摘要
实验室好氧堆肥反应系统具有规模小、容易操作的特点,然而由于其规模小导致在实验室很难成功进行堆肥过程模拟。小型好氧堆肥反应系统易受外界条件影响,如自发产热少、热损失大,从而造成温度无法升高或无法达到堆肥所需最适温度(50~60℃)。温度是堆肥过程中最直接和可靠的操作参数。本文堆肥系统对堆肥过程温度、通风量和尾气CO_(2)自动监测,通过设置程序控制,尤其在温度无法满足堆肥过程要求时进行自动补热和通风控制,让堆肥过程顺利进行,避免实验失败。
The laboratory aerobic composting system has the characteristics of small scale and easy to operation.However,due to its small scale,it is difficult to successfully simulate the composting process in the laboratory.The small-scale aerobic composting system is susceptible to external conditions,such as low spontaneous heat production and large heat loss,causing the temperature to be unable to rise or to fail to reach the optimum temperature(50~60℃)required for composting.Temperature is the most direct and reliable operating parameter in composting process.The composting system automatically monitors the composting temperature,ventilation,and CO_(2) emission,and is controlled by setting programs,especially when the temperature cannot meet the requirements of the composting process,it starts automatic heat supplementation and ventilation control,so that the composting process can proceed smoothly and avoid experimental failures.
