Description

Technical Field

[0001] The present invention relates to the field of crude oil exploitation, and more specifically to a crude oil water content testing device. Background Art

[0002] It is customary to call unprocessed petroleum crude oil, a dark brown viscous oily liquid with green fluorescence and a special smell. It is a mixture of various liquid hydrocarbons such as alkanes, cycloalkanes, aromatic hydrocarbons and olefins. The main components 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℃. 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.

[0003] In the prior art, there is a graphene device for detecting the water content of crude oil, such as the Chinese patent number CN211122874U, which includes a measuring instrument body, a cover plate is rotatably installed on the measuring instrument body through a hinge, a mounting block is fixed to the side surface of the measuring instrument body, a rotating column is rotatably connected to the lower end of the inner side of the mounting block, a bottom plate is fixed to the upper surface of the rotating column, and a sliding groove is provided on the side surface of the bottom plate; by providing the mounting block, the rotating block, the rotating column, the bottom plate and the limit rod, it is convenient to increase the contact area between the measuring instrument body and the placement plane, avoid the measuring instrument body The small contact area with the placement plane makes it easy for the placement plane to slip when the measuring instrument body is working, and by providing the spring, the connecting block, the first permanent magnet, the second permanent magnet and the sealing plate, it is convenient to avoid the crude oil and water droplets directly contacting the cover plate, causing corrosion damage to the cover plate, and to improve the safety of the cover plate.

[0004] However, in the prior art, when crude oil is traditionally transported in a pipeline, it is necessary to test the water content of the crude oil before processing the crude oil. The amount of water content will affect the quality of the crude oil. The traditional method is to let the crude oil settle or push it at high pressure to separate or squeeze out the water from the inside of the crude oil. Although this type of method can separate and detect the water, due to the physical properties of the crude oil, a lot of water will still remain inside the crude oil. The detection accuracy of the above method is poor, and high-pressure squeezing of water will also increase the viscosity of the crude oil, which is not conducive to the flow of crude oil inside the pipeline.

Crude oil enters the interior of the wrapping cylinder, the interior of the heating chamber is filled, the electric heating tube is energized and heated, the moisture inside the crude oil is heated and evaporated, the temperature of the crude oil increases, the viscosity decreases, and it is easy to flow. Through the difference in boiling points, the moisture is vaporized and separated from the inside of the crude oil, and the vaporized water vapor enters the interior of the air intake cylinder.

The suction of the screw pump makes the crude oil flow to the right, and the crude oil is sucked to the left side of the sealing plate. As the shaft continues to rotate, the crude oil is squeezed into the inside of the oil outlet pipe. The equipment completes the entire crude oil suction process, solving the problem of the long cycle of traditional natural cooling of crude oil. BRIEF DESCRIPTION OF THE DRAWINGS
