[0001] The invention relates to the technical field of reed bamboo particle production, and in particular to a method for processing super reed bamboo into higher performance particle materials. Background Art

[0002] Biomass resources are the fourth largest clean energy in the world in terms of reserves. They have broad development prospects. They are renewable, green and environmentally friendly, and widely distributed. Vigorously developing biomass resources has become a general trend and the direction of national conditions. As a high-yield, high-calorific value biomass resource, super reed has been increasingly recognized. Super reed pellets are one of the important ways to develop biomass energy. Among the existing biomass pelleting technologies, the most commonly used is the additive-free pelleting technology, which is to crush and dry the biomass raw materials to the appropriate moisture content, and then directly send them to the pellet machine to produce original ecological pellets without adding any additives in the middle.

[0003] However, due to the characteristics of the raw materials themselves, the product particles still have low calorific value and coking during use as gasifier charge, and the thermal stability is insufficient, making it difficult to meet the gasifier's requirements for charge stability at high temperatures. The pretreatment process is complicated, and there are too many types of raw materials and additives, which increases the difficulty of the production process, places higher requirements on measurement, and it is difficult to adjust product performance by changing the dosage of a certain additive.

[0004] In view of the above situation, in order to overcome the above technical problems, the present invention designs a method for processing super reed bamboo into higher performance pellets, which solves the above technical problems. Summary of the invention

[0005] The technical purpose to be achieved by the present invention is to design a method for processing super reed bamboo into higher performance pellets, and add different proportions of high-temperature binders and petroleum coke after the reed bamboo crushed material is dried, so as to improve the quality of the pellets and diversify the products, and meet different usage requirements.

[0006] In order to achieve the above technical objectives, the present invention provides the following technical solutions:

[0007] A method for processing super reed bamboo into higher performance pellets, the method comprising the following steps:

[0008] Step 1: The bales of reed bamboo are placed closely on the feeding conveyor, which conveys the bales of reed bamboo to the shredder. The speed of the conveyor is controlled by frequency conversion to achieve material balance between the shredder and the feeding conveyor. The shredder crushes the bales to within 70mm, and the crushed materials are conveyed to the screw feeder of the crusher through the discharging conveyor. The crushed materials output by the crusher are sent to the dryer;

[0009] Step 2: The dryer dries the wet powder with a moisture content of 25%-30% after crushing to a moisture content of 12%-15%. According to the characteristics of the raw materials, a drum dryer matching the capacity is selected, and the motor is steplessly regulated through the frequency converter to meet the production requirements of different speeds during production;

[0010] Step 3: Take super Phyllostachys arundinaceus biomass fragments and high-temperature binder, mix the two materials evenly using a proportioning scheme, and then send them to a pellet machine;

[0011] Step 4: The mixed raw materials are fed to the pellet machine through the feeding auger and automatically variable frequency, and pressed into pellets with a diameter of 7-8mm. The pellet machine is cooled by clean circulating water.

[0012] Preferably, one of the ratio schemes of step three is: adding 65 parts of high-temperature adhesive to every 1000 parts of super reed raw materials, wherein the high-temperature adhesive is an environmentally friendly adhesive with good thermal stability and adhesion, which can effectively maintain the particle shape at high temperature and enhance the heat resistance of the particles.

[0013] Preferably, the second ratio scheme of step three is: to every 900 parts of super reed raw materials, 58.5 parts of high-temperature binder and 100 parts of petroleum coke are added. The petroleum coke significantly improves the energy density of the particles by working together with the high-temperature binder, and is suitable for fuel uses with high energy efficiency requirements.

[0014] Preferably, the third ratio scheme of the three steps is: to every 800 parts of super reed raw materials, add 52 parts of high-temperature binder and 200 parts of petroleum coke, the added amount of petroleum coke and the ratio of the binder produce higher calorific value and combustion performance, which is suitable for the production needs of high calorific value fuel.

[0015] Preferably, the high temperature binder in step three is set to be a starch binder, a natural resin binder, a polymer binder, or a mixed material of the above three materials in any proportion.

[0016] Preferably, the feeding conveyor is a belt conveyor, which can automatically adjust the conveying rate according to the load of the shredder, thereby ensuring that the material is continuously and evenly fed into the shredder. The speed of the feeding conveyor is adjusted by a frequency conversion controller to adapt to the fluidity changes of different batches of raw materials.

[0017] Preferably, the pulverizer is a double-hammer crusher, which uses high-efficiency pulverizing blades to reduce energy consumption and equipment wear while ensuring high output. The feed port of the pulverizer is provided with an automatic screening device to remove unsuitable impurities, thereby ensuring the quality of the pulverized material.

[0018] Preferably, the dryer is a drum dryer, which adopts a multi-stage heating method to improve thermal efficiency and uniform drying effect. It can quickly reduce the moisture content of the wet powder without affecting the quality of the particles. The dryer is equipped with temperature and humidity sensors to adjust the working parameters in real time to ensure drying accuracy.

[0019] Preferably, when the speed of the motor is adjusted by a frequency converter, the frequency converter can be automatically adjusted according to the feedback signal of the temperature sensor in the dryer to ensure the stability and energy efficiency of the dryer operation under different humidity conditions.

[0020] Preferably, the feeding auger of the pellet machine is controlled by a frequency converter to achieve accurate and continuous material supply to ensure uniformity and stability of pellet formation. The speed of the feeding auger can be adjusted in real time according to the load of the pellet machine to ensure high efficiency and stability of the production process.

[0021] The beneficial effects of the present invention are as follows:

[0022] (1) The present invention firstly breaks up the whole bundle of super reed into smaller pieces. Then, the pieces are dried to remove excess water and ensure the smooth progress of subsequent processes. A high-temperature binder is added to the dried pieces, which helps to improve the bonding force between the pieces, thereby enhancing the stability of the particles. Finally, the pieces containing the binder are processed into particles through a certain processing technology for subsequent use or storage. This method effectively improves the stability of the shape of the particles during use by using a high-temperature binder and optimizing the process steps.

[0023] (2) The present invention breaks up the whole bundle of super reed bamboo into smaller pieces. The pieces are dried to remove moisture and ensure that the pieces are suitable for further processing. Petroleum coke is added to the pieces, and this additive can significantly increase the calorific value of the particles. Petroleum coke is a high-energy carbonaceous material that can enhance the combustion calorific value of the particles. The addition of petroleum coke not only increases the calorific value of the particles, but also effectively reduces the coking phenomenon during the combustion process, optimizes the combustion efficiency, and reduces the generation of pollutants.

[0024] (3) The present invention makes the super reed pellets have better combustion performance and stability by adding petroleum coke, and solves the problem that traditional biomass fuels are easy to coke during the combustion process. It can not only enhance the molding stability of the pellets, but also improve the calorific value of the pellets and reduce the coking phenomenon during the combustion process, thereby achieving multiple effects. Through the action of the high-temperature binder, the pellets are more stable during production, transportation and use. The addition of petroleum coke increases the calorific value of the pellets and improves the combustion efficiency. The use of petroleum coke also effectively avoids the problem that traditional biomass fuels are easy to coke during the combustion process. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] In order to more clearly illustrate the specific implementation methods of the present invention or the technical solutions in the prior art, the drawings required for use in the specific implementation methods or the description of the prior art will be briefly introduced below. Obviously, the drawings described below are some implementation methods of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative work.

[0026] The above and other aspects of the present invention will now be described, by way of example only, with reference to the accompanying drawings, in which:

[0027] Figure 1 It is a schematic flow chart of the method of the present invention. DETAILED DESCRIPTION

[0028] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0029] like Figure 1 As shown, a method for processing super reed bamboo into higher performance pellets, the steps of the method are as follows:

[0030] Step 1: The bales of reed bamboo are placed closely on the feeding conveyor, which conveys the bales of reed bamboo to the shredder. The speed of the conveyor is controlled by frequency conversion to achieve material balance between the shredder and the feeding conveyor. The shredder crushes the bales to within 70mm, and the crushed materials are conveyed to the screw feeder of the crusher through the discharging conveyor. The crushed materials output by the crusher are sent to the dryer;

[0031] Step 2: The dryer dries the wet powder with a moisture content of 25%-30% after crushing to a moisture content of 12%-15%. According to the characteristics of the raw materials, a drum dryer matching the capacity is selected, and the motor is steplessly regulated through the frequency converter to meet the production requirements of different speeds during production;

[0032] Step 3: Take super Phyllostachys arundinaceus biomass fragments and high-temperature binder, mix the two materials evenly using a proportioning scheme, and then send them to a pellet machine;

[0033] Step 4: The mixed raw materials are fed to the pellet machine through the feeding auger and automatically variable frequency, and pressed into pellets with a diameter of 7-8mm. The pellet machine is cooled by clean circulating water.

[0034] One of the three ratio schemes in the steps is: add 65 parts of high-temperature binder to every 1,000 parts of super reed raw materials. In this scheme, the selected high-temperature binder has good thermal stability and excellent bonding performance, can effectively maintain the shape of the particles under high temperature conditions, and enhance the heat resistance of the particles. This environmentally friendly binder not only provides excellent bonding effect, but also can continue to exert its performance at high temperatures, avoiding the phenomenon of softening or cracking of the particles in a high temperature environment, thereby ensuring the stability and use effect of the particles.

[0035] The selection of high-temperature binder is a crucial link in the entire ratio scheme. Traditional binders are easy to decompose or lose their bonding strength at high temperatures, while this environmentally friendly high-temperature binder can exist stably at high temperatures and maintain a high bonding effect. This feature allows the particles formed under high temperature conditions to maintain their shape more stably. Even after a long period of high-temperature combustion, the particles can still maintain their structure and prevent them from breaking or falling off. Especially in some equipment that requires high-temperature processing or use, the role of this high-temperature binder is more prominent.

[0036] In addition, another important advantage of the environmentally friendly high-temperature binder is its environmentally friendly characteristics. During use, this binder will not release harmful gases or cause pollution to the environment, which meets modern environmental protection requirements. With the improvement of people's awareness of environmental protection, the use of environmentally friendly binders can effectively reduce the emission of harmful substances and meet the needs of sustainable development. Therefore, this high-temperature binder not only improves the performance of the particles, but is also environmentally friendly and has broad application prospects.

[0037] Specifically for the application of the present invention, the processing process of the super reed raw material greatly enhances the molding stability of the particles by adding a high-temperature binder. This not only helps to increase the calorific value of the particles, but also effectively reduces the coking phenomenon during the combustion process, further improving the combustion efficiency. In some high-temperature application scenarios, such as gasifiers and other equipment, the particles with the addition of high-temperature binders show better heat resistance and stability, and can maintain stable operation for a long time in a high-temperature environment, improve the operating conditions of the equipment, and reduce maintenance costs.

[0038] In summary, the ratio scheme not only ensures the stability and heat resistance of particle forming by accurately controlling the addition amount of high-temperature binder, but also fully considers environmental protection, so that the invention can play an important role in improving the calorific value of particles, optimizing combustion effects, reducing coking phenomena, etc. At the same time, the application of this environmentally friendly binder is in line with the green development trend of today's industrial and energy fields, and helps promote the realization of sustainable energy utilization.

[0039] The second of the three mixing ratios in the step is: adding 58.5 parts of high temperature binder and 100 parts of petroleum coke to every 900 parts of super reed raw material. The core of this mixing ratio is that the energy density of the pellets is significantly improved through the combined effect of petroleum coke and high temperature binder, making it more suitable for fuel use with high energy efficiency requirements.

[0040] Petroleum coke is a high-energy carbonaceous material with a high calorific value. Adding petroleum coke to super reed raw materials can not only effectively increase the overall energy density of the particles, but also improve the combustion performance of the particles, increase the calorific value of the fuel, and release more energy during use. This is especially important for application scenarios that require high-efficiency fuels, such as industrial boilers, gasifiers and other equipment. By increasing the proportion of petroleum coke, the combustion efficiency of the fuel can be effectively improved, energy waste can be reduced, and thermal energy utilization can be improved.

[0041] In addition, the combination of petroleum coke and high-temperature binders can also prevent the particles from over-expanding or breaking during high-temperature combustion. High-temperature binders provide good bonding strength under high-temperature conditions, which helps the particles maintain a stable shape under high-temperature conditions, thereby reducing the occurrence of coking and further optimizing the combustion process. This ratio scheme not only meets the demand for high-efficiency fuel, but also improves the stability and high-temperature resistance of the particles, and has significant industrial application value.

[0042] The third of the three proportioning schemes in the step is: add 52 parts of high temperature binder and 200 parts of petroleum coke to every 800 parts of super reed raw material. In this proportioning scheme, the proportion of the amount of petroleum coke added and the high temperature binder is precisely designed to produce higher calorific value and better combustion performance, which is particularly suitable for production occasions that require high calorific value fuel.

[0043] As a carbonaceous material, petroleum coke has a very high calorific value. By increasing the proportion of petroleum coke, the overall energy density of the particles can be significantly increased, thereby improving the calorific value and combustion efficiency of the fuel. Compared with super reed raw materials, the high energy components provided by petroleum coke can greatly increase the energy release of the fuel during use, meeting some industrial applications with high energy efficiency requirements. Whether in industrial boilers, power plants or gasifiers and other equipment that require high calorific value fuels, this high calorific value particle can fully play its role, improve overall energy utilization efficiency and reduce energy waste.

[0044] In addition, the added high-temperature binder can ensure the stability and formability of the particles under high temperature conditions. The binder maintains a good bonding effect at high temperatures, preventing the particles from breaking or disintegrating during the combustion process, further optimizing the combustion effect and reducing coking. The interaction between petroleum coke and the binder not only improves the high-temperature resistance of the particles, but also ensures that the fuel can release energy efficiently and stably under high-temperature combustion conditions, thereby meeting the production needs of high-calorific value fuels.

[0045] This ratio scheme not only improves the calorific value and combustion performance of the particles, but also enhances the stability of the particles, making them an ideal high-efficiency fuel material and adapting to the increasing demand of modern industry for efficient and environmentally friendly fuels.

[0046] The high temperature adhesive in step 3 is set to be a starch adhesive, a natural resin adhesive, a polymer adhesive, or a mixture of any proportion of the above three materials. These adhesives have different characteristics and advantages, and can be reasonably selected and proportioned according to specific needs to achieve the best bonding effect.

[0047] Starch adhesives are usually derived from natural plants and have good biodegradability and environmental protection. They can provide effective bonding under high temperature conditions and are relatively inexpensive, making them a common environmentally friendly adhesive.

[0048] Natural resin binders have strong heat resistance and durability, and can work stably for a long time in high temperature environments. Resin binders can provide excellent structural stability to prevent particles from breaking or softening during the combustion process.

[0049] Polymer binders have strong bonding and stability, and are particularly suitable for applications that require high particle morphology and stability. They usually have good heat resistance and oxidation resistance, and can maintain their bonding strength in high temperature environments.

[0050] Through the reasonable combination of these three binders, a more stable and efficient bonding effect can be provided under different conditions of use, ensuring that the particles show better stability and high temperature resistance during processing and use.

[0051] The feeding conveyor adopts a belt conveyor, which has a reasonable design and simple structure, and can efficiently and stably complete the material conveying task. The belt conveyor transports the material from the silo or stacking area to the shredder through the conveyor belt, and can automatically adjust the conveying rate according to the load of the shredder. This automatic adjustment function greatly improves the adaptability of the system, allowing the material to continuously and evenly enter the shredder, ensuring that the shredder operates under the optimal load, thereby avoiding overload or shutdown, and improving the efficiency and stability of the entire production process.

[0052] In order to adapt to the changes in the fluidity of different batches of raw materials, the speed of the feed conveyor is adjusted by the frequency conversion controller. The frequency conversion controller can accurately control the speed of the conveyor according to the real-time feedback of the material fluidity and the load of the shredder, thereby adjusting the material conveying speed to ensure that the material can maintain an appropriate conveying rate at any time. In this way, the conveying rate can be flexibly adjusted according to the characteristics of the material (such as humidity, particle size, etc.), ensuring that the material will not be blocked or the flow rate is too fast, and ensuring the smooth operation of the entire production line.

[0053] Belt conveyors not only have strong load adaptability, but also good wear resistance and service life, and are suitable for continuous transportation of large quantities of materials. Compared with other transportation methods, belt conveyors can effectively reduce material loss and improve transportation efficiency. Its flexibility and adjustability enable it to be widely used in occasions with different material types and production requirements, especially in industrial processes that require efficient and stable material transportation, playing an important role.

[0054] In addition, the design of the belt conveyor is easy to maintain and service, and the operator can finely adjust the speed of the conveyor according to actual needs to ensure that the equipment is always in the best working condition. In summary, the belt conveyor provides a continuous and stable material supply for the entire production process with its automatic adjustment rate, flexibility and high efficiency, ensuring the smooth operation of the shredder and the improvement of production efficiency.

[0055] The pulverizer is a double-hammer crusher, which uses advanced technology and efficient crushing blades, and can reduce energy consumption and equipment wear while achieving efficient crushing. The design of the double-hammer crusher combines the characteristics of high output and low energy consumption, effectively reducing the operating cost of the equipment while ensuring production efficiency. The crushing blades have been specially treated to have higher hardness and wear resistance, which not only improves the crushing efficiency but also extends the service life of the equipment. Compared with traditional crushers, the double-hammer crusher can reduce energy waste during operation and improve the material processing capacity per unit time.

[0056] In order to further improve the quality of crushed materials, the feed port of the crusher is equipped with an automatic screening device. This device can automatically screen out unsuitable impurities, such as metal particles, stones and other hard materials before the materials enter the crusher, to prevent these impurities from damaging the blades and crushing chamber. The automatic screening device can also automatically adjust the screening parameters according to the different characteristics of the materials to ensure that only materials suitable for crushing are fed into the crusher, thereby improving production efficiency and product purity.

[0057] This double hammer crusher can not only efficiently complete the material crushing task, but also reduce energy consumption and equipment maintenance requirements through optimized design. It is particularly suitable for industrial applications that require efficient processing of large quantities of materials. The addition of an automatic screening device effectively improves the quality of the crushed material and the consistency of the product, ensuring the stability and reliability of the entire production process.

[0058] The dryer is a drum dryer, which is an efficient material drying equipment and is widely used in the drying process of various wet powder materials. The drum design allows the material to fully contact with the hot air during the rotation process, thereby improving the heat exchange efficiency and ensuring that the material can be heated evenly. The dryer adopts a multi-stage heating method, which gradually heats the material so that it can be dried layer by layer in different temperature sections, greatly improving the overall thermal efficiency. In each heating zone, the temperature and air flow can be precisely controlled to ensure that the material can be heated evenly during the drying process, thereby obtaining a uniform drying effect.

[0059] While ensuring efficient drying, the dryer pays special attention to not affecting the quality of the pellets, especially when quickly reducing the moisture content of the wet powder, to avoid damage or performance degradation of the pellets caused by overheating. The installation of humidity and temperature sensors makes the entire drying process more intelligent. These sensors monitor the temperature and humidity changes inside the dryer in real time, and automatically feed back data to the control system. The system automatically adjusts the working parameters such as heating temperature and wind speed based on real-time data to ensure that the temperature and humidity changes can be accurately controlled under different materials and drying stages, and the drying effect is optimized.

[0060] This precise control method ensures the drying accuracy, avoids the problem of over-drying or uneven humidity of materials caused by improper operation, improves the drying efficiency and ensures the stability of product quality. In addition, the multi-stage heating design and intelligent control system of the dryer make it more adaptable to the drying needs of different materials, and has the characteristics of high efficiency, energy saving and adjustability.

[0061] The motor speed is adjusted by the frequency converter to adapt to the operation requirements of the dryer under different working conditions. As an intelligent regulating device, the frequency converter can automatically adjust the speed of the motor according to the feedback signal of the temperature sensor inside the dryer, so as to accurately control the heat output and air volume regulation during the drying process. When the humidity of the material in the dryer is high, the system will automatically increase the speed, increase the flow of hot air and heating efficiency to ensure that the material is dried quickly; when the humidity is low, the frequency converter will appropriately reduce the speed to avoid overheating, thereby saving energy and maintaining the quality of the material.

[0062] This adjustment mechanism ensures the stability and energy efficiency of the dryer under different humidity conditions, avoiding energy waste and uneven drying caused by humidity fluctuations. Through the intelligent collaboration of temperature sensors and inverters, the dryer can not only provide continuous and uniform heat, but also maintain high efficiency of drying effects while saving energy. This intelligent adjustment system significantly improves the automation level of the equipment and improves the efficiency and stability of the entire drying process.

[0063] The feeding auger of the pellet machine is controlled by a frequency converter to achieve accurate and continuous material supply to ensure the uniformity and stability of pellet formation. As an important part of the pellet machine, the feeding auger is responsible for continuously and stably transporting the raw materials to the pellet forming area. In the pellet production process, the material supply speed directly affects the quality and production efficiency of the pellets. By using a frequency converter to adjust the speed of the feeding auger, the material supply amount can be accurately controlled according to actual needs, thereby ensuring the uniformity and stability of the pellets, avoiding the supply of too much or too little material, and ensuring that the pellet machine can achieve the best production state when working.

[0064] The speed of the feeding auger can be adjusted in real time according to the load of the pellet machine. When the load of the pellet machine is high, the inverter will automatically increase the speed of the feeding auger to ensure sufficient material supply and ensure that the pellet machine can operate continuously and stably; when the load is low, the inverter will reduce the speed in time to avoid excessive material supply and reduce unnecessary energy consumption. Through this intelligent adjustment, the feeding auger can always maintain a stable feed rate under different working conditions, effectively improving the efficiency of the production process.

[0065] In addition, the use of frequency converters makes the entire production process more flexible and adjustable. When production needs change, operators can easily adjust the speed of the feeding auger through the frequency converter to adapt to the fluidity of different batches of materials and changes in the pellet machine load. By accurately controlling the feed amount, not only can the pellet molding quality be improved, but also the wear and energy consumption of the equipment can be reduced, thereby extending the service life of the equipment and reducing maintenance costs.

[0066] In summary, the frequency converter's precise control of the feeding auger speed makes the pellet production process more efficient, stable and intelligent. Whether in producing high-quality pellets or improving production efficiency, the application of frequency converters plays a vital role.
