Description

Technical Field

[0001] The utility model relates to the technical field of oil field development, in particular to a supporting structure of a multi-layer electrode plate. Background Art

[0002] The electrode structure of the crude oil electric dehydrator is varied. Through the design of the internal electrode structure and the arrangement of the electrodes, the distribution of the electric field in the tank can be reasonably designed. Therefore, the structure and arrangement of the electrodes are important factors affecting the dehydration effect of the electric dehydrator. At present, the most common electrode types are horizontal electrodes, vertical hanging electrodes, multi-layer squirrel cage electrodes, etc. The electrode plates are generally grid-shaped, among which horizontal electrodes are the most widely used.

[0003] Horizontal electrodes are generally provided with two or three layers of electrode plates in the electric dehydrator. Each layer of electrode plates is made of steel beams, and then a single electrode plate is assembled on it. These components are prefabricated in the factory and then assembled on site, which is very convenient. However, the electric field only exists between the plates in the horizontal electrode plate type electric dehydration equipment. The electric field area in the tank accounts for about 30% of the entire tank. The electric field occupancy rate is low, and the actual residence time of crude oil in the electric field area is short. Especially for the electric dehydrator with a two-layer electrode plate structure, when the oil-water interface fluctuates up and down, it is easy to affect the stability of the weak electric field, which is not conducive to the electric dehydration of raw materials.
