Abstract
The present utility model provides a beam-focusing device for monitoring denitration ammonia escape of a thermal power plant. The device comprises an emission unit and a receiving unit, the emission unit comprises a diode laser and an instrument window, the receiving unit comprises a detector, a probe insert tube and a purge port; the emission unit and the receiving unit respectively comprise a corrugated pipe, two sides of the corrugated pipe are welding flanges, the middle part is a spring, the corrugated pipe is fixed with the welding flanges through an upper bolt, a lower bolt, a left bolt and a right bolt, internal and external sides of the upper bolt, the lower bolt, the left bolt and the right bolt are all fixed with nuts, the internal sides of the welding flanges, which are close to a flue, are fastened through nuts, the four nuts of the external side of the corrugated pipe are movably connected, and the four nuts of the external side of the corrugated pipe are used to change beam-focusing angle. The beam-focusing device for monitoring denitration ammonia escape of the thermal power plant can be used for realizing beam focusing accurately and stabilizing transmittance, thus measured values of an instrument is more accurate.
Description
Technical field
The utility model relates to a kind of corrugated tube to optical tech, is specifically related to be used for the alignment device of fuel-burning power plant denitration the escaping of ammonia monitoring.
Background technology
Big because of fuel-burning power plant denitration exhaust pass, dust concentration is high, temperature is high, platform shake severe, the reasons such as making the flue distortion of expanding with heat and contract with cold, existing the escaping of ammonia monitor penetrability is unstable.Even transmitter unit and receiving element are very accurate to getting in cold conditions, when unit operation, still there is deviation in they to light.
The utility model content
The alignment device that is used for the monitoring of fuel-burning power plant denitration the escaping of ammonia that the utility model provides, penetrability is stable, and optical noise is lower, makes that the instrument measurement value is more accurate.
To achieve these goals, the utility model is realized through following technical scheme:
Be used for the alignment device of fuel-burning power plant denitration the escaping of ammonia monitoring, comprise transmitter unit and receiving element, said transmitter unit comprises diode laser, instrument form, and said receiving element comprises detecting device, probe tubular stinger and purging mouth; Said transmitter unit and receiving element comprise corrugated tube respectively; Said corrugated tube both sides are that welding flange, centre are spring; Between said corrugated tube and the welding flange through last bolt, down bolt, left bolt and right bolt; Fixed by nut is all adopted in the said interior outside of going up bolt, following bolt, left bolt and right bolt, and welding flange is fastening near the inboard nut of flue, and four nuts in the corrugated tube outside are for flexibly connecting.
As a kind of preferred version of the utility model, said welding flange is identical with the pore size of the flue flange that needs monitoring.
When cold conditions, earlier welding flange is aimed at, behind unit starting,, can regulate through corrugated tube if deviation is arranged.Specifically be, change angular through four nuts outside the corrugated tube, after accurate, again that all nuts in the outside are fastening to light.
The alignment device that is used for the monitoring of fuel-burning power plant denitration the escaping of ammonia that the utility model provides can be accurately to light, and penetrability is stable, makes that the instrument measurement value is more accurate.
Description of drawings
Fig. 1 is used for the overall schematic of the alignment device of fuel-burning power plant denitration the escaping of ammonia monitoring for the utility model.
Fig. 2 is the sectional view of corrugated tube in the utility model.
Fig. 3 is the cut-away view of corrugated tube in the utility model.
Reference numeral: bolt on 1,2 right bolts, 3 times bolts, 4 left bolts, 5 corrugated tubes, 6 welding flanges, 7 transmitter units, 701 instrument forms, 702 diode lasers, 8 receiving elements, 801 detecting devices, 802 purge mouth, 803 probe tubular stingers.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
The utility model fuel-burning power plant denitration the escaping of ammonia monitor comprises transmitter unit 7 and receiving element 8, and transmitter unit 7 comprises diode laser 702, instrument form 701, and receiving element 8 comprises detecting device 801, probe tubular stinger 803 and purging mouth 802; Transmitter unit 7 comprises corrugated tube 5 respectively with receiving element 8, and corrugated tube 5 both sides are that welding flange 6, centre are spring, and welding flange 6 is identical with the pore size of flue flange.Between corrugated tube 5 and the welding flange 6 through last bolt 1, bolt 3, left bolt 4 are fixing with right bolt 2 down; Last bolt 1, bolt 3, left bolt 4 all adopt fixed by nut with the interior outside of right bolt 2 down; Welding flange 6 is fastening near the inboard nut of flue, and four nuts in the corrugated tube outside are for flexibly connecting.
When cold conditions, earlier transmitter unit 7 is aimed at the welding flange 6 of receiving element 8, behind unit starting; Deviation is arranged slightly, can regulate, promptly change angular through four nuts regulating corrugated tube 5 outsides through corrugated tube 5; After accurate, again that all nuts in the outside are fastening to light.
As finding to have when inclined to one side down, our corresponding outside nut of bolt on the corrugated tube 1 of just screwing makes whole prolongation Guan Shangyi; When left avertence, the outside nut of right bolt 2 correspondences of the corrugated tube of just screwing moves to right whole prolongation pipe, and the rest may be inferred.Slightly regulate left and right sides corrugated tube through this method, again that all nuts are fastening after accurate to light, thus solved optical issue.
Claims (2)
1. be used for the alignment device of fuel-burning power plant denitration the escaping of ammonia monitoring, comprise transmitter unit and receiving element, said transmitter unit comprises diode laser, instrument form, and said receiving element comprises detecting device, probe tubular stinger and purging mouth; It is characterized in that: said transmitter unit and receiving element comprise corrugated tube respectively; Said corrugated tube both sides are that welding flange, centre are spring; Between said corrugated tube and the welding flange through last bolt, down bolt, left bolt and right bolt; Fixed by nut is all adopted in the said interior outside of going up bolt, following bolt, left bolt and right bolt, and welding flange is fastening near the inboard nut of flue, and four nuts in the corrugated tube outside are for flexibly connecting.
2. the alignment device that is used for the monitoring of fuel-burning power plant denitration the escaping of ammonia according to claim 1 is characterized in that: said welding flange is identical with the pore size of the flue flange that needs monitoring.
