Description

Technical Field

[0001] The utility model relates to the technical field of coal tar processing, in particular to a coal tar flash evaporation tower. Background Technique

[0002] Coal tar is a black or dark brown viscous liquid with a pungent odor produced during the carbonization of coal. Coal tar can be divided into low-temperature coal tar, medium-temperature coal tar and high-temperature coal tar according to the carbonization temperature. The coal tar obtained in coke production belongs to high-temperature coal tar. It is one of the purified products of coke oven gas condensed and separated during the cooling process of crude gas. Coal tar is generally used as a raw material for processing and refining to produce various chemical products, or can be directly used, such as as an ingredient in the binder for industrial briquettes, shaped coke and coal-based activated carbon, and can also be used as fuel oil, blast furnace injection fuel, wood preservative and raw material for making carbon black.

[0003] In the existing coal tar flash evaporation towers, most of them are manually cleaned by workers. During the cleaning process, it is easy to inhale the harmful gases generated by coal tar processing, causing damage to the body. In addition, most of the water vapor generated during processing is directly discharged into the air and cannot be recycled, and the harmful substances inside are likely to cause air pollution.

A fan 3 is arranged on one side of the telescopic motor 2, an air delivery pipe 4 is arranged on one side of the fan 3, a delivery pipe 5 is arranged on one side of the air delivery pipe 4, a cooling tank 6 is arranged at the bottom of the delivery pipe 5 to cool and condense the water vapor generated by flash evaporation, and avoid pollution caused by carrying poisonous gas when directly discharged into the air. A shunt pipe 7 is arranged at the top of the cooling tank 6, a delivery hose 8 is arranged at the top of the shunt pipe 7, the outer wall of the cooling tank 6 is movably connected with a first fixing ring 9, a water outlet 10 is arranged on the outer wall of the cooling tank 6, a return pipe 11 is arranged at the bottom of the cooling tank 6 to make the cooling cold water circulate and disperse the heat. A water storage tank 12 is arranged at the bottom of the return pipe 11. The outer wall of the first fixing ring 9 is movably connected with a docking rod 13, one side of the docking rod 13 is movably connected with a second fixing ring 14. A feed inlet 15 is arranged on the outer wall of the tower body 1, a blanking port 16 is arranged at the bottom of the feed inlet 15. A mounting plate 17 is arranged at the bottom of the telescopic motor 2, a submersible motor 18 is movably connected to the bottom of the mounting plate 17 to control the cleaning brush 21 to rotate and clean the flash evaporation chamber 22. A rotating shaft 19 is arranged at the bottom of the submersible motor 18, a bracket 20 is movably connected to the outer wall of the rotating shaft 19, and a cleaning brush 21 is arranged on one side of the bracket 20. A flash evaporation chamber 22 is arranged inside the tower body 1. A cooling pipe 23 is arranged at the bottom of the shunt pipe 7, a water collecting pipe 24 is arranged at the bottom of the cooling pipe 23, and an inner cavity 25 is arranged inside the cooling tank 6.

[0018] Wherein, a water inlet pipe is arranged at the top of the water storage tank 12, a drain pipe is arranged at the back of the water storage tank 12, and valves are arranged on the outer walls of the drain pipe, the water outlet 10, and the blanking port 16.

[0019] Among them, the first fixing ring 9 has a semi-circular ring shape in its external features. Two groups of the first fixing rings 9 form a set of limiting rings, and the number of sets of limiting rings is three in each case, which fixes the positions of the water storage tank 12 and the cooling tank 6.

[0020] Among them, a docking rod 13 is provided between the first fixing ring 9 and the second fixing ring 14. The docking rod 13 is fixedly connected to the first fixing ring 9 and the second fixing ring 14 by bolts, and the docking rod 13 is detachable.

[0021] Among them, the telescopic motor 2, the mounting plate 17, the submersible motor 18, the rotating shaft 19, the bracket 20, and the cleaning brush 21 form a cleaning structure. A telescopic rod is provided between the telescopic motor 2 and the mounting plate 17 to clean the inside of the flash evaporation chamber 22, reducing the burden on staff for manual cleaning and preventing internal toxic gas from entering the body and causing harm.

[0022] Among them, a water pump is provided inside the water storage tank 12, and a delivery hose 8 is provided on one side of the water pump.

[0023] Specifically, during use, the tar kerosene to be processed is put into the flash evaporation chamber 22 inside the tower body 1 from the feed inlet 15. Then, the tar kerosene reacts through high temperature in the flash evaporation chamber 22. The water vapor generated by the reaction moves upward and is attracted by the gas blown by the fan 3 and quickly enters the delivery pipe 5, and is blown by the wind into the cooling tank 6. When contacting the internal cooling pipe 23, affected by the low temperature, it quickly condenses into water and accumulates in the inner cavity 25. To prevent the temperature of the cooling water inside the cooling pipe 23 from rising, the cooling water circulates successively along the water storage tank 12, the delivery hose 8, the shunt pipe 7, the cooling pipe 23, the water collecting pipe 24, and the return pipe 11 to achieve the effect of cooling the cooling water. The cooling water flowing back into the water storage tank 12 is re-injected into the delivery hose 8 by the water pump for re-circulation. After there is no more water vapor, the valve on the outer wall of the water outlet 10 is opened to utilize the water source inside the cooling tank 6. When the flash evaporation in the flash evaporation chamber 22 is completed, the valve on the outer wall of the discharge port 16 is opened to recycle it. When it is necessary to clean the inside of the flash evaporation chamber 22, clean water and cleaning liquid are put in from the feed inlet 15. Then, the telescopic motor 2 controls the telescopic rod to move downward. While moving, the submersible motor 18 controls the rotating shaft 19 to rotate, so that the cleaning brush 21 cleans the inner wall of the flash evaporation chamber 22. After cleaning, the sewage is discharged from the discharge port 16.
