The exhaust gas temperature changes with the amount of water sprayed. When the amount of water spray is less than a certain value, the water vapor obtained by evaporation of water droplets cannot saturate the humid air. If it is not satisfied, the calculation result cannot be obtained; as the amount of water spray increases, the heat absorption of the water droplet increases (including gas). The latent heat and the sensible heat absorbed by the temperature rise of the water droplets), so that the exhaust gas temperature is lowered. When the amount of water spray is small, the difference in exhaust temperature corresponding to different spray temperatures is small. This is because the heat transfer is mainly latent heat, and the sensible heat transfer caused by the different spray temperatures is only a small part. As the amount of water spray increases, the temperature of the exhaust gas tends to decrease slowly. This is because the spray temperature is higher than the intake temperature. As the amount of water spray increases, the proportion of sensible heat increases. The difference in thermal temperature is continuously reduced. Increasing the amount of water spray to reduce the temperature of the exhaust gas is not as obvious as when the amount of water spray is small. This slowing tendency is more obvious when the water spray temperature is higher.

In this paper, a new model for calculating the evaporation of droplets in the process of water-cooling evaporation is proposed. Based on this, a mathematical model of the compression process of the water-jet vortex air compressor is established. According to the model, the calculated results are more accurate. The model is used for compressor design and model calculation; the model is based on the fact that the humid air is always saturated during the compression process, so the water spray quantity needs to be greater than a certain value. When the value is less than this value, the algorithm does not converge and the calculation result cannot be obtained; Exhaust gas temperature can be reduced by spraying water temperature or increasing water spray volume; in actual compressors, power consumption increases due to leakage effects, so under the same conditions, the actual exhaust gas temperature is higher than the calculation in this paper. result.
