Abstract

The invention discloses an apparatus and a method for desalinating sea sands. The apparatus comprises a recycled water production system and a sea sand desalination system, the recycled water production system least comprises a reclaimed water pool, a reclaimed water purification and desalination system and a recycled water storage tank which are sequentially connected, and reclaimed water from the reclaimed water pool is treated by the reclaimed water purification desalination system and then is stored in the recycled water storage tank; and the sea sand desalination system least includes a sea sand inactivation membrane breaking system and an impurity removal vibrating screen device, a first-stage sand washer, a second-stage sand washer and a third-stage sand washer which are sequentially arranged, the first-stage sand washer is connected with the reclaimed water pool, and the second-stage sand washer and the third-stage sand washer are respectively connected with the reclaimed waterstorage tank. The sea sand desalination apparatus uses reclaimed water or desalinated seawater as raw materials to desalinate sea sands, so freshwater resources are saved, and the sea sand desalination cost is reduced.

Description

technical field [0001] The invention relates to a sea sand desalination device and method. Background technique [0002] With the over-exploitation of natural sand and gravel resources and the government's high attention to the protection of the ecological environment, the price of sand and gravel aggregates has shown a trend of skyrocketing in recent years, and some areas even have no sand to buy. Many people have begun to use sea sand. Prepare concrete. However, the surface of sea sand will contain a large amount of chloride, so sea sand contains a large amount of chloride ions, which seriously exceeds the standard for construction sand, and it will seriously corrode and damage the steel bars inside the concrete when used in engineering construction. Structure of reinforced concrete. In addition, sea sand also contains other harmful impurities, such as: shells, silt, mica, light matter, organic matter, and sulfide. Shells, mica, and light substances reduce the bond of a...
