Description

Technical Field

[0001] The utility model belongs to the technical field of design and manufacturing of zinc-making rotary kilns, and in particular relates to a fixed recovery structure of a zinc-making rotary kiln. Background Art

[0002] There are two main methods for producing zinc: pyrometallurgical zinc production and hydrometallurgical zinc production. In pyrometallurgical zinc production, a rotary kiln is needed to smelt zinc materials so that zinc can be continuously reduced from the raw materials and volatilized in gaseous form through the high temperature of 1000°C in the kiln. The slag after the zinc volatilizes needs to be cooled in a cooling pool. When the high-temperature slag enters the cooling pool and comes into contact with water, a large amount of water vapor mixed with particulate matter will be generated. Once these water vapors enter the air, they will not only pollute the environment, but also cause waste of particulate matter because they cannot be recycled.

[0003] The patent document with the announcement number "CN 207751352 U3" records "a device for recovering water vapor and particulate matter from a zinc rotary kiln, comprising a rotary kiln with a discharge port, and a cooling water pool arranged below the discharge port of the rotary kiln, characterized in that a dust cover is arranged above the discharge port of the rotary kiln and the cooling water pool, the top of the dust cover is connected to the inlet end of a water vapor recovery pipe, the outlet end of the water vapor recovery pipe returns to the top of the rotary kiln discharge port, and a fan is arranged on the water vapor recovery pipe."

[0004] Although the above technical solution can recover the particulate matter mixed in the water vapor, it is not convenient to fix the rotary kiln during the actual use of the above technical solution. Therefore, the fixing of the rotary kiln during use is extremely cumbersome and unstable. Utility Model Content
