Problems solved by technology
The existing three-phase separator has only one three-phase inlet, which requires a large space for gas-liquid separation, resulting in a large volume of the three-phase separator and high equipment investment; and the oil-water flows in a single direction in the tank, the residence time is short, and the oil-water separation effect is high. Poor, resulting in water in the oil, oil in the water, the quality of the separated oil does not meet the requirements, and the separated water does not meet the requirements of environmental protection indicators, and follow-up treatment is required to increase the operating cost of the device

Embodiment Construction
[0019] The present invention will be further described in detail below through specific embodiments in conjunction with the accompanying drawings.
[0020] Please refer to figure 1 , the present invention is a double-inlet three-phase separator, the difference is that it includes a sealed tank body 1, and the inner cavity of the tank body 1 is divided into an upper three-phase inlet area, a gas phase separation area, and a middle and lower part The liquid phase separation area, the bottom of the tank body 1 is provided with an oil phase outlet area and a water phase outlet area;
[0021] The three-phase inlet area is divided into two places, which are respectively located at the left and right ends of the upper part of the tank body 1. The two three-phase inlet areas are provided with three-phase inlet pipes 2, and the ends of the three-phase inlet pipes 2 are respectively provided with An inlet baffle 3 restricting the direction of material flow;
[0022] The gas phase sepa...

The invention relates to the technical field of separation and particularly relates to a double-inlet three-phase separator. The double-inlet three-phase separator is characterized in that an inner cavity of a tank body is divided into three-phase inlet regions, a gas-phase separation region and a liquid-phase separation region, and oil-phase outlet regions and a water-phase outlet region are arranged below the tank body; the three-phase inlet regions are located at the left and right ends of the upper part of the inner cavity of the tank body and are provided with three-phase inlet pipes and inlet baffles; the gas-phase separation region is located in the middle of the upper part of the inner cavity of the tank body and is provided with an air raising pipe and a gas-phase outlet; the liquid-phase separation region is located at middle and lower parts of the inner cavity of the tank body and is provided with a water-phase channel baffle and an oil collection groove, an oil collection groove baffle is arranged on the oil collection groove, and an oil guiding pipe is arranged at the bottom of the oil collection groove; the oil-phase outlet regions are located on the left and right sides below the tank body and are provided with oil collection tanks and oil-phase outlets; and the water-phase outlet region is located right below the tank body and is provided with a water dividing hopper and a water-phase outlet. The double-inlet three-phase separator has the beneficial effects that the contour size is small, the oil-water separation effect is good, the separated oil meets the quality requirement, separated water reaches environmental protection indexes, and separated gas does not contain liquid.
Description
technical field [0001] The invention relates to the technical field of separation, in particular to a double-entrance three-phase separator. Background technique [0002] In petrochemical plants, there are many occasions that require three-phase separation of oil, gas and water. The three phases of oil, gas and water have different physical and chemical properties, such as density and viscosity. , using the difference in properties between the three phases to separate oil, gas and water to a certain extent. The method of realizing the three-phase separation of oil, gas and water by gravity settling is widely used because of its simple principle and few internal parts of the equipment. The existing three-phase separator has only one three-phase inlet, which requires a large space for gas-liquid separation, resulting in a large volume of the three-phase separator and high equipment investment; and the oil-water flows in a single direction in the tank, the residence time is s...
