Description
Technical field
The utility model relates to a kind of Protection for Optical Instruments device, belongs to Technology of Precision Measurement field, particularly a kind of optical element protective device being suitable for open type Fourier turn infrared monitoring system.
Background technology
The source of atmospheric pollution is of a great variety, and the waste gas of chemical industry plant emissions is as one of the chief component of the source of atmospheric pollution, and waste gas mainly comprises volatile organic matter (VOSs), toxic gas (HAPs), organic solvent and acid-base material.Along with Domestic Environment problem is more and more outstanding, the environmental consciousness of the public day by day improves, and the degree of concern of atmospheric pollution is more and more higher.But the concentration of plant emissions waste gas is lower, kind is more, scope is comparatively wide, very easily by meteorologic factor, as wind direction, air speed influence.How accurately, in time, effectively, reliably air pollution monitoring source concentration, be very urgent difficult problems.Traditional sampling analysis system can not be suitable for the on-line monitoring of the source of atmospheric pollution of Small and Medium Sized scale, is difficult to, according to setting threshold value real-time early warning, more be difficult to review the source of atmospheric pollution in conjunction with meteorologic factor.Traditional sampling analysis system has some defects, mainly: measurement range is narrow, monitoring velocity is slow, monitoring kind is few, limit of detection is high, is difficult to be suitable for real-time, wide spectrum, sensitive source of atmospheric pollution monitoring requirements.
Open type Fourier turn infrared monitoring system (OP-FTIR) is compared to traditional sampling analysis system, there is the advantages such as measurement range is wide, detection speed fast, monitoring kind is many, limit of detection is low, be suitable for the on-line monitoring for volatile organic matter, toxic gas, organic solvent and acid-base material.Open type Fourier turn infrared monitoring system comprises a FTIR main frame, a collimating optics telescope, a corner-cube reflectors array and a spectral analysis software and main frame, as shown in Figure 6.Described open type Fourier turn infrared monitoring system utilizes described collimating optics telescope parallel injection modulated infrared light bundle, modulated infrared light bundle is through open surrounding air, and described corner-cube reflectors array reflection modulation infrared beam is to described collimating optics telescope.Because different types of atmosphere pollution absorbs the infrared light of different wave length, described spectral analysis module resolves the infrared absorption spectrum of the modulated infrared light bundle be reflected back, and gets final product the mean concentration of on-line monitoring light path atmosphere pollution along the line.Described FTIR main frame comprises an interferometer further, dynamically straight accurate described interferometer autocollimation can calibrate light path, avoid vibration and the described open type Fourier turn infrared monitoring system of atmospheric temperature change interference, guarantee that described open type Fourier turn infrared monitoring system is normally run in rugged surroundings.
Described collimating optics telescope and described corner-cube reflectors array are the important optical elements of described open type Fourier turn infrared monitoring system.And if only if just can guarantee that the modulated infrared light bundle that described optical element is launched accurately is back to described optical element after the light path of about 1000 meters under described optical element do not have contaminated and uncorroded situation, the receiving intensity being simultaneously back to the modulated infrared light bundle of described optical element meets examination criteria, guarantees that described open type Fourier turn infrared monitoring system is precisely run in rugged surroundings.
General, described open type Fourier turn infrared monitoring system is applicable to being installed on Small and Medium Sized scale region, as chemical industry factory.Because in chemical industry factory, factory building is in a compact mass, in length and breadth, personnel, vehicle come and go frequent, in order to ensure that light path intermittently or is not permanently stopped by personnel, vehicle and other barriers road, usually described corner-cube reflectors array is installed on eminence, as places such as clump, chemical industry truss.Described corner-cube reflectors array is open air facilities, does not have corresponding protective device.In addition, described open type Fourier turn infrared monitoring system monitors many light paths usually simultaneously, described open type Fourier turn infrared monitoring system comprises multiple described corner-cube reflectors array, described in described FTIR host computer control, collimating optics telescope scans described corner-cube reflectors array successively, and the mean concentration of the atmosphere pollution of many light paths monitored by described FTIR main frame simultaneously.
It is worth mentioning that, the outdoor installation of described corner-cube reflectors array, is in chemical industry plant area or in the rugged surroundings of periphery.In order to ensure precision and the intensity of modulated infrared light bundle, the translucent covers such as optical glass can not be installed in the dead ahead of described corner-cube reflectors array, cause described corner-cube reflectors array to be directly exposed to for a long time in rugged surroundings.Therefore, there is some defects in traditional described open type Fourier turn infrared monitoring system, mainly: described optical element is directly exposed in rugged surroundings for a long time, the surface very easily adhesive dust of described optical element, the acidic materials carried in dust are attached to the surface of described optical element, accumulate over a long period and just can corrode described optical element; Described optical element is directly exposed in rugged surroundings for a long time, and when ambient humidity is higher, acid droplet directly sticks to the surface of described optical element, further the described optical element of corrosion; Described optical element is directly exposed in rugged surroundings for a long time, when the temperature of the surroundings is low, the surface very easily frosting of described optical element, be attached to the light path that the frost and dew on the surface of described optical element and dust very easily disturb modulated infrared light bundle, cause described optical element accurately can not receive the modulated infrared light bundle be reflected back, greatly affect accuracy of detection, even cause described open type Fourier turn infrared monitoring system monitors failure; Described optical element is directly exposed in rugged surroundings for a long time, and the biology such as insect is usually subject to the monitoring range that described optical element attracts or is strayed into described open type Fourier turn infrared monitoring system, causes monitoring result abnormal, causes erroneous judgement.In addition, because described corner-cube reflectors array comprises multiple prism, usually install 30 to 60 described prisms, described prism has three minute surfaces, and the installation site of described optical element is higher in addition, is unsuitable for cleaning described optical element completely.On the other hand, described prism adopts craft of gilding, and deviation is less than 10 rads, and the described number of prisms of described optical element needs is numerous in addition, and be unsuitable for integral replacing or partly change described optical element, the cost of routine maintenance is higher.
