[0023] Specifically, the filter device fixing mechanism 2 includes a mounting plate 201, a clamping seat 202, a clamping groove 203, a connecting plate 204, a clamping block 205, a fixing hole 206 and a fixing component 207. A mounting plate 201 is arranged at one end of the first air inlet 1, a connecting plate 204 is arranged on the other side of the mounting plate 201, a clamping block 205 is arranged at the side of the connecting plate 204, a fixing hole 206 is opened at the side of the clamping block 205, clamping seats 202 are arranged on both sides of the mounting plate 201, a clamping groove 203 is opened at the side of the clamping seat 202, and a fixing component 207 is arranged inside the clamping seat 202.

[0024] By adopting the above technical solutions, when fixing the air filtering mechanism 3, the clamping block 205 at the side of the connecting plate 204 is inserted into the inside of the clamping groove 203 at the side of the clamping seat 202, and then with the cooperation of the fixing component 207 and the fixing hole 206, the fixing of the air filtering mechanism 3 can be realized.

[0025] Specifically, the fixing component 207 includes a spring 2071 and a fixing rod 2074. A spring 2071 is arranged inside the clamping seat 202, and a fixing rod 2074 is arranged at one end of the spring 2071.

[0026] By adopting the above technical solution, when fixing the connection plate 204, press the fixing rod 2074. The fixing rod 2074 compresses the spring 2071 and embeds into the interior of the card seat 202. When the clamping block 205 on the side of the connection plate 204 is inserted into the interior of the card slot 203 on the side of the card seat 202, at this time the spring 2071 rebounds, thereby driving the fixing rod 2074 to insert into the interior of the fixing hole 206 to achieve the fixation of the connection plate 204, and thus fix the air filtering mechanism 3 on the side of the first air inlet 1.

[0029] In the use of this embodiment, the booster fan 18 pressurizes the air entering from the first air inlet 1 and is monitored by the main pressure gauge 17. The air passes through the drying section air duct pressure gauge 15, the combustion section air duct pressure gauge 7, and the burnout section air duct pressure gauge 6 to distribute the air intake volume inside each combustion chamber. The distributed intake air is heated by the air heater 8 in the early stage, and in the later stage when the equipment operates normally, it is heated by the first flue gas heat exchanger 14 and the second flue gas heat exchanger 10. The switching valve 9 can be used when the equipment is under maintenance and airtightness test. The second air inlet 19 can supplement the outside cold air to accelerate cooling, solving the problem that the traditional air distribution device of the waste incinerator cannot recycle the preheating of the air inside the incinerator, resulting in a large amount of resource waste when heating the air temperature in the early stage, and at the same time the traditional device cannot reasonably distribute according to the air consumption of each combustion chamber. When fixing the connection plate 204, press the fixing rod 2074. The fixing rod 2074 compresses the spring 2071 and embeds into the interior of the card seat 202. When the clamping block 205 on the side of the connection plate 204 is inserted into the interior of the card slot 203 on the side of the card seat 202, at this time the spring 2071 rebounds, thereby driving the fixing rod 2074 to insert into the interior of the fixing hole 206 to achieve the fixation of the connection plate 204, and thus fix the air filtering mechanism 3 on the side of the first air inlet 1. When it is necessary to disassemble the connection plate 204, slide the sliding block 2073 inside the sliding groove 2072. The sliding block 2073 drives the fixing rod 2074 to slide out from the interior of the fixing hole 206. At this time, the connection plate 204 can be disassembled to facilitate the cleaning of the air filtering mechanism 3.

[0031] The difference between this embodiment and Embodiment 1 is that the air filtering mechanism 3 includes a reinforcing mesh 31, an activated carbon layer 32, a non-woven fabric layer 33, and a synthetic fiber filter layer 34. The reinforcing mesh 31 is fixedly connected to the side of the connecting disc 204. The activated carbon layer 32 is arranged inside the reinforcing mesh 31. The non-woven fabric layer 33 is arranged on the side of the activated carbon layer 32. The synthetic fiber filter layer 34 is arranged on the side of the non-woven fabric layer 33.

[0032] By adopting the above technical solution, the setting of the reinforcing mesh 31 can ensure that the activated carbon layer 32, the non-woven fabric layer 33, and the synthetic fiber filter layer 34 are not easily loosened after installation. The setting of the activated carbon layer 32 can reduce the odor in the air. The setting of the non-woven fabric layer 33 can filter fine particles in the air. The setting of the synthetic fiber filter layer 34 can filter the air more efficiently, and at the same time, the efficiency and performance are more stable under long-term use.

[0033] Specifically, an imported cotton fiber layer 35 is arranged on the side of the synthetic fiber filter layer 34.

[0034] By adopting the above technical solution, the imported cotton fiber layer 35 is a completely imported filter material, which has the characteristics of small resistance, large dust capacity, light weight, stable performance, economy and environmental protection.

[0035] When this embodiment is in use, the setting of the reinforcing mesh 31 can ensure that the activated carbon layer 32, the non-woven fabric layer 33, and the synthetic fiber filter layer 34 are not easily loosened after installation. The setting of the activated carbon layer 32 can reduce the odor in the air. The setting of the non-woven fabric layer 33 can filter fine particles in the air. The setting of the synthetic fiber filter layer 34 can filter the air more efficiently, and at the same time, the efficiency and performance are more stable under long-term use. The imported cotton fiber layer 35 is a completely imported filter material, which has the characteristics of small resistance, large dust capacity, light weight, stable performance, economy and environmental protection.

[0036] The structures and operating principles of the first air inlet 1, combustion section air duct 4, burnout section air duct 5, burnout section air duct pressure gauge 6, combustion section air duct pressure gauge 7, air heater 8, switch valve 9, second flue gas heat exchanger 10, burnout section air chamber 11, combustion section air chamber 12, drying section air chamber 13, first flue gas heat exchanger 14, drying section air duct pressure gauge 15, drying section air duct 16, main pressure gauge 17, booster fan 18, and second air inlet 19 in the present utility model have been disclosed in a garbage incinerator air distribution system with Chinese patent application number 201821875076.9. Its working principle is that the booster fan 18 pressurizes the air entering from the first air inlet 1, which is monitored by the main pressure gauge 17. The air is distributed to the air intake volume inside each combustion chamber via the drying section air duct pressure gauge 15, combustion section air duct pressure gauge 7, and burnout section air duct pressure gauge 6. The distributed intake air is heated by the air heater 8 in the early stage, and in the later stage when the equipment is operating normally, it is heated by the first flue gas heat exchanger 14 and the second flue gas heat exchanger 10. The switch valve 9 can be used during equipment maintenance and airtightness testing. The second air inlet 19 can supplement external cold air to accelerate cooling, thus solving the problems that the traditional garbage incinerator air distribution device cannot recover and utilize the preheating of the air inside the incinerator, resulting in a large waste of resources when heating the air temperature in the early stage, and at the same time, the traditional device cannot reasonably distribute according to the air consumption of each combustion chamber.

[0037] Working principle and usage process of the utility model: When the utility model is in use, the booster fan 18 pressurizes the air entering from the first air inlet 1, which is monitored by the main pressure gauge 17. The air is distributed to the air intake volume inside each combustion chamber through the drying section air duct pressure gauge 15, the combustion section air duct pressure gauge 7, and the burnout section air duct pressure gauge 6. The distributed intake air is heated by the air heater 8 in the early stage of distribution. In the later stage when the equipment is operating normally, it is heated by the first flue gas heat exchanger 14 and the second flue gas heat exchanger 10. The switching valve 9 can be used when the equipment is under maintenance and airtightness testing. The second air inlet 19 can supplement the outside cold air to accelerate cooling, thus solving the problem that the air supply device of the traditional waste incinerator cannot recycle the preheating of the air inside the incinerator, resulting in a large amount of resource waste when heating the air temperature in the early stage, and at the same time, the traditional device cannot reasonably distribute according to the air consumption of each combustion chamber. When fixing the connecting plate 204, press the fixing rod 2074, and the fixing rod 2074 compresses the spring 2071 and embeds into the interior of the clamping seat 202. When the clamping block 205 on the side of the connecting plate 204 is inserted into the internal side groove 203 of the clamping seat 202, at this time, the spring 2071 rebounds, driving the fixing rod 2074 to insert into the fixing hole 206 to achieve the fixation of the connecting plate 204, thereby fixing the air filtering mechanism 3 on the side of the first air inlet 1. When it is necessary to disassemble the connecting plate 204, slide the slider 2073 inside the chute 2072, and the slider 2073 drives the fixing rod 2074 to slide out from the interior of the fixing hole 206. At this time, the connecting plate 204 can be disassembled to clean the air filtering mechanism 3. Through the setting of the reinforcement net 31, it can ensure that the activated carbon layer 32, the non-woven fabric layer 33, and the synthetic fiber filter material layer 34 are not prone to loosening after installation. The setting of the activated carbon layer 32 can reduce the peculiar smell in the air. The setting of the non-woven fabric layer 33 can filter the fine particles in the air. The setting of the synthetic fiber filter material layer 34 can filter the air more efficiently, and at the same time, under long-term use, the efficiency and performance are more stable. The imported cotton fiber layer 35 is a completely imported filter material, which has characteristics such as small resistance, large dust capacity, light weight, stable performance, economic and environmental protection, etc.
