Dust unloading control method and device for electric dust remover of sintering machine head

Abstract

The embodiment of the invention discloses a dust unloading control method and device for an electric dust remover of a sintering machine head. Through analysis of actions of a material level switch in a dust storage bin in the electric dust remover of the sintering machine head, the working dust unloading period of the dust storage bin is automatically adjusted, the dust unloading period of the dust storage bin can automatically adapt to the change of the dust removal amount of the electric dust remover of the sintering machine head in the sintering production process, and therefore accurate dust unloading, adapting to the production change, of the electric dust remover of the sintering machine head is achieved, and healthy and stable operation of the electric dust remover of the sintering machine head is guaranteed. Existing system hardware of the electric dust remover of the sintering machine head does not need to be changed, and accurate dust unloading can be achieved with low cost. Meanwhile, after the dust unloading period of the dust storage bin of the electric dust remover of the sintering machine head automatically adapts to sintering production, the material level switch in the dust storage bin cannot participate in or less participate in dust unloading control, the loss opportunity of the material level switch is effectively reduced, and the service life of the material level switch is greatly prolonged.

Description

technical field [0001] The invention relates to the technical field of dust removal, in particular to a method and device for controlling ash discharge of an electric dust collector of a sintering head. Background technique [0002] The dust-containing gas generated in sintering production needs to be treated by the electrostatic precipitator of the sintering head before being discharged into the atmosphere. Therefore, the electrostatic precipitator of the sintering head is an important environmental protection equipment in the sintering production. The sintering head electrostatic precipitator in the sintering system is usually a multi-electric field precipitator, that is, it has a multi-electric field (such as three electric fields or four electric fields) structure. [0003] Taking the three electric fields as an example, such as figure 1 As shown, the sintering head electrostatic precipitator equipped with three electric fields includes the first electric field 02, the ...
