Abstract

The invention provides a blast furnace smoke recycling device. The blast furnace smoke recycling device comprises a tower body, a horn-shaped pipe, a smoke outlet pipe, a spraying component, a dehydrating component and a water injection pipe, wherein the horn-shaped pipe is arranged in the inner cavity of the tower body, the small end of the horn-shaped pipe extends from the top of the tower body, a predetermined space is kept between the big end of the horn-shaped pipe and the bottom of the tower body, and the spraying component is arranged above the horn-shaped pipe; the dehydrating component is arranged between the outer surface of the horn-shaped pipe and the inner surface of the wall of a tower; the smoke outlet pipe is arranged on the tower body and is communicated with the part, arranged above the dehydrating component, of the inner cavity of the tower body; the water injection pipe is arranged on the tower body and is communicated with a part, arranged below the dehydrating component, of the inner cavity of the tower body, and the water injection pipe is arranged on the big end of the horn-shaped pipe. The blast furnace smoke recycling device realizes smoke cooling, dehydrating and water sealing functions at the same time, project investment and occupying area are reduced, and the blast furnace smoke recycling device has the advantage of good cooling, dehydrating and water sealing effects.

Description

Technical field [0001] The invention relates to a blast furnace clean gas treatment equipment, and more specifically, to a device for recycling and utilizing blast furnace flue gas after dust removal and purification. Background technique [0002] The blast furnace gas is called clean gas after purification and dust removal. Because the temperature of the purified gas is relatively high, it needs to be cooled before entering the main gas pipe network. When the natural cooling method is used for cooling, there are problems such as long time and long heat dissipation pipes. At present, the most common way to cool the clean gas is water cooling, that is, by setting up a spray tower to spray cooling water mist and exchange heat with the clean gas to reduce the temperature of the clean gas. The clean gas after water cooling contains a lot of moisture. Therefore, a dehydrator is required, and a separate water seal or water seal valve is also required to achieve gas sealing. The spray...
