Description

Technical Field

[0001] The utility model belongs to the technical field of mixing valves, in particular to a double-seat electric dehydration and desalination mixing valve. Background Art

[0002] In petrochemical industry, crude oil electric desalting is one of the most important processes. Before the crude oil enters the electric desalting tank, it needs to be injected with a certain proportion of washing water. Then, through mixing, the oil and water are dispersed and the contact area is increased. The salt in the crude oil is dissolved into the water phase. Then, under the action of the high-voltage electric field in the electric desalting tank, the oil and water are separated. The salt in the crude oil will be removed together with the water. The mixing of crude oil and water is achieved through a static mixer. At present, as the oil production stage enters the later stage, the properties of crude oil are becoming more and more complex. For crude oil with high specific gravity, high viscosity and high salt content, the static mixer is used to separate the oil and water. Traditional mixing valves can no longer achieve the mixing effect required for sufficient desalination. Because their internal shape is a hemisphere, the mixing of crude oil and water is achieved by adjusting the valve opening, that is, by changing the angle of the hemisphere within the valve body to change the crude oil flow area, thereby changing the crude oil flow rate. In this case, when the crude oil processing volume is small, even if the mixing valve is fully closed, the ideal flow rate cannot be achieved, resulting in insufficient mixing of the crude oil and water when flowing through the mixing valve, and the inability to form a uniform oil-water emulsion. The salt content in the crude oil treated by the electrical desalting process exceeds the standard. Utility Model Content
