A number of cloth bags 108 are installed on the installation plate 107 through the holes. The mechanism 200 includes a second outer shell 201. The waste gas enters from the air inlet 105. When the waste gas passes through the cloth bag 108, the surface fiber structure of the cloth bag 108 will prevent the particulate matter from passing through, thereby intercepting the particulate matter on the surface of the cloth bag 108. The waste gas continues to move upward. A ventilation pipe 203 is provided on one side of the second outer shell 201. The ventilation pipe 203 connects the first outer shell 101 and the second outer shell 201. The waste gas enters the second outer shell 201 through the ventilation pipe 203. An electromagnetic heating pipe 204 is provided inside the second outer shell 201. The electromagnetic heating pipe 204 conducts electricity to form a high-temperature environment inside the entire second outer shell 201. The waste gas is oxidized at high temperature when flowing into the second outer shell 201, so that the harmful substances in the waste gas are oxidized and filtered into harmless substances. An air outlet 202 is provided above the electromagnetic heating pipe 204. The waste gas is discharged from the air outlet 202 after being filtered.

An electromagnetic pulse generator 103 is provided on the backing plate 102. A number of air blowing ports 110 are provided on the electromagnetic pulse generator 103. A framework 109 is provided inside the cloth bag 108.

[0024] The waste gas enters from the air inlet 105. When the waste gas passes through the cloth bag 108, the surface fiber structure of the cloth bag 108 will prevent the particulate matter from passing through, thereby intercepting the particulate matter on the surface of the cloth bag 108. The waste gas continues to move upward. The waste gas enters the second outer shell 201 through the ventilation pipe 203. An electromagnetic heating pipe 204 is provided inside the second outer shell 201. The electromagnetic heating pipe 204 conducts electricity to form a high-temperature environment inside the entire second outer shell 201. The waste gas is oxidized at high temperature when flowing into the second outer shell 201, so that the harmful substances in the waste gas are oxidized and filtered into harmless substances. An air outlet 202 is provided above the electromagnetic heating pipe 204. The waste gas is discharged from the air outlet 202 after being filtered. The particulate matter is intercepted on the surface of the cloth bag by the surface fiber structure of the cloth bag. The electromagnetic heating pipe is conducted to form a high-temperature environment inside the entire second outer shell, so that the waste gas is oxidized at high temperature when flowing into the second outer shell, and the harmful substances in the waste gas are oxidized and filtered into harmless substances.

[0025] As Figure 1 and Figure 2As shown, a sealing ring is provided at the connection between the first outer shell 101 and the electromagnetic pulse device 103, and an ash discharge valve 106 is provided at the bottom end of the blanking port 104.

[0027] The present utility model provides an energy-saving industrial waste gas filtering device, and the specific working principle is as follows: The waste gas enters from the air inlet 105. When the waste gas passes through the dust bag 108, the surface fiber structure of the dust bag 108 will prevent particulate matter from passing through, thereby intercepting the particulate matter on the surface of the dust bag 108. The waste gas continues to move upward. The lower end of the second outer shell 201 is provided with an air vent pipe 203, and the air vent pipe 203 connects the first outer shell 101 and the second outer shell 201. The waste gas enters the second outer shell 201 through the air vent pipe 203. An electromagnetic heating tube 204 is provided inside the second outer shell 201. The electromagnetic heating tube 204 conducts electricity to form a high-temperature environment inside the entire second outer shell 201.
