A coke quenching device

Abstract

The invention provides a coke quenching device. The device is used for cooling high-temperature semi-coke, and comprises a converter, wherein a feed port is formed in one edge side of the converter; the center of the converter is a converter outlet; the semi-coke is fed into the converter from the feed port, is cooled, and then is discharged from the converter from the converter outlet; a plurality of reverse flow guide devices for overturning the semi-coke and a plurality of directional flow guide devices for pushing the semi-coke to the center of the converter are arranged in the converter; a temperature measuring device is arranged on each of the directional flow guide devices and the reverse flow guide devices, and is used for measuring the temperature of the semi-coke passing through the temperature measuring device. The temperature measuring device is arranged in the coke quenching device, and can be used for measuring the cooling degree of the semi-coke in the coke quenching device in real time so as to further control the spray water quantity and prevent the excessive or insufficient quantity of spray water.

Description

technical field [0001] The invention relates to a coke quenching device, in particular to a coke quenching device capable of measuring the temperature of blue coke in a converter. Background technique [0002] Lignite is the mineral coal with the lowest degree of coalification, with a moisture content as high as 30% to 50% (10% to 30% after air drying), rich in volatile matter (up to 40%) and free humic acid, and is easy to weather and fragment. Low ignition point, easy to spontaneous combustion. Direct use, use value is not high. However, the world's lignite resources account for about 1 / 3 of the world's total coal resources. my country's lignite resources are 319.438 billion tons, and the proven reserves are 129.132 billion tons, accounting for more than 1 / 8 of the country's total coal reserves. Lignite is mainly distributed in eastern Inner Mongolia and eastern Yunnan, and a small amount is distributed in northeast and southern China. Lignite is not suitable for long-t...

AI Technical Summary

Problems solved by technology

[0005] 1. Do not recycle the spray water, rely on the spray water cooling and dust removal system, because there is no effective monitoring method, it is easy to cause excessive and insufficient spraying, and it is impossible to achieve precise control of the spraying water volume;

[0006] 2. No grouping control is adopted for the nozzles, and the spraying water volume and the temperature during the product cooling process cannot be well controlled;

[0007] 3. Use the spray water to hit other objects, and the fine water mist formed by the rebound can not be ignored while increasing the contact area between the water mist and the object to be cooled, and the damage to the impacting object cannot be ignored, and the size of the water mist and water droplets in the local area is uneven. Affects the overall cooling effect
