Description

Technical Field

[0001] The present invention relates to the technical field of biomass raw material processing, and in particular to a method and system for recycling biomass raw materials. Background Art

[0002] Countries around the world have invented and manufactured various types of treatment equipment for biomass raw materials and wastes such as inferior food, expired food, distiller's grains and bean dregs, peeled (such as tangerine peel and other medicinal and edible products) pulp and pomace or peel, tail vegetables, medicinal residues, extraction residues and straw produced by food processing plants, beverage and juice plants, medicinal material processing plants, breweries, bean product plants, sugar factories, and pre-prepared food plants, as well as activated sludge, restaurant kitchen (leftover) garbage, human and livestock manure, crop straw and other types of biomass organic waste and non-organic waste from large and medium-sized supermarkets in cities, communities, villages, factories, farms, and sewage treatment plants. However, existing equipment or methods mostly use incineration or fermentation methods and equipment with biological microbial strains for treatment.

[0003] For example, at room temperature or at a temperature of 60°C, or even at 80°C-90°C for a short time, or as disclosed in patent CN114437833A, a carbonization reactor is used for gasification reaction to achieve the treatment of biomass or its waste.

[0004] However, the main problem with these current methods is that they are difficult to achieve good resource utilization results. Incineration or fermentation still produces or is accompanied by a large amount of garbage, which requires secondary or even multiple treatments such as landfill or incineration. During the treatment process, there are a large amount of greenhouse gases, harmful gases, and harmful substances such as odor or odor, which pollute the ecological environment such as the atmosphere, water, and soil. The gasification reaction process consumes a lot of energy, and the process is complicated, costly, and harmful. Some technical processes consume a lot of energy and have great limitations in adapting to scenarios.

[0005] At present, the industry is in urgent need of methods and equipment systems that can solve the above-mentioned problems, especially methods and equipment systems that can be conveniently used in various scenarios where the demand for biomass raw material resource utilization needs to be solved nearby or on-site. Summary of the invention

[0006] In view of this, the purpose of the present invention is to propose a method and system for the resource recycling of biomass raw materials, which has low energy consumption and high resource utilization rate and is applicable to a wide range of scenarios.

[0007] Based on the above purpose, the present invention provides a method for recycling biomass raw materials, the method comprising:

[0008] The raw biomass raw material is heated, and the heated biomass raw material is subjected to a biochemical reaction and / or a synthesis reaction according to a preset processing condition to obtain a primary resource product of the biomass raw material;

[0009] After the primary resource product is subjected to cyclic shear filtration and / or ultrasonic enhanced dispersion, the primary resource product is converted into a secondary resource product;

[0010] The secondary resource product includes a biomass solid part and a biomass liquid part; the biomass solid part is returned to the biochemical reaction step, and the biomass liquid part is ready for loading or is ready for loading after being concentrated.

[0011] Based on another purpose of the present invention, when the primary resource product is subjected to cyclic shear filtration and / or ultrasonic enhanced dispersion, some filter residue is generated which does not enter the next step. The filter residue is returned to the biochemical reaction and / or synthesis step according to preset processing conditions for further processing.

[0012] Based on another object of the present invention, it also includes a heat recovery step:

[0013] The heat generated or carried by the biochemical reaction and / or synthesis reaction stage, the circulating shear filtration and / or ultrasonic enhanced dispersion stage and the evaporation concentration stage is recycled and utilized, and heat energy is provided to the heating stage, the biochemical reaction and / or synthesis reaction stage through a heat exchange equipment system.

[0014] Based on another object of the present invention, it also includes:

[0015] Screening and classifying the original biomass raw materials to obtain screening and classification results;

[0016] When the heated biomass raw material is subjected to a biochemical reaction or a synthesis reaction according to a preset processing condition, adding elements and components matching the classification result according to the classification result;

[0017] When the biomass liquid portion is concentrated and ready for packaging, the biomass liquid portion is transported to a finished product line for packaging according to the elements and components that match the classification results.

[0018] Based on another object of the present invention, when the original biomass raw material includes biomass water-containing material, the original biomass raw material of this type is subjected to the steps of removing impurities, crushing and beating to transform it into biomass water-containing raw material with a certain water content;

[0019] At this time, when the biomass water-containing raw materials enter the biochemical synthesis reaction tank for biochemical reaction, the temperature of the external heat pump and / or the heating device is controlled at 70°C-130°C, the heating reaction temperature of the biochemical synthesis reaction tank is controlled at 70°C-150°C, the air heat pump is pressurized, the pressure is controlled at 0.5Mpa-1Mpa, and the reaction time is controlled at 0.5h-4h.

[0020] In a second aspect, the present invention further provides a biomass raw material resource recycling system, comprising:

[0021] Original biomass material storage tank, heating subsystem, pressurizing subsystem, biochemical synthesis reaction tank, stirring subsystem, quantitative batching equipment, composite reaction tank, circulating shear filtration and ultrasonic linkage unit, filter residue tank, filtrate tank, concentration equipment, waste hot water storage tank and upper control unit connected to the communication;

[0022] The heating subsystem heats the water-containing biomass material in a cycle and then transports it to the biochemical synthesis reaction tank. The temperature of the heating by the external heat pump and / or the heating device is controlled at 70°C-130°C. The batching equipment quantitatively transports the biochemical promoter and inorganic macro-, medium- and trace element additives through pipeline pumps and valves into the biomass raw material tank or the biochemical synthesis reaction tank or the composite reaction tank, respectively, and the stirring subsystem preset in the tank performs variable speed stirring or gradient stirring reaction.

[0023] The heating device in the biochemical synthesis reaction tank is started to continue heating to the set temperature, and the air heat pump is started to pressurize to the set pressure. After reaching the preset processing conditions including the set temperature, pressure and reaction time, the discharge valve of the biochemical synthesis reaction tank is opened to discharge the primary resource product formed after the treatment to the composite reaction tank through the pressure pipeline;

[0024] The discharge valve is connected to the feed port of the circulating shear filtration linkage unit, and the discharge port is connected to the feed port of the composite reaction tank through a pipeline valve. After the circulating shear filtration and ultrasonic enhanced dispersion are completed, the primary resource product is converted into a secondary resource product, and the solid part of the biomass filter residue in the secondary resource product enters the filter residue tank and returns to be mixed with the new batch of original biomass raw materials for reprocessing;

[0025] The biomass liquid part in the secondary resource product enters the filtrate tank and is directly loaded as a finished product according to product needs, or is transported to a concentration device for concentration;

[0026] The heat of the materials in the biochemical synthesis reaction tank and the composite reaction tank, as well as the residual heat of the materials after concentration, are recovered and utilized. The concentrated liquid after concentration is automatically transported to the concentrated liquid tank to be loaded as a finished product.

[0027] From the above description, it can be seen that the resource recycling method and system for biomass raw materials provided by the present invention have a scientific and reasonable treatment process method, and the entire process processing time is short. Generally, a batch of original biomass raw materials can be processed at one time in 4-8 hours (6 hours on average), and no polluting gas, wastewater or waste residue is generated. Different types of biomass are classified and processed to produce different resource utilization results, with high resource efficiency and good resource benefits. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] Through the action of "circulating shear filtration and ultrasonic linkage unit" in the device, new small molecule organic products of micro-nano size are further self-assembled to improve the application effect, which can be summarized as biochemical synthesis resource utilization.

[0037] The resource recycling method and system of biomass raw materials of the present invention are suitable for scenarios where biomass raw materials need to be processed or reprocessed. After a series of steps, the various types of resource results finally produced can be put into use with low energy consumption and short time.

[0038] In a feasible implementation manner of the exemplary embodiment of the present invention, in combination with Figure 1 As shown, the resource recycling method of the biomass raw material comprises the following steps:

[0039] In step 110, after the original biomass raw material is heated, the heated biomass raw material is subjected to a biochemical reaction or a synthesis reaction according to a preset processing condition to obtain a primary resource product of the biomass raw material;

[0040] Biomass raw materials are used as the original materials in the process method or system device of the present invention, and their types are wide, for example: secondary products of food processing plants, raw materials and residues of animal and plant medicinal materials, leftover vegetables and fruits from fruit and vegetable processing, residues left over from fruit processing into juice in juice factories, discarded fresh fruit pulp, shells and peels, vegetable residues and vegetable residues from processing vegetables into vegetable juice, rice bran residues produced by grain processing plants while processing grains, fresh residues from vermicelli processing, starch processing, and cassava processing, protein-containing powder residues. Fresh protein powder from starch processing plants, fresh bean dregs left over from soy product processing, lees from wineries, fermentation liquid produced by organic acid and alcohol fermentation. Waste residues and sludge from processing products with plants as raw materials, biomass residues from pharmaceutical factories, restaurant (waste) garbage, activated sludge, human and livestock manure, crop straw and forestry residues such as sawdust, leaves, branches, and waste substrates for culturing biological bacteria, and other biomass raw materials or their waste materials;

[0041] The biochemical catalytic hydrolysis reaction in the biochemical synthesis reactor in the device is generally called biochemistry, and the dynamic self-assembly synthesis of new small molecule organic complexes with multiple inorganic macro-, medium- and trace elements is generally called synthesis.

[0042] The preset processing conditions of the original biomass raw material include: setting the original water-containing material to be heated to 70°C-130°C in the heating stage, mixing the biochemical promoter and inorganic macro-, medium- and trace elements with the primary resource product in the biochemical reaction stage, and controlling the pH value of the biochemical reaction tank to 2-4, and the reaction conditions of the biochemical reaction tank are 70°C-150°C, 0.5Mpa-1Mpa, and the reaction time is controlled to be 0.5h-4h;

[0043] In step 120, the primary resource product is subjected to cyclic shear filtration and / or ultrasonic enhanced dispersion to transform the primary resource product into a secondary resource product;

[0044] In a feasible implementation of the exemplary embodiment of the present invention, the primary resource product may be: biomass water-containing materials including food factory processing products or sludge in biomass organic waste, biomass medicine residues of pharmaceutical factories, fresh lees of liquor factories, fresh fruit residues, fresh vinegar residues, fresh vegetable residues that can be reused in the food industry, fresh bean residues of bean products factories, waste vegetables and fruits of fruit and vegetable factories, restaurant kitchen (waste) garbage, human, livestock, poultry manure, crop straw, forestry waste sawdust, leaves, etc., in a heated state of at least one or a mixture of two or more thereof. The water-containing materials of the above-mentioned biomass raw materials or their wastes are removed from impurities, crushed and pulped into materials with a water content of about 80% as biomass water-containing raw materials.

[0045] The secondary resource products may be: biomass resource utilization is based on the different types of biomass raw materials, the different elements and components added, which can be made into fertilizers, feeds, beverages, fruit juices, vegetable juices, bean juices and other basic raw materials. After further disinfection, evaporation, filtration and other steps, the final product for the consumer market can be obtained, such as small molecule organic water-soluble fertilizers, small molecule organic water-soluble feeds, small molecule water-soluble beverages, fruit juices, vegetable juices, bean juices and other foods and health products.

[0046] In step 130, the secondary resource product includes a biomass solid portion and a biomass liquid portion; the biomass solid portion is returned to the biochemical reaction step, and the biomass liquid portion is directly packaged or concentrated and then packaged in liquid form or granulated according to product requirements.

[0047] In a feasible implementation of an exemplary embodiment of the present invention, the solid part of the biomass is the filter residue, and the liquid part of the biomass is the filtrate, which is packaged in a suitable form according to the classification results when concentrated and ready for packaging.

[0048] In some scenarios of the exemplary embodiments of the present invention, the liquid portion of the biomass can be used directly without evaporation and concentration, that is, evaporation and concentration can be determined according to specific scenarios, which will be explained below with reference to examples.

[0049] Combination Figure 2 The structural schematic diagram of the resource recycling system of biomass raw materials of the present invention is shown, which is a combined equipment system of a complete set of devices, including a biomass water-containing material tank 1, a biochemical synthesis reaction tank 2, a heat exchange heating pump as a first heating subsystem 2-1, a heater as a second heating subsystem 2-2, a quantitative batching device as a quantitative batching subsystem 2-3, a composite reaction tank 3, a circulating shear filtration ultrasonic linkage unit 4, a filter residue tank 4-1, a filtrate tank 4-2, a concentration device as an evaporation concentration 5, a waste heat storage tank 6, various types of small molecule concentrate storage tanks 7, and an upper control unit.

[0050] The upper control unit controls the control logic of each subsystem or equipment in the processing process: the control unit uses the intelligent electrical control system to control the data of temperature sensors, pressure sensors, weighing sensors, mass sensors, liquid level sensors, particle size sensors, viscosity sensors, pH sensors and other data installed in various parts of each equipment or subsystem, and performs production control according to preset production requirements such as time, temperature, pressure, speed, ingredients, moisture content, pH value, particle size, reaction mode, stirring mode, and finished product packaging.

[0051] Based on another purpose of the present invention, when the primary resource product is subjected to cyclic shear filtration and ultrasonic enhanced dispersion, some filter residue is generated which does not enter the next step. The filter residue is returned to the biochemical reaction step according to preset processing conditions for further processing.

[0052] Based on another object of the present invention, it also includes a heat recovery step:

[0053] The heat generated in the biochemical reaction stage, the composite reaction stage and the evaporation concentration stage is recovered, and the heat exchange subsystem is used to circulate heat energy to the heating stage and the biochemical reaction stage.

[0054] Based on another object of the present invention, it also includes:

[0055] Classifying the original biomass raw material to obtain a classification result;

[0056] When the heated biomass raw material is subjected to a biochemical reaction or a synthesis reaction according to a preset processing condition, adding elements and components matching the classification result according to the classification result;

[0057] When the biomass liquid portion is concentrated and ready for packaging, the biomass liquid portion is transported to a finished product line for packaging according to the elements and components that match the classification results.

[0058] Based on another object of the present invention, when the original biomass raw material includes biomass water-containing material, the original biomass raw material of this type is subjected to the steps of removing impurities, crushing and pulping to transform it into biomass water-containing raw material with a certain water content;

[0059] At this time, when the biomass water-containing raw materials enter the biochemical synthesis reaction tank for biochemical reaction, the temperature of the external heat pump heating is controlled at 70°C-130°C, the heating temperature of the biochemical synthesis reaction tank is controlled at 70°C-150°C, the air heat pump is pressurized, the pressure is controlled at 0.5Mpa-1Mpa, and the reaction time is controlled at 0.5h-4h.

[0060] The method of the present invention takes an average of about 6 hours to process a batch of raw materials, which is short in time and consumes less energy, and there is no odor or greenhouse gas emission in the whole process.

[0061] According to different biomass types, we produce small molecule organic fertilizers, small molecule organic feeds, small molecule fruit and vegetable beverages, nutritional health products and other products, achieving high-value and high-efficiency resource utilization.

[0062] It can achieve the recycling treatment of waste hot water and filter residue without generating any waste water or waste residue.

[0063] The temperature range controlled in the process of the present invention is that the external heat pump and / or heating device controls the heating temperature, which is generally 70°C-130°C. "Secondary heating" means that the heat pump heats the biomass water-containing material to 70°C-150°C once, which saves more than 30% energy compared with conventional external steam heating; on the basis of the primary heating temperature of 70°C-130°C, the biochemical synthesis reaction tank is heated to 115°C-150°C for the second time, which belongs to the heating with a temperature difference of 20°C-45°C, which saves more than 30% energy compared with conventional external steam heating or electric heating. By implementing two heatings, the whole set of equipment system saves about 60% energy, and the energy-saving benefits are obvious. The devices that need to be driven by power in the combination of the above-mentioned whole set of devices are all intelligently controlled by intelligent control cabinets, saving human resources.

[0064] Under certain conditions, the above-mentioned secondary heating temperature is 115℃-130℃. However, in some more specific or preferred scenarios, the above-mentioned secondary heating temperature is selected to be heated to 150℃, which is more efficient, but the energy consumption is higher. Therefore, the more preferred scheme of the present invention is that the secondary heating temperature range is between 115℃-130℃, which can take into account both efficiency and energy consumption, and has better equipment investment.

[0065] The raw materials are quantitatively transported by batching equipment through pipeline pumps and valves to transport biochemical promoters and inorganic macro-, medium- and trace element additives into the raw biomass material storage tank or biochemical synthesis reaction tank or composite reaction tank, and are stirred and reacted by the variable speed function stirring device or gradient function stirring device installed in the tank.

[0066] In a feasible implementation of an exemplary embodiment of the present invention, the biomass water-containing material is preferably cyclically heated to 70°C-95°C by a 2-1 heat pump. After the heating is completed, the heated biomass water-containing material is transported to the feed inlet of the biochemical synthesis reaction tank 2 through a pipeline pump valve, and then the biochemical promoter and various large, medium and trace inorganic elements are quantitatively input into the feed inlet of the biochemical synthesis reaction tank 2 in sequence by a batching device 2-3. After the batching and feeding is completed, the feed inlet is closed, and the heater inside the biochemical synthesis reaction tank 2 is started to continue After heating to 115℃-150℃, turn off the heater, and then use the pressure pipe of the air heat pump 2-2 to pressurize the air inlet of the biochemical synthesis reaction tank 2 to 0.5Mpa-1Mpa, control the pressurized reaction time of the biochemical synthesis reaction tank 2 to be controlled at 0.5-4h, then open the discharge valve, and automatically transport to the feed port of the composite reaction tank 3 through the pipeline valve. After feeding, its discharge port is connected to the feed port of the circulating shear filtration ultrasonic linkage unit 4, and its discharge port is connected to the feed port of the composite reaction tank 4 for circulating shear filtration ultrasonic treatment. The number of revolutions of the circulation device is controlled at 3000 rpm-8000 rpm, and the filtration speed is controlled at 5m / h-30m / h.

[0067] The ultrasonic time of the circulating shear filtration is controlled at 0.5h-3h. Open the slag discharge valve of the filter device to discharge the filter residue to 4-1, and return the filter residue of 4-1 to mix with the new material for reprocessing. Open the liquid discharge valve of the filter device to discharge the filtrate to 4-2, and the discharge port of 4-2 is then transported to the feed port of 5 through the pipeline pump valve for feeding, and the known evaporation and concentration equipment is used for concentration, and the waste hot water enters 6, and the waste hot water is transported to the heating pump of 2-1 through the pipeline valve to heat the cold end for heat recovery. The concentrated liquid of the evaporation and concentration equipment 5 enters the concentrated liquid storage tank 7 to complete the production process. According to the type and properties of the biomass water-containing material, the ingredients, etc. and the different requirements of the finished product, it can be made into small molecule organic fertilizers, small molecule organic feeds, small molecule organic nutritional foods and health care beverages, etc.

[0068] Based on the same inventive concept, corresponding to any of the above-mentioned embodiments and methods, the present invention also provides a complete set of equipment system for recycling biomass raw materials, including:

[0069] Original biomass material storage tank, heating subsystem, pressurizing subsystem, biochemical synthesis reaction tank, stirring subsystem, quantitative batching equipment, composite reaction tank, circulating shear filtration ultrasonic linkage unit, filter residue tank, filtrate tank, concentration equipment, waste hot water storage tank and upper control unit connected to the communication;

[0070] The heating equipment is part of the heating subsystem, and the pressurizing equipment is part of the pressurizing subsystem.

[0071] The heating subsystem heats the water-containing biomass material in a cycle and then transports it to the biochemical synthesis reaction tank. The batching equipment quantitatively transports the biochemical promoter and inorganic macro-, medium- and trace element additives into the biochemical synthesis reaction tank through pipeline pumps and valves, and the stirring system in the tank stirs and reacts.

[0072] The heating device in the biochemical synthesis reaction tank is started to continue heating to the set temperature, and the air heat pump is started to pressurize to the set pressure. After reaching the preset processing conditions including the set temperature, pressure and reaction time, the discharge valve of the biochemical synthesis reaction tank is opened to discharge the primary resource products formed after the treatment to the composite reaction tank through the pressure pipeline at one time;

[0075] The discharge valve is connected to the feed port of the circulating shear filtration linkage unit, and the discharge port is connected to the feed port of the composite reaction tank through a pipeline valve. After the circulating shear filtration and ultrasonic enhanced dispersion are completed, the primary resource product is converted into a secondary resource product, and the biomass solid part in the secondary resource product enters the filter residue tank and returns to be mixed with the newly added original biomass raw material for reprocessing;

[0076] The biomass liquid part in the secondary resource product enters the filtrate tank and is transported to the concentration device for concentration;

[0077] The material heat in the biochemical reaction tank and the composite reaction tank, as well as the residual heat of the concentrated material, are recycled and utilized, and the concentrated liquid after concentration is automatically transported to the concentrated liquid tank to be loaded as a finished product.

[0078] According to different biomass raw materials, small molecule organic water-soluble fertilizers, small molecule organic liquid feeds, small molecule nutritional foods and health products can be made through a complete set of equipment systems for biomass biochemical synthesis.

[0079] The biomass raw material resource recycling system of the present invention includes the following specific embodiments:

[0080] Combination Figure 2 As shown, the water-containing material in the original biomass and its waste 1 is kitchen waste that has been purified through the well-known impurity removal, crushing, pulping, filtering and other purification processes to serve as the water-containing material in 1.

[0081] The heating subsystem 2-1 heats the biomass water-containing material 1, and stops heating when the temperature reaches 80°C.

[0082] The water-containing material heated to 80°C is transported to the feed port of 2. After the material is fed, the biochemical promoter and inorganic macro-, medium- and trace elements are quantitatively transported to the material inlet of 2 in sequence through 2-3. The amount of the biochemical promoter is based on the control of the material pH value of 2 in the biochemical synthesis reaction tank 2 as the standard, and the amount of the macro-, medium- and trace elements is based on the national standard control standard N+P2O5+K2O≥8%, organic matter≥10%, and trace elements (in terms of metal)≥2%. Small molecule organic fertilizers can be produced.

[0083] After all the materials in 2 are added, start the heater in 2 for heating, stop heating when the temperature reaches 120℃, start 2-2 for pressurization, and stop pressurizing when the pressure reaches 0.8Mpa. Stop pressurizing when the temperature in the tank is maintained at 120℃ and the pressure is 0.8Mpa. After maintaining for 2 hours, open the discharge port 2 after reducing the pressure through the pressure reducing valve, and automatically discharge the materials in 2 to the feed port in 3 at one time. The discharge port in 3 is connected to the feed port in 4 through a pipe, and the discharge port in 4 is connected to the feed port in 3 through a pipe for cyclic shearing and filtering. The number of revolutions of the circulating shearing machine in 4 is controlled at 6000 rpm, the circulating filtration speed is controlled at 10m / h, and the circulating shearing and filtration time is controlled at 2h. The ultrasonic frequency in 3 is controlled at 20 kHz, and the sound intensity is controlled at 10W / cm 2 .

[0084] After the cycle shearing process is completed, the filter residue from the filter in 4 is returned to be mixed with the new material for reprocessing, and the filtrate is transported by the pipeline pump valve to 5 for known evaporation concentration, and the excess hot water evaporated is transported from the outlet in 6 to the heat pump 2-1 through the pipeline pump valve to provide heat for the heat pump. The concentrated liquid in 6 enters 7 from the discharge port and becomes a small molecule organic fertilizer that meets the national standards.

[0085] The power required to drive the sub-equipment involved in the entire processing process is completed by the intelligent control cabinet under automatic control.

[0088] The heating subsystem 2-1 heats the biomass water-containing material 1, and stops heating when the temperature reaches 60°C.

[0089] The water-containing material heated to 60°C is transported to the feed port of 2. After the material is fed, the biochemical promoter is added through 2-3, and the amount is controlled according to the slurry pH value = 3. The feed port valve of 2 is closed, and the agitator of 2 is used to stir and mix evenly. The heater in 2 is started to heat the slurry in 2, and the temperature is maintained at 60°C. 2-2 is started to pressurize to 0.6Mpa and then the pressurization is stopped. The temperature and pressure are kept for 3 hours. After the pressure is reduced through the pressure reducing valve, the discharge port of 2 is opened, and the slurry in 2 is discharged to the feed port of 3 at one time for feeding.

[0090] The discharge port in 3 is connected to the feed port in 4 through a pipe, and the discharge port in 4 is connected to the feed port in 3 through a pipe, and a circulation shear filtration treatment is carried out. The circulation shear filtration time is controlled at 2.5 hours, the ultrasonic frequency in 3 is controlled at 25 kHz, the sound intensity is controlled at 8W / cm2, the speed of the circulation shearing machine in 5 is controlled at 5000 rpm, the circulation filtration speed is controlled at 15m / h, and the circulation shear filtration time is controlled at 2.5 hours.

[0091] After the cyclic shear filtration is completed, the filter residue 4-1 is returned and mixed with new material for reprocessing, and the filtrate 4-2 is transported to 5.

[0092] The slurry in 5 is subjected to known evaporation concentration, and the excess hot water from evaporation enters 6, and then enters the heat pump 2-1 from the drainage port of 6 through the pipeline pump valve to provide heat for the heat pump. The concentrated liquid in 5 enters 7, and is used as raw materials by fruit juice factories, vegetable juice factories, bean product factories and other manufacturers to process fruit residues, vegetable residues, and bean residues into raw materials of fruit juice, vegetable juice, and bean juice with micro-nano particles.

[0093] The power equipment involved in the entire processing process is automatically controlled by the intelligent control cabinet.

[0094] The biomass raw material resource recycling system of the present invention, in a more specific embodiment, also includes:

[0095] The water-containing material of the original biomass raw material 1 is fresh straw and fallen fruits in fruit cultivation, etc. After being removed from impurities, crushed and pulped, the slurry with a water content of about 90% becomes the water-containing material in 1.

[0096] The heating subsystem 2-1 heats the biomass water-containing material 1, and stops heating when the temperature reaches 75°C.

[0097] The water-containing material heated to 75°C is transported to the feed port of 2. After the material is added, the biochemical catalyst promoter is quantitatively added through 2-3, and the amount is controlled according to the slurry pH value = 2. The feed port valve of 2 is closed, and the agitator of 2 is used to stir and mix evenly. Then, the heater in 2 is started for heating. When the slurry temperature in 2 reaches 125°C, the heating is stopped. 2-2 is started for pressurization to 0.7Mpa, and the pressurization is stopped. The temperature and pressure are maintained for 2.5h. After the pressure is reduced through the pressure reducing valve, the discharge port of 2 is opened, and the slurry in 2 is discharged to the feed port of 3 at one time for feeding.

[0098] The discharge port in 3 is connected to the feed port in 4 through a pipe, and the discharge port in 4 is connected to the feed port in 3 through a pipe, and a circulation shear filtration treatment is carried out. The circulation shear filtration time is controlled at 2h, the ultrasonic frequency in 3 is controlled at 30 kHz, the sound intensity is controlled at 5W / cm2, the circulation shear machine speed in 5 is controlled at 4000 rpm, the circulation filtration speed is controlled at 30m / h, and the circulation shear filtration time is controlled at 3h.

[0099] After the cyclic shear filtration is completed, the filter residue is discharged through the discharge port 4-1 and returned to mix with the new material for cyclic treatment. The slurry dispersed by ultrasonic enhancement in 3 is transported from 4-2 to 5.

[0100] The slurry in 5 is evaporated and concentrated to a water content of 80%, and the excess hot water evaporated enters 6, and then enters the 2-1 heat pump through the pipeline pump valve from the drain port of 6 to provide heat for the heat pump. The concentrated liquid outlet in 5 automatically enters 7 as the energy raw material of the liquid pig feed, and sodium hydroxide is added to neutralize the pH value to 6, and a known preservative or a known lactic acid bacteria agent is added as the energy raw material of the liquid pig feed. The particles reach the micro-nano level, which is conducive to the rapid absorption of nutrients by pigs.

[0101] While the invention has been described in conjunction with specific embodiments thereof, many alternatives, modifications and variations of these embodiments will be apparent to those skilled in the art in light of the foregoing description.

[0102] The embodiments of the present invention are intended to cover all such substitutions, modifications and variations that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the embodiments of the present invention should be included in the protection scope of the present invention.
