Loss with entrance system air capacity and medium itself saturated vapor pressure it is related.
In order to calculate dielectric loss amount during compression process, need first to determine the air into system confined space
Amount.There are two types of situations for the calculating of air license amount, close one is entering after system works multiple circulations, in single working cycles
Close the air capacity of system；Another kind is the air capacity for entering cold closed system in system first job recycles.The previous case
Calculated value it is smaller, guard for the sake of, by latter situation calculating.
The air capacity that closed system can be entered has two parts:
(1) system confined space remaining air after injection evacuates.Sealing Arrangement gross space is based on 50m3, then basis
The evacuation pressure of 20kPa estimates that tolerance is 50 × 0.2 × 1.205=12.05kg.
(2) air of equipment is leak into from the static seal of Sealing Arrangement and dynamic sealing.According to " chemical process safety handbook-
The first volume " table 19-38 give the empirical relation of vacuum system volume and leakage rate, be as follows:
According to the table, Sealing Arrangement gross space is 50m3, and corresponding air leakage rate is about 5~10kg/h, considers connection
The leakage of section and pipeline, total leakage quantity is based on 7.95kg in the working cycles of 1h.For single batch expanded cut tobacco, air is total
Amount is estimated as 12.05+7.95=20kg.
Condensation temperature is 98kPa, the i.e. partial pressure of medium by 14 DEG C of calculating, the saturated vapor pressure of corresponding medium are as follows:.Medium row
It is high-volume calculated according to air total amount, saturated vapor pressure and compression pressure, if compression pressure is, then air divides are as follows:, due to medium
The Van der Waals constant and virial coefficient of vapour are difficult to obtain, but in the case where pressure is not high, are calculated by perfect gas, error
It is limited, therefore, is obtained according to The Ideal-Gas Equation:
Compression pressure 0.7MPa (700kPa)
Discharge gas in medium amount be
Compression pressure 1.0MPa (1000kPa)
Discharge gas in medium amount be
Compression pressure 1.5MPa (1500kPa)
Discharge gas in medium amount be
From above-mentioned calculated result it is found that when compression pressure be 0.7MPa when, to single batch production 300kg expanded cut tobacco,
Dielectric loss amount is 15.04kg, relatively original 112kg, and medium consumption percentage drops to 5.0% by 37.2%, effect ten
Divide significantly, if compression pressure improves again, dielectric loss amount can be lower.But consider 5 performance of vacuum compressor and equipment economy,
It is more reasonable that compressing force is set as 0.7MPa.
