Abstract

The invention relates to a test device for determining parameters of steam explosion technology, belonging to physics test equipment. In the current technology mode, which realizes steam explosion through fast valve opening, long pressure release time reduces the energy density, so the material decomposition degree is low, little facilitating later enzymatic hydrolysis. The technological test bench based on the principle of cylinder explosion piston provided by the invention can finish the steam explosion within milliseconds, improving the energy density and fully decomposing the material. The technical principle of the test bench is also reflected in the design of industrial steam explosion devices, which accurately simulates the production environment for future industrialization of steam explosion and, thereby, accurately determining parameters of the steam explosion technology and providing fiber pretreatment materials for metaphase experiments of biochemical treatment such as enzymatic hydrolysis and the like. Experiments of the invention are relatively independent, creating conditions for contrast tests and final parameter determination.

Description

technical field [0001] The invention relates to a test device for determining process parameters of a steam explosion process, which is a physical test device. Background technique [0002] The technical essence of Steam Explosion is to release the compressed gas that has penetrated into the plant tissue in a short period of time, and the purpose is to decompose the raw materials according to the purpose with less energy. The steam explosion machine suspends the raw materials in the container in the air space in the form of explosion in the range of milliseconds. Due to its short action time, high energy density and concentration, steam molecules can penetrate between macromolecules such as cellulose and lignin, and can fully decompose materials at the macromolecular level, creating basic conditions for later biochemical treatments such as enzymatic hydrolysis. . [0003] The basic mode of the current steam explosion technology is: a valve is installed at the bottom of a p...

AI Technical Summary

Problems solved by technology

This kind of technological process does not fill explosive compressed gas energy in the way that the gas penetrates into the plant tissue, and makes it explode and release in a short time. Horizontally break the original cellulose macromolecular lattice

The result is a huge power consumption to compress the solid, but does not produce the desired effect of the pretreatment of the cellulosic material, and does not help much in the later enzymatic hydrolysis
