Drying + Deep Cooling Recovery + Rotary Concentration

  • Drying + Deep Cooling Recovery + Rotary Concentration
  • Drying + Deep Cooling Recovery + Rotary Concentration
Principle introduction:

After pretreatment of filtering and cooling, the organic waste gas with high concentration enters the the drying tank to completely remove the moisture. We will obtain a water-free solvent after the dried exhaust gas condensed at a deep low-temperature(-60 to -10 °C can be selected according to the VOCs composition). The condensed exhaust gas still contains a certain concentration of VOCs components, then it will enter the rotor for adsorption and concentration. By now we will get purified gas which can be discharged by standard through the chimney. Finally the reactivation exhaust of rotor and drying tank will return to the inlet manifold process of device.

Product Features

▶  Suitable for medium or low air volume + high concentration of exhaust gas and other working conditions.

▶  The exhaust gas will be discharged by standard.

▶  High recovery benefits.

▶  Recovering solvent with water content 0.1% ~ 0.4%.

▶  Customized design according to working conditions, low energy consumption, 24h continuous and stable operation.

▶  Low maintenance cost and long life span.

▶  Our product can reduces the solvent content of highly concentrated exhaust gases to a safe range, ensuring the safe and stable operation.
