Bag cleaning is achieved by channeling a surge of atmospheric air, in the reverse direction, through the bag, causing the bag to expand.
Install a primary dust collector prefilter to reduce dust loads to the baghouse. Pressure drop through a baghouse is caused due to the air flows resistance when air passes through the filtering bag and the filter cake. A baghouse, bag filter, or fabric filter is an air pollution control device that removes particulates out of air or gas released. Advantages of cleaning without a venturi in baghouse. Air losses reduce the necessary airflow at the process capture point moisture can lead to excess coating. For cleaning of high temperature gases reverse air bag houses are widely used in the industry. Baghouses best dust collector system baghouse america. Shaker fabric filter collectors clean the bags by gently shaking them. Some pressure losses due to friction also occur as the gas stream moves through the baghouse. This course discusses the cleaning mechanisms used in the three main baghouse designs shaker, reverse air, and pulse jet. Should you convert your antiquated baghouse to a pulse jet. While the reverse jet with venturi does provide some advantages when compared to other methods such as reverse air. Baghouse america manufacturers baghouses and ships them all over the globe. Air pollution is the introduction into the atmosphere of chemicals, particulates, or biological matters that cause discomfort, disease, or death to humans, damage other.
Reverse air simply indicates a reverse flow high volume low pressure air to clean the dust cake off the bag surface. Fabric filters may be used standalone or integrated in dry flue gas desulfurization dfgd solutions. Sometimes, changing the design of your baghouse can provide dramatic improvements to the efficiency of your baghouse operation without the need to replace all of the equipment. Some reverse air baghouses employ a supplemental shaker system to assist cleaning by increasing the amount of energy delivered to the bag. Dirty gas flow normally enters the baghouse and passes through the bag from the inside, and the dust collects on the inside of the bags. Contaminated gas enters the baghouse inlet manifold and is distributed to each hopper, from which it enters the filter bags through collars in the tube sheets. Typically, the pressure drop is expressed in inches or centimeters of water. In a pulse jet baghouse dust collector, contaminated air enters the lower portion of the baghouse filter housing and passes through the highly efficient media filtration bags and out through the top of the baghouse.
The donaldson torit lp baghouse dust collector provides superior bag filter cleaning performance in a reverse air design. A dust collection system needs to be sealed to prevent air losses and moisture entering the system. Also, both of these cleaning styles will only work if the baghouse is first taken offline and the dustladen process air or gas flow is stopped from entering the baghouse. The most common methods of cleaning are shaking, reverse air, and reverse pulse or pulse jet. Dust collector systems by baghouse america are shipped all over the globe.
