Abstract

太陽熱吸収板としてコンクリートを用い, ポーラスシートと平行細線溝を海水蒸発面に応用した液膜蒸発式屋根型海水淡水化装置を試作し, 性能評価と操作条件に関して以下のようなことがわかった.<BR>1. 供給液流量は, シートの飽和液流量から15kg・h<SUP>-1</SUP>・m<SUP>-1</SUP>までの流量域で淡水生産量に著しく影響を及ぼしたが, 15kg・h<SUP>-1</SUP>・m<SUP>-1</SUP>を越えると影響は小さくなった.<BR>2. シート蒸発表面積がメニスカス表面積より大きいとき, 淡水生産量が急激に増加した.<BR>3. シート内が不飽和液分布となる流量域では, 蒸発面のドライアウトやスケール発生のおそれがあるため, 供給液流量の最適な操作範囲は, FsからFuまでの範囲がのぞましい.

A solar still using a concrete slab as a solar collector was developed. Brine was filmwisely fed into the grooves of parallel polyethylene ropes under the slab onto which a porous sheet was attached. The production of distillate depended strongly on the feed rate divided into three liquid flow rate regions: dry-out, effective, and independent. The result of simulation with respect to meniscus film flow shows that the mechanism of heat transfer is due to the surface area ratio of the sheet to the meniscus film.
