- a number is provided. Further, each of the air ejection nozzles 55a, 55a has its tip inserted into the clean gas chamber 54, and is positioned opposite to the opening 52a of each of the ducts 52, 52.
- Reference numeral 56 denotes a detachable inspection lid, which also serves as a partition member for separating the dust removal chamber 51 and the clean gas chamber 54.
- Reference numeral 57 is a detachable inspection lid.
- dust-containing gas is introduced into the dust-removing chamber 51 from the inlet (not shown) through the gaps 58, 58 by a suction action of a suction means (for example, a blower) (not shown) communicating with the clean gas chamber 54. Is flowed in.
- the dust-containing gas that has flowed into the dust removal chamber 51 flows into the filter 53b from outside the filter 53b. At this time, dust in the dust-containing gas is removed by adhering to the outer surface of the filter 53b.
- the gas that has flowed into the filter 53b flows as a clean gas into the ducts 52, 52 through the openings 53e of the finoletor 53b, and from the openings 52a of the ducts 52, 52 into the clean gas chamber 54. Is flowed in. Then, the clean gas flowing into the clean gas chamber 54 is sucked by suction means (not shown) and discharged out of the apparatus.
- the filter 53b is appropriately backwashed.
- the backwashing of the filter refers to the opening force of the filter in order to eliminate the clogging of the filter due to dust attached to the outer surface of the filter due to dust collection. This means that dust adhering to the outer surface of the filter is removed by passing compressed air from inside to outside. The backwashing of the filter 53b will be described in detail.
- the dust separated from the outer surface of the filter 53b due to the backwashing of the filter 53b falls downward and is collected by a hopper (not shown). Then, the dust collected in the hob is discharged to a receiving box (not shown) as appropriate.
- FIG. 21 (a) shows an example in which the other ends of the ducts 52, 52 are bent by 90 degrees and the openings 52a are directed downward, and the tips of the air ejection nozzles 55a, 55a face the openings 52a. Is placed.
- FIG. 21B shows an example in which the ducts 52 and 52 are arranged to extend in the vertical direction, and the clean gas chamber 54 is arranged to extend in the horizontal direction.
- the front ends of the air ejection nozzles 55a, 55a are located opposite to the openings 52a of the ducts 52, 52, and the flat plate type cartridge elements 53, 53 are arranged such that the filter 53b extends in the horizontal direction. That is, the continuous chevron-shaped top lines formed by the pleated filter media 53a are arranged so as to form horizontal stripes.
- the force using flat plate type cartridge elements 53, 53 as the cartridge element is not limited to this.
