(1) consists of a bag-like filter element having an open end (2) and a flow path (3) for dust-containing air. This pocket is made up of a large number of parallel headers arranged in parallel, each with its open end (2) fixed to a common header (4) with adhesive. The filter element of the polynet (1) is composed of a filter medium (5) and a thin non-woven fabric (6), and the non-woven fabric (6) covers the outer surface of the filter medium (5).
is protected. As shown in Figure 2, the pocket flow path (3) is formed by sewing the opposing filter media (5) with sewing thread (8), and the sewing is performed at positions where the +l+ = J method of the pocket is evenly divided. What is the flow path (3)?
They have almost the same shape, and the opposing filter media (5) are in contact with each other at the sewn portion. &l header (4)
This is done continuously from a more appropriately distant position to the end of the pocket, and a loop (for hanging the pocket) is provided at the end of the pocket.
9) is attached.

Normally, dust-containing air is evenly distributed and sucked through each opening end (2) provided in the header (4), and the dust-containing air is sucked into the pocket (1).
The filter medium (5) passes through each flow path (3) provided in the
The dust is collected in the flow path (3). but,
This type of pocket filter has a pressure of J
Under low loss conditions, even if the rated air flow is applied, the
' There are cases where the tube L is not well bulged and the dust-containing air only flows into some pockets.
Even if the pressure loss increases, some pockets remain where λ dust air does not flow. Furthermore, even under normal conditions, if a pocket swells, it will come into contact with the adjacent pocket and restrict the flow of dust-containing air and filtered clean air, making it impossible to use the entire area of the filter medium effectively and increasing pressure loss. This reduced the amount of dust retained and shortened the life of the filter.

ストを捕集可能にして。The present invention solves the above-mentioned problems by alternately combining sewing threads, providing passages of at least two different sizes, and further altering the stitching start positions of the sewing threads in these passages. By making these differences, even when pressure loss is low, each pocket flow path can be completely inflated and dust can be collected on the entire surface of the filter medium.

(11) is a pocket attached to the support frame (work 2) and incorporated into the header (131).The pocket support frame (12) is mechanically caulked with the adjacent pocket support frame (12) and fixed tightly. The pocket (1) is composed of a filter 14 (14) and a thin nonwoven fabric (15), and the nonwoven fabric C5) covers the outside of the filter medium (14) to protect it. are doing. Pocket (11) has sewing thread +161. (IIl+
), the dust-containing air flow paths (17), (17'), (1

) with long slack (approximately 3b/m)
and one with short sag (approximately 25 steel/m>).
By alternately combining the pockets (11) in the vertical direction, the cross-sectional shape of the pockets is made complicated with unevenness, as shown in Fig. 5, and the dust-containing air and the filter material (14) are reduced compared to conventional ones. It is designed to be shaped so that it can be easily contacted so that dust can be collected uniformly throughout the filter medium (14).

), the second widest channel (17) from the top and bottom ends, and a narrow channel (17") in the center of the pocket. Also,
The sewing thread (1G') with a short slack is sewn into the sewing thread (16) with a long slack from a position further away from the header (4).

長寿命を可能にしたものである。The second widest channel (17) from the top and bottom ends, and the narrow channel (17'') in the center of the pocket.
) compared to the header (13), the dust-containing air tends to concentrate in the center of the conventional pocket, and the flow paths provided at the top and bottom of the pocket do not contain the dust-containing air. This eliminates the phenomenon that it is difficult for dust to flow in, and allows dust-containing air to flow uniformly into the entire pocket. As a result, the entire area of the filter medium (14) is effectively utilized, and dust is evenly captured by the filter medium (14). This results in lower pressure loss, higher dust retention, and lower dust retention than conventional filters.
This makes long life possible.
更に、含塵空気が流入することにより広い流路（１７）

態においても、定格風量に満たない風量の場合でも、ポ
ケット（１１）を自立させることが出来るものである。Furthermore, the flow path (17) is wide due to the inflow of dust-containing air.
The pocket (11) can be made to stand on its own even in a state where the pocket (11) is greatly swollen and has a low rolling pressure loss as it becomes the core, and even when the air volume is less than the rated air volume.
また、隣合せのポケット（１１）の流路間には隙間が生
じ、従来ボケ、ソトがふくらんだ場合。In addition, if a gap is created between the channels of adjacent pockets (11), and the conventional blur or soto swells.
隣合ゼのポケットと接触し含塵空気及び濾過された清浄
空気の流れを制約し。Contact with adjacent pockets restricts the flow of dust-laden air and filtered clean air.
圧ツノ損失を上昇させる原因となっている点を解消した
ものである。This solves the problem that causes the pressure horn loss to increase.

大なるものである。In this way, the present invention makes it possible to effectively utilize the entire area of the filter medium by simply changing the conventional method of sewing threads, and achieves a high dust retention amount and a long service life. Furthermore, the practical effect of making the pocket independent is enormous.
