Study And Design Of Green Plant Purification Laboratory For Automobile Exhausts

The environment protection is the topic that industry and agriculture in the world develops nowadays. In recent years, the automobile exhaust's pollution becomes the main source in the atmospheric contamination, along with the increasing of the quantity of vehicles. It is true that automobile exhaust's pollution to the atmospheric environment has become more and more serious. At present, most of researches point at improving of purificatory measure of automobile itself, but the improving space isn't very large relatively. In views of the abovementioned facts, this paper sets a new task what is aimed at automobile-outside purificatory study. To study and devise an airtight laboratory that is direct against to automobile exhaust's pollutions. This laboratory is mainly for the sake of the research on trees' purificatory to automobile pollutions. According to GB3095-1996《The quality standard of atmospheric enviroment》and GB 18285-2000《The nomenclature and definition of Automobile Exhaust's Pollution》, we compounds the quota of automobile exhaust's contamination, use the the trees to absorb it, and obtain the rule that the trees adsorbes automobile exhaustion.In the process of laboratory design, we make the design standard of purificatory laboratory, such as the temperature, pressure and airtight property. And according to the characterist of the plant light-synthesis, the intensity of illumination is also required, when the sunlight isn't enough, we need to adopt simulant lamp-source to compensate the sunlight.Based on analysing and comparing the domestic and foreign correlative environment laboratory, this article has used the advanced computer measure and control technology, the article use Delphi to develop the monitoring software under WindowsXP environment, to utilize PLC to control the entire experimental system. The Developed system has achieved the level of automatic control. The developed system has friendly interface and flexible operaty, it not only can ensure the accuracy and reliability of experimentation, but also can complete the work more efficiently than the manual work before.The paper introduced the design idea for the plant purificatory laboratory for automobile exhaust in detail, equipment selection and the entire design process of system, given an instance of purifing CO, according to the trees of Euonymus japonlcus which we always plant in road, and then make the appraisal of the entire experimental, the test is based on the reasonable testing plan, the experimental technique and the method, The experiment proved that the designs of plant purificatory laboratory for Automobile Exhausts has been reached the design goal. This research of plant purificatory laboratory for Automobile Exhausts may direct the urban road afforestation plan design, simultaneously it will be able to provide a good experimental foundation and tests platform for the automobile exhaust purification research.
