Embodiment 1

[0043] This embodiment is a coke quenching process scheme for red coke by spraying water in a closed chamber to vaporize and cool down. The red coke pushed out from the coking chamber of the coke oven is loaded into the coke transport tank 1 and then pushed by the coke transport power vehicle 2 through the transport vehicle 3 to move it to the coke quenching tank 5 through the coke transport track 4 . Carrier wheel 15 enters inclined track 6 (as figure 1 As shown), the inclination formed enables the coke transport tank 1 to enter the quenching tank 5 along the tank inner track 8 through the coke transport tank roller 7 . Afterwards, the tank cover 9 is rotated to make the tank cover flange 16 contact with the coke quenching tank inlet and outlet flange 17, and the airtight cover is locked by the tank cover locking mechanism 10 (such as figure 2 shown), and inflate and pressurize the sealing ring to achieve sealing, so as to achieve the purpose of isolating from the atmospher...

Embodiment 2

[0049] This embodiment is basically the same as Embodiment 1, except that the bottom of the coke transporting trough is provided with two parallel tracks (the coke transporting trough track 26) along the length direction, and the upper part of the carrier is provided with a turning roller (the turning roller 25 on the carrier car). ), correspondingly in the coke quenching tank is also provided with a turning roller (bottom turning roller 24 in the tank), the coke transport groove enters the coke quenching tank through the track at the bottom, turning the roller above the carrier vehicle and turning the stick track at the bottom of the coke quenching tank 5 and withdraw from the quenching tank, such as Figure 7 shown.

[0050] The locking mechanism of the quenching tank cover adopts the method of rotating the tank cover after the tank cover is inserted into the space between the flange teeth of the quenching tank entrance and exit, such as Figure 8 . The inlet and outlet fl...

Embodiment 3

[0053] This embodiment is basically the same as Embodiment 1, the difference is that the inlet and outlet flange of the quenching tank is a single-layer rack structure, the tank cover is a double-layer structure, and the tank cover is locked by moving the tank cover to move the quenching tank. The rack is embedded in the rack space of the tank cover, and rotated so that the rack of the tank cover overlaps with the rack at the entrance and exit flange of the quenching tank, so as to achieve the purpose of locking the entrance and exit flange of the quenching tank and its cover flange. The sealing ring is arranged on the lid of the coke quenching tank.

Abstract

The invention relates to a method and device for quenching red coke in coking industry. According to the method, a coke conveying tank is integrally and directly put into a closed container, water isdirectly sprayed for evaporation so as to cool the red coke, steam is recycled, a quenching tank and a tank cover capable of being rotatably opened and closed are closed by virtue of a flange, a sealing ring and a locking mechanism, and then quenching is realized in an atmosphere insulation state; the coke conveying tank is integrally and directly put into the closed container, so that the combustion loss of the red coke dispersively mounted in the quenching tank, the coke charging and discharging equipment, the coke charging and discharging difficulties, the lifting height of the red coke andthe equipment investment of a coke tank arranged underground are avoided, the problems that the diameter of the quenching tank is large and the quenching vehicle wheels are corroded when a traditional quenching vehicle enters the closed quenching tank are overcome, and conditions are created for the decrease of the investment of quenching equipment and the increase of the operation stability; thecoke conveying tank obliquely enters or exits the closed quenching tank, so that the simple power and the rapid operation of a traction mechanism are realized; the uniform quenching is realized by virtue of simple water spraying equipment and operation; and the heat energy can be recycled, the investment is small, and the quenching time is short.

Description

technical field [0001] The invention relates to a device and method for cooling red coke and energy recovery in the coking industry, in particular to a device and method for directly spraying water to vaporize red coke in a closed container to cool down the coke, generate steam for recycling and prevent pollutants from being discharged into the atmosphere The invention relates to a method and a method, which belong to the field of energy, energy recycling 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 coking chamber of the coke oven needs to be cooled rapidly in a short period of 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 ha...
