【考案の詳細な説明】
本考案は多段フラッシュエバポレータ等に用いるフラッ
シュ蒸発装置に関する。[Detailed Description of the Invention] The present invention relates to a flash evaporation device used in a multistage flash evaporator or the like.
多段フラッシュエバポレータは初段の蒸発室より下段の
蒸発室に向うに従い順次減圧された多段の蒸発室より構
成されている。A multi-stage flash evaporator is composed of multiple evaporation chambers in which the pressure is sequentially reduced from the first evaporation chamber to the lower evaporation chamber.
従来の初段以外の蒸発室は第１図に示すように蒸発室８
相互間に差圧を生成するためのオリフィス１．ブライン
ミストを分離するデミスタ２１発生蒸気を凝縮するコン
デンサ３．およびコンデンサ３にて凝縮して淡水とされ
た蒸留液を貯留する溜箱７を具えている。The conventional evaporation chamber other than the first stage is evaporation chamber 8 as shown in Figure 1.
Orifices 1. to create a pressure difference between them. Demister 21 to separate brine mist; condenser 3 to condense generated steam; and a storage box 7 for storing distilled liquid that has been condensed into fresh water in the condenser 3.
しかし、オリフィス１から噴出したブラインが蒸発室８
内に滞留する時間は限られていてブラインが十分蒸発せ
ずに次の蒸発室に出て行ってしまう欠点があった。However, the brine spouted from orifice 1
There was a drawback that the time the brine remained in the chamber was limited, and the brine would not evaporate sufficiently and would flow out to the next evaporation chamber.
本考案は上記欠点を解消するために提案されたものであ
って、以下１本考案を第２図□よび第３図に示す１実施
例により説明する。The present invention has been proposed to solve the above-mentioned drawbacks, and one of the present invention will be explained below with reference to an embodiment shown in FIGS. 2□ and 3.
第２図および第３図において、１はオリフィス２はブラ

ブラインがブライン溜り９に流れおちるようにそれぞれ
勾配を有している。2 and 3, 1 is an orifice; 2 is a demister for separating brine mist; 13 is a condenser for condensing generated steam; 4, 5, and 6 are brine receiving plates according to the present invention; Plate 4, second brine receiving plate 5. The third brine receiving plates 6 are arranged in this order so as to face each other at intervals, and each has a slope so that the brine flowing down the upper surfaces thereof flows into the brine reservoir 9.
７はコンデンサ３によす凝縮された蒸留液の溜箱、８は
蒸発室である。7 is a storage box for the distilled liquid condensed to the condenser 3, and 8 is an evaporation chamber.
しかして、オリフィス１より噴出したブラインの１部は
第１ブライン受板４．第２ブライン受板５、第３ブライ

って緩やかに流下し、上方のブライン受板上□落下した
ブラインは順次その下方のブライン受板、を流下してブ
ライン溜り９に溜る。A portion of the brine ejected from the orifice 1 is transferred to the first brine receiving plate 4. The brine falls onto the upper surfaces of the second brine receiving plate 5 and the third brine receiving plate 6 and slowly flows down in the form of a thin film along the slope. It flows down the receiving plate and collects in the brine reservoir 9.
このブライン受板４，５，６を通過時にブラインは十分
な滞留時間を与えられフラッシュ蒸発するこ−ととなる
。When passing through the brine receiving plates 4, 5, and 6, the brine is given sufficient residence time to undergo flash evaporation.
また、このブライン受板４，５゜６はブライン溜り９よ
りのブラインの飛散をさえぎるので、ブラインと発生蒸
気との衝突により生じるブラインの再飛散が減少しコン
デンサ３へのブラインの混入による蒸留水の純度の低下
を阻止できる。In addition, since the brine receiving plates 4, 5 and 6 block the scattering of brine from the brine reservoir 9, re-scattering of brine caused by collision between brine and generated steam is reduced, and distilled water caused by mixing of brine into condenser 3 is reduced. can prevent a decrease in purity.
以上述べた様に本考案は、上記蒸発室内において上記オ

で未蒸発プラインが生じない。As described above, in the present invention, at least one brine receiving plate is provided in the evaporation chamber at a position facing the orifice at an angle, so that the brine spouted from the orifice is not received by the brine receiving plate. Since the brine flows down slowly over the plate, the residence time of the brine in the evaporation chamber can be extended, and sufficient flash evaporation can be promoted, so that no unevaporated prine is generated.
