Pisa Chang Zhou General Machinery Co. Ltd.

JiangYIN, China

We are one of reliable names engaged providing the best FDC Type Bag Filter. The FDC Type Bag Filter is cassette-type filter fitted with stationary compressed-air vessel flexible compressed-air hose and fixable nozzle. FDC Type Bag Filter is designed to deliver optimum performance at low operating cost. FDC Type Bag Filter with compressed air cleaning is more appropriate in some special cases.

Construction and Principle : The compressed-air pipes with the nozzles to the slotted plate is installed in front of the filter bags.The vessel is symmetrically arranged along the horizontal direction of the filter bags in the filter chamber. Along the row direction of the filter bags is uniformly mounted a row of solenoid valves in the vessel. The filter cleaning cycles will start and be controlled by a pulse instrument control installed in the control cabinet.

We bring forth modular cassette-type FSC Type Bag Filter with reverse air blowing. FSC Type Bag Filter is an efficient solution for reducing residual dust values. FSC Type Bag Filter is designed for small, compact units and then large turnkey. FSC Type Bag Filter is made using robust material for durability. Customers can contact us for further details.

Advantages :

• BIZA modular filters can be designed and built both small , compact units and then large turnkey
• Filters can be easily integrated into customers’ existing plants or buildings with small space due to their customized sizes.
• The filters are constructed in the horizontal arrangement of the filter elements and easily access.
• The filters with reverse air cleaning run in low energy consumption due to their economical around “self-sufficient” filtration.
• A cleaning fan generates the cleaning air without an additional compressed-air unit.
• The FSC filter bags can be easily exchange only by one person without any other tools.
• The structure is usually welded between different parts instead of being screwed or bolted thus reliable sealing can be reached. The key sealing between dirty and clean air compartments is particular.

Construction and Principle :

FSC filter comprises the hood for dust-laden gas, the filter casing, the dust collection hopper with support structure and discharge unit.
The filter casing comprises two separated chambers individually containing dust-laten gas and clean-gas with filter-cleaning device. The filter bags are arranged horizontally in the dirty gas chamber via the slots with open side to clean air . The connection with the slotted wall by a clamping frame with leg springs is air-tight. The slotted wall separates dirty gas and clean gas.
The dirty gas is extracted into top hook of filter casing, then flows down through the filter bags into the clean-gas chamber. The filter cleaning device cycle starts when the specified differential pressure is reached in the filter casing or the pre-set time has expired. The adhering dust to the bags is removed by reverse cleaning air then falls down to the collecting hopper and will be transported to the waste container or big bags via discharging screw conveyor or other removal device.
The filter adopts off-line cleaning method, nozzles along the vertical arrangement covers three adjacent rows of slots and the filter bags behind them . During every dust removal cycle , the filter chamber will be isolated among the main air flow by setting the air inlet or outlet valve, .This process will last about 23min.Although this way will reduce the effective filtration area, but has the following advantages :

• The consumption of high voltage pulse air volume is not great with effectively cleaning, and the low pressure.
• The removed dust from the filter bag surface have enough time to fall down.it has very small probability to be thrown.
• The cleaning frequency decreased, the service life of the filter bag is prolonged
• Valves demands can be reduced and the original investment will be saved .The maintenance work will be less.
• High efficiency of dust removal, dust collector can maintain a low pressure drop, saving energy and reducing consumption
