Diseño de una planta piloto para la caracterización de sólidos


Camba Rodríguez, Raquel

Due to the great variety and complexity of powdered products, there is a lack of mathematical models that adequately adjust the two-phase systems that make up the pneumatic transport methods. This often makes it necessary to carry out experimental tests to determine the behavior of the product. In this work a pilot plant has been designed, it will be possible to find both the analysis of the process diagram, going through the justification of the 3D model and the detail and even the construction of the installation itself. It is a highly versatile pilot plant that allows testing the three types of pneumatic transport (dense phase, dense pulsed phase and dilute phase), in addition to being able to carry out the two existing pneumatic transport systems, by suction and impulsion. With the help of a rheometer, a statistical analysis has been carried out on the differences between the parameters of the products depending on the type of solid, whether it is a product in powder, granules or a pellet. This product characterization analysis has allowed the development of a graph that helps decision-making on what type of pneumatic transport flow is most suitable for each product. Also, the testing methodology to be followed in the pneumatic installation is described in order to find the appropriate transport for each product. Once this optimal transport has been found, the experimental tests are carried out to obtain the values ​​of the measurements of the air speed, the mass flow of the product and the head loss of the overall line. Once these data are obtained, a scaling methodology is proposed for the sizing of turbo blower pumps in industrial plants, which has provided reasonable results.
