Abstract
The invention discloses a sample cell of a monitor apparatus for inline calibration, relating to inline monitoring techniques field; and the technical problems to be solved are to simplify the structure of the inline monitor apparatus, lower the cost and reduce the cubage; wherein, glass windows at the front and the rear edge of the sample cell are specially designed lens respectively, and the lens can be various lens, lens combination or lens group such as concave lens, plate lens, convex lens and so on; the lens are designed according to the requirements of the structural design of the apparatus, such as the wavelength range of tested light, needed focal length, achromatism, and aberration and so on. The present invention is characterized by simplifying the structure of the monitor apparatus, lowering the cost, and reducing the cubage.
Description
Technical field
The present invention relates to on-line monitoring technique, particularly relate to a kind of technology that is used for on-line proving and verification on-line monitoring discharging flue gas instrument sample cell.
Background technology
The on-line monitoring of discharging flue gas is the importance of environmental protection.In discharging smoke gas on-line monitor device, it is important how to realize the on-line proving and the verification of instrument.Generally in the instrument that adopts optical method for measuring, as based on the difference spectrum technology, an on-line proving sample cell is set all in the instruments design of infrared technique etc., the two ends of this sample cell are to allow the permeable optical plate glass window of measuring beam, are arranged in parallel.When allowing ultraviolet light see through, this windowpane is generally used quartz glass.
At the timing signal that carries out instrument, measuring beam advances sample cell from an end windowpane incident of sample cell, by behind the tested gas in the sample cell from the windowpane outgoing of the sample cell other end, enter spectroscopic analysis system, as monochromator or fiber spectrometer etc.Obtain high light utilization efficiency as far as possible for making, generally incident light is become directional light after through lens and reenter and be mapped to sample cell.After transmitting from sample cell, measuring light converges laggardly to go into spectroscopic analysis system or enter spectrometer through a condenser lens again by optical fiber.Such arrangement makes the structure more complicated of total system, and volume is bigger, has limited the application that system dimension is had the occasion of requirement.
Summary of the invention
At the defective that exists in the above-mentioned prior art, technical matters to be solved by this invention provides a kind of structure that can simplify online monitoring instrument, reduces cost, and reduces the sample cell that is used for on-line proving of the monitoring instrument of volume.
In order to solve the problems of the technologies described above, the sample cell that is used for on-line proving of a kind of monitoring instrument provided by the present invention is characterized in that, at least one end is provided with lens in two ends of sample cell.
Further, described lens comprise convex lens, concavees lens.
Further, described lens comprise compound lens or lens combination.
Utilize the sample cell that is used for on-line proving of monitoring instrument provided by the invention, because the structure that has adopted flat glass window and front and back lens with the sample cell two ends to combine, make sample cell can simplify the structure of online monitoring instrument, reduce cost, reduce volume.
