Abstract

The invention discloses a compact stainless steel wire mesh cleaning method of a fluidized bed. The fluidized bed multilayer compact stainless steel wire mesh used by a desulfurization composite blowing system can be conveniently and rapidly cleaned. Two blind plates are used for clamping the fluidized bed in the middle, the edges of the blind plates are tightened by bolts, and the upper side blind plate is connected with an air inlet pipe in a welded mode; a water tank with a proper size is manufactured and clear water is injected; the fluidized bed is placed in the water tank for soaking, asmall amount of dilute hydrochloric acid ( with concentration of about 13%) is added, then compressed air is intermittently introduced from the air inlet pipe of the upper side blind plate, and a liquid flow is used for washing the compact stainless steel wire mesh of the fluidized bed, lime powder clamped in the multilayer compact stainless steel wire mesh is completely blown out after being dissolved.

Description

technical field

[0001] The invention relates to the field of molten iron desulfurization, in particular to the cleaning and dredging of multi-layer dense stainless steel nets used for spraying lime powder. Background technique

[0002] The shape of the fluidized bed is trumpet-shaped, and the side is uniformly pressed by multi-layer dense stainless steel mesh. The airflow passes through the dense stainless steel mesh from the outside and enters the inside of the cone evenly to fluidize the lime and magnesium powder in the fluidized bed, so that The gas can evenly transport lime and magnesium powder into the molten iron, avoiding the unstable flow of the powder and causing the molten iron to splash. If the dense stainless steel mesh is clogged and the air permeability is not good, it will affect the fluidization effect of lime and magnesium powder, the flow of gas conveying powder will be unstable, and molten iron will splash, resulting in metal loss and burning of vehicles. ...
