EMISSION GAS TREATMENT METHOD AND EMISSION GAS TREATMENT APPARATUS

摘要

An emission gas treatment apparatus recovers a recycle feed containing boron from emission gas discharged by a glass melting furnace. The apparatus includes a collection device for collecting a component containing boron from the emission gas by a wet process to obtain a collected liquid, a first filter for separating the collected liquid into a solid and a liquid, and an ion-exchange resin for forming a boron solution by removing an impurity from an extracted liquid obtained in the first filter. The apparatus also includes a mixing tank for mixing an extracted solid obtained in the first filter in the boron solution to form an extracted solid-containing solution, a second filter for separating the extracted solid-containing solution into a solid and a liquid, and a vacuum dryer for recovering the recycle feed from an extracted solid obtained in the second filter.
