Problems solved by technology

[0004] Due to the large amount of converter blowing flue gas and large fluctuations, the electrostatic precipitator itself is limited by the inherent characteristics of the electrostatic precipitator, such as back corona caused by high specific resistance dust, secondary dust caused by rapping, and insufficient charge of fine dust. It is difficult to achieve a stable outlet emission concentration of ≤10mg / Nm3. At the same time, there are also the following problems: high energy consumption for dust removal, water consumption, waste liquid and mud treatment problems, and it is not conducive to the subsequent removal of carbon monoxide from flue gas.

Description

Technical field[0001]The present invention belongs to the field of dust removal applications, and more particularly to a dry ultimate exhaust dust removal device.Background technique[0002]A large amount of high temperature, toxic and dust-shaped flue gas is generated when converting steel is generated, and the main components of carbon monoxide and various dust particulate contaminants.[0003]At present, the transformer is generally used in the process of "dry law" and "wet" process. Since the dry process has certain energy saving and technical advantages, the mainstream of the transformer is mainstream in the transfority of "dry method" dust removal process. It is 1200 ° C high temperature flue gas to cool to about 800 to 1000 ° C, and then enter the evaporative cooler, and the atomized water ejected by the aerosol nozzle is cooled to 200 ° C, while most of the crude particles are intercepted. The remaining flue gas enters the electric precipitator, due to the electrostatic adsorpti...
