Problems solved by technology

[0003] At present, a large amount of exhaust gas will be generated in the process of iron and steel smelting. If these exhaust gases are directly discharged to the outside, it will easily cause pollution. The current equipment for purification of iron and steel smelting exhaust gas is generally convenient.

Abstract

The invention discloses a flue with a purification function and steel smelting equipment. The flue comprises a first smoke inlet pipe, a second smoke inlet pipe and an air exhaust pipe. A first air inlet pipe, a second air inlet pipe, a first funnel and a second funnel are arranged in the air exhaust pipe. A butterfly valve is arranged on the first funnel, a storage cavity is formed between the first funnel and the second funnel, reaction liquid is arranged in the storage cavity, reaction liquid is inserted into one end of the first gas inlet pipe and one end of the second gas inlet pipe, a rotational flow plate and an air exhaust rotary vane are arranged above the second funnel, a double-shaft motor is arranged between the rotational flow plate and the air exhaust rotary vane, a tail endof the air exhaust pipe is sequentially connected with a first filtering device, a second filtering device and an air exhaust device, and the first filtering device, the second filtering device and the air exhaust device are all detachably connected with the air exhaust pipe. The flue with a purification function has good use convenience.

Description

technical field [0001] The invention relates to a flue and iron and steel smelting equipment with purification function. Background technique [0002] Most modern ironmaking uses blast furnace ironmaking, and some use direct reduction ironmaking method and electric furnace ironmaking method. Steelmaking mainly uses pig iron smelted in blast furnaces, sponge iron smelted by direct reduction ironmaking, and scrap steel as raw materials, which are smelted into steel by different methods. The basic production process is to smelt iron ore into pig iron in an iron-smelting furnace, then use pig iron as raw material to smelt steel by different methods, and then cast it into ingots or continuous casting slabs. [0003] At present, a large amount of exhaust gas will be generated in the process of iron and steel smelting. If these exhaust gases are directly discharged to the outside, it will easily cause pollution. The current equipment for purification of iron and steel smelting exh...
