Method for emptying three-head deconcentrator and oil-water separation barrel

Abstract

The invention discloses a method for emptying a three-head deconcentrator and an oil-water separation barrel. The oil-water separation barrel is placed above the oil discharging mouth of an oil tank,the oil discharging mouth of the oil-water separation barrel is connected with the three-head deconcentrator through an oil-resistant pipeline, and a lower water drainage mouth of the oil-water separation barrel is connected with a three-stage oil separating tank through an oil-resistant pipeline so as to achieve separation of oil and water; the three-head deconcentrator is installed on the oil discharging mouth, an oil inlet in a filter is connected with a homemade joint of an oiling machine through an oil-resistant pipeline, and an oil outlet and the three-head deconcentrator are installed on the filter for rust removal; the three-head deconcentrator is installed on the oil discharging mouth, and oil is introduced into the oil discharging mouth of the oil tank through a separator so as to dilute a protective agent. According to the method for emptying the three-head deconcentrator and the oil-water separation barrel, emptying and returning to the tank of one same oil product in the three pipelines can be achieved simultaneously by achieving separation of the oil and water through the oil-water separation barrel, so that the work efficiency is improved, the emission loss is reduced, and pollution to the environment is reduced; in addition, preservative, lubricant and other substances in the new oiling machine and a hose can be mixed with the oil product in the oil tank in a closed cycle mode for dilution, and therefore the method is safe and environmentally friendly.

Description

technical field [0001] The invention belongs to the field of oil and gas, and in particular relates to a method for emptying a three-head splitter and an oil-water separation barrel. Background technique [0002] With the in-depth development of the transformation and development strategy of the enterprise, there are more and more various transformation projects in gas stations, among which the transformation of oil tanks, the replacement of fuel dispensers or refueling gun hoses are relatively common projects. However, the renovation of the oil tank needs to be filled with water first, and then remove the water impurities. After replacing the fuel dispenser and the hose, the protective agent inside must be diluted and the rust in the oil pipe should be removed. Otherwise, the water, protective agent, rust and other impurities The remaining oil will not only damage the flow meter of the fuel dispenser, but also seriously affect the quality of the oil. Usually, at least 2 oi...

However, the renovation of the oil tank needs to be filled with water first, and then remove the water impurities. After replacing the fuel dispenser and the hose, the protective agent inside must be diluted and the rust in the oil pipe should be removed. Otherwise, the water, protective agent, rust and other impurities The remaining oil will not only damage the flow meter of the fuel dispenser, but also seriously affect the quality of the oil

Usually, at least 2 oil tank trucks are required to be on site for the removal of miscellaneous water, but when the schedule of oil tank trucks is tight, the emptying work has to be postponed

However, the emptying operation of diluting the protective agent and removing rust can only connect one pipeline at a time, and each pipeline must discharge at least thousands of liters of oil to make the oil of the dispenser meet the standard, which takes a long time, and the oil and gas pollution on site is very serious, high The concentration of oil and gas increases the risk of flammability and explosion on site, posing a greater threat to the safety of gas stations
