Creation of a new energy-efficient design of the dustexhaust system

Abstract

Aspiration systems of processing enterprises (local exhaust ventilation) consume a lot of electricity. The article discusses the new energy-efficient design of the aspiration system when using inclined overload gutters. Energy efficiency is the use of the principle of partial recirculation of aspirated air and the Coanda effect when it is fed directly into the transshipment chute. The article discusses in detail the new effective unit for supplying recirculated air to the reloading chute. The use of the proposed design will reduce more than twice the energy consumption of aspiration systems and the energy intensity of general ventilation systems that supply air to the room. The article provides theoretical information on the operation of systems, the results of the experiment.

The Applicability of Coanda Effect Hysteresis for Designing Unsteady Ventilation Systems

“…The Coanda effect was also used to design a dust exhaust system where the volume of exhaust air was decreased by more than 50%. The proposed solution can be applied to decrease energy consumption in dust exhaust and general ventilation systems by as much as 30-70% [99].…”
