Abstract
The utility model discloses a fume on-line monitoring instrument measuring probe, the front shooting window mirror 1 and the corner reflection mirror 9 are respectively provided with a mutually independent air blowing device, and are respectively arranged on the both sides of the flue 6; The two air blowing devices are connected by a dead lever 8; the back end of the air blowing device where the corner reflection mirror is positioned is provided with an end cover 11. Owing to the fact that the corner reflection mirror of the probe is positioned outside the flute and free from the corrosion by the moist heat fume inside the flue, the utility model is extendable in service life and convenient to be maintained; the corner reflection mirror surface can be cleaned only by unclosing the end cover of the air blowing device provided with a corner reflection mirror to take out the corner reflection mirror.
Description
Technical field
The utility model relates to a kind of on-line monitoring instrument that pollutant in the flue is carried out online detection with the high-resolution spectroscopy technology.
Background technology
The difference of monitoring according to the method for sampling for continuous blow-down smoke is divided into three kinds usually: dilution sampling method, directly bleed sampling method and spot sampling method.Wherein, the spot sampling method is detecting element promptly to be popped one's head in directly be positioned in the flue, and the light that is injected in the flue is reflected back, and obtains the concentration that flue gas has pollutant by the inverting of optics difference absorption spectrum technology.The disclosed a kind of on-line continuous monitor that comes to this of Chinese patent CN2513103Y; the advantage of this monitor is that air purge set is set; with the pressure gas of cleaning to be exposed in the flue come and go outgoing front window mirror that light path links with light and the corner reflector minute surface on the probe purges protection; avoided the interior flue dust of flue to enter the light source exit end and pollute corner reflector, can guarantee the monitor operate as normal and prolong maintenance period.Its shortcoming is that the critical piece corner reflector of probe is positioned at flue, is vulnerable to the corrosion of damp and hot flue gas, when probe is safeguarded, the probe taking-up just can must be taken off eyeglass and clean, because probe diameter is bigger, needs multi agent cooperation, operation inconvenience.
Summary of the invention
In order to solve the problem that above-mentioned smoke gas on-line monitor probe is perishable and maintenance is inconvenient, the utility model provides a kind of smoke gas on-line monitor measuring sonde, not only can prolong the serviceable life of popping one's head in, and attended operation is convenient.
The utility model is to solve like this: comprise corner reflector and to coming and going the air purge set that the minute surface of outgoing front window mirror that light path links, corner reflector is protected with light; it is characterized in that described outgoing front window mirror, corner reflector are respectively equipped with separate air purge set; and be separately positioned on the both sides of flue, be connected by fixed bar between two air purge sets.Because the corner reflector of probe is located at outside the flue, be not subjected to the corrosion of the damp and hot flue gas in the flue, can prolong serviceable life, and easy to maintenance.
Safeguard that for convenience the air purge set rear end at corner reflector place is provided with the end cap that makes things convenient for corner reflector to take out.
The beneficial effects of the utility model are embodied in: 1, corner reflector is located at the flue outside, is not subjected to the corrosion of the damp and hot flue gas in the flue, can increase the service life; 2, easy to maintenance, only need the air purge set end cap of opening installation corner reflector can take out corner reflector, cleaning corner reflector minute surface; 3, do not establish the air channel in the fixed bar of connection probe, thereby diameter is little, is difficult for laying dust, can not influence light path because of its laying dust; 4, establish independently air purge set diagonal angle mirror mirror and protect, blast is not suffered a loss, and the air quantity foot is protected effective.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 be among Fig. 1 A to structural representation.
Among the above-mentioned figure, 1, outgoing front window mirror, 2, outer tube, 3, interior pipe, 4, air intake opening, 5, gas channel, 6, flue, 7, the gas outlet, 8, fixed bar, 9, corner reflector, 10, spring, 11, end cap.
Embodiment
As shown in Figure 1; to outgoing front window mirror 1; the air purge set that corner reflector 9 is protected is separately positioned on the left and right sides of flue 6; by outer tube 2; interior pipe 3; air intake opening 4; gas channel 5 (being the dotted portion of band arrow among Fig. 1) and gas outlet 7 are formed; corner reflector 9 is contained in by spring 10 in the interior pipe 3 of air purge set on right side; the rear end of this air purge set is provided with end cap 11; serve as reasons incident light through outgoing front window mirror of pipe 3 centers is represented light of hollow arrow among Fig. 1 and the catoptrical path channels of returning through corner reflector 9 in the air purge set of the left and right sides; about be connected by two fixed bars 8 between two air purge sets, can save the straight required time of light path when installing.Purge gas is entered by the air intake opening 4 of left and right sides air purge dress respectively; and by the gas channel 5 between outer tube 2 and the interior pipe 3 through the gas outlet 7 and flow out; 7 places, gas outlet form gas curtain with prevent flue gas flue 6 in enter in pipe 3, thereby protect pop one's head in the outgoing front window mirror 1 at two ends and the eyeglass of corner reflector 9 not polluted rapidly by dirty wet flue gas.When needs cleanings corner reflector 9, only need outside flue, turn on the thread ending cover 11 of probe front end and can take out spring 10 easily and corner reflector 9 cleans.Because the critical piece outgoing front window mirror 1 and the corner reflector 9 of probe all are in outside the flue 6, make the eyeglass at probe two ends not be vulnerable to the pollution and the corrosion of flue gas, and the diameter of fixed bar 8 is little, the accumulation and the rate of set of flue dust have been reduced widely, prolong the serviceable life and the maintenance period of probe greatly, reduced maintenance workload.
Claims (2)
1, a kind of smoke gas on-line monitor measuring sonde; comprise corner reflector [9] and to coming and going the air purge set that the minute surface of outgoing front window mirror [1] that light path links, corner reflector [9] is protected with light; it is characterized in that described outgoing front window mirror, corner reflector are respectively equipped with separate air purge set; and be separately positioned on the both sides of flue [6], be connected by fixed bar [8] between two air purge sets.
2, smoke gas on-line monitor measuring sonde according to claim 1 is characterized in that the air purge set rear end at corner reflector [9] place is provided with the end cap [11] that makes things convenient for corner reflector [9] to take out.
