Description
Technical field
The present invention relates to a kind of sea sand desalting device and methods.
Background technique
Great attention with the exhaustive exploitation and government of natural sand stone resource to ecological environmental protection, this several years sandstones
The trend that rises suddenly and sharply is presented in the price of aggregate, the awkward situation that can be bought without sand even occur in some areas, and many people start with sea sand preparation
Concrete.But sea sand surface can contain a large amount of chloride, so sea sand contains a large amount of chloride ion ingredient, it is serious
Standard beyond building sand destroys steel for that can have serious corrosiveness in engineering construction to the reinforcing bar of inside concrete
The structure of reinforced concrete.In addition, sea sand also contains other objectionable impurities, such as: shell, mud, mica, light materials, organic
Object, sulfide.Shell, mica and light materials can reduce the cohesive force of aggregate and cement and building stones in concrete.Therefore, country is bright
Enable: sea sand is directly used in prestressed concrete without must not desalinate.Sea sand is to be only second to the second largest ocean mine of petroleum gas
It produces, if its desalting is used, can solve the disparities between supply and demand of natural sand stone resource.In recent years, the desalination of sea sand
Desalination technology and application are by attention.Standard is utilized for specification sea sand desalting, according to China " construction sand " (GB/T14684-
2011) standard, country have promulgated " building and municipal works purification sea sand " (JG/T 494-2016) standard, standard regulation: have built
If a kind of sand chloride ion content used in sand must not exceed 0.001%, two classes must not exceed with sand chloride ion content
0.005%, and the three classes sand of minimum requirements, chloride ion content also must not exceed 0.01%.Currently, sea sand desalting mainly use it is light
Water cleaning, desalting makes sea sand by three-level cleaning, desalting (i.e. level-one cleaning, desalting, second level cleaning, desalting and three-level cleaning, desalting)
Salt content drop to 0.001% hereinafter, to meet " construction with sand " standard, it is light using this method using fresh water washing
Change sea sand, one ton of sea sand of every desalination will at least consume 1.2 tons of fresh water, and therefore, desalted sea sand needs a large amount of freshwater resources.Mesh
Before, China major part coastal area, scarcity of fresh water resources.But middle water and seawater resources are abundant, therefore, if in capable of using
Water or seawater are raw material desalted sea sand, will be a kind of good selections.Therefore, it is badly in need of water or sea water desalination sea sand in a kind of utilization
Device and method.

It is connected to the water outlet of the first order sand washer and the second level sand washer, the water inlet of the three-level washed-out sand effluent settling chamber
Mouth is then connect with the water outlet of the third level sand washer, and the three-level washed-out sand effluent settling chamber water outlet is connected to described three
Grade washed-out sand wastewater collection pond, the water outlet of the three-level washed-out sand wastewater collection pond and the pond Zhong Shui are interconnected.
Preferably, the sludge outlet of the firsts and seconds washed-out sand effluent settling chamber and the three-level washed-out sand effluent settling chamber
It is connected to a sludge-tank, the sludge-tank and a sludge dehydration device, which are attached, to carry out being dehydrated into clod,
Preferably, the sludge dehydration device can be centrifugal dehydrator, plate and frame filter press, folded spiral shell dewaterer or pocket type dehydration
One of machine.
Preferably, the middle Water warfare desalination system includes pre-filtrating equipment and counter-infiltration system, the pre-filtrating equipment
Including the first filter device and the second filter device, first filter device includes more Jie successively connecting with the pond Zhong Shui
Mass filter and active carbon filter, second filter device are one of micro-filtration, ultrafiltration, MBR or nanofiltration.
The present invention also provides a kind of sea sand desalting device, including seawater desalination system and sea sand desalting system, institutes
It states seawater desalination system and includes at least sequentially connected seawater water intake well, seawater cleaning desalination system and sea water desalination water basin,
The seawater of the seawater water intake well is stored in sea water desalination water basin after seawater cleaning desalination system processing；The sea
Sand desalting system then includes at least sea sand inactivation the rupture of membranes system, impurity elimination vibrating screen device, first order washed-out sand set gradually
