VACUUM-TYPE DRAINAGE COLLECTION SYSTEM AND DRAINAGE COLLECTION METHOD

PROBLEM TO BE SOLVED: To provide a vacuum-type drainage collection system and a drainage collection method for collecting drainage without leakage, in an economically efficient way.SOLUTION: A vacuum-type drainage collection system is provided that includes: a plurality of liquid storage tanks for storing drainage; a vacuum station having a collection tank into which drainage from the plurality of liquid storage tanks is collected, and a vacuum generator that introduces a negative pressure in the collection tank; a communication passage connecting each of the liquid storage tanks with the collection tank; a plurality of remote-controlled valves disposed in correspondence with each of the plurality of liquid storage tanks, for opening/closing the communication passage; measurement means disposed in correspondence with each of the plurality of liquid storage tanks, for measuring a condition of each of the plurality of liquid storage tanks; and control means for the remote-controlled valve that remote-controls an operation of the plurality of remote-controlled valves. The control means for the remote-controlled valve is capable of determining priority regarding an order of operation of the plurality of remote-controlled valves on the basis of an output signal from the measurement means, and remote-controlling the plurality of remote-controlled valves according to the priority.SELECTED DRAWING: Figure 1 【課題】漏洩なく液体を収集でき且つ経済的な真空式排液収集システム及び排液収集方法を提供する。【解決手段】排液が貯留される複数の液体貯留槽と、複数の液体貯留槽内の排液が収集される集水タンク及び集水タンクに負圧を導入する真空発生装置を備える真空ステーションと、複数の液体貯留槽の各々と集水タンクとを連通する連通路と、連通路を開閉するように、複数の液体貯留槽にそれぞれ対応して設けられる複数の遠隔操作弁と、複数の液体貯留槽の各々の状態を計測するように、複数の液体貯留槽にそれぞれ対応して設けられる計測手段と、複数の遠隔操作弁の動作を遠隔制御する遠隔操作弁制御手段と、を備える真空式排液収集システムが提供される。遠隔操作弁制御手段は、計測手段からの出力信号に基づいて、複数の遠隔操作弁の操作順について優先度を決定し、複数の遠隔操作弁を優先度に従って遠隔操作することができる。【選択図】図１
