Description

Technical Field

[0001] The present invention belongs to the technical field of electric dehydration and desalination experiments, and specifically relates to a multi-form and multi-configuration adjustable electric dehydration and desalination experimental device. Background Art

[0002] Crude oil is a very complex dispersion system. In addition to the components required for industrial production, crude oil also contains a large amount of impurities such as water and salts. These components will seriously affect the processing and production of crude oil, corrode equipment, increase energy consumption, and even block pipelines and cause shutdowns. Therefore, desalination and dehydration must be carried out before crude oil processing.

[0003] Most of the existing electric dehydration and electric desalination devices are in the form of storage tanks. Electrode plates are fully arranged horizontally inside the storage tanks, and crude oil is pumped into the storage tanks for electric dehydration and electric desalination.

[0004] However, the tank of the electric dehydration and desalination device is too large in size, and the vertical space occupied by the plates is also very large. In addition, the height of the plates placed inside the tank during the electric dehydration and desalination process will also affect the actual effect of the electric dehydration and desalination. Therefore, the position inside the tank is very important. In addition, whether it is the type of plates, the upper and lower heights of the plates, the type of electricity used to power the plates, and the type of demulsifier added, these variables will affect the actual electric dehydration and desalination effects of different types of crude oil.

[0005] Therefore, a set of experimental equipment that can easily replace the plates and adjust the position of the plates is needed to test crude oil from different origins, regions and contents to obtain the optimal layout effect of the electric dehydration and desalination device. Summary of the invention

[0006] In order to solve the above problems, this paper proposes a multi-form and multi-configuration adjustable electric dehydration and electric desalination experimental device. The experimental device is a horizontal experimental tank. The interior of the experimental tank is connected to the power control cabinet through a high-voltage electrical connection line. The oil inlet distribution pipeline of the experimental tank is connected to the crude oil pipeline. The demulsifier injection pipeline and the water injection pipeline are all connected to the crude oil pipeline. The crude oil pipeline, the demulsifier injection pipeline, and the water injection pipeline are all transported by pumps respectively. The experimental tank is a horizontal U-shaped tank body with a conductive end. One end of the tank body is a detachable head, and the other end of the tank body is a multi-form electric field regulation end, which can be connected to different power supply forms, including AC power supply, DC power supply, intelligent response power supply, high-frequency power supply, etc. The inner side of the detachable head is vertically provided with a multi-channel high-voltage power introduction connection end, the outer side of the multi-form electric field regulation end is surrounded by a flange ring, and the outer side of the flange ring is sealed and installed with a plug-in flange cover. The inner side of the plug-in flange cover is connected to the multi-channel high-voltage power introduction connection An electrode plate is fixedly inserted horizontally between the connecting ends, the plug-in flange cover comprises a flange cover body and a positioning mounting socket, the inner surface of the flange cover body is vertically provided with a plurality of positioning mounting sockets, the multi-channel high-voltage electricity introduction connection end comprises an electrode conductive plate and a conductive buckle, the inner surface of the electrode conductive plate is vertically provided with a plurality of conductive buckles, the conductive buckles and the positioning mounting seat are horizontally aligned with each other, one end of the electrode plate is fixedly connected to the positioning mounting seat, and the other end of the electrode plate is connected to the conductive buckle through a conductive socket, and through the multi-form electric field regulating end, it is possible to design and install electrode plates of different structural forms according to different experimental requirements, and it is possible to verify the desalination and dehydration effects under different electric field positions by adjusting the electrode plates in different positions in the experimental tank up and down, and add various types of demulsifiers, so as to test various variable experiments and select the best device for the electric field arrangement and power supply form in the electric dehydration and desalination tank.

[0007] The shape of the tank body is a horizontal single-conductivity cylindrical tank body, and a high-voltage electrical connection line is provided through the center of the detachable head surface of the tank body. The upper side of the tank body is connected to the storage tank through a pipeline, and the lower side of the tank body is respectively connected to the crude oil pipeline and the injection pipeline through pipelines. One end of the high-voltage electrical connection line is connected to the multi-channel high-voltage electrical introduction connection end, and the other end of the high-voltage electrical connection line is connected to the power supply. By using the tank body of the experimental tank with one end conducting, the function of replacing the electrode plate from one end is realized, which is convenient for realizing the multi-functional and multi-variable experimental tank to carry out various experiments.

[0008] The power supply is a multi-form power supply, which includes an AC power supply, an AC / DC power supply, an intelligent power supply, and a high-frequency power supply.

The storage tank is a transparent static storage tank. The crude oil and injection liquid are poured into the interior of the experimental tank together through the two-in-one method, so that various crude oils and required demulsifiers or water can be poured in, allowing the experimental device to experiment with various types, thereby experimenting with various variables.

After the docking is completed, the electrode plate can be supported at both ends to ensure the stability of the electrode plate inside the tank body.

[0012] The electrode plate includes a horizontal electrode plate and a vertical electrode plate. One end surface of the electrode plate is conductively connected to the conductive buckle through a conductive groove, and the outer side of the other end surface of the electrode plate is fixedly assembled with the positioning mounting socket through bolts. Through two different forms of electrode plates, horizontal or vertical, different electrode plates can be replaced according to different forms, and one end of the electrode plate is fixedly connected to the positioning mounting socket, so as to be fixedly connected to the plug-in flange cover to ensure the installation stability and firmness of the electrode plate.

[0013] Beneficial effects:

[0014] Through the multi-form electric field regulating end, it is possible to design and install electrode plates of different structural forms according to different experimental needs, and it is possible to verify the desalination and dehydration effects under different electric field positions by adjusting the electrode plates up and down in different positions in the experimental tank, and add various types of demulsifiers, so as to test various variable experiments and select the best electric field layout and power supply form device in the electric dehydration and desalination tank.

[0015] By using a one-end conductive experimental tank, the function of replacing the electrode plate from one end is realized, which makes it easy to realize the multifunctional and multivariable experimental tank to carry out various experiments.

[0016] By using two different forms of AC and DC power supply control cabinets, different forms of electricity can be transmitted to the inside of the electric dehydration and electric desalination experimental device, thereby increasing the variables of the experiment and ensuring the accuracy of the experimental data.

[0017] By injecting crude oil and injection liquid into the test tank together in a two-in-one manner, various crude oils and required demulsifiers or water can be injected, allowing the experimental device to test various types and thus various variables.

[0018] By means of an electrode conducting plate arranged inside the tank body and a conducting buckle installed on the electrode conducting plate, the electrode plate can be fixedly installed inside the tank body, and power is transmitted to the motor plate through conduction of the electrode conducting plate, thereby achieving the electric dehydration and electric desalination effect of the electrode plate.

[0019] The flange cover can ensure that the open end of the tank body has sufficient sealing performance, and the electrode plate to be installed inside the experimental tank can be pre-installed and fixed to the flange cover by positioning and installing the socket inside the flange cover, thereby ensuring that the electrode plate can be stably and smoothly docked with the conductive buckle to ensure insulation performance, and after the docking is completed, the electrode plate can be supported at both ends to ensure the stability of the electrode plate inside the tank body.
