The DUST-HOG Supra-Blast product line offers state-of-the-art cleaning power and dust collection capacity. Designed to collect process-generated dust, Supra-Blast is the first centralized cartridge dust collector with UAS’ exclusive air distribution insert within the cartridge filter and QuickSeal filter access doors. Distributed originally by United Air Specialists UK Ltd

Description and Operation

The DUST-HOG Supra-Blast is a high-efficiency, cartridge dust collector designed to eliminate airborne dust as it is generated. Contaminants are captured at the source(s) and then conveyed through ductwork to the cartridge filter section (dirty air section) where the dust is collected. Clean air is then discharged from the unit through the clean air discharge. The dust collector is designed for online or downtime cartridge filter cleaning using a customer supplied compressed air system. The Supra-Blast is a high-efficiency, horizontally oriented cartridge dust collector with 15" (38 cm) outside diameter cartridge filters. The larger diameter Supra-Max Series cartridge filter design allows for lower pressure losses through the dust collector while increasing the amount of media contained in each filter. DUST-HOG Supra-Blast Series dust collectors have pre-engineered backward-inclined or radial-type optional blower packages in 3, 5, 71 /2, 10, 15, 20, 25 and 30 HP (2.2, 3.7, 5.5, 7.5, 11, 15, 18.5 and 22 kW) assemblies. There are two primary modes of operation — the air filtering operation and the filter cleaning cycle. Both modes of operation are shown in Figure 1. in the manual.

Air Filtering Operation

The contaminated airstream is drawn into the dust collector where its velocity is reduced by inlet baffle plates to provide even air distribution across the entire surface area of the cartridge filters. This design enhances filtration efficiency by establishing a uniform “dust cake” on the filters. The airstream is then directed around the cartridge filters and toward the hopper where the heavier particles discharge to the dust storage drum. The contaminated air then passes through the cartridge filters. The filter media strips the dust from the airstream allowing only clean air to pass through the cartridge filter. The air then passes into the clean air plenum, through a blower package and is discharged from the unit.

Filter Cleaning Cycle 

During normal operation, the surface of the cartridge filters becomes loaded with contaminants. The reverse pulse cleaning mechanism provides brief bursts of compressed air, directed through the diaphragm valves, toward an air distribution tip and into the centre of the cartridge filter. This pulsing action dislodges the collected particles from the media where they fall into the hopper and are discharged to the dust storage drum. During the cleaning cycle, each row of cartridge filters is cleaned individually. The solid-state sequential timer actuates a solenoid valve, which allows an air diaphragm valve to open for approximately 100 milliseconds. High-pressure air from the air manifold reservoir is directed through the diaphragm valve toward the air distribution tip mounted on the tube sheet in front of the cartridge filter. The air is then directed into the cartridge filter. The filter’s air distribution insert maximizes the compressed air energy to increase the amount of collected dust released from the filter surface. The dislodged dust removed from the filter is swept down into the hopper. The remaining filters are cleaned sequentially. The original sequencing is factory set at 10-second intervals and is adjustable to adapt to your particular cleaning needs.

How do Dust Extractors Work?

Dust collection systems work in a variety of different ways but all have general principles in common. They draw process dust and particulates from the air through a filter that first captures and separates the matter, and then discharges decontaminated air back into the workplace or environment.

Dust extractors are used in many different and varied industries and so different demands are made of them; however all have common components such as a blower (or fan), dust filter, filter cleaning system, dust container and dust removal system.

Five common types of dust collection equipment are fabric filter baghouses, inertial separators (like mechanical cyclones), cartridge collectors, wet scrubbers, and electrostatic precipitators.

Importance of Dust Extractors

Dust in the workplace can affect product quality and employee´s health. Having a dust-free environment is essential to the health and safety of the workforce. Not only does it affect the health of employees but the dust covers the equipment affecting production processes and quality of the products. 

Capturing the dust at the source prevents it from spreading, done by using a dust extractor system to facilitate the important housekeeping to avoid it from accumulating.
