Method of isothermic compression of air and nozzle arrangement for carrying out the process

摘要

An atomizer unit (2) forms a water/air mixture (4), which is fed into a jet unit at a speed higher than the speed of sound. During atomization, fluid droplets with a diameter of approx. 200 mu or smaller are formed in the mixture. Before passing through the atomizer unit, the fluid temperature is slightly above the evaporation temperature of the pressure-charged fluid, and the fluid is mixed with a second fluid at a pressure and temperature, so that the triple point of the second fluid is not exceeded. After the mixture has passed through the atomizer unit, the triple point of the second fluid is exceeded due to pressure drop, thereby causing it to be evaporated. The second fluid is liquid CO2, esp. exhaust gas from an IC engine.
