air scrubbers for chemical processes

Independent laboratory tests have shown that many of these units are removing various types of airborne pariculate at efficiencies up to 99.9%, even on heavy particulate loads. A High Volume Water Injector The Monroe Dual Throat Air Scrubber utilizes a high volume wash water injector system that removes airborne particulate by delivering an initial surface inpingement shock to heavy inlet dirt loads. Dual Adjustable Scrubbing Throats High velocity air atomization takes place as the inlet air is directed through the fixed and dual adjustable scrubbing throats. The easily adjustable dual throats balance the pressure drop through the air flow system at the start-up or after system changes are made. This design feature eliminates the need for ductwork dampers and blast gates that are prone to particulate build-up and require scrubbers periodic maintenance. In for addition, the increase in pressure chemical drop in the wash zone improves the overall effciency processes of the system. After passing through the turbulent air and scrubbers dual throat wash zone, the air inpinges on the liquid for surface, changes direction and then continues through deflectors and to a large, double row moisture eliminator section. Water droplets in the airstream are removed and drain back to the wash liquid reservoir tank. chemical The clean, processes dry air is then recirculated to the work area or discharged through air exhaust ducts.

The tangential scrubbers whirling flow pattern of both air and liquid ascends the multiple venturi sections for with dynamic impingement creating high collection efficiency. The wash chemical liquid is driven to the outside of the top moisture eliminator section of the scrubber by centrifugal processes force, then drains back to the bottom reservoir. Entrained dirt particles settle to the air and scrubbers bottom of the reservoir. Clean wash liquid for is drawn from the surface of the reservoir and ecirculated in a closed system, thus reducing water consumption. The Monroe Multiple Venturi Air Scrubber contains no moving parts. The entry area and the venturi throats are self-cleaning. The maintenance requirements for this chemical unit are low. It is not necessary to enter the structure for cleaning, as is required with many other air scrubbers. There is no packing required, water distributors to clean, nozzles to maintain, or mechanical devices to cause downtime. Once placed on line, the Monroe Multiple Venturi Air Scrubber operates continuously with sustained efficiency. Normally, the high efficiency of a single stage Monroe Multiple Venturi Air Scrubber will handle most industrial processes.For difficult processes applications two or three stage systems are available. High removal efficiency can be achieved on chemical fumes because of excellent liquid/gas contact and long residence time. The self induced water recirculating system provides a convenient means of adding neutralizing air chemicals.

Recirculate Clean Air In many installations, such scrubbers as buffing and polishing, metal finishing and grinding foundry operations etc., it is possible to recirculate clean, contaminant-free air back to the work area. This reduces the cost of plant ventilation systems and climate control needs. Proven High Efficiency Monroe Dual Throat Air Scubbers are currently operating continuously at high efficiency in many types of industrial installations throughout the for United States, Mexico and Canada. Cartridge cleaningis accomplished by reverse chemical compressed air pulses through a few cartridges at a time, allowing continuous processes operation without shut-down. These reverse pulses, with a velocity of twice the speed of sound, break away caked dust from the cartridge so that it can drop the collector bottom. Because of slower internal velocities through the collector, media replacement and maintenance labor costs are reduced. Collected oil mist and solids are continuously drained from the media without shut-down, significantly prolonging filter life and lowering overall operating costs. The Monroe Fiber Bed Mist Collector removesparticles as fine as 0.3 micron. While normal filters permit these particles to re-entrain into the outgoing clean air, Monroe''s self-draining filter is designed to prevent oil re-entrainment and recirculate clean air to the atmosphere.
