Technical field
The invention belongs to environmentally friendly exhaust-gas treatment fields, more particularly to dioxy caused by the operation carriers such as ship and power plant
Change sulphur exhaust gas and carries out purified treatment.
Background technique
Marine fuel and coal etc. after combustion, can be generated containing oxysulfide (hereinafter SOX), nitrogen oxides (after
Literary abbreviation NOX) etc. substances, these substances can be discharged into atmosphere in the form of exhaust gas.And SOXIn SO2, in an atmosphere can shape
At acid rain, harm is generated to environment and the mankind.It administers sulfur dioxide and has become global common recognition, International Maritime Organization (IMO)
" 73/78 anti-pollution convention " (MARPOL pact) supplemental provisions VI requirement: i.e. from 2012, in the combustion for the foreign-going ship that high sea are exercised
Oily sulfur content has to be lower than 3.5%(m/m), would fall to 0.5%(m/m to the year two thousand twenty), and this scheme is completed feasibility and is examined
It will be carried out earlier than 2018.
Existing flue gas desulfunzation device is sprayed into lye in exhaust gas in spraying form using spray wet desulphurization, with
Exhaust gas mixing, is chemically reacted SO in exhaust gasX、NOXIt captures and enters in liquid phase, achieve the purpose that purification.But exhaust gas is generally high
Temperature, lye spray into meeting partial gasification in exhaust gas, are discharged together with exhaust gas, it is possible to cause secondary pollution.And spray process can generate
A large amount of waste water needs to increase complicated waste water treatment system, increases energy containing a large amount of flue dust, oil, heavy metal etc. in waste water
Consumption increases cost, and bulky spray tower systems are not advantageously mounted on production platform.
In currently used equipment, liquid in-out mouth only one, liquid is not completely filled in many ceramic-film tubes or is not had
There is liquid, cause desulfuration efficiency low, and the waste to ceramic-film tube.Secondly it is influenced, is filled by temperature in practical applications
Deformation can be generated by setting, and lead to ceramic tube fracture or ceramic tube and the failure of outer loop piping connection.Or during transportation
Jolting or shaking leads to failure of apparatus.In addition, ceramic membrane used by the device is impermeable layer, membrane aperture size is on the left side 10nm
