Description
Technical field
The utility model relates to a kind of smoke dust sampling device, particularly a kind of Visual Sampling device of air flue soot dust granule.
Background technology
Along with the mankind's going deep into the understanding of smoke contamination harmfulness, people have higher requirement to the concentration of the flue dust of each discharge of pollutant sources and particle diameter, and national governments are also corresponding has formulated various emission standard and regulation.The control of gross contamination emission is a complicated systems engineering, and determines that the discharge capacity of pollutant is the basis of overall control.The measurement of the discharge capacity of pollutant needs certain detection means, testing result be weigh each pollution unit discharge the most directly, the most convictive voucher.For flue dust controls, record the total emissions level that smoke dust discharge concentration can calculate emission source within a certain period of time further.Therefore, development on-line continuous measures the instrument of soot dust granule thing particle diameter and concentration, has very important meaning to control atmospheric pollution.
The sampling of air flue soot dust granule is the primary part realizing soot emissions on-line real-time measuremen.Therefore, for the remote online monitoring device of air flue soot dust adopting computer vision technique, can the clear image information obtaining flue in high quality be the key of device success or failure.
Flue is an airtight environment, its inwall adhesion person soot dust granule.If adopt usual means pickup image, because flue inner wall as a setting has same color with the soot dust granule flowed in flue, therefore obtain just without any the monochrome image of content, cannot therefrom differentiate or identify soot dust granule.
Summary of the invention
The utility model is the problem for air flue soot dust granule sampling difficulty, propose a kind of Visual Sampling device of air flue soot dust granule, adopt a kind of Smart industrial camera, clearly can obtain the image information of flue by high-quality, appropriate design sampling apparatus, equivalently reflects chimney and is finally discharged into the soot dust granule situation in air.
The technical solution of the utility model is: a kind of Visual Sampling device of air flue soot dust granule, homonymy upper and lower Ge Kai mono-window of flue, lighting source is positioned at window, light source exports directional light incident flue obliquely, a heat insulation air curtain curtain installed by lower window, imageing sensor is positioned at outside lower window, soot dust granule image is gathered by heat insulation air curtain curtain, the optical axis of lighting source and the horizontal pickup axis of imageing sensor intersect at the centre position of flue, and the information of the soot dust granule image that imageing sensor collects is converted to numerical data and sends into industrial computer.
Described lighting source adopts caesium lamp.
Described heat insulation air curtain curtain adopts heat-resisting high printing opacity quartz glass.
The beneficial effects of the utility model are: the Visual Sampling device of the utility model air flue soot dust granule, not only can realize the vision collecting of air flue soot dust granule, but also can realize long distance online real-time monitor.Solving a difficult problem for emission measurement difficulty, providing strong foundation for controlling atmospheric pollution.
Accompanying drawing explanation
Fig. 1 is the Visual Sampling apparatus structure schematic diagram of the utility model air flue soot dust granule.
Embodiment
The Visual Sampling apparatus structure schematic diagram of the utility model air flue soot dust granule as shown in Figure 1, flue 8 is dark seals, and therefore gathering image must, by certain light source 1, adopt caesium lamp to produce uniform directional light herein.Smart image sensors 2 and lighting source 1 are arranged on the lateral opening place of fume emission passage 8.Flue is herein a part for fume emission passage (boiler-> electrostatic precipitator-> flue-> chimney), and it equivalently reflects chimney and is finally discharged into soot dust granule 4 situation in air.For ensureing the ambient temperature conditions that smart image sensors 2 can normally work, at the lateral opening of the fume emission passage of smart image sensors 2 correspondence, one heat insulation air curtain curtain 3 is installed, heat insulation air curtain curtain 3 adopts heat-resisting high printing opacity quartz glass to completely cut off the high temperature of flue inside, air curtain curtain technology can prevent and remove window surface and adhere to soot dust granule, otherwise the laying dust that window surface produces can make smart image sensors can not the clear image that even cannot obtain flue inside.When smart image sensors 2 and lighting source 1 are installed, the optical axis 5 of lighting source and the horizontal pickup axis 7 of smart image sensors 2 is made to intersect at the centre position of flue 8, as sample region in figure 6, the angle of the position that light source 1 is installed and inclined light shaft ensures that the focusing surface of smart image sensors 2 has enough illumination, but do not illuminate the background of imaging, clearly can obtain the flue dust picture information in the middle of flue 8 like this.If install and can not meet requirement like this, so soot dust granule is difficult to identification in homochromy background.Smart image sensors 2 the information of the soot dust granule image collected is converted to digital form after send into industrial computer 9, data store and show by industrial computer 9, can also be realized the monitoring of soot dust granule situation by certain arranging, industrial computer application software drives loudspeaker 10 to reach the function of control survey warning.
Industrial computer 9 is processed data by software, shows, and free defined parameters and setup parameter value generate chart, and setting ultimate value is reported to the police, and formed and can monitor dust concentration at any time and the monitoring device of reporting to the police, concrete monitoring of software operation steps of illustrating is as follows:
1, set emission measurement program and run initial time;
2, set the smoke granularity limit to arrange, i.e. alarm parameters setting;
3, the reduced parameter limit is arranged, and draws correlation curve;
4, light source normal/abnormal instruction is green when light source is normal, become redness if abnormal, represent light source may go bad or light-source brightness decay excessive, need more to change the bulb;
5, particle diameter (X-axis)-granule number (Y-axis) histogram display;
6, data and curves display, time m-granularity (%) figure, transverse axis corresponding data writing time, the corresponding smoke granularity of the longitudinal axis;
7, alarm speaker switch opens, smoke granularity is greater than setting value, will send chimes of doom;
8, automatic printing alert data functional switch is opened, the time span value of setting automatic printing alert data, namely sends moment of reporting to the police forward and backward time span value; When smoke granularity is greater than setting value, according to the time value automatic printing data and curves of setting, display exceeds standard value and time.
Above setting operation can set according to concrete needs are selected, to realize the function of on-line real time monitoring and warning.
