Small and Medium-sized Ship Exhaust Heat Recovery Device Based on Vortex Tube Effect Verification

Abstract

With the continuous development of China's economy, the number of Chinese ships has increased year by year. The problem of low utilization rate of waste heat energy of diesel exhaust in existing small and medium-sized ships has become increasingly prominent, and the distillation method in marine desalination has high energy consumption and large equipment volume. Reverse osmosis is a serious pollution. Based on this, we designed a small and medium-sized ship exhaust heat and lightening device based on vortex tube effect. Compared with the traditional lightening technology, the design advantages of this work are reflected in the following three aspects: 1) designing the vortex tube cold and heat separation effect, achieving the step utilization of the exhaust air, reducing the power consumption; 2) the device is small in size and can save The internal space of the ship; 3) The desalination process is simple, there is no influent pretreatment process, and the environmental pollution of the chemical agent is reduced; 4) The device can provide a negative pressure environment for the exhaust port of the diesel engine, reduce the exhaust back pressure of the diesel engine, and improve the working efficiency of the diesel engine.
