In order to solve the above technical problems, seawater spiral desulfurizer of the present invention, including：Flue；Hollow shaft, the sky
Mandrel is connected to one end of the flue；Hollow impellers, the hollow impellers are described around the outside for being located at the hollow shaft
The inner cavity of hollow impellers is connected to the inner cavity of the hollow shaft；Gas vent, the gas vent are arranged in the hollow impellers.
Preferably, the gas vent is distributed in the hollow impellers backwards to the side of the flue.
Preferably, the gas vent is radially distributed using the hollow shaft as the center of circle.
Preferably, a diameter of 5 millimeters~100 millimeters of the gas vent.
Preferably, a diameter of 5 millimeters~30 millimeters of the gas vent.
Preferably, the percent opening of the gas vent is 20%~60%.
Preferably, booster fan is equipped on the flue.
Preferably, the hollow shaft by mechanical connection in one end of the flue.
Preferably, the mechanical seal includes：Stationary ring, the stationary ring set are connected to one end of the flue；Rotating ring,
The rotating ring is set on outside the stationary ring, the rotating ring and the hollow axis connection.
Preferably, ceramic seal face is equipped between the rotating ring and the stationary ring border.
Compared with prior art, seawater spiral desulfurizer of the present invention has following advantage：Using seawater alkalinity and
The high speed dispersion of hollow impellers carries out desulfurization to flue gas.Flue is connected by specific mechanical seal with hollow shaft
It connects, the water position that enters of hollow impellers is porous structure, and flue gas is ejected by the gas vent in hollow impellers, filled with seawater
Divide mixing, the sulfur dioxide in flue gas adequately to be mixed with the alkaline matter in seawater, realizes the purpose of desulfurization.

Specific implementation mode
With reference to specific embodiment, the present invention is described in detail.Following embodiment will be helpful to the technology of this field
Personnel further understand the present invention, but the invention is not limited in any way.It should be pointed out that the ordinary skill of this field
For personnel, without departing from the inventive concept of the premise, several changes and improvements can also be made.
The present invention is allowed to come into full contact with desulfurization, device with seawater using the high speed rotation of propeller for vessels to disperse flue gas
It is not take up hull limited bulk, does not also increase the additional weight of hull, unique power consumption is pressurizeed to flue gas, and cigarette is made
Gas blowout is incident upon sea level, makes flue gas directly and contact with sea water, using the alkalescent of seawater, makes the sulfur dioxide in flue gas and seawater
It directly reacts, desulfurization is carried out to the flue gas of foreign-going ship discharge.
As shown in FIG. 1 to 3, seawater spiral desulfurizer of the present invention, flue gas pass through pressurization in hollow flue 1
After wind turbine 2 is pressurized, into desulphurization system.The end of flue 1 and the hollow shaft 7 of propeller by 3 device of mechanical seal into
Row is connected.The stationary ring 5 of mechanical seal 3 is connected with 1 end of flue, when hollow shaft 7 runs at high speed, due to mechanical seal 3
Effect, flue 1 are in stationary state.Flue gas is transported to hollow impellers 4 by supercharging, is sprayed by the gas vent 8 above impeller
It shoots out, and running at high speed with hollow impellers 4, is come into full contact with seawater, since 4 rotating speed of hollow impellers reaches
Therefore 1000rpm or more, the sulfur dioxide in flue gas ejected can be adequately somebody's turn to do with the alkali substance reaction in seawater
Desulfurizer desulfuration efficiency is high.
Mechanical seal 3 is made of rotating ring 6 and stationary ring 5, and stationary ring 5 is connected with flue 1, and rotating ring 6 is connected with hollow shaft 7,
Centre is ceramic seal face 9.When 4 high speed rotation of hollow impellers, flue 1 is connected with stationary ring 5, the state of remains stationary,
The tightness in ceramic seal face 9 simultaneously, can prevent the escape of flue gas.
Hollow impellers 4 are single side trepanning, and opening direction is the back side of flue, ensure what the flue gas ejected advanced with ship
Direction is opposite.Since flue gas is by supercharging, there is certain kinetic energy, when flue gas is sprayed from the gas vent of impeller, the cigarette of ejection
Gas can promote the preceding action edge of ship.
The percent opening of a diameter of 50 millimeters of gas vent 8, osseotomy site is 30%.Desulfurization degree can reach 95% or more.For
Raising desulfurization effect can then be realized by increasing percent opening, and by reducing the diameter of gas vent 8.In this condition
Under, by a diameter of 10 millimeters of gas vent 8, the percent opening of osseotomy site is 50%.By improving percent opening and reducing flue gas row
The diameter of stomata 8 can make desulfurization degree reach 99% or more.
Device using the present invention, it is only necessary to existing propeller shaft and impeller are transformed, power plant is one
Booster fan does not need other power-equipments and desulfurizer, is not take up hull space.Since revolution speed of propeller is more than 1000
Rev/min, can high speed dispersion flue gas, so that seawater is sufficiently mixed with flue gas, realize the purpose of high-efficiency desulfurization.
Specific embodiments of the present invention are described above.It is to be appreciated that the invention is not limited in above-mentioned
Particular implementation, those skilled in the art can make a variety of changes or change within the scope of the claims, this not shadow
Ring the substantive content of the present invention.In the absence of conflict, the feature in embodiments herein and embodiment can arbitrary phase
Mutually combination.
