2. Description of the Related Art A self-cleaning dust collector is known, for example, from Japanese Patent Laid-Open No. 63-93318. There, pulsed jet air is ejected from the outlet opening of the filter to remove dust.However, in the area near the outlet opening, the jet air passes through the inner space of the filter, so sufficient desorption is performed only on the far end side of the filter. No dust effect can be obtained. When the venturi is loaded into the outlet opening, the surrounding space of the venturi is in a negative pressure state and tends to draw ambient air into the inside of the filter, so that dedusting in the vicinity of the outlet opening becomes more difficult. This tendency is particularly strong in long hollow filters.

A filter that solves such a problem is already on the market (unknown document). This is because the columnar body is integrally provided inside the filter, the internal volume is reduced by the volume occupied by the columnar body, and the jet air colliding with the upper end of the columnar body is reflected upward to uniformly remove dust. The columnar body is erected from the inner bottom of the cage fitted inside the filter element toward the outlet opening, and the upper end thereof is rounded into a dome shape.

The columnar body is formed as a cylindrical body, and is erected from the inner bottom of the cage toward the outlet opening. Therefore, there is a limit to the length of the applicable filter, 1.5m
It cannot be applied to filters exceeding 0. For example, there is a cylindrical filter whose axial length reaches 7 m. However, in such a long filter, it is inevitable that the columnar body is bent and deformed, and uneven dust removal is likely to occur. By increasing the rigidity of the columnar body,
It is not impossible to avoid flexural deformation, but it is too costly and practically problematic. As represented by a ceramic filter, a shape-preserving filter does not require a shape-retaining cage, but in such a filter, it is difficult to support the columnar body in a vertically long position. Of course, the columnar body cannot be added to an existing filter.

In the long filter as described above, the impact of jet air repeatedly acting on the filter often causes damage to the filter element and the cage for supporting the shape of the filter element. The filter element made of cloth bursts near the bottom of the filter.
In addition, the repeated impact forces cause fatigue failure at the top of the cage, causing the cage and filter element to fall out of the filter mounting wall.

In the state of performing dust removal, the jet airflow A ejected from the dust removal mechanism 6 goes straight inside the filter toward the inner back end. At this time, since the deflector 24 is provided in the filter from the outlet opening thereof toward the inner depth, the jet airflow A moves to the inner depth while colliding with the deflector 24. The impinging jet airflow A is forcibly deflected and guided toward the filter wall to expand the filter element 11 located around the jet wall A, blow off the filter wall 11 and blow off dust accumulated on the outer surface of the filter element 11. Therefore, if the deflector 24 is provided so that the jet airflow A collides with the deflector 24 at a place where it is difficult to remove dust, dust can be uniformly removed.

Next, the operation of the deflector 24 will be mainly described. Jet airflow A ejected from the nozzle 22 during dust removal
Moves straight through the space in the filter 5 at high speed. But,
Since the deflector 24 is provided in the filter 5, the jet airflow A collides with the deflector 26 in the uppermost stage immediately after being jetted into the filter 5 as shown in FIG. While sequentially colliding with the deflecting body 26, it moves to the inner bottom of the filter 5, and finally collides with the shielding plate 28 to be dispersed. The jet airflow A colliding with each of the deflecting bodies 26 during the transition is forcibly changed in direction by the deflecting bodies 26, and a part of the jet airflow A is directed to the filter wall of the filter 5. The deflected airflow causes the filter element 11 around the deflector 26 to rapidly expand, and the airflow blowing through the filter wall also blows off the dust to remove the dust adhering to the outer surface of the filter. Moreover, this detaching action continuously progresses from the side of the outlet opening toward the inside. Therefore, the dust adhering to the outer surface of the filter element 11 can be removed evenly, the filtration surface wall can be regenerated to an appropriate state, and the dust that has once separated can be prevented from reattaching to the filter element 11.

As described above, the jet air flow A is directed to the respective deflecting elements 2
6, it reaches the inside of the filter in a state where its momentum is gradually weakened, but it still has sufficient velocity energy. Conventionally, the jet airflow A repeatedly colliding with the rear end wall 14 damages the cage 12, breaks through the filter element 11, and causes the entire cage 12 to fall off the partition wall 2. Providing a shielding plate 28 on the deflecting body 26 can eliminate such an accident. This is because the shield plate 28 receives most of the energy of the collision. The back end wall 14 is externally fitted and attached to the stringer 16 in order to cover the filter element 11 and is integrated with the stringer 16 only at the welded portion, so that it does not fall off as described above. It was easy to occur. However, in the case of the shielding plate 28, since it is not necessary to take such consideration, since the plate surface can be received by using the stringer 29 and can be firmly integrated by welding, the shielding plate 28 can be removed. There is nothing to do.
