Description

Technical Field

[0002] In the production of wet corn starch, corn needs to be soaked. The resulting corn soaking water contains approximately 7% soluble substances, mainly soluble proteins, carbohydrates, ash, oils, starch, and lactic acid. To fully utilize these components, people have begun to use corn soaking water to extract other valuable products, such as inositol. Inositol is extracted using modern processing techniques and processed into food-grade additives. However, the extraction of inositol generates nitrogen-containing ammonia-based organic waste gas. Direct emission of this waste gas causes significant environmental pollution. Common methods for treating these gases include chemical reagent methods, adsorption methods, and combustion methods. In the combustion method for treating organic waste, waste heat recovery devices are needed to recover and utilize the residual heat from the flue gas.
