Description
Изобретение относитс к процессам распы- ливани жидкости, например к процессам распыливани жидкого топлива.The invention relates to liquid spraying processes, for example liquid fuel spraying processes.
Цель изобретени - повышение степени дисцерсности распыла за счет реализации взрывного кипени жидкости в свободном объеме.The purpose of the invention is to increase the degree of atomization of the spray due to the realization of the explosive boiling of a liquid in free volume.
Способ распыливани жидкости включает нагрев жидкости в резервуаре и ее выдавливание через сопло в свободный объем.The method of spraying a fluid involves heating the fluid in the reservoir and squeezing it out through the nozzle into a free volume.
Температура Т нагрева жидкости выбрана равной 0,9-1,2 абсолютной критической температуры распыливаемой жидкости Tit, а давление Р выдавливани выбрано равным 1,0-3,0 критического давлени Р.The heating temperature T of the fluid is chosen equal to 0.9-1.2 of the absolute critical temperature of the sprayed liquid Tit, and the extrusion pressure P is chosen equal to 1.0-3.0 of the critical pressure P.
После выхода жидкости с температурой (0,90-1,2) Tfe в свободный объем происходит ее взрывное (гомогенное) кипение, в результате действи которого более половины жидкости прев,)а1цаетс в пар, а остальна часть диспергируетс на мелкие капли. При температуре жидкости ниже 0,90 Т ее взрывное кипение не происходит и жидкость диспергируетс обычным гетерогенным кипением, которое дает грубое распыление. Нагрев жидкости до температуры выше 1,2 Т не рационален, так как это приводит к резкому повышению давлени в резервуаре и химическому разложению жидкости.After a liquid with a temperature (0.90-1.2) Tfe emerges into the free volume, it explodes (homogeneous) boiling, as a result of which more than half of the liquid is transformed into vapor and the rest is dispersed into small droplets. When the temperature of the liquid is below 0.90 T, its explosive boiling does not occur and the liquid is dispersed by the usual heterogeneous boiling, which gives a coarse spray. Heating the liquid to a temperature above 1.2 T is not rational, as this leads to a sharp increase in pressure in the reservoir and chemical decomposition of the liquid.
Давление Р (1-3)Р/г, которым выдавливают жидкость через сопло, выше давлени пресыщенного пара жидкости, поэтому оно исключает запирание сопла кипением. При Р РА давление в канале сопла становитс равным давлению насыщени и канал запираетс .The pressure P (1-3) P / g, which squeezes the liquid through the nozzle, is higher than the pressure of the saturated steam liquid, so it eliminates the locking of the nozzle by boiling. With P PA, the pressure in the nozzle channel becomes equal to the saturation pressure and the channel is closed.
Использование давлений Р ЭР нецелесообразно , так как это не дает увеличени степени дисперсности распылени жидкости и сопр жено с дополнительными техническими трудност ми.The use of pressure P ER is impractical because it does not increase the degree of dispersion of the sprayed liquid and is associated with additional technical difficulties.
Пример 1. Керосин (Tjc 720 К, Pfj 4,1 МПа) нагревают до 650 К и выдавливают через сопло давлением 10 МПа.Example 1. Kerosene (Tjc 720 K, Pfj 4.1 MPa) is heated to 650 K and squeezed through a nozzle with a pressure of 10 MPa.
Пример 2. Аммиак (Т 405 К Р.к 11,2 МПа) нагревают до 420 К и выдавливают давлением 25 МПа.Example 2. Ammonia (T 405 K R.k 11.2 MPa) is heated to 420 K and squeezed by a pressure of 25 MPa.
Распыливание жидкости предлагаемым способом даст возможность повысить степеньSpraying the liquid with the proposed method will make it possible to increase the degree
ее распылени по крайней мере в 100 раз по сравнению с распылением обычными форсунками . Это обеспечит более полное сгорание топлива и тем самым даст значительную экономию топлива и уменьшит загр знение окружающей среды вредными продуктами сгорани . Предлагаемое изобретение не требует значительных капиталовложений и изменени технологии производства.it is sprayed at least 100 times compared to conventional nozzles. This will ensure a more complete combustion of the fuel and thus will lead to significant fuel savings and reduce environmental pollution by harmful combustion products. The present invention does not require significant capital investment and changes in production technology.
