Industrial salt solarization harvesting process

Abstract

The invention discloses an industrial salt solarization harvesting process, which belongs to a method for preparing halides. The salt harvesting process of the invention comprises the five steps of brine change in a crystallizing pond, six-point salt collection, salt conveyance with new brine, manual salt sprinkle and impurity removal. The harvesting process of the invention has the advantages of reducing the impurity content of industrial salts in harvesting operation, improving the quality of the industrial salts, changing crystal sizes and crystal growth environment, enlarging industrial salt particles, reducing equipment loss and energy consumption and reducing the damages of machines to the salt particles and the crystallizing pond.

Description

technical field [0001] The invention relates to a method for preparing halides, in particular to a beach-drying industrial salt collection process suitable for salt collection by a salt collection machine combined with water conservancy pipeline transportation and washing. Background technique [0002] The traditional beach-drying industrial salt collection process is: drain the brine in the crystallization pool to be collected, collect salt at three points, mix and collect the salt slag in the crystallization pool, leave seed crystal particles for industrial salt growth at will, and low-quality saturated brine Salt feeding, ballast leveling and homogenization by salt collector, and manual demixing process. [0003] The specific process steps are to first drain the brine in the salt crystallization pool to be collected, divide the salt collection area into upper, middle and lower areas, set the salt collection point in the center of each area, and then use the salt collectio...

AI Technical Summary

Problems solved by technology

[0004] In the traditional salt collection process, the collected industrial salt particles cannot be washed in high-quality brine (brine with a sodium-magnesium ratio of 3-6), so the impurity content of industrial salt is high

During three-point salt mining, the working radius of the salt collector is 40m, and the repeated rotation seriously damages the industrial salt particles, and increases the fuel consumption and maintenance costs of the salt collector

The particle size of industrial salt seeds left after harvesting is uneven, which affects the growth rate of crystals; Seriously affected the quality of industrial salt, increased production and increased harvesting costs of industrial salt
