Description

Technical Field

[0001] This utility model relates to the technical field, specifically to an oil separator for process gas pipelines based on a novel adsorption material. Background Technology

[0002] In industries such as chemical, petroleum, natural gas, metallurgy, and power, process gases inevitably carry oil mist or droplets during production and transportation. These oily substances come from a wide range of sources, including compressor lubricating oil leaks, evaporation during the process, and other pollutants. If not removed promptly and effectively, they will cause serious damage to downstream equipment and processes. From an equipment perspective, oily substances can lead to wear and corrosion of equipment components, shortening equipment lifespan and increasing maintenance costs. For catalyst-dependent processes, oil can cause catalyst poisoning, reducing catalytic efficiency and affecting product quality. Environmentally, emissions of oily process gases cause air pollution and violate environmental regulations. Furthermore, the lack of effective oil recycling also results in energy waste.

[0003] Currently, traditional oil separators for process gas pipelines have many shortcomings. In terms of adsorption performance, they have low adsorption efficiency for tiny oil droplets (less than 1 micrometer), making it difficult to meet increasingly stringent purification requirements; the materials used are prone to failure under complex working conditions such as high temperature, high pressure, and corrosiveness, resulting in a short service life; moreover, frequent replacement and cleaning operations lead to high maintenance costs.

[0004] With the increasing demands for process gas purification in industrial production and the growing emphasis on energy conservation and environmental protection, there is an urgent need for a new type of process gas pipeline oil separator that can overcome the aforementioned problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides an oil separator for process gas pipelines based on a novel adsorption material, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an oil separator for process gas pipelines based on a novel adsorption material, comprising:

[0007] A primary filter, with an internal first adsorption layer and a first external threaded welded joint on top;

[0008] The secondary filter has a second adsorption layer inside and a second external threaded welded joint on the top.

[0009] The butt joint is used to connect the first external threaded welded joint and the second external threaded welded joint, so that the primary filter and the secondary filter form a series structure.

[0010] The first adsorption layer is used to remove large oil droplets, suspended matter, and some emulsified oil;

[0011] The second adsorption layer is used to adsorb residual tiny oil droplets and soluble oils.

[0012] Preferably, the first adsorption layer is a coarse adsorption layer made of modified activated carbon, oleophobic fiber or composite adsorption material.

[0013] Preferably, the second adsorption layer is a fine adsorption layer made of nanoscale adsorption materials, including functionalized molecular sieves and graphene composite materials.

[0014] Preferably, the first adsorption layer is a multi-layered fiber or porous structure used to intercept large particulate pollutants through a sieving effect.

[0015] Preferably, the second adsorption layer has an ultrafine pore structure to block residual oil, with a pore size of 0.1 to 0.5 μm.

[0016] Preferably, the first external threaded welded joint has an integrally formed first partition plate on the side near the butt joint, the first partition plate extends downward into the primary filter, and a first flow port is formed between the first partition plate and the primary filter;

[0017] The second external threaded welded joint has an integrally formed second partition plate on the side near the butt joint. The second partition plate extends downward into the secondary filter, and a second flow port is formed between the second partition plate and the secondary filter.

[0018] Beneficial effects

[0019] This invention provides an oil separator for process gas pipelines based on a novel adsorption material, which has the following beneficial effects:

[0020] Based on a two-stage filtration design, the first adsorption layer of the first-stage filter can effectively remove large oil droplets, suspended solids and some emulsified oil. The second adsorption layer of the second-stage filter uses nano-level adsorption materials, which have a strong adsorption capacity for tiny oil droplets and soluble oils. The oil removal rate can reach more than 99%, enabling the process media to reach a high cleanliness standard and meet the strict requirements of industrial production for the purification of process media.

[0021] Some adsorbent materials support online regeneration. Even if cleaning or replacement is required, the frequency is significantly lower than that of traditional oil separators. The adsorbent materials used have the characteristics of high temperature resistance and corrosion resistance, which can adapt to complex working conditions such as high temperature, high pressure and corrosiveness in chemical and petroleum industries. They are not prone to failure, effectively extending the service life of the oil separator and reducing the frequency of equipment replacement.

[0022] This oil separator is suitable for multiple industries such as chemical, petroleum, natural gas, metallurgy, and power. It can work stably and efficiently under various complex working conditions, whether it is processing different types of process media such as natural gas, syngas, or flue gas, and has strong versatility.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1 This utility model provides a technical solution: an oil separator for process gas pipelines based on a novel adsorption material, comprising:

[0027] The primary filter 1 has a first adsorption layer 102 inside and a first external threaded welding joint 101 on top;

[0028] The secondary filter 2 has a second adsorption layer 202 inside and a second external threaded welding joint 201 on the top.

[0029] The butt joint 3 is used to connect the first external threaded welding joint 101 and the second external threaded welding joint 201, so that the primary filter 1 and the secondary filter 2 form a series structure.

[0030] The first adsorption layer 102 is used to remove large oil droplets, suspended matter, and some emulsified oil;

[0031] The second adsorption layer 202 is used to adsorb residual tiny oil droplets and soluble oils.

[0032] In this embodiment, the first adsorption layer 102 is further configured to be a coarse adsorption layer made of modified activated carbon, oleophobic fiber or composite adsorption material.

[0033] In this embodiment, the second adsorption layer 202 is further configured to be a fine adsorption layer made of nanoscale adsorption materials, including functionalized molecular sieves and graphene composite materials.

[0034] In this embodiment, the first adsorption layer 102 is configured to be a multi-layer fiber or porous structure, used to intercept large particulate pollutants through a sieving effect.

[0035] In this embodiment, the second adsorption layer 202 is further configured to have an ultra-fine pore structure for blocking residual oil, with a pore size of 0.1 to 0.5 μm.

[0036] In this embodiment, the first external threaded welding joint 101 is provided with an integrally formed first partition 1011 on the side of the first external threaded welding joint 101 near the butt joint 3. The first partition 1011 extends downward into the interior of the primary filter 1, and a first flow port 1012 is formed between the first partition 1011 and the primary filter 1.

[0037] The second external threaded welding joint 201 has an integrally formed second partition 2011 on the side near the butt joint 3. The second partition 2011 extends downward into the secondary filter 2, and a second flow port 2012 is formed between the second partition 2011 and the secondary filter 2.

[0038] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0039] Example: During operation, oily media such as wastewater and compressed air first enter the primary filter 1, where large oil droplets, suspended solids and some emulsified oil are removed by the coarse adsorption layer. The coarse adsorption layer can be made of modified activated carbon, oleophobic fiber or composite adsorption material. The oil content of the medium after primary filtration is significantly reduced, but there may still be tiny oil mist or soluble oil.

[0040] The medium enters the secondary filter 2 and is finely filtered by the nano-scale adsorption materials of the second adsorption layer 202, such as functionalized molecular sieves and graphene composite materials, adsorbing residual small oil droplets with a particle size of <1μm and soluble oils. The medium after secondary filtration reaches a high cleanliness standard, such as oil content <1ppm, and can be directly reused or discharged.

[0041] Once the adsorbent material is saturated, it can be regenerated through thermal desorption, chemical cleaning, or filter replacement, depending on the material's characteristics. Some newer materials support online regeneration, reducing downtime.

[0042] In this application, the primary filter 1 employs a combination of physical adsorption and mechanical interception;

[0043] Adsorption mechanism: Novel oleophobic materials enhance their affinity for oils through surface modification and adsorb oil droplets using van der Waals forces, capillary action, and other mechanisms.

[0044] Interception mechanism: Multi-layer fiber or porous structures trap large particulate pollutants through a sieving effect.

[0045] Secondary filter 2: Chemical adsorption + deep filtration;

[0046] Chemisorption: Nanomaterials (such as silicon-based modifiers) bind to oil molecules through functional groups, efficiently capturing tiny oil mists.

[0047] Deep filtration: The ultra-fine pore structure (e.g., 0.1–0.5 μm) further blocks residual oil, ensuring ultra-low residue.

[0048] This application achieves an oil removal rate of >99% through a two-stage filtration design. The adsorption material used maintains high air permeability and water permeability even under high pressure, and some of the adsorption material can be recycled, reducing solid waste generation and making it convenient to use.
