Metal membrane sheets 5 arranged at equal intervals are fixedly connected to the bottom and upper surfaces of the two connecting plates 4. A fixing plate 6 is fixedly connected to the front of the two connecting plates 4. An air inlet 7 is provided on the left side of the shell 1. The dust removal mechanism 2 includes two support plates 201. A compressed air storage tank 202 is fixedly connected to the upper surfaces of the two support plates 201. A connecting pipe 203 is fixedly connected to the bottom surface of the compressed air storage tank 202. A pulse is installed on the outer surface of the connecting pipe 203. The output end of the connecting pipe 203 is fixedly connected to the connecting shell 205. The bottom surface of the connecting shell 205 is fixedly connected to the equally spaced blow pipes 206. The output end of each blow pipe 206 is fixedly connected to the upper surface of the shell 1. The shell 1 provides a stable installation foundation for the whole. The connecting plate 4 firmly supports the metal diaphragm 5, which achieves high-temperature and high-efficiency filtration. In the dust removal mechanism 2, the support plate 201 fixes the compressed air storage tank 202, which completes pulse dust removal through the connecting pipe 203, pulse valve 204, connecting shell 205 and blow pipes 206 to avoid diaphragm blockage. The air outlet monitoring and flow guiding mechanism 3 ensures stable exhaust. The fixing plate 6 facilitates component installation, and the air inlet 7 guides the airflow in.

[0017] The air outlet monitoring and guiding mechanism 3 includes a guide hood 303. The outer surface of the guide hood 303 is fixedly connected to the right side of the housing 1. A temperature sensor 301 and a dust concentration sensor 302 are fixedly installed on the inner wall of the housing 1. Filter screens 304 are fixedly connected to both the inner wall of the guide hood 303 and the inner wall of the air inlet 7. A mounting plate 305 is fixedly connected to the inner wall of the guide hood 303. In the air outlet monitoring and guiding mechanism 3, the temperature sensor 301 can monitor the temperature inside the housing 1 in real time to avoid high temperature damage to components; the dust concentration sensor 302 can accurately determine the dust concentration to ensure filtration effect; the guide hood 303 optimizes the exhaust flow direction and improves emission stability; the filter screens 304 on the inner wall of the air inlet 7 and the guide hood 303 respectively achieve primary filtration of the intake air and prevention of dust backflow.

[0018] A flow sensor 306 is fixedly installed on the left side of the mounting plate 305, and a guide fan 307 is fixedly installed on the right side of the mounting plate 305. A dust hopper 8 is fixedly connected to the bottom of the housing 1, and a dust discharge pipe 9 is fixedly connected to the bottom of the dust hopper 8. A dust discharge valve 10 is installed on the outer surface of the dust discharge pipe 9. A touch control screen 12 is fixedly installed on the front of the fixing plate 6. An observation window 11 is opened on the front of the fixing plate 6, and a high-temperature resistant transparent plate is fixedly connected to the inner wall of the observation window 11. Two fixing blocks 13 are fixedly connected to both the left and right sides of the housing 1, and support legs 14 are fixedly connected to the bottom of both sets of fixing blocks 13. The flow sensor 306 on the mounting plate 305 monitors the airflow in real time, and the guide fan 307 assists in adjusting the airflow speed and direction to ensure smooth exhaust. The dust hopper 8 collects dust in a concentrated manner, and the dust discharge pipe 9, in conjunction with the dust discharge valve 10, enables convenient dust discharge and avoids accumulation and blockage. The touch control screen 12 on the fixing plate 6 facilitates operation and adjustment of equipment parameters.

[0019] The working principle of this utility model is as follows: First, dust-laden gas enters the housing 1 through the air inlet 7. The filter screen 304 on the inner wall of the air inlet 7 performs preliminary filtration of large particulate impurities in the gas. Then, the gas flows to the metal diaphragm 5, which is fixedly supported by the connecting plate 4. The metal diaphragm 5 performs fine filtration of dust, achieving gas-dust separation. Then, the temperature sensor 301 and the dust concentration sensor 302 on the inner wall of the housing 1 monitor the internal temperature and dust concentration in real time, respectively. The data can be fed back to the touch control screen 12 on the fixed plate 6. At the same time, the flow sensor 306 on the mounting plate 305 on the inner wall of the guide hood 303 monitors the airflow. The guide fan 307 assists in the process. The airflow direction is optimized so that the purified gas is discharged smoothly from the guide hood 303. The staff can also observe the internal working conditions through the observation window 11. Finally, when dust accumulates on the surface of the metal diaphragm 5 and affects filtration, the dust removal mechanism 2 is activated. The compressed air tank 202 supported by the support plate 201 releases compressed air, which enters the connecting shell 205 through the connecting pipe 203 and the pulse valve 204. Then, the metal diaphragm 5 is pulse-jet cleaned through the blow pipe 206. The falling dust falls into the dust hopper 8. After accumulating to a certain amount, the dust discharge valve 10 is opened, and the dust is discharged through the dust discharge pipe 9. The support leg 14 connected to the fixed block 13 always ensures the overall stable operation of the equipment.
