Detailed description of the invention
Describe with reference to the accompanying drawings a kind of boats and ships eddy flow washer and emission gases processing method thereof involved in the present invention in detail.
Boats and ships according to the present invention comprise with eddy flow washer: the cyclone body 20 being formed by cylindrical portion and conus portion; The cyclone inflow portion 21 that is formed at the cylindrical portion of described cyclone body 20 and plays channeling, flows into cyclone body 20 by described passage emission gases; Be formed at the first nozzle 22 of described cyclone inflow portion 21; Be formed at the second nozzle 23 of described cyclone body 20 cylindrical portion.
Cyclone (cyclone) is the separator that utilizes the centrifugal force that flows into the fluid rotary of cyclone inside and produce, for example gas cyclone device is mainly for separating of the solid particulate matter suspending in gas or drop, and separates according to the difference of the granularity of the solid particulate matter suspending in gas or proportion.
As shown in Figure 2, cyclone body is formed by cylindrical portion 8 and conus portion 9 conventionally.Fluid enters cyclone inside by the inflow portion that is formed at described cylindrical portion upper end, and the fluid flowing into certain speed supply with the tangential direction of cylindrical portion sidewall.By the inner eddy current that forms of described action cyclone, large and the bulky particle (solid particulate matter, drop etc.) of the density that contains in fluid is rotated under centrifugal action and be gathered in conical walls, by the point one side discharge of conus portion 9 that is called tip (Apex) or underflow nozzle 10.
In addition, the gas in fluid is together gathered in cyclone centre and forms rising rotating vortex according to condition and density and the little particle of volume.This upwelling is discharged by the pipeline underflow overflow detector 11 that inserts cyclone cylindrical portion upper end.
The wet scrubber the present invention relates to is considered and need to be installed in boats and ships, adopt the described cyclone mode of necessary seawater amount and space requirement amount minimum, on described cyclone, effectively distribute multiple nozzles, and then give full play to the separating effect that utilizes described centrifugal force, increase to greatest extent reaction table area and the reaction time of water-soluble gas and water, effectively process the emission gases of being discharged by boats and ships simultaneously.
Shown in cyclone side view as shown in Fig. 3 cyclone front elevation and Fig. 4, the first nozzle 22 that is formed at cyclone inflow portion 21 is by reducing temperature of exhaust gas, the gases such as SOx and sea water mixing rate and reactivity are improved, therefore inflow portion 21 can adopt all types nozzle that can form curtain film, but should adopt fan nozzle (sector nozzle) in order effectively to reduce the temperature of emission gases.In addition, in order to bring into play to greatest extent its effect, plural the first nozzle 22 should be installed, make inflow portion 21 form multiple seawater curtain film.
The emission gases of the first nozzle 22 by being formed at described inflow portion 21 flows into cyclone body 20, and then at cyclone internal rotating.Now, as the cyclone front view of Fig. 3 and as shown in the cyclone side view of Fig. 4, emission gases contacts and reacts with the seawater discharging from the second nozzle 23 that is formed at described cyclone body 20 cylindrical portion, and directly reacts with seawater in process by the seawater curtain film that formed by described second nozzle 23.Now, be disposed to outside with the aitiogenic seawater of emission gases by the underflow nozzle (underflow nozzle) of cyclone.
The second nozzle 23 that is formed at described cyclone body 20 cylindrical portion for increasing seawater in the time of staying of cyclone inside and reaction table area is maximized, conventionally can adopt all types of nozzles that can form at cyclone body seawater curtain film, but in order to make the increase maximum effect of reaction time and reaction table area, should adopt mist nozzles (fog nozzle).And, for maximum effect, plural second nozzle 22 should be installed and make cyclone body 20 cylindrical portion form multiple seawater curtain film.
In addition, washer according to the present invention can further include: be formed at body 20 cylindrical portion upper ends and the mist separator (demistor) 24 for preventing that mist (mist) from revealing, can further from the emission gases of the seawater curtain film by second nozzle 23, thoroughly remove acid mist by this device.
In addition, the washer the present invention relates to can also comprise: to flow into the temperature of exhaust gas of cyclone inside and be connected to described cyclone inflow portion 21 and emission gases and flow into the saveall (economizer) 25 that plays the heat-exchange device that reduces gas temperature effect before cyclone body in order to reduce, groove (batch tank) 26 in batches can also be further set in addition, keep a certain amount of for the streamflow discharging from described cyclone body 20, and can be designed to, measure discharge running water level (head) therein, and under certain water level condition automatic-discharging.
In addition, the boats and ships that the present invention relates to comprise the steps: to flow into cyclone inflow portion 21 emission gases by the emission gases processing method of eddy flow washer is by the first step of the multiple seawater curtain film that formed by the first nozzle 22; The aitiogenic second step of seawater that flows into cyclone body 20 and discharge with second nozzle 23 by the emission gases of multiple seawater curtain film in described first step; And, with the aitiogenic emission gases of seawater of described second step by the third step of the multiple seawater curtain film that formed by second nozzle 23.
Described processing method also comprises: the emission gases by the multiple seawater curtain film that formed by second nozzle 23 after described third step finishes is by being formed at cylindrical portion upper end and for preventing the step of the mist separator (demistor) that acid mist (mist) reveals, making can further thoroughly remove by the acid mist in the emission gases of seawater curtain film.
Described processing method also comprises: emission gases, by playing the step of saveall (economizer) 25 of heat-exchange device effect, can be down to approximately 400 DEG C of above temperature of exhaust gas below 150 DEG C by described saveall before described first step.Emission gases by saveall is disposed to outside after by washer after seawater eroding drops to the state of cooling below 50 DEG C.
Now, after described third step completes, also can further comprise, the step of described saveall (economizer) 25 will be again transferred to from the emission gases of washer discharge, make emission gases again be circulated in heat-exchange device, so not only can reduce the temperature of inflow gas, and can obtain the state discharge of heating and then further increase with buoyancy to the gas of outside drain.
In addition, described second step can be designed to, discharge from described cyclone body 20 conus portions with the aitiogenic seawater of emission gases, flow into subsequently the discharge stream water yield is remained to a certain amount of batch groove (batch tank) 26, make to discharge flowing water automatic-discharging under certain water level condition.
Can be designed as by described processing method, the interior emission gases treatment process of boats and ships that does not need device expert and be not only convenient to operation but also can automatically control, does not need the other auxiliary equipments such as cooling device with timer inside, and maintenance management is convenient and simple.
The invention is not restricted to described specific embodiment and explanation; the personnel that possess general knowledge in this claim scope in the main idea of the present invention requiring in this technical field that the present invention belongs to all can carry out various distortion enforcement to it, and this class distortion case is all contained in protection scope of the present invention.
