Description

加油站地下油管零污染警示設備 Gas station underground tubing zero pollution warning equipment

本設備是有關於一種加油站地下油管零污染警示設備，特別是指一種埋設於加油站地下油管之路徑下方，可避免及預防加油站設於地面下的地下油管洩漏之警示設備。This equipment is related to a zero-pollution warning device for underground oil pipes of gas stations, especially a warning device buried under the path of underground oil pipes of gas stations to avoid and prevent underground oil pipes leaking from gas stations.

一般加油站其儲油槽及管線皆埋設於地下，因此儲油槽或地下油管易受氧化腐蝕、外力破壞或其他原因造成洩漏，因而污染周遭的土壤及地下水。根據研究，埋設10年以上的儲油槽及管線有46%會發生洩漏，而埋設15年以上者，其洩漏機率更高達71%。Generally, the oil storage tanks and pipelines of the gas station are buried in the ground. Therefore, the oil storage tank or underground oil pipeline is vulnerable to oxidative corrosion, external force damage or other causes, thus polluting the surrounding soil and groundwater. According to the study, 46% of the oil storage tanks and pipelines that have been buried for more than 10 years will leak, and those who have been buried for more than 15 years have a leakage rate of 71%.

在典型的加油站中，燃油係儲存於油槽中，配合設於地下連接之地下油管，將油槽中之燃油傳遞至各加油島下方，再配合分配器連接加油島上之配送泵，方便使用者驅動配送泵汲取燃油；然而，地下油管會因施工不良或長期使用後之脆裂而洩漏，在好發地震的臺灣更容易因震動而產生破裂致使油品洩漏之情形產生。In a typical gas station, the fuel system is stored in the oil tank, and is connected to the underground oil pipe connected to the underground, and the fuel in the oil tank is transferred to the bottom of each fueling island, and then the distributor is connected with the distribution pump on the oil island to facilitate the user to drive. The distribution pump draws fuel; however, underground oil pipes may leak due to poor construction or brittle fracture after long-term use. In Taiwan, where earthquakes occur, it is more likely to cause oil leakage due to vibration.

為偵測加油站中之儲油槽或地下油管內之油品洩漏，有如專利第432181號「操作中地表上儲槽偵漏系統及方法」，係在地下儲槽外圍及地下管線附近選定最佳的位置，打數個注氣井/抽氣井；接著在地下儲槽及管線中加入一種或數種不同之揮發性化學示蹤劑，同時在地下儲槽及管線附近填土部分之注氣井/抽氣井用氮氣或其他氣體沖排填土部分之土壤氣體；在抽氣井觀察土壤氣體中揮發性示蹤劑之出現及濃度之變化，當抽氣井土壤氣體中揮發性示蹤劑之出現與否可以判識地下儲槽及管線洩漏與否。再如中華民國第502117號專利之「土壤氣體採樣方法」與美國專利US5,235,863之「Soil-Gas Sampling Apparatus」觀之，其係採用負壓真空進行土壤氣體取樣；再由中華民國第I294093號專之利「並聯式土壤氣體採樣方法」觀之，其係以並聯取代串聯方式獲得較大之土壤氣體量；且再以美國專利US6,598,458之「Automated soil gas monitoring chamber」觀之，其係以多氣室進行多點重複性採樣，另再由美國專利US7,659,123之「In Situ remedial Alternative and Aquifer Properties Evaluation Probe System」其係進行土壤氣體回收。In order to detect oil spills in oil storage tanks or underground oil pipes in gas stations, such as Patent No. 432181 "Stop tank storage detection system and method in operation", the best choice is made in the vicinity of underground storage tanks and underground pipelines. Position, hit several gas injection wells/exhaust wells; then add one or several different volatile chemical tracers to the underground storage tanks and pipelines, and simultaneously fill the gas injection wells in the underground storage tanks and near the pipelines. The gas well flushes the soil gas of the filling part with nitrogen or other gas; observes the occurrence and concentration change of the volatile tracer in the soil gas in the pumping well, and the presence or absence of the volatile tracer in the soil gas of the pumping well can be Identify the underground storage tanks and pipelines leaking or not. For example, the "Soil Gas Sampling Apparatus" of the Republic of China No. 502117 and the "Soil-Gas Sampling Apparatus" of the US Patent No. 5,235,863, which use a vacuum vacuum for soil gas sampling; and then by the Republic of China No. I294093 The "Parallel Soil Gas Sampling Method" is used to obtain a larger amount of soil gas in parallel and in series; and the "Automated soil gas monitoring chamber" of US Patent No. 6,598,458 is used. Multi-point repetitive sampling is performed in multiple chambers, and soil gas recovery is performed by the "In Situ remedial Alternative and Aquifer Properties Evaluation Probe System" of U.S. Patent No. 7,659,123.

然而前述之各項專利而言，皆係當儲油槽或地下油管內之油品已洩漏於土壤中，再經由各項土壤監控或檢測方式來達到預警及監控的目的；此時，油品早已係漏並汙染附近土壤，雖可避免汙染擴大，但仍須對已汙染區域進行整治，對加油站業者來說仍是一大負擔。However, all of the above patents are when the oil in the oil storage tank or the underground oil pipe has leaked into the soil, and then through various soil monitoring or detection methods to achieve the purpose of early warning and monitoring; at this time, the oil has already been used. Leakage and pollution of nearby soils, although to avoid the expansion of pollution, but still need to rectify the contaminated areas, is still a big burden for gas station operators.
