[0026] Beneficial effects:

[0027] 1. Significantly improve resource utilization and realize the resource-based transformation of fly ash.

[0028] This invention utilizes a fly ash collection and treatment assembly to collect fly ash carried in incinerator exhaust gas. Further dechlorination treatment via water washing separates and recovers valuable components (such as salts like NaCl and KCl). These salts can be used as de-icing agents or industrial salts, while the dechlorinated fly ash can be processed into lightweight aggregates, ceramsite, or roadbed materials through high-temperature or ambient-temperature mineralization processes. Compared to traditional methods of directly disposing of fly ash as waste, this invention significantly improves resource utilization and achieves the resource-based transformation of waste.

[0029] 2. Improve exhaust gas filtration efficiency and optimize fly ash collection structure.

[0030] This invention features a capture net inside the separator tube, along with a discharge motor, pull ropes, and a guide frame, enabling efficient interception and centralized collection of fly ash. By pulling and releasing two ropes, the capture net flips over, utilizing the inertial and tension forces generated to peel off the firmly attached fly ash layer from the inner wall and shake it into the funnel below. Compared to simple left-right movement or vibration, this method provides more thorough and efficient ash removal, while reducing the area occupied inside the separator tube and improving the flow efficiency of exhaust gas and the amount of fly ash captured.

[0031] 3. High water washing efficiency and thorough dechlorination of fly ash.

[0032] The fly ash washing process in this invention utilizes the rotation of the filter cylinder to cause intermittent contact between the main and auxiliary inclined blocks. Combined with the sliding of the shower base on the fixed tank and the action of the shaking spring, the shower base generates high-frequency vibration, continuously dispersing the accumulated fly ash. Simultaneously, the washing liquid is sprayed upwards through the shower base, achieving comprehensive and uniform washing of the fly ash. This design significantly improves the contact efficiency between fly ash and washing liquid, ensuring thorough dechlorination and increasing the conversion rate of usable products.

[0033] 4. Prevent filter clogging and improve the stability of the exhaust system.

[0034] This invention incorporates a gas filtration and anti-clogging component inside the exhaust stack. A fan wheel rotates under wind power, driving the main cross shaft, double-headed grooved rod, and secondary cross shaft. This drives the lifting plate to intermittently contact the contact blocks on the lower side of the movable ring. Combined with the action of a vibrating spring, multiple contact blocks intermittently strike the surface of the filter screen. This structure effectively prevents the filter screen from being clogged by fly ash, ensuring smooth exhaust gas discharge and improving the long-term operational stability of the system.

[0035] 5. Facilitates maintenance and replacement, improving equipment operability.

[0036] This invention incorporates a double-headed grooved rod, a movable nest, and a telescopic spring into the installation structure of the activated carbon filter plate. By compressing the spring, the movable nest disengages from the main and secondary cross shafts, allowing for easy disassembly or replacement of the activated carbon filter plate. During normal operation, the spring is in a compressed, energy-storing state, ensuring a tight fit between the movable nest and the cross shaft, guaranteeing reliable power transmission. This design greatly facilitates the maintenance and replacement of the filter media without hindering transmission performance, reducing operational difficulty and maintenance costs.

[0038] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0039] The present invention discloses an incinerator exhaust gas treatment and reuse device and an incinerator, which are mainly applied to scenarios where existing incinerator exhaust gas treatment devices directly treat fly ash carried in the exhaust gas as waste, and the valuable components contained therein cannot be converted into usable products, resulting in a significant reduction in resource utilization.

[0040] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 10A device for treating and reusing incinerator exhaust gas includes a fixed frame 3. A separation pipe 6 is fixedly connected to the upper side of the fixed frame 3. A fly ash collection and treatment assembly 7 is arranged on the lower side of the fixed frame 3. The fly ash collection and treatment assembly 7 includes a door-mounted washing cylinder 716. A buffer cylinder 717 is fixedly connected to the inner wall of the lower end of the door-mounted washing cylinder 716. The upper side of the buffer cylinder 717 and the inner wall of the upper end of the door-mounted washing cylinder 716 are connected to the same filter cylinder 718 through a bearing. A through hole is opened on the upper side of the buffer cylinder 717, and a fixed groove cylinder 724 is inserted into the through hole. The fixed groove cylinder 724 is located at... Inside the filtrate cylinder 718, a shower base 722 is slidably connected to the outer wall of the fixed groove cylinder 724. A shaking spring 723 is sleeved on the outer wall of the fixed groove cylinder 724. One end of the shaking spring 723 is fixedly connected to the buffer cylinder 717, and the other end of the shaking spring 723 is fixedly connected to the shower base 722. Multiple secondary inclined blocks 721 are fixedly connected at equal intervals on the upper side of the shower base 722. Multiple main inclined blocks 720 are fixedly connected at equal intervals on the inner wall of the filtrate cylinder 718. The inclined surfaces of the multiple main inclined blocks 720 are in contact with the inclined surfaces of the corresponding secondary inclined blocks 721.

[0041] In this invention, a driven gear 719 is fixedly connected to the upper outer wall of the filter cylinder 718, and a brake hole is opened on the upper side of the door-mounted washing cylinder 716. A brake shaft 714 is connected to the inside of the brake hole through a bearing. A brake gear 713 is fixedly connected to the outer wall of the end of the brake shaft 714 located inside the door-mounted washing cylinder 716. The brake gear 713 meshes with the driven gear 719. A brake motor 715 is fixedly connected to the upper side of the door-mounted washing cylinder 716. The drive end of the brake motor 715 is connected to the end of the brake shaft 714 located outside the door-mounted washing cylinder 716 through a coupling.

[0042] In this invention, a connecting plate 14 is fixedly connected to the upper outer wall of the washing drum 716 with a door. A fixing hole is opened on one side of the connecting plate 14, and a vacuum tube 16 is fixedly connected inside the fixing hole. One end of the vacuum tube 16 is inserted into the inside of the washing drum 716 with a door. A vacuum pump 15 is fixedly connected to one side of the connecting plate 14. The suction end of the vacuum pump 15 is connected to the other end of the vacuum tube 16. A drain hole is opened on the lower outer wall of the washing drum 716 with a door, and one end of the drain pipe 9 is inserted into the drain hole.

[0043] In this invention, a collection trough is provided at the contact position between the separation tube 6 and the fixing frame 3. A funnel 703 is fixedly connected inside the collection trough on the fixing frame 3. A collection hole is provided on the lower side of the funnel 703. One end of the conveying tube 705 is fixedly connected inside the collection hole. The other end of the conveying tube 705 is inserted into the inside of the door washing drum 716. A solenoid valve 704 is provided on the outer wall of the conveying tube 705. A fixing ring 707 is fixedly connected inside the separation tube 6.

[0044] In this invention, a capture net 706 is sewn to one side of the fixing ring 707, and two guide frames 712 are fixedly connected at equal intervals inside the separation tube 6. The two guide frames 712 are located on both sides of the capture net 706. Fixed arc plates 702 are fixedly connected at equal intervals on the outer wall of the separation tube 6, and two take-up and release frames 710 are fixedly connected at equal intervals on the upper side of the two fixed arc plates 702.

[0045] In this invention, two take-up and release racks 710 located on the same fixed arc plate 702 have rotating holes on opposite sides. The two rotating holes are connected to the same rotating shaft 711 via bearings. Take-up and release wheels 701 are fixedly connected to the outer walls of the two rotating shafts 711. One end of a pull rope 708 is wound around the outer wall of each of the two pull ropes 701. The other ends of the two pull ropes 708 pass through the separation tube 6 and the corresponding guide frame 712, respectively, and are fixedly connected to the inner and outer walls of the capture net 706. A take-up and release motor 709 is fixedly connected to one side of each of the two take-up and release racks 710. The drive ends of the two take-up and release motors 709 are connected to one end of the corresponding rotating shaft 711 via couplings.

[0046] Specifically, during operation, the exhaust gas generated inside the incinerator body 1, along with the fly ash it carries, enters the separation pipe 6 through the furnace tube 2. Part of the exhaust gas is discharged through the exhaust pipe 4 inside the separation pipe 6. However, due to the action of the filter screen 809, only the exhaust pipe 4 receives the exhaust gas, while the fly ash intercepted by the filter screen 809 is swept towards one end of the separation pipe 6 by another portion of the exhaust gas. During this process, due to the interception by the capture net 706, the fly ash is collected inside the capture net 706, and the exhaust gas that has had the fly ash filtered out can pass through the return pipe 5. Inside the exhaust stack 4, after the exhaust gas is completely discharged, the two collectors 709 are activated, causing the two rotating shafts 711 to drive the corresponding collection and release wheels 701 to rotate in different directions. This achieves the pulling and releasing of the two pull ropes 708. Under this action, the inside of the capture net 706 flips outward, allowing the fly ash captured inside the capture net 706 to fall into the funnel 703 through the collection trough. It should be noted that the "inside flipping outward" is not simply pulling the capture net 706 to move left and right inside the separation tube 6. Specifically, the two collectors 709 drive the corresponding collection and release wheels 701 to rotate in opposite directions, tightening one pull rope 708 while simultaneously releasing the other. This action forces the open end of the capture net 706 to remain stationary, while its closed end flips due to the force of the pull ropes 708, ultimately exposing the entire inner surface of the capture net 706 to the outside.This process is similar to turning over a bag or gloves. Its purpose is to use the inertial force and tension generated by the turning motion to peel off the fly ash accumulation layer firmly attached to the inner wall of the mesh bag and shake it off into the funnel 703 below. Compared to simple left-right movement or vibration, this method has a more thorough and efficient ash removal effect. Before the fly ash falls into the funnel 703, the vacuum pump 15 and vacuum tube 16 create a vacuum inside the door-mounted washing cylinder 716. Therefore, after the fly ash falls into the funnel 703, the solenoid valve 704 is opened, and under the action of negative pressure adsorption, all the fly ash enters the filter cylinder 718 and finally accumulates in the shower base 722. Then, while closing the solenoid valve 704, the brake motor 715 is activated, driving the brake shaft 714 to rotate. Because the brake gear 713 on the brake shaft 714 meshes with the driven gear 719, the filter cylinder 718 rotates. Simultaneously, multiple main inclined blocks 720 fixed inside the filter cylinder intermittently contact and press against multiple secondary inclined blocks 721 on the shower base 722. The shower base 722 slides on the fixed groove cylinder 724, and under the action of the shaking spring 723, it intermittently vibrates at high frequency, continuously shaking away the fly ash. Regarding the sliding of the shower base 722... The dynamic setting, specifically the structure, is as follows: The fixed groove cylinder 724 acts as a hollow fixed guide column, vertically fixed to the buffer cylinder 717. The shower base 722 has a through hole at its center that matches the outer diameter of the fixed groove cylinder 724. Through this through hole, the shower base 722 can slide up and down onto the outer wall of the fixed groove cylinder 724. To ensure smooth sliding, a lubricating layer or sliding bearing can be provided on the inner wall of the through hole. The shaking spring 723 is sleeved on the outer periphery of the fixed groove cylinder 724, with its lower end abutting against the upper surface of the buffer cylinder 717 and its upper end abutting against the lower surface of the shower base 722, providing a continuous upward restoring elastic force for the shower base 722. When the filtrate... When the cylinder 718 rotates, the main inclined block 720 periodically presses down on the secondary inclined block 721, forcing the shower base 722 to overcome the elastic force of the shaking spring 723 and slide downward along the fixed groove cylinder 724. When the main inclined block 720 and the secondary inclined block 721 are misaligned, the elastic force of the shaking spring 723 pushes the shower base 722 upward along the fixed groove cylinder 724 to quickly reset, thereby generating high-frequency vibration. At the same time, the washing liquid inside the washing liquid cylinder 12 is pumped into the buffer cylinder 717 through the infusion pipe 10 by the water pump 11, and then sprayed out through the fixed groove cylinder 724 and finally through the shower base 722, thereby washing and dechlorinating the fly ash. The washing liquid containing NaCl / KCl salt is separated and discharged through the outlet pipe 9. It can be recycled as a snow melting agent or industrial salt. The dechlorinated fly ash can be collected and subsequently processed into lightweight aggregate, ceramsite or roadbed material through high temperature or normal temperature mineralization processes.

[0047] In specific application scenarios, the pulling and releasing of the two pull ropes 708 reduces the area occupied inside the separation tube 6 while facilitating the tension and outward turning of the capture net 706, improving the efficiency of exhaust gas flow and increasing the amount of fly ash captured. At the same time, the two guide frames 712 ensure that the tension of the two pull ropes 708 remains at the same level during use, ensuring the stability of the capture net 706. The fly ash is shaken apart by the intermittent high-frequency vibration of the shower base 722, and combined with the washing liquid rinsing from bottom to top, the fly ash can be thoroughly washed, greatly improving the washing efficiency and the conversion rate of usable products.

[0052] Specifically, when the exhaust gas enters the exhaust stack 4, the activated carbon filter plate 804 performs preliminary filtration of the toxic substances contained in the exhaust gas, reducing the content of toxic substances in the exhaust gas. At the same time, the fan wheel 802 rotates under the action of wind force. As the fan wheel 802 rotates continuously, the main cross shaft 803 indirectly drives the secondary cross shaft 805 to rotate through the double-headed grooved rod 814, so that the lifting plate 811 intermittently contacts the inclined surfaces of multiple contact inclined blocks 812. Combined with the action of the movable ring 808 and the shaking spring 807, the multiple contact inclined blocks 812 intermittently knock on the surface of the ash filter screen 809, thereby preventing the ash filter screen 809 from being blocked by fly ash and improving the flow and emission efficiency of the exhaust gas.

[0053] In specific application scenarios, the two movable nests 810 can be brought closer together by overcoming the action of their corresponding telescopic springs 813, thereby disengaging the two movable nests 810 from their corresponding main cross shafts 803 and secondary cross shafts 805. This allows for the disassembly and replacement of the activated carbon filter plate 804, ensuring filtration efficiency. Under normal installation conditions, the two telescopic springs 813 are in a compressed, energy-storing state. In this state, the telescopic springs 813 generate an outward thrust, tightly pressing the two movable nests 810 into the engagement structure of the main cross shaft 803 and secondary cross shaft 805, ensuring that power can be stably and reliably transmitted from the fan wheel 802 to the lifting plate 811, achieving an anti-clogging knocking function. When it is necessary to disassemble or replace the activated carbon filter plate 804, the operator needs to... To overcome the compression force of the two telescopic springs 813, the two movable nests 810 are pinched together (i.e., brought closer to each other) by hand, so that the ends of the movable nests 810 are removed from the main cross shaft 803 and the secondary cross shaft 805 respectively. At this point, the lock can be released, and the double-headed grooved rod 814 along with the activated carbon filter plate 804 can be removed from the transmission system. After removal, the telescopic springs 813 can be restored from the compressed state to the free extension state. When reinstalling, the springs are compressed again and nested back onto the cross shaft, using their elastic force to automatically lock. This design ensures the separability of the transmission connection and the reliability of the connection. At the same time, since the main cross shaft 803 and the secondary cross shaft 805 are connected to the corresponding movable nests 810 by a movable insertion method, the transmission effect is not affected without hindering disassembly.

[0054] Working principle: During operation, the exhaust gas generated inside the incinerator body 1, along with the fly ash it carries, enters the separation pipe 6 through the furnace drum 2. Part of the exhaust gas is discharged through the exhaust pipe 4 inside the separation pipe 6. Due to the action of the filter screen 809, only the exhaust pipe 4 receives the exhaust gas. The fly ash intercepted by the filter screen 809 is swept towards one end of the separation pipe 6 by another portion of the exhaust gas. During this process, due to the interception by the capture net 706, the fly ash is collected inside the capture net 706. The exhaust gas that has had the fly ash filtered out can enter through the return pipe 5. Inside the exhaust stack 4, after the exhaust gas is completely discharged, the two collectors 709 are turned on, causing the two rotating shafts 711 to drive the corresponding collector wheels 701 to rotate in different directions, thus realizing the pull and release of the two pull ropes 708. Under this action, the inside of the capture net 706 is turned outward, allowing the fly ash captured inside the capture net 706 to fall into the funnel 703 through the collection trough. Before the fly ash falls into the funnel 703, the vacuum pump 15 and vacuum tube 16 keep the inside of the door-mounted water washing cylinder 716 under vacuum. In an empty state, after the fly ash falls into the funnel 703, the solenoid valve 704 is opened. Under the action of negative pressure adsorption, all the fly ash enters the filter cylinder 718 and eventually accumulates on the shower base 722. Then, the solenoid valve 704 is closed and the brake motor 715 is turned on to drive the brake shaft 714 to rotate. Since the brake gear 713 on the brake shaft 714 meshes with the driven gear 719, the filter cylinder 718 rotates. While the filter cylinder 718 is rotating, the multiple main inclined blocks 720 fixed inside it intermittently interact with the shower head. Multiple sub-sloping blocks 721 on the shower base 722 come into contact and are squeezed. The shower base 722 slides on the fixed groove cylinder 724 and, in conjunction with the action of the shaking spring 723, causes the shower base 722 to vibrate intermittently at high frequency, thereby continuously shaking off the fly ash on it. At the same time, the washing liquid inside the washing liquid cylinder 12 is pumped by the water pump 11 into the buffer cylinder 717 through the infusion pipe 10. Then, it passes through the fixed groove cylinder 724 and is finally sprayed out through the shower base 722, thereby washing and dechlorinating the fly ash. The washing liquid containing NaCl / KCl salt is separated and discharged through the outlet pipe 9. It can be recycled as a snow melting agent or industrial salt. The dechlorinated fly ash can be collected and subsequently processed by high-temperature or room-temperature mineralization processes to produce lightweight aggregate, ceramsite, or roadbed materials.

[0055] When the exhaust gas enters the exhaust stack 4, the activated carbon filter plate 804 performs preliminary filtration of the toxic substances contained in the exhaust gas, reducing the content of toxic substances in the exhaust gas. At the same time, the fan wheel 802 rotates under the action of wind power. As the fan wheel 802 rotates continuously, the main cross shaft 803 indirectly drives the secondary cross shaft 805 to rotate through the double-headed grooved rod 814, so that the lifting plate 811 intermittently contacts the inclined surfaces of multiple contact inclined blocks 812. Combined with the action of the movable ring 808 and the shaking spring 807, the multiple contact inclined blocks 812 intermittently knock on the surface of the filter screen 809, thereby preventing the filter screen 809 from being blocked by fly ash. The two movable nests 810 can be brought closer together by overcoming the action of the corresponding telescopic springs 813, so that the two movable nests 810 are disengaged from the corresponding main cross shaft 803 and secondary cross shaft 805, thereby realizing the disassembly and replacement of the activated carbon filter plate 804.
