【発明の詳細な説明】 ［産業上の利用分野］ 本発明は空調用ダクトなどに設けられて空気流から水
滴を分離せしめる高速気流用エリミネーターに関するも
のである。The present invention relates to a high-speed air stream eliminator provided in an air conditioning duct or the like to separate water droplets from an air stream.
［従来の技術］ 空調装置などの空気流路中においては、種々の原因に
よって気流中に水滴が混入し、この結果、前記流路中に
空気と水滴との混合気体となって流れることがある。こ
の混合気体は、送風機あるいは流路に対して、下記のよ
うな障害を生じさせる原因となる。[Prior Art] In an air flow path of an air conditioner or the like, water droplets may be mixed in the air flow due to various causes, and as a result, a mixed gas of air and water drops may flow into the flow path. . This mixed gas causes the following obstacles to the blower or the flow path.
イ．吸入された混合気体の水滴は、送風機の羽根、羽根
車、ハウジングなどの内面に衝突し、いわゆる濡れ面現
象を生じて流路の内面に水膜を形成し、この水膜がダク
ト内に流れ込んで水濡れによる障害を引き起こす。I. The water droplets of the sucked mixed gas collide with the inner surfaces of the fan, impeller, housing, etc. of the blower, causing a so-called wetting surface phenomenon to form a water film on the inner surface of the flow path, and this water film flows into the duct. Causes damage due to water wetting.
ロ．送風機内で濡れ面現象を起こさず、気流にも吸収さ
れなかった水滴は、送風機の下流のダクト内で濡れ面現
象を発生し、同様の障害を引き起こす。B. The water droplets that do not cause the wetting surface phenomenon in the blower and are not absorbed by the air flow also cause the wetting surface phenomenon in the duct downstream of the blower and cause the same trouble.
このような水膜の発生を防止する手段として、従来、
特開昭55−13653号公報にあるようなエリミネーターと
呼ばれる装置が使用されている。As means for preventing the occurrence of such a water film, conventionally,
A device called an eliminator as disclosed in JP-A-55-13653 is used.
［発明が解決しようとする課題］ しかしながら、上記エリミネーターは、流路内に波板
を設け、この波板に衝突することにより気流中の水滴を
分離するものであるから、前記波板が流路抵抗となって
大きな圧力損失を生じるという問題がある。[Problems to be Solved by the Invention] However, since the eliminator is provided with a corrugated plate in the flow path and separates water droplets in the airflow by colliding with the corrugated plate, the corrugated plate is used as the flow path. There is a problem that it becomes resistance and causes a large pressure loss.
本発明は上記事情に鑑みてなされたもので、その目的
とするところは、可及的に小さな圧力損失で気流中の水
滴を分離、回収することを目的とする点にある。The present invention has been made in view of the above circumstances, and an object of the present invention is to separate and collect water droplets in an air stream with a pressure loss as small as possible.
［課題を解決するための手段］ 上記目的を達成するため、本発明は、水滴を含む混合
気体が流れる流路中に設けられ、直進しようとする混合
気体の方向を屈曲させる屈曲部と、この屈曲部の下流に
設けられた水切り装置とからなり、前記水切り装置は、
屈曲部の下流側に連なるダクトの内面の全周に設けられ
て内方へ突出することを特徴とするものである。[Means for Solving the Problems] In order to achieve the above object, the present invention provides a bent portion that is provided in a flow path through which a mixed gas containing water droplets flows and bends the direction of the mixed gas that is going straight. It consists of a drainer provided downstream of the bent portion, the drainer,
It is characterized in that it is provided on the entire circumference of the inner surface of the duct connected to the downstream side of the bent portion and projects inward.
［作用］ 上記構成によれば、送風機で発生した気流は、吐出の
直後に屈曲部の内面に衝突し、水滴が分離される。分離
された水滴は、屈曲部に内面に水膜となるが、その下流
側の水切り装置によりせき止められ、下流側へ流れるこ
とがない。[Operation] According to the above configuration, the airflow generated by the blower collides with the inner surface of the bent portion immediately after the discharge, and the water droplet is separated. The separated water drops form a water film on the inner surface of the bent portion, but are stopped by the water draining device on the downstream side thereof and do not flow to the downstream side.

向に向けられる。[Embodiment] Reference numeral 1 in FIG. 1A is a duct, and the duct 1 is provided at a discharge port of a blower 6 having an impeller 5. By the rotation of the impeller 5 of the blower, a straight airflow is generated as shown by an arrow 2, and this airflow collides with the inner surface of the duct 1 which is bent as shown in the figure. When the air flow is a mixed gas of air and water droplets, a water film 3 is formed on the inner surface of the duct 1 due to the collision. As a result, the air stream from which the water droplets have been separated is directed in the horizontal direction while changing the direction of the flow as shown by arrow 4.
前記ダクト１の下流には、水切り装置７が設けられて
いる。この水切り装置７は、第２図（ａ）あるいは第２
図（ｂ）のような構成となっている。A drainer 7 is provided downstream of the duct 1. This drainer 7 is shown in FIG.

さらに下流側への水の流れを阻止することができる。That is, in FIG. 2 (a), a pair of plates are projected from the inner surface of the duct 1 to form a water draining device to block the water film along the inner surface of the duct 1.
Further, the flow of water to the downstream side can be blocked.
また第２図（ｂ）にあっては、ダクト１が内面から外
方へ突出するように設けられた溝が水切り装置となり、
これにより、前述の場合同様に水膜が遮断される。In FIG. 2 (b), the groove provided so that the duct 1 projects outward from the inner surface serves as a drainer,
As a result, the water film is blocked as in the case described above.

Also in the case of a system having a propeller-shaped impeller 5, water droplets can be separated as in the case described above.

A device that sprays water droplets in the air flow path of an air conditioner or the like for cleaning air, controlling temperature, and humidity. Specifically, by spraying water droplets into the airflow flowing in the duct using a spray nozzle or the like to form a mixed flow with air, the air is washed and the temperature and humidity are controlled. The eliminator makes it possible to remove water droplets from the mixed stream.

ことがない。EFFECTS OF THE INVENTION As is apparent from the above description, in the present invention, since the bent portion is provided in the flow path of the blower, the air flow generated by the blower collides with the inner surface of the duct or the like due to the existence of the bent portion. The water drops are separated. The separated water drops form a water film on the inner surface of the bent portion, but the continuity of the water film is lost because the drainer protrudes inward or outward from the entire circumference of the inner surface of the duct on the downstream side. Therefore, water drops do not flow downstream along with the flow of air. Further, since the water droplets are separated by the bent portion which is almost inevitably present in the flow passage of the blower, no particular pressure loss is caused in the flow passage.
