As shown in FIGS. 1 to 3, the present invention relates to a vertical steel slag hot-pressing treatment method, preferably the hot-pressing method using the hot-pressing tank, comprising the following steps:
(1) feeding the solid steel slag into a hot stuffy tank; after the molten liquid steel slag is cooled, solidified and crushed into solid hot steel slag with the temperature of about 300-500 ℃ and the granularity of less than 300mm, the solid hot steel slag preferably enters a slag tank through a chute to be hot stuffy and loaded with slag, the slag tank is lifted into a tank body of a large-diameter vertical steel slag with a hot-pressing stuffy tank by a crane, the slag tank is placed on a slag tank support 15 through a guide device 14 in the tank body, then a tank cover is locked between the tank cover and the tank body through a turning oil cylinder of a tank cover turning device 3 and a lifting oil cylinder 38 of a tank
(2) hot pressing and smoldering; after the tank cover and the tank body are locked and sealed, the water spraying device 9 starts to spray water and cool, pressurized saturated steam is formed in the tank body and permeates into the steel slag through gaps, and the steel slag is reacted and expanded with unstable substances contained in the steel slag, preferably free calcium oxide, so that the stabilization treatment of the steel slag is realized, the separation constant-pressure control between iron and slag is completed, in the process of pressure heating and stuffiness, the pressure and the temperature of the saturated steam in the tank body are monitored in real time through the safety monitoring device 13, the combustible gas components and the concentration value in the tank body are also monitored in real time, on one hand, the steam in the tank body is ensured to reach the required pressure through gas leakage of the sealing device, on the other hand, the exhaust pressure stabilizing device 12 is controlled to;
(3) gas replacement; when hot stewing is finished, the concentration value of combustible gas generated in the hot stewing process of the steel slag in the tank body is not in a safe range, in order to ensure the slag discharging safety, the gas replacement device 16 introduces inert gas into the tank body when the hot stewing is finished, the combustible gas is extruded out through the exhaust pressure stabilizing device 12, and finally the safe replacement is realized;
(4) deslagging; before the tank cover is unlocked and opened, the exhaust pressure stabilizing device 12 is opened, gas in the sealing device is discharged, and the tank cover can be opened until the pressure in the tank body is zero, so that the slag tank containing the processed steel slag is lifted out by a travelling crane.
Preferably, the pressure hot-disintegrating treatment method comprises the steps of hoisting a slag tank filled with the steel slag with a certain temperature of about 300-500 ℃ into a slag tank support in the steel slag pressure hot-disintegrating tank, closing a tank cover through a turning oil cylinder, a lifting oil cylinder and a rotating oil cylinder, locking and sealing, spraying hot slag to the steel slag in the tank body by a water spraying device at the top of the tank cover, rapidly cooling the surface layer when the hot slag meets water, enabling the surface layer of the steel slag to be disintegrated and generate cracks due to stress generated by temperature difference, enabling a large amount of low-pressure steam generated after the waste heat of the steel slag heats water to quickly cover the surface of the steel slag and permeate into the cracks, rapidly reacting with a free state in the slag, changing the organization structure, reducing the specific gravity, generating expansion due to the increase of the volume of the steel slag. Because the reaction process is carried out in a closed pressure container, the water vapor formed after water spraying is not discharged outside, and a certain pressure and temperature atmosphere is formed in the tank, under the action of the pressure, the steam can penetrate into the interior of the massive steel slag through the fine cracks to react instead of only staying on the surface of the steel slag, the reaction speed is improved, and the slag blocks are further rapidly cracked and pulverized.
