Description

Technical Field

[0001] The utility model relates to the technical field of steam explosion, in particular to an industrialized steam flash explosion straw wall breaking device. Background Art

[0002] Steam explosion is a technology that uses the steam ejection principle to realize the explosion process for pre-treatment of biomass. The fibers in plant cells are bonded by lignin. Under the action of high temperature and high pressure steam, the crystallinity of cellulose increases, the degree of polymerization decreases, the hemicellulose is partially degraded, the lignin softens, the transverse connection strength decreases, and it may even soften and plasticize. When the material filled with pressurized steam is suddenly decompressed, the gas in the pores expands dramatically, producing an "explosion" effect, which can partially strip off the lignin and tear the raw material into fine fibers. Steam explosion is a good way to process straw materials and extract cellulose.
