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

Embodiment 1

[0025] A low-moisture environment-friendly quenching car for small coke ovens, such as figure 1 As shown, it includes cart 1, coke quenching box 2, water tank 3, water supply pipe 4, atomizing nozzle 5, dust removal cover 6, dust removal hose 7, water supply pipe connection 8, water supply valve 9, water valve switch 10, positioning Rod 11, upper water pipe inlet location 12, upper water pipe hose 13, lower water pipe inlet location 14, lower water pipe hose 15, steam outlet 16, lower water valve 17, lower water pipe interface 18, lower water pipe 19, water outlet hole 20, The coke quenching box 2 and the water tank 3 are arranged side by side on the trolley 1;

[0026] The coke quenching box 2 is a box structure with an upper opening; the upper water pipe 4 is arranged on the top side of the coke quenching box 2 box body, and a plurality of atomizing nozzles 5 are arranged below the body of the upper water pipe 4; One end of the upper water pipe interface 8 extends into the ...

Embodiment 2

[0039] Based on the operation process of the low-moisture environmental protection coke quenching car for small coke ovens described in Example 1, the specific steps are as follows:

[0040] (1) Before connecting the red coke, adjust the water inlet positioning height of the upper water pipe to 10cm below the liquid surface, and adjust the water inlet positioning height of the lower water pipe to 12cm below the liquid surface.

[0041] (2) Put 1000°C red coke into the coke quenching box, cover it with a dust cover, open the upper water valve and the lower water valve at the same time through the water valve switch, and the coke quenching water in the water tank relies on gravity to pass through the upper and lower water pipes, hoses and The atomizing nozzle and water outlet are sprayed on the hot coke, and the steam generated passes through the dust cover, rubber hose and positioning rod, and is discharged into the water tank through the steam outlet for purification.

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. ...
