Problems solved by technology

[0002] As we all know, the seawater evaporation method is used to dry salt from seawater, and all of them use planar evaporation. The main way to increase production is limited to the planar area of ​​the salt field. However, the efficiency of this method of planar salt drying is limited.

Embodiment

[0022] This example is spray sun salt experiment.

[0023] Experimental conditions: air temperature 22°C, relative humidity 70%, wind force level 4, spraying is carried out at the leeward side of the house facing the sun. Before spraying, the specific gravity of the salt water is 10° (1.10), the diameter of the nozzle is 1.5 mm, the height of the nozzle is 0.5 m, the nozzle is facing upwards, and the spray pressure is 2 standard atmospheres, and it is operated with an agricultural sprayer.

[0024] Experimental process: When the agricultural sprayer sprays salt water to a height of 0.5 meters or more, small mist-like water droplets fall on the ground in 5 areas with an area of ​​116cm 2 In the plastic box, accept the salt water 240 milliliters / hour box after the spray of specific gravity is 11 °; It is 46 milliliters that 10 ° of salt water is sun-dried and made specific gravity is the salt water of 11 °, in other words, every box (area 116cm 2 ) can only be dried to obtain ...

Abstract

The spraying salt-sunning method features that under 1.5-2.5 atm, brine is conveyed via stem pipe and branch pipes and sprayed to air via the nozzles to form fogy water drops, and the said process is repeated until required concentration is reached. In the production process, two kinds of different nozzles and multilayer spraying are used, and yield as high as 5 times that of available method may be obtained.

Description

technical field [0001] The invention belongs to the technology of liquid evaporation, more precisely, it relates to a method for producing salt by salt spray evaporation. Background technique [0002] As we all know, the seawater evaporation method is used to dry salt from seawater, and all of them use planar evaporation. The main way to increase production is limited to the planar area of ​​the salt field. However, the efficiency of this planar method of drying salt is limited. Contents of the invention [0003] The purpose of the invention is to improve the existing sun-drying salt technology and propose a method for spraying sun-dried salt. [0004] The main technical scheme and principle of the present invention: under a certain pressure, the salt water is sprayed into the air through the nozzle, so that the continuous water flow becomes fine water droplets and forms an atomized state. Then these water droplets are sprayed to the ground. Since the sprayed water drople...
