Description

Technical Field

[0001] This patent relates to the field of waste heat recovery technology, specifically a waste heat recovery and utilization device for a wet quenching system. Background Art

[0002] In the coking process, the high-temperature coke coming out of the coke oven needs to go through a series of treatments such as quenching, cooling, screening, and storage. Wet quenching is often used. Wet quenching is to use a quenching car to carry the red coke out of the oven to the quenching tower, and spray a large amount of water on the red coke just out of the oven, so as to achieve the purpose of quenching the coke. During wet quenching, the temperature of the coke pushed out of the coke oven reaches about 1000℃. After being cooled to about 150℃ by water spraying, it is cooled. In the process of quenching, the water is heated and vaporized to produce a large amount of steam. Direct discharge will undoubtedly cause energy waste and loss, and will also cause pollution to the environment.

[0003] The so-called waste heat is high-temperature steam. The waste of high-temperature steam is the waste of water resources. The existing water recovery is to liquefy the high-temperature steam into water by contacting the high-temperature steam with water mist. However, the high-temperature steam moves too fast into the recovery box, which makes it easy for the high-temperature steam to not completely contact with the water mist, resulting in poor water recovery efficiency. For this reason, we propose a waste heat recovery and utilization device for the wet quenching system. Utility Model Content

This patent installs multiple mesh bodies on the inner wall of the recovery box, which can slow down the upward movement speed of the high-temperature steam. At the same time, a baffle that can move left and right is provided in the side wall of the steam spray hood. The baffle can be used to adjust the internal path size of the steam spray hood, thereby reducing the circulation speed of the high-temperature steam, facilitating the high-temperature steam to fully contact with the water mist, and ensuring the recovery efficiency.

It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. In addition, it should be understood that after reading the contents of the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the claims attached to the application.

[0018] See also Figure 1 and Figure 2 This is a schematic diagram of the structure of the patent, a waste heat recovery and utilization device of a wet quenching system, including a recovery box 1, an injection pipe 2 is embedded in the left wall of the recovery box 1, a steam pipe 3 is fixedly installed at the right end of the injection pipe 2, and a steam spray hood 4 is fixedly connected to the right end of the steam pipe 3, a water pipe 5 is embedded in the middle of the top of the recovery box 1, and a water collecting pan 6 is fixedly connected to the bottom of the water collecting pan 6, and an atomizing nozzle 7 is embedded at the bottom of the water collecting pan 6, and a mesh body 8 is fixedly installed on the inner wall of the recovery box 1, and the number of the mesh bodies 8 is four;

[0019] like Figure 1 As shown, there is a certain distance between the multiple mesh bodies 8, and the positions of the holes on the multiple mesh bodies 8 can be staggered, thereby increasing the upward movement path of the steam.

[0020] A through opening 9 is provided at the right end of the side wall of the steam spray hood 4, and a baffle 10 is slidably installed on the inner wall of the through opening 9. An internal threaded tube 11 is fixedly installed on the right end of the outer wall of the steam spray hood 4. A screw 12 is screwed to the inner wall of the internal threaded tube 11, and a circular plate 13 is integrally formed at the right end of the screw 12. An annular groove 14 is provided on the side wall of the circular plate 13, and a circular ring 15 is rotatably installed in the annular groove 14. The bottom right end of the baffle 10 is fixedly installed on the top of the outer wall of the circular ring 15.

[0021] The circular plate 13 and the circular ring 15 can rotate relative to each other.

[0022] Figure 2 The circular plate 13 can be rotated and moved to the left. The circular plate 13 drives the ring 15 and the baffle 10 to move to the left through the annular groove 14, thereby changing the internal size of the steam spray hood 4, reducing the amount of high-temperature steam sprayed from the steam spray hood 4, and indirectly reducing the amount of steam flowing upward, which helps the steam to fully contact with the water mist.

[0023] Specifically, a water outlet 16 is provided on the right side of the bottom of the side wall of the steam pipe 3 , and the steam pipe 3 is located at the lower side of the steam spray hood 4 .

[0024] The water outlet 16 facilitates the falling of water.

[0025] Specifically, a first inclined surface 17 is provided at the bottom end of the inner wall of the steam pipe 3 , and the lowest end of the first inclined surface 17 faces the water outlet 16 .

[0026] The first inclined surface 17 can prevent water from flowing back into the left side of the steam pipe 3 .

[0027] Specifically, it also includes a collection box 18 . A drainage pipe 19 is embedded at the bottom of the right side wall of the recovery box 1 , and the right end of the drainage pipe 19 is plugged into the collection box 18 .

[0028] The collection box 18 is provided to facilitate the collection of the recycled water.

[0029] Specifically, a water pump 20 is installed on the top of the collection box 18, the input end of the water pump 20 is connected to a water inlet pipe 21, the water inlet pipe 21 is inserted into the collection box 18, the output end of the water pump 20 is connected to one end of a water outlet pipe 22, and the other end of the water outlet pipe 22 is connected to the water pipe 5.

[0030] The recovered water can be pumped out by the water pump 20 and converted into water mist through the atomizing nozzle 7, which is conducive to recycling.

[0031] Specifically, the inner bottom wall of the recovery box 1 is provided with a second inclined surface 23 .

[0032] The second inclined surface 23 is provided to facilitate water to enter the drain pipe 19 .

[0033] Working principle: The injection pipe 2 sprays the high-temperature steam generated by wet quenching through the steam spray hood 4. The water mist sprayed by the atomizing nozzle 7 contacts with the high-temperature steam to liquefy the high-temperature steam into water. The upward movement speed of the high-temperature steam can be slowed down by a plurality of mesh bodies 8. At the same time, a baffle 10 that can be moved left and right is provided in the side wall of the steam spray hood 4. The internal path size of the steam spray hood 4 can be adjusted by the baffle 10, thereby reducing the circulation speed of the high-temperature steam, making it easier for the high-temperature steam to fully contact with the water mist and ensure the recovery efficiency.
