GAS PURIFYING DEVICE

摘要

Reflow means (L 3 ) is provided in a gas purifying device, and the means causes liquid discharged from an element positioned on the downstream side of an airflow to reflow to a liquid circulation system path of an element positioned on the upstream side of the air flow. The liquid dissolves and removes low-concentration containment by gas-liquid contact, and this causes the liquid to lose the capability of dissolving and removing contaminant. The liquid is discharged from the element on the downstream side and is made to reflow to the element on the upstream side through reflow means, and contaminant is dissolved and removed by gas-liquid contact between the liquid and non-purified air containing high-concentration contaminant.
