Description

Technical Field

[0001] The utility model relates to the technical field of crude oil filtering equipment, in particular to crude oil filtering equipment for petroleum processing and production. Background Art

[0002] The main components of petroleum are carbon and hydrogen, accounting for 83-87% and 11-14% respectively; there are also small amounts of sulfur, oxygen, nitrogen and trace amounts of phosphorus, arsenic, potassium, sodium, calcium, magnesium, nickel, iron, vanadium and other elements. The specific gravity is 0.78-0.97, the molecular weight is 280-300, and the freezing point is -50-24°C. Crude oil can be refined and processed to obtain various fuel oils, solvent oils, lubricating oils, greases, paraffin, asphalt, liquefied gas, aromatics and other products, providing fuel, raw materials and chemical products for various sectors of the national economy. The current method of collecting crude oil is to use the elastic energy of the oil layer itself to spray the formation crude oil to the ground. The method is called self-flowing oil production. Self-flowing oil production mainly relies on the expansion of the gas dissolved in the crude oil as the pressure decreases. In the entire production process, the crude oil relies on the pressure energy provided by the oil layer to overcome gravity and flow resistance and flow on its own. No artificial energy is required. Therefore, self-flowing oil production is the simplest, most convenient and most economical oil production method.

[0003] After the current petroleum crude oil is collected, it is necessary to filter the petroleum crude oil to initially filter out impurities. The current initial filtering method for petroleum crude oil is filtering by a filter component. The crude oil after the initial filtration is then processed to obtain the required petroleum-derived fuel.

[0004] At present, the preliminary filtration of crude oil is carried out through a filter plate, which filters the impurities mixed in the crude oil. After the crude oil passes through the filter plate, the impurities mixed in the crude oil are filtered on the top of the filter plate. Due to the adhesion of crude oil, crude oil adheres to the gaps after the impurities accumulate. When the staff removes the impurities, the impurities adhere to the surface of the filter plate, which makes it inconvenient for the staff to completely remove the impurities. At the same time, the impurities adhere to the crude oil, which also reduces the filtering effect of the crude oil. Utility Model Content
