Description

Technical Field

[0001] The utility model relates to the technical field of marine oil processing devices, in particular to a compact marine oil micro-bubble oil removal device. Background Art

[0002] Petroleum refers to a mixture of gaseous, liquid and solid hydrocarbons with natural occurrence. Petroleum is divided into crude oil, natural gas, natural gas liquid and natural tar, but "petroleum" is still used as the definition of "crude oil". Petroleum is a viscous, dark brown liquid, known as the "blood of industry". Petroleum is stored in some areas of the upper crust. The main component is a mixture of various alkanes, cycloalkanes and aromatic hydrocarbons. In the processing of petroleum, it is necessary to use an oil removal device to remove the microbubbles carried in the petroleum.

[0003] However, the existing marine oil microbubble oil removal device can remove the bubbles in the oil through cyclone gas when in use, but the multiple circulation processing effect of oily wastewater in the device is not high, which reduces the removal amount of bubbles adsorbed in the oil, affecting the purity of the oil during oil processing.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a compact marine oil microbubble deoiling device is proposed. Utility Model Content

[0005] The utility model aims to provide a compact marine petroleum microbubble oil removal device to solve the problem in the above background technology that the multiple circulation processing effect of oily wastewater in the device is not high.

[0009] Furthermore, the second air inlets are symmetrically arranged on both sides of the outer cylinder.

[0010] Furthermore, petroleum wastewater can be injected into the first air inlet.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The utility model is provided with a first cyclone cylinder and a second cyclone cylinder. When the microbubbles in the marine oil are processed by the oil removal device, in order to improve the effect of multiple treatment of bubbles in the oil, the wastewater containing oil is injected from the first air inlet, and the gas is injected from the first air inlet, and the other and the oily wastewater are mixed and transported to the first cyclone cylinder respectively. The oil, water and gas work in the first cyclone cylinder, so that the fixed impurities are thrown to the tank wall and discharged from the first slag discharge port. At the same time, the oil and water form microbubbles and swirl upward, the lighter oil contains gas in the middle, and the water is in the middle. After exiting the conical inner cylinder, the oil and gas mechanically rise and are discharged from the first oil and gas outlet, and the water sinks to the inner wall gap of the outer cylinder for sedimentation, and enters the air inlet on the surface of the first partition plate and the second partition plate.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] Example: Figure 1-Figure 4 As shown, a compact marine petroleum microbubble oil removal device comprises an outer cylinder 1, a first air inlet 2 is arranged at the bottom of the outer cylinder 1, a first cyclone cylinder 3 fixedly connected to the top of the first air inlet 2 is fixedly connected to the inner wall of the outer cylinder 1, a first oil and gas outlet 4 is opened at the top of the outer cylinder 1, a first slag discharge port 5 penetrating the outer wall of the outer cylinder 1 is arranged on the outer wall of the first cyclone cylinder 3, a first baffle 6 is fixedly connected to the inner wall of the outer cylinder 1, a second baffle 7 located below the first baffle 6 is fixedly connected to the inner wall of the outer cylinder 1, a second air inlet 8 located below the first slag discharge port 5 is arranged on the outer wall of the outer cylinder 1, a second cyclone cylinder 9 located below the first cyclone cylinder 3 is fixedly connected to the inner wall of the outer cylinder 1, a second oil and gas outlet 10 penetrating the outer wall of the outer cylinder 1 is arranged on the top of the second cyclone cylinder 9, a second slag discharge port 11 penetrating the outer wall of the outer cylinder 1 is arranged on the outer wall of the second cyclone cylinder 9, and a water outlet 12 is arranged at the bottom of the outer cylinder 1.

[0020] Furthermore, the surfaces of the first partition plate 6 and the second partition plate 7 are provided with flow openings, which is beneficial for effectively circulating and transporting liquid water.

[0021] Furthermore, the outer wall contours of the first cyclone tube 3 and the second cyclone tube 9 are both conical, and cyclone distribution pipes are provided inside the first cyclone tube 3 and the second cyclone tube 9. Through the arrangement of the first cyclone tube 3 and the second cyclone tube 9, the liquid enters the cyclone tube and is subjected to the centrifugal action in the cyclone tube. The large particles in the liquid are thrown onto the wall of the centrifugal tube and slide radially along the wall. At this time, the structural design of the cyclone tube can make the cleaning water backwash the large particles and flush them out of the tube body. After cleaning, the large particles no longer hinder the cyclone separation of small particles. The small particles rise along the cyclone cone and leave the cyclone, thereby achieving the effect of effectively removing bubbles in oil and water.

[0022] Furthermore, the second air inlet 8 is symmetrically arranged on both sides of the outer cylinder 1, which is beneficial to facilitate the addition of gas to the secondary treated oil and water.

[0023] Furthermore, the first air inlet 2 can be used to inject petroleum wastewater, which is beneficial to the setting that the first air inlet 2 can be used to inject petroleum wastewater, and plays a role in facilitating the mixing of wastewater and gas and transporting them to the first cyclone tube 3.

[0024] Working principle: When using this compact marine oil microbubble oil removal device, when the microbubbles in the marine oil are processed by the oil removal device, in order to improve the effect of multiple treatment of bubbles in the oil, the oil-containing sewage is injected from the first air inlet 2, and the gas is injected from the first air inlet 2, and the other and oil-containing sewage are mixed and transported to the first cyclone tube 3 respectively. The oil, water and gas work in the first cyclone tube 3, so that the fixed impurities are thrown to the tank wall and discharged from the first slag discharge port 5. At the same time, the oil and water form microbubbles and swirl upward, the lighter oil-enclosed gas is in the middle, and the water is in the middle. After exiting the conical inner tube, the oil and gas mechanically rise and are discharged from the first oil and gas outlet 4, and the water sinks to the inner wall gap of the outer tube 1 and settles, and enters the air inlet on the surface of the first partition plate 6 and the second partition plate 7. At the same time, the remaining gas is transported to the second cyclone tube 9 for secondary processing and separation, and so on, to achieve the effect of multiple removal of bubbles in the oil and gas.

[0025] This is how this compact marine oil microbubble deoiling device works.
