Controle de temperatura de um processo fotocatalítico com uso da plataforma arduino

Abstract

Control systems are essential to our society because with them it is possible to modify the state of a process using input parameters to deliver adequate output. There are several types of contollers and are mostly using sensors to detect the current state and the active ones to change the state according to the effects. This work was developed with the objective of controlling the performance of a non-institutional controller of a bioprocess laboratory at the Universidade Tecnológica Federal do Paraná, at the Francisco Beltrão campus. This is a process that performs the photocatonic actions by the action of ultraviolet light and catalyst, and the system is conducted in a closed system. The control system uses temperature and reactional volume level. Fans were installed without a reactor and with a flight control system with the use of Arduino microcontroller. As the temperature and the composition are reactive, the reaction rate parameters were performed for the process of recovering the interior temperature and for the installation of a temperature measuring system. Laboratory tests were compared to suit the controller parameters. In addition, the simulations were used to identify the best type of flux that stabilize the temperature inside the reactor. As a result, it was possible to observe that the internal temperature of the box where the reaction takes place remained at the target value, which in addition to allowing the evaluation of reactions under controlled temperature conditions.
