Description

Technical Field

[0001] The utility model relates to the technical field of furfural production, in particular to a furfural biomass raw material processing device. Background Art

[0002] Furfural is an important chemical extracted from agricultural byproducts such as corn cobs, rice husks, wood fibers, wheat straw and other crop residues. It is widely used in the production of refined lubricant precursors, pesticides, pharmaceuticals and plastics. In the production process of furfural, the treatment of biomass raw materials is one of the key steps, which directly affects the extraction efficiency and product quality of furfural. Traditional biomass raw material processing methods usually include material crushing, cooking, acid hydrolysis and other steps, but there are problems such as low processing efficiency, high environmental pollution, high energy consumption and inability to achieve continuous production;

[0003] The invention patent with application number 202111322905.7 discloses a method and device for pretreating corncob raw materials for furfural production. By utilizing deoxygenation baking, the cellulose and lignin of the corncob are destroyed, which is beneficial to the full reaction of the hydrolysis link in the furfural preparation process and improves the furfural yield. The deoxygenation baking process reduces the oxygen content of the corncob fragments, which is beneficial to reduce by-products such as organic acids in the acid-catalyzed hydrolysis of furfural, improve the yield of furfural, and reduce the emission of "three wastes". Repeated extrusion is used to further remove oxygen from the corncob fragments and to promote the uniform mixing of the corncob fragments and the acid catalyst;

[0004] However, the above-mentioned method and device for pretreating corn cob raw materials for furfural production adopt batch processing, which leads to a long production cycle and is difficult to meet the needs of large-scale continuous production. The waste residue generated after extrusion of the mixed material after acid mixing in the above-mentioned method and device for pretreating corn cob raw materials for furfural production is not harmlessly treated, resulting in a low utilization rate of the raw materials. Directly discarding the waste residue is likely to cause environmental pollution. Therefore, the utility model proposes a furfural biomass raw material processing device to solve the problems existing in the prior art. Utility Model Content
