Description

Technical Field

[0001] This plan involves the field of solid waste resource utilization, specifically a cleaning product co-production method that fully utilizes miscellaneous waste plastics by graded utilization of all components and co-produces a variety of high-value-added cleaning products, achieving full green resource utilization of miscellaneous waste plastics. Background Art

[0002] With the continuous growth of global plastic consumption, the environmental load of miscellaneous waste plastics (such as waste plastic film, waste chemical fiber products, composite packaging materials, etc., specifically including waste chemical fiber carpets, waste plastic lawns, waste agricultural plastic film, waste foam plastics, waste plastic woven bags, waste / old plastic shoes, waste plastic geotextiles, miscellaneous waste plastic films discarded by the waste paper recycling industry, plastic floating objects fished from environmental water systems, miscellaneous plastic waste scraps discarded in the modern shoe industry process, miscellaneous waste chemical fibers and their fabrics or non-woven fabrics, waste plastic interior fabrics discarded from the inner walls of automobiles, miscellaneous plastic waste scraps discarded in the modern luggage industry process, miscellaneous waste plastic films discarded by the plastic-containing packaging and printing industry, etc.) is becoming increasingly severe. Traditional treatment methods (landfill, incineration) not only lead to soil / water pollution and the emission of toxic substances such as dioxins, but also cause serious waste of polymer resources and energy. The existing technology for the treatment of miscellaneous waste plastics generally has the following bottlenecks:

[0003] Low component utilization: Due to the difficulty of sorting mixed plastics, only high-purity components can be recycled into recycled plastic pellets, while low-value components such as waste plastics and low-calorific value solid waste are often directly discarded or inefficiently burned. For example, in the treatment of waste plastic film discarded by the waste paper recycling industry, not only is the recycling process hindered by the presence of large amounts of metal, but the wide variation in the plastic materials contained makes it difficult to stably control the quality of the recycled plastic pellets. Furthermore, the electricity consumption for producing one ton of recycled plastic pellets typically exceeds 1,500 kWh. Current processes only process the water-floating material obtained from flotation treatment, resulting in a recycled plastic pellet yield of only 40% of the total raw material, and the remaining water-sinking material is poorly disposed of.

[0004] Fragmentation of the process chain: Recycled plastic pellet production, biomass fuel preparation and ancillary resource recovery are mostly independent processes, lacking a synergistic co-production mechanism, resulting in high energy consumption and insufficient added value.

[0005] Poor environmental compatibility: Traditional pyrolysis and incineration processes rely on complex exhaust gas treatment systems, and fuel ash easily forms secondary solid waste, making it difficult to meet the modern circular economy's "zero landfill, full utilization" requirements. For example, fuel briquettes made from waste plastic film sediments discarded by the waste paper recycling industry generate large amounts of smoke when burned, increasing the workload of flue gas dust removal equipment.

[0006] Policy and market pressure: Driven by the global upgrade of the "plastic ban" and the "carbon neutrality" goal, there is an urgent need for a technical system that covers the utilization of all components of miscellaneous waste plastics and has both environmental and economic benefits to solve the industry pain points of "waste of high-value components and difficulty in handling low-value components". Summary of the Invention

[0007] In response to the above-mentioned situation, the present invention constructs a closed-loop chain of "resources-products-energy" for miscellaneous waste plastics through an innovative model of refined sorting-multi-path conversion-joint production synergy, which not only breaks through the limitations of traditional technologies on material components, but also realizes the essential transformation of waste from the "end of pollution" to the "starting point of recycling", which is in line with the national strategic emerging industries and green and low-carbon development orientation. Specifically, the present invention provides a method for the joint production of clean products with full green resource utilization of miscellaneous waste plastics. Through refined sorting, multi-path conversion and joint production synergy of miscellaneous waste plastics, zero landfill and full utilization of waste are achieved, and products such as recycled materials and clean fuels are produced, effectively building a low-carbon and environmentally friendly circular economy model.

[0008] Technical concept of the present invention:

[0009] In response to the dual challenges of global solid waste surge and resource shortage, a circular economy technology concept of "waste full component decomposition and cross-sector value reconstruction" is proposed. Its core lies in breaking through the traditional linear processing model and building a multi-dimensional and coordinated resource recycling system with a systems engineering mindset:

[0010] 1. Full component decomposition: Through multiple technologies such as physical sorting and chemical conversion, complex waste (such as miscellaneous plastic waste) is refined and separated into its components to identify the potential value of high-value resources (polymer materials), medium-value energy (biomass fuels) and low-value accessories (metals, wastewater);

[0011] 2. Cross-domain reconstruction: Directly channel the stripped components into multiple paths such as material recycling, energy production, and ancillary resource reuse, forming a three-dimensional co-production network of "resources-products-energy-by-products", and realizing the transformation of single waste into multi-form value carriers;

[0012] 3. System collaborative innovation: Through process chain coupling (such as the co-production of recycled plastic pellets and fuel preparation), equipment sharing (such as reusing old extruders), and energy cascade utilization (such as combustion heat recovery), a low-energy consumption, highly integrated collaborative production system is constructed to break through the fragmentation and inefficiency of traditional processes;

[0013] 4. Environmentally friendly orientation: With the goal of "zero landfill and zero secondary pollution," we minimize environmental impact through clean production processes (such as low-smoke combustion) and closed-loop resource utilization (such as wastewater reuse and ash feeding), while meeting stringent policy requirements for waste disposal.

[0014] 5. Economic model innovation: Through the value superposition effect of "one waste, multiple products", a cost-sharing and diversified revenue business model is constructed to improve the economic feasibility of waste treatment and promote the transformation of the industry from "environmental protection cost" to "circular economy industry".

[0015] The technical solution of this application is:

[0016] A method for the co-production of clean products with full green resource utilization of miscellaneous waste plastics, the co-production method at least includes a material sorting process, a recycled plastic pellet process and a waste biomass solid fuel process; in the material sorting process: if a wet process is adopted, water floating material and miscellaneous waste plastic solid waste A1 are obtained through crushing, magnetic separation / eddy current separation to remove metals, flotation separation, and dehydration, and wet sludge B1 is collected simultaneously; if a dry process is adopted, crushing, magnetic separation / eddy current separation to remove metals, air separation, and dehydration are carried out. / screening to obtain light products and mixed waste plastic solid waste A1, and simultaneously collect dry dust solid waste B2; the recycled plastic pellet process is: the sorted water floating material and / or light products are hot extruded through a sieve to remove impurities, and then water-cooled and pelletized to obtain recycled plastic pellets; the waste biomass solid fuel process is: the raw materials are crushed, dehydrated, mixed, and extruded to obtain solid fuel; in the waste biomass solid fuel process, the raw material ratio is calculated by weight as follows: mixed waste plastic solid waste A 20-40 parts; 10-20 parts of low calorific value solid waste B; 40-70 parts of low ash biomass solid waste C; the mixed plastic solid waste A includes the mixed plastic solid waste A1 obtained by the wet process and / or dry process in the material sorting process; the combustion calorific value of the low calorific value solid waste B ranges from 200 to 3000 kcal / kg, including wet sludge B1 and / or dry dust solid waste B2; the combustion calorific value of the low ash biomass solid waste C ranges from 3500 to 4800 kcal / kg.

[0017] Compared with the existing technology, the co-production method of the present invention sorts the plastic-containing waste materials, and the high-value components obtained by sorting are made into recycled plastic pellets, and the low-value components are made into a solid fuel with a combustion calorific value of 3500-4500 kcal / kg according to a specific raw material formula. This type of fuel emits less smoke when burned and will not increase the workload of the flue gas dust removal device. It can reduce solid waste combustion emissions while achieving 100% resource utilization of miscellaneous waste plastics and related solid wastes.

[0018] Furthermore, the co-production method also includes a composite material pelletizing process. This process involves mixing recycled plastic pellets with fiber reinforcement / powder filler according to a specific ratio, followed by extrusion and pelletization to produce fiber-reinforced / filler-modified composite material pellets. This increases the value of recycled plastics and improves economic efficiency.

[0019] Furthermore, the fiber reinforcement is plant fiber and / or waste textile fiber; the powder filler can be one or more of plant powder, inorganic powder, thermosetting resin powder, melamine resin waste product powder, and crushed waste polymer product dry distillation residue.

[0020] Furthermore, the raw materials of the composite material plastic pellets are group α raw materials or group β raw materials, or are a mixture of group α raw materials and group β raw materials; the components of group α raw materials and group β raw materials include, by weight:

[0021] Components Group α Raw Materials Group β Raw Materials

[0022] Recycled plastic pellets 20.0-24.5 parts; 65.5-70.0 parts;

[0023] Fiber reinforcement / powder filler 75.5-80.0 parts; 30.0-34.5 parts.

[0024] Furthermore, the components of the α group raw materials also include one or more of 0.5-8.0 parts by weight of epoxidized vegetable oil, 0.1-4.0 parts by weight of lubricant, and 0.1-2.0 parts by weight of antioxidant; the components of the β group raw materials also include one or more of 15.5-20.0 parts by weight of epoxidized vegetable oil, 4.5-5.5 parts by weight of lubricant, and 0.1-2.0 parts by weight of antioxidant.

[0025] Furthermore, in the waste-biomass solid fuel production process, the impure waste plastic solid waste A used includes the impure waste plastic solid waste A1 obtained in the material sorting process, and the slag discharged by the filter plate of the extruder head - the impure waste plastic solid waste A2 discharged when the screen plate is blocked due to failure to be screened during hot extrusion.

[0026] Furthermore, in the waste-biomass solid fuel production process, the low calorific value solid waste B used also includes low calorific value solid waste B3 in environmental waste.

[0027] Furthermore, in the waste biomass solid fuel production process, the low-ash biomass solid waste used includes one or more combinations of waste wood, cow dung, reed bamboo, locust, caragana, giant fungus grass, peanut shells, sugarcane bagasse, palm fruit bunches, agricultural straw, green space / garden waste rotten wood, pruning branches, fallen leaves, and grass tips;

[0028] Furthermore, in the process of producing the waste-containing biomass solid fuel, the raw materials also include cement, with the amount of cement equivalent to 3%-8% of the total amount of miscellaneous plastic solid waste A, low calorific value solid waste B, and low ash biomass solid waste C. Thus, a water-resistant waste-containing biomass solid fuel can be produced.

[0029] Furthermore, in the process of producing the waste biomass solid fuel, the raw materials are dehydrated to a moisture content of ≤30%.

[0030] In summary, the present invention has the following beneficial effects:

[0031] (1) Zero landfill: 100% resource utilization of miscellaneous plastic waste and related solid waste;

[0032] (2) Low carbon and energy saving: through material recycling and energy co-generation, reduce the energy consumption of traditional plastic recycling and fuel production;

[0033] (3) Economic diversification: A single raw material can be used to produce a variety of products to meet different market demands and enhance the risk resistance of the industrial chain;

[0034] (4) Environmental upgrade: Reduce plastic pollution and solid waste incineration emissions from the source, in line with the goals of circular economy and carbon neutrality. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0052] The present application is further described below with reference to the accompanying drawings and examples, but is not intended to limit the present application. In the following examples, any content not described in detail or not shown in detail in the accompanying drawings is common knowledge in the art.

[0053] When implementing the method for co-producing cleaning products for full green resource utilization of miscellaneous waste plastics of the present invention, the co-production of cleaning products may include the following:

[0054] First, recycled plastic pellets;

[0055] Second, fiber reinforcement / powder filler composite material granules;

[0056] Third, waste biomass solid fuel;

[0057] Fourth, one or more of recycled water, paper pulp, burned smokeless metals, self-produced hot steam, self-produced electricity, self-produced activated carbon, and self-produced charcoal;

[0058] The waste biomass solid fuel can be completely burned after being ignited and the ash does not form coke.

[0059] The physical products of the co-production relationship of recycled plastic pellets 2, fiber reinforcement / powder filler composite plastic pellets 3 and waste biomass solid fuel 4 are as follows: Figure 2 shown.

[0060] The sub-process of "recycled plastic pellets" involved in the present invention (see attached Figure 14 ), comprising the following series steps I to IV:

[0061] Step Ⅰ: Select waste plastic materials

[0062] Miscellaneous plastic waste that uses at least one or more of the following materials: waste chemical fiber carpets, waste plastic lawns, waste agricultural plastic films, waste foam plastics, waste plastic woven bags, waste / old plastic shoes, waste plastic geotextiles, miscellaneous waste plastic films discarded by the waste paper recycling industry, plastic floating objects fished from environmental water systems, miscellaneous waste plastic scraps discarded in the modern shoe manufacturing process, miscellaneous waste chemical fibers and their fabrics or non-woven fabrics, waste plastic interior fabrics discarded from the inner walls of automobiles, miscellaneous waste plastic scraps discarded in the modern luggage industry process, and miscellaneous waste plastic films discarded by the packaging and printing industry. Among these, the most difficult and most representative types are as follows: Figure 1 The waste plastic film 1 shown is discarded by the waste paper recycling industry.

[0063] Step II: Wet / Dry Sorting

[0064] Using the wet method: First, the material is crushed and subjected to magnetic / eddy current separation to remove metals, then subjected to circulating clean water flotation and washing, and the water-floating material with a high plastic content is scooped out and dehydrated to obtain intermediate material I. After water flotation in step II, the water-sinking material with a low plastic content can be directly scooped out and dehydrated by strong extrusion to a solid content in the range of 10% to 50% and an upper limit of the calorific value of combustion in the range of 3500 to 4500 kcal / kg, thereby obtaining the mixed plastic waste solid waste A1. The water used for flotation and washing is then subjected to flocculation, sedimentation, and filter pressing to obtain "low calorific value sludge" - wet process sludge B1, and the circulating clean water required in step II is also obtained.

[0065] Using the dry method: first crush the material, remove metals by magnetic / eddy current separation, and remove stone-like mechanical impurities by gravity separation; then screen: obtain the miscellaneous plastic waste light foam material with a higher plastic content from the sieve as intermediate material II, and obtain the miscellaneous plastic waste solid waste A1 with a lower plastic content from the sieve; or / and use wind separation: obtain the miscellaneous plastic waste light foam material with a higher plastic content as intermediate material II, and obtain the miscellaneous plastic waste solid waste A1 with a lower plastic content from the wind separation; and collect "low calorific value solid waste" - dry dust solid waste B2 - from the sieve, or / and wind dust removal machinery, or / and workshop;

[0066] Step III: Hot extrusion, sieving and granulation

[0067] The intermediate material I or / and the intermediate material II obtained in step II are introduced into a hot extrusion screw machine with a screen plate for hot screening and impurity removal. For the material that does not pass through the screen plate during hot extrusion, the die head residue discharged after the screen plate is blocked is collected - the impurity-containing waste plastic and solid waste A2;

[0068] Step IV: Water-cooled pelletizing

[0069] The hot melt plastic strips that have passed through the "screen plate of the hot extrusion screw machine" in step III and exited the hot extruder die are pulled through a water cooling trough to be rapidly cooled in isolation from air. The cooled plastic strips are then pelletized, stored, and packaged to obtain the finished product of recycled plastic pellets 2.

[0070] The sub-process of the "fiber reinforcement / powder filler composite material plastic pellets" involved in the present invention (see the attached Figure 14 ), comprising the following serial steps V to VII or and VIII:

[0071] Step V: Compounding the composite plastic pellets

[0072] According to the composition of the fiber reinforcement material / powder filler composite material plastic pellets, the composite material plastic pellets are used as a compounding material unit (m) to perform a mixing operation to obtain the intermediate material III for making the "fiber reinforcement material / powder filler composite material plastic pellets", which is the mixed material to be used for extrusion granulation;

[0073] Step VI: Extrusion granulation of mixed ingredients

[0074] The mixed material obtained in step V is extruded and granulated using the extrusion granulation unit (n) to obtain the intermediate material IV for preparing the "fiber reinforcement material / powder filler composite plastic pellets", that is, the granulated hot material to be air-cooled, and the temperature of the hot material after leaving the machine is controlled to be 110 to 180°C;

[0075] Step VII: Air cooling of hot granulated material

[0076] The hot granulated material to be air-cooled obtained in step VI is subjected to air-cooling treatment by using the air-cooling unit (o) to air-cool the intermediate material IV to obtain the finished product of the fiber reinforcement material / powder filler composite material plastic granule 3;

[0077] The sub-process of the "waste biomass solid fuel" involved in the present invention (see the attached Figure 14 ), comprising the following serial steps IX to XI:

[0078] Step IX: Prepare the materials

[0079] Source of solid waste A containing miscellaneous plastics:

[0080] (1) From the "wet flotation separation unit (c)", that is, from the wet method in step II: through water flotation, it can be directly collected from the submerged material with less plastic content, and after strong extrusion and dehydration to a solid content in the range of 10 to 50% and a combustion calorific value in the range of 3500 to 4500 kcal / kg, the collected solid waste A1 containing mixed plastics (such as Figure 3 shown);

[0081] (2) From the "dry-process sorting unit (d)", i.e., from the solid waste A1 with less plastic content obtained by the dry-process wind separation / screening process in step II;

[0082] (3) From the “hot extrusion granulation unit (f)”, that is, from “step III: hot extrusion and screening to remove impurities”, the head material residue that does not pass through the screen plate during hot extrusion and blocks the screen plate is discarded - the impurity-containing waste plastic solid waste A2 (such as Figure 4 shown);

[0083] Sources of low calorific value solid waste B:

[0084] (4) From the "wet flotation separator (c)", that is, from the "wet method" in step II, the low calorific value sludge B1 (such as Figure 5 shown);

[0085] (5) From the “dry process classifying unit (d)”, i.e., from the “dry process” in “step II”, the low calorific value solid waste collected from the screen, or / and the wind dust removal combined machine, or / and the workshop sweeping - dry process dust solid waste B2;

[0086] (6) The sewage purification sludge (such as Figure 6 any one or more of domestic waste, excrement, municipal sewage sludge, discarded Chinese patent medicine residues, waste mycelium discarded by the edible fungus industry, and combustible materials obtained by excavating and screening from landfills after fermentation, deodorization and sterilization;

[0087] Low ash biomass C sources:

[0088] The low-ash biomass C is derived from environmental waste and includes any one or more biomasses having a combustion calorific value in the range of 3500 to 4800 kcal / kg as described below:

[0089] Waste wood, cow dung, reed bamboo, acacia, caragana, giant fungus grass, peanut shells, sugarcane bagasse, palm fruit bunches, agricultural straw, and any one or more combinations of rotten wood, pruning branches, fallen leaves, and grass tips discarded in green spaces / gardens;

[0090] For the selected A, B, and C materials, the weight ratio W of the equilibrium moisture content of each material in the air is 15%. A :W B :W C =20-40:10-20:40-70, prepare the ingredients;

[0091] Step X: Pre-treatment of the materials

[0092] For the preparation of miscellaneous waste plastics A, the materials are first crushed into a size that does not block the granulation die hole, and then can be further removed by magnetic or / and eddy current separation;

[0093] For low calorific value solid waste B, if it involves malodorous biomass, it is first fermented to remove odor or toxins, and the moisture content is reduced to less than 50%. It is then crushed into chips / powders of a size that does not block the pelletizing die holes, and then can be subjected to magnetic and / or eddy current separation to further remove metals;

[0094] For low-ash biomass C preparation, first crush / finely grind it into crumbs / powdered material not coarser than meat floss, then use sun drying or / and mechanical drying to reduce the moisture content of the material to a level that does not affect granulation (generally the moisture content is controlled to be less than or equal to 20%).

[0095] Then, the weight ratio W of materials A, B, and C in the air is 15% of the equilibrium water content. A :W B :W C =20-40:10-20:40-70, make a mix;

[0096] Thus, the prepared material (such as Figure 8 If water resistance is required, you can add the equivalent of "W A +W B +W C " and 3-8% cement, whereby the product does not swell or disintegrate in room temperature water for at least 0.5 to 1 hour (e.g. Figure 15 As shown), the product can be placed in the open air for at least a short period of time;

[0097] Step Ⅺ: Press into strips

[0098] The prepared material "to be mechanically extruded" after pretreatment in step X is guided into a rotary roller extrusion granulation machine by a conveying machine. The fluffy mixed material of the ABC three-metal combination is extruded by the rotary roller in the granulation machine, and the fluffy material is strongly pressed into the hole die, thereby obtaining a columnar block or granular waste biomass solid fuel 4 (such as Figure 9 、 10 The combustion calorific value of the solid waste biomass fuel 4 is controlled by a formula to be within the range of 3500-5400 kcal / kg, thereby ensuring that the combustion has the characteristics of invisible smoke to the human eye.

[0099] The present invention also relates to an environmentally friendly treatment process, such as step VIII.

[0100] Step VIII: Remove the generated smoke dust in an environmentally friendly manner, specifically using a unit (p) that supports environmentally friendly smoke dust removal. For the workshop smoke dust generated in any of the processes of steps I-IV, V-VII, and IX-XI, the air is collected and diverted to a unit (p) that supports environmentally friendly smoke dust removal and is composed of at least cyclone separation, spray washing, spray liquid regeneration, and bag dust removal unit machinery to prevent the flying and diffusion of dust / smoke in the workshop.

[0101] As described above, steps I to IV, steps V to VIII, and steps IX to XI correspond to the three-stage process of "co-production" of "recycled plastic pellets" or / and "fiber reinforcement / powder filler composite plastic pellets" with "waste-included biomass fuel". When implementing the present invention, these three-stage process can be arranged in the same plot, independently executed by a single enterprise or collaboratively divided by multiple enterprises; the three-stage process can also be divided into sections and arranged in adjacent or similar plots within a driving distance of no more than 4 hours, independently implemented by a single enterprise or collaboratively implemented by multiple enterprises; in addition, the "waste plastic to recycled plastic pellets" process can also be set up in parallel at multiple locations, separately executed by one or more enterprises, and all connected in series with the "waste-included biomass fuel" process within a plot within a driving distance of no more than 4 hours, thereby realizing division of labor and cooperation among one or more enterprises.

[0102] The following is a further explanation of the three sub-processes.

[0103] 1. Recycled plastic pellets in the product portfolio

[0104] When implementing the present invention, the recycled plastic pellets are made from miscellaneous waste plastics as raw materials, and the water-floating material containing more miscellaneous waste plastics obtained by wet water separation is used as intermediate material I, or / and the light material containing more miscellaneous waste plastics obtained by dry air separation / screening is used as intermediate material II, and then further processed by hot extrusion. In one embodiment of the present invention, the miscellaneous waste plastics are used as follows Figure 1 The shown are waste plastic films discarded by the waste paper recycling industry.

[0105] like Figure 11 As shown, the sub-line A implementing the “recycled plastic pellets” process includes:

[0106] The coarse crushing process unit (a) is used to coarsely crush the mixed waste plastics in bales or bundles into loose pieces that can pass through a sieve with a square or circular hole diameter of 5 cm;

[0107] The magnetic / eddy-electric separator (b) is used to remove metal from the loose and crushed plastic waste.

[0108] The wet flotation separation unit (c) is used to wash and flot the loose and miscellaneous waste plastics that have been demetallized, and to separate the floating materials, sinking materials and bottom materials.

[0109] The dry material separation unit (d) is used to screen and winnow the loose and miscellaneous waste plastics from which metals have been removed, thereby separating the oversize material / light foam material with a high plastic content, the undersize material / heavy material with a slightly lower plastic content, and the undersize granular material / dust material with very little plastic content;

[0110] The extrusion dehydration treatment unit (e) is used to perform an extrusion dehydration process on the water-floating material that has been removed from the metal, washed, and flotated.

[0111] The hot extrusion granulation unit (f) is used to perform hot extrusion granulation on the water-floating material that has been subjected to metal removal, water washing, water flotation and dehydration treatments;

[0112] The collection, metering and packaging unit (g) is used to collect, meter and package the recycled plastic pellets that have undergone the overheated extrusion granulation process;

[0113] The dehydration treatment unit (h) is used to dehydrate the water-sunk material (containing miscellaneous plastic and solid waste A1) obtained after metal removal, water washing and water flotation.

[0114] The collection unit (i) is used to collect and process the bottom material after metal removal, water washing and water flotation.

[0115] The function of the reclaimed water purification unit (j) is to flocculate and purify the dirty reclaimed water separated after washing and water flotation, and obtain the purified reclaimed water for reuse and the low calorific value solid waste B1;

[0116] The dry distillation energy supply unit (k) is used to: Figure 14 As shown, the waste biomass solid fuel process ( Figure 14 The waste biomass solid fuel 4 or / and the water-resistant waste biomass solid fuel 4' obtained by the method (the dashed box and dashed arrow in the figure) is converted into electricity / heat 5 required in processes such as hot extrusion granulation, or produces marketable carbon or activated carbon 6;

[0117] Support for environmentally friendly mechanical devices (l), which at least include: for process machinery that produces noise and leaks water mist / smoke, these "process machinery" are equipped with standard container-type covers that can reduce noise, prevent water mist / smoke leaks, and facilitate the overall relocation of the "process machinery"; and a flue gas purification unit that purifies the exhaust gas collected by the pipeline in the "sub-line A" process and then discharges it after meeting the standards.

[0132] The unit (m) for compounding composite plastic pellets is used to mix the composite plastic pellet components in a proportional manner.

[0133] The function of the unit (n) for performing extrusion granulation on the mixed materials is to perform extrusion granulation on the materials after the mixing treatment in the unit (m) to obtain hot granular materials in the form of either strips or round particles. When implementing the present invention, the extruders that have been eliminated from the unit (f) for hot extrusion granulation and have suffered severe wear on the spiral teeth and the inner wall of the screw machine can be used to reassemble the unit.

[0134] The unit (o) for air cooling the hot granulated material has the function of air cooling the hot granulated material after the extrusion granulation treatment by the unit (n), so as to obtain fiber reinforced material / powder filler composite plastic pellets with high compressive resistance and non-fragile properties at room temperature.

[0136] 3. Waste biomass solid fuels in the product portfolio

[0137] The waste biomass solid fuel 4 of the present invention comprises:

[0138] Solid waste A containing miscellaneous plastics with a combustion calorific value of 3500 to 4500 kcal / kg, such as solid waste A1 containing miscellaneous plastics obtained by wet / dry separation of miscellaneous plastics (such as Figure 3 As shown), or / and the slag discharged by the filter plate of the extruder head - the waste plastic and solid waste A2 (such as Figure 4 shown);

[0139] Low calorific value solid waste B with a combustion calorific value of 200 to 3000 kcal / kg, such as sludge B1 obtained from the wet material selection process (such as Figure 5 As shown), by dry method to select granular dust solid waste B2, by low calorific value solid waste B3 in environmental garbage - such as the sewage purification sludge (such as the implementation of the present invention) of the enterprise Figure 6 as shown), as well as domestic garbage, excrement, municipal sewage purification sludge, medicinal residues discarded by the traditional Chinese medicine industry, waste mycelium discarded by the edible fungus industry, and combustibles obtained by excavating and screening from landfills after fermentation, deodorization and sterilization;

[0140] Low ash biomass C in environmental waste (such as Figure 7 (as shown) - at least a combination of any one or more of the following biomasses with a combustion calorific value within the range of 3500 to 4800 kcal / kg: waste wood, cow dung, reed bamboo, acacia, caragana, giant fungus grass, peanut shells, sugarcane bagasse, palm fruit bunches, agricultural straw, and rotten wood, pruning branches, fallen leaves, and grass tips discarded in green spaces / gardens.

[0141] By weight ratio W A :W B :W C =20-40:10-20:70-40 range to make three gold combinations. Figure 8 As shown, the beneficial qualities of the three-gold combination are: the combustion calorific value of the fuel is in the range of 3500 to 4500 kcal / kg, and no smoke is seen on the bare pellet flame ignited in ordinary air (see Figure 10 ash content is in the range of 15% to 20%.

[0142] like Figure 5 As shown, the sludge B1 is in the form of obvious pieces. When you open it by hand and look closely, you can see a lot of fibers. This is because the waste plastic used in the embodiment is Figure 1As shown, the waste plastic films discarded by the waste paper recycling industry result in the sludge B1 obtained from the purification of the "circulating water" containing a large amount of pulp fibers. This sludge can also be sold as low-quality pulp to paper mills as an auxiliary ingredient for papermaking.

[0143] like Figure 10 As shown, the flame of the solid fuel 4 containing recycled biomass fuel ignites in ordinary air without producing any smoke. This is because the total weight percentage of miscellaneous waste plastics in the three-metal combination of the present invention is between 40 and 70%, and the total combustion calorific value is controlled within the range of 3500-4500 kcal / kg. Within this range, the volatile organic matter ignited is always in excess of oxygen compared to the oxygen in the air. Therefore, it is inevitable that the flame will be smokeless when burning in a state of sufficient oxygen. However, the innovation of the present invention goes a step further, namely, co-producing the solid fuel 4 containing recycled biomass fuel with recycled pellets 2 made from miscellaneous waste plastics and / or with fiber reinforcement / powder filler composite pellets 3, thereby forming a combined product. This inherent innovation is that the solid fuel 4 containing recycled biomass fuel consumes all the solid waste generated by the recycled pellets 2 and / or with fiber reinforcement / powder filler composite pellets 3.

[0144] Sub-line C for implementing the waste biomass solid fuel production process, such as Figure 13 As shown, it includes at least the following series setting combinations (q) to (v):

[0145] The coarse crushing unit (q) is used to perform a coarse crushing process on low-ash biomass C in the form of bales or square bundles, loose branches, or wooden pillars with a diameter not exceeding 30 cm;

[0146] The unit for fine crushing (r) is used to crush the low-ash biomass C that has undergone the coarse crushing process into powder / crumbs in the form of meat floss, and to crush the low-ash biomass C until it passes through a sieve with a rectangular or circular aperture of 5 cm.

[0147] The mixing or fine crushing unit(s) is used to mix or finely crush A supplied from sub-line A, B1 / B2 supplied from sub-line A, or low calorific value solid waste B3 from environmental waste, and low ash biomass C from environmental waste, to prepare a three-metal combination material in a weight ratio of WA:WB:WC in the range of 20-40:10-20:40-70, into a meat floss-like powder / crumbs;

[0148] The fermentation and drying unit (t) is used to: process the aforementioned "mixed or finely pulverized meat floss powder / crumbs" and then subject them to aerobic fermentation / mechanical drying to further dehydrate them to a moisture content of no more than 30% for extrusion molding;

[0149] The extrusion molding process unit (U) is used to perform an extrusion molding operation on a mixture of powder / crumbs of meat floss having a weight ratio of WA:WB:WC = 20-40:10-20:70-40.

[0150] Support for environmentally friendly mechanical devices (v), which at least include: for process machinery that generates noise and leaks water mist / smoke, these "process machinery" are equipped with standard container-type covers that can reduce noise, prevent water mist / smoke leaks, and facilitate the overall relocation of the "process machinery"; and flue gas purification units that purify the exhaust gas collected by the pipeline and discharge it after meeting the standards.

[0151] IV. Varieties, qualities and uses of the product collection

[0152] The products and their varieties, quality, uses, etc. involved in the product set of the present invention include at least the following examples 4-1 to 4-2, or any one or more combinations of examples 4-3 to 4-8:

[0153] Example 4-1: The quality indicators of recycled plastic pellets shall at least include: no obvious foreign particles can be seen in the recycled plastic pellets by human eyes, and the surface of the recycled plastic pellets is shiny (such as Figure 2 It can be used in almost all plastic product fields that are non-food grade and do not require transparency or color restrictions, such as plastic boxes, plastic pipes, plastic basins, plastic plates, etc. as a new material to replace or partially replace plastics;

[0154] Example 4-2: Composition, quality indicators and uses of solid fuels made from waste biomass:

[0155] Assuming that the moisture content of each ingredient is ≤15%, the fuel is composed of the following solid wastes in proportion by weight: solid waste A containing impurities of waste plastics that are not suitable for granulation in the waste plastic recycling process: 20-40 parts; solid waste B with low calorific value from the recycled plastic pellet process or the environment: 10-20 parts; solid waste C with low ash content from the environment: 40-70 parts; and waste-containing biomass solid fuel 4 is obtained.

[0156] Or add the equivalent of "W A +W B +W C "A total of 3-8% cement is added to produce a water-resistant waste biomass solid fuel 4'.

[0157] Quality indicators:

[0158] Combustion calorific value: 3500-4500 kcal / kg;

[0159] Combustion performance: When the solid fuel product pellets are ignited in normal air, they can burn out to gray-white powdery ash, and there is no smoke visible to the naked eye (such as Figure 9For the waste solid fuel products bare particles, Figure 10 The flame of the waste solid fuel product is smokeless, or it can burn stably and smokelessly in a furnace equipped with at least two air inlet mechanisms (the furnace side wall has distributed air inlet holes);

[0160] Tail gas characteristics: The exhaust gas produced by combustion has the clean characteristics of smoke that is invisible to the naked eye before it is purified (such as Figure 10 (as shown: no smoke on the flame), or the exhaust gas after combustion in a stove equipped with at least two air inlet mechanisms and before entering the exhaust gas purification device has the clean characteristics of no smoke visible to the naked eye;

[0161] Water resistance: The water-resistant waste biomass solid fuel 4' does not disperse in room temperature water for at least 0.5 to 1 hour (see Figure 15 );

[0162] Application: Applicable to at least any silicate product that can incorporate fuel ash into its product formula, including cement, earth bricks, ceramsite, glazed ceramsite, foamed glazed ceramsite, and glass, as fuel in its firing production process; (Thus, heavy metal oxides implicit in the combustion ash of waste biomass solid fuel can be solidified therein without any worries.)

[0163] Example 4-3: For recycled water, the process requirements must include at least the following: using only polyferric sulfate or lime as a flocculant for purification; (Due to the flocculant restriction, the solid biomass fuel containing waste biomass can always contain the combustion-promoting oxidant catalyst - iron oxide, thereby avoiding the combustion coking problem similar to pure biomass pellet fuel - the formation of granular cinders after combustion, which cannot spontaneously combust and forms mosquito coil ash.)

[0164] Example 4-4: For recycled pulp, the process requirements include: filtering out light components from the water purification process; but not re-mixing the heavy sludge from the bottom of the sedimentation tank with high ash content;

[0165] Example 4-5: For burnt smokeless metals, the quality indicators or process requirements shall at least include: burnt metals in a furnace with a secondary air inlet mechanism, or mechanically retorted in a closed tank; such burnt smokeless metals can reduce smoke emissions during the subsequent hot melting process;

[0167] 1) Must meet the quality requirements for self-use or market;

[0168] 2) Hot steam is produced by: installing a furnace with two or more air inlet mechanisms; and operating in conjunction with auxiliary combined machinery for power generation, heat supply, or co-production of coal;

[0169] Example 4-7: For self-produced activated carbon, the quality index system or process requirements shall at least include: compliance with self-use or market quality requirements;

[0170] Example 4-8: For self-produced carbon, the quality index system or process requirements shall at least include: meeting the quality requirements for self-use or market.

[0171] Supplementary explanation: The present invention involves the "full green resource utilization of miscellaneous waste plastics", which specifically means: using the miscellaneous waste plastic solid waste A1 / A2 that is not suitable for granulation and is discarded in the miscellaneous waste plastic recycling process as an added component to increase the combustion calorific value, and the low calorific value solid waste B1 / B2 / B3 discarded in the synergistic recycling plastic pelletizing process are all recycled and co-produced into waste-containing biomass solid fuel.

[0172] The positive significance of the present invention is at least:

[0173] The present invention proposes a method for co-producing clean products with full green resource utilization of miscellaneous waste plastics. Its positive significance lies at least in that: in the collection of clean products, for the recycled plastic pellets made from miscellaneous waste plastics that will generate a large amount of solid waste, a waste-absorbing biomass solid fuel that can absorb a large amount of solid waste is provided to establish a co-production relationship with the recycled plastic pellets. Moreover, because the waste-absorbing biomass solid fuel has a broad market and huge usage of fuel energy, it can not only fully absorb the miscellaneous waste plastic-containing solid waste A1 / A2 that is not suitable for granulation and the low calorific value solid waste B1 / B2 discarded in the recycled plastic pellet process, but also can capture the low calorific value solid waste B3 in environmental waste and the low ash biomass solid waste C in environmental waste, with a weight ratio of W A :W B :W C = By combining the three elements in the range of 20-40:10-20:70-40, a more practical waste biomass solid fuel can be produced in a clean and co-produced manner.

[0174] By implementing the technical solution of this invention, not only has waste plastic been successfully recycled, but it has also achieved remarkable results in treating waste plastics containing high levels of impurities, mixed with paper, aluminum, thermoplastic elastomers, chemical fibers, fabrics, foam materials, or films. Previously, the recycling of such waste plastics often generated large amounts of solid waste. This has now not only resolved the processing challenges but also enabled the full utilization of waste plastic resources, demonstrating humanity's appreciation for and rational use of resources.

[0175] Specifically, we've proposed a technical solution for "a method for the co-production of clean products through the full, green resource utilization of mixed waste plastics." This not only represents an innovation in waste plastic recycling technology but also a commitment to environmental protection. This approach not only reduces waste plastic, particularly solid waste generated during the mixed waste plastic recycling process, but also enables resource recycling, saving energy and protecting the environment, achieving a true win-win situation for both economic and social benefits.

[0176] Of course, those skilled in the art will also make many modifications and improvements to the method for co-producing clean products by fully green resource utilization of miscellaneous waste plastics proposed in the present invention, such as adding combustion aids to the waste biomass fuel to improve its anti-coking properties during combustion, etc. The modification scheme of adding auxiliary agents does not break through the overall framework of the technical solution of the present invention and should all fall within the protection scope of the present invention.

[0177] The above general description of the invention and the description of its specific embodiments involved in this application should not be understood as limiting the technical solutions of the invention. Based on the disclosure of this application, those skilled in the art may, without violating the constituent elements of the invention involved, add, subtract, or combine the disclosed technical features in the above general description and / or specific embodiments (including examples) to form other technical solutions within the scope of protection of this application.
