Description

Technical Field

[0001] This utility model relates to the field of waste incineration flue gas purification and treatment technology, specifically a waste incineration flue gas purification device. Background Technology

[0002] Municipal solid waste refers to solid waste generated in daily life or in activities that provide services for daily life. Achieving harmlessness and resource recovery in the treatment of municipal solid waste, turning waste into treasure, will promote the sustainable development of the urban economy. Currently, the main methods for treating municipal solid waste domestically and internationally include incineration, composting, landfilling, and integrated harmless treatment. Among these, waste-to-energy incineration is an effective method for achieving resource recovery, reduction, and harmlessness of municipal solid waste. After incineration, waste produces exhaust gases containing a large amount of harmful components, which need to be purified by exhaust gas purification devices before being released into the atmosphere. Existing municipal solid waste incineration exhaust gas purification devices, which purify the exhaust gas by spraying purification liquid, often have a small volume of exhaust gas passing through at one time, resulting in a large amount of the sprayed purification liquid not being effectively utilized, leading to serious waste of the purification liquid, which does not conform to the concept of energy conservation and environmental protection. Utility Model Content

[0003] The purpose of this utility model is to provide a waste incineration exhaust gas purification device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a woodworking polishing and sanding mechanism, comprising a purification chamber and multiple air inlet pipes. A controller is installed on the side wall of the purification chamber. Multiple support legs are fixedly connected in a ring shape to the bottom of the purification chamber. The multiple air inlet pipes are distributed in a ring shape at equal angles. Multiple purification pipes are fixedly connected in a ring shape at equal angles to the inner bottom wall of the purification chamber. The top ends of the multiple air inlet pipes penetrate the bottom wall of the purification chamber and are respectively connected to the bottom ends of the multiple purification pipes. The top ends of the multiple air inlet pipes can discharge purified air from the purification chamber. Multiple atomizing spray nozzles are equidistantly connected along the length direction on the inner side wall of each of the multiple purification pipes. The atomizing nozzle has a first liquid delivery pipe connected to its liquid inlet end. An electromagnetic flow valve is installed on the first liquid delivery pipe and is connected to a controller. An inclined guide plate is fixedly connected between the inner walls of the purification tubes. The height of the guide plate gradually decreases from the periphery of the purification box towards the center. Multiple drain pipes are equidistantly connected to the adjacent sides of the multiple purification tubes. The bottom end of the guide plate is flush with the bottom wall of the top of the drain pipe. An airflow detection sensor is installed on the inner wall of each of the multiple purification tubes and is connected to the controller. A liquid outlet is opened at the center of the inner bottom wall of the purification box.

[0005] Preferably, the air inlet pipe is serpentine in shape. The advantage of this design is that the serpentine shape allows the waste incineration exhaust gas to pass through the air inlet pipe for a longer period of time, thereby allowing the heat of the exhaust gas to dissipate in all directions to prevent the exhaust gas temperature from becoming too high and causing the purification liquid to evaporate and be discharged into the atmosphere. This improves the environmental friendliness and practicality of the waste incineration purification equipment. At the same time, in conjunction with an external heat exchange device, the heat transferred by the exhaust gas through the wall of the air inlet pipe can be recovered and utilized, further improving the practicality and reliability of the equipment.

[0006] Preferably, the purification pipe is connected to a flow rate regulating component for adjusting the flow velocity of the exhaust gas within the purification pipe. The flow rate regulating component is connected to a controller. The advantage of this configuration is that the flow rate of the exhaust gas entering each purification pipe can be detected in real time by an airflow detection sensor. Thus, the controller can control the flow rate regulating component in real time according to the exhaust gas flow rate to adjust the flow velocity of the exhaust gas within the purification pipe. When the flow rate is low, the exhaust gas flow rate is increased; when the flow rate is high, the flow rate is decreased, allowing the purification liquid to fully contact and react with the exhaust gas. This effectively avoids excessive spraying of purification liquid and waste while fully purifying the exhaust gas, thus effectively improving the practicality and economy of the purification equipment.

[0007] Preferably, the flow rate regulating component includes multiple rotating shafts equidistantly rotatably connected to the inner wall of the purification pipe along its length. Baffles are fixedly sleeved on the outer circumferential surfaces of the multiple rotating shafts. A driving mechanism is also connected to the purification pipe. The driving mechanism is used to drive the multiple rotating shafts to rotate synchronously. The driving mechanism is connected to a controller. The advantage of this configuration is that by driving the multiple rotating shafts to rotate synchronously through the driving mechanism, the multiple rotating shafts drive the multiple baffles to rotate synchronously to adjust the angle of the baffles, thereby adjusting the gap between the two ends of the baffles and the inner wall of the purification pipe. This allows for adjustment of the effective flow area of ​​the purification pipe, thereby flexibly and reliably regulating the flow rate of the exhaust gas within the purification pipe.

[0008] Preferably, the driving mechanism includes a driving bar slidably connected to the outer wall of the purification tube via a sliding sleeve. An electric push rod is fixedly connected to the outer wall of the purification tube. The output end of the electric push rod is fixedly connected to the bottom end of the driving bar. One end of a plurality of rotating shafts passes through the side wall of the purification tube and is fixedly fitted with a driving wheel. The outer circumferential surface of the plurality of driving wheels is tightly abutted against the side of the driving bar. The advantage of this arrangement is that the electric push rod is activated to extend and retract, thereby pushing the driving bar to move back and forth. The driving bar drives the driving wheel to rotate clockwise or counterclockwise. The driving wheel drives the baffle to rotate clockwise or counterclockwise via the rotating shaft, thereby flexibly adjusting the angle of the baffle.

[0009] By adopting the above technical solution, the purification liquid can be efficiently and fully utilized.

[0010] Compared with the prior art, the beneficial effects of this utility model are: the municipal solid waste incineration exhaust gas purification equipment, Equipped with an airflow sensor and an electromagnetic flow valve, the airflow sensor can detect the flow rate of exhaust gas entering each purification pipe in real time. The controller can then adjust the electromagnetic flow valve in real time based on the exhaust gas flow rate, thereby adjusting the amount of purification liquid sprayed from the atomizing nozzles in the purification pipe accordingly. This effectively avoids excessive spraying of purification liquid and waste while fully purifying the exhaust gas, thus significantly improving the practicality and economy of the purification equipment.

An inclined guide plate 31 is attached, the height of which gradually decreases from the periphery of the purification box 1 towards the center. Multiple drain pipes 32 are equidistantly connected to the sides of multiple purification pipes 3 that are close to each other. The bottom end of the guide plate 31 is flush with the bottom wall of the top of the drain pipe 32.

[0015] refer to Figure 1 and Figure 2 The intake pipe 2 has a serpentine shape.

[0016] Specifically, the serpentine air inlet pipe 2 extends the time that the waste incineration exhaust gas spends passing through it, allowing the heat of the exhaust gas to dissipate in all directions to prevent the exhaust gas temperature from becoming too high and causing the purification liquid to evaporate and be released into the atmosphere. This improves the environmental friendliness and practicality of the waste incineration purification equipment. At the same time, in conjunction with an external heat exchange device, the heat transferred from the exhaust gas through the pipe wall of the air inlet pipe 2 can be recovered and utilized, further improving the practicality and reliability of the equipment.

Thus, the controller can control the flow rate adjustment component in real time according to the exhaust gas flow rate to adjust the flow rate of the exhaust gas in the purification pipe 3. When the flow rate is low, the exhaust gas flow rate is increased, and when the flow rate is high, the flow rate is decreased so that the purification liquid can fully contact and react with the exhaust gas. In this way, the exhaust gas can be fully purified while avoiding excessive spraying of purification liquid, thus effectively improving the practicality and economy of the purification equipment.

The drive mechanism 73 is used to drive the multiple rotating shafts 71 to rotate synchronously. The drive mechanism 73 is connected to the controller.

[0020] Specifically, the drive mechanism 73 drives multiple rotating shafts 71 to rotate synchronously, and the multiple rotating shafts 71 drive multiple baffles 72 to rotate synchronously to adjust the angle of the baffles 72, thereby adjusting the gap between the two ends of the baffles 72 and the inner wall of the purification pipe 3. In this way, the effective flow area of ​​the purification pipe 3 can be adjusted, thereby flexibly and reliably adjusting the flow speed of the exhaust gas in the purification pipe 3.

[0021] refer to Figures 3-6 The drive mechanism 73 includes a drive bar 732 slidably connected to the outer wall of the purification tube 3 via a sliding sleeve 731. An electric push rod 733 is fixedly connected to the outer wall of the purification tube 3. The output end of the electric push rod 733 is fixedly connected to the bottom end of the drive bar 732.
