Specific embodiment
As shown in Figure 1, the medium in impregnating autoclave 100 passes through dielectric film filter in the prior art after the completion of pipe tobacco pipe tobacco dipping
Pipe 7 recycles.Pipe tobacco after dipping enters conveying equipment 200, sets after conveying equipment 200 breaks up vibration into microwave heating
Standby, the heating in microwave equipment makes the increase of pipe tobacco volume reach expansion cigarette so that the media expansion vaporization being immersed in inside pipe tobacco
The effect of silk.However the pipe tobacco surface after impregnating is stained with medium, is also saturated with inflating medium inside pipe tobacco, these inflating mediums are passing
The medium that pipe tobacco surface is stained on during defeated can vaporize volatilization a part, and the medium on pipe tobacco surface is stained in microwave expansion equipment
With the medium that is immersed in inside pipe tobacco can whole carburation by evaporations, be all lost after the vaporization of these media and enter air, without returning
It receives.A large amount of wastes of medium are caused, inflating medium dosage greatly increases, and inflating medium is expensive, and the cost of pipe tobacco production is big
Big improve is exerted heavy pressures on.
Embodiment one
As shown in Fig. 2, present invention consideration returns the dielectric gas of vaporization in the conveying section of tobacco shred immersion and expansion arc
It receives, adds exhaust pipe 4 on conveying equipment 200 and bloating plant 300 (must carry out to conveying equipment 200 and bloating plant closed)
It is evacuated with negative pressure device.Concrete mode is that a kind of pipe tobacco dipping expansion system, including conveying equipment 200, the conveying are set
Standby 200 tops are provided with impregnating autoclave 100, and 200 lower end of conveying equipment is connect with tobacco shred expansion equipment 300, the impregnating autoclave
100 lower parts are connect by dielectric film filter pipe 7 with medium basin 10, and 100 top of impregnating autoclave passes through medium with medium basin 10
Spray tube 8 connects, it is characterised in that the conveying equipment 200 and/or the tobacco shred expansion equipment 300 pass through exhaust pipe 4 and one
Negative pressure equipment connection, the negative pressure equipment outlet are connect by secondary media recovery tube 6 with medium basin 10.
As shown in FIG. 7 and 8, the negative pressure equipment can connect with only conveying equipment 200 or only connect with tobacco shred expansion equipment 300
It connects, can also be connect simultaneously with the two, as shown in Figure 2 the scheme of the preferred the two of present invention connection simultaneously.
Embodiment two
In the present embodiment, specifically, the negative pressure equipment is a vacuum compressor 5, its object is to generate negative pressure and right
The gaseous medium of extraction carries out compression processing, and gaseous medium is promoted to be condensed into liquid medium at relatively high temperatures.
Specifically, being provided with condenser 61 on the secondary media recovery tube 6 of the outlet of vacuum compressor 5 connection.Its purpose
It is, the gaseous medium part after compressor compresses is condensed into liquid but there is also part gaseous mediums, carries out to it cold
Solidifying processing, specific condenser 61 use water cooling, and water temperature is at 10-15 °, because the pressure that vacuum compressor 5 provides, is not required to
Whole media can be condensed into liquid by temperature that will be very low, but be also mixed in liquid medium at this time part on-condensible gas and
Condensed water must be further processed.
Specifically, being provided in part of the secondary media recovery tube 6 between condenser 61 and medium basin 10
Pressure medium basin 62.It is intended that due to by being mixed with on-condensible gas and condensed water in condensed liquid medium, it will be cold
Liquid medium stratification in pressure medium basin 62 after solidifying, liquid medium is in lower layer, and in middle level, on-condensible gas exists condensed water
Condensed water and on-condensible gas, the liquid medium after being purified is discharged in upper layer.Liquid medium is sent by secondary media recovery tube 6
It is recycled to medium basin 10.
In order to realize better gaseous medium recovering effect, the doping air for keeping gaseous medium removal process as few as possible and
Impurity needs to optimize setting to conveying equipment 200 and tobacco shred expansion equipment 300.In conveying equipment 200 and impregnating autoclave 100
Junction be sealed, and interconnecting piece between the upper and lower chambers of conveying equipment 200 carries out seamless seal setting.And defeated
It send and adds heater 225 in equipment 200.Expanding chamber 310 is arranged to microwave expansion equipment, and to conveying equipment 200 and expanding chamber

Embodiment five
In the present embodiment, about the selection of 5 compression horsepower of vacuum compressor, the main reason for considering dielectric loss is needed.
The loss of tobacco expanding medium is related with the saturated vapor pressure of the air capacity and medium itself that enter system.
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:
| Volume/m3 | 0.1 | 1.0 | 3 | 5 | 10 | 25 | 50 | 100 | 200 |
| Air average leaked | 0.1~ | 0.5~ | 1~ | 2~ | 3~ | 4~ | 5~ | 8~ | 10~30 |
| Amount/kg/h | 0.5 | 1.0 | 2 | 4 | 6 | 8 | 10 | 20 |
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.
Embodiment in above-described embodiment can be further combined or replace, and embodiment is only to of the invention
Preferred embodiment is described, and it is not intended to limit the concept and scope of the present invention, is not departing from design philosophy of the present invention
Under the premise of, the various changes and modifications that professional and technical personnel in the art make technical solution of the present invention belong to this hair
Bright protection scope.
