| 摘要 |
The present invention relates to an evaporation cooling type spraying device of an ultrafine atomization liquid drop forming nozzle assembly and, more specifically, to an evaporation cooling type spraying device of an ultrafine atomization liquid drop forming nozzle assembly, capable of cooling and purifying surrounding air by spraying liquid drops of an ultrafine atomization liquid drop form from the nozzle assembly maintained in high pressure. The evaporation cooling type spraying device includes: a liquid supply source (S) of supplying a liquid for generating the liquid drops; a pressing unit (11) of transferring the liquid supplied to the liquid supply source (S); a nozzle block including at least one nozzle assembly (13a,13b,13c,13d) of generating the ultrafine atomization liquid drop with a predetermined diameter from the liquid supplied by passing through the pressing unit (11); and a control unit (16) controlling the pressure of the pressing unit (11). The pressure of the nozzle assembly (13a,13b,13c,13d) is maintained in the pressure of 40-80 bar by the pressing unit (11), and the predetermined diameter is 5-40 um. |
