Abstract
The invention is a development of paper-making field. Its technique features are: Prepare paper-making materials. Use sap-pressing and thread-rolling machine to press sap of materials and knead them to fiber bundle. Add K-base hydrogen peroxide into curing reactor for curing. Add hydroxyl free radial and active oxygen formed by hydroxide in ion-membrane exchanger into photoelectric oxide complex reactor. With ultraviolet exposure and micro-electrolytic super chemical reaction, chromophoric group of lignin is broke to change its molecular structure and can bleach slurry. After fluffing by non-metal pressure refiner, slurry is prepared to high yield bleaching commodity without alkali, chlorine and pollution by devices of replacing, washing, screening and concentrating. Amount of K in waste water is 0.13%, which is taken as fertilizer source. Sediment is used to prepare 'K-base ecological carpet'.
Description
Technical field the present invention is the pioneering invention in paper-making pulping field.
Background technology tradition pulping process exists " seriously polluted ", " there is lack of raw materials " two big world property difficult problems, the pulping with ammonium sulfite method of rising in recent years, biological enzyme slurrying, Demolition Pulping also fail fundamentally to solve an above-mentioned difficult problem, " enclosed type cycle oxygenolysis pulping method " solved and polluted and a there is lack of raw materials difficult problem, but still exist " black liquor " to need to handle, exist the stalk sheet to screen in the slurry, the problem that water consumption increases and the sewage disposal time is long, cost is high still needs further to improve and even innovation.
Summary of the invention the technology of the present invention feature is with juice extracting and fibre rolling machine the juice in the raw material (as mulberry shoot, hybrid giant napier, sugar grass etc.) to be squeezed out to be used, and excess is crumpled into fibre bundle; Tow transport to the slaking reaction device, is added potassium base hydrogen peroxide oxidation, softening, slaking; In photoelectricity oxygen combined reaction device, add hydroxyl radical free radical and the active oxygen that hydroxide generates in the ionic membrane switch, under UV-irradiation and the senior chemical reaction of little electrolysis, abolish the chromophoric group of lignin selectively, thereby change the molecular structure of lignin, be retained in the slurry as " binder ", " filler "; After discongesting slurry with nonmetal pressure refiner, slurry is made the commodity bleached pulp with displacement washing, screening, enrichment facility; Contain potassium in the waste liquid (about 2 tons) and reach 0.13%, be used for making " potassium radical ecological blanket " (number of patent application: 2005100929983).
The specific embodiment 1, with small-sized branch silk machine various raw materials (rice wheat straw, mulberry shoot, cotton stalk, Chinese sorghum, cornstalk, bamboo chip, bagasse, reed, waste of flax, brush wood etc.) are resolved into crude fibre in the raw material concentrated area, remove earth, broken leaf simultaneously, foreign material about 10% are handled on the spot, and the pulp mill is transported in the crude fibre packing.
2, crude fibre is fully soaked into the back and juice is squeezed out, import source mill and make medicine, food or ethanol etc., excess is crumpled into fibre bundle be used for slurrying with juice extracting and fibre rolling machine.
3, with tow transport to the slaking reaction device, logical steam reaches 100 ℃ of insulations 30 minutes, adds surfactant, bleeding agent and with the potassium base hydrogen peroxide that hydroxide generates in the ionic membrane switch, makes that slurry softens, slaking.
4, the slurry after the slaking is delivered in the photoelectricity oxygen combined reaction device, add hydroxyl radical free radical and active oxygen that hydroxide generates in the ionic membrane switch, under the irradiation and the senior chemical reaction of little electrolysis of ultraviolet light, abolish the chromophoric group of lignin selectively with hydroxyl radical free radical and active oxygen, and then the molecular structure of change lignin, be retained in the slurry as " binder " and " filler ", pulp brightness reaches 60%ISO～90%ISO.
5, with nonmetal pressure refiner (as diamond, wear resistant resin etc.) slurry is discongested, eliminate slurry simultaneously and " return secretly " phenomenon.
6, with displacement washing, screening, enrichment facility slurry is washed (sand grains in the flush away slurry, calcareous etc.), screening (screening out the blade in the slurry, thick stalk etc.), be delivered to that disappearing dives after concentrating and disappear in the storehouse latent, make alkali-free, no chlorine, pollution-free, high yield, and have the bleaching commercial pulp of sterilization, deodorizing, anticorrosion air purification function.
7, the waste liquid that will concentrate in back waste liquid and the slaking reaction causes in the pond, is directly used in to irrigate or send into chemical fertilizer factory's making potassium base slow-release fertilizer.The liquid waste processing sediment is used for making " potassium radical ecological blanket " (number of patent application: 2005100929983).
