1. A spiral nozzle coke quenching process is characterized in that: the process increases the pressure of water in the pipeline to 1.5 MPa through the action of the reducing pipeline and the spiral nozzles, the water is sprayed by rotary atomization through a spiral sheet device in the spiral nozzles, and 16 spiral nozzles are used for atomizing and quenching all scorched coke in a quenching carriage; under the effect of the pressure of water and atomized spraying, the red coke is isolated from air, water vapor permeates into a coke pile, the effect of uniform coke quenching is achieved, on the other hand, a coke block is contacted with water swallow vapor, the coke block is cooled uniformly in the coke quenching process, the phenomenon of rapid cooling and rapid heating is avoided, the bursting and cracking of the coke block are reduced, the generated coke powder is obviously reduced, and the coke block does not jump out of a car box instantly in the coke quenching process.

Technical Field

The invention relates to a spiral nozzle coke quenching process.

Background

At present, the formed coke produced in China is sintered and carbonized in a furnace kiln and then subjected to coke quenching treatment, and two modes of dry coke quenching and wet coke quenching are generally adopted. The dry method coke quenching needs special equipment, has high cost, large investment and long period, and is less in use; the wet coke quenching is to pour the burnt formed coke into a water pool directly for soaking and cooling, and although the mode has fast coke quenching and simple operation, the formed coke must be dried after cooling, so the working procedures are increased, and the time and the labor are wasted.

Disclosure of Invention

The invention provides the spiral nozzle coke quenching process which is simple in process, reduces environmental pollution and improves the environment in order to solve the problems.

The technical scheme of the invention is as follows: the process increases the pressure of water in the pipeline to 1.5 MPa through the action of the reducing pipeline and the spiral nozzles, the water is sprayed by rotary atomization through a spiral sheet device in the spiral nozzles, and 16 spiral nozzles are used for atomizing and quenching all scorched coke in a quenching carriage; under the effect of the pressure of water and atomized spraying, the red coke is isolated from air, water vapor permeates into a coke pile, the effect of uniform coke quenching is achieved, on the other hand, a coke block is contacted with water swallow vapor, the coke block is cooled uniformly in the coke quenching process, the phenomenon of rapid cooling and rapid heating is avoided, the bursting and cracking of the coke block are reduced, the generated coke powder is obviously reduced, and the coke block does not jump out of a car box instantly in the coke quenching process.

The invention has simple process, reduces environmental pollution and improves environment.
