Description

The HNTS product line offers state of-the-art cleaning power and dust collection capacity. Designed to collect process-generated metal laden dusts. Featuring roof explosion panels, inlet deflection, reverse pulse jet cartridge filter cleaning and collected dust extraction via a suitable vacuum system (Not included)

DESCRIPTION AND OPERATION

  • The HNTS Dust extractor is a high-efficiency, cartridge dust collector designed to eliminate airborne dust as it is generated. Contaminants are captured at the source(s), 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 on-line or downtime cartridge filter cleaning by means of a customer supplied compressed air system. This is a high-efficiency, horizontally oriented cartridge dust collector equipped with 13" (330mm) 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. 

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 down toward the hopper where the heavier particles discharge to the dust exit port. 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 become 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 exit port. 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 downward into the dust exit port.
