Abstract

The utility model relates to a sampling device for an ultrasonic concentration analyzer, which belongs to the technical field of an analytical instrument and is applied to an on-line ultrasonic concentration analyzer. A control valve is additionally arranged at an outlet of a measuring reservoir of the ultrasonic concentration analyzer, so as to enable the pressure in the measuring reservoir to be consistent with that of processing equipment, thereby solving the dissolving-out problem of gas in a measured medium due to pressure reduction. The sampling device can enable the ultrasonic concentration analyzer to work more reliably and stably, and can be applied to industrial on-line analysis, including such measured medium as sulfuric acid, nitric acid, ethylic acid, caustic soda and the like.

Description

Ultrasound wave concentration analyzer sampler
Technical field: the utility model belongs to technical field of analytical instruments, is specifically related to a kind of sampler of online ultrasound wave concentration analyzer.
Background technology: the ultrasonic liquid analyser is according to velocity of propagation and fluid to be measured concentration the principle with good correlativity of ultrasound wave in fluid to be measured, by measuring the velocity of propagation of ultrasound wave in fluid to be measured, realize measuring the purpose of fluid to be measured concentration.Because the rate of decay of ultrasound wave in gas phase is far longer than the rate of decay in liquid phase, therefore the existence of bubble will cause can't carrying out of measurement in fluid to be measured, so when wishing that ultrasound wave transmits in the fluid to be measured medium, do not have bubble to exist in the fluid to be measured medium.
Existing ultrasound wave concentration analyzer sampler is shown in Figure of description 1, usually the fluid to be measured in the industrial processes all has certain pressure and gas dissolving is arranged in wherein, if allow it directly enter in the measuring flume through sample valve, will resolve to minute bubbles owing to the gas that was dissolved in originally in the fluid to be measured that reduces suddenly to cause of pressure, be suspended in the measured medium, these are present in the operate as normal that bubble in the measuring flume will have a strong impact on the ultrasonic liquid analyser, even feasible measurement can't be carried out.
Summary of the invention: the purpose of this utility model is because the depressurization of sample valve for solving present ultrasound wave concentration analyzer, causing gas in the measured medium to resolve to micro-bubble is present in the measuring flume, influence the problem of ultrasound wave concentration analyzer operate as normal, make ultrasound wave concentration analyzer on-line operation steadily in the long term.
Main technical schemes of the present utility model is to set up flow control valve in the measuring flume outlet of existing ultrasound wave concentration analyzer.
The course of work of the present utility model is as follows: when sampling system is not worked, close sample cock, the fluid to be measured medium is turned off.When sampling system is worked, at first open sample valve, and sample valve leaves as far as possible greatly.Gradually open the by-pass valve control of outlet then, make the flow of sampling system reach requirement, the size of flow is regulated by the control of export valve.Because sample valve is in full-gear, and the pressure of measuring flume is consistent with the pressure in the process equipment, resolve like this, make the on-line measurement of ultrasonic liquid analyser stable more, reliable thereby avoided producing bubble owing to reducing pressure.
Description of drawings: accompanying drawing 1 is existing ultrasound wave concentration analyzer sampler synoptic diagram;
Accompanying drawing 2 is the system architecture synoptic diagram of the utility model embodiment.
In the accompanying drawing, 1---process pipeline; 2---sample valve; 3---measuring flume; 4---operation valve.
Embodiment: the utility model is described in detail below in conjunction with embodiment.
Embodiment: present embodiment be one at the ultrasound wave concentration analyzer to the improvement of the existing sampling mode of measured medium and propose, the sampler after it improves is that the outlet at measuring flume 3 increases a rate of discharge by-pass valve control 4.
Its course of work is as follows: when sampling system is not worked, close sample cock 2, the fluid to be measured medium is turned off.When sampling system is worked, at first open sample valve 2, and sample valve 2 leaves as far as possible greatly.Gradually open the by-pass valve control 4 of outlet then, make the flow of sampling system reach requirement, the size of flow is regulated by control of export valve 4.Like this because sample valve 2 is in full-gear, and the pressure of measuring flume 3 is consistent with the pressure in the process equipment, thereby avoided, made the on-line measurement of ultrasonic liquid analyser stablize more, reliably because decompression produces bubble parsing.
The utility model method can make ultrasonic concentration line Measurement and analysis instrument work more effectively.Ultrasonic concentration analyzer based on the utility model method can be applied to industrial on-line analysis, as multiple measured mediums such as sulfuric acid, nitric acid, acetic acid, caustic soda.
