Problems solved by technology

When operating alone, selective catalytic reduction has a good effect on NOx removal, but requires a high-efficiency catalyst and the operating cost is seriously affected by the life of the catalyst; selective non-catalytic reduction has a strict temperature window for a specific reducing agent, otherwise the removal effect will be poor, and the It may cause ammonia leakage, and the removal rate of NOx is only about 40% to 60%, so it is often used as a supplementary means of low NOx combustion technology
Generally, biomass fuels, especially cell-structured colloidal biomass residues and other biomass raw materials, still have higher water content than fossil fuels, and may contain a certain amount of alkali (earth) metals, sulfur, chlorine and other elements, and the combustion is stable. It is difficult to adapt to the removal of NOx in the combustion process, whether it is selective catalytic reduction or selective non-catalytic reduction.

Abstract

The invention relates to a method for energizing grain residues of cellular structure colloid type biomasses. The method includes hydro-thermal treatment, mechanical dehydration, and rich water vapor combustion. According to the method for energizing the grain residues of cellular structure colloid type biomasses, a plurality of the cellular structure colloid type biomasses and waste, particularly fermentation pharmaceutical grain residues, are subjected to biomass energy efficient recycle and toxic and harmful substance thorough hazard-free treatment, few apparatuses are required, an occupation area is small, investment and operation costs are low, engineering enlargement can be easily performed, and the method is applicable to enterprises with various sizes.

Description

technical field [0001] The invention relates to the application field of waste resource utilization, in particular, the invention relates to a method for energy utilization of cell structure colloidal biomass residue. Background technique [0002] Cell structure colloidal biomass dregs (especially industrial fermentation dregs) usually have a high water content, rich in organic matter, and some even contain toxic and harmful substances (such as the unextracted potency of dregs left in the process of fermentation and production of antibiotics in the pharmaceutical industry ), easily corrupted and deteriorated, overflowing waste liquid with high organic concentration and releasing foul-smelling gas, causing serious environmental pollution. The traditional cell-structured colloidal biomass residue energy conversion method is shown in figure 1 , because the extracellular water in this kind of biomass-rich waste mainly exists in the form of non-free water (including interstitial...
