Description

Technical field

The proposed utility model apparatus for measuring gas in liquids relates to methods and devices for measuring gases in liquids.

State of the art

There are various methods and devices for measuring gases in liquids (Karyukhina T.A., Churbanova I.N. Chemistry of water and microbiology: 3rd ed., Revised and added. - M.: Stroyizdat, 1995. - 208 p.

Quite common in the practice of water purification is a device using a measuring tube filled with water and turned upside down, and the open end of the tube is lowered into the water (Ed. St. USSR N9116886. A device for measuring pulp aeration. Appl. 06/27/1958, Authors: Komarova E.K., Lashkevich T.L., Kharchenko K.S. and Egorova T.L. - prototype). Gas bubbles are directed, including into the open end of the measuring tube, displacing water from the measuring tube over time. In this case, the greater the gas content of the aerated liquid, the greater the amount of water displaced by the bubbles. The volume of water displaced can be used to determine the gas content of the liquid.

A significant disadvantage of the known device is a large measurement error.

Utility Model Disclosure

The achievement of a new positive technical result is the proposed utility model in the form of a device for measuring gases in a liquid with the elimination of this drawback and obtaining experimental data with a smaller error.

The proposed utility model represents an installation for measuring gases in a liquid, including a housing divided by a partition into a base and a control chamber with measuring tubes placed inside them with air bubble generators located below them, and magnetic elements are used as a holder with the creation of a magnetic field between them with with a tension of 1000-5000 oersted and on the outer side of the body from the side of the control chamber, a pH meter and a reagent dispenser for changing the pH are installed.

Implementation of the utility model

The installation for measuring gases in a liquid (see Fig.) includes a housing 1, divided by a partition 6 into the base 2 and control 5 chambers with measuring tubes 3 and 4 of the same diameter d placed inside them, respectively, with air bubble generators 10 located below them, and magnetic elements 7 are used as a test tube holder with the creation of a magnetic field between them with a strength of 1000-5000 oersteds, and a pH 8 meter and a reagent dispenser for changing pH 9 are installed on the outer side of the housing from the side of the control chamber.

The principle of operation of the installation for measuring gases in liquids (see figure) is as follows. Both chambers, base 2 and control 5, located inside the housing 1 and separated by a partition 6, are filled with water by approximately 2/3 of their volume. In both chambers 2 and 5, measuring tubes 3 and 4, respectively, with the same diameter d, are placed inside them, with air bubble generators 10 located below them, and magnetic elements 7 are used as a tube holder with the creation of a magnetic field between them with a strength of 1000-5000 oersteds and on the outer side of the housing with control chamber 2, a pH meter 8 and a reagent dispenser for changing pH 9 are installed. Holders in the form of magnetic elements not only perform the function of fastening, but also contribute to the rapid establishment of pH due to micromixing of ions in a magnetic field. In the control chamber, using a reagent dispenser 9 and a pH meter 8, a pH value is set at which the solubility of the gas to be determined is zero. After 30 minutes in test tubes 2 and 5 there will be different amounts of gas, and in test tube 5 it will be more due to the release of dissolved gas. The relative content of the dissolved gas in the control chamber in relation to the gas released under normal conditions in the base chamber is determined by the difference between the values of H and h.

When measuring, experimental data are obtained with a measurement error of not more than 10%, and in the case of measurement using a prototype setup, the measurement error is 20-35%.
