Abstract

The invention provides a control apparatus of gas-liquid mixing and evaporation for a combustion experiment, comprising an oil bath heating and heat keeping mechanism, a three-way gas-liquid mixing mechanism, a gas conveying mechanism and a liquid conveying mechanism. The oil bath heating and heat keeping mechanism comprises an electronic constant temperature oil bath pot with heat exchange medium; the three-way gas-liquid mixing mechanism is arranged in the electronic constant temperature oil bath pot; the gas conveying mechanism comprises a gas conveying conduit and a gas mass flow controller; the liquid conveying mechanism comprises a liquid conveying conduit and a liquid flow controller; one ends of the gas conveying conduit and the liquid conveying conduit are separately connected with the gas inlet and the liquid inlet of the three-way gas-liquid mixing mechanism; the other ends are separately connected with the gas mass flow controller and the liquid flow controller; the gas-liquid mixing outlet of the three-way gas-liquid mixing mechanism is connected with a mixed gas output conduit. The control apparatus gas-liquid mixing and evaporation for a combustion experiment has theadvantages of simple structure, convenient operation and low cost.

Description

technical field [0001] The invention belongs to the technical field of unmanned vehicles, and in particular relates to a gas-liquid mixing evaporation control device for combustion experiments. Background technique [0002] In basic combustion research, due to the research purpose and experimental requirements, it is usually necessary to heat the liquid to evaporate and mix it with the gas in a certain proportion. At present, experimental liquid fuel evaporation devices in basic combustion research usually use commercially integrated gas-liquid mixed evaporation control systems, which generally include a liquid flow meter, a carrier gas mass flow controller, a three-way mixing valve and several evaporators. part. However, the evaporation control system has high cost, complicated maintenance and poor economy. Therefore, there is an urgent need for a gas-liquid mixed evaporation device with simple structure, convenient operation and low cost as a substitute for the system. ...
