Converter gas dry dedusting fine dust pneumatic transport system

Abstract

The invention relates to a converter gas dry dedusting fine dust pneumatic transport system, comprising a dry filter bag deduster (1), a first horizontal chain conveyor (2), a second horizontal chain conveyor (3), a cutting-out chain conveyor (4), a dust unloading main pipe (5), a pneumatic tee distributor (7), a first dust unloading branch pipe (10), a second dust unloading branch pipe (15), a first bin pump (13), a second bin pump (18), a pneumatic conveyor pipe (26) and a fine dust bin (27); and the first bin pump (13) and the second bin pump (18) are connected with the fine dust bin (27) by the pneumatic conveyor pipe (26). The converter gas dry dedusting fine dust pneumatic transport system has no spark discharging as adopting the dry filter bag deduster, thus completely solving the problem of leakage-explosion of static dedusters. The loop for conveying the fine dust is reduced, the fault rate of the equipment is greatly reduced, and the storage and conveying of the fine dust bin are not limited by occasions and distances.

Description

technical field [0001] The invention relates to the field of environmental protection equipment, and more specifically relates to a pneumatic conveying system for converter gas dry dedusting fine ash. Background technique [0002] With the increasing awareness of environmental protection, most newly built and rebuilt converters use dry dust removal. The existing fine ash conveying technology for dry dust removal is: the fine ash collected by the electrostatic precipitator passes through the built-in chain conveyor, pneumatic flapper valve, pneumatic double flap valve, external chain conveyor, screw conveyor, bucket conveyor, etc. The hoist sends it to the fine ash bin outside the main workshop, and is transported by car after humidification. [0003] The main problems of the existing fine ash conveying technology for dry dust removal are as follows: first, the electrostatic precipitator is prone to explosion, and the equipment is easy to be damaged, which seriously affects ...

AI Technical Summary

Problems solved by technology

[0003] The main problems of the existing fine ash conveying technology for dry dust removal are as follows: first, the electrostatic precipitator is prone to explosion, and the equipment is easy to be damaged, which seriously affects the normal production of the converter; Affect the normal production of the converter; third, the storage and transportation of fine ash are limited by the site and distance; fourth, the humidification of fine ash is not uniform, resulting in dust everywhere during ash unloading, polluting the environment
