Description
Technical Field
The invention provides a product collection and a preparation method which are particularly applicable to the cleaning process of mixed waste wood as a raw material, and relates to the clean resource recycling of the obtained waste wood or mixed waste wood or waste containing wood components and waste plastics collected from the current society, wherein the method comprises the steps of disassembly/construction in the construction industry, or/and resident decoration, or/and wood industry processing, or/and garden trimming and the like. The invention belongs to the field of comprehensive utilization of waste wood or waste plastic.
Background
Because of the extremely deficient wood of the main raw materials of pulping and papermaking in China, a great amount of waste wood or mixed waste wood discharged from the fields such as disassembly/construction of the building industry, resident decoration, wood industry processing, garden trimming and the like is utilized by some papermaking pulping enterprises with the advantages of approaching coastal regions, and the waste wood or mixed waste wood is used for pulping. However, since the water discharged from the last process of pulping by wood cannot be economically removed, even if the water is completely treated according to national standard emission standards of water pollutants in pulping and papermaking industry (GB 3544-2008), the treated clean water cannot be recycled infinitely, and cannot be used as agricultural irrigation water, but can be discharged into sea or injected into rivers capable of entering the sea, and the pulping water is required to be discharged into the sea or rivers capable of entering the sea, so that the water is limited by regions, and impurities such as COD organic matters in the pulping water which affects the water quality of the sea, the river and the water, are required to be treated according to the national standard (GB 3544-2008), and if the production capacity is not higher than the annual production scale of 10 ten thousand tons of pulp, the economic and social benefits are extremely concerned.
In inland areas without the advantages of offshore areas, a large amount of waste wood or mixed waste wood is concentrated in biomass fuel particles at present in a so-called recycling way, or the waste wood or mixed waste wood containing long fiber components is inappropriately used as a wood component in the preparation of wood-plastic composite particles.
At present, a great amount of waste wood or mixed waste wood discharged in the fields of disassembly/construction of building industry, resident decoration, wood industry processing, garden trimming and the like can be used for pulping or preparing similar new materials which can partially replace paper pulp, and finally, waste water with high inorganic salt content can not be discharged, besides the alkaline hydrogen peroxide pulping process in industry can have great progress compared with an alkaline method, but the water in the process is far away from the requirements of harmless field environment planting, and the requirements are: na contained in water + Or/and K+ or/and Mg 2+ The molar concentration of the sodium salt is less than or equal to 0.034mol/L, or/and the total concentration of the soluble inorganic sodium salt, potassium salt and magnesium salt in weight percent is less than or equal to 0.20 percent (weight percent) -the saline-alkali soil defines a threshold value; no bad exhaust gas such as ammonia is discharged; or no strict requirement of complicated operation of an enzyme method; the chemical auxiliary agent can be simple, low in cost, safe and effective; the circulating water in the process is less and is easy to be harmlessly treated or utilized; the ideal process requirement is not reported in the literature.
The long fibers and the pulverized fibers can be used for preparing the paper pulp, and the different requirements of the long fibers and the pulverized fibers can be reasonably connected into the resource utilization of the waste wood or the mixed waste wood; furthermore, the wood species in the waste wood or the mixed waste wood is extremely different, which is mainly represented by that the hydrophobic resin components and the content in various woods always have larger difference, and the waste wood or the mixed waste wood of the mixed wood species is used for preparing hydrophilic fibers which can be used in paper, and the fibers of the product are possibly uneven after the hot dipping procedure of aqueous solution; if the waste wood or the mixed waste wood is further provided with color impurities such as paint skin and the like, and the obtained fiber product to be used for paper is provided with defects of color dust, what is the hydrophilic fiber product with obvious defects is? No literature is reported on these questions and solutions.
For various impurities in the waste wood or the mixed waste wood, the method can be bypassed in a new process without environmental hindrance and at low cost, and a new technical scheme is needed.
In addition, in the wood-plastic industry at present, wood-plastic composite products are made of waste wood chips and plastics, and the preparation process of mixing and compounding fluffy wood chips and plastics is to use a rapid mixer to firstly coarsely mix and then use a high-torque low-rotation-speed heating extruder to firstly thermally extrude the waste wood chips and plastics mixture into most basic and large-volume wood-plastic composite particle standby materials, and the standby materials have a plurality of hidden technological defects; then the spare material is used, the formula is further adjusted according to the material requirement appointed by the customer of the specific small wood-plastic composite product, the 'large-volume wood-plastic composite particle spare material' is mixed with plastic-containing particles of modified materials such as auxiliary agents and the like, the mixture is led into an extruder used as the wood-plastic product, and finally the material is extruded by heat, cooled by a die opening or extruded by heat and injected into a shaping die, so that the wood-plastic composite product is obtained. The fluffy wood dust and the possibly fluffy waste plastic film in the wood-plastic composite product industry, especially the waste plastic film material also contains aluminum foil and other impurity components, and the process defects of high energy consumption, large pollution and the like exist when the fluffy wood dust and the possibly fluffy waste plastic film material are used for preparing the bulk wood-plastic composite particle spare material by mixed hot extrusion. The specific expression of the process defect is as follows: the handling and confusion in the industry today is that the bubble wood-plastic compound in the non-molten state is difficult to be introduced into the feed throat of a high torque screw extruder: the non-molten bubble wood-plastic mixture is hard pushed into the feed inlet of the screw extruder by a strong machine, so that the strong pole holding resistance of the non-molten bubble wood-plastic mixture to the screw of the extruder is encountered, and the problems of high energy consumption and low output exist; and the second is: when there are metal and other non-wood and non-plastic hard particle impurities in the material, or/and the waste plastic is wet material after washing, the air release or/and hot glue filtering process is adopted, and the smoke/fog of the air release and hot glue filtering operation is large, which not only results in high energy consumption of the fan for exhausting and eliminating smoke, but also causes high labor intensity of workers and great harm to human body. There is no literature report on improvement from the aspect of clean production on the process defect.
Disclosure of Invention
The purpose of the invention is that: aiming at the defects of the prior application technology of waste wood or mixed waste wood or waste containing wood components or waste plastics collected from the current society, which relates to the approaches including disassembly/construction in the building industry, or/and resident decoration, or/and wood processing, or/and garden trimming and the like, the invention provides a clean product collection and a preparation method which take waste wood fragments as raw materials. The main product in the product set is hydrophilic fluffed fiber, and the physical properties of the hydrophilic fluffed fiber can be at least partially or completely used for replacing the traditional regenerated paper pulp to be used as paper making or used as a raw material for further processing to prepare bleached paper pulp; one of the byproducts is lignin/resin mixture product, or/and the other is wood-plastic composite regenerated coarse grain product. Finally, the specific directional uses and the like are provided for the provided products, manufacturing methods, equipment and the like.
The conception of the invention is as follows:
1. provides a product collection and a preparation method thereof, which takes proper particle size matters of waste wood materials and the like as raw materials and obtains the product collection through cleaning process treatment.
2. The "waste wood" of concept 1, which relates to at least waste wood or mixed waste wood obtained by a construction process in demolition/construction, or/and resident decoration, or/and wood processing, or/and gardening pruning, or the like, or waste containing wood components.
3. The term "etc" as used in concept 1 relates at least to the use of "waste wood" with subsequent auxiliary raw materials, such as waste plastics collected from today's society, etc.
4. Concept 1, a "product set" comprising, in turn, at least: can partially or completely replace the hydrophilic defibering fiber product alpha for paper making of the recycled paper pulp of at least waste corrugated paper boxes, and the product beta which can be used as soil organic modifier or the like, or/and the wood-plastic composite recycled coarse grain product delta.
5. The hydrophilic defibering fiber product alpha of concept 4 for papermaking by partially or completely replacing recycled pulp of at least waste corrugated cardboard box type "At least three material characteristics are needed, one of which is: the water is not floated on the water surface, so that the hydrophilic defibering fiber can be sucked under the water surface by a pump when the water-making machine is used for papermaking, and the hydrophilic defibering fiber and the water are sprayed onto a wet-end blanket of the paper machine by a pump nozzle; and the second is: when the hydrophilic fluffing fiber is used in downstream paper-making enterprises, the phenomenon that water is dark brown like hot water tea leaves can not occur when the hydrophilic fluffing fiber is subjected to working conditions of higher than 70 ℃ and water contact through high-concentration grinding and the like; thirdly, the hydrophilic fluffing fiber contains Na in the water involved in the production process + Or/and K + Or/and Mg 2+ The molar ratio of the water to the volume of the water is less than or equal to 0.034mol/L, no harmful smell is emitted, and the auxiliary agent used does not contain or reduces substances which are hidden to be harmful to safe production, such as peroxide, and the like, namely, a strong oxidant or a strong reducing agent. The first characteristic is the threshold condition in downstream use, and the second characteristic and the third characteristic are red lines for ensuring environmental protection and safety in production and use.
6. The "waste wood material" and "suitable particle size" described in concept 1 are specifically contemplated as follows: because of the limitation of the 'environment-friendly red line' in the concept 5, the 'waste wood material' is seriously weakened by the permeability of the liquid in the hot water solution impregnation process to the solid, and the 'permeability of the liquid to the solid is seriously weakened by the compensation', the mode of increasing the surface area of the solid phase material of the wood is adopted to increase the surface area of the solid phase material of the wood by changing the mode that the wood chip adopted in the current wood pulping process for obtaining more long fibers is used for entering the alkali liquid into the process of changing the process of obtaining the waste wood long fiber into the process of obtaining the graded or mixed-particle-size waste wood long fiber fine-bundle-shaped fragments with any mesh size ranging from 3 meshes to 28 meshes at the expense of the yield of the long fibers.
7. Because of the limitation of the 'environment-friendly and safe red line' in the concept 5, the bifurcation of wood fibers is reduced, the surface roughness is reduced, the bonding force of the fibers which are wound or overlapped mutually like a nylon fastener tape in the application of papermaking and the like is reduced, or the fibers are not pinched at all, and the bonding force of the winding or the overlapping between the fibers is avoided; to solve the problem, the specific conception is as follows: the surface of the fiber is grafted by using water insoluble or indissolvable substances as whisker materials, but the amount of the whisker materials is strictly controlled within the range of less than or equal to 1 ～ 3 ～ 5 ～ 9 parts by weight per 100 parts by weight of hydrophilic defibering fiber absolute dry material, namely less than or equal to 1 part by weight or less than or equal to 3 parts by weight or less than or equal to 5 parts by weight or less than or equal to 9 parts by weight, so as to ensure the low ash requirement required by downstream application.
8. When the preparation of the hydrophilic fluffed fiber product alpha is nearly finished, or an auxiliary agent for masking iron/manganese ions is added, so that the product is not discolored and is more white; or adding common sterilizing and mildew-proof auxiliary agent with conventional amount in pulp preparation industry.
9. When preparing the "hydrophile defibering product α" of concept 4, the flow of brown/black liquor in the water is reversed to the flow of the "waste wood long fiber fine strand-like chip" of concept 6 to minimize the amount of water involved in delignification/resin removal; in the process for preparing the hydrophilic defibering fiber product alpha, the liquid-solid mixture is heated to a temperature of more than or equal to 70 ℃ for at least 2 times, and is subjected to solid-liquid separation once after each heating, and is subjected to solid-liquid separation for at least three times, so that the requirement of the second component in the concept 5 is met.
10. The byproduct materials obtained when the hydrophilic defibering fiber product alpha is prepared are fully utilized, and the products beta such as the soil organic modifier and the like described in the conception 4 are prepared by utilizing the brown/black liquor obtained when the hydrophilic defibering fiber product alpha is prepared, or/and at least another part of waste wood fragments is utilized: waste wood chips passing through a 28-mesh sieve are prepared into the delta-wood-plastic composite regenerated coarse grain product in the conception 4.
11. In order to ensure that the quality of the hydrophilic defibering fiber product alpha is convenient to identify, a calibration object with relatively constant hardness and fiber-to-fiber bonding force is provided, so that the quality of the product can be known by directly pinching/rubbing the calibration object and a detected sample; using conventional analytical methods, the ratio of the water-soluble organic content of the hot water leachate of the "brown/black liquor" and the "hydrophilically fluffed fiber product α" is defined.
12. The preparation of delta-wood-plastic composite regenerated coarse grain product in the conception 9 aims to solve the technical defects in the wood-plastic composite product industry along the way, namely: the bubble wood-plastic mixture in a non-molten state is difficult to be led into a feed inlet of a high-torque screw extruder, and when non-wood and non-plastic hard particle impurities such as metal exist in the material or/and the used waste plastic is a wet material after a water washing process, the problems of smoke/fog blending in the operations of air release and hot glue filtration, large discharge amount, high labor intensity, large harm to the body of operators and the like are difficult to be solved.

Example 6. A standard for comparison and a number of comparisons of this standard with the hydrophilically fluffed fibers a are presented with reference to fig. 9 to 12:
FIG. 9 is a photograph showing a dried mass sample obtained by picking up discharge feces of willow stems eaten by orchid planting lovers commonly called as willow manure, longhorn beetle larvae or wood moth larvae, sieving impurities coarser than 3 meshes and finer than 28 meshes in a laboratory, boiling to deactivate enzyme, kneading the dehydrated moisture material still containing 75% of water by hand, shaping the moisture material by hand in a disposable plastic cup, pouring out the plastic cup, and naturally drying the plastic cup at room temperature.
Fig. 10 is a black-and-white photograph of the "standard" of fig. 9, which is obtained from the ground pile under a willow in nature, and the white grass leaves on the root of the trunk of the willow in the photograph is "willow manure", and the true color of the willow manure is brown.
Fig. 11 is a black and white photograph of the "standard" of fig. 9 and 10, which is a true brown color, when collected in a laboratory, when not subjected to screening or the like.
The standard sample, commonly known as willow manure, as described in fig. 9-11 above, is a typical enzyme that has been digested and degraded by enzymes in the wood-eating worm digestive tract that break down cellulose/resin nutrients in wood; those skilled in the art are aware of: the wood fiber can be used for preparing paper pulp by an enzyme method; the dry mass standard shown in fig. 9 can be used to produce common kraft paper as is common in the market by simply beating the wet mass of the standard sample using a wood bar hammer as is used in ancient papermaking.
Because the inventor can use the standard sample as shown in fig. 9 under the condition of temporarily carrying out a plurality of quality tests on the paper-making test piece of the product, the following qualitative conclusion compared with the standard sample is given to the hydrophilic fluffing fiber alpha in the invention in a material comparison mode:
the surface hardness of the dried mass of the hydrophilic fluffed fiber alpha-1 shown in fig. 3 is lower than that of a standard sample, and after the dry mass is rubbed 10 times with the standard sample, the damaged missing amount of the two samples is compared, so that the following phenomenon can be seen: equivalent to the standard sample, or up to 5 times of the falling scraps of the standard sample;
The surface hardness of the dried mass of the hydrophilic fluffed fiber alpha-2 shown in fig. 4 is lower than that of the standard sample, and after the dry mass is rubbed 10 times with the standard sample, the damaged missing amount of the two samples is compared, so that the following phenomenon can be seen: comparable to the standard, or up to no more than 5 times the standard chip.
The comparison can be performed by observing with naked eyes as shown in fig. 12, which is a black-and-white photograph of the chip materials removed by the comparison between the sample in fig. 9 and the sample in fig. 4, wherein the brown long and thick fibers come from the sample in fig. 9, the gray short and thin fibers come from the sample in fig. 4, and the contact surfaces of the two contact surfaces should be selected to be smooth and compact when rubbing; better comparison, the weight loss of each of the two hands for rubbing comparison can be measured by a weight reduction method by using a balance. Of course, the standard sample of fig. 9 can be prepared, the fiber of the standard sample is more similar to the thickness and the agglomeration compactness of the detected sample, and the comparison result is more accurate.
Furthermore, the inventors have found that, even when "willow manure" is used as an enzyme seed in the preparation of a standard sample, an enzyme capable of decomposing lignin/resin in wood fibers is produced, and the enzyme preparation is used for treating the "waste wood particles" according to the present invention, which can achieve the same effect as the present invention in production water as well as the effect of not containing inorganic soluble salts in the water, but which reduces the amount of "brown/black liquor" as described in the item B in example 1-1 in example 1, in parts by weight W Brown/black liquor W is the weight part of absolute dry fiber with water content of less than 15% in the obtained main product alpha α At a ratio of W Brown/black liquor /W α "reduction, does not have features superior to the present invention; the process operation after the inoculation of the material with enzymes is significantly troublesome for the present invention, and the softening and milling operations for the fibers are not significantly reduced.
Using the dry bulk standard of example 6 as a quality test, if the standard is to be improved, the fibers of the standard may be subjected to a fine dispersion treatment to increase the strength of the standard; if the standard is to be lowered, the number of falling scraps and falling scraps of the standard sample is increased by not more than the number of falling scraps of the standard sample after the detected sample and the standard sample are rubbed for 10 times. In order to distinguish the color difference of the fallen scraps rubbed by the detected sample and the standard sample, the standard sample can be dyed by using color liquids such as blue ink and the like. The shape of the sample and the tested sample can break through the constraint of figures 3, 4 and 9, but the dry mass is relatively fair and reasonable when compared with the dry mass by pinching and rubbing, and the same or similar surface contact is adopted.
