Zusammenfassung:To provide a water level detection system which is not restricted by use environment, and is maintenance-free.SOLUTION: A water level detection system 300 is provided for use in an exhaust gas treatment device, and comprises: a tank 20 in which circulation water circulating in the exhaust gas treatment device is housed; and a water supply and discharge mechanism which performs at least one of stopping of supply of new water to the exhaust gas treatment device and starting of discharge of circulation water from the exhaust gas treatment device when a water level in the tank reaches a first water level, and performs at least one of starting of supply of new water to the exhaust gas treatment device and stopping of discharge of circulation water from the exhaust gas treatment device when the water level in the tank reaches a second water level L2 lower than a first water level L1.SELECTED DRAWING: Figure 2 【課題】使用環境の制約を受けることがない、且つメンテナンスフリーの水位検知システムを提供する。【解決手段】排ガス処理装置内を循環する循環水を収容可能な槽20と、給排水機構であって、槽内の水位が第1の水位に達したときに、排ガス処理装置への新水の供給を停止すること、および、排ガス処理装置からの循環水の排出を開始することのうち少なくとも一方を行うように構成され、槽内の水位が第1の水位L1より低い第2の水位L2に達したときに、排ガス処理装置への新水の供給を開始すること、および、排ガス処理装置からの循環水の排出を停止することのうち少なくとも一方を行うように構成される給排水機構と、を備える排ガス処理装置に使用される水位検知システム300。【選択図】図2
