Description

Technical Field

[0001] This utility model relates to the technical field of baking soda grinding devices, and in particular to a baking soda grinding device for flue gas treatment. Background Technology

[0002] In the field of industrial flue gas treatment, baking soda (sodium bicarbonate) is widely used in dry or semi-dry desulfurization processes due to its excellent desulfurization, denitrification, and acid gas adsorption capabilities. Its working principle involves grinding baking soda to a specific particle size, utilizing its large specific surface area to chemically react with pollutants such as sulfur dioxide and nitrogen oxides in the flue gas, thereby purifying the flue gas. The particle size uniformity and grinding efficiency of the baking soda directly affect the effectiveness and cost of flue gas treatment.

[0003] Regarding the aforementioned technologies, it has been found that the grinding methods of traditional hammer mills or ball mills rely on the free dispersion of materials. The distribution of baking soda lumps in the grinding chamber is uneven, and some areas may be insufficiently ground due to accumulation. Especially when the processing volume is large, the grinding time is significantly extended, making it difficult to meet the continuous production needs of industrial flue gas treatment.

[0004] Meanwhile, due to the lack of an effective material collection device, baking soda blocks are easily scattered everywhere when traditional grinding equipment is in operation due to the high-speed impact of the hammer or steel ball. This not only wastes materials but also leads to excessively high dust concentration in the working environment, posing a safety hazard. Utility Model Content
