Design And Application Of Performance Test System For Oil Absorbing Material

With the rapid growth of ocean oil production and transportation,global oil leakage accidents occur frequently.This not only causes waste of resources,but also pollutes the Marine environment,and even endangers human health.Therefore,oil spill treatment becomes a global hot issue.As one of the main methods of oil spill emergency treatment,adsorption materials have been paid more and more attention.There is no automatic test system for the performance test in the development of oil-absorbing materials.It is not possible to test the influence of environmental factors on adsorption performance.For quantitative analysis of oil absorption material performance,and observation of the continuous changes in the quality of absorption liquid in oil absorption material,a performance detection device for oil absorption material need to develop.Based on ASTM F726 adsorption material performance test standard,virtual instrument testing technology is applied to oil absorption material performance testing,and oil absorption material performance automatic testing system is designed.Test system including environmental factors monitoring system,reaction control system,automatic weighing system and solution preparation system.The environmental factor monitoring system mainly consists of temperature,pH,conductivity sensor and data acquisition card,which realizes real-time control of reaction tank temperature,pH and conductivity by using the upper computer.The reaction control system consists of reaction tank,heating tube,refrigerator,agitator pump,solenoid valve and liquid level sensor,which realizes the temperature control of the reaction tank and the mixture of reaction solution.The reaction control system consists of reaction tank,heating tube,refrigerator,agitator pump,solenoid valve and liquid level sensor,which realizes the temperature control of the reaction tank and the mixture of reaction solution.The automatic weighing system is composed of stepping motor,stepper motor controller and analytical balance,which realizes the control of stepping motor and automatic weighing of oil absorbing material.The solution preparation system is composed of the solution tank and peristaltic pump,which realizes the configuration and transmission of the solution In addition test system contains the function of the oil absorption material performance test data storage.Through modification of ramie oil absorption material performance test,this system have the functions to record the variation of absorption material quality with time and monitor the environmental factors change.So the Auto-testing system can improve the accuracy of the adsorption material performance testing.Using of automatic test system,the parameters of reactors can be controlled for the experimental temperature,electrical conductivity,pH respectively,when adsorption performance testing of the different oil absorption materials under different environmental is investigated.
