Background technique
Inventor's Miao TongChun of this patent is once in the ancestral petroleum Department of Industry, oil field, Jiangsu, Nanjing Refinery work 7 years, and peaceful oil transport pipeline was investigated heating station and oil transport pipeline to the Shandong.Comrade Deng was once pointed out: " oil field, Jiangsu produces one ton of crude oil, is equivalent to Xinjiang Oilfield and produces seven tons of crude oil." this be because the oil field, Jiangsu near Shanghai, developed area, southern Jiangsu; these developed areas consume petroleum many, transport the oil refinery of oil to Shanghai and Nanjing from Xinjiang Oilfield, and transportation range is long; big with the long-distance energy consumption of transporting oil of oil truck, the cost of transportation height.
The temperature of the crude oil that in oil transport pipeline, circulates is 50~58 ℃; Greater than the ambient temperature around the oil transport pipeline; Especially at the night of northern area and southern area, the low temperature in the oil transport pipeline surrounding environment can reduce the wall temperature of oil transport pipeline tube wall, and then is reduced in the crude oil temperature that circulates in the pipeline.When the crude oil temperature in the oil transport pipeline was lower than 50 ℃, the flow velocity of crude oil can reduce gradually, even stopped to flow.The oil worker is had many seats heating station separated by a distance in the centre of very long petroleum pipeline, heat with the outer wall of Electric heating appliance to oil transport pipeline, increases the crude oil temperature in the pipeline through improving wall temperature.Crude oil through heating circulates forward, owing to receive the influence that is lower than 50 ℃ ambient temperature around the oil transport pipeline, crude oil is cooling gradually in the process of circulation, during to next heating station, need heat the increase crude oil temperature again, could continue mobile forward.Experiment is found: the temperature and the crude oil temperature of oil transportation tube wall are more or less the same, and the wax that contains in the oil just is not easy on the transport pipe inwall, to generate the wax deposit layer.If the wax deposit bed thickness on the transport pipe inwall, the flow velocity of crude oil in oil transport pipeline will slow down.
Over nearly 5 years, China has become the big country that makes solar cell, and a large amount of solar cells also needs vast domestic demand except outlet, the supply Domestic market.The energy that is radiated at the sunlight on the oil transport pipeline never obtains good use, never is used to promote crude oil circulation freely in oil transport pipeline.
In the heating station midway of oil transport pipeline, all adopt Electric heating appliance that the tube wall of oil transport pipeline is heated, the electric energy that Electric heating appliance wherein all relies in the power supply network is used as the energy, and the coal electricity occupies the share of total electric weight 81% in the power supply network.Can give off a large amount of carbon dioxide and sulfur dioxide in the process of coal fired power generation, use a large amount of coal electricity supply Electric heating appliances that oil transport pipeline is heated, meeting weighting ring environment pollution is unfavorable for energy-saving and emission-reduction.
