Over a hundred years of history bag house applications, its biggest advantage is the high collection efficiency (up 99.99%), emission concentration up to 10mg / m3 or less, and also high efficiency rating of 2.5μm or less fine particles may also have a good collection efficiency, and therefore widely used. But after years of bag […]

Even minor rips, holes, and tears in the bags can lead to exceeding emissions limits. In many plants, such a problem will cause an emissions spike, becoming a “reportable event”, with possible fines and sanctions from regulators as a consequence. Additionally, any baghouse malfunction has the potential for causing plant-wide problems, that may lead to […]

There are three ways damaged or corroded cages cause filters to fail: When pulsed bent cages can cause the filters to rub against each other or against the sides of the collector causing the bags to tear open Bent, twisted, or broken cages will have many sharp edges that can cut holes in the fabric […]

Weaving is a method of fabric production in which two distinct sets of yarns or threads are interlaced at right angles to form a fabric or cloth. The other methods are knitting, lace making, felting, and braiding or plaiting. The longitudinal threads are called the warp and the lateral threads are the weft or filling. […]

These are characterized as having the best cake release, the highest flow rates, less likely to blind, and by comparison would have the poorest retention (filter efficiency). The yarns are measured in terms of mil diameter, for example, 6 mil diameter yarns, 8 mil diameter, 12 mil diameter, 15 mil diameter, etc. The larger the […]

Filtration is the separation of a fluid-solids solution involving the passing of this mixture through a porous barrier which retains most of the solid particulates contained in the mixture. The various terms used in filtration processes include: Media – the filtration cloth or barrier to collect the solids, Liquor – the solution containing the liquid […]

In a reverse air baghouse, the dirty air flows from the inside-to-outside, so that the dust collects on the inside of the filter bag. The filter bags are tubular, open at the bottom and connected to a tubesheet. They are supported from the top through a spring or J-bolt suspension system. The gas flow is […]
