Design of Intelligent Release System of CO in Solar Greenhouse

将温室CO2浓度控制在一定范围内可以增强光合效率,进而提高作物产量和品质。本文通过控制液态反应物来控制反应速度设计出CO2浓度智能释放系统。参照医学药液注射器的工作原理,设计出气密性良好的液体控制器,即通过输液管道输入中间的产气反应装置;中间的产气装置添加固体的碳酸盐,与流入液态稀硫酸或稀盐酸发生反应,产生CO2气体,反应装置的另一侧设计有洗气装置,将产生的CO2气体除去杂质,然后经输气管道施向温室,形成CO2智能释放系统。

Controlling CO2 concentration in greenhouse can enhance photosynthetic efficiency and improve cropyield and quality.Refer to the equipment that is used to create chemical reaction between liquid and solid,an intelli-gent release system of CO2 concentration was designed by controlling the reaction speed that is connected with liq-uid reactants.According to the working principle of medical liquid syringe,a liquid controller with good air gas tight-ness was designed.And liquid was input to the gas-producing reaction device which located in the middle of the in-fusion pipe.In the middle of the gas production device,solid carbonate was added,which reacts with dilute sulfuricacid or dilute hydrochloric acid flowing into the liquid to produce CO2 gas.On the other side of the reactor is a gaswashing device,which removes impurities from the CO2 gas and then sends it to the greenhouse through a gas pipe-line.Combined with the use of greenhouse CO2 concentration detection instrument,a set of CO2 intelligent releasesystem is formed by intelligent control.
