Abstract

The invention discloses a secondary smoke trapping device for a buffering type rotary furnace. The device comprises a smoke collecting pipe provided with a smoke collecting port and a buffering element, wherein the smoke collecting pipe is mechanically connected with the buffering element by an elastic component, and the opening of the smoke collecting pipe is rightly aligned to the opening of the rotary furnace. The device disclosed by the invention has the advantages that the secondary smoke of the rotary furnace is trapped in high efficiency and low consumption.

Description

technical field [0001] The invention relates to a secondary flue gas purification facility of a steelmaking converter in an iron and steel enterprise, in particular to a steelmaking buffer type converter secondary flue gas collection device. Background technique [0002] As we all know, environmental protection is a basic national policy that must be adhered to for a long time. Under the strong promotion of national policies and the supervision of public opinion, all iron and steel enterprises have put forward higher requirements for the environmental protection of plant areas. [0003] At present, the traditional steelmaking converter secondary flue gas capture device cannot capture the flue gas generated during the production process of the converter with high efficiency and low consumption. energy. [0004] In order to improve the collection efficiency, the method of increasing the dust removal air volume of the system is generally adopted at home and abroad. Although t...
