specific Embodiment approach 1

[0005] Specific embodiment 1: Referring to Fig. 1, this embodiment is realized in the following way: a, the straw silk of herbaceous plant is added in the oxygen stir-fried separation straw silk machine; b, preparation auxiliary agent, described auxiliary agent is made of the following components Mixed according to weight percentage: alkali 3-10%, alkaline hydrogen peroxide 70-85%, sodium silicate 3-10%, grafted starch 0.5-1.5%, magnesium sulfate 0.5-2%, chlorine oxygen 5- 15%; c. Add the prepared additives into the oxygen-stirred and separated straw silk machine, mix them evenly with the straw silk, and heat the heat-conducting oil to stir-fry the straw silk, so that the additives can quickly penetrate into the straw cavity wall, and the reaction temperature The temperature is 60-90°C, the reaction time is 100-120 minutes per ton of material, and the amount of additives added is 3-5% of the total weight of the material.

specific Embodiment approach 2

[0006] Specific embodiment 2: The difference between this embodiment and specific embodiment 1 is that the auxiliary agent is mixed according to the weight percentage of the following components: 4-8% of alkali, 72-82% of alkaline hydrogen peroxide, silicon Sodium phosphate 4-8%, grafted starch 0.8-1.2%, magnesium sulfate 0.8-1.8%, chlorine oxygen 8-12%. Other compositions and process parameters are the same as those in Embodiment 1.

specific Embodiment approach 3

[0007] Specific embodiment three: the difference between this embodiment and specific embodiment one is that the auxiliary agent is formed by mixing the following components according to weight percentage: 7% alkali, 75% alkaline hydrogen peroxide, and 6% sodium silicate , grafted starch 0.9%, magnesium sulfate 1.1%, chlorine oxygen 10%. Other compositions and process parameters are the same as those in Embodiment 1.

Abstract

Oxygen stewing separation method and equipment used therefor relates to a method of processing the stalk thread into stalk slurry and the equipment used therefor. The method comprises following steps: a. adding the stalk thread into the oxygen stewing separation equipment; b. preparing auxiliary, which is composed of following components by weight percent: 3-10% of alkali, 70-85% of alkaline hydrogen dioxide, 3-10 of sodium silicate, 0.5-1.5% of grafting starch, 0.5-2% of magnesium sulfate, 5-15% of chlorine-oxygen; c. adding the prepared auxiliary into the Oxygen stewing separation equipment, mixing with the stalk thread uniformly, raising the temperature to boil the stalk thread, making the stalk thread become stalk slurry, in which the reacting temperature is 150-200 DEG C, the reaction time is 100-140 mins / ton, the quantity of the auxiliary is 40-50% of the total weight.

Description

Technical field: [0001] The invention relates to a processing method and a device used in the method, in particular to a method for processing straw shreds into straw pulp under oxygen-enriched conditions and a device used in the method. Background technique: [0002] In the current paper and pulp industry, the cooking method is generally used as the first process to decompose plant fibers and other substances (lignin, sugar, etc.), and a large amount of water, electricity, heat and other energy sources are required in this process , while causing environmental pollution, and the cooking method cannot be produced continuously, and can only be produced in batches in units of steamed balls. Invention content: [0003] The object of the present invention is to provide a kind of oxygen decompression separation method which not only saves energy, but also does not pollute the environment and the equipment used in the method. The oxygen-stirred separation method of the present ...
