Description
Technical field
The utility model relates to a kind of boats and ships desulfurizing waste water processing device, belongs to boats and ships desulfurization wastewater process field.
Background technology
According to MARPOL pact supplemental provisions VI regulation, on January 1st, 2015 rises, and navigation is at the ship of emission control district (ECA), must combustion of sulfur amount be equal to or less than 0.10%(m/m) low sulphur fuel oil, allow ship to use the emission-reduction technology through ratifying simultaneously, condition is SO
2discharge is equivalent to burning and is equal to or less than 0.10% low sulphur fuel oil.
Because petroleum resources are in short supply, low sulphur fuel oil price is high and supply falls short of demand, and marine exhaust desulfurization becomes domestic and international study hotspot.The marine exhaust desulfurizer discovery that investigation has been reported at present both at home and abroad, except Couple Systems company adopts dry desulfurization, all the other are wet desulphurization.Visible wet desulphurization is the main way of marine exhaust desulfurization, adopts Wet Flue Gas Desulfurization Technique will inevitably produce desulfurization wastewater.And strict regulation has been done to the washing water discharge index of marine exhaust cleaning system by International Maritime Organizaton (IMO).Owing to being marine exhaust desulfurization, its desulfurization wastewater discharge is subject to again the restriction of < < Pollution From Ships thing emission standard > > simultaneously.Therefore the processing of desulfurization wastewater, is indispensable gordian technique in whole wet method marine exhaust desulphurization system.Marine exhaust desulfurization technology belongs to emerging technology, and research emphasis mainly concentrates on the raising of desulfuration efficiency and the reduction of energy consumption at present, and the research of processing about marine exhaust desulfurization wastewater is less.Investigate existing domestic and international marine exhaust desulfurizer, rarely have the detailed introduction of desulfuration waste water treatment process.Waste water is just oxidized by simple aeration or cyclonic separation is discharged or reuse after processing.
Magnesium base-seawater method (M & S) is a kind of efficient marine exhaust sulfur method.Waste gas enters thionizer and spray liquid contact reacts, the pollutent in gas, as: particulate matter (PM), SO
2, NO
2deng part, by spray liquid, absorbed, form fluid contaminants.Wherein a PM part suspends in water, and another part dissolves and forms polycyclic aromatic hydrocarbons (PAHs); Unburnt oil fuel enters into waste water with waste gas, total increased the oil-contg of waste water; SO
2water-soluble and with sweetening agent in Mg
2+reaction generates indissoluble thing MgSO
3; NO
2formation NO soluble in water
2 -and NO
3 -.PH value, COD, turbidity are (mainly by MgSO
3and PM contribution), total oil, PAHs, NO
x -be the pollutent that requires control in discharge index.
To sum up, in this area, lack complete M & S method marine exhaust desulfurizing waste water processing device.
Summary of the invention
The utility model, by a kind of new device of invention, has solved desulfurization wastewater emission problem.
The utility model provides a kind of boats and ships desulfurizing waste water processing device, described device comprises retort, pump I, microbubble generator, valve, pump II, ejector, cyclone separator and adsorption column, the outlet I of described retort is connected with one end of microbubble generator by pump I, the other end of microbubble generator is connected with the entrance I of retort, the outlet II of retort is connected with one end of pump II by valve, the other end of pump II is connected with cyclone separator by ejector, ejector is provided with flocculation agent feeding mouth, the liquid waste outlet of cyclone separator is connected with adsorption column.
Microbubble generator described in the utility model is preferably with air compressor and is connected.
The flocculation agent feeding mouth of ejector described in the utility model is preferably with flocculation agent storage tank and is connected.
The solid waste outlet below of cyclone separator described in the utility model is preferably and is provided with sludge sump.
The utility model is for the MgSO in desulfurization wastewater
3and NO
2 -, the method that adopts microbubble aeration to be oxidized, is oxidized to MgSO
4and NO
3 -, COD and the turbidity of reduction water, alleviate the load that follow-up cyclonic separation is processed; By flocculation agent, improve the suspended substance particle diameter in waste water, to improve the efficiency of cyclonic separation; For the PAHs in water and total oil, adopt the method for adsorption column absorption to process.
The utility model beneficial effect is for the different pollutents in desulfurization wastewater, adopts different treatment processs, forms the method for wastewater treatment of complete M & S method marine exhaust desulphurization system; Control pollutent in marine exhaust washes discharge index is removed effectively, realized desulfurization wastewater qualified discharge; Guarantee the reliable and stable operation of apparatus for desulfurizing exhaust gas.
