Abstract
In the present invention, a waste solution and a exhaust gas are guided together from a drain cup DC into a storing means through common discharge means. Naturally, the gas-liquid separation is performed within the storing means in place of performing the gas-liquid separation within the drain cup DC. Therefore, the waste solution is not solidified within the drain cup so as to plug the common discharge means. Also, a predetermined waste solution is kept stored in the storing means included in the coating apparatus of the present invention, making it possible to permit the surface of the stored waste solution to absorb the mist, and the waste solution is prevented from being solidified within the storing means. Further, since a minimum amount of the exhaust gas is kept discharged even during non-operation of the coating apparatus by using an exhaust gas damper whose degree of opening can be controlled, the waste solution stored in the storing means is prevented from being solidified. Also, the waste solution evaporated within the storing means can be released to the outside.
