Embodiment Construction
[0026] The embodiment of the present invention discloses a clasp of a laser gas analyzer, so as to avoid mutual reflection of laser light passing through the lens combination and then passing through the protective lens, causing signal interference, and simplifying the installation procedure.
[0027] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.
[0028] See figure 2 , figure 2 It is a schematic diagram of the structure of the snap ring of the laser gas analyzer provided by the present inv...

The invention discloses a clasp of laser gas analyzer. The clasp comprises a transmitting tube clasp, which is arranged on the exterior of the transmitting tube, and a cleaning tube clasp, which is arranged on the exterior of the cleaning tube; the transmitting tube clasp and cleaning tube clasp both have a one-piece structure; the internal walls of the one-piece type clasps are both provided with an annular step like surface for placing a protective lens, and the step like surfaces are inclined. When the step like surface and an inclined lens are combined, emitted light goes through a lens set and the protective lens in sequence, the lens set and protective lens reflects light to each other, the reflective light will not be returned to the lens set, and thus the signal interference is avoided. Because the external signal interference is reduced, the measurement becomes more precise, and data with less error can be obtained. The invention also discloses a laser gas analyzer comprising the provided clasp.
Description
Technical field [0001] The present invention relates to the technical field of gas analysis, and more specifically, to a clasp of a laser gas analyzer, and also to a laser gas analyzer including the clasp. Background technique [0002] The laser gas analysis instrument is a sophisticated instrument that contains a large number of advanced laser and electronics technologies. It adopts single-line spectroscopy technology, laser frequency scanning technology, second harmonic detection technology, spectral line broadening self-correction technology and other key technologies, which can reliably realize continuous and online gas concentration measurement. It has been widely used in steel metallurgy, petrochemical and other industries. The basic measurement method is: the laser emitted from the emission unit on one side of the flue is received by the receiver of the receiving unit through the gas to be measured. Therefore, the concentration of the gas to be measured can be calculated...
