Abstract
A method for removing residual filter cakes that remain adhered to a filter after typical particulate removal methodologies have been employed, such as pulse-jet filter element cleaning, for all cleanable filters used for air pollution control, dust control, or powder control.
Claims22
A method for removing residual particulate matter from a filter, the method comprising:
- removing an adhesive substance from the filter together with at least a portion of the residual particulate matter positioned between the filter and the adhesive substance, wherein the portion of the residual particulate matter is adhered to the adhesive substance, and wherein removing includes unaided slough off of the portion of the residual particulate matter adhered to the adhesive substance or includes slough off of the residual particulate matter adhered to the adhesive substance aided by a filter cleaning mechanism.
A method for removing particulate matter and residual particulate matter from a filter, the method comprising:
- applying an environmentally friendly adhesive substance to a surface of the filter including the residual particulate matter, such that the residual particulate matter is positioned between the environmentally friendly adhesive substance and the filter;
- and
- removing at least a portion of the residual particulate matter from the filter by removing the environmentally friendly adhesive substance from the filter surface, wherein removing includes unaided slough off of the portion of the residual particulate matter adhered to the adhesive substance or includes slough off of the residual particulate matter adhered to the adhesive substance aided by a filter cleaning mechanism.
A method for reducing residual filter drag for a filter having residual particulate matter on at least a portion thereof, the method comprising:
- removing an adhesive substance from the filter, in which the residual particulate matter is positioned between the adhesive substance and the filter, wherein at least a portion of the residual particulate matter is adhered to the adhesive substance such that it is removed with the adhesive substance, and wherein removing includes unaided slough off of the portion of the residual particulate matter adhered to the adhesive substance or includes slough off of the residual particulate matter adhered to the adhesive substance aided by a filter cleaning mechanism.
