A multi-energy-driven seawater salt production tower and salt production process

Abstract

The invention provides a multi-energy-driven seawater salt producing tower, and belongs to the technical field of seawater salt producing. The salt producing tower is sequentially provided with a tide absorbing pond, a first evaporation pond, a second evaporation pond, a primary bittern making pond, an intermediate-level bittern making pond, a high-level bittern making pond, a crystallizing pond and a salt storage pond from bottom to top. The pond bottoms of the evaporation ponds, the bittern making ponds and the crystallizing pond are provided with electric heaters, and the tops of the upper spaces of the ponds are provided with distilled water collecting devices. The salt producing tower is driven by multi-energy power and comprises a solar power generation device, a wind power generation device and a hydraulic potential power generation device, and renewable resources are fully utilized. According to the salt producing tower, all the technological link ponds for coastal sunlight salt extraction are stereoscopically overlaid, the solar energy, wind energy and distilled water draining potential are utilized to generate power, the power is supplied to the electric heaters to heat seawater to accelerate evaporation for salt producing, the mud flat space occupied by coastal sea surrounding salt extraction is significantly saved, the working efficiency of seawater salt producing is effectively improved, a large amount of distilled water can be produced, energy conservation and environment protection are achieved, and the comprehensive utilization efficiency of the seawater is improved.

Description

technical field [0001] The patent of the present invention relates to a multi-energy-driven seawater salt production tower, which mainly uses solar energy, wind energy, hydraulic potential energy to generate electricity and other energy sources to drive electric heaters to heat the device for seawater evaporation and salt production in different layers of pools in the tower, which belongs to the technology of seawater salt production field. Background technique [0002] In coastal tidal flat sea-salting operations, the coastal tidal flats are surrounded by sea-sun-dried salt process ponds of different sizes and shapes, such as tide pools, evaporation ponds, brine making ponds, crystallization ponds, and salt storage ponds. The seawater in the pond is evaporated in the sun, and the salinity of the water body in the pond is gradually increased to form high-salinity brine. When the high-salinity brine is further evaporated to saturated salinity, it crystallizes into sea salt ri...

AI Technical Summary

Problems solved by technology

This sea salt process method mainly relies on sunlight and increases the sea salt area around the tidal flats to produce sea salt products, which has low operating efficiency, occupies a large area of ​​tidal flats, is easily affected by weather such as heavy precipitation, and has low production efficiency.
