Problems solved by technology
Although the capture efficiency of the secondary flue gas of the converter has been improved to a certain extent, the capacity of the corresponding dust removal equipment must be expanded to increase the air volume of the system, which not only increases the initial investment of the equipment, but also greatly increases the operating cost, which cannot meet the national energy conservation and emission reduction requirements. related requirements

The invention relates to a novel gas curtain type revolving furnace secondary flue gas capture device which comprises gas curtain devices and a capture cover, wherein the gas curtain devices are respectively arranged on two sides of a steel and slag transport channel, and the capture cover is arranged on a revolving furnace; the capture cover is communicated with an external dedusting pipeline through an exhaust pipe; the capture cover, the gas curtain devices, the revolving furnace, a molten iron tank arranged above the revolving furnace and a smoke proof chamber form a relatively sealed space; the revolving furnace is arranged in the smoke proof chamber; each gas curtain device comprises a compressed gas supplying pipe connected with an external gas source; each compressed gas supplying pipe is connected with a wall face of the steel and slag transport channel through a bracket and is provided with a plurality of gas outlet devices. The novel gas curtain type revolving furnace secondary flue gas capture device has the beneficial effects that: 1, the novel gas curtain type revolving furnace secondary flue gas capture device is simple in structure and convenient to implement; and 2, the novel gas curtain type revolving furnace secondary flue gas capture device can reduce the volume of wild wind entering the capture cover arranged above the revolving furnace, is beneficial for the capture cover to perform high-efficiency and low-energy-consumption capture of revolving furnace secondary flue gas before a large number of diffusion of the revolving furnace secondary flue gas is generated, and has the advantage of energy saving and environmental protection.
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 novel air curtain type converter secondary flue gas collecting 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 air curtain type 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. Althou...
