Description

Technical Field

[0001] This utility model relates to the field of activated carbon filter technology, specifically to a spiral guide tube for an activated carbon oil remover. Background Technology

[0002] Activated carbon oil separators are key devices that utilize the adsorption properties of activated carbon to purify oily media. They are widely used in industries such as petrochemicals, machinery manufacturing, food processing, and metal smelting, and also play an important role in municipal wastewater treatment and marine oil spill treatment. Their core working principle is to leverage the abundant microporous structure and large specific surface area of ​​activated carbon to adsorb and retain oil in oily liquids through physical and chemical adsorption, ensuring that the treated liquid meets discharge or reuse standards.

[0003] In actual operation, the processing efficiency of activated carbon oil separators is closely related to the flow state and contact uniformity of the oily liquid in the activated carbon layer. However, existing activated carbon oil separators have structural design flaws, especially in the lack of a scientifically sound guiding mechanism for liquid flow. Specifically, the oily liquid to be filtered usually enters the oil separator directly through a single inlet. Under pressure or gravity, the liquid often impacts the central area of ​​the activated carbon layer in a relatively concentrated stream.

[0004] This direct impact method causes a series of problems: First, the liquid creates a strong scouring effect in the central area of ​​the activated carbon layer, causing the activated carbon in that area to quickly reach adsorption saturation, while the activated carbon in the surrounding areas remains idle because the liquid cannot fully penetrate, resulting in extremely low surface utilization of the activated carbon. Second, after the central area is excessively impacted, the activated carbon particles are prone to compaction and caking, which increases the flow resistance of the liquid in that area, further exacerbating the uneven distribution of the liquid within the activated carbon layer. Some liquid may even flow out along the gap between the inner wall of the oil separator and the activated carbon layer without effective adsorption treatment, directly affecting the overall filtration efficiency and making it difficult to consistently meet the oil concentration standards of the treated liquid.

[0005] Therefore, a spiral guide tube for an activated carbon oil separator is proposed to optimize the flow path of oily liquid in the activated carbon oil separator, avoid direct impact of liquid on the center of the activated carbon layer, and improve the utilization rate and filtration efficiency of the activated carbon surface. Utility Model Content

[0006] The purpose of this invention is to provide a spiral guide tube for an activated carbon oil separator to solve the problems mentioned in the background art.

[0007] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0008] An activated carbon oil separator spiral guide tube includes a separation tank. Three sets of support rods are evenly installed on the outer circumference of the separation tank. The top of the separation tank is connected to a feed inlet, and a flange is installed at the top of the feed inlet. The interior of the separation tank is filled with an activated carbon layer. The side of the separation tank is connected to a discharge outlet near its bottom. The interior of the separation tank is provided with pipes arranged vertically and connected to the feed inlet. A disc-shaped spiral tube is connected to the outer side of the pipes and is located above the activated carbon layer. The bottom surface of the disc-shaped spiral tube has several through holes spirally distributed. The disc-shaped spiral tube and the through holes on the bottom surface can make the oily liquid evenly distributed above the activated carbon layer, avoiding the liquid from concentrating and impacting the central area of ​​the activated carbon layer, thereby improving the utilization rate of the activated carbon layer.

[0009] Furthermore, both the pipe and the disc-shaped spiral tube are hollow. An opening is provided on the side of the pipe, and one end of the disc-shaped spiral tube is connected to the opening. The hollow shape of the pipe and the disc-shaped spiral tube facilitates the flow of oily liquids. The opening on the side of the pipe is connected to the disc-shaped spiral tube, which can smoothly guide the liquid in the pipe into the disc-shaped spiral tube, ensuring the continuity of liquid transportation.

[0010] Furthermore, a fixing ring is installed at one end of the disc-shaped spiral tube and on the outside of the pipe near the opening. The fixing rings are connected by screws. The connection between the fixing rings and screws makes the disc-shaped spiral tube and the pipe firmly connected. Under the circumstances of gas pressure rise and liquid flow impact force in the separation tank, the connection between the two can be prevented from loosening, ensuring stable operation of the equipment.

[0011] Furthermore, a support block is installed on the outer side of the disc-shaped spiral tube, and the support block is connected to the inner wall of the separation tank. The support block can support the disc-shaped spiral tube, preventing it from deforming or shifting in position under its own weight and the weight of the liquid, ensuring its stable position above the activated carbon layer, and ensuring that the liquid can drip evenly onto the activated carbon layer.

[0012] Furthermore, a bottom cover is installed on the bottom surface of the separation tank, a connecting frame is installed inside the bottom cover, a screen is installed inside the connecting frame, and a slag discharge port is connected to the bottom surface of the bottom cover.

[0013] Furthermore, a sealing ring is installed on the top surface of the bottom cover, and bolts connect the bottom cover and the separation tank. The sealing ring enhances the sealing between the bottom cover and the separation tank, prevents gas and liquid leakage from the separation tank, and ensures the pressure-boosting effect of the separation tank as a pressure vessel. The bolts make the bottom cover and the separation tank firmly connected, ensuring that the bottom cover will not loosen under the pressure inside the separation tank, and ensuring the safe operation of the equipment.

[0014] Furthermore, the side of the separator has an air outlet above the activated carbon layer and an air inlet below the activated carbon layer. The air inlet allows gas to be introduced into the separator, increasing the pressure inside the separator, accelerating the flow of oily liquid inside the separator, and improving the oil removal efficiency. The air outlet allows excess gas to be discharged from the separator, regulating the pressure inside the separator, preventing excessive pressure from damaging the equipment, and ensuring safe operation of the equipment.

[0015] Compared with existing technologies, the beneficial effects of this invention are as follows: The spiral guide pipe of this activated carbon oil separator, through the cooperation of vertically arranged pipes and a disc-shaped spiral tube, allows oily liquid to enter through the inlet and be evenly dispersed above the activated carbon layer via spirally distributed through-holes on the bottom surface of the disc-shaped spiral tube, avoiding the situation where liquid concentrates and impacts the central area of ​​the activated carbon layer. This ensures that all areas of the activated carbon layer can uniformly contact the oily liquid, reducing the phenomenon of rapid saturation of the activated carbon in the central area while the surrounding areas remain idle, thus improving the utilization rate of activated carbon. Simultaneously, uniform contact allows the oily liquid to more fully contact all areas of the activated carbon layer, reducing the situation where liquid flows out before sufficient adsorption, thereby improving the purification effect on the oily liquid. The combined effect of improved purification effect and increased throughput per unit time results in improved filtration efficiency. Attached Figure Description

[0021] 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.

[0022] Please see Figure 1 - Figure 4 This utility model provides a technical solution: an activated carbon oil separator spiral guide pipe, including a separation tank 1. Three sets of support rods 4 are installed at equal intervals around the outer circumference of the separation tank 1. The top of the separation tank 1 is connected to an inlet 2, and a flange 5 is installed at the top of the inlet 2. The interior of the separation tank 1 is filled with an activated carbon layer 9. The side of the separation tank 1 is connected to an outlet 11 near its bottom. The interior of the separation tank 1 is provided with a pipe 6, which is arranged vertically and connected to the inlet 2. The outer side of the pipe 6 is connected to a disc-shaped spiral tube 7, which is located above the activated carbon layer 9. The bottom surface of the disc-shaped spiral tube 7 has a plurality of through holes 16 spirally distributed. Oily liquid enters the pipe 6 through the inlet 2 and then flows into the disc-shaped spiral tube 7, and drips evenly onto the activated carbon layer 9 through the spirally distributed through holes 16 on the bottom surface. The separation tank 1 acts as a pressure vessel. The internal pressure is increased by gas pressurization, which pushes the liquid to flow in the tank. The oil in the liquid is adsorbed by the activated carbon layer 9, and the treated liquid is discharged from the outlet 11. The three sets of support rods 4 provide support and fixation for the separator 1, and the flange 5 achieves a sealed connection between the feed inlet 2 and the external pipeline.

[0023] As an embodiment of this utility model, both the pipe 6 and the disc spiral tube 7 are hollow. The side of the pipe 6 is provided with an opening, and one end of the disc spiral tube 7 is connected to the opening. After the oily liquid enters the vertically arranged pipe 6 from the inlet 2, it flows into the disc spiral tube 7 connected to it through the opening on the side of the pipe 6, thereby realizing the transportation of liquid from the pipe 6 to the disc spiral tube 7.

[0024] As an embodiment of this utility model, a fixing ring is further installed at one end of the disc-shaped spiral tube 7 and the outer side of the pipe 6 near the opening. The fixing rings are connected by screws. By installing fixing rings at one end of the disc-shaped spiral tube 7 and the outer side of the pipe 6 near the opening and connecting the fixing rings with screws, the fastening force of the screws makes the disc-shaped spiral tube 7 and the pipe 6 stably connected, preventing them from separating due to pressure changes or liquid impact during equipment operation.

[0025] As an embodiment of this utility model, a support block 8 is further installed on the outer side of the disc-shaped spiral tube 7, and the support block 8 is connected to the inner wall of the separation tank 1. One end of the support block 8 is connected to the outer side of the disc-shaped spiral tube 7, and the other end is connected to the inner wall of the separation tank 1. With the help of the fixed structure of the separation tank 1, the support force is provided for the disc-shaped spiral tube 7, balancing the weight of the disc-shaped spiral tube 7 itself and the internal liquid, and maintaining its stable spatial position.

[0026] As an embodiment of the present invention, the bottom surface of the separation tank 1 is further provided with a bottom cover 12, a connecting frame 14 is installed inside the bottom cover 12, a screen is installed inside the connecting frame 14, and the bottom surface of the bottom cover 12 is connected to a slag discharge port 13.

[0027] As an embodiment of this utility model, a sealing ring is further installed on the top surface of the bottom cover 12, and a bolt 15 is connected between the bottom cover 12 and the separation tank 1. The bottom cover 12 is connected to the separation tank 1 by the bolt 15. The tightening force of the bolt 15 makes the bottom cover 12 fit tightly against the bottom of the separation tank 1. At the same time, the sealing ring on the top surface is squeezed to fill the gap between the two, thereby achieving a sealing effect, preventing gas and liquid leakage in the separation tank 1, and ensuring that the tank can be pressurized normally.

[0028] In one embodiment of this utility model, the side of the separator 1 has an outlet 3 located above the activated carbon layer 9, and an inlet 10 located below the activated carbon layer 9. Gas is introduced into the separator 1 through the inlet 10. Since the separator 1 is a pressure vessel, the gas accumulates inside the tank, increasing the pressure and driving the oily liquid to flow within the tank, thus improving the contact efficiency between the liquid and the activated carbon layer 9. When the pressure inside the tank is too high, excess gas is discharged from the outlet 3, maintaining the pressure inside the tank within a safe range.

[0029] It should be noted that all standard parts used in this application can be purchased from the market, and can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. The control method is automatic control through a control cabinet. The control circuit can be implemented by simple programming by those skilled in the art and is common knowledge in the field. Furthermore, since this application is mainly used to protect mechanical devices, this application will not explain the control method and circuit connection in detail.
