DETAILED DESCRIPTION

[0032] The utility model is further described below in conjunction with the accompanying drawings and embodiments. Example

[0033] A coke oven gas condensate recycling device, see Figure 1-Figure 5As shown, it includes a first support frame 1, a mixing barrel 2, a second support frame 3, a water tank 4, a diverter pipe 8, a second ball valve 801, a guide pipe 1101, a third ball valve 1102 and a collecting frame 1103. The mixing barrel 2 is installed in the middle of the upper part of the first support frame 1 by bolt connection, and the second support frame 3 is installed on the top of the mixing barrel 2 by bolt connection. The water tank 4 for containing coke oven gas condensate is installed in the middle of the upper part of the second support frame 3 by bolt connection. The bottom of the water tank 4 and the top of the mixing barrel 2 are commonly connected and connected with the diverter pipe 8. The diverter pipe 8 is a three-way pipe, which is convenient for diverting the coke oven gas condensate in the water tank 4 into the mixing barrel 2 to avoid the failure of normal water supply after the single pipe is blocked. The diverter pipe 8 is rotatably provided with a second Ball valve 801, the bottom of the mixing barrel 2 is connected and communicated with a guide pipe 1101, and a third ball valve 1102 is rotatably arranged on the guide pipe 1101. A collecting frame 1103 for collecting filtered condensed water is placed on the top surface of the first support frame 1, and the water in the mixing barrel 2 flows into the collecting frame 1103 through the guide pipe 1101. It also includes an air guide pipe 5, an air outlet pipe 6, a first ball valve 7 and a stirring component for stirring and fully mixing the coke oven gas condensed water and ammonia. One side of the mixing barrel 2 is connected and communicated with an air guide pipe 5 for introducing ammonia, and the air guide pipe 5 extends to the bottom of the mixing barrel 2. The other side of the mixing barrel 2 is connected and communicated with an air outlet pipe 6 for discharging exhaust gas. The air guide pipe 5 and the air outlet pipe 6 are both rotatably arranged with the first ball valve 7, and a stirring component is arranged in the mixing barrel 2.

[0034] See also Figure 2 As shown, the stirring assembly includes a diverter plate 9, a first motor 10 and a stirring frame 11. The diverter plate 9 is installed on the upper part of the mixing barrel 2 by welding, and is provided with a number of evenly distributed through holes for water passing. The first motor 10 is installed on one side of the bottom of the diverter plate 9 by bolting. The output shaft of the first motor 10 faces downward, and the lower part of the output shaft of the first motor 10 is fixedly connected to the stirring frame 11 by bolting. The stirring frame 11 has three blades, and the stirring frame 11 extends to the lower part of the mixing barrel 2. The stirring frame 11 is driven by the first motor 10 to stir the falling ammonia and coke oven gas condensate.

[0035] When the coke oven gas condensate is to be filtered, the coke oven gas condensate is first introduced into the water storage tank 4, and ammonia is introduced into the mixing barrel 2 from the air guide pipe 5. At this time, the first ball valve 7 on the air guide pipe 5 is kept open, and the air outlet pipe 6 on the air outlet pipe 6 is closed. Then, the second ball valve 801 is turned to open, so that the coke oven gas condensate in the water storage tank 4 falls on the diverter plate 9 through the diverter pipe 8, and the coke oven gas condensate is dispersed and sprinkled through the through holes of the diverter plate 9. At the same time, the first motor 10 is started to drive the stirring frame 11 to rotate, so that the stirring The mixing frame 11 fully mixes the coke oven gas condensate and ammonia to reduce the viscosity of the tar contained in the coke oven gas condensate and reduce the sticky tar and impurities in the mixing barrel 2. After the mixing is completed, the first motor 10 is turned off, and then the third ball valve 1102 is opened. The treated coke oven gas condensate flows from the guide pipe 1101 into the collection frame 1103. After the collection is completed, the second ball valve 801 and the first ball valve 7 on the air guide pipe 5 are closed, and the first ball valve 7 of the outlet pipe 6 is opened to discharge the exhaust gas in the mixing barrel 2. Example

[0036] Based on Example 1, see Figure 6 and Figure 7 As shown, it also includes a fixing frame 12, a connecting frame 13, a support rod 14, a filter screen 15 and a first elastic member 16. The middle part of the shunt pipe 8 is fixedly sleeved with the fixing frame 12 by bolt connection. Support rods 14 are slidably arranged on both sides of the fixing frame 12. The middle parts of the two support rods 14 are fixedly connected with the connecting frame 13 by welding. The connecting frame 13 is slidably connected to the shunt pipe 8. The connecting frame 13 is pulled to drive the two support rods 14 to slide along the fixing frame 12. Two first elastic members 16 are fixedly connected between the connecting frame 13 and the fixing frame 12 by welding. The two first elastic members 16 are respectively wound around the two support rods 14. The two support rods 14 penetrate into the shunt pipe 8, and the bottoms of the two support rods 14 are fixedly connected with the filter screen 15 by welding. The filter screen 15 is located in the shunt pipe 8. When the support rod 14 moves upward, the filter screen 15 is pulled out of the shunt pipe 8.

[0037] As the usage time increases, more impurities will remain in the shunt pipe 8. To avoid blockage of the shunt pipe 8, the staff can pull the connecting frame 13 upwards, and the connecting frame 13 drives the support rods 14 on both sides to slide upwards along the fixing frame 12. At this time, the two first elastic members 16 are compressed, and the filter screen 15 is pulled out of the shunt pipe 8 by the support rods 14, and then the impurities brought out of the filter screen 15 are cleaned. After the cleaning is completed, the connecting frame 13 is released, and the first elastic member 16 loses the force and returns to its original state, pushing the connecting frame 13 to slide downward and reset, so that the support rods 14 drive the filter screen 15 to slide into the shunt pipe 8.

[0038] See also Figure 8 and Fig. 9As shown, it also includes a filter plate 17, a guide frame 18, a first guide rod 19 and a second elastic member 20. The filter plate 17 is slidably arranged on the guide tube 1101. The filter plate 17 is a multi-layer structure so that the filter plate 17 can fully filter the coke oven gas condensate water and make the coke oven gas condensate water recyclable. The guide frame 18 is installed at the lower side of the mixing barrel 2 by bolt connection. The first guide rod 19 is slidably arranged on the guide frame 18. The first guide rod 19 drives the filter plate 17 to slide horizontally on the guide frame 18. The first guide rod 19 is fixedly connected to the filter plate 17 by bolt connection. The second elastic member 20 is wound around the first guide rod 19. The second elastic member 20 is used to push the guide rod to fix the filter plate 17 on the guide tube 1101.

[0039] When the coke oven gas condensate is mixed with ammonia, as the third ball valve 1102 is opened, the mixed water will pass through the guide pipe 1101. At this time, the mixed water passes through multiple filtrations of the filter plate 17 to filter out ammonia and other impurities, and then falls into the collection frame 1103. When the filter plate 17 needs to be replaced after long-term use, the first guide rod 19 is pulled to drive the filter plate 17 to slide on the guide frame 18 to the side away from the guide pipe 1101, so that the filter plate 17 is pulled out of the guide pipe 1101. At this time, the second elastic member 20 is compressed and deformed, and then the filter plate 17 is replaced. After the replacement is completed, the first guide rod 19 is released, and the second elastic member 20 loses the force and returns to its original state, thereby pushing the first guide rod 19 to slide to the side close to the guide pipe 1101, so that the first guide rod 19 pushes the filter plate 17 to be inserted into the guide pipe 1101.

[0040] See also Fig.10 As shown, it also includes a second motor 21, a screw 22, a second guide rod 23 and a wiping block 24. The second motor 21 is installed on one side of the bottom of the diverter plate 9 by bolt connection. The output shaft of the second motor 21 is fixedly connected to the screw 22 through a coupling. The wiping block 24 is threadedly arranged on the screw 22. The wiping block 24 is made of sponge material, which is convenient for absorbing liquid and fitting closely to the inner wall of the mixing barrel 2 to achieve better cleaning effect. The second guide rod 23 is fixedly connected to the side of the bottom of the diverter plate 9 away from the second motor 21 by welding. The wiping block 24 is slidably connected to the second guide rod 23, and the wiping block 24 is driven by the motor to slide up and down along the second guide rod 23.

[0041] As the usage time increases, some tar and other impurities will remain on the inner wall of the mixing barrel 2. In order to remove the impurities on the inner wall of the mixing barrel 2, the second motor 21 is started to drive the screw 22 to rotate, so that the wiping block 24 slides up and down along the second guide rod 23. The wiping block 24 will wipe and scrape off the impurities and tar on the inner wall of the mixing barrel 2. Some impurities fall to the bottom of the mixing barrel 2 and will flow from the guide pipe 1101 to the filter plate 17 and be blocked.

[0042] See also Figure 1 and Fig.10 As shown, a protective cover 25 is slidably provided on the water inlet of the water storage tank 4, and a protective shell 26 is installed at the bottom of the diverter plate 9 by bolt connection, and the protective shell 26 is sleeved on the outside of the second motor 21. The protective cover 25 is used to block the opening of the water storage tank 4 when the device is not in use to prevent dust and other foreign matter from falling into the water storage tank 4, and the protective shell 26 is used to protect the second motor 21 to prevent the condensed water of the coke oven gas from rusting the second motor 21.
