Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of filtering equipment, in particular to a nano aeration oil removal device. Background Art
[0002] At present, most of the methods used at home and abroad use the density method to separate oil and water, that is, liquid is injected into the box, and the oil floats on the water and separates naturally due to the different densities of oil and water. This method is very suitable for liquids with large differences in density. However, although liquids with similar densities can be separated, some oil is still dissolved in water or suspended in the liquid and cannot be effectively separated. Utility Model Content
[0003] The utility model aims to provide a nano aeration oil removal device to solve the problem in the prior art that part of the oil is dissolved in water or suspended in liquid and cannot be effectively separated.
[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:
[0005] A nano aeration oil removal device comprises a box body, on which four areas are arranged, including a maze area, an aeration area, an oil discharge area and a liquid discharge area; the maze area can reduce liquid disturbance; a nano bubble device is arranged at the bottom of the aeration area, and an oil blowing air knife is arranged at the top of the aeration area, and the oil blowing air knife can blow floating oil or impurities to the oil discharge area.
[0006] The nano-aeration oil removal device divides the box into four areas, including a maze area, an aeration area, an oil discharge area and a liquid discharge area. The liquid first enters the maze area, which can solve the turbulence problem of the liquid entering the box and better control the flow direction to improve the oil-water separation effect. After passing through the maze area, the liquid enters the aeration area. Nano bubbles are used in the aeration area to use the surface tension of the bubble film liquid to attach impurities and oil suspended in the liquid, solving the current problem of incomplete oil separation in the liquid. Then, the oil blowing air knife blows out an air curtain from time to time to blow the oil foam and the surface stratified oil to the oil collection area for collection and discharge. Finally, the treated liquid overflows to the liquid discharge area to complete the oil and impurity removal process.
[0007] As a preferred embodiment of the present utility model, an oil discharge port is provided at the bottom of the oil discharge area, a liquid outlet is provided at the upper part of the liquid discharge area, and a liquid inlet is provided at the lower part of the maze area. Since the oil blowing air knife blows out an air curtain from time to time to blow the oil foam and the surface stratified oil into the oil collecting chamber, the oil foam and the surface stratified oil will accumulate in the oil collecting chamber. The setting of the oil discharge port enables the floating oil in the oil collecting chamber to be discharged without clogging due to accumulation, thereby affecting the effect of oil and impurity removal.
[0008] As a preferred solution of the utility model, the four areas are separated by partitions, and the partitions include a first partition, a second partition and a third partition, and at least one overflow port is provided between the drainage area and the aeration area.
[0009] As a preferred solution of the utility model, at least two spoilers are arranged on the inner side of the maze area, and the spoilers are alternately arranged on the first partition and the box body. The setting of the spoiler solves the turbulent flow problem of liquid entering the box body and can better control the flow direction to improve the oil-water separation effect.
[0010] As a preferred embodiment of the present invention, the first baffle and the second baffle are both obliquely arranged on the bottom plate of the box body, and the height of the top of the first baffle is 10mm-30mm lower than the height of the top of the second baffle. The first baffle and the second baffle are both obliquely arranged on the bottom plate of the box body to separate the maze area and the aeration area. Since the liquid will enter the aeration area from the maze area and it is necessary to prevent the liquid from flowing into the oil drainage area, the height of the top of the first baffle must be lower than the height of the top of the second baffle, and setting the height difference between 10mm-30mm is best.
[0011] As a preferred solution of the utility model, the nano bubble device is arranged on the bottom plate of the box body and is located between the first baffle and the second baffle. The nano bubble device is arranged on the bottom of the box body and is located between the first baffle and the second baffle, so that a large number of fine bubbles generated can evenly cover the aeration area, and then the bubble surface will adhere to a large amount of suspended oil and impurities in the liquid and then float to the surface, so that the effect of nano bubbles adhering to floating oil and impurities is optimal.
[0012] As a preferred embodiment of the present invention, the height of the bottom position of the oil blowing air knife is 0mm-30mm higher than the height of the top of the first partition. In order for the oil blowing air knife to effectively blow floating oil or impurities to the oil discharge area, the bottom position of the oil blowing air knife should be higher than the liquid level. In order to make the angle between the wind curtain blown by the oil blowing air knife and the liquid level be at a suitable angle, the height difference is set between 0mm-30mm for the best effect.
[0013] As a preferred solution of the utility model, the oil blowing air knife is provided with an air nozzle, and the pitch angle of the air nozzle can be adjusted so that the angle between the air curtain blown out by the oil blowing air knife and the liquid surface can be adjusted, so that in actual use it can be adjusted according to the on-site conditions to ensure the best effect.
[0014] As a preferred solution of the utility model, three overflow ports are arranged on the second partition plate, the width of the overflow ports is 5 mm, and the overflow ports are arranged to transfer the treated liquid in the aeration zone to the drainage zone for discharge.
[0015] As a preferred embodiment of the present invention, the housing, the partition and the oil blowing air knife are all stainless steel components. Since the nano aeration oil removal device is always in contact with liquid during use, the housing, the partition and the oil blowing air knife are all set to be stainless steel components. On the one hand, the service life of the nano aeration oil removal device can be extended, and on the other hand, the nano aeration oil removal device can be prevented from rusting and causing liquid contamination.
[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:
[0017] 1. The nano-aeration oil removal device uses a first baffle, a second baffle and a third baffle to divide the box into four different areas, including a maze area, an aeration area, an oil discharge area and a liquid discharge area. The liquid first enters the maze area from the liquid inlet. A spoiler is arranged in the maze area to solve the turbulent flow problem of the liquid entering the box and better control the flow direction to improve the oil-water separation effect. After passing through the maze area, the liquid enters the aeration area. Nano bubbles are used in the aeration area to use the surface tension of the bubble film liquid to attach impurities and oil suspended in the liquid, solving the current problem of incomplete oil separation in the liquid. Then, the oil blowing air knife blows out an air curtain from time to time to blow the oil foam and the surface stratified oil to the oil collection area for collection and discharge. Finally, the treated liquid overflows to the liquid discharge area to complete the oil removal and impurity removal process.
[0018] 2. The nano-aeration oil removal device adopts a combination of semi-sealed chamber liquid labyrinth and nano-bubble adhesion to fully remove floating oil and impurities in the liquid. The physical separation method does not use consumables and the filtration is fast and efficient. BRIEF DESCRIPTION OF THE DRAWINGS
