Application And Research Of Solar Hybrid Energy In Straw Steam Explosion

The processing of agricultural of agricultural products is an important link in the agricultural process.It was provided energy mainly rely on coal,electricity,gas,the costs of production is not only high but also caused environment pollution.At the same time,utilization of crop straw is a difficult problem to the people,but the straw by steam explosion can be used as the cow forage,however the energy required cost restricted the use of straw.And the steam which is generated by solar energy,can provide energy for straw steam explosion,it could solve the energy problem and reduce the costs in the agricultural process.Solar energy is discontinuous energy which is affected by weather and time,Biomass fuels boiler that uses cow dung which has been specially processed instead of coal could make up for the lack of solar energy and ensure steam supplying stably reduce the costs.A solar-biomass fuels boiler was designed in view of the large livestock farms,it could provide steam for straw steam explosion and process cow forage,to achieve the goal of reducing costs,energy saving and emission reduction.1.In order to improve the solar steam generator heat collecting efficiency,designed the observe and control system,control strategy of solar generator based on PLC.2.According to the characteristics of solar-biomass fuels boiler,developed a simultaneous approach to solar energy steam generating device and boiler,and achieve the goal of the requirements of the hybrid system.According to the real-time parameters collected by PLC,coordinate the control system of solar-biomass fuels boiler,to achieve the goal of the maximum use of solar.3.The hardware and software of solar-biomass fuels boiler control system was constructed and developed the stem-heat pot.The steam-heat pot is provided energy by solar-biomass fuels boiler,realized thermal control of the fermentation device.4.The experimental design of solar-biomass fuels boiler.The test results turned out that the design of solar-biomass fuels boiler achieved the goal.Compared with coal-fired boilers,it can save 165 kg coal when generated a ton of steam.
