The
HCW bag filter incorporates an
"offline" filter fabric regeneration technology (during the regeneration process, the treated air flow through the filter fabric is cut off). The filter fabric is regenerated by means of a travelling system equipped with a medium pressure fan. It is installed on carriage, which by means of a special seal cuts off both filter cartridges to be regenerated and the adjacent rows of bags – this principle of operation is similar to the one applied in HCW-type filters regeneration. This regeneration system encourages a considerably
lower emissions level than in the case of “online” solutions and at the same time
extends the life of the filter fabric.
The presented regeneration system makes it a perfect solution, when strictly low dust emission levels are to be complied with or if no compressed air installation is available. Since no compressed air is used, the filters prove to be a significantly cost-effective solution. HCW filters standard filtration area may range from
232 to
11,000 m2.
