1、氣體流量計：每兩個加油點安裝一個，用于監(jiān)測給車輛加油時的油氣回收量

　　1. Gas flow meter: installed at every two refueling points to monitor the amount of oil and gas recovered when refueling the vehicle

　　2、氣體壓力傳感器：用于持續(xù)測量油氣空間的壓力，以監(jiān)測儲油罐泄漏和過壓

　　2. Gas pressure sensor: used to continuously measure the pressure in the oil and gas space to monitor oil tank leaks and overpressure

　　3、isd軟件增強模塊：每個液位儀安裝一個，用于激活isd軟件和模塊

　　3. ISD software enhancement module: Install one for each level gauge to activate ISD software and modules

　　4、nvmem2board內(nèi)存：每個tls控制臺安裝一個，為isd存儲報告，并提供可拓展的內(nèi)存空間

　　4. Nvmem2board memory: Install one for each TLS console to store ISD reports and provide expandable memory space

　　5、isd系統(tǒng)基于tls-3050r智能型液位儀管理平臺。由于采用了化設計，tls-3050r液位儀同時支持動態(tài)測漏，可選配多種監(jiān)測傳感器，為每一種油品自動建立油罐與油槍的映射關系isd系統(tǒng)在加油機內(nèi)的油氣回收管路上串聯(lián)測量油氣流量的流量計，測量所回收油氣的體積流量，將這一體積流量與此次加油的油品液體流量進行比較，即可測得油氣回收過程中的氣液比同時，通過油氣壓力測量已聯(lián)通的油氣回收管道和地下油罐的壓力值，通過此壓力值的波動及其變化速度，監(jiān)測整個加油站系統(tǒng)的密閉性和油氣泄漏情況。

　　5. The ISD system is based on the TLS-3050R intelligent liquid level instrument management platform. Due to the adoption of chemical design, the tls-3050r level gauge supports dynamic leak detection and can be equipped with multiple monitoring sensors to automatically establish a mapping relationship between the oil tank and the oil gun for each type of oil. The ISD system is connected in series with a flow meter on the oil and gas recovery pipeline inside the refueling machine to measure the volume flow rate of the recovered oil and gas. By comparing this volume flow rate with the liquid flow rate of the oil being refueled, the gas-liquid ratio during the oil and gas recovery process can be measured. At the same time, the pressure values of the connected oil and gas recovery pipeline and underground oil tank can be measured through oil and gas pressure measurement. By measuring the fluctuation and change speed of this pressure value, the airtightness and oil and gas leakage of the entire gas station system can be monitored.

　　6、油氣和油氣壓力傳感器所采集到的數(shù)據(jù)，統(tǒng)一上傳至tls控制臺進行統(tǒng)計分析。在油氣回收系統(tǒng)工作處于非正常狀態(tài)時，在線監(jiān)測系統(tǒng)會發(fā)出輕度或重度警告。若警告的問題在一段時間內(nèi)尚未得到解決，在線監(jiān)測系統(tǒng)不但再次發(fā)出警報，而且會采取相應措施停止加油。

　　6. The data collected by oil and gas and oil and gas pressure sensors are uploaded to the TLS console for statistical analysis. When the oil and gas recovery system is operating in an abnormal state, the online monitoring system will issue a mild or severe warning. If the warning issue has not been resolved within a period of time, the online monitoring system will not only issue another alarm, but also take corresponding measures to stop refueling.

　　油氣回收設備的回收效果檢測

　　Detection of recovery effect of oil and gas recovery equipment

　　1、油氣回收檢測設備，油氣回收檢測設備分為便攜式和固定式，便攜式可以隨身攜帶把儀器放到排放口放置5分鐘就可以分析出排放的油氣濃度，然后根據(jù)數(shù)值判定油氣排放達標還不達標，由于便攜式油氣回收檢測設備的方便性所以售價比較昂貴，一般也只有環(huán)保監(jiān)測部門配備，對于油氣揮發(fā)企業(yè)來講他們是不愿意配備的。

　　1. Oil and gas recovery detection equipment is divided into portable and fixed types. Portable equipment can be carried around and placed at the discharge outlet for 5 minutes to analyze the concentration of oil and gas emissions. Then, based on the value, it can be determined whether the oil and gas emissions meet the standard or not. Due to the convenience of portable oil and gas recovery detection equipment, the price is relatively expensive, and it is generally only equipped by environmental monitoring departments. For oil and gas volatilization enterprises, they are unwilling to equip it.

　　2、固定式油氣回收檢測設備一般針對油氣揮發(fā)排放量較大的企業(yè)進行的定點監(jiān)測，以避免在重大污染事故發(fā)生不能及時處理。固定式檢測設備一般是撬裝式設備，檢測探頭安放在油氣回收裝置集中排放口，24小時進行檢測，動力需要安防地點提供220V動力電。數(shù)據(jù)可以通過互聯(lián)網(wǎng)同步傳送到終端接收服務器24小時進行記錄檢測。相對于便攜式檢測設備，固定式檢測設備更準確，更經(jīng)濟，更耐用，實現(xiàn)的功能更全面。比如可以24小時檢測， 可以隨時數(shù)據(jù)傳送，可以無人值守檢測。固定式檢測設備需要安放人員定期的巡視，維護保養(yǎng)。這樣才能更好的調(diào)整油氣回收裝置運行參數(shù)讓油氣回收設備更加高效工作

　　2. Fixed oil and gas recovery detection equipment is generally used for fixed-point monitoring of enterprises with large oil and gas volatilization emissions, in order to avoid the inability to handle major pollution accidents in a timely manner. Fixed detection equipment is generally a pry mounted device, with the detection probe placed at the centralized discharge outlet of the oil and gas recovery device, and tested 24 hours a day. The power requires a 220V power supply from the security location. The data can be synchronously transmitted to the terminal receiving server via the Internet for 24-hour record detection. Compared to portable detection devices, fixed detection devices are more accurate, economical, durable, and achieve more comprehensive functions. For example, it can be detected 24 hours a day, data can be transmitted at any time, and unmanned detection is possible. Fixed detection equipment requires personnel to conduct regular inspections and maintenance. Only in this way can the operating parameters of the oil and gas recovery device be better adjusted to make the oil and gas recovery equipment work more efficiently
