Title: Low-noise air pulse dust collector With a built-in conical hat for the prevention of secondary contamination
Inventor: IM HO BIEN
IPC: B01D46/42
Filed: 2018-03-29
Abstract: A low-noise air pulse type dust collector having conical hat-shaped parts embedded therein to prevent secondary contamination of filters of the present invention includes: the conical hat-shaped parts which are installed above dust collection filters to prevent secondary contamination of the filters; and air cylinders which are each installed in filter outlets to efficiently remove dust from the filters. The purpose of the present invention is to reduce transient noise and remove dust attached to the surface of the filters effectively and efficiently by closing each of the filter outlets and applying an air pulse to the inside of each of the filters in order to effectively remove dust attached to the filters with a small amount of air compared to existing pulse type dust collectors. The existing air pulse type dust collectors greatly reduce efficiency of the filters by arranging the filters in multi-stages inside the dust collectors such that dust having been dedusted and flown down from upper filters is accumulated on top portions of lower filters. A high pressure and a large amount of air should be applied during injection of air pulse since the dust on the top portions of the filters are not removed well. In a low-noise air pulse type dust collector of the present invention, the conical hat-shaped parts are installed above the lower filters so that dust removed from the upper filters is not flown to the top portions of the lower filters. According to the present invention, the low-noise air pulse type dust collector has the same dust removal efficiency although amount of air applied to the air pulse is reduced as much as about 20% when the conical hat-shaped parts are installed (FIG. 1). The existing air pulse type dust collectors generate a loud noise by applying pulse of an intermediate pressure (about 6.5 atmospheric pressure) to the inside of the dust collectors. The low-noise air pulse type dust collector of the present invention has a high dust removal effect and an effect of greatly reducing noise by blocking each of the filter outlets with air cylinders during injection of air pulse in order to reduce noise and increase effect of removing dust, and even by applying air amount of about 80% compared to the existing air pulse type dust collectors to one filter (60, 70 of FIG. 5 in which the filter outlets are blocked when applying air pulse to the filters of FIG. 6).
