Description

Technical Field

[0001] This utility model relates to the technical field of oil and gas recovery devices, and in particular to a membrane separation oil and gas recovery device. Background Technology

[0002] Membrane separation oil and gas recovery devices are equipment that use membrane technology to separate oil and gas mixtures. They are commonly used in the petroleum, natural gas, and chemical industries to recover and purify oil and gas resources, reduce environmental pollution, and improve resource utilization. These devices use semi-permeable membrane materials to separate different components in the oil and gas mixture, usually based on differences in molecular size, solubility, and polarity.

[0003] Oil and gas recovery devices include nanofiltration membrane devices. During the use of ultrafiltration membranes, grease and fine particulate matter easily accumulate on the membrane surface. Large particulate impurities in the oil and water directly enter the nanofiltration membrane device for treatment, increasing the frequency of membrane cleaning. Therefore, it is particularly important to design a membrane separation oil and gas recovery device. Utility Model Content

[0013] 1. This utility model comprises a first filter box, a fiber layer, a mesh layer, a filter bag layer, a second filter box, and an inlet pipe. Oil and water are guided to the interior of the pretreatment box through a guide pipe, and then to the surface of the fiber layer, mesh layer, and filter bag layer through a transport pipe.

[0020] Please see Figure 1-3 This utility model provides a technical solution for a membrane separation oil and gas recovery device:

[0021] Example 1:

[0022] like Figure 1-2 As shown, a membrane separation oil and gas recovery device includes an ultrafiltration membrane device body 1 and a discharge pipe 2. The discharge pipe 2 is located on the top of the ultrafiltration membrane device body 1. The device is characterized by: a pretreatment box 3 on one side of the ultrafiltration membrane device body 1, a guide pipe 4 connected to one side of the pretreatment box 3, four shelf plates 7 inside the pretreatment box 3, two of which have a first filter box 8 on their tops, a fiber layer 9 inside the first filter box 8, a mesh layer 10 inside the first filter box 8, and a filter bag layer 11 inside the first filter box 8.

The fiber layer 9 is made of polyester fiber material and its main function is to filter pollutants in the air through physical action. The mesh layer 10 is made of plastic filaments and its main function is to enhance the structural strength and prevent deformation and damage of the filter layer during use. The filter bag layer 11 is made of polyester material and can screen out larger diameter solid particles and suspended matter, preventing them from directly entering the ultrafiltration membrane device body 1 and reducing membrane fouling.

[0023] Example 2:

[0024] Based on Example 1, such as Figure 1 and Figure 3 As shown, the top of the other two shelving plates 7 is supported by a second filter box 15. An inlet pipe 5 is provided on one side of the ultrafiltration membrane device body 1. Multiple transport pipes 6 are interwoven and connected to the outer wall of the guide pipe 4. The fiber layer 9 and the mesh layer 10 are hot-pressed together. By setting the guide pipe 4, transport pipe 6, flame retardant layer 12 and sound insulation layer 13, the oil and water are pre-filtered inside the pretreatment box 3 and then continue to be guided to the inside of the second filter box 15 for sedimentation.

The settled oil and water will be guided to the inside of the ultrafiltration membrane device body 1 through the inlet pipe 5 to realize subsequent oil and gas recovery.

[0025] Working Principle: A membrane separation oil and gas recovery device is a device that uses membrane technology to separate oil and gas mixtures. It is commonly used in the petroleum, natural gas, and chemical industries to recover and purify oil and gas resources, reduce environmental pollution, and improve resource utilization. This device uses semi-permeable membrane materials to separate different components in the oil and gas mixture, typically based on differences in molecular size, solubility, and polarity. The oil and gas recovery device includes a nanofiltration membrane unit. During the use of ultrafiltration membranes, grease and fine particulate matter easily accumulate on the membrane surface. Large particles of impurities in the oil and water directly enter the nanofiltration membrane unit for treatment, increasing the frequency of membrane cleaning. Therefore, designing a membrane separation oil and gas recovery device is particularly important. Oil and water are guided to the interior of the pretreatment tank 3 through the guide pipe 4, and then to the surface of the fiber layer 9, mesh layer 10, and filter bag layer 11 through the transport pipe 6. The fiber layer 9 is made of polyester fiber. Made of various materials, its main function is to filter air pollutants through physical action. The mesh layer 10 is made of plastic filaments, which mainly serves to enhance the structural strength and prevent deformation and damage of the filter layer during use. The filter bag layer 11 is made of polyester material, which can screen out large-diameter solid particles and suspended matter, preventing them from directly entering the ultrafiltration membrane device body 1 and reducing membrane fouling. After pre-filtration in the pretreatment tank 3, the oil and water are continued to be guided to the interior of the second filter tank 15 for sedimentation. Gravity is used to separate large particles in the raw water and reduce the concentration of suspended matter in the water. The settled oil and water will be guided to the interior of the ultrafiltration membrane device body 1 through the inlet pipe 5 to achieve subsequent oil and gas recovery. The flame retardant layer 12 is made of fireproof board material, which plays a role in preventing the spread of fire. The sound insulation layer 13 is made of sound-absorbing cotton, forming a sound insulation interlayer, which can reduce the transmission of sound through the box wall.
