Description

Technical Field

[0001] This utility model relates to the field of instruments and equipment for vapor adsorption testing, and specifically to a vapor generator with a condensation reflux structure. Background Technology

[0002] A vapor adsorption analyzer passes a vapor of a certain concentration through a sample and then measures the amount of vapor adsorbed by the sample for different concentrations using methods such as gravimetric analysis, static volumetric analysis, and temperature-programmed desorption. A specific concentration of vapor can be obtained using saturated condensation, where a carrier gas flows through a reagent bottle containing liquid, carrying supersaturated vapor out of the bottle, and then through a condenser to obtain the vapor at its saturated vapor pressure at the condensation temperature. The concentration of the vapor passing through the condenser is then calculated based on this saturated vapor pressure. However, during vapor adsorption testing, due to the long adsorption time, the liquid in the reagent bottle is consumed by the carrier gas during condensation in the condenser. If the reagent in the bottle is depleted before the test is completed, the test will fail. Utility Model Content

[0003] To overcome the problem of test failure caused by the depletion of liquid reagents in the reagent bottle, this invention proposes a steam generator with a condensation reflux structure.

[0004] The technical solution adopted by this utility model to solve its technical problem is a steam generator with a condensation reflux structure, including: a control system, a constant temperature water bath, a heater, a temperature sensor, a flow controller, and an adsorbent; the liquid outlet of the constant temperature water bath and the liquid inlet of the steam generator with the condensation reflux structure are connected by a pipeline, and the liquid inlet of the constant temperature water bath and the liquid outlet of the steam generator with the condensation reflux structure are connected by a pipeline; a reagent bottle is installed at the lower end of the steam generator with the condensation reflux structure, and a pipeline connected to the outlet of the flow controller extends to the bottom of the reagent bottle; the steam outlet of the steam generator with the condensation reflux structure is connected to the adsorbent to provide steam for the adsorbent.

[0005] The steam generator with a condensation reflux structure has a hollow spiral tube inside, through which the carrier gas controlled by the flow controller carries the steam. The spiral tube is surrounded by a heat-conducting layer, and outside this layer is a hollow flow-guiding layer. The liquid in the constant-temperature water bath can circulate within this hollow flow-guiding layer, maintaining a constant temperature for the heat-conducting layer.

[0006] The vapor generator with condensation and reflux structure is installed vertically, and the condensed liquid can be returned to the reagent bottle.

[0007] The upper part of the steam generator with condensation reflux structure has heater mounting holes and temperature sensor mounting holes.

[0008] The heater and temperature sensor are respectively installed in the heater mounting hole and temperature sensor mounting hole on the upper part of the steam generator of the condensing reflux structure. The heater is used to heat the steam generator of the condensing reflux structure, and the temperature sensor is used to detect the temperature of the steam generator of the condensing reflux structure in real time.

[0009] As can be seen from the technical solution provided by the above utility model, the embodiment of the present utility model provides a steam generator with a condensation reflux structure, which has the following advantages: during the test, the test substance condensed in the steam generator with the condensation reflux structure is refluxed back into the reagent bottle, which effectively prevents the reagent in the reagent bottle from being carried into the condenser tube by the carrier gas and being consumed by condensation, thus preventing the test from failing.
