Problems solved by technology

However, the existing steam flash explosion method for processing plant biomass fails to scientifically process the plant biomass in the early stage, resulting in the gas compression inside the plant biomass tissue of the explosive being unable to be released instantly in the form of implosion. , but is gradually released from the plant tissue, resulting in incomplete and uneven decomposition of the plant biomass tissue, carbonization of the plant biomass tissue, and damage to a large number of fibers, which lead to the existing steam flash explosion method. Difficult to achieve industrial production

Abstract

The invention discloses a method for blasting plant biomass walls with oxygen, comprising the following steps of: firstly, adding ethanol, hydrogen peroxide with concentration of 30% and water to crushed plant biomass, mixing the materials to oxidize and soak the materials, and conveying the oxidized and soaked materials to an oxygen blasting tank via a feeding port of the oxygen blasting tank; secondly, sealing the feeding port of the oxygen blasting tank, regulating the temperature of the gas in the oxygen blast tank at 80-150 DEG C and the pressure within 1-4 MPa by conveying pressure air to the oxygen blasting tank, preserving heat and keeping pressure for 20-200 seconds to soak the plant biomass into ethanol, hydrogen peroxide with concentration of 30%, steam and water; and finally, completely opening the discharge port of the oxygen blasting tank within 3 seconds to reduce the pressure in the oxygen blasting tank to the normal pressure. The invention aims to provide the method for blasting plant biomass walls with oxygen, which can be used for completely and uniformly decomposing the plant biomass and realizing industrialization production and has high production efficiency.

Description

technical field [0001] The present invention relates to a method for oxygen blasting wall plant biomass. Background technique [0002] Existing methods for treating plant biomass include a steam flash explosion method, which usually first puts the plant biomass into a container, then enters a certain pressure of saturated steam into the container, and uses the saturated steam to detonate the material in the container. After treatment, the material is put into the atmospheric pressure environment, and the rapid expansion of the steam entering the plant biomass tissue is used to break down the plant tissue. However, the existing steam flash explosion method for processing plant biomass fails to scientifically process the plant biomass in the early stage, resulting in the gas compression inside the plant biomass tissue of the explosive being unable to be released instantly in the form of implosion. , but is gradually released from the plant tissue, resulting in incomplete and ...
