Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of coke quenching equipment, in particular to a corrosion-resistant coke quenching car of a wet coke quenching system. Background Art
[0002] The quenching car is a device used in conjunction with a large coke oven. Its function is to receive the coke at about 1000°C pushed out of the coke oven, then transport the coke to the quenching tower to spray quenching water to quench the coke, and finally transport the quenched coke to the coke drying platform. At present, the quenching cars used in large coking plants have longer and larger carriages, and the carriage loading capacity is also relatively large. Such large quenching cars have the following problems in actual use: ① Due to the large carriage capacity, the thickness of the coke layer after the coke is accumulated is thick. When quenching the coke by spraying quenching water, the top coke is often completely extinguished, while the bottom coke is not completely extinguished. If the coke is to be extinguished completely, it will take a long time. Long-term spraying will not only increase the moisture content of the top coke, affecting the quality of the top coke, but also prolong the time the carriage is baked by high-temperature red coke, causing damage. 1. Damage to the quenching car compartment, reducing the service life of the quenching car; 2. When the high-temperature red coke pushed out of the coke oven is pushed into the quenching car compartment, the probability and impact force of the front side wall and door of the quenching car being scoured by the red coke are the greatest due to the inclined bottom wall of the quenching car compartment. After the quenching car has been used for a period of time, the front side wall and door of the quenching car are seriously deformed; 3. Due to the long quenching car compartment, the front side wall and door of the quenching car are also long. After being subjected to the impact force of the red coke for a long time, the front side wall and door of the quenching car are easily deformed and damaged, affecting the overall service life of the compartment, thereby increasing the production cost of the enterprise. Therefore, it is an objective need to develop a corrosion-resistant quenching car with high quenching efficiency, thorough quenching and long service life. Utility Model Content

DETAILED DESCRIPTION
[0012] The present invention will be further described below in conjunction with the accompanying drawings, but the present invention is not limited in any way. Any changes or improvements made based on the teachings of the present invention shall fall within the scope of protection of the present invention.

A middle wall 8 is detachably connected between the front side wall 5, the rear side wall 7 and the compartment bottom wall 4, and when the middle wall 8 is damaged, it is convenient to replace the middle wall 8. The middle wall 8 divides the compartment into two left and right compartments, and the middle wall not only supports and pulls the front side wall, the rear side wall and the compartment bottom wall, reduces the deformation of the front side wall, the rear side wall and the compartment bottom wall, but also blocks part of the impact force of the red coke on the front side wall and the door. The partition walls 8 are all hollow structures. The tops of the front side walls 5, the rear side walls 7 and the middle wall 8 are all provided with lower water injection ports 11, and the upper outer wall of the door 6 is provided with side water injection ports 12. The front side walls 5, the door 6 and the rear side walls 7 are all provided with side wall water spray ports 13 for spraying water into the car, and the middle wall 8 is provided with middle wall water spray ports 14 for spraying water into the left and right cars respectively. When the quenching car moves under the quenching tower for spray quenching, part of the quenching water is sprayed into the car from the top of the car through the spray system, and part of the quenching water is injected into the cavities of the front side walls 5, the door 6, the rear side walls 7 and the middle wall 8 through the water injection heads cooperating with the lower water injection ports 11 and the side water injection ports 12. Under the action of water pressure, the quenching water in the cavity is sprayed out from the side wall water spray ports 13 and the middle wall water spray ports 14 to spray quench the red coke.
[0014] When the quenching car is in use, the corrosion-resistant quenching car of the wet quenching system of the present invention is first moved under the coke oven, and the high-temperature red coke pushed out by the coke oven falls into the car from the open top of the quenching car. After the coke is discharged, the quenching car transports the red coke along the driving track to the bottom of the coke quenching tower for spray quenching. Part of the quenching water is sprayed into the car from the top of the car through the spray system, and part of the quenching water is injected into the cavities of the front side wall 5, the car door 6, the rear side wall 7 and the middle wall 8 through the water injection head matched with the lower water injection port 11 and the side water injection port 12. Under the action of water pressure, the quenching water in the cavity is sprayed out from the side wall water injection port 13 and the middle wall water injection port 14 to spray quench the red coke. After the quenching is completed, the quenching car continues to transport the coke to the coke drying platform along the driving track.
