Description
Technical field
The invention belongs to Industrial Boiler Technology field, SO 2 from fume concentration determination takes under particularly a kind of cold environment
Sample system.
Background technology
The sampling analysis of fired power generating unit exhaust gas components is to monitor one of important test event of unit pollutant emission, wherein
The concentration determination of contained sulfur dioxide is main test event again in flue gas.But sulfur dioxide is dissolved in water in itself, especially in cold
Sampled under environment, the moisture often occurred in the gas that gathers condense in sampling pipe, causes under test gas soluble in water, generation
Measurement error.Meanwhile, under cold conditions, flue gas sampling device will often be preheated and for a long time could normally used, when causing measurement
Between extend.
The content of the invention
The purpose of the present invention is in view of the shortcomings of the prior art, and to propose SO 2 from fume concentration under a kind of cold environment
Test sampling system.
The present invention solves its technical problem and takes following technical scheme to realize：
SO 2 from fume concentration determination sampling system under a kind of cold environment, including flue gas analyzer, heating sampling gun
And heating sampling flexible pipe, installed additional in the outside of flue gas analyzer in flue gas analyzer heater box, the flue gas analyzer heater box
Portion by by-level dividing plate be divided into above and below two spaces, top be smoke pre-heating space, bottom be flue gas analyzer accommodation space,
Resistive heater is installed in the bottom of flue gas analyzer heater box, the heating sampling gun by heat after sampling flexible pipe with cigarette
The top flue gas preheating space connection of qi leel analyzer heater box, smoke pre-heating space is connected by connecting smoke pipe with flue gas analyzer
Connect, the flue gas after preheating is conveyed to flue gas analyzer.
Moreover, the flue gas analyzer heater box bottom is further fitted with temperature control module, temperature control module control heating electricity
The break-make of silk is hindered, when smoke pre-heating space temperature is less than setting lower limit, resistive heater electrified regulation, when smoke pre-heating space temperature
Degree stops heating higher than the setting upper limit, resistive heater power-off.
Moreover, the flue gas analyzer heater box is made up of double-deck zinc-plated tinplate, filled out between double-deck zinc-plated tinplate
Filled with heat-insulation layer.
Moreover, the heating sampling flexible pipe uses the structure of metal hose outsourcing thermal insulation layer.
Advantages and positive effects of the present invention are：
Present invention reduces instrument sample time, it is possible to prevents moisture condensation in gas, enhancing sulfur dioxide test essence
Degree.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Embodiment
The embodiment of the present invention is further described below in conjunction with accompanying drawing：It is emphasized that of the present invention implement
Example is illustrative, rather than limited, therefore the present invention is not limited to the embodiment described in embodiment, every
The other embodiment drawn by those skilled in the art's technique according to the invention scheme, also belongs to the model that the present invention is protected
Enclose.
SO 2 from fume concentration determination sampling system under a kind of cold environment, as shown in figure 1, including flue gas analyzer 2,
Sampling gun 6 and heating sampling flexible pipe 5 are heated, innovative point of the invention is to install flue gas analyzer additional in the outside of flue gas analyzer
Inside heater box 4, the flue gas analyzer heater box by central dividing plate be divided into above and below two spaces, top be smoke pre-heating space
3, bottom is flue gas analyzer accommodation space, and resistive heater, adding thermal resistance are provided with the bottom of flue gas analyzer heater box
Silk is the heating of whole flue gas analyzer heater box, and the heating sampling gun after heating sampling flexible pipe with flue gas analyzer by heating
The top flue gas preheating space connection of case, sampling flue gas is pre-processed, smoke pre-heating space is by connecting smoke pipe and flue gas
Analyzer is connected just, and the flue gas after preheating is conveyed into flue gas analyzer.Moisture condensation in gas is prevented and band by heating
The measuring accuracy come declines.
In the specific implementation of the present invention, the flue gas analyzer heater box bottom is further fitted with temperature control module, temperature
The break-make that module controls resistive heater is controlled, lower limit is set when smoke pre-heating space temperature is less than, resistive heater electrified regulation,
When smoke pre-heating space temperature is higher than the setting upper limit, resistive heater power-off stops heating.
In the specific implementation of the present invention, the flue gas analyzer heater box is made up of double-deck zinc-plated tinplate, in bilayer
Heat-insulation layer is filled between zinc-plated tinplate.
In the specific implementation of the present invention, because heating sampling flexible pipe is exposed to exterior space, moisture condensation is easily produced
Phenomenon, therefore, the heating sampling flexible pipe use the structure of metal hose outsourcing thermal insulation layer.Inner metal hose is easy to receive cigarette
The heat that gas preheating space is passed over, keeps high temperature, and outsourcing thermal insulation layer prevents heat scatters and disappears from causing moisture condensation phenomenon.
