上記従来の二重噴霧塔では、塩水噴霧を休止している間に、塩水ノズルや空気ノズルの先端部に塩が析出し、ノズルを詰まらせることがある問題点があった。
他方、上記従来の噴霧塔装置では、塩の析出による塩水ノズルや空気ノズルの詰まりを防止できたが、垂直塔の内部に設置する場合について全く配慮されていない問題点があった。
そこで、本発明の目的は、塩の析出による塩水ノズルや空気ノズルの詰まりを防止できると共に複数のノズルを垂直塔に対して容易に着脱可能とした噴霧塔装置を提供することにある。 The conventional double spray tower has a problem in that salt is deposited on the tip of the salt water nozzle or the air nozzle while clogging the salt water and the nozzle is clogged.
On the other hand, the conventional spray tower apparatus can prevent clogging of the salt water nozzle and the air nozzle due to salt precipitation, but there is a problem that no consideration is given to the case where it is installed inside the vertical tower.
Accordingly, an object of the present invention is to provide a spray tower apparatus that can prevent clogging of salt water nozzles and air nozzles due to salt precipitation and that allows a plurality of nozzles to be easily attached to and detached from a vertical tower.

A salt water nozzle (3) for supplying salt water to an inner space and a lower space of the spray amount adjuster (2), and a salt water nozzle which is installed below the tip of the salt water nozzle (3) and jets air vertically upward. An air nozzle (4) that blows up the salt water supplied from the nozzle (3) in a mist form, and is installed facing the salt water nozzle (3) toward the salt water nozzle (3) and the air nozzle (4). A water washing nozzle (5) for spraying washing water, a hood (6) for integrally holding the salt water nozzle (3) and the air nozzle (4), the air nozzle (4) and the water washing nozzle (5) and a block (7) for integrally holding the salt The nozzle (3), the air nozzle (4), the water washing nozzle (5), the hood (6), and the block (7) can be attached to and detached from the vertical tower (1) as an integrated object. A spray tower apparatus (100, 200) is provided.
In the spray tower apparatus according to the first aspect, salt is deposited on the tip of the salt water nozzle or the air nozzle by spraying wash water (fresh water or salt water) from the water wash nozzle toward the salt water nozzle and the air nozzle. Or the precipitated salt can be washed away. Therefore, clogging of the salt water nozzle and the air nozzle due to salt precipitation can be prevented. In addition, the salt water nozzle, air nozzle, and water washing nozzle can be easily attached to and detached from the vertical tower. Further, the spray range can be adjusted by opening the hood. Moreover, the air nozzle and the water washing nozzle to which the pressure of air or washing water is applied can be firmly supported by the block.

図１は、実施例１に係る噴霧塔装置１００の構成を示す断面図である。
この噴霧塔装置１００は、垂直に立てられた円筒体である垂直塔１と、垂直塔１の上端に設置された噴霧量調整器２と、垂直塔１の内部空間で且つ噴霧量調整器２の下方空間に塩水を供給する塩水ノズル３と、塩水ノズル３の先端の下方に設置され垂直上方に空気を噴出して塩水ノズル３から供給された塩水を霧状にして吹き上げる空気ノズル４と、塩水ノズル３に対向して設置され塩水ノズル３および空気ノズル４に向けて洗浄水（真水または塩水）を吹き掛ける水洗浄ノズル５と、塩水ノズル３と空気ノズル４とを一体的に保持するフード６と、空気ノズル４と水洗浄ノズル５とを一体的に保持するブロック７と、塩水ノズル３の尾端と垂直塔１の底部に設けた塩水溜部１ｃとを連結する吸上管８とを具備している。 Example 1
FIG. 1 is a cross-sectional view illustrating a configuration of a spray tower apparatus 100 according to the first embodiment.
The spray tower apparatus 100 includes a vertical tower 1 that is a vertically standing cylinder, a spray amount adjuster 2 installed at the upper end of the vertical tower 1, an internal space of the vertical tower 1, and a spray amount adjuster 2. A salt water nozzle 3 for supplying salt water to a lower space of the air nozzle, an air nozzle 4 installed below the tip of the salt water nozzle 3 and ejecting air vertically upward to blow the salt water supplied from the salt water nozzle 3 into a mist, A water cleaning nozzle 5 that is installed opposite to the salt water nozzle 3 and sprays cleaning water (fresh water or salt water) toward the salt water nozzle 3 and the air nozzle 4, and a hood that integrally holds the salt water nozzle 3 and the air nozzle 4. 6, a block 7 that integrally holds the air nozzle 4 and the water washing nozzle 5, and a suction pipe 8 that connects the tail end of the salt water nozzle 3 and the salt water reservoir 1 c provided at the bottom of the vertical tower 1; It has.

図２に示すように、塩水ノズル３と空気ノズル４と水洗浄ノズル５とフード６とブロック７とは一体物であり、噴霧塔用ミストノズル１０と呼ぶ。噴霧塔用ミストノズル１０は、垂直塔１に対して着脱可能である。   As shown in FIG. 2, the salt water nozzle 3, the air nozzle 4, the water washing nozzle 5, the hood 6, and the block 7 are integrated and are referred to as a spray tower mist nozzle 10. The spray tower mist nozzle 10 is detachable from the vertical tower 1.

図１に戻り、垂直塔１の側壁の開口部１ａにブロック７を取り付けたとき、開口部１ａに対向する側壁に穿設した貫通孔１ｂから塩水ノズル３の尾端が突出する。この塩水ノズル３の尾端に吸上管８を接続する。また、空気ノズル４の尾端には圧縮空気管Ａを接続し、水洗浄ノズル５の尾端には洗浄水管Ｗを接続する。   Returning to FIG. 1, when the block 7 is attached to the opening 1 a on the side wall of the vertical tower 1, the tail end of the salt water nozzle 3 protrudes from the through hole 1 b formed in the side wall facing the opening 1 a. A suction pipe 8 is connected to the tail end of the salt water nozzle 3. A compressed air pipe A is connected to the tail end of the air nozzle 4, and a washing water pipe W is connected to the tail end of the water washing nozzle 5.

塩水噴霧時は、洗浄水は止めておく。そして、塩水溜部１ｃに例えば５％塩濃度の塩水を溜めておき、空気ノズル４から圧縮空気を吹き出す。これにより、塩水ノズル３から塩水が吸い出され、垂直上方へ塩水霧が吹き上げられる。塩水霧は、垂直塔１と噴霧量調整器２の間の隙間（図には垂直塔１への噴霧量調整器２の取付柱の断面が表れており、隙間は表れていないが、取付柱の部分以外は隙間になっている）から側方へ噴出される。噴霧量調整器２の高さを調節することにより、噴霧量を調整できる。   Stop washing water when spraying with salt water. Then, for example, salt water having a salt concentration of 5% is stored in the salt water reservoir 1c, and compressed air is blown out from the air nozzle 4. Thereby, salt water is sucked out from the salt water nozzle 3 and salt water mist is blown up vertically upward. The salt water mist is a gap between the vertical tower 1 and the spray amount adjuster 2 (the cross section of the mounting column of the spray amount adjuster 2 to the vertical tower 1 is shown in the figure, and the gap is not shown. It is ejected to the side. The spray amount can be adjusted by adjusting the height of the spray amount adjuster 2.

水洗浄時は、圧縮空気は止めておく。そして、水洗浄ノズル５から洗浄水（真水または塩水）を吐出する。これにより、塩水ノズル３や空気ノズル４の先端部に塩が析出するのを防止できるか又は析出した塩を洗い流すことが出来る。   Stop compressed air when washing with water. Then, cleaning water (fresh water or salt water) is discharged from the water cleaning nozzle 5. Thereby, it can prevent that salt precipitates on the front-end | tip part of the salt water nozzle 3 or the air nozzle 4, or can wash away the deposited salt.

実施例１の噴霧塔装置１００によれば、次の効果が得られる。
（１）水洗浄ノズル５からノズル３，４に向けて洗浄水を噴き掛けることにより、ノズル３，４の先端部に塩が析出するのを防止できるか又は析出した塩を洗い流すことが出来る。よって、塩の析出によるノズル３，４の詰まりを防止できる。
（２）塩水ノズル３や空気ノズル４や水洗浄ノズル５を一体化物として垂直塔１に対して容易に着脱可能になる。
（３）フード６により、不要な方向への塩水霧の飛散および洗浄水の飛散を防止することが出来る。

(1) By spraying washing water from the water washing nozzle 5 toward the nozzles 3 and 4, salt can be prevented from being deposited on the tip portions of the nozzles 3 and 4, or the deposited salt can be washed away. Therefore, clogging of the nozzles 3 and 4 due to salt precipitation can be prevented.
(2) The salt water nozzle 3, the air nozzle 4 and the water washing nozzle 5 can be easily attached to and detached from the vertical tower 1 as an integrated object.
(3) The hood 6 can prevent splashing of salt water mist and washing water in unnecessary directions.
(4) The air nozzle 4 and the water cleaning nozzle 5 to which the pressure of the air or the cleaning water is applied can be firmly supported by the block 7.

この噴霧塔装置２００は、ポンプＰにより塩水溜部１ｃから塩水を吸い出し水洗浄ノズル５に供給する点以外は、実施例１の噴霧塔装置２００と同じ構成である。 -Example 2-
FIG. 3 is a cross-sectional view illustrating a configuration of a spray tower apparatus 200 according to the second embodiment.
The spray tower apparatus 200 has the same configuration as the spray tower apparatus 200 of the first embodiment except that the salt water is sucked out from the salt water reservoir 1c by the pump P and supplied to the water washing nozzle 5.

図４に示すように、塩水ノズル３と空気ノズル４と水洗浄ノズル５とフード６とブロック７とは一体物であり、噴霧塔用ミストノズル１０と呼ぶ。噴霧塔用ミストノズル１０は、垂直塔１に対して着脱可能である。   As shown in FIG. 4, the salt water nozzle 3, the air nozzle 4, the water washing nozzle 5, the hood 6, and the block 7 are integrated, and are called a spray tower mist nozzle 10. The spray tower mist nozzle 10 is detachable from the vertical tower 1.

実施例２の噴霧塔装置２００によれば、実施例１と同じ効果に加えて次の効果が得られる。
（４）噴霧する塩水と同じ塩水を洗浄水として用いるので、噴霧する塩水の濃度が変動することを防止できる（真水を洗浄水として用いると、塩水溜部１ｃの塩水濃度が低下してしまう）。 According to the spray tower apparatus 200 of the second embodiment, the following effects can be obtained in addition to the same effects as the first embodiment.
(4) Since the same salt water as the salt water to be sprayed is used as the wash water, it is possible to prevent the concentration of the salt water to be sprayed from fluctuating (if the fresh water is used as the wash water, the salt water concentration in the salt water reservoir 1c is reduced). .

本発明の噴霧塔装置は、例えば塗装の腐食性を試験するのに利用できる。   The spray tower apparatus of the present invention can be used, for example, to test the corrosivity of a coating.
