The purpose of this invention is to provide a pleated-type filter used for an apparatus for collecting dust that is optimally designed and to provide the apparatus for collecting dust using the filter, wherein the pleated-type filter can keep the resistance to its ventilation low when the filter is installed in the apparatus for collecting dust so that the pleats are directed vertically, and wherein the area for installing the main bodies of the pleated-type filters can be reduced as much as possible. The ratio of the apertures of the pleats (P/H) that is defined by the intervals (P) between the crests of adjacent pleats of the main body and the heights (H) of its pleats ranges from 0.1 to 0.3. The ratio is determined based on the relationship between the area for installing the pleated-type filters and the ratio of the apertures of the pleats (P/H). This is done by using the resistance to ventilation of the contaminated filtering cloth, which resistance corresponds to a coefficient of resistance that is caused by a filtering cloth and residual dust that cannot be shaken off from the filter by means of the shaking-off operation.

Apparatus for collecting dust and a pleated-type filter therefor

An apparatus for collecting smoke and dust with a deodorizing function which has excellent capability for maintenance and an improved deodorizing and silencing effect, the apparatus having a housing and a bulkhead having an opening and disposed in the housing to separate a space for deodorizing and filtering exhaust gas from a space for discharging exhaust gas, a vacuuming device for vacuuming exhaust gas disposed in the space for discharging and communicating with the opening of the bulkhead, a filtering device for filtering exhaust gas disposed in the space for deodorizing and filtering and communicating with the vacuuming device through the opening of the bulkhead, and a deodorizing device for deodorizing the exhaust gas concentrically disposed at an outer side of the filtering device.
