Embodiment

[0032] When the nozzle of the present invention is working, the low-pressure desuperheating medium is rotated and atomized for the first time through the rotating inclined hole 5, and then directly reaches the inner cavity of the nozzle 4 through the conical narrowing cavity flow channel inside the conical valve core 7, and the conical constricting cavity The cavity flow channel can maximize the flow rate at the outlet, which is helpful for the atomization of the low-pressure desuperheating medium.

[0033] Due to the small pressure difference between the low-pressure desuperheating medium and the superheated steam in the above design, it is not enough to rely on the pressure difference to achieve a satisfactory atomization effect, so it is necessary to introduce another high-temperature and high-pressure medium to assist. The high-temperature and high-pressure medium enters the high-pressure flow inside the shell 1 through the threaded joint 2 The channel 3 then enters the ann...

Abstract

The invention discloses a high-low-pressure mixed atomization nozzle, belongs to the industry field, and relates to an atomization nozzle, accordingly, high-pressure and high-temperature media serve as auxiliary atomization media, low-temperature and low-pressure media are improved in advance and converted into media good in atomization effect, then, the media are mixed with third media, and the purpose of uniform medium mixing is achieved. A shell, a conical valve element, a nozzle sleeve and a nozzle are included. The nozzle is in threaded connection with the front end of the shell, and therear portion of the nozzle is sleeved with the nozzle sleeve. The front end of the conical valve element penetrates through the nozzle sleeve and enters the nozzle, and the rear portion of the conicalvalve element is connected with an inclined hole ring. The ring edge of the inclined hole ring is provided with evenly-distributed rotation inclined holes obliquely penetrating through the ring edge.The two sides of the nozzle sleeve in the shell are connected with an annular runner arranged in the shell. One side of the annular runner is connected with the end portion of a high-pressure runner.A threaded connector is arranged on the outer side of the shell, one end of the threaded connector communicates with the tail of the high-pressure runner, and the other end of the threaded connectoris connected with peripheral equipment. An outer circular ring of the nozzle sleeve is provided with a circle of flow groove, and the protruding step part is an arc chamfered runner.

Description

technical field [0001] The invention relates to a high-low pressure mixed atomizing nozzle belonging to the industrial field, and relates to a method of using high-pressure and high-temperature medium as an auxiliary atomizing medium to improve the low-temperature and low-pressure medium in advance and transform it into a medium with good atomization effect, and then mix it with a third medium. The atomizing nozzle for the purpose of achieving uniform mixed media is especially suitable for the desuperheating of superheated steam in the power steam pipe network, especially when the pressure difference of the low-temperature medium is low. Background technique [0002] In superheated steam occasions such as boilers and power stations, multi-stage desuperheating of superheated steam is often required to meet the temperature requirements of different equipment for superheated steam through steam turbines to downstream devices. The desuperheating medium is mostly desalted water, c...
