[0023] The working principle of this utility model is:

[0024] When in use, turn on the fan 7. Under the suction of the fan 7, the dust-laden gas in the paint workshop will enter the filter bag dust collector 3 through the dust hood 2 and the dust suction pipe 1. The filter bag 302 in the filter bag dust collector 3 intercepts the dust in the dust-laden gas, and the intercepted dust falls into the bottom of the shell 301, and then enters the dust collecting cylinder 8 which is sealed and connected to the bottom of the filter bag dust collector 3 from the bottom of the shell 301. Then the gas enters the spray tank 601 through the connecting pipe 5. The circulating water pump 603 is turned on to extract the water in the spray tank 601 and transport it to the spray tank 601 through the water pipe 602 and spray it from the top. The water comes into contact with the dust in the gas to reduce the dust. Finally, the gas is discharged to the outside through the fan 7. When the equipment stops running, the personnel can hold the snap-on handle 9 and pull it upwards. Both ends of the snap-on handle 9 The first clamp head 902 and the second clamp head 903 will rotate and fall off from the card slot of the card plate 10. At this time, the dust collecting barrel 8 will drop and contact the ground. Then the personnel can pull the dust collecting barrel 8 out from the bottom of the filter bag dust collector 3, thereby cleaning the dust in the dust collecting barrel 8. When installing the dust collector, the card-connecting handle 9 is lifted upward to keep the first clamp head 902 and the second clamp head 903 horizontal, and then the dust collecting barrel 8 is slowly pushed into the bottom of the filter bag dust collector 3 from the opposite side of the card slot of the card plate 10. When the first clamp head 902 and the second clamp head 903 enter the card slot of the card plate 10, the card-connecting handle 9 is pulled downward again, and the first clamp head 902 and the second clamp head 903 will be clamped on the card plate 10, and the dust collecting barrel 8 will also be suspended in the air and sealed with the filter bag dust collector 3.
