Description

本発明は、大気放出ガス中に含まれるガス状炭化水素の処理回収装置及び方法に係り、特に、ガソリン給油時に漏れ出すガソリン蒸気を処理するための装置に適した注油状態検出器に関する。   The present invention relates to an apparatus and a method for treating and recovering gaseous hydrocarbons contained in an atmospheric emission gas, and more particularly, to an lubrication state detector suitable for an apparatus for treating gasoline vapor leaking during gasoline refueling.

そこで本出願人は、特許文献1に記載したようなベーパを液化して再利用するベーパ回収技術を提案した。
しかし、荷卸開始時や終了時に回収装置を起動、停止させるスイッチの操作が必要であったり、また注油ホースから滴垂する可能性のある状態での注油口から注油ホースを取り外す恐れがあるなどの不都合を抱えていた。
Therefore, the present applicant has proposed a vapor recovery technique for liquefying and reusing vapor as described in Patent Document 1.
However, it may be necessary to operate the switch to start and stop the collection device at the start or end of unloading, or there is a risk that the lubrication hose may be removed from the lubrication port when dripping from the lubrication hose may occur. I had an inconvenience.

In the figure, reference numeral 14 denotes a return hose connecting the branch pipe 4c of the vent pipe 4 and the lorry 3, and an arrow → indicates the flow of fluid.

給油管2は、図2に示すように注油口20とタンクに連通する本管である注油配管21との間に中継管22を配置して構成され、この中継管22に注油状態検出器23が取り付けられている。注油状態検出器23を備えた中継管22は注油状態検出ユニット24としても取り扱うことが可能である。   As shown in FIG. 2, the oil supply pipe 2 is configured by arranging a relay pipe 22 between an oil supply port 20 and an oil supply pipe 21 which is a main pipe communicating with a tank. Is attached. The relay pipe 22 provided with the lubrication state detector 23 can also be handled as the lubrication state detection unit 24.

3 and 4 show an embodiment of the lubrication state detector in the form of an lubrication state detection unit. The relay pipe 22 constituting the lubrication state detection unit 24 includes an lubrication state detector 23.
An inflow port 27 and an outflow port 28 having a smaller diameter are provided at a position facing the case 26 constituting the float chamber 25 so as to have a vertical relationship.

流入口27には注油口20から流れ込んだ液を上部から受けてフロート室25に導く液受け29が設けられ、またフロート室25には液位に応動してスイッチからなるを作動させるフロート31が収容されている。   The inlet 27 is provided with a liquid receiver 29 that receives the liquid flowing from the oil filler port 20 from above and guides it to the float chamber 25. The float chamber 25 has a float 31 that operates according to the liquid level and is composed of a switch. Contained.

このように構成された装置の動作を図5のフローチャトに基づいて説明する。
この実施例において、ローリ3と地下タンク1の給油口2とをホース15で接続して荷卸を開始すると、給油口2の下部に配置された注油状態検出器23に燃料油が流れ込む。もとより流出口28からの流出量よりも流れ込量が多いからフロート室25のフロート31が上昇してフロートセンサ30がオンとなり(ステップ イ)信号が制御手段17に出力する。
The operation of the apparatus configured as described above will be described based on the flowchart of FIG.
In this embodiment, when unloading is started by connecting the lorry 3 and the fuel filler 2 of the underground tank 1 with the hose 15, the fuel oil flows into the lubrication state detector 23 arranged below the fuel filler 2. Of course, since the flow-in amount is larger than the flow-out amount from the outflow port 28, the float 31 in the float chamber 25 rises, the float sensor 30 is turned on (step A), and a signal is output to the control means 17.

制御手段17は、コンプレッサを作動させるとともに電磁弁7を開として通気管の蒸気を凝縮装置9に圧送する(ステップ ロ)。これにより、操作員に特別な作業を必要とすることなく、荷卸時の蒸気を凝縮装置9に確実に送気してベーパを回収することができる。   The control means 17 operates the compressor and opens the solenoid valve 7 to pressure-feed the vapor in the vent pipe to the condenser 9 (Step B). Thereby, the vapor | steam at the time of unloading can be reliably sent to the condensation apparatus 9, and a vapor | steam can be collect | recovered, without requiring a special operation | work for an operator.

このようにして地下タンク1への注油が継続している状態では注油状態検出器23の流出口28からの流出量よりも大量の液が流入するから、注油状態検出器23は信号を継続して出力しベーパを凝縮装置9で確実に回収する。   In this way, in a state where the oil supply to the underground tank 1 is continued, since a larger amount of liquid flows than the outflow amount from the outlet 28 of the oil supply state detector 23, the oil supply state detector 23 continues the signal. The vapor is reliably collected by the condenser 9.

地下タンク1への注油が終了すると、注油状態検出器23への液の流れ込みは停止するが、注油状態検出器23のフロート室25には液が残留していてかつ流出口28からは徐々に排出されるから所定時間が経過した段階、つまり給油ホースの液垂れが終了した時点でフロート31が所定位置まで降下してフロートセンサ30がオフとなり(ステップ ハ)信号が停止する。   When the lubrication to the underground tank 1 is finished, the flow of the liquid to the lubrication state detector 23 stops, but the liquid remains in the float chamber 25 of the lubrication state detector 23 and gradually from the outlet 28. When a predetermined time has elapsed since the discharge, that is, when the oil hose has finished dripping, the float 31 is lowered to a predetermined position, the float sensor 30 is turned off (step C), and the signal is stopped.

制御手段17は、コンプレッサを停止させるとともに電磁弁7を閉とし、さらに報知器を18作動させて注油が完了したことを操作員に知らせる(ステップ ニ)。   The control means 17 stops the compressor and closes the solenoid valve 7, and further operates the alarm 18 to notify the operator that the lubrication has been completed (step D).

このようにローリからの注油が完了してさらに所定時間が経過した時点で給油の完了を報知するため、ホースから滴垂する可能性のある状態での給油口2からの取り外しを防止でき、また凝縮装置の無用な運転を防止できる。   In this way, since the completion of the refueling is notified when a predetermined time has elapsed after the completion of the lubrication from the lorry, it is possible to prevent the fuel from being removed from the refueling port 2 in a state where it may be dripped from the hose. Unnecessary operation of the condenser can be prevented.

なお、上述の実施例においては、注油状態検出器23を中継管を介して給油管に配置しているが、給油管に直接取り付けても同様の作用効果を奏する。   In addition, in the above-mentioned Example, although the lubrication state detector 23 is arrange | positioned in the oil supply pipe via the relay pipe, there exists the same effect even if it attaches directly to an oil supply pipe.
