【摘要】 生物柴油是一种值得大力生产和推广的新型能源,本文介绍了酯交换反应制备生物柴油的工艺原理及控制系统的组成。针对此装置中存在的自控水平低及生物柴油产率低的问题,本控制系统利用串行通信和连锁实现了原料自动供给,提高了自控水平;利用连续PID占空比控制方式,改善了对反应釜液位的控制品质,极大地提高了生物柴油的产率。更多还原

【Abstract】 Bio-diesel is a new energy which deserves vigorously promoted and produced,this paper introduced the principle of bio- diesel production, and the control components of the system. Directing at the low control level and the low yield of bio-diesel in the current device,we enhanced the Automatic level of control system by the use of serial communication and chain control;And the improvement of the control level of the quality the reactor by taking advantage of the continues PID controller in mode of duty cycle which greatly increased yield of bio-diesel.更多还原
