Embodiment 1

[0040] This embodiment is the coke quenching of red coke that is cooled by water-gas reaction and combined with a pressurized water vaporization cooling tank that discharges upside down. The system is as follows figure 1shown. 950-1050°C red coke 1 and coke powder 2 (added by 1% of the weight of red coke) are simultaneously added to the red coke pre-storage section 3a in the water-gas reaction cooling tank 3 from the top, move from top to bottom in the tank, and Water gas reacts with water vapor 6a to generate water gas, and then it is discharged from water gas outlet 4 and sent to the coke oven for combustion as gas. The coke that has been cooled to about 700°C by the water gas reaction enters the spraying water vaporization steam production cooling tank 5 and slides downward, and transfers heat with the sprayed water vaporization production steam cooling water inlet 6, and the water vaporization produces water vapor 6a that moves upwards and enters the water gas reaction coo...

Embodiment 2

[0042] This example is a coke quenching scheme in which red coke is cooled by water gas reaction and combined with a fixed pressurized water vaporization cooling tank. The system is as follows figure 2 shown. The mixture 14 of red coke 1, anthracite and coke powder at 950-1050°C (10% by weight of red coke, wherein the coke powder and anthracite account for half each) is simultaneously added to the pre-stored section 3a in the water gas reaction cooling tank 3 from the top, It moves from top to bottom in the tank, and reacts with water vapor 6a to generate water gas, then discharges from water gas outlet 4 and sends it to the boiler for combustion as gas. The coke that has been cooled to about 720°C by the water gas reaction enters the sprinkling vaporization steam production cooling tank 5 and moves downward, and transfers heat with the sprayed water vaporization production steam cooling water inlet 6, and the water vaporization produces water vapor 6a and moves upward into t...

Embodiment 3

[0044] This embodiment is basically the same as Embodiment 1, the difference is that the pressurized water vaporization and cooling process is completed alternately by two parallel up and down pouring type pressurized water vaporization and cooling tanks, the system is as follows image 3 shown. Red coke and coke powder (added according to 6% of the weight of red coke) are imported into the water gas reaction cooling tank to cool down, and then the water is vaporized to produce steam to cool down, and then introduced into the pressurized water vaporization cooling tank 8A through the mobile coke chute, after reaching the predetermined coke quantity The mobile coke chute is transferred to the pressurized water vaporization cooling tank 8B to import coke; the pressurized water vaporization cooling tank 8A filled with coke is sealed (the process is as in embodiment 1) spraying water vaporization cooling, when the cooling tank 8B is full of coke , and after the coke cooling proces...

Abstract

The invention relates to a method and a device for quenching coke and recovering energy. The method at least comprises the following steps: (1) a water gas reaction temperature reducing process, that is, red coke pushed out from a coke oven generates chemical reaction with water vapor to generate water gas, and heat is absorbed through water gas reaction of generated water gas so that coke is cooled; and (2) a pressured water vaporization temperature reducing process, that is, coke cooled through water gas reaction is directly contacted with water in a closed container to generate vaporization of water so that coke is cooled and water vapor capable of being used as a gas-state heat source can be generated simultaneously. The water vaporization temperature reducing process is at least composed of a coke feeding process, a water vaporization temperature reducing tank closing process, a spray water vaporization process under condition of water volume control, a water vaporization temperature reducing tank decompression process and a coke discharging process. By utilizing the method and the device, heat can be recovered, pollution is not generated, investment is small, running cost is low, and coke quenching time is short. The invention provides the efficient and low-cost method and the device for quenching coke and recovering energy of coking industries.

Description

technical field [0001] The present invention relates to a method and device for cooling red coke and recovering energy in the coking industry, especially utilizing water vapor and red coke to produce water gas reaction to cool down, and directly contacting and vaporizing water and coke to produce steam that can be used as a heat source for recycling. The method and the device 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 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 the temperature. Although this method has simple equipment and fast coke quenching speed...
