Problems solved by technology

Their common shortcoming is that they do not make full use of the precious natural fiber materials in rice straw, wheat straw, and asparagus. When extracting their natural fibers, they also consume a lot of alkali (NaOH ratio 1:0.6, solid-liquid ratio g:ml--- --1:30), high energy consumption (90°C, stirring 720r / min, 120min), contradicting the development of low-carbon economy

Embodiment 1

[0019] Embodiment one is raw material with rice straw

[0020] 1. Material preparation

[0021] Straw, after the rice is harvested, air-dried to dry (water content less than 10%), the blue straw must be air-dried and then turned into light brown (or light yellow-brown); cut the raw materials that have been air-dried and removed the blue color to 2cm long The broken joints are crushed into thick filaments by a hammer-type pitting machine for later use.

[0022] 2. Start anaerobic fermentation.

[0023] Put the net bag 8 in the "slag" outlet 2 of the fermentation tank in advance, and insert the insert plate 6, and put 100 mesh / cm from the feed inlet 1 2 The biogas slurry of the old biogas digester after sieving (or the pond field activated sludge slurry with an appropriate amount of water), the biogas slurry and activated sludge are rich in anaerobic bacteria. At the same time, add 4 times the volume of the old biogas tank biogas slurry prepared fermentation raw materials ...

Embodiment 2

[0033] Embodiment 2 Taking wheat straw as raw material

[0034] 1. Dry the wheat stalks after harvesting to dryness (less than 10% moisture), and the green wheat stalks must turn off-white after drying.

[0035] 2. Cut the air-dried wheat straw into 2cm-long pieces, impregnate it with clarified fresh saturated lime water (material: lime water = 1:5 parts by weight) for 24 hours, then take it out and dry it in the sun (10% water content) Below), it is crushed into thick strips by a hammer-type pitting machine.

[0036] 3. Carry out the same operations as in the steps 1-7 of Example 1 with the wheat straw prepared. Among them, 2 to 3 steps get 98 kg of dry fiber and 4 m of combustible gas. 3 , add 256 kg of wheat straw in 4 steps and prepare 256 kg of combustible gas in the process 3 , 5 steps to get 102 kg of dry fiber.

[0037] Present embodiment obtains 198 kilograms of natural fibers altogether twice, combustible gas 9m 3 (The water content of each fiber is the same a...

Embodiment 3

[0038] Embodiment three With asparagus as raw material

[0039] 1. Dry the harvested Asparagus in the sun until it is dry (9% water content), and the cyan Asparagus should be dried until it turns off-white.

[0040] 2. Cut the air-dried Asparagus japonica into 2cm-long pieces, and crush them into thick filaments through a hammer-type pitting machine, which is used as a material for the fermentation of Asparagus japonica.

[0041] 3. Carry out the same operations as in the steps 1 to 7 of Example 1 with Asparagus grass. Among them, 120 kg of dry fiber and 5 m of combustible gas are obtained in steps 2 to 3 3 , 4 steps plus 260 kg of asparagus preparations, the process yields 5.8m of combustible gas 3 , 5 steps to get 130 kg of dry fiber.

[0042] Present embodiment obtains 245 kilograms of natural fibers altogether twice, combustible gas 10.8m 3 (The water content of each fiber is the same as in Example 1).

Abstract

The invention discloses a method for extracting natural fibre from straws, wheat straws and eulaliopsis binata under an anaerobic condition. The method comprises the following steps of: drying the straws, the wheat straws and the eulaliopsis binata till dry; cutting, depithing and hammering to form thick filament; placing the thick filament in an anaerobic fermentation tank to ferment; taking outthe thick filament from the anaerobic fermentation tank; cleaning and draining the thick filament; and crushing the thick filament through a hammer type depithing machine so as to form thin filament,namely a natural fibre product. The whole process has the advantages of low investment, low energy consumption, no pollution and easy operation. Meanwhile, two green products of natural fibre and combustible gas (methane) can be obtained. The method is a low-carbon production technology.

Description

technical field [0001] The invention relates to a method for extracting plant fibers, in particular to a method for extracting natural fibers from herbs mainly consisting of traditional agricultural waste. Background technique [0002] Straw (straw), wheat straw (haulm), and straw (alpine rush) are the draft straws of traditional agriculture after harvesting rice and wheat. Pollution, the current environmental protection policy has banned the burning of manuscript stalks, and its way out has become an urgent problem to be solved. Asparagus (grass) is a wild plant with high fiber content that grows widely on hillsides in hilly areas and has not been fully utilized. [0003] The above-mentioned herbaceous plants are rich in natural fibers and can be used. For example, wheat straw (haulm) has always been an important raw material for papermaking. [0004] Before the present invention was made, "Biogas Ecological Agriculture Technology" edited by Yuan Ruihua (the first edition...
