AI Technical Summary
Existing wet dust removal devices have poor dust reduction effects and cannot effectively handle the dust generated in drilling mud mixing systems, affecting workshop production safety and worker health.
Design a multi-stage wet dust collector, including a primary dust removal mechanism, a secondary dust removal mechanism, and a tertiary dust removal mechanism. It performs multi-stage dust reduction on the air through multi-stage spraying and filtration, and combines a water recycling system to improve the dust reduction effect.
Multi-stage dust reduction was achieved, significantly improving dust removal efficiency, reducing dust concentration in the workshop, lowering safety risks, and allowing the sludge to be recycled, thus improving economic benefits.
