example 1

[0150] like Figure 5 The configuration shown has an evaporation unit and a condensation unit with a height of 12 meters and a diameter of 75 cm for desalination of brine. The evaporation unit and condensation unit consist of five evaporation / condensation zones. Seawater input temperature and evaporation area temperature are as follows:

[0151] Input hot salt water 85℃

[0152]Zone 1 (uppermost) 76°C

[0153] Section 2 70°C

[0154] Section 3 64°C

[0155] Section 4 57°C

[0156] Section 5 (bottom) 52°C

[0157] Results obtained from operating the above unit under these conditions demonstrate that a distilled water output in excess of 18,000 liters per 24 hours can be achieved. The water quality was measured using a standard conductivity meter and the total dissolved solids level was found to be less than 20 ppm.

Abstract

The invention discloses a method and equipment for purifying fluid. An evaporation unit (10) and a condensation unit (110) are employed. Each unit has a chamber (12, 112) and a plurality of spaced apart breaker plates (18, 118), each plate spanning at least a portion of the width of the chamber and each defining either an evaporation zone (20) or a condensation zone (120) upper limit. Each evaporation zone (20) is provided with a fluid vapor outlet (32), and each condensation zone is provided with a fluid vapor inlet. The evaporating and condensing zones operate at different temperatures. The fluid vapor outlet of the evaporating zone (20') operating at the highest temperature is connected to the fluid vapor inlet of the condensing zone (120") operating at the highest temperature, while the fluid vapor of the evaporating zone (20") operating at the lowest temperature The steam outlet is connected to the fluid steam inlet of the condensing zone (120') operating at the lowest temperature.

Description

technical field [0001] The present invention relates to methods and equipment for purifying fluids, in particular to evaporation / condensation units useful in fluid purification and desalination / purification methods using these units. Background technique [0002] There is an increasing shortage of fresh water globally. Freshwater consumption is growing at a faster rate than economic growth, yet the availability of traditional freshwater supplies has remained essentially unchanged. 97% of the water on earth exists in the form of salt water. Therefore, finding energy-efficient and environmentally friendly desalination methods is an important challenge to solve the global freshwater shortage. [0003] More recently, attempts to improve desalination technology have focused on incremental improvements to existing technologies. Generally speaking, there are two broad categories of desalination techniques. The first category is membrane-based technologies, such as reverse osmos...
