Description
Technical field
This utility model belongs to ship flue gas monitoring equipment art field, and in particular to supervise to a kind of for ship flue gas
Survey the ship smoke ultraviolet differential gas analyzing apparatus of analysis.
Background technology
Marine exhaust exhaust emission is to constitute one of atmospheric pollution and marine environmental pollution primary pollution source, most of ships
The Fossil fuel of burning is typically on market containing the higher fuel of pollutant, the carbon dioxide of post combustion emission, nitrogen oxides and
Oxysulfide can directly affect global climate and marine environment acidifying, and other liquid of release, gas and granule are good for the mankind
Health also constitutes serious threat.
Flue gas is needed through ultraviolet difference method in flue gas after pretreatment removes moisture therein and other impurity
SO2、NO、NO2Analyze etc. the concentration real-time detection of multiple gases.
Utility model content
The purpose of this utility model is to seek to design a kind of ship flue gas that can be applied to ship flue gas monitoring system
Ultraviolet difference gas analyzing apparatus, it is adaptable to the use of marine environment, improves certainty of measurement.
To achieve these goals, the technical solution adopted in the utility model is：
A kind of ship smoke ultraviolet differential gas analyzing apparatus, including xenon flash lamp, condenser lenss, integrator, fiber optic cables,
Gas flow cell, gas flowmeter, collimator and spectroanalysis instrument, the xenon flash lamp are located at the focal point of condenser lenss side,
Integrator is located at the focal point of condenser lenss opposite side；Light entrance of the integrator by fiber optic cables with gas flow cell connects
Connect, the flow cell is provided with smoke inlet near one end of light entrance, flow cell is provided with exhanst gas outlet near one end of light exit,
The smoke inlet is connected with effusion meter by pipeline, and effusion meter is connected with air pump by pipeline, can realize at the uniform velocity constant
Flue gas to be measured is passed through into flow cell；Collimator is provided with the light-emitting window of the flow cell, collimator passes through fiber optic cables and light
Spectrometer connects.
Preferably, the exhanst gas outlet is connected with waste gas recovering device by pipeline, and pipeline is provided with check valve.
Xenon flash lamp is converged as the light that light source sends and enters optical fiber, by fiber-optic transfer to measuring chamber, when flue gas to be measured
During by flow cell, different gases will absorb wave energy in different specific bands, and the light beam after being absorbed is passed by optical fiber
It is defeated to spectrogrph, through detection and analysis inside spectrogrph, finally give the concentration of under test gas species in flue gas.
The beneficial effects of the utility model are：
The multiple gases in flue gas to be measured, including SO can disposably be tested and analyzed2、NO、NO2, CO etc., efficiency high；Detection
