た。However, in the case of spraying various reactants and agricultural chemicals in a flat plate shape, there is a limit to the uniform spraying by the cylindrical nozzle using the above-mentioned cylindrical dispersion cylinder, and particularly the reaction However, there is a problem in that sufficient uniformity cannot be obtained by rotating the cylindrical nozzle in the form of a pendulum when it is desired to proceed uniformly in time. Further, when a flat plate nozzle composed of a flat plate-shaped dispersion cylinder is used, the flow path is expanded from the conduit to the dispersion cylinder, and the fluid such as the reactant is discharged while expanding the flow path in a flat plate shape. In order to uniformly expand the flow path, it is necessary to provide baffles and guide plates in the dispersion cylinder. However, in this case, it is difficult to properly dispose the baffle plate, and there is a problem that not only an excessive pressure loss occurs depending on the disposition, but also a small change in the air volume impairs the uniformity of the spraying. In addition, this is not preferable from the viewpoint of energy saving and has a problem.

The fluid flowing therethrough is guided to the second pair of partition walls, and the inner partition walls of the second pair of partition walls further divide the flow path, whereby the flow path naturally and uniformly spreads. According to the spray nozzle of claim 3, since the opening area of the opening connected to the conduit of the dispersion cylinder and the opening area of the discharge side opening are formed to be substantially the same, the compressed gas and the fluid are formed. The flow velocities at the time of introduction and at the time of derivation of the

れる。Since the rear end of the second partition wall 13b is near the extension line of the partition body 121a of the first partition wall 12a, the discharge material flowing on the side plate 8a side is particularly discharged in the vicinity of the first partition wall 12a. Is discharged between the second partition walls 13a and 13b, and the discharged matter flowing near the side plate 8a flows between the side plate 8a and the second partition wall 13a. Similarly, the discharged matter flowing on the side plate 8b side, especially the discharged matter flowing near the first partition wall 12b, is between the second partition walls 13a and 13b, and the side plate 8b.
The discharged substances flowing in the vicinity flow between the side plate 8b and the second partition wall 13b. Then, the discharged substances respectively flowing further flow and are discharged from the discharge side opening 9. In addition, since the straight walls 122a and 122b are provided in the discharged products flowing between the first partition walls 12a and 12b, the discharged products flowing near the partition wall bodies 121a and 121b are further side plates 8a or side plates 8b. It is suppressed that the width of the flow path is widened in the direction, and as a result, most of the inner partition walls 1 in the second partition wall pair 11a, 11b are largely prevented.

This may be directly connected to the conduit 2, and in that case, the case where the connecting cylinder 4 intervenes the opening on the conduit 2 side and the rear end of the first partition wall pair 10 (the end on the conduit 2 side). Keep the same distance,
It is preferable that the discharge product flowing in from the conduit 2 is guided to the first pair of partition walls 10 after widening the width of the flow passage in the horizontal direction and narrowing the width of the flow passage in the vertical direction to some extent. This is because when the first partition wall pair 10 is near the opening of the conduit 2, the influence of the rear end faces of the first partition walls 12a and 12b cannot be ignored, and pressure loss occurs due to these rear end faces.
This is also because the flow is disturbed.

It is preferable because the pressure loss accompanying the change becomes small. Further, in the above-described embodiment, the angle (internal angle) formed by the partition walls in each partition wall pair is slightly larger than the angle (internal angle) formed by the side plates 8a and 8b, but they may be the same or slightly smaller. . Furthermore, although each partition wall is composed of a partition wall body and a straight wall, it is also possible to use only the partition wall body.

における散布を均一にすることができる。As described above, the spray nozzle according to claim 1 of the present invention as a whole eliminates a sudden change in the cross-sectional area from the conduit side to the discharge side, and is accompanied by a change in the cross-sectional area. The pressure loss is small, and in addition, each partition in the first pair of partitions is arranged almost parallel to the side plate, and the fluid flow path is enlarged without disturbing the flow of the fluid traveling along the side plate. As a result, a large pressure loss is not generated, and the partition walls are arranged apart from each other, and the pressure loss due to the partition walls is also reduced. Therefore, the ratio of the compressed gas to the fluid can be reduced, and the wind force can be reduced. It is possible to prevent the adverse effects of the above from affecting the reaction system, save energy, and reduce the flow rate of the compressed gas, so a compressed gas source such as a compressor can be used. It can be made compact whole in the mold. Also, since both side plates and both bulkheads are arranged symmetrically with respect to the central axis of the conduit, the flow between both side plates will be symmetrical with respect to the center line, thus ensuring uniform distribution between both side plates. You can

The advancing fluid is guided to the second pair of partition walls, and the inner partition walls of each of the second pair of partition walls further divide the flow path, whereby the flow path of the fluid is naturally and uniformly widened. Therefore, the fluid can be more uniformly discharged (sprayed) from the discharge side opening, and therefore, for example, when the reactant is sprayed in the chemical reaction step, the reaction efficiency can be made uniform, and the pesticide When sprayed, the drug effect can be made uniform. In the spraying nozzle according to claim 3, the opening area of the opening connected to the conduit of the dispersion cylinder and the opening area of the discharge side opening are formed to be substantially the same, and the spraying gas and the fluid are introduced into the dispersion cylinder. Since the flow velocity at the time of discharge is almost the same as that at the time of discharge, there is no sudden change in the cross-sectional area from the conduit side to the discharge side. It is possible to reduce the pressure loss due to the change of.
