Abstract
Description
Technical Field
[0001] This utility model relates to the field of molecular oil-lock composite adsorption technology, specifically a molecular oil-lock composite adsorption structure for gas phase oil removal. Background Technology
[0002] Molecular oil-lock composite adsorption is an advanced purification technology specifically designed for the deep purification of molecular oil pollutants in the gas phase. Its core lies in constructing a multi-level synergistic adsorption system integrating physical adsorption, chemical catalysis, and molecular sieving. This structure typically combines materials with specific pore sizes and surface properties, such as molecular sieves, activated carbon, silica, special catalytic oxidants, or modified resins, in the form of multilayer or composite coatings to form a functionally partitioned adsorption bed. When oily gas passes through, the large-pore materials first capture oil mist and larger molecules. Subsequently, the small-pore molecular sieves or activated carbon, with their huge specific surface area and van der Waals forces, precisely "lock" and firmly adsorb the difficult-to-remove micro-oil molecules, like molecular locks. The catalytic layer then catalytically oxidizes some oil molecules in situ into harmless carbon dioxide and water, thereby completely eliminating oil pollution.
[0003] However, in practical industrial applications, graphene aerogel materials have low mechanical strength and are loose and fragile. They must be attached to a robust porous support frame to maintain their structural shape and withstand the impact of airflow. Therefore, the porous support frame composite is usually fixedly installed inside the adsorption tower. The gaseous molecular oil to be treated has a complex composition and often contains high-boiling-point heavy components, colloids, dust and other impurities. These substances will gradually deposit and block the microporous structure of the graphene aerogel during the adsorption process, causing its adsorption performance to drop sharply. Therefore, the graphene aerogel must be replaced regularly to ensure the stable operation of the system.
[0004] The current common practice is to permanently or semi-permanently fix porous support frames to designated locations on the inner wall of the tower body using welding, bolting, or complex snap-fit structures to ensure absolute structural stability under high-speed airflow and equipment vibration. While this fixing method ensures operational reliability, it creates significant difficulties for subsequent maintenance and replacement. When replacement is needed, operators must first shut down, depressurize, and purge the entire tower body, then remove the tower end caps or manholes, enter the narrow interior space, and, under limited visibility and operating conditions, unscrew numerous bolts or cut welds one by one to remove the support frame along with the adsorbent material. This entire process is not only time-consuming and labor-intensive, leading to prolonged production line downtime and significant economic losses, but also carries high risks due to working at heights or in confined spaces, placing extremely stringent demands on the skills and safety of operators. Therefore, a molecular oil-locking composite adsorption structure for gas-phase oil removal is proposed to address the aforementioned problems. Utility Model Content
[0005] To address the shortcomings of existing technologies, this invention provides a molecular oil-locking composite adsorption structure for gas-phase oil removal, which offers advantages such as improved convenience for replacing graphene aerogels. It solves the problem that with existing graphene aerogels, when replacement is needed, operators must first shut down, depressurize, and purge the entire tower, then disassemble the tower end caps or manholes, enter the narrow tower space, and, under limited visibility and operating conditions, unscrew numerous bolts or cut welds one by one to remove the support frame and adsorption material together.
[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0024] 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.
[0025] Please see Figures 1 to 4The molecular oil-locking composite adsorption structure for gas phase oil removal in this embodiment includes a base 1, a lower tower body 2 and an upper tower body 3, with an extraction structure provided between the lower tower body 2 and the upper tower body 3.
[0026] In this embodiment, the lower tower body 2 is fixedly connected to the top of the base 1, and the upper tower body 3 is movably connected to the top of the lower tower body 2.
[0027] In this embodiment, the extraction structure includes two cylinders 4 fixedly connected to the top of the base 1. The telescopic shaft of the cylinder 4 is fixedly connected to two connecting rods 5. The two connecting rods 5 are fixedly connected to the left and right sides of the lower tower body 2 respectively. The two cylinders 4 are symmetrically distributed on the left and right sides.
[0028] In this embodiment, a porous support frame 6 is slidably connected inside the lower tower body 2. The porous support frame 6 is filled with graphene aerogel 7. The porous support frame 6 is circular and has a cavity inside. The graphene aerogel 7 is filled inside the cavity. Notches are opened at the bottom and top of the graphene aerogel 7.
[0029] In this embodiment, a support ring 8 is fixedly connected inside the lower tower body 2, and a sealing ring 9 is fixedly connected to the inner circumferential wall of the upper tower body 3. The sealing ring 9 is slidably connected inside the lower tower body 2 and is located at the connection between the lower tower body 2 and the upper tower body 3.
[0030] In this embodiment, two limiting rods 10 are fixedly connected to the bottom of the sealing ring 9, and the porous support frame 6 is movably connected to the top of the support ring 8. Two slots are opened inside the porous support frame 6, and the limiting rods 10 are inserted into the slots. The size of the limiting rods 10 is adapted to the slots.
[0031] In this embodiment, two take-out seats 11 are fixedly connected to the top of the porous support frame 6. An inner rod 12 is fixedly connected inside the take-out seat 11. A circular groove is opened inside the take-out seat 11, and the inner rod 12 is located inside the circular groove. An air inlet pipe 13 is fixedly connected to the outer peripheral wall of the lower tower body 2, and a telescopic exhaust pipe 14 is fixedly connected to the top of the upper tower body 3.
[0032] It should be noted that, due to the core challenge of using graphene aerogel 7 directly in practical applications due to its low mechanical strength and porous, brittle texture, this technology proposes a sandwich structure. The core of this structure lies in a rigid, porous support frame 6, and the graphene aerogel 7 material filled and fixed within the cavity of this frame. This "constrained filling" design concept does not simply place the aerogel within the frame, but rather fundamentally solves the brittleness problem of the aerogel through the physical constraint of the frame.
[0033] It should be noted that the density or pore size of the graphene aerogel 7 inside the porous support frame 6 unit varies in a gradient. The pore size on the inlet side is larger to intercept large particles, while the pore size on the outlet side is smaller to adsorb molecular-level oil mist. This structure can significantly improve dust holding capacity and efficiency.
[0034] It should be noted that the two cylinders 4 are controlled synchronously by a controller.
[0035] The working principle of the above embodiments is as follows:
[0036] When it is necessary to remove the porous support frame 6 and graphene aerogel 7 from the interior of the lower tower body 2, the cylinder 4 is activated to move the upper tower body 3 upward via the connecting rod 5. After the sealing ring 9 is removed from the interior of the lower tower body 2, a hook tool is inserted into the interior of the removal seat 11. The hook tool is then connected to the inner rod 12. By pulling the hook tool upward, the porous support frame 6 and graphene aerogel 7 can be moved upward, allowing them to be removed and the graphene aerogel 7 to be replaced.
[0037] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods, and any method that achieves the desired beneficial effect can be implemented. Furthermore, all electrical components in this embodiment are electrically connected to the main controller and power supply. The main controller can be a conventional, known device such as a computer that performs control functions. Those skilled in the art can control the electrical components through simple programming, and the existing disclosed power connection technologies are common knowledge in the field. Therefore, this embodiment will not elaborate further on their specific structural composition and working principles.
