Emulsification treatment device of crude oil dewatering and sedimentation tank

Abstract

The invention relates to the technical field of intelligent manufacturing, and discloses an emulsification treatment device of a crude oil dewatering and sedimentation tank. The device comprises a tank body, sliding rails are fixedly installed on the inner wall of the tank body, the outer wall of each sliding rail is provided with a sliding groove, a sliding block is slidably connected to the inner wall of each sliding groove, a pad plate is fixedly connected to the side faces of the sliding blocks, a storage cylinder is fixedly connected to the top of the pad plate, positioning blocks are fixedly installed on the inner wall of the storage cylinder, and a rubber cylinder is clamped to the side faces of the positioning blocks. According to the emulsification treatment device, through the density difference design of the pad plate, the pad plate is always located on an emulsification layer; through the thermal expansion and contraction characteristics of an expansion liquid, the rubber cylinder can automatically open or close agent discharging pipes according to the emulsification degree of the emulsification layer, a demulsifying agent conveniently flows into the emulsification layer, so that the demulsifying agent is fully in contact with the emulsification layer and fully reacts with water-in-oil and oil-in-water in the emulsification layer, the emulsification layer is weakened, and normal dewatering of crude oil is kept.

Description

technical field [0001] The invention relates to the technical field of intelligent manufacturing, in particular to an emulsification treatment device for a crude oil dehydration settling tank. Background technique [0002] Settling tanks are mainly used for crude oil dehydration. [0003] The working principle of the existing settling tank is as follows: Figure 7-8 As shown, 23 is the oil layer, 13 is the middle layer (the middle layer slowly forms an emulsified layer through unbroken impurities), and 24 is the water layer. The crude oil flows into the settling tank from the oil inlet pipe first, and the injected crude oil rises from the bottom After separation, they are arranged from bottom to top into water layer, emulsified layer (the lower layer is water-in-oil, and the upper layer is oil-in-water), and oil layer. Since crude oil contains a large amount of water-in-oil and oil-in-water (oil-in-water) Water and oil-in-water contain asphalt, paraffin and other impurities...

[0003] The working principle of the existing settling tank is as follows: Figure 7-8 As shown, 23 is the oil layer, 13 is the middle layer (the middle layer slowly forms an emulsified layer through unbroken impurities), and 24 is the water layer. The crude oil flows into the settling tank from the oil inlet pipe first, and the injected crude oil rises from the bottom After separation, they are arranged from bottom to top into water layer, emulsified layer (the lower layer is water-in-oil, and the upper layer is oil-in-water), and oil layer. Since crude oil contains a large amount of water-in-oil and oil-in-water (oil-in-water) Water and oil-in-water contain asphalt, paraffin and other impurities), in order to remove water-in-oil and oil-in-water in crude oil, it is necessary to heat the crude oil to a certain temperature, and then add an appropriate amount of demulsifier to the crude oil regularly, and the demulsifier passes through The water in the crude oil diffuses into the oil layer and the water layer, and demulsifies the water-in-oil and oil-in-water in the emulsified layer (this technology is the existing technology), and the crude oil decreases with the temperature during the rising process, and the density of the crude oil Continuously increasing, blocking the dissolution of the demulsifier, resulting in the inability of the demulsifier to spread evenly, and the water-in-oil and oil-in-water (paraffin, asphalt and other impurities) that have not reacted with the demulsifier gather in the emulsified layer, making the asphalt inside the emulsified layer, Impurities such as paraffin become viscous. When the injected crude oil rises and contacts the emulsified layer, the temperature of the crude oil will be further reduced and the formation of the emulsified layer will be aggravated. , so that the demulsifier cannot diffuse into the water layer or the oil layer through the emulsified layer, causing the oil-in-water and water-in-oil in the water layer or the oil layer to fail to demulsify, and gather into the emulsified layer again, increasing the emulsified thickness of the emulsified layer, preventing Cut off the separation of oil and water, which seriously affects the dehydration efficiency of crude oil
