Description

Desalination ship based on sea sand desalting automatic discharging

Technical field

The present invention relates to sea sand desalting technical field, it particularly relates to a kind of based on the light of sea sand desalting automatic discharging Change ship.

Background technology

At present, China's year production m3 of cement concrete about 2,500,000,000, plus mortar and other purposes, it is annual need 3,000,000,000 tons with On building sand.As the river sand resource of the concrete fine aggregate contradiction that supply falls short of demand.Many places have gone out The situation of existing river (river) sand scarcity of resources；Meanwhile to prevent the exhaustive exploitation of river (river) sand to natural landscape and ecological environment band Carry out heavy damage, various regions gradually take measures to be any limitation as.

In order to solve river sand imbalance between supply and demand, people have invested eye the ocean for taking up an area sphere area 70.8%, reasonable development Have become a selection being difficult to avoid that using sea sand resources.

Building generally can't do without armored concrete, still, corrosion of the reinforcing steel can be caused to become rusty containing substantial amounts of villaumite in sea sand, The passivating film of rebar surface is wrecked, and then corrosion cell is formed in rebar surface, produce electrochemical corrosion, reinforcing bar is continuous Corrosion product caused by corrosion can produce tensile stress around reinforcing bar, when running up to certain, can make because volume increases 4~7 times Peeling or reinforcing bar cracking into concrete cover；Sulfate in sea sand can generate aquation sulphur aluminic acid in concrete pore Calcium, cause the spalling and peeling of concrete；Sea sand contains the materials such as shell, can substantially reduce the workability of concrete, influence to mix Coagulate tension, anti-folding, the mechanical property such as compression strength of soil, the endurance quality such as the frost resistance of concrete, wear resistence, impermeability has Reduced, or even can also influence the volume stability of concrete；Sea sand contains the alkali such as the mineral matters such as opal, flint and sodium, potassium Metal, concrete is caused to produce alkali-aggregate reaction, so that the durability of concrete structure and security reduce；

Also make the intensity decreases of concrete containing harmful substance, these content of material Gao Shihui such as sulphur and phosphorus in sea sand.

In order to improve the antidetonation compression strength of building, the desalination of sea sand be using sea sand be used in architectural engineering must be through Step.Conventional sea sand desalting handling process belongs to bank base processing, all processing technological flows, including go mud, go shell stone, Desalination etc., realized in bank base, gathered in sea sand and transport bank process, almost without any processing links, produced ask therewith Topic：Its cost is higher, first has to set a larger place, to meet the requirement of processing sea sand or half light salty sand, it is necessary to enter Row infrastructure construction；Secondly, sea sand or half light salty sand are from obtaining from underwater installation, transport to place and usually require to have enough to meet the need, every time Turnover all unavoidably adds operating cost.There is specific requirement in place, and satisfactory place is not necessarily close to engineering institute On ground and production zone, the soaring of cost of transportation is caused.Again, the disposal of impurity produced by bank base technique.

Therefore, existing people has by aboard ship being desalinated, and desalted sea sand is compared with land on ship, the restraining factors that are subject to It is more, to realize that desalted sea sand is much more difficult on ship, the bearing capacity for desalinating ship is also one of restraining factors, while will desalination Sea sand be transferred to cargo ship, transfer and difficult point, transfer is improper, and cargo ship easily causes rollover.
