Waste incineration is an important method in waste recycling and treatment. The smoke produced by waste incineration contains a large amount of fly ash, which needs to be treated by fly ash treatment equipment.
[0003] However, existing fly ash treatment equipment typically uses spraying to wash away fly ash from flue gas. But due to the small contact area between the fly ash and the solution, the fly ash is not easily completely dissolved, resulting in poor treatment efficiency and hindering long-term use and widespread adoption. Therefore, those skilled in the art have provided a fly ash treatment device for waste incineration processes to address the problems mentioned in the background section. Utility Model Content

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a fly ash treatment device for waste incineration, comprising a cylinder, wherein an air inlet pipe is fixed and connected to the right end of the outer top surface of the cylinder, an exhaust hole is provided at the left end of the outer peripheral side wall of the cylinder, a hollow rotating rod is provided inside the cylinder, and a spraying component is provided on the outer wall of the hollow rotating rod.
[0006] The spraying assembly includes four hollow diverter plates fixed to the outer peripheral sidewall of the hollow rotating rod and arranged in a circular array.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0027] Please see Figure 1-5This utility model provides a technical solution for a fly ash treatment device in the process of waste incineration: it includes a cylinder 1, with support columns 4 fixedly installed at both ends of the outer periphery of the cylinder 1. Support blocks 401 are fixedly installed on the outer bottom surfaces of the two sets of support columns 4. Each support block 401 has a screw hole 402 on its outer bottom surface. Tightening the bolts in the screw holes 402 can fix the support column 4 in the working area, thereby ensuring the stability of the cylinder 1 during subsequent operation and facilitating disassembly and transportation. An air inlet pipe 101 is fixedly and continuously connected to the right end of the outer top surface of the cylinder 1, and a water inlet pipe 104 is fixedly and continuously connected to the left end of the outer top surface of the cylinder 1. Drainage pipes 105 are fixedly and continuously connected to both ends of the outer bottom surface of the cylinder 1. First, the reaction liquid is injected into the cylinder 1 along the water inlet pipe 104. Then, the air inlet pipe 101 is connected to an external conveying pipe for transporting flue gas. Subsequently, during the waste incineration process... The generated flue gas and fly ash contained in the flue gas are discharged into the cylinder 1 through the inlet pipe 101. Since the outlet of the inlet pipe 101 is perpendicular to the reaction liquid, the flue gas first comes into contact with the reaction liquid inside the cylinder 1, thereby intercepting and treating the fly ash in the flue gas. Then, the valve of the exhaust pipe 5 is opened to discharge the reaction liquid mixed with fly ash. An exhaust hole 102 is opened at the left end of the outer peripheral side wall of the cylinder 1. An exhaust pipe 5 is fixed to the left end of the outer peripheral side wall of the cylinder 1 and corresponding to the exhaust hole 102 by bolts. A filter screen 501 is fixedly installed inside the exhaust pipe 5 (the bolt connection method facilitates the later disassembly and cleaning of the filter screen 501). After the generated flue gas is pretreated with the reaction liquid inside the cylinder 1, the flue gas is discharged into the exhaust pipe 5 through the exhaust hole 102 and is intercepted and filtered again by the filter screen 501. Then, it is discharged to the outside through the exhaust pipe 5, reducing the impact of the flue gas on the external environment.
[0028] The cylinder 1 has a hollow rotating rod 103 inside, and a spraying assembly 2 is provided on the outer wall of the hollow rotating rod 103. The spraying assembly 2 includes hollow diverter plates 201 fixed to the outer peripheral side wall of the hollow rotating rod 103 and arranged in a circular array. All four hollow diverter plates 201 are interconnected with the hollow rotating rod 103. Spray nozzles 202 arranged in a linear array are connected to the outer wall of the opposite side of the four hollow diverter plates 201. One end of the hollow rotating rod 103 extends rotatably to the outer top surface of the cylinder 1 and is rotatably connected to a rotary joint 203. The outer top surface of connector 203 is fixed and connected to an infusion pipe 204. A U-shaped frame 205 is fixed to the front end of the outer top surface of the cylinder 1. A rotating shaft 206 is rotatably mounted on the inner top surface of the U-shape. A gear 207 is fixedly sleeved on the outer wall of the rotating shaft 206. A gear 208 is fixedly sleeved on the outer top surface of the cylinder 1 and on the outer peripheral side wall of the hollow rotating rod 103. A drive motor 209 is fixedly mounted on the outer top surface of the U-shaped frame 205. One end of the rotating shaft 206 extends rotatably to the outer top surface of the U-shaped frame 205 and is connected to the drive motor 209. The output end of motor 209 is fixedly connected, and gear 1 207 and gear 2 208 are meshed. First, the external pipeline used to transport the reaction liquid is connected to the infusion pipeline 204. Then, the reaction liquid is injected into the hollow rotating rod 103 along the infusion pipeline 204, then diverted into the hollow diverter plate 201, and then sprayed out through the nozzle 202. Immediately afterwards, the drive motor 209 is controlled and started to drive the rotating shaft 1 206 to drive gear 1 207 to rotate inside the U-shaped frame 205, thereby achieving the meshing of gear 1 207. Under the combined connection characteristics, the drive gear 208 drives the hollow rotating rod 103 to perform circumferential motion, thereby performing circumferential spraying of the flue gas inside the cylinder 1, thereby increasing the contact area between the reaction liquid and the fly ash in the flue gas, thus improving the treatment effect of fly ash. At the same time, during spraying, the liquid level detector installed inside the cylinder 1 (the liquid level detector is existing technology, and its working principle and structural features are not described and shown in this article) monitors the water level of the reaction liquid to prevent the accumulated reaction liquid from covering the air inlet of the water inlet pipe 104.
[0029] A rotating shaft 2 3 is rotatably installed at the center of the bottom surface of the inner cylinder 1. One end of the rotating shaft 2 3 is fixedly connected to the hollow rotating rod 103. A stirring blade 301 arranged in a linear array is symmetrically installed at the center of the outer peripheral side wall of the rotating shaft 2 3. A scraper 302 is symmetrically installed at the bottom of the outer peripheral side wall of the rotating shaft 2 3. When the hollow rotating rod 103 rotates, it synchronously drives the rotating shaft 2 3 to rotate, thereby driving the stirring blade 301 and scraper 302 to stir the reaction liquid inside the cylinder 1. This prevents the wastewater formed between fly ash and reaction liquid from remaining stagnant and stored inside the cylinder 1 for a long time, which would cause solidification and adhesion, making it difficult to discharge later. This improves practicality.
[0030] The working principle of this utility model is as follows: When in use, the flue gas generated during the waste incineration process is transported to the inside of the cylinder 1 along the air inlet pipe 101 and pretreated with the reaction liquid inside the cylinder 1.
[0031] Simultaneously, the drive motor 209 is started to drive the rotating shaft 206 to drive the gear 207 to rotate inside the U-shaped frame 205, thereby driving the gear 208 to drive the hollow rotating rod 103 to perform circumferential spraying on the flue gas inside the cylinder 1, thereby increasing the contact area between the reaction liquid and the fly ash in the flue gas and improving the treatment effect of fly ash.
[0032] Meanwhile, the flue gas that has undergone secondary treatment is discharged into the exhaust pipe 5 through the exhaust port 102 and is intercepted and filtered again by the filter screen 501. Then it is discharged to the outside through the exhaust pipe 5, thereby reducing the impact of the flue gas on the external environment.
[0033] Finally, open the drain pipe 105 to discharge the reaction liquid mixed with fly ash.
[0034] It should be noted that all electrical components mentioned in this article are electrically connected to the controller and power supply. The control method of this utility model is controlled by the controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art, so the control method and circuit connection will not be explained in detail.
[0035] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the art.
