Dust suppression method after iron ladle mixed with iron and iron ladle mixed iron dust suppression device

Abstract

This application relates to the technical field of iron and steel production, in particular, it relates to a method for suppressing dust after iron ladle mixing and an iron ladle dust suppression device. The dust suppression method includes: arranging multiple fog along the return path after iron ladle mixing atomizing nozzles, so that the multiple atomizing nozzles are located above the iron ladle, each atomizing nozzle is connected to the water supply pipeline and the air supply pipeline, and an on-off switch is set on each atomizing nozzle; The opening and closing switches of each atomizing nozzle are all connected to the spray controller, and the spraying controller controls the opening and closing switches of the plurality of atomizing nozzles according to the return speed of the iron ladle and the initial return time to open sequentially according to the set interval time, Each atomizing nozzle closes after a set duration. The dust suppression method provided by this application after iron ladle is mixed with iron is a dynamic dust suppression method, which can set a longer dust suppression time, and the iron ladle turnover speed is fast, taking into account higher dust suppression safety, better dust suppression effect and higher production efficiency.

Description

technical field [0001] The application relates to the technical field of iron and steel production, in particular to a method for suppressing dust after mixing iron with iron and a dust suppression device for mixing iron with iron. Background technique [0002] In iron and steel metallurgical production, after the iron ladle is mixed with iron in the converter, a large amount of dust will overflow from the mouth of the iron ladle. Afterwards, after the nozzles are sprayed to reduce dust, the crane will transport away the iron ladle. The current treatment method needs to be careful of water leakage in the nozzle and its water pipe, and the large amount of water leakage may easily lead to safety accidents in the converter. However, due to the high temperature in front of the fire damper, it needs to be inspected and repaired during the production interval, so there is a great potential safety hazard. Contents of the invention [0003] The present application aims to provid...
