Description

ベント配管6の付着物の生成を抑制する方法の2つ目として、ベント配管洗浄液投入口9及びベント配管洗浄液排出口10を設けベント配管洗浄液を流すことも有効である。ベント配管6の内壁で凝縮した揮発物の凝縮液が、乾燥して熱硬化する前に、ベント配管洗浄液を流すことによって、付着物の生成を防止できる。ベント配管洗浄液は連続的に流しても断続的に流しても良く、断続的に流す場合でも流すタイミングは如何なるタイミングでも良いが、タンクがバッチ処理を行うタンクである場合は、バッチ処理が終了しタンク内の処理液2を次工程に移送した直後であることが好ましい。好ましくは30分以内、より好ましくは10分以内、更に好ましくは5分以内である。ベント配管洗浄液もベント配管冷却用冷媒と同じ理由で、処理液2の温度よりも低く、より好ましくは10℃以上低く設定することが良い。なお、図1は、ベント配管を冷却するジャケットと、ベント配管を洗浄するためのベント配管洗浄液投入口とベント配管洗浄液排出口10が設けられたタンクを示す。 As a second method of suppressing the formation of the deposit on the vent pipe 6, it is also effective to provide the vent pipe cleaning liquid inlet 9 and the vent pipe cleaning liquid outlet 10 and to flow the vent pipe cleaning liquid. By flowing the cleaning solution for the vent pipe before the condensate of the volatile matter condensed on the inner wall of the vent pipe 6 is dried and thermally cured, it is possible to prevent the generation of the deposit. The vent pipe cleaning liquid may be flowed continuously or intermittently, and may be flowed at any timing even if it is flowed intermittently, but if the tank is a tank for batch processing, batch processing is completed. It is preferable that the treatment liquid 2 in the tank be transferred immediately to the next step. Preferably it is within 30 minutes, more preferably within 10 minutes, still more preferably within 5 minutes. It is preferable to set the temperature of the treatment solution 2 lower than the temperature of the treatment liquid 2 and more preferably 10 ° C. or more lower than the temperature of the treatment liquid 2 for the same reason as that of the cooling fluid for cooling the vent pipe. Incidentally, FIG. 1, a jacket 8 for cooling the vent pipe 6 shows the tank vent pipe cleaning liquid inlet 9 and the vent pipe cleaning liquid discharge port 10 is provided for cleaning the vent pipe 6.
