Embodiment

[0036] 1. There are two ways to desalinate desalination ice:

[0037] The first is the icing rink on dry land, which uses the flat land in winter to build an ice rink on the impermeable ground. Irrigation and drainage pipes are designed at the bottom. The depth of irrigation is determined by the thickness of the ice harvested, generally 12-16cm. When the ice layer is 10cm thick, the brine is drained, the ice is cut, and the ice is packed into bags (food packaging plastic bags) for storage.

[0038] The second method is the pit pond ice rink. Fill the pond with more than 60-100cm of water. When the thickness of the ice is more than 10cm, the ice is cut and collected, and the remaining water continues to freeze until 2 / 3 of the total water volume is collected. Ice harvesting—cutting according to ice storage standards, and storing in bags (food packaging plastic bags) after initial treatment. The advantage of this method is that old pits and ponds can be used. The disadvantage i...

Abstract

The method capable of utilizing natural cold source to make ice for desalinating brackish water includes the following steps: A. utilizing winter atmospheric temperature when which reach to below zero deg.C to make brackish water or sea-water in the artificial or natural pool be iced; B. when the ice layer is coagulated to 2-3 cm, water in the bottom portion can be discharged, the water level can be lowered so as to form negative pressure filtration hollow cavity, utilizing temperature difference between day and night to make ice layer be repeatedly molten and frozen; C. using plastic bag to pack ice block and store the ice blocks in icehouse; and D. placing the primarily-desalinated ice block in ice-melting pool whose lower portion is equipped with water-discharging hole, discharging firstly-molten saline ice water and retaining residual desalinated water.

Description

technical field [0001] The invention relates to a method for making ice and desalinating brackish water by using a natural cold source and related equipment, belonging to the technical field of water resources utilization and water quality treatment. Background technique [0002] The shortage of fresh water resources is a worldwide common problem. China is a water-scarce country, especially in the north. In the Bohai Rim Economic Zone, fresh water has seriously restricted the development of industry and agriculture, and the drinking water quality of residents in many counties and villages is not up to standard. At present, the surface water has decreased sharply, and the shallow water is bitter and salty, relying on the annual overexploitation of 200-400 million m 3 The deep groundwater used to maintain people's lives and national economic development has caused serious environmental problems. On the other hand, these areas are near the sea, and there is a large amount of ...
