Seawer washing, the second scrubbing section are alkali liquid washing, to reduce alkali lye consumption.
The course of work of the ship tail gas wash mill is as follows:
(1) coolant circulation system is coolant liquid to evaporation cooling zone feed flow using seawater or lye, and ship tail gas is from ship
Vessel exhaust air inlet enters evaporation cooling zone and caloic exchange is contacted and carried out with coolant liquid, and coolant liquid absorbs the heat of ship tail gas
After evaporate, promote that the temperature of ship tail gas reduces, humidity increases and approach adiabatic saturation state;
(2) ship tail gas close to adiabatic saturation state of evaporation cooling zone is left by the first demister and by first
Ventilation liquid-preventing device enters the first scrubbing section and either the first alkali liquor circulating system or shared lye follow by cleaning solution open system
The cold washing liquid of loop system supply contacts, and the acidic materials in ship tail gas based on oxysulfide are washed liquid and absorb, and
And since cleaning solution temperature is low, the temperature difference is big between ship tail gas, therefore ship tail gas forms satiety during gas-liquid contact
And moisture state, and then promote a large amount of vapour molecules in ship tail gas solidifying by nucleation centre phase transformation of the surface of the particle in tail gas
Knot promotes cleaning solution by particle capture along with the effect of diffusiophoresis and thermophoresis makes particle collision reunite and then the thickening that increases weight

In the present embodiment, alkali liquor circulating system is shared can be also discharged to evaporation cooling zone 2 by sharing overflow passage 93
Extra cleaning solution.
In conjunction with the embodiments one, the operation principle of the ship tail gas wash mill is made described further below:
(1) coolant circulation system is coolant liquid to evaporation 2 feed flow of cooling zone using seawater or lye, and ship tail gas is from ship
Vessel exhaust air inlet A enters the coolant liquid that evaporation cooling zone 2 is sprayed with coolant nozzle 23 through cooling zone ventilation liquid-preventing device 26 and connects
Caloic exchange is touched and carried out, is evaporated after the heat of coolant liquid absorption ship tail gas, promotes the temperature of ship tail gas to reduce, humidity increases
The close adiabatic saturation state of adduction;Coolant liquid is sprayed under the action of coolant recirculation pump 25 in cooling zone liquid storage tank 21, coolant liquid
It is recycled between mouth 23, void tower area 22, in the process, there are two types of modes to leave evaporation cooling zone 2 for coolant liquid, first, passing through evaporation
The condensation of the first scrubbing section 3 is taken in the form of water vapor, second is that the cooling concentrated by evaporation is discharged from coolant liquid overflow pipe 294
Liquid, also there are two types of modes supplements coolant liquid to evaporation cooling zone 2, first, add fresh coolant liquid from cooling liquid inlet 292, two
It is, when the first alkali liquor circulating system is the first 3 feed flow of scrubbing section, the extra cleaning solution of also the first alkali liquor circulating system discharge
Evaporation cooling zone 2 is flowed into from the first overflow passage 72, by adjusting the liquid measure for the fresh coolant liquid that cooling liquid inlet 292 is added,
The coolant liquid stable components for making cooling zone liquid storage tank 21 ensure that the liquid level of cooling zone liquid storage tank 21 is steady by coolant liquid overflow pipe 294
It is fixed.
(2) ship tail gas close to adiabatic saturation state for leaving evaporation cooling zone 2 removes defogging by the first demister 24
The first scrubbing section 3 is entered by the first ventilation liquid-preventing device 5 after drop, and by cleaning solution open system or the first alkali liquor circulating system
Or the cold washing liquid of shared alkali liquor circulating system supply contacts, the acidic materials quilt in ship tail gas based on oxysulfide
Cleaning solution absorbs, and since cleaning solution temperature is low, the temperature difference is big between ship tail gas, and ship tail gas is during gas-liquid contact
Supersaturated vapor state is formed, and then promotes in ship tail gas a large amount of vapour molecules using the surface of the particle in tail gas as in coring
Heart phase transformation condenses, and along with the effect of diffusiophoresis and thermophoresis makes particle collision reunite and then the thickening that increases weight, promotes cleaning solution will
Particle capture simultaneously efficiently removes.
(3) ship tail gas after the washing of the first scrubbing section 3 enters the second scrubbing section 4 by the second ventilation liquid-preventing device 6
Washed liquid further washs, and by cleaning solution open system, either the second alkali liquor circulating system or shared lye recycle cleaning solution
System supplies;
Wherein, when allowing outer row's cleaning solution, according to seawater situation, sulphur content of fuel oil situation and emission request, divide three kinds
Situation:
1) the first alkali liquor circulating system closes, the second alkali liquor circulating system closes, the cleaning solution open system of the second scrubbing section 4

Valve 106 closes, and the 8th valve 108 closes, and solution feed pump 12 is opened, and the 7th valve 107 is opened, the 9th valve 109 is opened, cleaning solution open system
It is cleaning solution to 3 feed flow of the first scrubbing section using seawater, the comb outside waste liquid of the waste seawater after washing is discharged.The program be suitable for through
After the seawer washing of first scrubbing section 3, the case where exhaust emissions requirement can be reached.
2) the first alkali liquor circulating system closes, the second alkali liquor circulating system closes, the cleaning solution open system of the first scrubbing section 3
