Three-dimensional water-cooled quenching car with single-way water supply at bottom and working method thereof

Abstract

The invention relates to a three-dimensional water-cooled quenching car with a single-way water supply at the bottom and a working method thereof. A front side plate, a rear side plate, and a bottom plate of the quenching car adopt a sandwich structure respectively, and vertical water flow channels in sandwich structures of the side plates are respectively communicated with the inner space of a car body through a side plate upper water inlet and a side plate lower water inlet; longitudinal water flow channels in the sandwich structure of the bottom plate are respectively communicated with theinner space of the car body through a bottom plate upper water inlet, a bottom plate middle water inlet, and a bottom plate lower water inlet. A water injection system comprises an upper water pipe, afirst main water pipe, a second main water pipe, a plurality of side plate first water distribution pipes, a plurality of side plate second water distribution pipes, and a bottom plate water distribution pipe; after being injected into each sandwich structure, the cooling water enters the quenching car through the plurality of water inlets distributed along the entire area from the side and the bottom, and a coke is directly cooled at different parts to increase a coke clearance; the cooling water in the sandwich structure also has an indirect cooling effect for the cake, and finally uniformcooling of the entire area of the coke is achieved, and an overall cooling efficiency of the coke is improved.

Description

technical field [0001] The invention relates to a coke quenching vehicle, in particular to a three-dimensional water-cooled coke quenching vehicle with single-way water supply at the bottom and a working method thereof. Background technique [0002] 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...

Problems solved by technology

[0009] However, because the above-mentioned technical solution is arranged in the coke pushing trailer, when the heavy coke falls, the central water channel is easily damaged by force.

In the long run, coke does not cool down very well

[0010] Insufficient red coke quenching in the coke quenching car leads to the direct consequences: red coke is still present, the belt of the coke drying table is easily burned after unloading, and the coke quality is not good. The indirect consequence is: the red coke is stored in the quenching car If the time is too long, the heat-resistant plate, frame, etc. of the barbecue quenching car will also prolong the quenching time. The quenching car is more likely to be deformed due to the long heating time, shortening its life
