2results about How to "Fast desulfurization reaction" patented technology

The invention provides environment-friendly fluoride-free KR desulfurization powder which comprises the following components in percentage by mass: 78-90% of CaO; 1%-4% of Al; 4%-8% of Al2O3; 0 to 3 percent of SiO2; 0 to 3 percent of MgO; 0 to 0.05 percent of S; the balance is impurities; traditional fluorite is not used as a fluxing agent, so that the environment is not polluted, a ladle is not eroded, and the steelmaking cost is reduced; high-efficiency desulfurization is realized, Al2O3 can be generated by combining with free oxygen in molten iron, the oxygen activity is reduced, and the desulfurization reaction speed can be further increased; and compensating temperature drop. The formula is simple, and the problems that fluorite is harmful to the environment and can erode ladles, and the steelmaking cost is increased are solved.

The utility model discloses a kind of barium residue comprehensive treatment desulfurization device, it is related to barium residue processing technical field, including grinding mechanism, the grinding mechanism includes support frame, the upper end of the support frame is fixedly connected with grinding bin, the top of the grinding bin is provided with outer flange;Desulfurization mechanism.The utility model is through the setting of grinding mechanism, flared annular feed inlet is convenient for barium residue even into grinding bin, first motor drives grinding head to rotate, barium residue is fully ground and refined, increase the specific surface area of barium residue, so that subsequent desulfurization reaction, desulfurization liquid can be contacted with barium residue all-round, fully, improve the efficiency and full degree of desulfurization reaction, the setting of pressurizing assembly simultaneously, pressurizing gas pump injects gas into reaction kettle through pressurizing pipe, improve the pressure in reaction kettle, appropriate pressurization accelerates the collision frequency between molecules, to significantly accelerate desulfurization reaction speed.
