Description

Technical Field

[0001] This utility model relates to the field of coke-water separation technology, and more specifically, to a coke-water separation device. Background Technology

[0002] Coke lifters are typically installed in the adsorption tank or tower of an activated coke adsorption process to lift the activated coke to the discharge outlet. Because water and activated coke have different densities, they stratify within the adsorption tank (tower), with water on top and activated coke at the bottom. To improve the cleaning efficiency of the activated coke, the usual practice is to wash the coke first, then perform coke-water separation, discharging the wastewater after washing and recovering the cleaned activated coke. To enable the coke lifter to perform both coke washing and coke-water separation, the applicant has designed a coke lifter that integrates these two processes. The technical problem this invention aims to solve is how to separate the cleaned activated coke from the wastewater within this device. Utility Model Content

[0007] Preferably, the connector consists of a rib plate connected to the outer wall of the second tube and a retaining plate disposed at the bottom of the rib plate. The retaining plate is located at the bottom of the second tube and has a retaining head extending toward the central axis of the second tube.

[0014] Compared with the prior art, the present invention has at least the following beneficial effects:

[0015] During coke-water separation, the inlet is controlled by a switching valve. When the switching valve is open, the activated coke-water mixture flows into the overflow assembly from the inlet.

Detailed Implementation

[0022] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments, so that those skilled in the art can implement it based on the description.

[0023] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0024] like Figures 1-3 As shown, this utility model provides a coke-water separation device, including: a first pipe 1 with a backwash discharge port 2, an installation component at the bottom of the first pipe 1, and an overflow assembly inside the first pipe 1; the overflow assembly is connected to the installation component, and the overflow assembly has an inlet end 4 controlled by a switching valve 3. During coke-water separation, the inlet end 4 is controlled by the switching valve 3. When the switching valve 3 is open, the activated coke-water mixture flows into the overflow assembly from the inlet end 4. Under the action of gravity, the activated coke falls back into the adsorption tank (tower) from the overflow assembly, realizing the recovery of activated coke, while the wastewater in the coke-water mixture can overflow from the top of the overflow assembly, thereby entering the first pipe 1, and then being discharged outside the adsorption tank (tower) through the backwash discharge port 2 (the backwash discharge port 2 is connected to the sewage pipe).

[0025] Furthermore, the mounting component consists of a base plate 5 with an inlet hole and several connectors 6 located at the bottom of the base plate 5. One end of the overflow assembly is connected to the connector 6, and the other end passes through the inlet hole and extends into the first pipe 1. The overflow assembly consists of a second pipe 7, a first conical pipe 8, a second conical pipe 9, an installation pipe 10, and an overflow weir 11. The first conical pipe 8 is located at the bottom of the second pipe 7, and the top of the second pipe 7 extends into the inlet hole. The inner wall of the inlet hole is connected to the outer wall of the second pipe 7. Depending on the design of different products, the second pipe 7 and the inlet hole can be welded or plugged in. When the second pipe 7 and the inlet hole are connected by plugging in, the sealing of the second pipe 7 after plugging in the inlet hole should be ensured to prevent sewage from flowing back into the adsorption tank (tower) from the first pipe 1. Using plugging in can reduce the difficulty of cleaning, maintenance, and installation of the coke-water separation device. During cleaning, the second pipe 7 can be pulled out of the base plate 5, thus facilitating the cleaning of the overflow assembly. The bottom of the second tapered tube 9 is connected to the top of the second tube 7, and the top of the second tapered tube 9 is connected to the bottom of the mounting tube 10. The top of the mounting tube 10 is provided with the overflow weir 11. When the second tube 7 and the inlet hole are connected by a plug-in connection, the connector 6 consists of a rib 61 connected to the outer wall of the second tube 7 and a clamping plate 62 provided at the bottom of the rib 61. The clamping plate 62 is located at the bottom of the second tube 7 and has a clamping head extending towards the central axis of the second tube 7. The bottom of the second tube 7 abuts against the clamping head. The outer diameter of the second tube 7 is adapted to the inner diameter of the inlet hole. Thus, after the second tube 7 is inserted from the top of the base plate 5, the rib 61 limits the position of the outer wall of the second tube 7 in the horizontal direction, and the clamping head of the clamping plate 62 can support the second tube 7, thereby limiting the position of the second tube 7 in the vertical direction. The top opening diameter of the first tapered tube 8 is smaller than the bottom opening diameter, and the top opening diameter is smaller than the inner diameter of the second tube 7, while the bottom opening diameter is larger than the inner diameter of the second tube 7. The outer wall of the first tapered tube 8 is connected to the clamping plate 62 of the connecting member 6, such as... Figure 1 , 3As shown, activated coke slides down from the second tube 7 under gravity and lands on the outer wall of the first conical tube 8. It then slides outwards along the outer wall of the first conical tube 8, thus preventing the cleaned activated coke from falling into the adsorption tank (tower) and being repeatedly sucked in and cleaned by the coke lifter. The top opening diameter of the second conical tube 9 is larger than the bottom opening diameter, and the top opening diameter is larger than the inner diameter of the second tube 7, while the bottom opening diameter is adapted to the inner diameter of the second tube 7. The outer wall of the second conical tube 9 is connected to the top surface of the base plate 5 by several support members 12. The support members 12 are located on the top of the base plate 5 or on the outer wall of the second conical tube 9. Because activated coke exists inside the second conical tube 9, the support members 12 are provided to support the second conical tube 9 to prevent it from being bent and deformed. The inner diameter of the mounting tube 10 is adapted to the top opening diameter of the second conical tube 9, and a connecting plate 13 is provided at the top of the mounting tube 10. The overflow weir 11 is a ring-shaped structure formed by a toothed rack with teeth on its sides. The overflow weir 11 is circumferentially surrounding the outer wall of the mounting pipe 10, and both ends of the overflow weir 11 are connected to the connecting plate 13. The teeth of the overflow weir 11 are located at the top, and the teeth of the overflow weir 11 are higher than the backwash drain port 2. As the coke-water mixture continuously enters the overflow assembly from the inlet 4, the water level within the overflow assembly continuously rises. This is because the flow area of ​​the activated coke gradually decreases (from the opening area of ​​the installation pipe 10 to the surface area between the outer wall of the second pipe 7 and the outer wall of the first conical pipe 8; since the first conical pipe 8 is usually installed on the coke discharge pipe of the coke lifter, the flow area at the connection between the first conical pipe 8 and the second pipe 7 is the surface area between the inner wall of the second pipe 7 and the top outer wall of the first conical pipe 8). When the boundary between the activated coke and the wastewater reaches the top of the overflow weir 11, the wastewater can flow into the first pipe 1 through the gaps between the teeth and be discharged through the backwash drain port 2, while the activated coke can be blocked by the teeth, thus preventing the activated coke from overflowing. The overflow weir 11 is detachably installed on the installation pipe 10, allowing for vertical adjustment of the installation position. The installation height is usually slightly lower than that of the adsorption tank (tower).
