Abstract
The invention relates to a technology for preparing high yield ecological salt by utilizing solar energy. The technology is characterized in that a crystal wind tunnel is arranged; a crystal salt growth pool is arranged below the crystal wind tunnel; a preheating and presaturation well brine pool and a recrystallization treating pool are arranged on the two sides of the crystal wind tunnel; the preheating and presaturation well brine pool, the recrystallization treating pool and the crystal wind tunnel are covered with a solar heat collection greenhouse; the crystal wind tunnel is internally provided with a crystal cloth array; the solar heat collection greenhouse provides a hot wind source; and high-temperature misty brine is adhered to and wets the cloth array, and is revaporised to generate the salt which grows continuously after adhered to cloth. Mist flows under the action of hot wind, and enters a condensation chamber at the tail part of the crystal wind tunnel to promote separation of vapor and the brine. Therefore, the misty brine absorbed by the cloth array in the crystal wind tunnel continuously loses water and is crystallized to form the salt, like a plane salt pan; the salt loses the water to be crystallized; a salt crystal forms a pile growing continuously under the action of heat brine atomization and the hot wind, and falls in the crystal salt growth pool at the lower end of the cloth array to continuously grow under the action of gravity and external force when a certain amount of the salt crystal is gathered. The technology is environment-friendly and high-yield, fields can be adjusted according to local conditions, and land resources are saved.
