Jet Pulse Filter

Jet Pulse Filter
Pulse jet bag filter, also called pulse jet filter or pulse jet dust collector, is a self-cleaning dry filtration system. The pulse jet dust collector cleaning system removes particulate matter and dust from the surface of the internal filter media with bursts of compressed air. Pulse jet bag filters are the most common type of particulate air pollution control equipment found in workplaces, including factories, plants, warehouses, and other industrial or commercial environments, to meet workplace air quality safety requirements and comply with EPA requirements for emissions.
Cet Pulse Filter Scope
CPE Filters, Inc. designs and manufactures pulsed jet bag filter systems and custom components for a wide variety of industrial environments. The pulse jet dust collector has no moving parts, so it offers reliable continuous operations combined with superior filtration efficiency, designed to effectively collect and remove potentially harmful particulate matter gas fumes that may enter the working environment or atmosphere. The popularity of the pulse jet dust collector is due to its ease of use, low energy use and minimal maintenance requirements.
Pulse jet bag filters get their name from the short bursts or "pulses" of compressed air used to clean the bag or filter. In the pulse jet system, dust collects on the outer surface of the bag/filter where it usually forms a dust cake. When the dust cake is of a suitable thickness, based on time or pressure drop, a controller activates a sequential pulse of compressed air into the interior of the filter bags, one (or more) rows/rows at a time, striking the dust and dust cake escaping from the filter by gravity. to fall into the hopper. The mechanics of the compressed air pulse and the associated induced draft of additional air through a venturi nozzle create a shock wave and ripple effect on the filter bags, increasing the mechanical strength of the initial burst of compressed air.

Advantages
Pulsed jet filtration systems offer several advantages over other dust collection systems. The main advantage is the on-line cleaning ability of the pulse jet. The duration of the compressed air pulse is typically in the range of 100 to 200 microseconds, effectively facilitating 24/7 operations with no interruption in the ventilation of dusty air and no shutdown time to clean the bag filters.
