Petroleum separation device based on density separation method and separation method thereof

Abstract

The invention discloses a petroleum separation device based on a density separation method and a separation method of the petroleum separation device, and belongs to the technical field of petroleum exploitation. The petroleum separation device comprises a centrifugal barrel, the top of the centrifugal barrel is sleeved with a petroleum conveying pipe, and the bottom of the centrifugal barrel is sleeved with a rotating disc; a motor is arranged on the bottom surface of the centrifugal barrel, the motor is connected with the rotating disc, and a plurality of blades are arranged on the top surface of the rotating disc; a transmission mechanism is arranged between the top surfaces of the blades and the centrifugal barrel, the transmission mechanism is connected with a flushing mechanism, an oil collecting mechanism is arranged at the bottom of the centrifugal barrel, a bottom plate of the centrifugal barrel is sleeved with one end of a slag discharging pipe, the other end of the slag discharging pipe is sleeved with the top of one side of a water collecting tank, a filter plate is arranged in the water collecting tank, and a water discharging pipe is fixedly sleeved with the bottom of the water collecting tank. Petroleum enters the centrifugal barrel after being extracted, gas discharge and layering speed are accelerated through rotary centrifugation of the rotating disc, then an oil layer flows out through the oil collecting mechanism, a sediment layer and a water layer are discharged through the slag discharging pipe, the discharged water layer repeatedly flushes the centrifugal barrel through the transmission mechanism and the flushing mechanism, and self-cleaning is achieved.

Description

technical field [0001] The invention relates to the technical field of oil exploitation, in particular to an oil separation device based on a density separation method and a separation method thereof. Background technique [0002] Oil extraction usually uses drilling methods to extract crude oil from the ground. The extracted oil is usually a mixture of oil, gas, water and sediment, so it needs to be separated to separate the oil from other impurities. The current separation method uses Density separation method, that is, through the different densities of oil, water and sediment, the oil is allowed to stand and stratify, and the gas overflows automatically, while the sediment is located in the bottom layer of the liquid, the water is in the middle layer, and the oil is in the top layer, and then the top layer is extracted However, the separation speed of the current separation device is slow, and it is easy to absorb the water layer in the middle when extracting the oil lay...

[0002] Oil extraction usually uses drilling methods to extract crude oil from the ground. The extracted oil is usually a mixture of oil, gas, water and sediment, so it needs to be separated to separate the oil from other impurities. The current separation method uses Density separation method, that is, through the different densities of oil, water and sediment, the oil is allowed to stand and stratify, and the gas overflows automatically, while the sediment is located in the bottom layer of the liquid, the water is in the middle layer, and the oil is in the top layer, and then the top layer is extracted However, the separation speed of the current separation device is slow, and it is easy to absorb the water layer in the middle when extracting the oil layer, and it is difficult to clean the bottom sediment layer, which affects the subsequent separation process. Therefore, we propose a Oil separation device and separation method based on density separation method are used to solve the above problems
