External pressure difference is too big and cracked or makes 17 gas leakage of sealing ring, improves safety.
It is taken away in the gas process in reaction cup 31 in intermittence, vacuum state is formed in reaction cup 31, due to vacuum shape
The boiling point of solution reduces under state, improves the evaporation rate of organic solvent, the gas build that organic solvent volatilizes to gas tank 41
In, the pressure in gas tank 41 is gradually increased, when the gas flow in gas tank 41 reaches the explosion limit of normal hexane, in gas tank 41
Gas makes the sparking of piezoelectric ceramic ignitor 44 generate spark to opening pressure valve 43, and spark will overflow the gas ignition of gas tank 41,
The gas for avoiding organic solvent volatilization is entered in reviewer's body by aerial respiration, and reviewer is prevented to be poisoned.
In order to which the mixing between the quantitative oxygen and organic solvent volatile gas body that allow in gas tank 41 reaches explosion limit, normal hexane
Explosion limit be 1.18%~7.4% (volume fraction), according to chemical theory volume fraction approximate calculation, explosion gas is complete
When burning, chemical theory volume fraction may be used to determine the lower explosion limit of paraffinic, formula LUnder≈ 0.55c0, c0 are quick-fried
Chemical theory volume fraction when fried gas completely burned, if oxysome fraction is based on 2.0% in air, c0 can use formula c0=2/
(0.02+n0) is determined, requisite oxygen molecular number when n0 is fuel gas completely burned, thus determines the number for prestoring quantitative oxygen
It measures, has prestored quantitative oxygen in gas tank 41, the volatilization gas for being then pumped into organic solution is mixed, when volatilization gas reaches quick-fried
It overflows and lights when the amount of the fried limit, volatilization gas constantly accumulates storage, when the volatilization gas of accumulation storage reaches explosion limit
The processing that toxic gas can be completed, error caused by avoiding the amount of volatilization gas from being unable to measure.
