Steam explosion device for plant fiber processing

Abstract

The invention relates to a steam explosion device for plant fiber processing. The device comprises an outer bin, an annular cover plate, an inner bin, a bottom cover, an annular bottom plate, an innercover, at least one first sealing strip, a second sealing strip and at least one third sealing strip, wherein the lower opening end of the outer bin is provided with a lower connecting part, two endsof the lower connecting part are provided with first sealing grooves, the side wall of the outer bin is provided with an air inlet hole, and a high-temperature high-pressure air inlet pipe is inserted in the air inlet hole; the annular cover plate covers an upper opening end of the outer bin, the portion, at two ends of the inner side of the upper opening end, of the annular cover plate is provided with a second sealing groove; the inner bin is inserted in the outer bin; the bottom cover covers a lower end port of the inner bin, and two ends of the upper surface of the bottom cover are provided with first sealing bulges; the annular bottom plate covers the upper end of the inner bin, two ends of the upper surface of the annular bottom plate are respectively provided with second sealing bulges, two ends of the lower surface of the annular bottom plate are provided with third sealing grooves; the inner cover covers the lower surface of the annular bottom plate, and two ends of the uppersurface of the inner cover are provided with third sealing bulges. The steam explosion device for the plant fiber processing has the advantages that it can be achieved that a plant fiber can performsteam explosion under the effect of medium-high-pressure saturated steam, so that a fiber can be separated from other substances in the plant fiber, thereby realizing the real steam explosion processing of a plant.

Description

technical field [0001] The invention belongs to the technical field of steam explosion, in particular to a steam explosion device for processing plant fibers. Background technique [0002] Steam explosion, that is, steam explosion, is a technology that uses the explosion process realized by the principle of steam catapult to pretreat biomass. [0003] The essence of its technology is: to release the steam molecules infiltrated into the plant tissue instantaneously, so that the internal energy of the steam can be converted into mechanical energy and act on the interlayer of biomass tissue cells, so that the raw materials can be decomposed according to the purpose with less energy. Because it not only avoids the secondary pollution problem of chemical treatment, but also solves the problem of low efficiency of biological treatment, it is the most promising pretreatment technology in the field of biomass conversion. [0004] The fibers in plant cells are bonded by lignin. Unde...
