Problems solved by technology
Now beet sugar factory filter sludge is basically piled up in the open air and landfilled. In theory, it can be used to process clinker in the cement industry, but due to the high cost of transportation and storage, it is rarely realized.
The above methods not only increase the cost to the enterprise, but also cause environmental problems
Limestone-gypsum method uses a large amount of limestone for industrial desulfurization, and the calcium-sulfur ratio is greater than 2:1. Combined with crushing and grinding, the cost is very high, and the environmental protection problems in stacking, crushing, grinding and other links are very serious, not only noise, but also dust And other problems, and the cost is very high, wasting a lot of energy and human resources

Embodiment 1
[0011] Application of beet sugar factory filter sludge in industrial boiler desulfurization project. For decades, filter mud from Xinjiang sugar factory to Heilongjiang beet sugar factory has been used as an industrial waste, stored in the open air, causing dust to fly, polluting the environment, and constantly needing to occupy a larger area of the site. People think this is the only way to do it. Solve, if production will produce pollution and produce filter mud, for many years, the environmental protection problem is very big, can not solve all the time.
[0012] The present invention uses sugar beet sugar mill filter mud instead of limestone for industrial boiler desulfurization, and the desulfurization process is the same as the limestone gypsum desulfurization process.
[0013] The limestone gypsum desulfurization process is a traditional process. During the desulfurization process, the circulating fluidized bed boiler can directly mix and burn a certain proportion of ...

The invention relates to application of filtered mud of a beet sugar factory to industrial boiler desulfurizing items. At present, the limestone-plaster method is an industrial desulfurizing method with the most mature technology, the widest range of application and the lowest cost. But the process from mining to crushing the limestone into powder needs higher cost, however, the prior filtered mud of the beet sugar factory is basically piled up and embedded in the open air, so theoretically, the filtered mud can be used for processing clinker for the cement industry, but because the cost of the transportation and storage is high, the application the filtered mud to processing the clinker is difficult to achieve. The invention applies the filtered mud of the beet sugar factory to the industrial boiler desulfurizing items to replace the conventional limestone powder, and is used for the industrial boiler desulfurization.
Description
Technical field: [0001] The invention relates to the application of beet sugar factory filter mud in industrial boiler desulfurization projects. Background technique: [0002] At present, the limestone-gypsum desulfurization method is the most mature technology, the most widely used and the lowest cost industrial desulfurization method. However, limestone requires a large cost from mining to crushing into powder. Now beet sugar factory filter sludge is basically stacked in the open air and landfilled. Theoretically, it can be used in the cement industry to process clinker, but due to the high cost of transportation and storage, it is rarely realized. The above methods not only increase the cost to the enterprise, but also cause environmental problems. Limestone-gypsum method uses a large amount of limestone for industrial desulfurization, and the calcium-sulfur ratio is greater than 2:1. Combined with crushing and grinding, the cost is very high, and the environmental prot...
