Quenching car adopting single-way water supply and bottom water cooling and working method of quenching car

Abstract

The invention relates to a quenching car adopting single-way water supply and bottom water cooling and a working method of the quenching car. A body of the quenching car has a compartment structure formed by two side plates, a front end plate, a rear end plate and a bottom plate, and the bottom plate is inclined; a turning plate is arranged at the lower part of the rear end plate, and drain portsare formed in the side plates; the bottom plate is provided with a sandwich structure, and multiple longitudinal water channels are formed by transverse ribs and longitudinal bars in the sandwich structure; a water injection system comprises water feeding pipes, a main water pipe and multiple branch water pipes, the branch water pipes are communicated with the water channels in a one-to-one corresponding manner; an upper water inlet, a middle water inlet and a lower water inlet are formed in the top surface of each longitudinal water channel in the longitudinal direction of the body. Cooling water of the water injection system enters the quenching car through the multiple water inlets in the top of the sandwich structure and directly cools the bottom of a coke layer in different positions,meanwhile, water in the sandwich structure indirectly cools the bottom of the coke layer, finally, full-area uniform cooling of the bottom of the coke layer is realized, and overall cooling efficiency of the coke layer is improved.

Description

technical field The invention relates to a coke quenching car, in particular to a water-cooled coke quenching car with single-way water supply and direct and indirect cooling of the entire bottom of the coke layer. Background technique The temperature of mature hot red coke is about 950°C-1100°C. The self-pushing machine pushes the hot red coke out of the coke oven hole and transports it to the quenching equipment. Usually, a quenching car is used to carry the red coke. . According to the different coke quenching methods, the coke quenching vehicles used for dry coke quenching and wet coke quenching are also different. The upper part of the wet coke quenching vehicle is usually a square section, and the lower part is slope-shaped to facilitate coke discharge. The coke quenching process is usually sprayed with cooling water from above the coke layer. However, because the thickness of the coke layer is relatively thick and the red coke gaps are not enough, the cooling effec...
