Aiming at the challenge of bad odors emanating from rotting perishable kitchen waste in summer within the garbage collection chain, the fan-pad system, which is widely used in agricultural facility systems, was applied to the design of community bins. In this regard, a community bin based on a fan-pad operating mechanism was developed. Computational fluid dynamics (CFD) was then used to numerically analyze the cooling effect of the community bin. Under conditions comprising of an outdoor temperature of 35 °C, an installation height of the wet curtain of the cooling system , an installation height of the fan , and varying distance d between the trash can and the wet curtain, and the average temperature of 16 temperature measurement points was analyzed. Design-Expert software was used to design the Box-Behnken Design (BBD) experiment, and regression analysis was carried out. Under the optimized parameter combination, the average temperature of the temperature measurement point was 24.82 °C by simulation. Through field test verification, it was established that the maximum relative error between the temperature of each measuring point and the simulation result was 1.54%, and the average temperature fluctuated within the range of 0.5 °C of the simulation value.: By creatively integrating the agricultural apparatus with our daily community bin, our research presents great interdisciplinary originality and potential in wide application. Meanwhile, our research also gives a new solution to saving the energy wasted by community dust room based on air conditioner cooling. We hold the believe that our research can arrest great attention of scholars, managers, and people interested in sanitation apparatus. Additionally, our research also provides more theoretical and technical support for the design and application of sanitation collecting apparatus.
针对夏季垃圾收集链中腐烂易腐厨余垃圾散发异味的问题,借鉴广泛应用于农业设施系统中的风扇-湿帘系统,将其应用于社区垃圾桶的设计中。为此,开发了一种基于风扇-湿帘运行机制的社区垃圾桶。然后使用计算流体动力学(CFD)对社区垃圾桶的冷却效果进行数值分析。在室外温度为 35°C、冷却系统湿帘安装高度、风扇安装高度以及垃圾桶与湿帘之间距离 d 变化、16 个温度测量点平均温度的条件下,分析了不同温度的变化。使用 Design-Expert 软件设计 Box-Behnken 设计(BBD)实验,并进行回归分析。在优化的参数组合下,通过模拟得到温度测量点的平均温度为 24.82°C。通过现场测试验证,建立了每个测量点的温度与模拟结果之间的最大相对误差为 1.54%,平均温度在模拟值 0.5°C 的范围内波动。通过将农业设备与我们的日常社区垃圾桶创造性地结合起来,我们的研究在广泛应用方面具有很大的跨学科创新性和潜力。同时,我们的研究也为基于空调冷却的社区灰尘室浪费能源的问题提供了新的解决方案。我们相信,我们的研究可以引起学者、管理人员和对卫生设备感兴趣的人们的关注。此外,我们的研究还为卫生收集设备的设计和应用提供了更多的理论和技术支持。
