Description

Technical Field

[0001] The utility model relates to a multi-stage cooling device for desulfurizing agent production, belonging to the technical field of desulfurizing agent production. Background Art

[0002] Desulfurizer generally refers to an agent for removing free sulfur or sulfur compounds from fuel, raw materials or other materials. In the control and treatment of pollutants, it mainly refers to the agent used to remove sulfur oxides from exhaust gas. The most commonly used desulfurizers for removing sulfur dioxide from flue exhaust gas are cheap lime, limestone and alkaline solutions prepared with lime-based agents. Chemical plants, smelters, etc. often use sodium carbonate, alkaline aluminum sulfate and other solutions as desulfurizers to treat exhaust gas containing sulfur dioxide, which can be desorbed and recycled.

[0003] During the cooling process of the existing desulfurizer, the efficiency of the desulfurizer particles is slow when wind cooling is used, and the desulfurizer is flatly stacked, which affects the overall cooling efficiency and cooling effect of the desulfurizer. At the same time, it is difficult to automatically and continuously cool a large number of desulfurizer particles. Moreover, when the desulfurizer particles are cooled, it is difficult to discharge the desulfurizer particles quickly, and the desulfurizer particles are prone to leakage during the discharging process, which reduces the safety of automatic discharging of the desulfurizer particles.
