Abstract

The invention relates to a vertical oil filter, and belongs to the technical field of oil exploitation and separation. The filter comprises a vertical tank body, a fan stirring device, a solid grinding device and a bubbling air inlet device. The vertical tank body is provided with a liquid inlet, an exhaust port, an oil discharge port, a slag discharge port and an inclined filter screen. The inclined filter screen is located in the middle of the vertical tank body and divides the vertical tank body into a solid-liquid mixing area and a gas-liquid mixing area. The fan stirring device is provided with a baffle brush and is connected with the solid grinding device in a concentric circle mode. The inner pipe wall in the solid grinding device surrounds the spiral blade, and the outer pipe and the annular space are provided with fine filter screen openings. The bubbling air inlet device is located at the bottom of the vertical tank body, and filter cotton is arranged in each air hole. According to the vertical oil filter, solid and liquid can be separated, the quality of oil is improved, nitrogen is circularly filled into the oil in a condensation and high-temperature heating mode, light oil and heavy oil are separated according to different boiling points of the oil, production of oil products is better achieved, the viscosity of the oil is reduced, and flowing of the heavy oil is facilitated.

Description

technical field [0001] The invention belongs to the technical field of petroleum processing equipment, in particular to a vertical petroleum filter. Background technique [0002] In the process of oil exploitation, the extracted crude oil is generally a solid-liquid-gas three-phase mixed liquid, and contains impurities such as solid and water. The three-phase substances in the crude oil can be separated by the solid-liquid-gas three-phase separator, while the solid The liquid-gas three-phase separator is one of the most commonly used equipment in the oilfield development and production process. [0003] The solid-liquid-gas three-phase separator in the related art generally has a solid-liquid separation area, a gas-liquid separation area and an oil-water separation area. In the gas-liquid separation zone, the gas is separated from the liquid, and the gas is discharged through the exhaust port to realize gas-liquid separation. After that, the oil-water mixture after gas-liq...
