Wet Scrubber

Product Details:

• Bag filter comprises an arrangement of Bags, made up of special fabric, capable of bearing the operating temperature of up to 220 degree Celsius.
• The design of Bag Filter heavily relies on the Air to Cloth Ratio as per the composition (type of fuel used) and flow of flue gases. , the gas flow through a compartment is stopped temporarily when the pulse cleaning of the bags is to be done in that compartment. 
• The dust dislodged from the bags settle easily in the hoppers because of the absence of any counter-current gas movement in this compartment. The dust so collected is discharged from the hopper through the rotary airlock valve. During this time the remaining compartments keep filtering the gases as usual. Each compartment is cleaned one after another in this manner.
• The starting & stopping of gas flow through individual compartments is achieved through a compact pneumatically operated poppet damper system located at the outlet of each module. While the pulsing in individual compartments are controlled by means of a compartment sequential controller. The pulse of compressed air is controlled by series of pulse solenoid valves that are placed on air reservoir. These in tum are connected to compartment manifold pipe, which open above the venturi of each bag in that row. The diaphragm of the pulse valve is closed as the compressed air is trapped between diaphragm and solenoid valve orifice. When the solenoid valve is energized through an input signal from the sequential controller, the trapped air flows from the top of the diaphragm through the orifice of the solenoid valve. The inflowing compressed air lifts up the diaphragm and flows through the outlet of the pulse valve. Again when the solenoid valve is de-energized, the air gets trapped, closing the diaphragm as a result of pressure equalization. The next adenoid valve gets energized and the entire process is repeated sequentially in cycle 
• The next solenoid valve gets energized and the entire process is repeated sequentially in cycle Solenoid Pulse Valve Poppet Damper 
• RAV (Rotary Airlock Valve) RPM: The rotary air lock valve maintains an air seal preventing its passage into the hopper from below.
