Description

Technical Field

[0001] The utility model belongs to the technical field of smoke mixers, in particular to a typhoon-resistant smoke mixer. Background Art

[0002] The sintering flue gas recycling process refers to a process in which a portion of the hot flue gas generated during the sintering process is not discharged into the atmosphere, but is returned to the sintering material surface for reuse after simple treatment, thereby reducing the sintering solid fuel consumption and waste gas emissions. Usually, in order to ensure the sintering effect, the flue gas needs to be mixed by a flue gas mixer (also called a homogenizer) before returning to the sintering material surface, so that the flue gas temperature and composition are evenly mixed before returning to the sintering material surface.

[0003] The gas mixer proposed by our company previously, with publication number CN205537154U, includes a mixing cylinder and a guide body located in the mixing cylinder, coaxially arranged with the same bottom surface; an air outlet pipe is arranged at the upper end of the side wall of the mixing cylinder; two air inlet pipes are symmetrically arranged at the lower end of the side wall of the mixing cylinder, with the center of the bottom surface of the mixing cylinder as the symmetrical point, and the air inlets of the two air inlet pipes are opposite to each other, so that the respective air flows rotate in the same direction around the guide body; a baffle is arranged at the top of the mixing cylinder, and the mixed gas is led out from the outlet of the air outlet pipe through the blocking of the baffle. The gas mixer has a simple structure and is easy to install. It can achieve full mixing of the two gases without rotating parts and any power.
