Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
A kind of ship tail gas scrubbing tower shown in Fig. 1~2 includes tower body 4, it further includes swirl-flow devices 15, two-fluid spray nozzle
5th, heat exchanger 12；The lower part of tower body 4 is symmetrically opened up there are two tangentially-arranged flue gas secondary inlet 1；Under flue gas secondary inlet 1
End offers overflow port 2, washing water outlet 3 successively；Washing water outlet 3 is used to discharge the flue dust after washings and condensation
Particle, overflow port 2 close nozzle as spare aerial drainage, prevent the liquid level caused by washing water outlet 3 blocks or discharge capacity is excessive
Raising.
The top of flue gas secondary inlet 1 is provided with swirl-flow devices 15, and the top of swirl-flow devices 15 is provided with dust collect plant 14；
Swirl-flow devices 15, dust collect plant 14 may be contained within the inside of tower body 4, symmetrically enter inside tower body 4 from two flue gas secondary inlets
Two strands of flue gases swirling eddy is formed by the effect of blocking of swirl-flow devices 15 first, then pass through on dust collect plant 14 continues
Row；
The top of dust collect plant 14 is provided with two-fluid spray nozzle 5；Two-fluid spray nozzle 5 has been sequentially arranged above first order jet nozzle
6th, secondary nozzle 7；While flue gas forms swirling eddy by swirl-flow devices 15, two-fluid spray nozzle 5, first order jet nozzle 6, two level spray
Mouth 7 carries out counter flow washing spray against swirling eddy simultaneously；First order jet nozzle 6, secondary nozzle 7 are all less than 5mm for spraying diameter
Cleaning solution particle, and two-fluid spray nozzle 5 can be used for sprinkling diameter be less than 1mm cleaning solution particle；First order jet nozzle 6, two level spray
Mouth 7,5 comprehensive function of two-fluid spray nozzle can not only realize best flue dust absorption, diffusion effect, but also absorption area bigger, work
With uniform, the usage amount of washings can be reduced to greatest extent.
Flue dust after spray in swirling eddy to form larger micro- mist particle through making moist, adsorbing, and micro- mist particle is revolved at a high speed
The effect of the airflow centrifugal power turned is drop in dust collect plant 14, is discharged eventually by washing water outlet 3 with washings；
During spray, the alkaline matter in sulfur dioxide and washings in swirling eddy chemically reacts, so as to fulfill desulfurization
Purpose；The ingredient of washings can select the mixture of the seawater easily obtained or seawater and sodium hydroxide solution.
The top of secondary nozzle 7 is provided with demister 11, and demister 11 is further right during swirling eddy rises
Mist plays absorption, sedimentation, and the moisture in swirling eddy is completely eliminated；The upper end of demister 11 is provided with heat exchanger
12, flue gas level-one entrance 8, flue gas primary outlet 9 are offered respectively on the tower body 4 in the outside of heat exchanger 12；
Flue gas level-one entrance 8, flue gas primary outlet 9 are correspondingly arranged on two opposite sides of heat exchanger 12, contain height
The former flue gas of heat by heat exchanger 12 when, can with rising and come swirling eddy occur heat exchange, to relatively dry
Swirling eddy is heated, and enters higher height in the air after making it through the discharge of flue gas secondary exit port 10 of 4 upper end of tower body, so as to
In higher position regelation into water droplet, water droplet is made to descend slowly and lightly farther, far from ship tail portion deck area.
Flue gas primary outlet 9 is connected by bifurcated passage with two flue gas secondary inlets respectively；Former cigarette after heat exchange
Gas enters tower body 4 by bifurcated passage and flue gas secondary inlet, realizes the carrying out washing treatment of ship tail gas.
Monitor 13 is provided at the flue gas secondary exit port 10 of tower body 4, for detecting the sulfur content of emission；If sulphur contains
Measure up to standard, then normal discharge；If sulfur content is not up to standard, increases spray flux or improve the concentration of shower water neutral and alkali substance, directly
It is qualified to detection.
The utility model has the advantage that compared with traditional technology：
1) fume recovery is efficient, and washings water consumption is few, and the washings after spray process are smaller with respect to turbidity, reachable
To IMO discharge standard direct emissions, the feature of environmental protection is stronger；
2) desulfurization effect is good, and the flue gas emission after washing to air is not likely to produce misty rain；
3) discharge flue gas is heated using the heat of former flue gas, discharge flue gas is made to rise to higher high-altitude, is descended slowly and lightly
It is farther, so as to avoid making dirty or corrode ship deck.
The above embodiment is not the limitation to the utility model, and the utility model is also not limited to the example above,
