WHAT IS A ROTO-CONCENTRATOR PLANT?
The type rotor concentrator is a temperature swing adsorption device designed to remove continuously VOC from a low concentration air stream by adsorbing the VOC into a hydrophobic zeolite adsorbent and releasing the VOC into a small heated air stream for further treatment. The zeolite adsorbent is impregnated into a corrugated mineral fiber substrated formed into a rotor.
HOW DOES IT WORK?
• The rotor is mounted on a shalf and bearings and rotates slowly in the air system.
• As the rotor turns it passes through sealed sectors used for adsorption, desorption and cooling.
• Inlet process air is supplied to the system from ductwork. The process air containing a low concentration of VOC enters the inlet plenum and passes through a particular filter where excess dust and particulate is removed.
• From the outlet plenum the cleaned air is released into the atmosphere through ductwork.
• VOC is removed from the rotor by passing a small stream of hot air through the rotor in the opposite direction of the process air.
• The rotor cools this stream as VOC is desorbed and exits as concentrate at a temperature of about 50-60°C.
• Further treatment of the concentrate is usually inceneration provided.
• The process air leaving the rotor as it emerges from the cooling sector is heated by the rotor and can be used as desorption air by further heating. This “cooling air” is approximately 75-100°C. The use of this preheated air may be lower than the overall energy consumption of the system.
WHY TO CHOOSE OUR ROTO-CONCENTRATORS PLANTS?
• These plants, together with the smooth flow reversal through the rooms (without pressure fluctuations), allow maximum operational reliability in all conditions and requires no maintenance.
• They are equipped with an exclusive separation device, to the pression chamber, between the stream which had to be purified entering the plant and the one purified outgoing.
This device ensures the absence of leaks between the two flows.
