Desalination assembly has transparent outer and non-translucent inner concentric pipes

摘要

An assembly using solar energy produces clean water, esp. for the irrigation from dirty water or salt water. The novelty is that: (a) the assembly has a section (3) consisting of a transparent outer (6) and non-translucent inner (4) concentric pipe; (b) dirty water or salt water passes through the inner pipe, which bears perforations (5) along its upper face through which water vapour escapes; (c) the side and lower faces of the outer pipe (6) has a pipe-shaped jacket (8) through which cold dirty water or salt water flows; (d) the lower face of the outer pipe (6) has perforations (13) through which condensed water drips to the surface (13) under irrigation through a water-absorbing and distribution mattress (14) made of a natural fibre such as flax or hemp, which minimises subsequent evaporation losses from the surface (13), and (e) before entering the inner pipe (4) the water passes through a dark-coloured solar collector (2).
