Abstract
The invention provides a low-temperature stability analyzing apparatus for methanol gasoline. The apparatus comprises: a low temperature bath; a sample holder, wherein the sample holder is arranged at the central part of the low temperature bath, the upper part of the sample holder is provided with a seal cover, and two sides of the sample holder are provided with two corresponding lenses highly pervious to light; a refrigeration compressor which is connected with a refrigeration helix tube located in the low temperature bath; a magnetic stirrer which is mounted at the bottom of the low temperature bath; a circulating pump which is communicated with the low temperature bath through a circulating pipeline; a radiator which is connected with the circulating pipeline; two glass tubes which respectively pass through a through hole in the low temperature bath, wherein one end of each glass tube is in seal connection with the low temperature bath, and the other end of the glass tube is connected with the sample holder; a photosensitive diode which is located out of the through hole at one side of the low temperature bath; a light emitting diode which is located out of the through hole at the other side of the low temperature bath; a lens which is located between the light emitting diode and the through hole at the other side; two temperature sensors; a one-chip microcomputer; and a display screen used for outputting and displaying a minimum temperature for evaluating sample stability.
Description
technical field [0001] The invention relates to a low-temperature stability analysis device for methanol gasoline, which is suitable for low-temperature stability analysis and detection of medium and low-proportion methanol-gasoline, especially for low-proportion methanol-gasoline stability analysis, and provides convenience for the research and detection of methanol gasoline low-temperature stability . Background technique [0002] With the reduction of oil reserves and the improvement of environmental protection requirements, the development and utilization of new renewable energy has become an inevitable trend. Methanol mixed with a certain proportion of gasoline has been widely used as a vehicle energy source. The advantage of methanol is that it can effectively increase the octane number of gasoline, and at the same time make gasoline burn more completely, increase combustion efficiency, improve economy, and reduce air pollution; the disadvantage is that methanol has a...
