Problems solved by technology

However, since the coke tank has to withstand repeated heating and cooling at short intervals from 1000°C to 200°C, the material becomes a big problem for the container that needs to withstand pressure; The airtight locking device that exerts pressure between the tanks requires high pressure, fast action, and easy control, so its structure and action mode are very important for the smooth and efficient operation of airtight coke quenching

Embodiment 1

[0037] This embodiment is a scheme of a closed vaporization coke quenching device, such as figure 1 shown. 5 seconds before the coke tank is loaded with red coke, water is sprayed on the outer wall of the coke tank through the water spray nozzle 2 to form a water film 3 to vaporize and cool the coke tank shell. After it is moved under the top airtight cover 6 in the coke quenching tower (not shown in the figure), it passes through the heat-shielding panel moving mechanism 20 ( Figure 6), remove the heat-shielding panels 19 from both sides of the coke tank, lower the top airtight cover 6, turn the rotatable turn plate 17 of the coke tank airtight locking mechanism around the rotation shaft 16 fixed on the outer edge of the top airtight cover, and turn the coke The outer edge 13 of the tank opening and the outer edge 22 of the top airtight cover are embedded therein, and the compression bolt 15 is driven by the rotation of the motor 18 (as image 3 shown), compress the press...

Embodiment 2

[0040] This embodiment is basically the same as Embodiment 1, except that the coke tank is composed of an inner liner, a heat insulation layer and a coke tank shell. And the airtight locking of the coke tank tube adopts the fastening bolt passing structure (such as Figure 8 and 9 shown), that is, the top airtight cover 6 is lowered, and the rotatable turn plate 17 of the coke tank airtight locking mechanism is rotated around the rotating shaft 16 fixed on the outer edge of the top airtight cover, and the outer edge 13 of the coke tank opening and the top airtight cover The outer edge 22 is embedded in it, and the through-type fastening bolt 29 enters the outer edge of the coke tank opening and the outer edge of the top airtight cover into the groove 30, and the motor 18 rotates to drive the through-type fastening bolt 29 to press the outer edge of the coke tank opening The through-type pressing plate 23 and the top airtight cover outer edge pass through the type pressing plat...

Embodiment 3

[0043] This embodiment is basically the same as Embodiment 1, except that the coke tank is composed of a single layer, and the upper part of the outer edge of the coke tank opening is a plane with an inclination angle β of 8°. During the coke quenching process, the coke tank also swings around the upper shaft (not shown in the figure), and when the angle between the bottom plane of the coke tank and the horizontal plane is 15°, it stays for 15-20 seconds. The water spray pipe 32 in the middle is connected to the water inlet 33 to quench the coke for 6 seconds, and the bottom water spray pipe 26 at the high position is connected to the water inlet 27 for 9 seconds to quench the coke; after that, the water spray is stopped, and the bottom of the coke tank faces the opposite direction. Swing until the angle between the bottom plane of the coke tank and the horizontal plane is 25°, stay for 15-20 seconds, and the bottom water spray pipe and the middle water spray pipe in the high p...

Abstract

The invention relates to a sealed vaporization quenching method and device in coking industry. According to the method, red coke is arranged in a coke pot; through a top sealing cover, water is sprayed into the pot in a sealed state, so that the temperature of the coke is lowered; in addition, steam is recovered and utilized; before the coke is arranged in the coke pot or in the coke filling process, the water is sprayed to the outer wall of the coke pot filled with the red coke to perform water vaporization cooling on the outer wall of the coke wall; when the temperature of the coke in the coke pot is lowered to be below 600 DEG C, the water spraying cooling on the outer wall of the coke pot stops. A coke filling opening is formed in the top of the coke pot, and is also used as a coke discharging opening at the same time; the coke pot realizes vertical pouring through a pot turning mechanism; the coke is arranged when the coke filling opening is in an upward state, and the coke is discharged out when the filling opening is in a downward state; the outer wall of the coke pot is provided with a water spray head for performing water vaporization cooling on the outer wall of the coke pot; an inlet of the water spray head is connected with a water pump outlet; the coke pot is made of metal iron as major metal materials. The device has the advantages that the pressure bearing and quick cooling and heating bearing capability is high; the equipment is simple; the operation is convenient.

Description

technical field [0001] The invention relates to a device for cooling down and recovering heat energy of red coke in the coking industry, especially a device for directly spraying water on red coke in a closed container to vaporize the coke to cool down the coke, generate steam for recycling and prevent pollutants from being discharged into the atmosphere, belonging to Energy and energy recovery and environmental protection. Background technique [0002] Coke is an important raw material in the iron and steel industry. The high-temperature coke (red coke) released from the coke oven needs to be cooled in a short time, that is, coke quenching. Red coke contains a lot of heat energy, if it can be recycled, it can save energy and reduce emissions at the same time. So far, the wet coke quenching method is mainly used in the open system to spray water to cool down. This method has simple equipment and fast coke quenching speed, but it loses a lot of heat energy carried by red cok...
