Abstract
The present invention discloses a kind of method of seawater desalination, it is possible to decrease the salinity of sea water so as to can be used for industrial application, auxiliary product can do agricultural fertilizer.
Description
Technical field
The present invention relates to a kind of method of seawater desalination, belongs to field of environment protection.
Background technology
Cities and towns, agricultural and industry are increasing to the demand of water, and deficient in many regional waters in the world.The disabled reason of sea water is that existing desalination method is not only slow but also difficult and cost intensive, needs big energy containing salt.Worldwide energy consumption is continuously increased, and these energy are produced by combustion oil, coal gas, wood and other organic substances, are thus polluted the environment.Environmentalist all over the world advises reducing the existing yield of carbon dioxide (CO2) and the discharge capacity to air, to protect the environment against the destruction of the greenhouse effect caused by CO2.Many countries all reduce the discharge capacity of the CO2 of this country with the formal compulsion of regulation.
The content of the invention
A kind of method of seawater desalination, which is characterized in that：First metered catalyst ammonia NH3 and sea water mixing.Ammonia is easy to be mixed to form NH4OH with water, containing very active reactant molecule.They have very strong suction, and the CL atoms of molecules of salt in sea water are won over.
Second step is to will be enriched in CO2 burning waste gas in a sealing treatment intracavity being located on depositing reservoir to import by the entrance of side and stay in intracavity for processing procedure.Remaining gas are left from the outlet of opposite side.Sea water is pumped into into processing chamber, and the mist dispersion blocking from some charging apertures near top.CO2 gas molecules are drawn to the Na atoms of salt, further reduce the internal bond of molecules of salt in vaporific sea water and dissociate which.Two kinds of heavy solids are formed, they settle in depositing reservoir and remove in underflow outlet.Salt per ton has a large amount of desalinated seawater overflows and goes out depositing reservoir, because 3% salt is only existed in sea water.Then can be using the desalinated seawater as commercial water, water for industrial use and agricultural water；The ammonia also dissolved containing some in the desalinated seawater and plankton and other organisms, are other halobiontic nutrients in ocean, and these nutrients are also acted as agrological fertilizer.Salt is dissociated and two kinds of solids of carbon dioxide eliminating process are the sodium carbonate Na2CO3 that proportion the is 2.53 and ammonium chloride NH4Cl that proportion is 1.53.Two kinds of solids can be separated by hydraulic cyclone, airslide conveyor and nebulization or other means.
Can include that top board and the processing chamber of cylindrical wall are implemented with one in the present inventive method, be the depositing reservoir for having a cylindrical wall being connected with the conical lower portion with sump below；Feed pipe with the outlet of some dispersed sprays provides the sea water mixed with ammonia；Burning waste gas containing CO2 are supplied to processing chamber by air inlet pipe；Remaining waste gas is removed by escape pipe；The sea water of desalination is removed by downflow weir and overflow pipe；Splash-back and annular overflow cover will trap and splash the water of desalting process is continued；Underflow is removed from sump by pipe type conveyer by air injection, and the air of injection is mixed with the material of sump and makes which lighten and spray to enter separator, and air is removed from the top of separator.
