Efficient energy-saving ash falling and conveying method

Abstract

The invention discloses an efficient energy-saving ash falling and conveying method, and relates to the technical field of dust removing equipment in the metallurgy industry. The efficient energy-saving ash falling and conveying method comprises a compressed air pump, a tower bottom slag removing ash bucket, a reducing section, a cutter-shaped gate valve, a pipe, a waveform compensator, a double-gate plate feed valve, a sender, a main ash conveying pipe and a double-sleeve inner pipe. The efficient energy-saving ash falling and conveying method can guarantee smooth flowing and conveying of materials after five steps, prevents adhesive particles from easily attaching on the inner wall of the pipe to form cakes, and guarantees the material performance and smooth material conveying.

Description

technical field [0001] The invention relates to a method for transporting ash and belongs to the technical field of dust removal equipment in the metallurgical industry. Background technique [0002] In recent years, with the continuous deterioration of air quality, the continuous emergence of smog weather, and the continuous force of environmental protection storms, the importance of environmental protection equipment in various iron and steel industries is even more important. In recent years, dry dust removal technology has been introduced from abroad in China. Compared with OG dust removal, that is, unburned method, wet purification and recovery system, dry dust removal has the advantages of high dust removal efficiency, low energy consumption, and small footprint; the disadvantage is equipment maintenance. Large quantity, high equipment operation cost, especially serious wear and tear of ash conveying chain and slideway, high system failure, resulting in equipment accid...

In recent years, dry dust removal technology has been introduced from abroad in China. Compared with OG dust removal, that is, unburned method, wet purification and recovery system, dry dust removal has the advantages of high dust removal efficiency, low energy consumption, and small footprint; the disadvantage is equipment maintenance. Large quantity, high equipment operation cost, especially the serious wear and tear of the ash conveying chain and slideway, high system failure, resulting in equipment accidents such as converter shutdown failure, electrostatic precipitator shutdown and smoke, etc., increasing the number of replacement and maintenance of equipment
