Spray scrubber (wet srcubbing)
SR-100
Techne Calibration
The unit is designed to reduce concentrations of Hydrogen Halides (Chloride and Fluoride) produced by the decomposition of Halogenated polymers such as PVC and PTFE.
The SR-100 unit is designed to remove 95% of HCL in the exhaust gas so that as long as the scrubber is not overloaded by burning off too large a quantity of PVC the emerging gasses will contain a quantity of HCL low enough to be safely vented to the atmosphere.
The unit operates by passing the scrubbing liquid through a nozzle which produces a hollow conical spray in the venture section. The nozzle and venture section are designed so that for a given quantity of scrubbing liquid, the maximum absorbing surface area of liquid is presented to the gas.
Additionally the action of the spray produces a motive force sufficient to induce the gas into the scrubber, thereby reducing the overall unit pressure drop.
The gas and spray mixture then enters the separator / liquid storage vessel where the scrubbing liquid and its absorbed acidic contaminants are separated from the cleaned gas by centrifugal force. The clean air then passes through a demister section to remove the remaining droplets.
Scrubbing liquid is re-circulated through the system and clean make up water or caustic solution is added in accordance with the quantity of noxious elements absorbed.
