High-efficiency environmental fume purification system

Abstract

The invention discloses a high-efficiency environmental fume purification system. The system comprises fume hoods (1) which are respectively arranged at the charge opening, a copper outlet and a slagoutlet of an oxygen-enriched side blown converter, wherein the fume vent of each fume hood is connected with a fume inlet of a cyclone dust collector (3) through a first air fume pipe (2), and the smoke outlet of the cyclone dust collector is connected with the fume inlet of a spray dust collector (5) through a second air fume pipe (4); the fume outlet of the spray dust collector is connected witha fume exhaust cylinder (9) through a third air fume pipe (6), an induced draft fan (7) and a fourth air fume pipe (8); at least two dust collection cavities (31) are formed inside the cyclone dust collector, a spiral structure (32) is arranged in each dust collection cavity; the bottom of the cyclone dust collector is provided with an outlet (14) through a start-shaped ash valve (13) ; and gas distributors (54) are arranged in the cavities of the spray dust collector, and is used for uniformly distributing gases, and the cavity is divided into an air inlet chamber and a spray chamber by virtue of the gas distributor, and a plurality sprayers are arranged at the upper part of the spray chamber.

Description

technical field [0001] The invention relates to an environmental smoke collection and dust collection system, in particular to a high-efficiency environmental smoke purification system. Background technique [0002] At present, the general environmental dust collection technology is to use cyclone to collect dust at the smoke collection port, and then pass through bag dust removal, and then the smoke is discharged from the exhaust pipe. Using this technology to collect dust often results in blockage of the bag due to too much moisture in the flue gas entering the bag dust collector, which leads to the paralysis of the entire environmental dust collection system. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a high-efficiency environmental flue gas purification system for oxygen-enriched side-blown furnaces that can make the smoke and dust collection system run smoo...
