Problems solved by technology

[0002] At present, the coke quenching methods used in coking plants include water coke quenching and gas dry coke quenching. Water coke quenching is an ancient coke quenching method. The coke quenching material is water. Its advantage is that the construction cost is low, about 10 yuan / t coke , can add chemical substances to improve thermal performance in water, the disadvantage is that a large amount of steam containing phenol, benzene, cyanide, sulfide and dust will be thrown into the sky, polluting the environment and wasting energy; gas CDQ is a new The advanced coke quenching method developed, the coke quenching material is non-oxidizing gas such as nitrogen, its advantage is that it can use the energy of red coke and no pollutants are discharged into the atmosphere, its disadvantage is that the construction cost is high, about 200 yuan / t coke, equipment Complex, frequent and difficult maintenance, high operating costs

Embodiment 1

[0007] Example 1: Use 200-mesh graphite powder with 5 times the weight of red coke as the quenching powder, pour red coke and graphite powder into an inclined and rotatable cylindrical container while rolling down, and finally from the lower end of the cylindrical container Fall into the sieving equipment and sieve.

Embodiment 2

[0008] Embodiment 2: Add 200 mesh graphite powder with 4 times the weight of coke and 200 mesh quartz powder with 1 times the weight of coke as coke quenching powder, and use an upright cylindrical container with a screen and a door at the lower end as the coke quenching container. Pour red coke and quenching powder into the coke quenching container. After the coke quenching powder covers the coke, open the door to let the quenching powder fall, add quenching powder to cool down at the same time, and vibrate when the temperature of the coke drops below 200°C Separate and pour out.
