Abstract
The present invention relates to the technique for producing fiber by corn straw with a method of vapor explosion and enzymes bacterium hydrolysis. Firstly, crushed corn straw and few catalyst are put into a vapor explosion tank for vapor explosion; the straw after the vapor explosion is put into a hydrolysis tank, and enzymolysis taking 1 to 3/1000 of the weight of the straw and water taking 4 to 8.5 times of the straw weight are added into the straw for hydrolyzing; the hydrolysate is dewatered and separated after the hydrolysis; the separated fibrin can produce straw short fiber by the regular technology processing. The method for producing the corn straw fibre has the advantages of no pollution in the overall process, no waste water emission, no waste gas emission, rich resources, broad prospect, and larger economical benefits and social benefit, all the side products in the production process can be processed and utilized, and waste can be changed into valuables.
Description
One, technical field:
The present invention relates to a kind of technology of utilizing the method for the quick-fried and enzyme bacterium hydrolysis of vapour with the corn stalk producd fibers.
Two, background technology:
Corn is the main crops of China, has produced a large amount of corn stalks simultaneously again, and except that small part obtained utilizing, major part had been caused very big pollution by on-site incineration to environment, and health of human body has been caused harm etc.
Three, summary of the invention:
The present invention is that corn stalk is quick-fried by vapour and the method hydrolysis of enzyme bacterium is produced broad-spectrum fiber.
It is quick-fried that corn stalk that at first will be through pulverizing and little amount of catalyst are put into steam-explosion jar vapour, straw after quick-fried is put into the water that hydrolytic decomposition pot adds 4～8.5 times of 1～3 ‰ complex enzyme of straw weight and stalk weight and is hydrolyzed with vapour again, after the hydrolysis, the hydrolysate dehydration is separated, and isolated cellulose can be produced the straw staple fibre after conventional PROCESS FOR TREATMENT.The part by weight of quick-fried straw of putting into of vapour and catalyst is 1: 0.001-0.0015, and the pressure when vapour is quick-fried is 1.7-1.9Mpa, the pressurized time of being heated is 7-8 minute.Complex enzyme used during hydrolysis consists of: cellulase 8500-15000; 1,4 beta-glucanase 100000-130000; Zytase 8000-12000; Carbohydrase 2000-3000; The sweet enzyme 4000-6000 of β glucose; Peroxidase 10000-1500.Temperature is between 45 ° of-60 ° of C during hydrolysis, hydrolysis time 20-60 minute.Take out the cellulose of bottom after the hydrolysis, after dehydration, again with producing the corn stalk staple fibre after the conventional treatment such as ozone and hydrogen peroxide bleaching, mixing, dissolving, spray silk.
Utilize this method production corn stalk fiber overall process pollution-free, no waste water and toxic emission, the byproduct in the production process also can be processed whole utilizations.Its aboundresources is turned waste into wealth, and has a extensive future, and has bigger economic benefit and social benefit.
Four, specific implementation method:
Example 1 at first is ground into dried corn stalk the pipe nipple about 3cm, sends in the steam-explosion jar, adds catalyst CaO by 1: 0.001 weight ratio of corn stalk simultaneously, and plus-pressure is to 1.7MPa, and it is quick-fried to stop carrying out after 7 minutes vapour.Straw with vapour after quick-fried is put into hydrolytic decomposition pot, and the weight ratio by corn stalk and water adds entry at 1: 4 again; Add complex enzyme, the weight ratio of corn stalk and complex enzyme is 1: 0.001; Be warmed to 45 ℃; Hydrolysis time 20 minutes.Corn stalk is lignin after the hydrolysis on the jar internal state is, the centre is a hemicellulose, and the bottom is a cellulose.The cellulose that will sink to the hydrolytic decomposition pot bottom is afterwards earlier emitted, again the cellulose of emitting is dewatered, use ozone and hydrogen peroxide bleaching, mixing, dissolving, filtration, de-bubble, spray silk again, washing, oven dry, curl, common process such as cut-out, packing, produce the corn stalk staple fibre.
Example 2: at first dried corn stalk is ground into the pipe nipple about 3cm, sends in the steam-explosion jar, add catalyst CaO by 1: 0.0013 weight ratio of corn stalk simultaneously, plus-pressure is to 1.8MPa, and it is quick-fried to stop carrying out after 7.5 minutes vapour.Straw with vapour after quick-fried is put into hydrolytic decomposition pot, and the weight ratio by corn stalk and water adds entry at 1: 6 again; Add complex enzyme, the weight ratio of corn stalk and complex enzyme is 1: 0.002; Be warmed to 50 ℃; Hydrolysis time 40 minutes.Corn stalk is lignin after the hydrolysis on the jar internal state is, the centre is a hemicellulose, and the bottom is a cellulose.The cellulose that will sink to the hydrolytic decomposition pot bottom is afterwards earlier emitted, again the cellulose of emitting is dewatered and use ozone and hydrogen peroxide bleaching, mixing, dissolving, filtration, de-bubble, spray silk again, washing, oven dry, curl, common process such as cut-out, packing, produce the corn stalk staple fibre.
Example 3: at first dried corn stalk is ground into the pipe nipple about 3cm, sends in the steam-explosion jar, add catalyst CaO2 by 1: 0.0015 weight ratio of corn stalk simultaneously, plus-pressure is to 1.9MPa, and it is quick-fried to stop carrying out after 8 minutes vapour.Straw with vapour after quick-fried is put into hydrolytic decomposition pot, and the weight ratio by corn stalk and water adds entry at 1: 8.5 again; Add complex enzyme, the weight ratio of corn stalk and complex enzyme is 1: 0.003; Be warmed to 60 ℃; Hydrolysis time 60 minutes.Corn stalk is lignin after the hydrolysis on the jar internal state is, the centre is a hemicellulose, and the bottom is a cellulose.The cellulose that will sink to the hydrolytic decomposition pot bottom is afterwards earlier emitted, again the cellulose of emitting is dewatered and use ozone and hydrogen peroxide bleaching, mixing, dissolving, filtration, de-bubble, spray silk again, washing, oven dry, curl, common process such as cut-out, packing, produce the corn stalk staple fibre.
