Description
Ocean engineering power tail gas of the present invention only uses seawer washing purification method and device, suitable for the high-temperature tail gas purification of the ocean engineerings power facility such as marine ship, ocean platform discharge, belongs to field of ocean engineering.
In the past 20 years, as global environment resource problem becomes increasingly conspicuous, the atmosphere pollution based on sulfur dioxide is caused for the ocean engineerings facility power exhaust emissions such as marine ship, ocean platform, the international legislation managed is stringent year by year, the United Nations's International Maritime Organization (IMO) (IMO) carries out the low-sulfur decree of prevention and treatment ship atmosphere pollution, wherein there are ship Low Sulfur Fuel Oil regulation and Low Sulfur Fuel Oil substitution regulation.In view of that largely will cause the basic reasons such as high cost and high carbon emission using Low Sulfur Fuel Oil, people thirst for always low cost, the seawer washing purification process of low-carbon emission for a long time, can become the green practical art of substitution Low Sulfur Fuel Oil as early as possible.Seawer washing purification process, that is seawater EGC (Exhaust Gas Clean) technique, also referred to as " NSW EGC ", " OSW EGC " etc., (Only) seawer washing motor exhaust is only used in principle, washing draining through prior art simple process can be discharged into sea and to marine eco-environment close friend, therefore can be with atmosphere pollution of the Ultra Low Cost efficient emission-reducing ocean engineering power facility based on sulfur dioxide.Meanwhile the promotion that modern marine engineering requires safety and health operating environment, so that people is growing on and on the expectation of seawer washing purification process functionization.
But in the prior art, such as China Patent No. shown in fig. 5 is ZL 200920065586.4, the technical solution of entitled " a kind of dust removal integrated washer of flue gas desulfurization with seawater suitable for offshore platform operation ", Conventional processing methods and device by thermoelectricity field using alkali chemicals as washing medium, it is diverted to occasion of the ocean engineering field using seawater as washing medium, is had the following problems:
1) sulfur dioxide absorption is ineffective, and pollution emission reduction does not reach requirement, and the environmental protection for losing the emission reduction of seawer washing process efficient is excellent
Gesture.This is primarily due to the dedicated spray column of thermoelectricity field traditional handicraft, and the mass transfer intensity when washing medium is changed into seawater is greatly lowered.
It 2) is improvement assimilation effect, it has to increase seawater spraying density, while increase tail gas resistance again, in addition conventional washing arrangement cannot directly handle engine high-temperature tail gas, must separately set tail gas precooler and consumption precools water.These all increase operation energy consumption and maintenance cost, and seawer washing technique is caused to lose the economic advantages of low cost.
3) bulky, it can only hang outside cabin, cabin, cannot achieve on-line operation (On Line).
Such technical solution, there are also some to improve assimilation effect, have to add alkali chemicals in seawer washing system, the technical characteristic of Only seawater is lost instead, and the advantage to marine eco-environment close friend, cause environmental economy cost soaring, as a result become to be forbidden discharging by most sea area and the technique that is not available.
Separately or concurrently there is the prior art of problem above and disadvantage, the practical art of substitution Low Sulfur Fuel Oil could not be become, also fails to play and extinguish the safe and healthy and environment-friendly functions such as Mars, elimination thermal pollution and purification flue dust.
Such as Chinese patent of Patent No. ZL 200880129628.4 again, disclose the technical solution for only carrying out padding washing purification with seawater to ocean engineering power facility tail gas, but due to more tentatively, having caused further expectation of the people to promoting, optimizing such technical solution.

A kind of ocean engineering power tail gas of the invention is only described further with seawer washing purification method and device in conjunction with the accompanying drawings and embodiments as follows.
Embodiment 1: being the basic embodiment that a kind of ocean engineering power tail gas of the present invention only uses seawer washing purification method, as shown in attached drawing 1,2,3a, 3b, 4, implementation steps include motor exhaust and seawater are imported to wash mill, in wash mill with seawer washing tail gas, by the cleaning of off-gas and washing seawater discharge wash mill after washing；It is characterized in that, described is the padding washing carried out in padding washing device by packing layer with seawer washing tail gas in wash mill, the padding washing device includes the packing layer that the filler stem factor is 10~2000/m, and the time that tail gas passes through the packing layer is 0.05~20 second.The filler stem factor (Factor) is a/ ε3, unit is 1/m, and wherein a is total specific surface area of packing layer, and unit is m2/m3, ε is the ratio of packing layer voidage and packing layer volume, and unit is m3/m3。
The main distinction of the prior art representated by the technology of the present invention route and attached drawing 5, attached drawing 6:
First is that, the present invention uses padding washing technology path, it is because the dissolution reaction of seawer washing technique needs biggish gas-liquid contact face, and the packed tower that packing factor is big, packing layer specific surface area are also big, can provide the dissolution gas liquid interfacial area that reaction needs, but packing factor is excessive, can because resistance greatly caused by the excessive influence engine operating condition of back pressure, and the effect of padding washing is also influenced by wash time, for this purpose, the present invention proposes the parameter of the suitable fillers factor and wash time.
The display of the prior art shown in Fig. 5 is using the dedicated spray column of traditional sulfur removal technology；Traditional sulfur removal technology does not have to packed tower generally, gradually abandons the early stage such as packed tower of Fig. 6 one kind packing factor very little yet, is because alkaline industrial chemicals is easy to fouling blockage, it is necessary to using the hollow spray column of gas-liquid contact face very little；Obviously, by the dedicated spray column of traditional sulfur removal technology, packed tower, it is diverted to seawer washing technique, it is bad to will result in sulfur dioxide assimilation effect.
It is washed second is that the engine high-temperature tail gas that temperature is 200 DEG C to 500 DEG C is introduced directly into packing layer by wash mill of the present invention, thus cost and operating cost are low, run more reliable.The prior art shown in attached drawing 5, because its traditional handicraft washing unit cannot directly handle engine high-temperature tail gas, it is necessary to which precooler, the consumption precooling water of tail gas are set, so that volume increases, manufacture and operating cost are increased, reliability decrease.
Third is that the present invention is due to high-efficient, small in size, it is easy to accomplish wash mill is integrated with motor silencer, becomes the practical art with ocean engineering power facility on-line operation；Prior art shown in attached drawing 5 is difficult to realize greatly on-line operation due to low efficiency, volume.
