Evaporation and desalination of sea water in salt field and rainwater recovery device

Abstract

The invention provides a salt field seawater evaporation desalting and rainy water recycling apparatus. The salt field seawater evaporation desalting and rainy water recycling apparatus consists of a fixed column, a pull rope, a positioning clamp, a suspension plate, a pull rod, a spring fixing plate, a return spring, a supporting rod, a supporting shaft, a rain collection evaporation cover, an external water collection trough plate, an internal water collection trough plate, a fixed clamping trough, a flow water pipe and a recycling water collection pipe. The salt field seawater evaporation desalting and rainy water recycling apparatus has the advantages that the rain collection evaporation cover is arranged above a salt field, the temperature in the salt field is increased and not influenced by the rainfall, the evaporation amount is increased, and fresh water and rainy water formed by condensing steam in the evaporation cover are collected by virtue of the recycling water collection pipe; the positioning clamp is arranged on a take-up and payoff rope, so that the flow water pipe can be accurately inserted into the recycling water collection pipe after the rain collection evaporation cover is laid down, and the quantity of the rain collection evaporation covers can be increased or reduced according to the size of the salt field.

Description

technical field [0001] The invention belongs to equipment for recovering water in a salt field, in particular to a device for evaporating and desalinating seawater in a salt field and recovering rainwater. Background technique [0002] Yantian sea is one of the methods of making salt from seawater. The process of making salt includes steps such as moisture collection, brine making, crystallization, salt mining, storage and transportation. Solar evaporation is a very old method of salt production, and it is also a common method still in use. This method is to build many ponds like rice fields on the bank for drying salt. The process of making salt includes steps such as moisture collection, brine making, crystallization, salt mining, storage and transportation. To receive tides is to store seawater with high salinity in the repaired salt pans. Brine production is to use solar energy to evaporate seawater, and the concentration gradually increases. When the water evaporate...
