Description

Technical Field

[0001] This utility model belongs to the field of organic solid waste resource utilization technology, and in particular relates to a horizontal rotary organic solid waste drying device. Background Technology

[0002] In the field of resource recovery from organic solid waste (such as biomass waste), the development of efficient drying technologies is crucial. Exploring the key factors affecting the efficiency of solid waste drying (such as temperature gradient, material mixing degree, and / or ventilation parameters) is a core step in achieving energy recovery and reducing the environmental footprint. However, existing laboratory drying devices generally use static trays or small fixed-bed reactors, which cannot meet this research requirement. At the same time, it is difficult to simulate the dynamic tumbling mixing and continuous heat transfer process of industrial horizontal vortex fermenters, resulting in significant deviations between experimental data and actual engineering applications (existing data show that the error can be as high as 15%-30%). This not only limits the accuracy of drying kinetic models but also hinders a deeper understanding of the mechanisms of solid waste reduction and heat recovery.

[0003] Traditional experimental methods for moisture measurement have serious shortcomings. Relying on the shutdown sampling oven method interrupts the continuity of the reaction and cannot capture the moisture evaporation curve in real time. The dynamic tumbling of the horizontal rotary fermenter further exacerbates the measurement challenge. Because the material is in a continuous tumbling state, the difficulty of moisture measurement is further increased, thus affecting the reliability and reproducibility of experimental data. In addition, air preheating is usually an important part of industrial equipment during the drying process, but existing laboratory equipment generally lacks corresponding controllable modules. Furthermore, the high cost of equipment further restricts experimental progress. Custom-made horizontal rotary devices on the market cost more than 4,000 yuan (mainly due to stainless steel materials, precision sensors, and transmission structures), while professional fermentation systems cost tens of thousands of yuan, far exceeding the budget of universities and small laboratories. This forces current researchers to rely on simplified devices, sacrificing the authenticity, accuracy, and comprehensiveness of the experiment. At the same time, the diversity of organic solid waste components and the dynamic interactions during the drying process (such as humidity fluctuations and particle agglomeration) cannot be fully simulated, which also limits the efficiency of the transition from laboratory to industrial scale-up.

[0004] In summary, there is currently no experimental device on the market that integrates a low-cost horizontal rotating structure, an efficient ventilation and preheating system, and real-time continuous and accurate weighing functions. Therefore, developing multifunctional, cost-effective, and accurate measurement equipment has become an urgent need to promote cutting-edge research and engineering optimization.

[0005] In summary, it is essential to provide a horizontal rotary organic solid waste drying device suitable for laboratory-scale simulation of the ventilation and thermal drying process of granular organic solid waste materials such as livestock and poultry manure (e.g., cow manure, pig manure) and sludge, as well as for precise measurement of moisture removal rate.

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] This utility model provides a horizontal rotary organic solid waste drying device, for example, such as... Figure 1 and Figure 2As shown, the horizontal rotary organic solid waste drying device includes: a horizontal rotary reactor (also referred to as a horizontal reactor) 2, a rotating platform 8 for driving the horizontal rotary reactor 2 to rotate, a preheating and ventilation system, and a weighing system (also referred to as a weighing device) 9 disposed below the rotating platform 8; the horizontal rotary reactor 2 is a cylindrical structure for containing organic solid waste 3, and short pipes extending from both ends (both ends in the axial direction) of the horizontal rotary reactor; in this utility model, the horizontal rotary reactor, as the core component of organic solid waste (e.g., wet organic solid waste material), is a cylindrical structure, specifically, for example, it can be selected The acrylic cylindrical tank structure, made of existing acrylic material, can be designed with a volume of 5-20L according to experimental requirements. The short tube extensions at both ends of the horizontal vortex reactor effectively prevent splashing of organic solid waste. The weighing system 9 (weighing device) includes, from top to bottom, an electronic scale tray 16, a shock-absorbing pad 17, an electronic scale support frame 18, and a weighing sensor 19. The rotating platform 8 is mounted on the weighing system via a shock-absorbing base 15. In this invention, the accuracy of the weighing system can be, for example, 1g, or a weighing sensor with higher accuracy can be selected. L-shaped guide rails 14 are provided on opposite sides of the rotating platform 8 along the radial direction of the horizontal vortex reactor 2. The L-shaped guide rails 14 are located below the rotating platform 8 and have a gap between them. These rails limit the horizontal displacement of the rotating platform 8 and allow it to float vertically (up and down). In this invention, the L-shaped guide rails specifically limit the displacement of the rotating platform on the horizontal plane, and more specifically, limit its front-to-back displacement on the horizontal plane to prevent it from shaking back and forth. In this invention, the vertical direction refers to the direction perpendicular to the horizontal plane.

The ventilation pipe 7 is equipped with a heating element, and a support rod 11 for supporting the ventilation pipe 7 is provided below the ventilation pipe 7; the number of support rods 11 can be, for example, 2 to 3; in this utility model, the duct fan 5 includes a frequency converter with ventilation rate adjustment; one end of the short pipe of the horizontal vortex reactor 2 is connected to the duct fan 5; the end of the ventilation pipe 7 away from the duct fan 5 is the ventilation inlet 12, and the other end of the short pipe of the horizontal vortex reactor 2 is the ventilation outlet 13.

[0025] In existing technologies, the dynamic tumbling of horizontal rotary fermenters during operation exacerbates the challenges of real-time weighing measurement. Rotation induces vibration errors, resulting in poor accuracy, reliability, and experimental repeatability of weighing data. The weighing system in this invention is key to achieving accurate real-time monitoring. It employs a conventional electronic scale (the core measuring device) and integrates three-stage vibration reduction measures (also known as anti-vibration measures) to achieve a precise real-time weighing system. This reduces vibration errors caused by rotation, ensures data reliability and experimental repeatability, effectively eliminates vibration interference generated during the rotation of the horizontal rotary reactor, and ensures that the device can continuously and stably collect material mass change data during operation, providing real-time data support for drying kinetic analysis. Specifically, the weighing system in this invention integrates the following three-stage vibration reduction: a vibration-damping pad (preferably with a thickness ≥10mm) is added to the bottom of the electronic scale tray to absorb most of the vertical vibration; a vibration-damping base is installed between the rotary table and the electronic scale tray to absorb the low-frequency vibration of the rotary table; and L-shaped guide rails are installed on both sides of the rotary table to limit the horizontal displacement of the rotary table while retaining vertical floating space.

In this utility model, the heating band can be, for example, a silicone heating band formed by covering the heating wire with silicone as the heat insulation outer layer, that is, the silicone heating band includes the heating wire and the silicone heat insulation outer layer covering the heating wire.

Specifically, the flexible connection scheme is as follows: the duct fan and the horizontal vortex reactor are connected by a silicone air duct (also referred to as a silicone hose).

Specifically, on the one hand, a tail gas condensation collection device can be externally connected and / or temperature and humidity sensors can be configured at the ventilation inlet and / or the ventilation outlet to achieve dual verification of moisture removal by quantifying the mass of condensate or calculating the difference in air humidity between the inlet and outlet, thereby calibrating the weighing system data; on the other hand, it is preferable that the outer periphery of the horizontal vortex reactor is covered with a heat insulation layer to reduce heat loss, reduce energy consumption, and ensure the temperature stability of the drying process.

An insulation layer is provided on the outer periphery of the horizontal vortex reactor.The horizontal rotary organic solid waste drying device includes a duct fan, a rotary table, a weighing sensor, a digital temperature controller, a tail gas condensation and collection device, and / or a temperature and humidity sensor connected to a data acquisition system.

[0042] To address the high cost of traditional customized experimental equipment (comparable equipment on the market generally costs over 4000 yuan per unit), this invention significantly reduces the cost of the device through material substitution, equipment reuse, and structural simplification. In the selection of core components, the horizontal rotary reactor uses highly transparent acrylic material instead of the traditional stainless steel tank, which not only reduces processing difficulty and material costs but also allows for direct observation of the material state inside the tank. The rotating platform uses a mechanism that drives the cylinder to rotate; stable rotation of the horizontal rotary reactor is achieved through the cooperation of a transmission belt and transmission gears, avoiding the high cost of customized rotating structures. The preheating and ventilation system abandons the complex independent preheater design, directly integrating a 200W heating jacket (equipped with a temperature probe and digital temperature controller) on the outer periphery of the ventilation duct. The weighing system reuses a standard 60kg range electronic scale (1g accuracy) used in laboratories, avoiding the development costs of customized sensors. The power module uses a low-cost duct fan instead of a dedicated variable frequency motor, meeting ventilation volume adjustment requirements while further reducing costs. Furthermore, the three-stage vibration reduction design and flexible connection design adopted in this invention effectively control additional costs. This utility model, through standardized procurement and modular assembly (each functional module is independently designed for easy disassembly and maintenance), can control the material cost of a single 5L small device to around 1,000 yuan, which is no more than 1 / 4 of the cost of traditional customized equipment, significantly improving the economic efficiency and versatility of the device.

[0043] The horizontal rotary organic solid waste drying device described in this utility model achieves laboratory simulation of an industrial-grade dynamic drying environment through modular design. Preferably, it mainly comprises four functional modules: a horizontal rotary reactor, a weighing system, a preheating and ventilation system, and auxiliary units. The workflow of the horizontal rotary organic solid waste drying device can be divided into four stages: material preparation, parameter setting, dynamic operation, and data acquisition. During the experiment, the organic solid waste material to be treated (such as sludge, cow dung particles, etc.) is first loaded into the horizontal rotary reactor, and key parameters such as rotation speed, ventilation volume, and preheating temperature are set according to the experimental plan. Then, preheating is started. The ventilation system preheats the air entering the horizontal vortex reactor using heating elements. Driven by a duct fan, the hot air penetrates the organic solid waste material layer, making full contact with the material and carrying away evaporated moisture. During this process, the weighing system records the material mass changes in real time. Combined with data from inlet and outlet temperature and humidity sensors, key indicators such as moisture removal rate and drying rate can be calculated simultaneously. After the experiment, the data acquisition system automatically outputs drying kinetic curves (such as mass change-time curves, moisture removal rate-temperature curves, etc.), providing experimental basis for analyzing the influencing factors of the drying process (such as rotation speed, temperature, ventilation volume, etc.) and optimizing process parameters.

[0044] This invention, through structural innovation and cost optimization, particularly the integration of mechanical shock absorption and flexible connection in some preferred embodiments, constructs a solid waste drying experimental device that integrates dynamic simulation, real-time monitoring, and multi-functional parameter control. It can not only reproduce the industrial dynamic drying process, but also has advantages such as low cost, easy operation, and more reliable data. It can be widely used in the study of solid waste treatment mechanisms and process development in agriculture, environmental engineering and other fields, providing a powerful tool for promoting the laboratory basic research and industrial application transformation of solid waste drying technology.

[0047] In a study on the resource utilization of cow manure in the chemical engineering laboratory of a certain industrial university, a simulation experiment on the optimization of low-temperature drying parameters based on the recovery of fermentation waste heat was carried out using the horizontal rotary organic solid waste drying device described in this embodiment. The experiment used granular cow manure with an initial moisture content (relative moisture content) of 55% (particle size controlled at 5-7 mm, total weight 520 g). During the experiment, the effects of inlet air temperature (48℃, 58℃, 69℃, 80℃) and ventilation rate (0.5 m / s, 1 m / s, 1.5 m / s, 2 m / s, 2.5 m / s, 3 m / s, 4 m / s) on drying efficiency were monitored simultaneously. The amount of moisture removed was verified by using temperature and humidity sensors (accuracy ±2%RH and ±0.2%℃) and a tail gas condensation collection device. The results are as follows: Figure 8 and Figure 9 As shown.

[0048] Figure 8 Experimental results show that under the conditions of an inlet air temperature of 58℃, a rotation speed of 1 rps (1 r / s), and a ventilation rate of 1.5 m / s, after the horizontal rotary organic solid waste device ran continuously for 45 minutes, the material moisture content decreased from 55% to 46.5%. The real-time weighing system recorded a moisture removal of 83 g, with a relative error of 2.2% compared to the condensate collection (81.2 g), verifying the reliability of the data. Comparison of different temperature groups revealed that when the inlet air temperature increased from 48℃ to 80℃, the drying rate increased from 8.35% / h to 18.4% / h (an increase of 120.4%). Process simulation using STARCCM+ software showed an average absolute percentage error of only 0.46% between the measured and simulated moisture content data. Comparison of different ventilation rate groups (see...) Figure 9It was found that when the intake temperature was 80℃, as the ventilation rate increased from 0.5m / s to 4m / s, the drying rate increased from 3.3% / h (corresponding to the result of ventilation rate 0.5m / s) to 19.7% / h (corresponding to the result of ventilation rate 2m / s) and then decreased to 9.0% / h (corresponding to the result of ventilation rate 4m / s), indicating that there is an optimal ventilation rate range.

A support rod is provided below the ventilation pipe to support the ventilation pipe and the heating sleeve, and the support rod is connected to the heating sleeve.

[0050] A research institute used the horizontal rotary organic solid waste drying device described in this embodiment to simulate the industrial horizontal rotary drying process of municipal sludge (pretreated with 60% moisture content and 2-4mm flocculent particles), focusing on the effects of ventilation rate and material residence time on drying kinetics. During the experiment, the preheating ventilation system was set with an inlet air temperature of 80℃, ventilation rates of 0.8 m / s and 1.6 m / s, and the horizontal rotary reactor rotation speed was fixed at 0.8 rpm. The initial sludge mass was 2.5 kg. After 3 hours of continuous operation, real-time monitoring data showed that when the ventilation rate increased from 0.8 m / s to 1.6 m / s, the time for the sludge moisture content to decrease from 60% to 45% was shortened from 115 minutes to 74 minutes, but the unit energy consumption increased by more than 40%, indicating the existence of an optimal energy efficiency balance point. Compared with the traditional static tray drying experiment (which takes 97 minutes under the same temperature and 1.6 m / s ventilation conditions), the dynamic horizontal rotary drying efficiency increased by 23.7%, verifying the device's high-fidelity simulation capability of industrial dynamic processes.

[0051] Comparative Example 1 A comparative experiment was conducted using a static tray drying oven (model DHG-9070A) commonly used in a university laboratory. 520g of the same batch of cow dung (initial moisture content 55%) was processed. The temperature was set at 58℃ and the air velocity at 1.5m / s (achieved via a fan on the top of the oven). A 20g sample was taken every 9 minutes to determine the moisture content. The results showed that the experiment required 5 interruptions, totaling 25 minutes of downtime. The final measured moisture content was 49.7%, which has an absolute error of 3.2% compared to the 46.5% obtained using the horizontal rotary organic solid waste drying device (dynamic device) of this invention. Furthermore, the localized sampling resulted in insufficient data representativeness (the moisture content difference between the upper and lower layers of material in the oven reached 5.2%). In addition, the static experiment could not simulate the particle size changes caused by material tumbling (such as particle breakage and agglomeration), while in industrial production, the particle size of sludge decreases from 5mm to about 2mm during the drying process, further affecting heat and mass transfer efficiency. This comparison shows that traditional static devices are difficult to meet the needs of dynamic drying mechanism research, while the device in this utility model effectively fills this gap through structural innovation.
