Technical field
The present invention relates to sea water desulfuration field, in particular to boats and ships seawater desulfurization device.
Background technology
Sea water desulfuration is to remove SO in flue gas using natural sea-water as absorbent
2wet Flue Gas Desulfurization Technique, be a key areas of direct seawater utilization.This technology is taught the sixties in last century and is proposed at first by the Bromeley.A of California, USA Berkeley University.
In correlation technique, the boats and ships of operation at sea, it generally all can be provided with diesel engine, boiler etc., therefore, can produce a large amount of sulfur-containing smoke gas; For the consideration of environmental protection aspect, a large amount of flue gases of generation need could discharge after desulfurization.
In correlation technique, for a large amount of sulfur-containing smoke gas that produce on boats and ships, common processing method is directly to wash with seawater, the equipment of realizing this washing methods mainly contains that void tower absorbs and packed tower absorbs two classes, and the desulfurization treatment facility of lifting all needs at right angle setting, highly reach several meters even tens meters and can not jolt.And for boats and ships and offshore work platform, it is difficult to the installing space that provides such, therefore, this device is not obviously suitable for diesel engine and the boiler fume desulfurizing and dedusting on boats and ships.
In addition, in correlation technique, because seawater is not pass through any processing, directly carry out the washing of oil-contg. smoke with it, so, in the process of washing, need very large liquid-gas ratio (10-40L/M
3) just can reach good clean result; And then the pump that seawater also just need to be provided has sizable discharge capacity, this operation obviously can increase the energy consumption of whole desulfurization operations.Further, limited, therefore slower with the reaction speed of flue gas without the contact-making surface that goes out seawater itself and sulfur-containing smoke gas of any processing, and then the time that makes the process of whole desulfurization to continue to grow, and desulfuration efficiency is not high.
In sum, in correlation technique, common desulphurization plant is due to defects such as the installing space that exists equipment to need are large, energy consumption is large and desulfurized effect is poor, it is not suitable as boats and ships seawater desulfurization device, therefore, providing a kind of seawater desulfurization device that is applicable to boats and ships flue gas is this area technical problem urgently to be resolved hurrily.

2+, Mn
2+deng trace metal ion to SO
2absorption also have certain facilitation.Wherein, SO in reaction temperature and flue gas
2concentration depend primarily on the actual conditions of flue gas.
The natural basicity of seawater is also the principal element that affects desulfuration efficiency.The normal range (NR) of seawater pH value is between 7.3-8.6.Contained a large amount of CO in seawater
3 2-and HCO
3 -be to control the principal element of seawater pH value, thereby this system has the buffer capacity that larger anti-positive value changes, this is the key of flue gas desulfurization with seawater.SO in flue gas

In addition, in order to increase the amount of the sour gas in Absorption by Sea Water flue gas; Preferably, can carry out electrolytic treatments to seawater, so, in the present embodiment, also comprise for being input to the seawater electrolysis device 202 of described seawater input pipe 106 seawater electrolysis before.
The liquor natrii hypochloritis who produces when electrolytic seawater.Clorox has strong oxidizing property, can be oxidized SO

2o.In carrying out above-mentioned neutralization reaction, in seawater, blast large quantity of air and carry out aeration, its effect mainly contains: (1) is by SO
3 2-be oxidized into SO
4 2-; (2) utilize its mechanical force by a large amount of CO that produce in neutralization reaction
2drive the water surface out of; (3) dissolved oxygen of raising desulfurization seawater, qualified discharge.
In this technology due to seawater when the electrolysis by H
+electron gain changes into hydrogen, has ensured that the pH value of sea water solution maintains certain alkalescence value NaCl+H
2o electrolysis=NaClO+H
2↑, and H
2gas can remove and directly discharge from solution.
Therefore, by by seawater electrolysis, it can produce the NaClO with strong oxidizing property on the one hand, it can be oxidized to low price sulphur high price sulphur, be beneficial to conversion and the absorption of flue gas, meanwhile, the seawater after electrolysis is easy to maintain its alkalescence, be convenient to flue gas in sour gas generation neutralization reaction, and then make seawater after electrolysis be suitable as very much the desulfurizing agent of sulfur-containing smoke gas.
In addition, in the present embodiment, the buck producing in sweetening process is discharged by the buck outlet 109 that is arranged on hollow columnar shell 101 bottoms, and in there is the part between rotating disk 104 and hollow columnar shell 101 in rotating shaft 103, therefore, in order to prevent that buck after desulfurization is in contact with it and then affects its rotating effect.Preferably, in the technical scheme of the present embodiment, on described hollow columnar shell 101 inner side diapires, be also provided with for the described rotating shaft in described hollow columnar shell 101 103 is overlapped to the cone-shaped hood 203 of wrapping up in; The cross section of described cone-shaped hood 203 is along gradually little to the direction of described rotating disk 104 from described inner side diapire.
In addition, for the ease of controlling the amount of the seawater that enters whole desulfurizer, preferred, the part of described seawater input pipe 106 outside described hollow columnar shell 101 is also provided with a control valve 204.
In the further technical scheme of the present invention, pending flue gas, before entering desulfurizer, also can be processed dedusting and flue gas cool-down, therefore, in the present embodiment, also comprises that one for treating smoke treatment rough dusting and cooling preprocessor 205; In addition, be operation effectively, in system composition, go back inclusion test and alarm unit (not shown).This unit has flue-gas temperature, flow, sulfur-bearing dust-laden and flue gas pressures degradation and detects (Check processing front end and processing rear end respectively), the function that seawater flow, temperature, pH value and operating pressure etc. detect.
Please refer to Fig. 2, before flue gas enters desulfurizer machine, the preprocessor 205 of flue dust is mainly used in rough dusting and flue gas cool-down.Work seawater can be introduced preprocessor 205 completing before cooling discharge outboard by the low-temperature cooling water of the central refrigerated sea water system of diesel engine (main frame or generating set).
The volume ratio of seawater and flue gas is at 1.5 to 3.0 liters of seawater/cube flue gases.Pretreated flue gas enters in desulfurizer and under the effect of hypergravity, fast and effeciently carries out heat and mass transport process with seawater, simultaneously under the effect of centrifugal force, buck is separated, and discharge by the buck outlet 109 of bottom, through purify flue gas (flue gas now should reach discharge standard) by the processing at top after flue gas discharge opening 108 discharge, as flue gas after treatment does not reach discharge standard, detecting unit automatic transfer ceases and controls alarm unit and report to the police, heighten seawater pH value by controlling seawater pH value regulon (seawater electrolysis device 202) action.
In the process of work, seawater is provided by special sea water pump, and the volume ratio of seawater and flue gas is got between 0.8 to 1.5 conventionally, depends primarily on pH value and the ocean temperature of seawater.If the pH value of seawater is too low, can open seawater pH value regulon, namely seawater electrolysis device 202 improves the pH value of seawater.The seawater ratio that enters seawater pH value regulon by the regulation of control and regulation valve 204, this ratio is between 25% to 35%.
The key of the present embodiment is to be that reasonable combination seawater electrolysis and desulfurization are in a system, reach optimal desulfurization and dedusting effect thereby configure effect that appropriate technical parameter brings into play separately each assembly, and the cost of device and the scope of the expense of operation in reasonable economy.
