The present invention can be implemented or applied by other different specific embodiments, and various details in the present specification can be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It is to be noted that the features in the following embodiments and examples may be combined with each other without conflict.
It should be noted that the drawings provided in the following embodiments are only for illustrating the basic concept of the present invention, and the components related to the present invention are only shown in the drawings rather than drawn according to the number, shape and size of the components in actual implementation, and the form, amount and ratio of the components in actual implementation may be changed at will, and the layout of the components may be more complicated.
Compared with the primary dust removal of a production process, the primary dust removal refers to a process of searching, cooling and purifying high-temperature flue gas generated in a converter smelting process through a vaporization flue, and in order to achieve the purposes of saving energy and protecting equipment, a fan for primary dust removal generally runs at a low speed in the later stage of converter tapping, slag splashing, slag pouring and steel scrap adding, and thus the primary dust removal cannot play a good dust removal role in part of smelting links. Although less smoke and dust are generated in the converter in the non-converting time, part of the smoke and dust still overflows a converter mouth, meanwhile, in the converting process of the converter, in order to recover coal gas, the converter mouth needs certain micro-positive pressure difference operation, the operation is to ensure that flame after the converter overflows slightly, all the smoke and dust are not absorbed directly, and certain smoke and dust is generated in the processes of certain smoke and dust escaping and tapping and the like during converting, so secondary dust removal and other equipment are matched.
Referring to fig. 1, the present invention provides a secondary dust removing device for a converter, which comprises a dust removing pipeline 02, a valve assembly 03, a fan 01 and a driving control end 05.
