Technical Field

The invention belongs to the technical field of metallurgy, and particularly relates to a cleaning device and a cleaning method for an acid gun nozzle of a cold rolling acid regeneration unit.

background

the spray roasting method is a main process for treating the pickling waste acid of the cold-rolled strip steel, and the waste acid after being discharged is subjected to silicon removal purification, spraying, roasting and absorption to produce regenerated acid with the concentration of 18% for a production line. Not only reduces the production cost of cold rolling, but also protects the environment by zero pollution emission; and simultaneously, a byproduct, namely iron oxide red, which can be used as a raw material for producing soft magnets is produced, and a new economic value is created. In the production process of the acid regeneration unit in the spray roasting process, the spraying and atomizing effects of the acid gun nozzle are particularly important, and the production stability of the acid regeneration unit is directly influenced, so that the concentration fluctuation of the regenerated acid and the quality reduction of the byproduct iron oxide red are caused.

The existing acid gun nozzle cleaning method is original manual cleaning, the cleaning effect cannot be guaranteed, the nozzle atomization effect can be detected only by installing a spray disc on an acid gun, if the atomization effect cannot meet the requirement, the spray disc needs to be detached again for secondary cleaning, the process requirement can be met only by repeatedly cleaning, and time and labor are wasted. The roasting furnace is used for supplying acid for a long time by two acid guns, so that the yield of a regeneration system is reduced, and the concentration of the regenerated acid fluctuates to influence the quality of the regenerated acid.
