Online oil-gas recovery intelligent control system

Abstract

The invention discloses an online oil-gas recovery intelligent control system. The system comprises a gas flow meter and a monitoring host. The gas flow meter is connected to a return gas pipeline of an oil-gas recovery refueling gun in series. A liquid flow meter is connected to an oil circuit of a refueling machine in series. A sensor is arranged in the gas flow meter. An encoder is arranged on the liquid flow meter. The sensor transmits detected data to a control mainboard through a data line. The encoder transmits the detected data to the control mainboard through a data line. The control mainboard processes the received data and then controls the magnitude of flow of an oil-gas recovery pump or the magnitude of gas flow of an oil-gas recovery solenoid valve. The control mainboard transmits the processed data and the received data to the monitoring host for storage at the same time. The monitoring host transmits the gained stored information to a remote master control host. By adopting the online oil-gas recovery intelligent control system, real-time monitoring and intelligent adjustment of oil-gas recovery of a gas station are achieved, the oil-gas recovery gas-liquid ratio can be made to meet the atmospheric emission requirements all the time, air pollution is relieved, and on-line monitoring is achieved.

Description

Technical field: [0001] The invention relates to the technical field of oil and gas recovery, and more specifically relates to an online intelligent control system for oil and gas recovery. Background technique: [0002] With the continuous improvement of my country's economic development level, environmental protection issues have attracted more and more attention from the government and ordinary people. In order to reduce and control the pollution of the atmospheric environment caused by oil and gas emitted by gas stations, the State Environmental Protection Administration issued and implemented GB20952-2007 "Emission Standards of Air Pollutants for Gas Stations" in 2007, requiring gas stations in all regions to carry out secondary oil and gas recovery transformation before 2015. Moreover, gas stations with an annual gasoline sales volume of more than 8,000 tons and gas stations with an annual gasoline sales volume of more than 5,000 tons in cities with excessive ozone con...

Problems solved by technology

[0004] Due to the instability of the gas, with the change of time and environment, the existing oil and gas recovery device cannot meet the requirements, and manual detection and adjustment are required from time to time. The cost is high and often cannot meet the standard.

The current online monitoring system for secondary oil and gas recovery only achieves online detection of oil and gas recovery, which can only serve as an early warning and cannot fundamentally solve this problem
