Exhaust gas collection system using vortex tube {EXHAUST GAS COLLECTION SYSTEM USING VORTEX TUBE}

The present invention relates to an exhaust gas collection device using a vortex tube, wherein the exhaust gas discharged from the engine is separated from high temperature air and low temperature air through a vortex tube device, and CO2 or H2O is separated and discharged at a selected air temperature among them. It relates to an exhaust gas collection device using a vortex tube capable of improving the performance of the device and reducing exhaust gas.

In general, vehicle engines generate power by mixing fuel and air and burning them in a cylinder chamber, and at this time, the burned exhaust gas is discharged to the outside through an exhaust system.

The exhaust gas uses an exhaust gas recirculation system (EGR) to remove harmful substances such as nitrogen oxides and carbon monoxide.

However, the engine using the exhaust gas recirculation system consumes engine coolant for cooling the recirculation system, increases the weight of the vehicle and takes up a lot of installation space in the vehicle as components such as piping and EGR cooler are required. There is a problem of reducing the driving performance of the vehicle due to the increase in air resistance.

In order to solve this problem, an engine system equipped with a vortex tube for replacing the intercooler and the RG cooler has been previously applied as a prior art of the present inventor.

This prior art needs to minimize pressure loss or heat loss while the recycled exhaust gas flowing into the vortex tube is introduced into the vortex tube, and when the pressure loss or heat loss of the recycle gas flowing into the vortex tube is large, the vortex tube There is a problem that not only the energy separation or material separation efficiency of the recycle gas is reduced, but also the filtering efficiency of the soot material is extremely reduced.

In addition, when the exhaust gas recirculation engine system using the vortex tube device fails to actively control the supply amount by which the low temperature gas separated by the vortex tube is recirculated to the intake manifold side of the engine, that is, the exhaust gas recirculation rate (EGR rate) It can reduce the combustion efficiency or output performance of the engine.
