Title: Dust collecting filter cloth
Inventor: NOJIRI HIDEO
IPC: B01D39/16
Filed: 1983-05-31
Abstract: PURPOSE:To obtain filter cloth developing excellent backwashing effect, by applying heat treatment due to a flame to the gas inflow side surface of filter cloth comprising a nonwoven fabric made of a thermoplastic synthetic fiber. CONSTITUTION:Filter cloth 1 comprising a nonwoven fabric made of a thermoplastic synthetic fiber, for example, a nylon fiber is sewn to form a pocket part and an air stream containing dust is penetrated into the pocket part from the outside in a direction (a) while purified air is flowed out from the opening part of the pocket part. Dust particles are collected between fibers 6 and the accumulated layer C thereof becomes thick with the elapse of time. When this thickness becomes excessive, filtering pressure loss becomes large and, therefore, operation is stopped and a flame 8 is applied to the surface of the filter cloth 1 from the penetrating side of the dust-containing air stream and slowly moved to a direction (c) so as to lick up the surface thereof. By this method, hair like elongated fibers are softened, bent and collapsed by the heat of the flame or melted and flowed down toward unmelted fibers to partially close the gaps between fibers. The treated surface of this filter cloth is smooth as compared with that prior to treatment and, if backwashing is performed, the dust accumulated on the surface of the filter cloth can be removed almost perfectly.
