Problems solved by technology

However, the existing steam flash explosion method for processing straw, because it fails to scientifically process the straw in the early stage, the gas compression inside the straw tissue of the explosive material cannot be released instantly in the form of implosion, but from the plant tissue The internal was gradually released, resulting in incomplete and uneven decomposition of straw tissue, carbonization of straw tissue, and damage to a large number of fibers. As a result, the existing steam flash explosion method has been difficult to achieve industrial production.

Abstract

The invention discloses a method for blasting straw walls with oxygen, comprising the following steps of: firstly, adding liquid ammonia, carbamide, hydrogen peroxide with concentration of 30% and water to crushed straw; secondly, 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; thirdly, sealing the feeding port of the oxygen blasting tank, inputting saturated steam to the oxygen blasting tank, completely opening the feeding port of the oxygen blasting tank within 3 seconds by conveying pressure air to the oxygen blasting tank, and making the pressure in the oxygen blasting tank instantly reduce to the normal pressure. A device for blasting straw walls with oxygen comprises a straw crusher, a straw conveyor, a storage cabin, a premixing machine, a material lifter, a rotary feeder and an oxygen blasting tank. The invention aims to provide the method and device for blasting straw walls with oxygen, by which straw tissues can be completely and uniformly decomposed, high production efficiency can be achieved and industrialization production can be realized.

Description

technical field [0001] The invention relates to a method for blasting wall straw with oxygen. Background technique [0002] The existing methods for processing straw include the steam flash explosion method, which usually first puts the straw into a container, then enters a certain pressure of saturated steam into the container, uses the saturated steam to process the material in the container, and then puts the The material is placed in an atmospheric pressure environment, and the rapid expansion of the steam entering the straw tissue causes the plant tissue to break down and decompose. However, the existing steam flash explosion method for processing straw, because it fails to scientifically process the straw in the early stage, the gas compression inside the straw tissue of the explosive material cannot be released instantly in the form of implosion, but from the plant tissue The internal was gradually released, resulting in incomplete and uneven decomposition of the str...
