Tests on High-pressure Water Rotational Jetting Ventilation Cooling Characteristic

摘要

In order to improve the cooling effect and practical applicability of falling temperature technique on high-temperature workplaces, the aeration and cooling principle of the high pressure water rotational jetting ventilation were analysed, and the experimental study was carried out. The results show that water pressure and cooling rate are an approximation of parabolic growth relationship, different structure of jet tube and temperature difference on water and gas also have an obvious effect on the cooling amplitude and air quantity. The guide vanes installed may improve effect of ventilation and cooling the capacity on high pressure water rotational jetting.
