Solar water-salt co-production device and manufacturing technology thereof

Abstract

The invention belongs to the field of sea water desalination, and particularity relates to a solar water-salt co-production device and a manufacturing technology thereof. The solar water-salt co-production device comprises a combined transparent shed cover, wherein one layer or a plurality of layers of heat absorbing gauze hoods are mounted in the combined transparent shed cover; a spraying device is mounted in each heat absorbing gauze hood; a spraying cleaner is mounted between each heat absorbing gauze hood and the combined transparent shed cover; a desalted water collecting tank and a rain water collecting tank are arranged at the connected position of the combined transparent shed cover and the ground, and the desalted water collecting tank and the rain water collecting tank are connected with a reservoir through water pipes. The solar water-salt co-production device realizes water-salt co-production of sea water desalination, rain water collection and yield increase of bay salt through solar energy utilization; the solar water-salt co-production device is high in utilization rate of light and heat, low in manufacturing cost, short in investment payoff period, and scientific and reasonable in designing conception, and therefore, the solar water-salt co-production device is suitable for large-scale industrial popularization; the solar water-salt co-production device provides a new path for carbon-free sea water desalination.

Description

technical field [0001] The invention relates to a solar water-salt cogeneration device and a manufacturing process thereof, belonging to the field of seawater desalination. Background technique [0002] Sun-dried salt is divided into two stages of process, namely evaporation and concentration and crystallization of salt. The area of ​​the evaporation pool and the crystallization pool in the salt pan is generally 8:2, and there are four factors that determine the efficiency of evaporation: sunlight resources, radiation intensity, wind convection, and environment. Temperature and humidity generally cannot be produced in the low-temperature winter in northern my country. In addition, on cloudy and rainy days, not only does it not evaporate, but precipitation can reduce the concentration of raw brine due to dilution. Heavy rain is the most sensitive issue in the sun-dried salt industry. [0003] Originated from solar desalination in the 15th century, a wide variety of technologic...

Problems solved by technology

[0003] Originated from solar desalination in the 15th century, a wide variety of technological methods have been developed to this day, all of which are in scientific research and testing. The reason why none of them can enter the market operation is that the passive type has low output, and the active type has large investment and high energy consumption.
