Description

Technical Field

[0001] The utility model belongs to the technical field of oil-water separation equipment, and particularly relates to an oil-water emulsion separation device. Background Art

[0002] An oil-water separator is an instrument that separates oil and water. Most oil-water separators on the market are primarily designed to process immiscible oil-water solutions, but have difficulty effectively separating oil-water emulsions. In actual application scenarios, oil and water typically exhibit stratification due to their immiscible nature. However, due to the extensive use of emulsifiers in daily use, some of the oil in oily wastewater is distributed in the aqueous phase in the form of emulsified oil droplets. In addition, current oil-water separation filter elements are mostly made of metal or high molecular polymers, which have high energy consumption and cost, and their waste poses considerable challenges to environmental management.

[0003] Therefore, how to overcome the difficulties of high cost of oil-water separation devices in the existing technology, non-degradable filter element materials, unsatisfactory separation effects, and inability to effectively separate small-particle emulsified oils has become an urgent problem to be solved in current oil-water separation technology.

It uses a wood oil-water emulsion separation filter element as a filtering mechanism, can actively adsorb oil-water mixtures, and is particularly suitable for separating oil-water emulsions.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] An oil-water emulsion separation device comprises a housing and a wooden oil-water emulsion separation filter element arranged inside the housing. The wooden oil-water emulsion separation filter element comprises a wooden oleophilic component and a wooden hydrophilic component. Both the wooden oleophilic component and the wooden hydrophilic component have porous structures, and nano-scale pores are further provided on the side of the wooden hydrophilic component. The wooden oleophilic component is located above the wooden hydrophilic component.

[0007] Furthermore, the wooden oleophilic component is a cross-section slice of balsa wood that has been modified with silane, and the average pore size of the porous structure is 50 μm.

[0008] Furthermore, the wooden hydrophilic component is balsa wood that has been punched with holes parallel to the growth direction of the tree or balsa wood that has been punched with holes perpendicular to the growth direction of the tree.

[0009] Furthermore, the wooden oleophilic component and the wooden hydrophilic component are connected by glue, bolts and / or nails.

[0010] Furthermore, an oil extraction pipe is provided at the upper end of the box body, one end of the oil extraction pipe is connected to the pipe hole of the wooden oleophilic component, and the other end is connected to the oil depot.

[0011] Furthermore, a mixture feed pipe is provided at the lower end of the box body; the mixture feed pipe is connected to the pipe hole of the wooden hydrophilic component.

[0012] Furthermore, a water extraction pipe is provided at the lower end of the box body, and the opening of the water extraction pipe is always kept below the water surface.

[0013] Compared with the prior art, the utility model has the following advantages:

[0025] The present invention will be further illustrated below with reference to specific embodiments. The embodiments are implemented based on the technical solutions of the present invention. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention.

[0026] Example 1

[0027] like Figures 1 to 4 As shown, an oil-water emulsion separation device includes a box body 3, a wooden oil-water emulsion separation filter element 2, an oil extraction pipe 1, a mixture feed pipe 5 and a water extraction pipe 4.

[0028] The wood oil-water emulsion separation filter element 2 is housed within the housing 3. An oil extraction pipe 1 is located at the upper end of the housing 3, while a mixture feed pipe 5 and a water extraction pipe 4 are located at the lower end. The oil extraction pipe 1 is fixedly mounted at the upper end of the housing 3 and connected to the oil reservoir at the other end. This pipe is used to transport the oil separated from the wood oil-water emulsion separation filter element 2 within the housing 3 into the oil reservoir. The mixture feed pipe 5 is located at the lower end of the housing 3 and connected to a wastewater pipeline at the other end. This pipe can transport the oil-water emulsion from the wastewater pipeline to the wood oil-water emulsion separation filter element 2 within the housing 3 for subsequent oil-water separation.

[0029] The wood-based oil-water emulsion separation filter element 2 comprises a wood-based oleophilic component 6 and a wood-based hydrophilic component 7, which are tightly connected by gluing, bolting, or nailing. The wood-based oleophilic component 6 is made of a silane-modified cross-section of balsa wood and has a porous structure with an average pore size of 50 microns. This exhibits oleophilic and hydrophobic properties, repelling the water phase while actively adsorbing the oil phase. The oil phase rapidly penetrates the porous structure of the wood-based oleophilic component 6 and is discharged from the housing 3 through the oil extraction pipe 1 above.

[0030] The wooden hydrophilic component 7 is made of balsa wood with hydrophilic and oleophobic properties, and is perforated parallel to the growth direction of the tree to construct an oil-water mixture transmission channel. While having a porous structure, its side also has nano-scale pores, which exhibit hydrophilic and oleophobic properties. It can effectively isolate the oil phase in the oil-water mixture while allowing the water phase to quickly penetrate its porous structure, and then discharge the wood oil-water emulsion separation filter element 2 through the nano-scale pores on both sides and enter the box 3.

[0031] The moisture extraction pipe 4 is arranged at the bottom of the box body 3, one end of which is connected to the chamber of the box body 3, and the other end is provided with a valve. When the water level in the box body 3 reaches a certain level, the valve is opened to extract and discharge the moisture separated by the wood oil-water emulsion separation filter element 2 in the box body 3, thereby further realizing the continuous operation of the entire device.

[0032] Example 2

[0033] like Figure 1 and 5 As shown in Figures 1 to 7, an oil-water emulsion separation device includes a box body 3, a wooden oil-water emulsion separation filter element 2, an oil extraction pipe 1, a mixture feed pipe 5 and a water extraction pipe 4.

[0034] The wood oil-water emulsion separation filter element 2 is housed within the housing 3. An oil extraction pipe 1 is located at the upper end of the housing 3, while a mixture feed pipe 5 and a water extraction pipe 4 are located at the lower end. The oil extraction pipe 1 is fixedly mounted at the upper end of the housing 3 and connected to the oil reservoir at the other end. This pipe is used to transport the oil separated from the wood oil-water emulsion separation filter element 2 within the housing 3 into the oil reservoir. The mixture feed pipe 5 is located at the lower end of the housing 3 and connected to a wastewater pipeline at the other end. This pipe can transport the oil-water emulsion from the wastewater pipeline to the wood oil-water emulsion separation filter element 2 within the housing 3 for subsequent oil-water separation.

[0035] The wood oil-water emulsion separation filter element 2 consists of a wood oleophilic component 6 and a wood hydrophilic component 7, which are tightly connected by glue. The wood oleophilic component 6 is a silane-modified cross-section of balsa wood. It has a porous structure with an average pore size of 50 microns, exhibiting oleophilic and hydrophobic properties. It repels the water phase and actively absorbs the oil phase. The oil phase quickly penetrates the porous structure of the wood oleophilic component 6 and is discharged from the housing 3 through the oil extraction pipe 1 above.

[0036] The wooden hydrophilic component 7 is a block of balsa wood with hydrophilic and oleophobic properties. Holes are drilled perpendicular to the tree's growth direction to create a channel for the oil-water mixture. When the wooden hydrophilic component 7 comes into contact with the oil-water mixture, its surface's underwater oleophobic properties effectively isolate the oil phase, preventing it from infiltrating. Furthermore, due to its hydrophilic surface, the water phase is actively attracted to the wooden hydrophilic component 7 upon contact, entering the housing 3 through the wood's pores.

[0037] The moisture extraction pipe 4 is arranged at the bottom of the box body 3, one end of which is connected to the chamber of the box body 3, and the other end is provided with a valve. When the water level in the box body 3 reaches a certain level, the valve is opened to extract and discharge the moisture separated by the wood oil-water emulsion separation filter element 2 in the box body 3, thereby further realizing the continuous operation of the entire device.

[0038] The working principle of this utility model is:

[0039] When the utility model is used to separate oil-water emulsions, the waste liquid containing the oil-water emulsion enters the housing 3 through the mixture feed pipe 5. The wooden oil-water emulsion separation filter element 2 in the housing 3 is composed of a porous wooden hydrophilic component 7 and a wooden oleophilic component 6, and will quickly absorb the waste liquid. When the waste liquid passes through the wooden hydrophilic component 7, the side of the wooden hydrophilic component 7 contains nano-scale pores, which can effectively isolate the oil phase in the oil-water mixture, allowing the water phase to quickly penetrate the nano-scale pores and flow out of the wooden oil-water emulsion separation filter element 2 to reach the housing 3, thereby achieving oil-water separation. In addition, the water phase in the waste liquid will be repelled by the hydrophobicity of the wooden oleophilic component 6 located above the wooden hydrophilic component 7, while the oil phase is actively adsorbed by the oleophilic wooden oleophilic component 6 above. The oil phase quickly penetrates the porous structure of the wooden oleophilic component 6, is discharged through the pores above, enters the oil extraction pipe 1, and finally circulates to the oil depot. As the equipment runs and the filtering time increases, the water level in the box 3 gradually rises. At this time, the valve on the water extraction pipe 4 is opened, and the water can be discharged from the water extraction pipe 4 in time, thereby achieving efficient and continuous active filtration of the oil-water emulsion.

[0040] This utility model utilizes a wooden oil-water emulsion separation filter element 2, which actively absorbs oil-water mixtures and is particularly suitable for separating oil-water emulsions. This significantly reduces manufacturing costs and energy consumption, enhancing the product's environmental friendliness and aesthetic value. Sealing gaskets are provided at the joints, effectively improving the sealing performance of the housing and preventing water leakage. The opening of the water extraction pipe remains below the water surface, effectively preventing grease from being discharged with wastewater. This improves separation efficiency and quality, while also simplifying the overall structure and making it easy to use.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
