Attic type gravity dust collector

Abstract

The invention discloses an attic type gravity dust collector which consists of a settling chamber and a soot cleaning car. The gravity dust collector is characterized in that the settling chamber is installed on the house beam of a workshop building and composed of a circumferentially closed metal head cover and a bottom consisting of clapboard type filter group, and the soot cleaning car is installed on the track of a crane and provided with a soot cleaning car touch wheel. The attic type gravity dust collector has the advantages that the metallic structure is high temperature resistant; the soot self circulation is completed by using the soot temperature difference as dynamic force; the higher the soot temperature, the better the dust removing effect; the soot can enter the dust collector for treatment without cooling and has small volume; the dust content is high, the dust removing efficiency is high and the exhaust soot amount is small; the dust collector is installed in the air of the workshop building with compact structure and no land occupying; the soot cleaning is carried out mechanically without maintenance management by specially-assigned persons; the disposable investment is small; the operating cost is low with economy and practicability, and the energy-saving and emission-reduction effect is obvious; and the utility value of the recovered dust is high and the recovery period of the invested capital is short.

Description

technical field [0001] The invention relates to a dust collector, in particular to a loft-type gravity dust collector for treating high temperature smoke and dust of furnaces. Background technique [0002] At present, the kiln flue dust collector has many shortcomings, mainly including: low dust removal efficiency, unable to meet the requirements of the existing environmental protection fume emission standards; It cannot be applied to furnaces with disorderly discharge of smoke and dust, such as electric arc steelmaking furnaces; the dust accumulated in the gravity sedimentation chamber can only be cleaned manually, and cannot be operated mechanized. SUMMARY OF THE INVENTION [0003] Aiming at the deficiencies of the prior art, the present invention provides a loft-type gravity dust collector installed on the beam on the top of the factory building above the furnace. [0004] The technical feature of the invention is that the attic gravity dust collector is composed of tw...
