When it is necessary to clean the ash removal and filtration bin body 402 and the hollow columnar filter element 413, the externally connected purging gas source enters the inside of the hollow columnar filter element 413 under the action of positive pressure. The externally connected purging gas source purges the accumulated ash in the hollow columnar filter element 413 to the outside, and together with the accumulated ash inside the ash removal and filtration bin body 402, enters the ash and slag conveying pipe 408 from the ash and slag discharge port 407 at the bottom of the ash removal and filtration bin body 402, and is discharged from the ash removal and filtration bin body 402 under the action of the externally connected compressed air purging gas source to achieve the effect of continuous automatic slag discharge.

Then, the sample enters the dust removal and filtration bin main body 402 from the "L"-shaped wear-resistant sampling pipe 405 through the heat tracing cable 404 and the sample air inlet 403. The dusty industrial flue gas is divided into two streams inside the dust removal and filtration bin main body 402. One stream of the dusty industrial flue gas is discharged from the ash discharge port 407 at the bottom of the dust removal and filtration bin main body 402 under the negative pressure of the compressed air purging gas source connected to the ash conveying pipe 408, and the air flow direction is the same as that of the compressed air purging gas source connected to the ash conveying pipe 408. The other stream of the dusty industrial flue gas is deashed by flowing through the hollow cylindrical filter element 413 under the suction of the external CEMS sampling pump. The dust-free sample gas is discharged from the sample output interface 409 and is transported to the external CEMS cabinet along the externally connected cable to play the role of dust removal and sample preparation. When it is necessary to clean the dust removal and filtration bin main body 402 and the hollow cylindrical filter element 413, the externally connected purging gas source enters the inside of the hollow cylindrical filter element 413 from the purging input interface 410 under the action of positive pressure. The externally connected purging gas source blows the accumulated ash in the hollow cylindrical filter element 413 to the outside, and together with the accumulated ash inside the dust removal and filtration bin main body 402, it enters the ash conveying pipe 408 from the ash discharge port 407 at the bottom of the dust removal and filtration bin main body 402 and is discharged from the dust removal and filtration bin main body 402 under the action of the externally connected compressed air purging gas source to achieve the effect of continuous automatic slag discharge. When it is necessary to disassemble and clean or replace the hollow cylindrical filter element 413, only need to open the fixing parts 419 at the top of the dust removal and filtration bin and take out the hollow cylindrical filter element 413 to clean or replace it. Rotating the top fastening lock 423 can make the top seal lock move up and down as a whole along the fastening limit connecting rod 422. When it moves to the appropriate position, the top seal locking fixed position plate 426 will fit or separate from the dust remover seal fastening fixed position plate 418; continue to rotate the top fastening lock 423 to move the dust remover seal fastening fixed position plate 418 up and down, which can make the "concave circle" rubber gasket 414 of the sample hollow cylindrical filter element 413 fit tightly or stress-separate from the conical lock groove 411. When the conical rubber gasket 412 is in tight fit with the conical lock groove 411, the top seal fastening plate 421, the top thickened rubber sealing ring 420, and the fixing parts 419 at the top of the dust removal and filtration bin are also designed to be in a just-tight-fitting state. Therefore, by adjusting the top fastening lock 423, the device can be sealed or separated. The fastening lock connecting rod 416 and the fastening connecting rod locks 417 at the upper and lower ends of the hollow cylindrical filter element 413 are both provided with fastening threads; by respectively rotating the eight fastening connecting rod locks 417 at the upper and lower ends of the four fastening lock connecting rods 416, the fastening or loosening of the hollow cylindrical filter element 413 can be achieved, so as to realize the fastening seal or disassembly and replacement of the hollow cylindrical filter element 413.
