Multi-channel pockets were designed by PRAT DANIEL in the seventies. Since then this firm, which has changed its name to AIR INDUSTRIE, PROCEDAIR and SOLIOS, has continued to manufacture bag filters with these pockets.
Their special design calls for high-precision manufacture, for which ICT FILTRATION has made a considerable investment in technology to be able to take on a specific manufacturing process to assure measurements and the best possible value for money.
Eco-efficiency
- Maximum performance over a long life cycle.
- Reduction and control of emissions.
- Products meeting market standards.
- Manufacturing to order.
- Boosting the efficiency and performance of facilities.
Uses
The industry that makes the most widespread use of multi-channel pockets is primary aluminium production, as part of its electrolysis process. Firstly because this eliminates the risk of the fluorine gas produced in this process being emitted into the atmosphere. Secondly because it allows as much as possible of this gas to be re-used in the production process (fluorine combines with alumina to produce enriched alumina, the raw material for primary aluminium).
Manufacturing system
Qualities and treatments
The design of these bags has stuck to the multi-channel approach, but changed the number and separation of the channels, as well as the length of the bag. ICT FILTRATION has manufactured up to fifteen different models, from the oldest with 19 and 9 channels up to the most modern with 22, 29 and 32 channels.
The bag cleaning system has moved on from pulsed counter-flow air to low pressure counter-flow, via “Plenum Pulse” compressed air. In fact, the fabric used varies depending on the cleaning system. Chemical conditions, humidity and the way of working also determine fabric quality.
