Description

Technical Field

[0001] This utility model relates to the field of waste incineration boiler exhaust gas treatment technology, specifically a particulate dust separation device for waste incineration boiler exhaust gas. Background Technology

[0002] The primary thermal treatment method for municipal solid waste is incineration. The flue gas from incineration contains a large amount of particulate matter with uneven particle size distribution (including inhalable particulate matter PM10, fine particulate matter PM2.5, and fly ash). Direct emission of these particles would cause serious air pollution. Particulate matter separation devices are one of the core units of the waste incineration flue gas purification system. Their function is to efficiently capture and separate dust particles from the flue gas through physical or electromechanical coupling, ensuring that flue gas emissions meet national environmental standards.

[0003] Existing patent document CN217662236U discloses a particulate matter separation device for waste incineration boiler flue gas. The technical solution includes a boiler body and an absorption water tank. The top of the boiler body is the flue gas outlet. An inlet pipe is welded to the top left end of the absorption water tank, and an outlet pipe is welded to the bottom right end. It also includes a separation mechanism comprising a processing component, a circulation component, and a sewage discharge component. The absorption water tank is located on the right side of the boiler body. The processing component and the circulation component are both fixedly installed on the absorption water tank. The beneficial effects of this invention are: the absorption water in the absorption tank effectively adsorbs particulate matter in the flue gas, achieving separation of flue gas and particulate matter; the absorption water can directly cool the flue gas, eliminating the need for subsequent separate cooling; and it facilitates replacement of the absorption water by staff. The operation is simple and convenient, improving flue gas treatment efficiency and making it suitable for widespread use.

[0004] However, while existing particulate matter separation devices for waste incineration boiler flue gas can separate dust particles from the flue gas, the dust particles are collected by the filter bags during the separation process. Cleaning the dust particles on the filter bags requires workers to disassemble and clean them, which not only requires regular cleaning but also increases the difficulty of cleaning. Therefore, we propose a particulate matter separation device for waste incineration boiler flue gas. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a particulate dust separation device for waste incineration boiler flue gas, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a particulate matter separation device for waste incineration boiler flue gas, comprising,

[0007] The collection mechanism includes a device body, a dust collection box slidably connected to the front of the device body, a sliding groove above the dust collection box on the front of the device body, a fixed frame slidably connected to the inner side of the sliding groove, and a collection cover and a connecting pipe welded to the inside of the device body.

[0008] The separation mechanism includes a sealing plate mounted on the front of the main body of the device, a mounting plate welded to the back of the sealing plate, a separation cylinder bolted to the bottom of the mounting plate, a mounting bracket welded inside the separation cylinder, a cleaning motor mounted inside the mounting bracket, a cleaning shaft fixed to the drive end of the cleaning motor via a coupling, a retractable rod welded to the outside of the cleaning shaft, an adjusting rod slidably connected to one end of the retractable rod, an adjusting spring mounted inside the retractable rod, and an inlet opening at the top of the mounting plate.

[0009] Preferably, support legs are welded to the four corners of the bottom of the main body of the device, and an air inlet pipe is bolted to the top of the main body of the device.

[0010] Preferably, a negative pressure fan is bolted to one side of the main body of the device, an exhaust pipe is bolted to the top of the negative pressure fan, and an exhaust pipe is threaded to one side of the negative pressure fan, with the exhaust pipe bolted to the main body of the device.

[0011] Preferably, the dust collection box has a handle embedded in its front and a dust collection port on its top.

[0012] Preferably, the inner wall of the separation cylinder is fitted with multiple layers of filter bags, the diameter of which is adapted to the inner diameter of the separation cylinder.

[0013] Preferably, a cleaning brush is bolted to one end of the adjusting rod, and the cleaning brush is in close contact with the multi-layer filter bag.

[0014] This utility model provides a particulate dust separation device for waste incineration boiler flue gas, which has the following beneficial effects:

[0015] This type of particulate matter separation device for waste incineration boiler flue gas, through a dust collection box, works by having a negative pressure fan activated. The fan generates negative pressure, which enters the main body of the device through the extraction pipe and acts on the inlet pipe. The inlet pipe draws in the waste incineration boiler flue gas, which then passes through a collection hood and enters the separation cylinder via the inlet. Multiple layers of filter bags filter the flue gas, trapping dust particles. The gas then passes through the filter bags and the separation cylinder before being discharged through the extraction pipe and the negative pressure fan, exiting from the exhaust pipe. When a large amount of dust adheres to the multi-layer filter bags, the operator starts the cleaning motor, which drives the cleaning shaft to rotate. At this time, the cleaning shaft drives the cleaning brush to clean the dust on the multi-layer filter bags through the extension rod and adjustment rod. The dust can then enter the dust collection box through the connecting pipe and be collected. During cleaning, the adjustment spring pushes the adjustment rod, which pushes the cleaning brush to fit against the inner wall of the multi-layer filter bags. When the dust collection box has collected a certain amount and needs to be cleaned, the operator can simply pull the dust collection box out of the main body of the device to pour out the dust particles. This allows the particulate dust separation device to be cleaned without disassembling the filter components, thus simplifying the cleaning process. Attached Figure Description

[0023] The collection mechanism 1 includes a device body 101, a dust collection box 107 is slidably connected to the front of the device body 101, a sliding groove 110 is provided on the front of the device body 101 above the dust collection box 107, a fixing frame 111 is slidably connected to the inner side of the sliding groove 110, and a collection cover 112 and a connecting pipe 113 are welded to the inside of the device body 101.

[0024] The separation mechanism 2 includes a sealing plate 201 mounted on the front of the main body 101 of the device. A mounting plate 202 is welded to the back of the sealing plate 201. A separation cylinder 203 is bolted to the bottom of the mounting plate 202. A mounting bracket 205 is welded inside the separation cylinder 203. A cleaning motor 206 is installed inside the mounting bracket 205. A cleaning shaft 207 is fixed to the drive end of the cleaning motor 206 via a coupling. A take-up and release rod 208 is welded to the outside of the cleaning shaft 207. An adjusting rod 209 is slidably connected to one end of the take-up and release rod 208. An adjusting spring 210 is installed inside the take-up and release rod 208. An inlet 212 is opened at the top of the mounting plate 202.

[0025] Furthermore, support legs 102 are welded to the four corners of the bottom of the main body 101, and an air inlet pipe 103 is bolted to the top of the main body 101. The support legs 102 make the device more stable.

[0026] Furthermore, a negative pressure fan 104 is bolted to one side of the main body 101 of the device, and an exhaust pipe 106 is bolted to the top of the negative pressure fan 104. An exhaust pipe 105 is threaded to one side of the negative pressure fan 104 and bolted to the main body 101 of the device. When the negative pressure fan 104 is started, the negative pressure fan 104 operates to generate negative pressure. The negative pressure enters the main body 101 of the device through the exhaust pipe 105 and acts on the air inlet pipe 103. At this time, the air inlet pipe 103 draws the exhaust gas from the waste incineration boiler.

[0027] Furthermore, a handle 108 is embedded in the front of the dust collection box 107, and a dust collection port 109 is opened on the top of the dust collection box 107, through which dust particles are easily collected by the dust collection box 107.

[0028] Furthermore, the inner wall of the separator 203 is equipped with multiple layers of filter bags 204, the diameter of which is adapted to the inner diameter of the separator 203. The dust particles can be separated from the exhaust gas through the multiple layers of filter bags 204.

[0030] Working Principle: After installation, first check the installation, fixation, and safety precautions of this utility model. When using the particulate matter separation device in the waste incineration boiler exhaust gas, the operator starts the negative pressure fan 104. The negative pressure fan 104 generates negative pressure, which enters the main body 101 of the device through the extraction pipe 105 and acts on the inlet pipe 103. At this time, the inlet pipe 103 draws in the waste incineration boiler exhaust gas. The waste incineration boiler exhaust gas enters the separation cylinder 203 through the central hood 112 and inlet 212. At this time, the multi-layer filter bags 204 filter the boiler exhaust gas, and the dust particles in the exhaust gas are intercepted by the multi-layer filter bags 204. The gas can then be discharged through the multi-layer filter bags 204 and the separation cylinder 203, and discharged from the exhaust pipe 106 through the extraction pipe 105 along the negative pressure fan 104. When a large amount of dust adheres to the multi-layer filter bag 204, the operator starts the cleaning motor 206, which drives the cleaning shaft 207 to rotate. At this time, the cleaning shaft 207 drives the cleaning brush 211 to clean the dust on the multi-layer filter bag 204 through the retracting rod 208 and the adjusting rod 209. The dust can then enter the dust collection box 107 through the connecting pipe 113 for collection. During cleaning, the adjusting spring 210 pushes the adjusting rod 209, which pushes the cleaning brush 211 to adhere to the inner wall of the multi-layer filter bag 204. When the dust collection box 107 has collected a certain amount and needs to be cleaned, the operator pulls the dust collection box 107 removal device body 101 through the handle 108 to pour out the dust particles. This completes the use of this utility model. This utility model has a simple structure and is safe and convenient to use.
