Abstract
Description
Technical Field
[0001] The present application relates to a coke oven riser water seal device, belonging to the technical field of water seal devices. Background Art
[0002] The coke oven riser is the channel for the raw gas to be discharged during the coking process. A water seal device is designed on the top of the riser to seal the riser cover to prevent the raw gas from leaking from the riser cover. When the carbonization chamber is in the coking process, the riser cover is in a closed state, and a closed system is formed by the water seal riser cover. When the carbonization chamber is in the process of drying the oven before pushing the coke when the coke is mature, the riser cover is opened.
[0003] The water seal of the riser water seal cover must maintain a certain water level. If it is too high, it will easily overflow to the top of the coke oven. If it is too low, the raw gas will penetrate the water seal and cause leakage. Therefore, the water level requirement for the water seal of the riser water seal cover is relatively high. During coking production, impurities such as tar, tar residue, coke powder dust, etc. will enter the water in the water seal tank. If they are not cleaned out in time, a large amount of scaling will form in the water seal tank. Over time, it will not only affect the water seal effect, causing raw gas to overflow and pollute the environment, but also increase the difficulty of cleaning the water seal tank, resulting in increased labor intensity. In severe cases, the water seal seat needs to be replaced frequently, which increases production costs. Utility Model Content

[0035] Reference Figure 1-5 , introduces the coke oven riser water seal device according to the present application.
[0036] The coke oven riser water seal device according to this embodiment includes a water seal seat 1 and a water seal cover 2 arranged at the top of the riser 27. The water seal cover 2 is hinged to the water seal seat 1 through a driving assembly, which facilitates the opening or closing of the water seal cover 2, thereby improving the operating efficiency of the coke oven.
[0037] The water seal seat 1 is provided with a water seal groove 3, and the water seal groove 3 is provided with a drainage groove 4. The water seal groove 3 and the drainage groove 4 are separated by a vertical plate 5, which will not affect the water seal effect and ensure the normal use of the water seal groove 3; a sewage outlet 6 is provided at the bottom of the vertical plate 5, and a detachable plug 7 is provided in the sewage outlet 6, so as to clean out the dirt in the water seal groove 3 in time and prevent scaling;
[0038] A detachable filter assembly is provided in the drainage groove 4 to facilitate cleaning or replacement of the filter; a drain port 8 is provided at the bottom of the drainage groove 4, and a filter assembly cover is provided above the drain port 8 to filter the water in the water seal groove 3 and discharge the filtered water in time.
[0039] As an embodiment, the filter assembly includes a multi-layer filter screen 9 and a bolt, one end of the bolt is inserted into the multi-layer filter screen 9, and the multi-layer filter screen 9 is fixed by a first nut 10 and a second nut 11, thereby improving the stability and reliability of the filter assembly and ensuring that water still has stable filtering performance when passing through at high speed; the other end of the bolt is fastened with a third nut 12, which can serve as a handle to facilitate the removal and placement of the filter assembly.
[0040] In order to make the multi-layer filter screen 9 fit better with the bottom surface of the drain trough 4 to ensure the filtering effect, one end of the first nut 10 is fastened on the bolt and the first nut 10 is located in the drain port 8. At this time, the two also play a drainage role, which is conducive to the rapid discharge of filtered water.
[0041] As an implementation mode, the multi-layer filter 9 includes a first filter 91, a second filter 92 and a third filter 93 which are stacked in sequence from top to bottom. The aperture of the first filter 91 is larger than the aperture of the second filter 92, and the aperture of the second filter 92 is larger than the aperture of the third filter 93, thereby achieving graded filtration of impurities in the water and improving the filtration effect. At the same time, it reduces the damage caused by excessive pressure or filtering too many impurities to a single filter, which is beneficial to extending the service life of the filter component.
[0042] Specifically, the pore size of the first filter 91 is 4-5.5 mm, preferably 5 mm, for filtering coke dust; the pore size of the second filter 92 is 2.5-3.5 mm, preferably 3 mm, for filtering tar residue; the pore size of the third filter 93 is 0.5-1.5 mm, preferably 1 mm, for filtering tar.
[0043] As an embodiment, the sewage outlet 6 is tilted outward from top to bottom, and the lowest point of the sewage outlet 6 is located above the first filter screen 91, so that water and impurities can flow more smoothly from the water seal groove 3 to the drainage groove 4, avoiding the accumulation of impurities in the device.
[0044] As an implementation method, the upper edge of the vertical plate 5 is lower than the upper edge of the water seal groove 3, which acts as an overflow and can control the water level in the water seal groove 3 within a reasonable range, thereby preventing it from overflowing to the top of the coke oven due to being too high, and preventing it from losing the water seal effect due to being too low.
[0045] As an implementation mode, a water inlet groove 13 is also provided on the water seal groove 3, and the water inlet groove 13 is connected to the water seal groove 3, so as to facilitate timely replenishment of water into the water seal groove 3 to maintain the water level therein stable and ensure the normal operation of the coke oven.
[0046] As an implementation mode, a drain pipe 14 is connected to the drain outlet 8, a drain box 15 is provided at the end of the drain pipe 14 away from the drain trough 4, a water inlet box 16 is provided at the end of the drain box 15 away from the drain pipe 14, a water inlet pipe 17 is provided at the end of the water inlet box 16 away from the drain box 15, and the end of the water inlet pipe 17 extends to above the water inlet trough 13. With this arrangement, a water recycling system is formed, which realizes the effective use of water and helps to reduce production costs.
[0047] As an implementation method, a sewage pipe 28 is provided on the drainage box 15 to facilitate the discharge of water and impurities after secondary sedimentation, ensuring that the water circulating into the water inlet tank 13 is clean; the water inlet tank 16 is connected to the drainage box 15 through a circulation pipe 18, so that the clean water after secondary filtration can directly flow into the water inlet tank 16 to replenish the water seal tank 3, reducing the waste of water resources and improving water utilization efficiency.
[0048] Specifically, the drainage tank 15 is a secondary sedimentation tank, which has a clean water area 151 and a sedimentation area 152. The sewage pipe 28 is connected to the sedimentation area 152. A valve 19 is provided on the sewage pipe 28 to facilitate the discharge of settled water and impurities from the tank body. The circulation pipe 18 is connected to the clean water area 151 to transport clean water to the water inlet tank 16 for recycling.
[0049] As an embodiment, the driving assembly includes a telescopic cylinder 20, a counterweight 21 and a pin 22. The telescopic cylinder 20 is arranged on the riser 27, with a compact structure and a reasonable layout to control the opening and closing of the water seal cover 2; the water seal cover 2 is rotatably connected to the water seal seat 1 through the pin 22, and the end of the pin 22 away from the drain groove 4 is provided with a first connecting rod 23 and a second connecting rod 24. The first connecting rod 23 is hinged to the telescopic cylinder 20, and the counterweight 21 is passed through the second connecting rod 24, which increases the flexibility and stability of the overall structure, makes the water seal cover 2 more stable during the opening and closing process, and reduces unnecessary vibration and impact.
[0050] As an implementation mode, a plurality of first connecting holes 25 are opened on the second connecting rod 24, and a plurality of second connecting holes 26 are opened on the counterweight block 21. After the bolts pass through the first connecting holes 25 and the second connecting holes 26, the counterweight block 21 is connected to the second connecting rod 24. The position of the counterweight block 21 on the second connecting rod 24 can be flexibly adjusted to change the torque and balancing effect of the counterweight block 21.
[0051] The working principle of the coke oven riser water seal device according to this embodiment is:
[0052] Add clean water to the water inlet tank 16, and transport the clean water to the water inlet trough 13 through the water inlet pipe 17, and then flow from the water inlet trough 13 to the water seal trough 3. When the water level is the same as the height of the vertical plate 5, stop the water inlet, and the excess water overflows to the drainage trough 4 through the vertical plate 5, and after being filtered, flows to the drainage tank 15 through the drainage pipe 14. After secondary sedimentation, it flows into the water inlet tank 16 through the circulation pipe 18 for recycling. When the water level is lower than the height of the vertical plate 5, it continues to flow to the water seal trough 3 through the water inlet pipe 17. Water enters the groove 3 until the water level is the same as the height of the vertical plate 5; after a period of production, the water seal groove 3 is cleaned, at which time the telescopic cylinder 20 extends, driving the pin shaft 22 to rotate, the counterweight block 21 descends, the water seal cover 2 is opened, and the plug 7 is unplugged, so that water and impurities flow out from the sewage outlet 6 together, pass through the first filter screen 91, the second filter screen 92 and the third filter screen 93 in turn, and then flow to the drainage box 15. After secondary sedimentation, it flows into the water inlet tank 16 through the circulation pipe 18 for recycling.
