Dust collection device and method for detecting rupture of filter in dust collection device

Abstract

A dust collection device (1) is provided with a dust-containing air chamber (12) into which dust-containing air suctioned by a blower (23) is introduced, and a blower (23) for blowing air into the dust-containing air chamber (12), a filter (15) that allows the dust-containing air to pass therethrough and separates dust from the dust-containing air (10); a clean air chamber (21) which is separatedfrom the dust-containing air chamber (12) by the filter (15) and into which the clean air filtered by the filter (15) is introduced, the clean air chamber (21) being provided with a filter (15); and apulse jet dust removal mechanism (25) that removes dust adhering to the filter at predetermined time intervals, the dust collection device (1) being provided with: a dust detection sensor (31) that is disposed on the clean air chamber (21) side and that transmits a dust detection signal when dust is detected; and a determination processing unit (33) that determines that breakage of the filter (15) is detected when the dust detection signal is received at a timing different from the predetermined time interval.

Description

technical field [0001] The invention relates to a dust collection device and a damage detection method for a filter in the dust collection device. Background technique [0002] Conventionally, for example, in factories, dust collectors have been used for the purpose of collecting dust from dust-containing air discharged from production activities and the like. [0003] As a dust collector, various methods are used, such as a method of separating dust from the air by gravity, a method of separating dust by centrifugal force, etc., but among them, the air containing dust is filtered through a filter. And the way of separating dust is especially widely used. [0004] In a dust collector that separates dust with a filter, if the filter is abnormal, the dust cannot be separated normally. Especially when the filter is damaged, the dust-containing air will flow out to the place where the clean air from which the dust has been separated is supposed to be discharged, thereby pollut...

AI Technical Summary

Problems solved by technology

That is, especially in a dry dust collector that collects dust in a dry environment, if dust containing high-temperature substances such as sparks is inhaled, a fire may occur inside and the filter may be damaged.
