In the prior art, each filter element 51 is provided as shown in FIG.
A backwash air injection nozzle 58 is arranged at each upper open end of the compressed air supplied from the compressed air supply device 60 through the air supply conduit 59 to each ceramic filter element.
Eject into 51. The jetted compressed air increases the pressure in the ceramic filter element 51, and a part of the compressed air flows in the exhaust gas introduction chamber 55 in the direction opposite to the exhaust gas through the fine holes formed in the ceramic filter element 51. As a result, most of the dust adhering to the outer surface of the ceramic filter element 51 is peeled off and falls to the lower part of the exhaust gas introducing chamber 55, and the fallen dust is further discharged from the dust outlet 56 formed at the bottom. Ejected and removed.

ス中のダスト濃度が測定される。1 and 2 show an example in which the filter elements are arranged in a grid pattern in the dust collector body. In FIG. 1, a vertical row in the drawing is an A row and a horizontal row is a B row. In the figure, each of the rows A and B has six rows. Below, for each row, valve A 1 9, valve A 2 10, ... valve A 6 14
Each A 1 rows of columns having, A 2 columns, ...... A is called the six columns, similarly the valve B 1 15, valve B 2 16, ...... valve train respectively B 1 with B 6 20
Row, B row 2 , ... B 6 row. As shown in FIG. 2, the filter element 1 has its upper end opened to the upper space of the dust collector body 2 and is attached to the tube plate 21 by bolts or the like.
At the upper end openings of all the filter elements 1, as shown in FIG.
Has been inserted. The A group detector tubes have their own A for each row.
Is communicated with a group branch pipe 22, and further communicates the valve A 1 9, such as group A branch pipe 22 and each of the solenoid valves, the valve A 2 10, the group A sensing main pipe 5 through ...... valve A 6 14. Similarly to the A group detection pipe 23, the B group detection pipe 25 is also grouped into each row and communicates with the B group branch pipe 24, and each B group branch pipe 24 further has its respective valve B 1 15, valve B 2 16, ...
... communicates with the group B detects main 6 through valve B 6 20. The A-group detection main pipe 5 and the B-group detection main pipe 6 are combined into one via the A-group main valve 7 and the B-group main valve 8, respectively, and communicated to a predetermined position through the dust concentration measuring device 3 and the suction fan 4. (When the pressure of the gas in the dust collector body 2 is sufficiently higher than the atmospheric pressure, the suction fan 4 may be omitted.) Next, a method of detecting abnormality of the filter element 1 by the above device will be described. First, in the case of performing detection from the group A in FIG. 1, the group A main valve 7 is opened and the group B main valve 8 is closed during the non-backwashing process of the filter element 1 (the same applies hereinafter). Next, valve A 1 9 is opened and valves A 2 10 to A 6 14 are all closed. As a result, the filter element 1 in FIG.
Only the two A 1 rows have their internal gas sucked by the suction fan 4, and the dust concentration in the gas is measured by the dust concentration measuring device 3. Then close valve A 1 9 and open valve A 2 10 only. At this time, all other valves A 3 11~A 6 14 and B group main valve 8 holds the state of all closed. As a result, the gas in the four filter elements 1 in the A 2 row is sucked, and the dust concentration in the gas is measured.

B 6 columns, measuring the dust concentration of the gas in the filter element 1 in each column. In this way, the dust concentration of the gas in the filter elements 1 in all the rows is measured, and after the measurement, the inert gas or compressed air is fed into each detection pipe as needed. Backwash and clean the piping system inside the detector, close all the valves in the detector,
The suction fan 4 is stopped.
