Abstract
Description
Technical Field
[0001] This application belongs to the field of tar-ammonia-water separation technology, and specifically relates to a tar-ammonia-water separation device. Background Technology
[0002] The tar-ammonia water separator is a crucial piece of equipment in the coking production process, primarily used to separate tar, ammonia water, and tar residue generated during coal gas cooling. Specifically, after the coal gas is cooled in the primary cooler, the resulting mixture of tar, ammonia water, and tar residue enters the tar-ammonia water separator. In the separator, the mixture separates into three layers through settling: the upper layer is ammonia water, which overflows or is pumped into an intermediate ammonia water tank, and is then pumped back to the coke oven gas collecting pipe by a circulating ammonia water pump for cooling the crude coal gas. The middle layer is tar, which flows into the intermediate tar water tank through a level regulator and is finally pumped to the oil storage tank by a tar pump. The lower layer is tar residue, which settles at the bottom of the tank and is pumped to a mechanical scraper trough by a scraper conveyor or tar residue pump for periodic cleaning.
[0003] The tar-ammonia-water separation tank has an open conical funnel on its side. During oil level detection, the inspection hole on the side of the tank needs to be manually opened to allow the liquid in the tank to flow into the open conical funnel. The oil level is then determined by observing the liquid level within the funnel. After the oil in the open conical funnel is inspected, it produces an odor, which evaporates through the open opening, polluting the environment and affecting the health of workers. Summary of the Invention
[0004] To address the technical problem of oil evaporation from the open conical funnel during current tar-ammonia-water separation tank level detection, which pollutes the environment and affects the health of workers, this application provides a tar-ammonia-water separation device.

The clamping rod is hinged to the middle of the sealing cap, and one end of the clamping rod is hinged to the body to drive the sealing cap to switch between a sealing position and an observation position. The locking element is hinged to the body.
[0008] A venting trough is connected to the outlet.
[0009] When the sealing cover is in the sealing position, the oil viewing port is closed, and the locking member is connected to the other end of the clamping rod; when the sealing cover is in the observation position, the oil viewing port is open, and the locking member is separated from the clamping member.
[0010] In some embodiments, the oil viewing funnel further includes a rotating shaft and two supports, the two supports being spaced apart along the axial direction of the rotating shaft, each support including a connected crossbar and a longitudinal bar, the crossbar being connected to the outer side of the body, and the longitudinal bar being spaced apart from the body;
[0011] The two ends of the rotating shaft are respectively connected to the two longitudinal rods, and one end of the clamping rod is rotatably connected to the rotating shaft.

[0013] In some embodiments, the sealing cover has a hinge frame at its center, and the middle part of the clamping rod is rotatably connected to a hinge shaft located on the hinge frame; the sealing cover and the clamping rod are spaced apart.
[0014] In some embodiments, the other end of the clamping rod is provided with a groove, which extends through the clamping rod along the axial direction of the body;
[0015] The locking element includes a screw and a nut. The lower end of the screw is hinged to the body so that the middle part of the screw enters or leaves the slot. When the middle part of the screw enters the slot, the nut is threaded to the upper end of the screw and abuts against the top surface of the clamping rod.
[0016] In some embodiments, a washer is provided on the outer sleeve of the screw, the washer being located between the clamping rod and the nut.
[0017] In some embodiments, the body is cylindrical and the sealing cap is circular. When the sealing cap is in the sealing position, a sealing ring in a compressed state is provided between the sealing cap and the body.
[0018] In some embodiments, the sealing cover has an annular groove, and one side of the sealing ring along its own axial direction is located in the annular groove, while the other side abuts against the body.
[0019] In some embodiments, multiple oil inspection lines are provided, and the multiple oil inspection lines are arranged sequentially along the height direction, and each oil inspection line is equipped with a shut-off valve.
[0020] In some embodiments, five oil inspection lines are provided, and the five oil inspection lines are evenly distributed along the height direction.
[0021] The tar-ammonia-water separation device provided according to the embodiments of this application includes a separation tank, an oil viewing funnel, and a venting tank. The oil viewing funnel includes a body, a clamping rod, a sealing cap, and a locking element. The body has an oil viewing chamber and an oil viewing port, an inlet, and an outlet connected to the oil viewing chamber. The inlet is connected to the separation tank via an oil viewing pipe.

When the sealing cap is in the observation position, the oil viewing port is open, and the locking element separates from the clamping element.
[0022] The oil inspection funnel is equipped with a clamping rod, a sealing cap, and a locking mechanism. When oil inspection is required, the locking mechanism is released, and one end of the clamping rod rotates around the main body, causing the sealing cap to flip and open the inspection port. At this time, the operator can observe the water and oil content of the mixture in the oil inspection funnel through the inspection port. After oil inspection, one end of the clamping rod rotates back around the main body, causing the sealing cap to flip back and press against the edge of the inspection port. Then, the locking mechanism connects to the other end of the clamping rod, thereby locking the clamping rod and ensuring the airtightness between the sealing cap and the main body. This prevents the mixture or residue in the oil inspection funnel from evaporating into the surrounding environment, protecting the health of the operators and improving the surrounding environment.

Detailed Implementation
[0028] To enable those skilled in the art to more clearly understand this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.
[0029] This application provides a tar-ammonia-water separation device that can be set up in a closed manner when it is not necessary to determine the oil level, thereby avoiding the volatilization of the mixture or residue in the oil funnel and protecting the environment and the health of the workers.
[0030] This application is described below with reference to the accompanying drawings and specific embodiments:
[0031] Please see Figure 1 as well as Figure 2 The tar-ammonia-water separation device provided in this application includes a separation tank 10, an oil viewing funnel 30, and an venting tank 40.
[0032] The mixture of tar, ammonia, and tar residue in the separation tank 10 will stratify through static separation, with ammonia at the top, tar in the middle, and tar residue at the bottom. The measured oil level is the tar level. The oil viewing funnel 30 includes a body 31, a clamping rod 32, a sealing cover 33, and a locking element 34. The body 31 has an oil viewing chamber 311 and an oil viewing port, inlet, and outlet connected to the oil viewing chamber 311. The inlet is connected to the separation tank 10 through an oil viewing pipe 20. The clamping rod 32 is located above the sealing cover 33, with both ends extending out of the sealing cover 33. One end of the clamping rod 32 is hinged to the body 31 to switch the sealing cover 33 between the sealing position and the viewing position. The clamping rod 32 is hinged to the middle of the sealing cover 33. The venting tank 40 is connected to the outlet of the oil viewing funnel 30. With the sealing cover 33 in the sealed position, observe that the oil port is closed and the locking member 34 is connected to the other end of the clamping rod 32; with the sealing cover 33 in the observation position, observe that the oil port is open and the locking member 34 is separated from the clamping member.
[0033] The oil inspection funnel 30 is equipped with a clamping rod 32, a sealing cover 33, and a locking element 34. When oil inspection is required, the locking element 34 is released, and one end of the clamping rod 32 rotates around the body 31, thereby causing the sealing cover 33 to flip and open the inspection port. At this time, the operator can observe the water content and oil content of the mixture in the oil inspection funnel 30 through the inspection port. After oil inspection is completed, one end of the clamping rod 32 rotates back around the body 31, causing the sealing cover 33 to flip back and press against the edge of the inspection port. Then, the locking element 34 connects to the other end of the clamping rod 32, thereby locking the clamping rod 32 and ensuring the seal between the sealing cover 33 and the body 31.
[0034] The mixture in the separation tank 10 can flow into the oil observation funnel 30 through the oil observation pipe 20. If the mixture in the oil observation funnel 30 contains only oil and no water, it indicates that the oil level is higher than that in the oil observation pipe 20. If the mixture in the oil observation funnel 30 contains more water than oil, or only water, it indicates that the oil level is slightly lower than that in the oil observation pipe 20. After observing the amount of oil and water in the mixture in the oil observation funnel 30, the mixture in the oil observation funnel 30 is drained into the venting tank 40. At the same time, the sealing cover 33 is pressed tightly by the clamping rod 32. At this time, even if there is still a mixture remaining in the oil observation funnel 30, it cannot evaporate into the surrounding environment under the sealing cover 33, thus protecting the health of the workers.
[0035] The oil-viewing funnel 30 serves as a tool for operators to check the oil and water content of the mixture. Its inlet is located on the body 31, resulting in a simpler structure. If the inlet were located on the sealing cap 33, it would affect the rotation of the sealing cap 33 relative to the body 31. In some embodiments, the body 31 of the oil-viewing funnel 30 can be cylindrical, with the same diameter at both ends, providing a large volume to hold more of the mixture. This allows operators to more directly and quickly observe the oil and water content, thereby determining the oil level in the separation tank 10. In other embodiments, the body 31 can also be conical, wider at the top and narrower at the bottom, still allowing for the determination of the oil level in the separation tank 10 from the mixture.
[0036] In some embodiments, please refer to Figure 2 as well as Figure 3 The oil funnel 30 also includes a rotating shaft 36 and two supports 35. The two supports 35 are spaced apart along the axial direction of the rotating shaft 36. Each support 35 includes a connected horizontal bar 351 and a vertical bar 352. The horizontal bar 351 is connected to the outer side of the body 31, and the vertical bar 352 is spaced apart from the body 31. The two ends of the rotating shaft 36 are connected to the two vertical bars 352, and the first end of the clamping rod 32 is rotatably connected to the rotating shaft 36. The arrangement of the supports 35 and the rotating shaft 36 achieves a hinge between the clamping rod 32 and the body 31. The height of the rotating shaft 36 is higher than that of the sealing cover 33, and along the radial direction of the sealing cover 33, the rotating shaft 36 is offset from the sealing cover 33, that is, the rotating shaft 36 is located obliquely above the sealing cover 33. During the rotation of the sealing cover 33 by the clamping rod 32, the edge of the sealing cover 33 will not interfere with the body 31. In some embodiments, the horizontal bar 351 and the vertical bar 352 are perpendicular to each other, or the angle between the horizontal bar 351 and the vertical bar 352 is an obtuse angle.
[0037] In some embodiments, the inlet is located between two crossbars 351 (not shown in the figure). Generally, the oil viewing funnel 30 is open, and the outlet end of the oil viewing pipe 20 is directly positioned above the open end of the oil viewing funnel 30, allowing the mixture to enter the funnel 30 directly from the open end. Since this application includes a sealing cap 33, and the sealing cap 33 itself needs to rotate, placing the inlet on the sealing cap 33 would hinder its rotation if the oil viewing pipe 20 were directly connected to the sealing cap 33. Therefore, this application chooses to place the inlet on the body 31. However, the oil viewing funnel 30 itself is not a very large structure. The clamping rod 32, locking element 34, and bracket 35 occupy space on the outside of the body 31. Placing the inlet between the two crossbars 351 achieves the desired inlet arrangement while ensuring the inlet height is not too low. The oil viewing pipe 20 and the bracket 35 are located on the same side of the body 31, providing the best line of sight away from the bracket 35 during the flipping process, facilitating the operator's flipping operation and observation of the mixture.
[0038] In some embodiments, please refer to Figure 2 A hinge frame 37 is provided in the middle of the sealing cover 33, and the middle of the clamping rod 32 is rotatably connected to the hinge shaft 38 located on the hinge frame 37. The sealing cover 33 and the clamping rod 32 are spaced apart along the height direction. The middle of the sealing cover 33 is hinged to the clamping rod 32. When the sealing cover 33 rotates with the clamping rod 32 and approaches the oil viewing port edge of the body 31, it can adaptively adjust according to the shape of the port edge to improve the sealing effect. The sealing cover 33 itself bears the clamping force transmitted by the clamping rod 32 through the hinge shaft 38, and the clamping force is located in the middle of the sealing cover 33. Simultaneously, the sealing cover 33 is also subjected to an upward supporting force from the oil viewing port edge, and the supporting force is distributed in a ring shape, with the clamping force located within the ring. This ensures both the clamping effect of the sealing cover 33 towards the body 31 and ensures that the sealing cover 33 fits snugly against the port edge at all points, resulting in a good sealing effect.
[0039] In some embodiments, the other end of the clamping rod 32 is provided with a groove 321, which extends through the clamping rod 32 along the axial direction of the body 31; see also Figure 2The locking element 34 includes a screw 341 and a nut 342. The lower end of the screw 341 is hinged to the body 31 so that the middle part of the screw 341 enters or leaves the slot 321. When the middle part of the screw 341 enters the slot 321, the nut 342 is threadedly connected to the upper end of the screw 341 and abuts against the top surface of the clamping rod 32. One end of the screw 341 is hinged to the body 31 so that the screw 341 can rotate relative to the body 31, thereby switching back and forth between a first position and a second position. When the screw 341 is in the first position, the screw 341 is outside the slot 321, and the clamping rod 32 can rotate freely about the pivot 36. With the screw 341 in the second position, the screw 341 is set vertically, and the middle part of the screw 341 enters the slot 321. The end face of the nut 342 abuts against the top surface of the clamping rod 32, so that the clamping rod 32 is in a locked state, ensuring the seal of the sealing cover 33 on the oil port.
[0040] In other embodiments, the locking member 34 may also include a locking rod and a locking ring. The lower end of the locking rod is hinged to the body 31, and the upper end is connected to the locking ring. The locking ring can be sleeved on the other end of the pressing rod 32, thereby restricting the pressing rod 32 from moving upward, so that the pressing rod 32 is in a locked state, ensuring the sealing of the sealing cover 33 to the oil port.
[0041] In some embodiments, a washer 343 is fitted over the screw 341. The washer 343 is located between the clamping rod 32 and the nut 342, so that the nut 342 will not loosen and the sealing stability of the sealing cover 33 is improved.
[0042] In some embodiments, the sealing cap 33 is provided with an annular groove, one side of the sealing ring is located in the annular groove in the axial direction, and the other side abuts against the body 31, thereby improving the sealing effect between the sealing cap 33 and the oil viewing port and reducing tar diffusion.
[0043] In some embodiments, please refer to Figure 1 Multiple oil inspection lines 20 are provided, arranged sequentially along the height direction. Each oil inspection line 20 is equipped with a shut-off valve 21. During the oil level determination operation, the lowest shut-off valve 21 is opened first, and the state of the mixture inside the body 31 is observed. If the mixture contains only tar, the lowest shut-off valve 21 is closed, and the second shut-off valve 21 from the bottom is opened. The state of the mixture inside the body 31 is observed again. As long as the mixture contains only tar, the above steps are repeated until the mixture contains water, and the surface oil level is between the shut-off valve 21 opened this time and the shut-off valve 21 opened last time.
[0044] In some embodiments, five oil level monitoring lines 20 are provided, arranged sequentially along the height direction. This minimizes the number of lines and reduces the number of steps required for operators to determine the oil level, resulting in high efficiency and cost savings. Of course, eight or ten oil level monitoring lines 20 can also be provided to improve the accuracy of oil level determination.
[0045] The tar-ammonia-water separation device provided in this application has at least the following advantages:
[0046] (1) A sealing cover 33 is added to the existing open funnel, and the seal is locked by the clamping rod 32 and the locking part 34. Oil can be discharged first and then the cover can be opened to check the mixture in the oil funnel 30. After the inspection, the cover can be opened and sealed immediately, which effectively and quickly prevents the occurrence of odors and protects the environment and workers.
[0047] (2) Adjusting the conical funnel to a cylindrical shape increases the volume, allowing it to hold more mixtures. This makes it easier for operators to quickly identify the oil content in the mixture, thus improving work efficiency.
