsorption plate is then laid horizontally down. As it is laid down, the adsorption plate first contacts the first semicircular block, and then the limiting block on the adsorption plate also contacts the first semicircular block. Then, the adsorption plate is pressed down, causing the limiting blocks to be squeezed away from each other. Subsequently, the second sliding rod slides within the first sliding groove. At this time, the second spring is compressed by the limiting blocks and contracts. As the limiting blocks contract, they pass through the first semicircular block, thus achieving the effect of installing the adsorption plate. If the adsorption plate needs to be disassembled after a long period, the adsorption plate is pressed down forcefully. The second semicircular block is then pressed down by the limiting blocks, and subsequently, the second semicircular block contacts the sliding plate. The rear slide plate will also slide downwards. As the slide plate slides downwards, the pressure of spring one will increase. Then the limiting block will pass through semicircular block two. After the limiting block passes through semicircular block two, the adsorption plate can be released. At this time, the pressure on spring one will pop out, and then it will move upwards along with semicircular block two, the slide plate and the limiting block. As it continues to rise, semicircular block two will contact semicircular block one. Then, the continuous rise will push the limiting block through semicircular block one and semicircular block two, thereby achieving the disassembly of the adsorption plate, so that the adsorption plate can be replaced. This allows the adsorption plate to be installed quickly without complicated tools and cumbersome operation steps, improving the efficiency of equipment assembly and facilitating the rapid commissioning of the entire high-salt fly ash leachate treatment system.

[0018] 3. This invention, through the installation of a hinge mechanism, allows the distillation tank lid to be closed after the adsorption plate is installed. The filter tank is then placed at the feed inlet of the distillation tank, and the holes on the filter tank and the limiting plate are aligned. The sliding rod three is then inserted into the hole. As the sliding rod three is inserted, the limiting plate is opened. Continuing to press the handle downwards, the limiting plate will completely fit into the limiting groove, thus securing the filter tank. If there are too many impurities in the filter tank, the handle can be rotated. As the handle rotates, the sliding rod three will also rotate, opening the limiting plate. The sliding rod three can then be pulled out, allowing the filter tank to be removed. This process cleans the impurities from the filter tank, preventing shaking or displacement during the filtration of high-salt fly ash leachate, ensuring smooth filtration, and avoiding problems such as leachate leakage or poor filtration effect caused by filter tank instability.

[0019] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

A guide plate 216 is rotatably connected to the outer wall of the shaft 215, and an auger 217 is fixedly connected to the outer wall of the shaft 215. The auger 217 is in contact with the inner wall of the distillation tank 1.

Several fixed rods 219 are fixedly connected to the outer wall of the shaft 215, and several spiral blades 2110 are fixedly connected to the side of the fixed rods 219 away from the shaft 215. By setting up a heating and stirring mechanism 2, phenomena such as liquid boiling and splashing caused by local overheating can be avoided, making the distillation process more stable and safe. At the same time, it can also improve the distillation efficiency, make volatile substances such as water more fully vaporized, and improve the separation effect.

[0033] The quick loading and unloading mechanism 3 includes a fixed plate 311 fixedly connected to the inner wall of the distillation tank 1. A sliding rod 312 is fixedly connected to the top of the fixed plate 311. The top of the sliding rod 312 passes through the adsorption plate 101. A sliding plate 313 is slidably connected to the outer wall of the sliding rod 312. A spring 314 is sleeved on the outer wall of the sliding rod 312. The top of the spring 314 is fixedly connected to the sliding plate 313, and the bottom of the spring 314 is fixedly connected to the fixed plate 311. A semi-circular block 315 is fixedly connected to the top of the sliding rod 312. A second semi-circular block 316 is slidably connected to the outer wall of the sliding rod 312. The second semi-circular block 316 contacts the first semi-circular block 315. Two sliding grooves 317 are provided, and sliding rods 318 are slidably connected to the inner walls of both sliding grooves 317. Springs 319 are fitted onto the outer walls of both sliding rods 318. The sides of the two springs 319 that are far apart from each other are fixedly connected to the sliding grooves 317. A limiting block 3110 is fixedly connected to the side of the sliding rod 318 that is closer to the sliding rod 312, and the sides of the springs 319 that are close to each other are fixedly connected to the limiting block 3110. By setting up a quick loading and unloading mechanism 3, the installation of the adsorption plate can be completed quickly without complicated tools and cumbersome operating procedures, which improves the efficiency of equipment assembly and facilitates the rapid commissioning of the entire high-salt fly ash leachate treatment system.

[0034] The hinge mechanism 4 includes a second slide groove 411 on the distillation tank 1, a third slide rod 412 slidably connected in the second slide groove 411, the third slide rod 412 extending to the outside of the distillation tank 1 and passing through the filter tank 102, a handle 413 fixedly connected to the top of the third slide rod 412, a limiting plate 414 fixedly connected to the inner wall of the second slide groove 411, and a limiting groove 415 opened on the third slide rod 412, the limiting groove 415 being adapted to the limiting plate 414. By setting the hinge mechanism 4, the high-salt fly ash leachate will not shake or shift during the filtration process, ensuring the smooth progress of the filtration process and avoiding problems such as leachate leakage or poor filtration effect caused by the instability of the filter tank.

[0035] In use, first place the adsorption plate 101 in the distillation tank 1, then lower the adsorption plate 101 horizontally. As it is lowered, the adsorption plate 101 will first contact the semicircular block 315, and then the limiting block 3110 on the adsorption plate 101 will also contact the semicircular block 315. Then, press the adsorption plate 101 down, at which point the limiting block 3110 will be squeezed away from each other, and then the sliding rod 318 will slide in the sliding groove 317. At this time, the spring 319 will be compressed by the limiting block 3110 and contract. As the limiting block 3110 contracts, it will pass through the semicircular block 315, thus achieving the effect of installing the adsorption plate 101. If the adsorption plate 101 needs to be disassembled after a long time, press down firmly. When the adsorption plate 101 is activated, the second semicircular block 316 will be pressed downwards by the limiting block 3110. The second semicircular block 316 will then contact the sliding plate 313, which will slide downwards. As the sliding plate 313 slides downwards, the pressure on the first spring 314 will increase. The limiting block 3110 will then pass through the second semicircular block 316. After the limiting block 3110 passes through the second semicircular block 316, the adsorption plate 101 can be released. The pressure on the first spring 314 will then cause it to pop out, carrying the second semicircular block 316, the sliding plate 313, and the limiting block 3110 upwards simultaneously. As it continues to rise, the second semicircular block 316 will contact the first semicircular block 315. The continued upward movement will then cause the limiting block 3110 to pass through the second semicircular block 316. By installing block 315 and semicircular block 316, the adsorption plate 101 can be disassembled and replaced. After installing the adsorption plate 101, the lid of the distillation tank 1 can be closed. Then, the filter tank 102 is placed at the feed inlet of the distillation tank 1. Next, the hole on the filter tank 102 is aligned with the hole on the limiting plate 414. Then, the sliding rod 412 is inserted into the hole. As the sliding rod 412 is inserted, the limiting plate 414 will be opened. By continuously pressing down the handle 413, the limiting plate 414 will be completely fitted with the limiting groove 415, thus achieving the effect of fixing the filter tank 102. When there are too many impurities in the filter tank 102, the handle 413 can be rotated. When the handle 413 is rotated, the sliding rod 412 will be inserted. The slide bar 412 will then open the limiting plate 414, allowing the slide bar 412 to be pulled out and the filter barrel 102 to be removed. This allows for the cleaning of impurities inside the filter barrel 102. After the adsorption plate 101 and filter barrel 102 are installed, the high-salt fly ash leachate can be poured from the filter barrel 102 into the distillation tank 1. The outlet of the distillation tank 1 must be closed during pouring. The high-salt fly ash leachate will pass through the filter barrel 102 to filter out larger substances, and then pass through the adsorption plate 101 again. The adsorption plate 101 will adsorb harmful substances in the high-salt fly ash leachate. The high-salt fly ash leachate will then reach the bottom of the distillation tank 1. Then, the heating wire 212 and motor 214 are activated.At this time, the heating wire 212 heats the bottom of the distillation tank 1. As the motor 214 rotates, the rotating shaft 215 also rotates. Subsequently, the fixed rod 219 on the rotating shaft 215 rotates along with the spiral blades 2110. The scraper 218 also rotates with the rotating shaft 215, cleaning the inner wall of the distillation tank 1. The rotation of the spiral blades 2110 ensures that the high-salt fly ash leachate in the distillation tank 1 is evenly heated. After being evenly heated, steam is generated. This steam then passes through the distillation tube 103 to the condenser, thus achieving distillation to remove some of the harmful substances from the high-salt fly ash leachate.
