The specific embodiment
Specify a kind of boats and ships involved in the present invention with reference to the accompanying drawings with eddy flow washer and emission gases processing method thereof.
Boats and ships according to the present invention comprise with the eddy flow washer: the cyclone body 20 that is formed by cylindrical portion and conus portion; The cyclone inflow portion 21 that is formed at the cylindrical portion of said cyclone body 20 and plays channeling flows into cyclone body 20 through said passage emission gases; Be formed at first nozzle 22 of said cyclone inflow portion 21; Be formed at second nozzle 23 of said cyclone body 20 cylindrical portion.
Cyclone (cyclone) is the separator that utilizes the centrifugal force that flows into the inner fluid rotation of cyclone and produce; For example the gas cyclone device is mainly used in solid particulate matter or the drop that is suspending in the divided gas flow, and separates according to the granularity of the solid particulate matter that is suspending in the gas or the difference of proportion.
As shown in Figure 2, cyclone body is formed by cylindrical portion 8 and conus portion 9 usually.It is inner that fluid gets into cyclone through the inflow portion that is formed at said cylindrical portion upper end, and the fluid that flows into the certain speed supply with the tangential direction of cylindrical portion sidewall.Through the inner eddy current that forms of said action cyclone; Make the big and bulky particle (solid particulate matter, drop etc.) of the density that contains in the fluid under centrifugal action, rotate and accumulate in conical walls, by the point one side discharging of the conus portion 9 that is called tip (Apex) or underflow nozzle 10.
In addition, the gas in the fluid together is gathered in the cyclone centre and forms the rising rotating vortex according to condition and density and the little particle of volume.This upwelling is by the pipeline underflow overflow detector that inserts cyclone cylindrical portion upper end 11 dischargings.
The wet scrubber that the present invention relates to is considered and need be installed in boats and ships; Adopt the minimum said cyclone mode of necessary seawater amount and space requirement amount; On said cyclone, effectively distribute a plurality of nozzles; And then give full play to the separating effect that utilizes said centrifugal force, and increase the reaction table area and the reaction time of water-soluble gas and water simultaneously to greatest extent, effectively handle emission gases by the boats and ships discharging.
Shown in Fig. 3 cyclone front elevation and cyclone side view shown in Figure 4; First nozzle 22 that is formed at cyclone inflow portion 21 is through reducing temperature of exhaust gas; Make gas such as SOx and sea water mixing rate and reactivity improve; Therefore inflow portion 21 can adopt all types nozzle that can form the curtain film, but should adopt fan nozzle (sector nozzle) for the temperature that reduces emission gases effectively.In addition,, plural first nozzle 22 should be installed, make inflow portion 21 form multiple seawater curtain film in order to bring into play its effect to greatest extent.
The emission gases of first nozzle 22 through being formed at said inflow portion 21 flows into cyclone body 20, and then in the inner rotation of cyclone.At this moment; Like the cyclone front view of Fig. 3 and shown in the cyclone side view of Fig. 4; Emission gases contacts with seawater from second nozzle 23 discharging that is formed at said cyclone body 20 cylindrical portion and reacts, and directly reacts with seawater in the process through the seawater curtain film that formed by said second nozzle 23.At this moment, be disposed to the outside with the underflow nozzle (underflow nozzle) of the aitiogenic seawater of emission gases through cyclone.
In addition; Washer according to the present invention can further include: be formed at body 20 cylindrical portion upper ends and be used to prevent the mist separator (demistor) 24 that mist (mist) is revealed, can be further from the emission gases of the seawater curtain film through second nozzle 23, thoroughly remove acid mist through this device.
In addition; The washer that the present invention relates to can also comprise: be connected to the saveall (economizer) 25 that said cyclone inflow portion 21 and emission gases inflow cyclone body play the heat-exchange device that reduces the gas temperature effect before in order to reduce the temperature of exhaust gas that flows into cyclone inside; Groove (batch tank) 26 in batches can also further be set in addition; Be used for keeping a certain amount of from the streamflow of said cyclone body 20 dischargings; And can be designed to, measure discharging running water level (head) within it, and discharging automatically under certain water level condition.
In addition, the boats and ships that the present invention relates to comprise the steps: to flow into cyclone inflow portion 21 with the emission gases processing method of eddy flow washer emission gases is through the first step of the multiple seawater curtain film that formed by first nozzle 22; Through the emission gases inflow cyclone body 20 of multiple seawater curtain film in the said first step and aitiogenic second step of seawater of discharging with second nozzle 23; And, with the third step of the aitiogenic emission gases of the seawater of said second step through the multiple seawater curtain film that forms by second nozzle 23.
Said processing method also comprises: said third step finishes the step of the emission gases of back through the multiple seawater curtain film that formed by second nozzle 23 through the mist separator (demistor) that is formed at the cylindrical portion upper end and is used to prevent that acid mist (mist) from revealing, makes through further thoroughly removal of the acid mist in the emission gases of seawater curtain film.
Said processing method also comprises: the step of the saveall (economizer) 25 of emission gases through playing the heat-exchange device effect before the said first step, can about temperature of exhaust gas more than 400 ℃ be reduced to below 150 ℃ through said saveall.Emission gases through saveall is disposed to the outside after through washer after seawater eroding drops to the state of cooling below 50 ℃.
At this moment; After said third step is accomplished; Also can further comprise, will be transferred to the step of said saveall (economizer) 25 again, make emission gases be circulated in heat-exchange device again from the emission gases of washer discharging; So not only can reduce the temperature of inflow gas, and can obtain to heat and then discharge with the state that buoyancy further increases to the gas of outside drain.
In addition; Said second step can be designed to; Discharge from said cyclone body 20 conus portions with the aitiogenic seawater of emission gases, flow into subsequently the discharge stream water yield is remained a certain amount of batch groove (batch tank) 26, make discharging flowing water under certain water level condition, discharge automatically.
Can be designed as through said processing method, the interior emission gases treatment process of boats and ships that does not need the device expert and not only be convenient to operation but also can control automatically, device inside does not need other auxiliary equipments such as cooling device simultaneously, and convenient for maintenance management is simple.
The invention is not restricted to described specific embodiment and explanation; The personnel that possess general knowledge in the technical field in the main idea of the present invention that in this claim scope, requires under this invention all can carry out various distortion to it and implement, and this type distortion case all is contained in protection scope of the present invention.
