[0029] In the utility model, in using, waste gas first inputs into waste gas pipe 8 through gas feeding equipment, then waste gas will enter into air inlet chamber 7, then waste gas will enter into filter cylinder 11 through the duct, and filter cylinder 11 will filter out particulate matter in waste gas, and then realize the effect of waste gas filtration, and the filtered waste gas will enter into first regenerator 1 from air inlet pipe 4 in processing cavity 6, then waste gas will enter into combustion chamber 2 and second regenerator 3 in turn and be discharged, and the treatment of waste gas and the recycling of waste heat are completed.

[0031] Please refer to Figure 1 , 34, wherein: a steel pipe 13 is inserted through the housing 5 and slidably connected thereto; a metal plate 14 is fitted on the steel pipe 13 and fixedly connected thereto; an air pump 15 is installed on the top of the metal plate 14; the air pump 15's suction pipe is set upwards; the air pump 15's outlet pipe is connected to the steel pipe 13; a lifting ring 16 is connected to the bottom end of the steel pipe 13; the lifting ring 16 is arranged in a ring shape and fitted on the filter cylinder 11; an air outlet groove 17 is opened on the inner side of the lifting ring 16; the air outlet groove 17 is arranged in a ring shape; a second spring 18 is fitted on the steel pipe 13; the two ends of the second spring 18 are fixedly connected to the metal plate 14 and the housing 5 respectively.

[0032] In this invention, after cleaning the filter cartridge 11, the user turns on the air pump 15. The air pump 15 inputs air into the steel pipe 13, and the air enters the lifting ring 16 from the steel pipe 13. Then, the air is sprayed out from the air outlet 17. During the process, the user presses the metal plate 14, and the lifting ring 16 descends along the surface of the filter cartridge 11. During this process, the air is sprayed out from the air outlet 17 and passes through the filter cartridge 11 in the opposite direction, thereby achieving the effect of backflushing and cleaning the filter cartridge 11. This effectively improves the cleaning effect of the filter cartridge 11 and can also adhere and discharge the scraped particulate waste, thereby improving the practicality of the device.
