PROCESS AND APPARATUS FOR TREATMENT OF VOLATILE ORGANIC COMPOUNDS

摘要

A process and apparatus for treatment of volatile organic compounds and the process comprises an untreated airflow dew point temperature sensing step of sensing a dew point temperature of the untreated airflow as a reference temperature, a humidification and condensation processing step of spraying water mist all over the exhaust gas flow and condensing the exhaust gas flow into condensate contained the volatile organic compounds, a treated exhaust gas flow dew point temperature sensing step of sensing a dew point temperature of the treated exhaust gas flow after the humidification and condensation processing step, a collection step of collecting dropped condensate from the humidification and condensation processing step and then transporting the dropped condensate back to the humidification and condensation processing step for circulation spray, and a control step of controlling the dew point temperature of the treated exhaust gas flow to be close to the reference temperature.

1. A process for treating volatile organic compounds (VOC's) contained in exhaust gas flow, comprising:
a) an untreated airflow dew point temperature sensing step of sensing a dew point temperature of the untreated airflow as a reference temperature; b) a humidification and condensation processing step of spraying water mist all over the exhaust gas flow to increase humidity thereof and condensing the exhaust gas flow into condensate contained the volatile organic compounds; c) a treated exhaust gas flow dew point temperature sensing step of sensing a dew point temperature of the treated exhaust gas flow after the humidification and condensation processing step; d) a collection step of collecting dropped condensate from the humidification and condensation processing step and then transporting the dropped condensate back to the humidification and condensation processing step for circulation spray; and f) a control step of controlling the dew point temperature of the treated exhaust gas flow to be close to the reference temperature.
