Description

Technical Field

[0001] The present invention relates to the technical field of high-salt fly ash, and in particular to a device and method for treating high-salt fly ash leachate. Background Art

[0002] With the acceleration of urbanization and the continuous increase in the amount of garbage generated, garbage incineration has become more and more widely used as an efficient garbage disposal method. In the process of garbage incineration, fly ash is produced as an inevitable product. 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 poses great harm to the environment and human health. It has become a difficult problem that needs to be overcome urgently in the current environmental protection field.

[0010] Furthermore, the outer wall of the rotating shaft is fixedly connected with a plurality of scrapers, and the plurality of scrapers are in contact with the inner wall of the distillation barrel. The outer wall of the rotating shaft is fixedly connected with a plurality of fixing rods, and the side of the plurality of fixing rods away from the rotating shaft is fixedly connected with a plurality of spiral blades.

[0011] Furthermore, the top of the fixed plate is fixedly connected to a slide rod 1, the top of the slide rod 1 passes through the adsorption plate, the outer wall of the slide rod 1 is slidably connected to a slide plate, the outer wall of the slide rod 1 is provided with a spring 1, the top of the spring 1 is fixedly connected to the slide plate, and the bottom of the spring 1 is fixedly connected to the fixed plate.

[0012] Furthermore, the top of the slide rod 1 is fixedly connected with a semicircular block 1, the outer wall of the slide rod 1 is slidably connected with a semicircular block 2, the semicircular block 2 is in contact with the semicircular block 1, and two slide grooves 1 are provided on the adsorption plate.

[0013] Furthermore, the inner walls of the two slide grooves are slidably connected to slide rods 2, and the outer walls of the two slide rods 2 are sleeved with springs 2. The sides of the two springs 2 that are away from each other are fixedly connected to slide groove 1, and the sides of the slide rods 2 close to slide rod 1 are fixedly connected to the limiting block, and the sides of the springs 2 that are close to each other are fixedly connected to the limiting block.

[0014] Furthermore, a handle is fixedly connected to the top of the sliding rod three, a limit plate is fixedly connected to the inner wall of the sliding groove two, and a limit groove is provided on the sliding rod three, and the limit groove is adapted to the limit plate.

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

[0016] 1. The present invention sets a heating and stirring mechanism. After the adsorption plate and the filter barrel are installed, the high-salt fly ash leachate can be poured from the filter barrel into the distillation barrel. When pouring, the discharge port of the distillation barrel needs to be closed. At this time, the high-salt fly ash leachate will pass through the filter barrel to filter the larger substances in it, and then pass through the adsorption plate again. At this time, the adsorption plate will adsorb the harmful substances in the high-salt fly ash leachate, and then the high-salt fly ash leachate will reach the bottom of the distillation barrel, and then the heating wire and the motor will be started. At this time, the heating wire will heat the bottom of the distillation barrel. As the motor rotates, the rotating shaft will also rotate, and then the fixed rod on the rotating shaft will also carry the spiral blades with it. Rotate, and the scraper will also rotate with the rotating shaft. The scraper will clean the inner wall of the distillation barrel. The high-salt fly ash leachate in the distillation barrel will be evenly heated by the rotation of the spiral blades. After the high-salt fly ash leachate is evenly heated, steam will be generated. At this time, the steam will pass through the distillation tube to the condensing device, and thus some harmful substances in the high-salt fly ash leachate will be removed by distillation, so that liquid boiling, splashing and other phenomena caused by local overheating can be avoided, making the distillation process more stable and safer, while also improving the distillation efficiency, making volatile substances such as water more fully vaporized, and improving the separation effect.

[0017] 2. The present invention sets a quick loading and unloading mechanism to place the adsorption plate in the distillation barrel. At this time, the adsorption plate is lowered horizontally. As the adsorption plate is lowered, it will first come into contact with the semicircular block 1, and then the limit block on the adsorption plate will also come into contact with the semicircular block 1. Then, the adsorption plate is pressed downward. At this time, the limit blocks will be squeezed away from each other, and then the slide bar 2 will also slide in the slide groove 1. At this time, the spring 2 will be squeezed by the limit block and contract. As the limit block contracts, it will pass through the semicircular block 1. At this time, the adsorption plate is installed. If the adsorption plate needs to be removed after a long time, press the adsorption plate downward with force. At this time, the semicircular block 2 will be pressed downward by the limit block, and then the semicircular block 2 will come into contact with the slide plate. The rear slide plate will also slide downward. As the slide plate slides downward, the pressure of spring one will increase, and then the limit block will pass through semicircular block two. After the limit 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 carry semicircular block two, the slide plate and the limit block to move upward at the same time. As the semicircular block two continues to rise, it will contact semicircular block one, and then the continued rise will make the limit block pass through semicircular block one and semicircular block two, thereby achieving the disassembly of the adsorption plate, so that the adsorption plate can be replaced, so that there is no need for complicated tools and tedious operating steps, and the installation of the adsorption plate can be completed quickly, thereby improving the efficiency of equipment assembly and facilitating the rapid commissioning of the entire high-salt fly ash leachate treatment system.

[0018] 3. The present invention sets a hinge mechanism, and the lid of the distillation barrel can be covered after the adsorption plate is installed, and then the filter barrel is placed at the feed port on the distillation barrel, and then the hole on the filter barrel is aligned with the hole on the limit plate, and then the slide rod three is inserted into the hole. As the slide rod three is inserted, the limit plate will be stretched open, and by continuously pressing the handle downward, the limit plate will be completely fitted with the limit groove, and the filter barrel will be fixed. When there are too many impurities in the filter barrel, the handle can be rotated, and the slide rod three will rotate as the handle rotates, and then the slide rod three will stretch the limit plate open, and then the slide rod three can be pulled out, so that the filter barrel can be removed, thereby cleaning the impurities in the filter barrel, so that there will be no shaking, displacement, etc. during the filtration process of high-salt fly ash leachate, thereby ensuring the smooth progress of the filtration process and avoiding leachate leakage or poor filtration effect caused by instability of the filter barrel.

With the continuous rise, the semicircular block 2 (316) will come into contact with the semicircular block 1 (315), and then the continuous rise will make the limit block (3110) pass through the semicircular block 1 (315) and the semicircular block 2 (316), thereby achieving the disassembly of the adsorption plate (101), so that the adsorption plate (101) can be replaced; S3: After the adsorption plate (101) is installed, the lid of the distillation barrel (1) can be covered, and then the filter barrel (102) can be placed at the inlet of the distillation barrel (1). Then, the hole on the filter barrel (102) and the hole on the limit plate (414) are aligned, and then the slide bar (412) is inserted into the hole. As the slide bar (412) is inserted, the limit plate (414) will be stretched open. Continuously press the handle (413) downward, and the limit plate (414) will align with the limit groove ( 415) is completely fitted, and the filter barrel (102) is fixed at this time. When there are too many impurities in the filter barrel (102), the handle (413) can be rotated. When the handle (413) is rotated, the slide bar three (412) will also rotate accordingly, and then the slide bar three (412) will open the limit plate (414), and then the slide bar three (412) can be pulled out, so that the filter barrel (102) can be removed, and the impurities in the filter barrel (102) can be cleaned.
