(54) ФОРСУНКА ВНУТРЕННЕГО СМЕШЕНИЯ(54) INSIDE INTERMEDIATE MIX

II

Изобретение относитс к устройствам дл распыливйни топлива и может быть использовано в теплоэнергетических установках. .The invention relates to devices for spraying fuel and can be used in heat and power plants. .

По основному авт. св. № 805006 известна форсунка, содержаща корпус с соплом, образующий камеру закручивани , снабженную наклонными входными каналами, размещенными по ее длине трем кольцевыми р дами, причем каналы первого и второго со стороны сопла р да подключены к источнику окислител и наклонены в противоположные стороны, а каналы третьего р да сообщены с источником топлива и наклонены в ту же сторону, что и каналы первого р да, причем все каналы расположены тангенциально относительно образующей камеры закручивани .According to the main author. St. No. 805006 a nozzle is known, comprising a housing with a nozzle, forming a twisting chamber, provided with inclined inlet channels arranged along its length in three annular rows, the first and second channels from the side of the nozzle being connected to the oxidizer source and tilted in opposite directions, and the channels the third row is connected to the fuel source and tilted in the same direction as the channels of the first row, with all the channels located tangentially relative to the generator of the twisting chamber.

Недостаток известной конструкции заключаетс в низком качестве смешени .A disadvantage of the known construction is the low quality of mixing.

Цель изобретени - повышение качества смешени .The purpose of the invention is to improve the quality of mixing.

Указанна цель достигаетс тем, что во втором и третьем р дах выполнены дополнительные тангенциальные каналы, а коаксиально корпусу, с его внешней стороны, последовательно установлены коллектор окислител и топливный коллектор, причем входные каналы первого, второго и дополнительto ные каналы третьего р дов подключены к коллектору окислител , а дополнительные каналы второго и входные каналы .третьего р дов - к топливному коллектору.This goal is achieved by the fact that in the second and third rows additional tangential channels are made, and coaxially to the case, on its outer side, an oxidizer collector and a fuel collector are sequentially installed, the input channels of the first, second and additional channels of the third row being connected to the collector oxidizer, and additional channels of the second and input channels of the third row - to the fuel manifold.

tsts

Кроме того, входные и дополнительные каналы второго и третьего р дов расположены соосно один в другом.In addition, the input and additional channels of the second and third rows are located coaxially in one another.

Во входных и дополнительных каналах второго и третьего р дов устаX новлены завихрители.In the input and additional channels of the second and third series of devices, twisters are updated.

Claims

FIG. 1 shows the nozzle, a cross-section; in fig. 2 is a section A-A in FIG. one; in fig. 3 section bb in fig, 1; FIG. - section BB in FIG. one; in fig. 5 and 6, respectively, of the sections A-A and BB in FIG. 1 with coaxial arrangement of the input and additional channels in FIG. 7, node I in FIG. 5. The internal mixing nozzle comprises a housing 1 with a nozzle 2, forming a twisting chamber 3, provided with inclined inlet channels 5 and 6 located along the length of the chamber 3 for twisting. Channels 5 and 5 of the first and second from the side of the nozzle are connected in a row to the source of oxidizer and tilted in opposite directions, and channels 6 of the third row are connected to the fuel source. The channels k of the first p la and channels 6 of the third row are inclined in the same direction. All channels 5 and 6 are located tangentially with respect to the generator of the spinning chamber .3. In the second and third rows, additional tangential channels 7 and 8 are made. The coaxial of the housing 1 on its outer side has a consistently installed manifold 9 of oxidizer and a fuel manifold 10. The input channels k and S of the first, the second and additional channels 8 of the third row are connected to the collector 9 is an oxide of a fuel, and the additional channels 7 of the second and input channels 6 of the third row are connected to the fuel collector 10. The input and additional channels 5 and 6, 7 and 8 of the second and third rows are located coaxially in one another (Fig. 5 and 6 ). In the input and additional channels 5 and 6, 7 - and 8 of the second and third rows are installed swirlers 11 and 12. The nozzle works as follows. The oxidizer from the collector 9 oxidizes the bodies through the inlet and additional channels 5 and 8 into the chamber 3 for spinning, where it interacts with the fuel coming from the fuel collector 10 through the inlet and additional channels 6 and 7. The mixture formed with the fuel enters the oxidizer from the oxidizer collector 9 through the input channels t, as a result of which a gradual supply of the oxidizing agent is provided. When executing the nozzle with the input and additional channels 5 and 6, 7 and 8 located coaxially and also when installed in this x channels 5, 6, 7 and 8 swirlers 11 and 12 formed, for example as a screw, is intensified mixing process of fuel and oxidizer. Claims of the invention 1. Internal mixing vortex by aut. St. No. 805006, characterized in that, in order to improve the quality of mixing, additional tangential channels are made in the second and third rows, and an oxidizer collector and a fuel collector are sequentially installed coaxially to the body, on its outer side, the input channels of the first, second and Additional channels of the third row are connected to the oxidizer collector, and additional channels of the second and input channels of the third row are connected to the fuel manifold.

2. The injector according to claim 1, in connection with the fact that the input and additional channels of the second and third rows are located coaxially in one another.

3. The nozzle on the PP. 1 and 2, which means that swirlers are installed in the input and additional channels of the second and third rows.
