Abstract
The utility model relates to an analytical pool for on-line measuring petroleum product absorption spectrum. Can thoroughly eliminate air bubbles contained in the sample and can make accurate analysis data on the sample. The method is technically characterized in that a sample enters a buffer from a sample inlet, the buffer has the functions of filtering and buffering the sample containing air bubbles, when the flow of the sample flowing through an optical path is constant, the flow of a sample outlet is smaller than that of the sample inlet, a certain liquid level is maintained in a cavity, the air bubbles float on the liquid level and are discharged through an overflow hole, impurities and air bubbles in the sample analyzed in the cavity are eliminated, and the accuracy and reliability of the online instrument sample analysis are ensured.
Description
Technical field:
The utility model belongs to parts in the device for the optical evaluation, a kind of specifically analysis cell that is used for on-line measurement petroleum products absorption spectrum.
Prior art:
In prior art, the general analysis pool structure is as follows: its shape mostly is right cylinder or cube, have a logical light light path on the axis direction in the analysis cell main body, two ends in logical light light path, lens that have gland bonnet respectively are housed, two ends at the close lens in the side of analysis cell, respectively open a sample that leads to the light light path and import and export, go out under its sample is enterprising, sample flows into logical light light path by injection port, carry out on-line measurement, because sample is a petroleum products, petroleum products is in flow process, and self can produce bubble, illumination is mapped on the bubble can produce scattering, has caused wrong analysis result.In addition through patent retrieval, patent specification 85202750 " error that disappears formula flow colorimetric pond " discloses a kind of colorimetric pool, it is the size by the restriction measuring beam, makes the central area of light beam through the light hole road, thereby avoids bubble and small solid impurity stopping measuring beam on the inwall.
Summary of the invention:
The purpose of this utility model just provides a kind of supporting use of instrument for on-line measurement petroleum products spectral quality, can thoroughly eliminate the problem that contains bubble in the sample, and can make the analysis cell of accurate analysis data.
The purpose of this utility model realizes by following scheme: close in analysis cell main body 1
Bottom position has a logical light light path, at the two ends of logical light light path, lens that have gland bonnet is housed respectively, and input mode is: by analysis cell top sample introduction, the bottom goes out sample.The characteristics of this programme are: sample is by sample inlet 6, enter impact damper 9,9 pairs in impact damper band is pressed and the sample that contains bubble rises and filters and buffer action, sample enters cavity 8 by impact damper 9 outsides, when the pressure in the cavity 8 is consistent with ambient pressure, make the sample flow of the light-path of flowing through constant, 7 places have increased the hole 12 of damming at sample export, make the flow of the flow of sample export 7, keep certain liquid level in the cavity 8, because bubble density is less than sample rate less than sample inlet 6, bubble floats on the liquid level, discharge through spout hole 11, eliminated impurity and bubble in the cavity 8 inner analysis samples, guaranteed the accuracy and the reliability of in-line meter sample analysis.
The utility model compared with prior art its characteristics is, the size of light signal just increases by an impact damper in original analysis cell without limits, opens spout hole in housing depth 2/3 above position, thoroughly solve optical channel and had bubble, influenced measurement accuracy and on-line measurement problem.The accuracy and the reliability of auto injection and continuous coverage, on-line analysis have been improved.
Description of drawings:
The drawing explanation of accompanying drawing
Fig. 1 is the stereographic map of the analysis cell of on-line measurement petroleum products absorption spectrum
Fig. 2 is the cut-open view of the analysis cell of on-line measurement petroleum products absorption spectrum
Its each component names is as follows: 1, analysis cell main body 2, lens 3, gland bonnet
4, O-ring seal 5, light path 6, sample inlet 7, sample export 8, cavity
9, impact damper 10, analysis cell lid 11, spout hole 12, the hole of damming
Specific embodiment:
Referring to accompanying drawing, the analysis cell of the on-line measurement petroleum products absorption spectrum in the present embodiment, in the online spectroanalysis instrument of my unit development, be applied, the quality of analysis cell structural design directly influences the sample analysis precision, we have adopted preferred plan for this reason, and sample enters impact damper 9 by sample inlet 6, impact damper 9 can press screen pack by gland bonnet with holes up and down to be formed, and also can one baffle plate be installed by light path upper fixed in the cavity and form.9 pairs in impact damper band is pressed and the sample that contains bubble rises and filters and buffer action, sample enters cavity 8 by impact damper 9 outsides, when the pressure in the cavity 8 is consistent with ambient pressure, its sample flow is constant, 7 places have increased the hole 12 of damming at sample export, make the flow of the flow of sample export 7 less than sample inlet 6, keep certain liquid level in the cavity 8, because bubble density is less than sample rate, bubble floats on the liquid level, discharge through spout hole 11, eliminated impurity and bubble in the cavity 8 inner analysis samples, guaranteed the accuracy and the reliability of in-line meter sample analysis.This instrument is in experimentation, and find analyzing has abnormal conditions, and good seal do not have leakage, and highly sensitive, measuring accuracy satisfies the GB requirement, for the optimal control of process units provides reliable assurance.
Claims (2)
1, a kind of analysis cell that is used for on-line measurement petroleum products absorption spectrum, comprise an analysis cell main body, have a logical light light path on the axis direction in the analysis cell main body, two ends in logical light light path, lens that have gland bonnet respectively are housed, two ends at the close lens in the side of analysis cell, respectively opening a sample that leads to the light light path imports and exports, go out under its sample is enterprising, sample flows into logical light light path by injection port, it is characterized in that sample is by sample inlet (6), enter impact damper (9), impact damper (9) is pressed band and the sample that contains bubble rises and filters and buffer action, sample enters cavity (8) by impact damper (9) outside, when the pressure in the cavity (8) is consistent with ambient pressure, make the sample flow of the light-path of flowing through constant, locate to have increased the hole (12) of damming at sample export (7), make the flow of the flow of sample export (7) less than sample inlet (6), keep certain liquid level in the cavity (8), because bubble density is less than sample rate, bubble floats on the liquid level, discharges through spout hole (11), has eliminated impurity and bubble in cavity (8) the inner analysis sample.
