Low-moisture environment-friendly quenching car for small coke oven, and operation process thereof

Abstract

The invention discloses a low-moisture environment-friendly quenching car for a small coke oven, and an operation process thereof. The coke quenching car comprises a cart, a coke quenching box, a water tank, a water feeding pipe, an atomizing nozzle, a dust removal cover, a dust removal hose, a water feeding pipe connector, a water feeding valve, a water valve switch, a positioning rod, a water feeding pipe water inlet positioning part, a water feeding pipe hose, a water discharging pipe water inlet positioning part, a water discharging pipe hose, a steam outlet, a water discharging valve, a water discharging pipe connector, a water discharging pipe and a water discharging hole, and the coke quenching box and the water tank are arranged on the cart side by side. According to the low-moisture environment-friendly quenching car for the small coke oven, a top quenching and bottom quenching combined wet quenching mode is adopted, the top quenching water amount and the bottom quenching water amount can be independently and accurately adjusted, the coke moisture can be more stably controlled while the quenching time is shortened, and the situation that local moisture is too high is avoided. Steam generated in the coke quenching process is introduced into water for purification and dust removal, the environment is not polluted, and the occupational health of operators can be guaranteed.

Description

technical field [0001] The invention belongs to the technical field of coking equipment, and in particular relates to a low-moisture environmental protection coke quenching vehicle for small coke ovens and its operating process. Background technique [0002] With the enlargement of domestic blast furnaces, the quality requirements of blast furnace coke are gradually increasing. Contradictory to this is that the reserves of high-quality coke fat coal are decreasing year by year, which limits its proportion in blending coal. In this context, it is very important to study the compatibility of various coal types, optimize the coal blending structure, improve the coking performance of blended coal through the complementarity between various coal types, and improve the quality of coke. [0003] Most coking plants in China use 40kg experimental coke ovens to study coal blending schemes and guide production. The coke quenching methods include dry quenching and wet coke quenching. ...

AI Technical Summary

Problems solved by technology

Dry coke quenching is rarely used due to the relatively complex equipment and implementation cost much higher than wet coke quenching. At present, most laboratories still use the direct spray wet coke quenching method

However, direct spraying will lead to excessive moisture in the upper coke or red coke in the lower part during the coke quenching process, which will affect the implementation results

In addition, the toxic vapor produced during the coke quenching process not only pollutes the environment, but also threatens the health of operators
