4. Chinese patent 200810048002, and title " desulfurizing exhaust gas of seagoing vessel method and device " is used the material filling type washer that the flue gas of seagoing vessel engine is carried out desulfurization and handled, and it is big to have a washer diameter, and equipment occupation space is big, problems such as cost height.
5. marine diesel giant
The alkali liquid washing technology of company, volume is big, and equipment is many, and is newly-built all very high with improvement cost.
In the above-mentioned prior art, the use that has the method for seawer washing, boats and ships are endless to be provided though seawater can be, and in order to raise the efficiency, needs high flowing seawater that enough basicity is provided, the seawater consumption is very big.
Above prior art also faces following common problem:
(1) in the present circumstance, its cost of environmental requirement that satisfy the discharging of fume emission and seawater is difficult to accept; If drainage condition further improves, its cost will continue to increase.
(2) device takes up room greatly, to the transformation difficulty of spot ship.
(3) can not satisfy boats and ships in variant sea area, every environmental condition of different pollutants control zone.
Summary of the invention
In order to solve the problem that above-mentioned prior art exists, the purpose of this utility model provides a kind of device to boats and ships smoke evacuation carrying out alkali desulphurization.It can satisfy very high desulfuration efficiency under the smaller situation of water consumption, have the advantages that space hold is little, cost is low, is applicable to boats and ships or oil burning boiler desulfurization that the navigation of different sea areas and pollutant control interval is moved.
In order to reach the foregoing invention purpose, the technical solution of the utility model realizes as follows:
A kind of device to boats and ships smoke evacuation carrying out alkali desulphurization, it comprises the engine/oil burning boiler on the boats and ships.Its design feature is, the exhaust of described engine/oil burning boiler is connected to scrubbing tower through flue, is provided with the spraying layer that is connected with the alkali lye service in the washing Tata, and fresh water supply unit is connected to the bottom of scrubbing tower by pipeline.The wash tower bottoms outlet is connected to the alkali lye service through baffle-box, pump and heat exchanger successively, and the outlet of heat exchanger also links to each other with the inlet of separator, and two outlets of separator connect discharge tube and sludge tank respectively.Alkali lye supply unit is connected with the alkali lye service.
In the device of above-mentioned alkali desulphurization, described spray thrower adopts one-level or multi-stage spray layer.
