Slag granulation steam recovering device

Abstract

The invention discloses a slag granulation steam recovering device, which comprises a steam exhaust chimney, wherein the bottom end of the steam exhaust chimney is provided with a water discharging structure; a steam guide pipe communicated with the inner cavity of the steam exhaust chimney is transversely above the bottom end face of the steam exhaust chimney; a horizontal flow guide pipe I is transversely arranged above the steam guide pipe; the outlet end of the horizontal flow guide pipe I is connected with a vertical flow guide pipe; a spray washing device is arranged in a pipe at the connected part of the horizontal flow guide pipe and the vertical flow guide pipe; the lower end of the vertical flow guide pipe is closed to form a water collecting pit; a horizontal flow guide pipe II is arranged above the water collecting pit; a front steam and water separator is arranged in the middle of the horizontal flow guide pipe II, and the outlet end of the horizontal flow guide pipe II is connected to a mixer; and a rear steam and water separator, a fan and a steam exhaust air cylinder are arranged in the mixer in turn from bottom up, an air inlet window is formed on the wall of the mixer below the rear steam and water separator. The structure of the slag granulation steam recovering device is reasonably designed, the matching effect is desirable and the separation effect is excellent.

Description

technical field [0001] The invention relates to the field of metallurgy, in particular to a device for recovering slag granulation steam. Background technique [0002] Metallurgical plants will produce a large amount of molten slag during the production process. Most of the molten slag is treated by water granulation. A large amount of steam will also be generated in the slag granulation project. The current steam treatment methods mainly include: The following 4 types: [0003] (1) Arbitrary discharge; (2) After collection, use the chimney to discharge; (3) After collection, use pipes to lead to the top of the blast furnace for discharge; (4) After collection, spray water to cool and recover steam, which is the environmental protection INBA method of PW Company. [0004] Relatively speaking, the first two methods have a great impact on the environment, and at the same time, the water loss is also large; although the third method reduces the impact on the environment, the c...
