Problems solved by technology

[0003] At present, experiments to study ocean acidification mainly use CO 2 enricher to achieve the desired CO 2 concentration, if the experiment requires multiple different CO 2 Concentration, then correspondingly need multiple CO 2 Cylinders to provide CO 2 gas, a corresponding amount of CO is also required 2 enricher, which greatly increases the cost of the test

Abstract

The invention discloses a device for acquiring different carbon dioxide concentrations. The device comprises a CO2 storage tank, wherein the CO2 storage tank is serially connected with at least one CO2 concentration control unit in sequence through a CO2 conveying tube; the CO2 concentration control units are provided with dilution tanks; a tube inlet is formed in one side of each dilution tank; a tube outlet is formed in another side of each dilution tank; CO2 gas inlet tubes which extend to the bottoms of the dilution tanks and air inlet tubes are arranged at the tube inlets; the CO2 gas inlet tubes communicate with the CO2 conveying tube; air pumps are arranged on the air inlet tubes outside the dilution tanks; the dilution tanks are internally provided with CO2 conveying air pumps; and air outlets of the CO2 conveying air pumps are connected with diluted CO2 gas outlet tubes which extend out of the tube outlets. The device is low in equipment requirement, economic and easy to operate, convenient and precise in concentration control and applicable to tests for simulating ocean acidification.

Description

technical field [0001] The invention relates to a carbon dioxide concentration preparation device, in particular to a device for obtaining different carbon dioxide concentrations. Background technique [0002] Atmospheric CO 2 The increase in concentration causes the pH value of seawater to drop, leading to ocean acidification. The issue of ocean acidification has aroused widespread concern in the scientific community and has become an important content in the frontier field of international marine scientific research. [0003] At present, experiments to study ocean acidification mainly use CO 2 enricher to achieve the desired CO 2 concentration, if the experiment requires multiple different CO 2 Concentration, then correspondingly need multiple CO 2 Cylinders to provide CO 2 gas, a corresponding amount of CO is also required 2 enricher, which greatly increases the cost of the experiment. Contents of the invention [0004] The technical problem to be solved by the ...
