ルに関する。[Detailed Description of the Invention] [Field of Industrial Application] The present invention can be used in a wide range of applications, such as cooling red-hot steel plates and roller conveyors that convey them, or spraying chemicals on crops in vegetable gardens and orchards. The present invention relates to a flat spray type gas-liquid mixing spray nozzle that has many uses.

In this type of gas-liquid mixing spray nozzle, Fig. 9,
As shown in FIG. 10, the bottomed cylindrical nozzle body 01
A tapered curved inner circumferential surface 01a is formed on the inner bottom of the nozzle body 01 so as to be concentric or almost concentric with the nozzle axis P. A slit-shaped orifice 02 is formed along orthogonal or substantially orthogonal directions.

次のような問題があつた。 When using this nozzle, the nozzle body 01
Although the mixed gas liquid can be sprayed over a wide range in a flat state from the orifice 02 by flowing the mixed gas liquid guided along the curved inner circumferential surface 01a and colliding at the center of the curved inner circumferential surface,
I had the following problem:
即ち、混合気液がオリフイス０２から霧化噴出

霧気液の厚み方向で相対向する面がノズル軸芯Ｐ
１と平行に構成されているため、混合気液の噴霧
膜厚方向での噴霧角がどうしても小さくなる。
That is, when the mixed gas liquid is atomized and ejected from the orifice 02, it is affected by the expansion action of the compressed gas and the diffusion action by the negative pressure at the tip of the orifice, forming a spray film perpendicular to the spray width direction. Although it is also diffused in the thickness direction, the surfaces of the orifice 02 that face each other in the thickness direction of the atomized gas and liquid are aligned with the nozzle axis P.
1, the spray angle of the mixed gas and liquid in the spray film thickness direction inevitably becomes small.
それ故に、混合気液の噴霧幅を所定の幅に維持

度が高くなり、その結果、例えば、製鉄所での赤
熱鋼板の冷却設備において、弱冷が要求される赤

の使用範囲が自ら限定される問題がある。 Therefore, when trying to maintain the spray width of the mixed gas/liquid at a predetermined width, the liquid volume density of the sprayed gas/liquid in the film thickness direction increases, and as a result, for example, in cooling equipment for red-hot steel plates in steel plants, When cooling a red-hot steel plate that requires weak cooling, it tends to cause overcooling, and there is a problem that its range of use is self-limited.

その作用・効果は次の通りである。
The technical means of the present invention taken to achieve the above object is to form a tapered curved inner circumferential surface on the inner bottom of the bottomed cylindrical nozzle body, concentrically or almost concentrically with the nozzle axis. In the gas-liquid mixing spray nozzle, the bottom of the nozzle body is formed with a slit-shaped orifice extending in a direction perpendicular or substantially perpendicular to the nozzle axis. , a spray guide surface extending along the longitudinal direction of the orifice is formed in a portion connected to the periphery of the orifice, and the spray guide surface is formed as an outwardly expanding surface that becomes farther from the nozzle axis toward the downstream side in the direction of spraying the mixed gas liquid. It is in the point that
Its actions and effects are as follows.

When the mixed gas liquid is atomized and ejected from the orifice in a flat state, the mixed gas liquid is flow-guided along the spray guide surface connected to the orifice forming surface, and the spray film thickness direction intersects with the longitudinal direction of the orifice. It is also relatively widely diffused to the outside.

た。
Therefore, by changing the formation angle of the spray guide surface, the spray angle in the spray film thickness direction can be freely changed while maintaining the same spray width as before, so it can be adjusted to various spray conditions. Accordingly, it is possible to provide a nozzle that can spray with a spray width and a spray film thickness adapted to each condition. Moreover, the above-mentioned effects can be achieved with a simple modification of forming the above-mentioned spray guide surface at the tip of the nozzle body.
