The system includes a body having a bottom portion configured to be situated inside the liquid in the pond and an upper portion extending upward outside the liquid; at least one conveyor mounted on said body and including an evaporation surface, the conveyor is configured to move the evaporation surface along a rotary path extending between the bottom portion and the upper portion; wherein the evaporation surface includes a mesh having a plurality of pores each of which configured to entrap a droplet of liquid; and wherein the conveyor is configured to continuously rotate the evaporation surface along the rotary path, between the bottom portion in which pores entrap droplets of liquid from the evaporation pond and the upper portion such that the droplets evaporate when traveling along the rotary path.

This invention discloses a solar greenhouse salt-making device, specifically relating to the field of salt production technology. It includes an evaporation tank, a translucent top cover, capillary suction blocks, and a fan. The translucent top cover is detachably connected to the evaporation tank and completely covers its opening. An inlet pipe is located at the end of the evaporation tank furthest from the top cover, allowing brine to enter the tank. The capillary suction blocks are placed inside the evaporation tank, with their bottoms submerged in the brine. The capillary action of the blocks causes the brine to move to their top. A ventilation hole is located on the side wall of the evaporation tank near the top cover, situated at the top of the capillary suction blocks. A fan is fixedly installed within the ventilation hole and electrically connected to a wind power generation device. This invention improves brine evaporation efficiency, shortens the salt-making production cycle, and increases economic benefits.

This invention provides an evaporation tank for wastewater treatment and a method for preparing lithium carbonate, relating to the field of wastewater treatment technology. An evaporation tank for wastewater treatment includes: a tank body, on which an injection pipe and a discharge pipe are respectively provided, and a heat-absorbing evaporation plate is fixedly installed inside the tank body; a condenser hood, the bottom of which covers the top of the tank body, the condenser hood having through holes, and a drainage groove fixedly installed inside the condenser hood. A method for preparing lithium carbonate includes the following steps: Step S1, introducing raw brine into the evaporation tank for wastewater treatment, where the evaporation tank evaporates and concentrates the brine to obtain concentrated brine. The heat-absorbing evaporation plate and the heat exchange pipe not only improve the efficiency of wastewater evaporation but also improve the condensation efficiency of water vapor on the inner wall of the condenser hood after evaporation. The condensed water can be recycled into a water circulation tank, realizing the recycling of water resources.

This invention discloses a method for seawater desalination based on solar energy distillation, belonging to the field of seawater desalination technology. The method involves injecting pretreated seawater into an evaporation tank, where it remains stationary. A convex lens above the evaporation tank focuses sunlight to form a spot, which passes through a light-transmitting enclosed cover and illuminates a high-thermal-conductivity metal heat-absorbing plate inside the evaporation tank, heating it to 400–600°C. A small amount of seawater in the evaporation tank is then lifted to the surface of the heat-absorbing plate using capillary adsorption, forming a thin liquid film of 0.5–2 mm. Upon contact with the high-temperature surface, the liquid film undergoes flash evaporation, generating water vapor. The water vapor condenses into fresh water on the inner wall of the light-transmitting enclosed cover and is collected. When the seawater in the tank is concentrated to 1 / 5–1 / 3 of its original volume, brine and impurities are discharged, and the process is repeated for the next cycle. This invention effectively solves the technical problem of heat loss during focused heating, preventing the formation of effective boiling. Using solar energy as a heat source, it achieves green seawater desalination with zero energy consumption and zero carbon emissions. The process is simple and easy to promote.
