Reduction of environmental chemicals, toxicity and particulate matter in wet scrubber device to achieve zero emissions

Abstract

The fine particles generated by the foundry industry are present in the atmosphere; they have an impact on the climate because of their influence on atmospheric radioactive phenomena. As a result of this scenario, there is a rising amount of legislation restricting the emission of pollutants from foundry industries and related businesses. In response to this situation, many researchers have concentrated on end-of-pipe technologies, one of which is the wet scrubber, which is a device that is primarily used in foundries to control pollution and is one of the devices that has been incorporated. The disadvantage of using this wet scrubber, on the other hand, is that it contributes to secondary pollution when it is used. In order to combat secondary pollution, a model of an enhanced wet scrubber system that incorporates a multi-sand filtering technology was developed. The performance of this redesigned wet scrubber system was evaluated with the use of computational fluid dynamics (CFD) software. In CFD, the Reynolds stress model was applied for simulation. The pressure magnitudes and velocity magnitudes are obtained by this simulation. The volume fraction of the dust was evaluated through the DPM approach. Because of the introduction of the filtration tank's computation, it was discovered that successful filtration was accomplished using sand filters, meaning that environmental chemicals and particles were totally filtered from 0.17 kg at the entrance to zero kg of particles at the outflow.

Investigation of Mechanical and Thermal Stabilities of Tamarind Seed- and Peanut Shell Powder-Reinforced Vinyl Ester Composite

“…Studies conducted by Jagadeesh et al examined the usage of corn husk four, an agricultural byproduct, as reinforcement for thermoplastic polymers (polylactic acid). Tey proved this by adding the biofller fexural modulus enhanced with increasing fller loading (10,20,30, and 40 wt.%) and mesh size (50∼100, 100, and 300). Tey concluded that using materials derived from agrowaste as reinforcement in the manufacture of ecologically friendly composites is an attractive trend from the perspective of mechanical properties [19].…”

“…Tis simultaneous enhancement in both fexural strength and modulus underscores the efcacy of the TMS/PNS hybrid fller in reinforcing the composite for structural applications. Tis is because the hybrid fller has a larger elasticity modulus than pure resin [29][30][31][32][33][34]. Te fexural resistance of the material improves when there is excellent adhesion between the fller and the resin at the interface.…”

Analysis of the dedusting process in a rectangular chamber filter

“…Technological processes, as well as numerous anthropogenic activities, are very often associated with the emission of the dust generated during their lifespan 1, 2 . It is an important and difficult topic, because the generated pollutants pose a direct threat to both the broadly understood environment and the people living in its surroundings 3,4 . There are standards that defi ne the limit values for dust concentrations in air, which are set by bodies such as the European Parliament and the Council of the European Union.…”
