Abstract

The invention discloses a system for handling splashing of a converter. The system comprises a detection mechanism, a controller and an actuating mechanism, wherein the detection mechanism is mountedin a converter mouth or a flue gas channel, measures the concentration of dust or the speed of flue gas and transmits measuring results to the controller; the controller judges that the converter accidentally splashes after the concentration of dust or the speed of flue gas reaches a set value; at the moment, the controller controls the actuating mechanism to act; and the actuating mechanism comprises a plurality of booster pumps mounted in a dust control unit. According to the system for handling splashing of the converter, the dust content in flue gas of the converter or the flue gas speed are detected by the detection mechanism in real time; when the converter splashes and the flue gas amount and the dust amount are severely increased, the water spray amount of local parts in the dust control unit is increased rapidly; the dust control capability of the whole dust control unit is adaptively improved; flue gas and dust which are produced by splashing of molten steel are eliminated quickly; and accordingly, environmental pollution is avoided.

Description

technical field [0001] The invention relates to the technical field of converter dedusting, in particular to a system and method for treating a converter dedusting device with poor dedusting effect due to converter splashing. Background technique [0002] In converter steelmaking, due to the uncertainty of the manual operation of steel workers, the molten steel in the converter often splashes; every splash will cause the flue gas generated by the converter to increase instantaneously, and the dust content in the flue gas Rapid increase in a short period of time; various types of converter dust removal devices in the prior art do not have special structures and means to deal with the instantaneous increase of flue gas; in general, when the splashing phenomenon occurs, when the secondary dust removal effect is not good , the operator needs to increase the opening of the throat of the secondary flap venturi or increase the opening of the annular venturi, and at the same time in...
