Description of the CFD engineering mission

EOLIOS designed the HVAC systems for a glove production plant.

How does a latex glove production plant work?

Udo usine from production from gants in latex is compoundee from moreieurs etapes. Tout dabord, the latex is mélangé à of additifs for créer the mélangel from base. This mélangel is ensuite heated and trained in a plastic material that can be stretched. The matiera plastics is ensuite placed in a mold and a neargo to hydraulics is utilisee for form the gant. Udo fois the gant formé, it peut être légerament refroidi, puis it is demorlé and lavé. Après the lavage, the gant peut être powder coating for the makesre more doux and for permandtre a meilleure prise in hand. Udo fois the gant séché, it is prêt à être emballé and expédié.

What is the impact of latex glove production on plant temperature?

The production from gants in latex a a impact direct on the température from lusine in raison from processus from chauffage and from refroidissement impliqué. Pendant the processus from chauffage, the mélangel from latex is chauffé à of températures élevées afin from the makesre malléable. The morthe and the neargo to hydraulics shave également chauffs afin from mieous form the gant. Pendant the processus from refroidissement, the gant is cooled à of températures more basses afin from the hardcir and from the make it more resistant. The heat released by the chauffage and the refroidissement peut to increase the temperature in the plant significantly.

For example, the areas where the latex mixture is heated and where the molds and hydraulic presses are heated are hotter than other areas of the plant. The areas where the glove is washed and dried are generally cooler than the other areas because they are not exposed to the same heating and cooling processes.

How do you properly size HVAC systems in this type of plant?

The challenge of such a project being the control of the particular thermo-aeraulic phenomena induced by the various high temperature manufacturing stages of a production (unspecified product). The CFD studies have made it possible to visualize the different thermo-aeraulic phenomena according to the seasons in order to optimize the climatic treatment systems.

The simulation CFD (Computational Fluid Dynamics) peut aider à solve heterogeneous temperature problems dyears a usine from production from gants in latex. The simulation CFD permet from simuler the flows and the morvements of fluides à lintérieon da usine and permet at ingénieurs from mieous compmakesre how différents facteurs peuwind affecter the température. The simulation CFD has thus allowed aider the ingénieurs à determine the best locations for the éthatipements, à optimiser the flows dair and à identify the sources from chaleon in.ubefore affecter the température.

Creation of the digital twin of a factory

Why and how?

The entire production line could be modeled in CFD. The furnaces, acid tank, equipment system and electrical power cabinet are precisely integrated into the study. The finesse of CFD resolution allows to obtain a complex temperature distribution but in the end very close to the actual conditions of use. The phenomena of induction of the blowing nozzles, as well as the effects of thermal plumes of the furnaces could be captured with great precision.

Understanding of thermo-aerodynamic phenomena

Understanding of the thermo-aerodynamic phenomena from the first phases of the study:

Thus, the first studies made it possible to understand the main thermal phenomena specific to the plant and its production system. The understanding of these phenomena and their simplified restitution to the design teams made it possible to concern all the teams in the design chain (HVAC engineer and Systems Engineer) in search of a solution. The use of the 3D model in the study phase has thus enabled the research and design of tailor-made heat capture systems directly designed to be integrated into production lines.

The 3D model specific to air diffusion was the subject of an iterative process that allowed the optimization of the diffusion successively. This was then completed taking into account the latest developments in the project in the context of HVAC design. In addition, the overall understanding of thermal phenomena has made it possible to refine the sizing of air exchangers for the creation of thermal recovery systems by the customer.

Understanding the diffusion of pollutants during production

At the same time, we are interested in hydrochloric acid soaking tanks for cleaning the products designed. This part of the production chain is characterized by the diffusion in the air of pollutants that need to be effectively captured. The evaluation of the concentration of particles was carried out not only near the emission zone, making it possible to check the proper functioning of the capture systems , but also throughout the plant, taking into account the particularity of the line. of production and the impact of each system.

How did the digital twin improve air quality?

The study of the diffusion of pollutants during the production phase consists in studying the different sources of pollution that can be generated by the production process. These include chemical use, energy-intensive equipment use, liquid and gas discharges, particulate emissions and noise emissions. A detailed analysis of the sources and consequences of the pollution can be carried out to determine the measures to be taken to reduce or control the pollutants produced. It is also possible to identify possible sources of contamination and take steps to avoid them. Finally, the analysis was able to highlight opportunities to improve environmental and worker health and safety performance.

Ainsi, the digital twin from the ligne from production a pu ovennir of informations précises and a analysis efficace of thermal flows in the environment. The rsultats obtenus have eté utiliss for optimiser the positionnement of éthatipements and the dimensionnement of HVAC systems, in order to achieve optimal operation within the limits imposed by safety standards.

In the end, our engineers have brought a global and thorough understanding of thermo-aerodynamic phenomena in design. System optimization and the development of safe measurement systems under study have made it possible to gain approximately 15°C in air temperature in the iso-flow chamber (= no additional installation cost). Tailor-made pollutant capture and energy recovery systems were able to be drawn and dimensioned.
