Description
The present invention relates to contain in a kind of being used for the device of cooling at the groove of viscous liquid sample, the particularly oil product of from+50 to-120 ℃ temperature range analysis.
At some in particular cases, relate to the petroleum product analysis field the experiment of some physical-chemical need with analysis vat and wherein the sample of splendid attire be cooled to temperature until-80 ℃ even-120 ℃; The mensuration of enumerating by nonrestrictive example in these experiments has: temperature, dew point, pour point, cloud point or Tag and Abel (Abel) flash-point can be filtered in the border.
Be this purpose, usually use the device of type as shown in Figure 1, this device is made up of the circulate EGR 2 of this fluid of Rankine (rankine) the formula cryostat 1 collaborative direction with arrow a that has been equipped with one jar of cooling thermal liquid, and this EGR also comprises circulating pump 3.
Closed circuit 2 is to be made of the coil pipe 4 around the groove 5 that is cooled.Its assembling is that coil pipe 4 and the groove 5 that is cooled are put into the heat shield 6 that includes heat-insulating material 7.Hygrosensor 8 can be measured the variations in temperature of groove 5 at any time.
This conventional equipment that is cooled off by the groove of containing sample in contacting with the coil pipe that includes circulation heat transport fluid has many defectives.
What should particularly point out is groove to be cooled to-80 ℃ of temperature need adopt almost-85 ℃～-90 ℃ thermal liquid, and this need use two-stage Rankine (rankine) type generator; Now, this cryogenerator be heavy, be full of noise and flimsy device.
In addition, for cooling bath, must obtain one jar of thermal liquid, it can keep fluid state under very low temperature; At present all used methyl alcohol basically for this purpose, this is because also can consider that other the got liquid that uses is not too expensive, is exactly volatile at ambient temperature.Now, because the toxicity of methyl alcohol will forbid in the near future that probably it uses in the laboratory.
In addition, because the easily damaged relatively property of Rankine (rankine) type cryogenerator does not contain this generator, the adiabatic connecting line that this need be connected with the latter in the analyzer now; Now, these connecting lines are high risk roots of leakage and heat loss, and therefore the whole efficient of this low-temperature receiver type is very low.
Should also be noted that the groove temperature controlling is difficult to carry out owing to can get the thermal shock that does not match and be applied to groove when injecting heat transport fluid of energy and institute's energy requirement at every turn.
The purpose of this invention is to provide a kind of device, this device can accomplish the fluid sample that interior Sheng is to be analyzed particularly the groove of oil product be cooled to very low temperature, and overcome above-mentioned shortcoming.
For reaching this purpose, the present invention relates to a kind of device, it is characterized in that it comprises the Stirling circulation (Stirling cycle) of a pulse gas cooling device on the one hand, also comprise on the other hand one be placed on this cooling device and with the synergistic dry contact of the groove heat transmitter spare that includes analyzed sample so that sample can be cooled to temperature required.Stirling circulation or pulsed gas quench system are for being cooled to electronic component the special design of low-down temperature, this device is pressed shown in the figure and is made up of the collaborative condenser pipe of a compression member, it links to each other with AC power, and be provided with the device that can change high-pressure working gas (particularly helium) pressure periodically, this gas is full of working chamber, and this working chamber is divided into many compartment that stretch into compression member and condenser pipe; So just may working gas be expanded can access the very low temperature of this level in the opposite end of the condenser pipe that is arranged in relative compression member or the chilling room compartment of head end.
According to the present invention, dry contact heat transmitter spare is arranged on the condenser pipe, and concordant with this condenser pipe head end.
The experiment that the structure of these heat transmitter spares is carried out according to needs and changing.
According to a kind of variation of the present invention, defer to European standard pr EN No. 16, the example that oil product border filtrability temperature is measured is illustrated by being suitable for, heat transmitter spare is by metal tube (particularly copper pipe), constitute around the sheath of the groove of the analyzed sample of interior Sheng and the sleeve that is manufactured from the same material on this sheath sidewall, the shape and size of this sheath are corresponding with the head end of condenser pipe, and are installed on this head end.
Change according to this, tubular sheath and energy be installed to the inside that top condenser pipe head end is fixed on the insulated cabinet that includes heat-insulating material with this protective metal shell.
The structure of heat transmitter spare certainly can be different fully, and this depends on the experiment that will carry out and the type of therefore desiring cooling bath.
In all cases, for heat transmitter spare provides hygrosensor, it and Control Component synergy is so that the temperature of regulating tank well.
Or rather, the Stirling cooling back installation generally includes a cylindrical basically compression member and a condenser pipe, and this condenser pipe also is columniform basically, be positioned at the extension of compression member and coaxial with this compression member, but diameter is smaller.
This compression member comprises a main piston at least, and this piston is controlled by the linear or rotary motor of ac power supply, and moves back and forth with compression work gas in compression compartment.Condenser pipe itself contains an oscillating-piston hollow and that fill heat exchange medium (sweeping piston), this piston is flexibly installed, it is with the frequency identical with main piston but with opposite phases motion, and with the pressure of main piston synergy with different interval chamber working gas in the periodic variation working chamber; This oscillating-piston is divided into the compartment that two energy are interconnected by heat exchange medium in condenser pipe inside, promptly one is the cold compartment that is positioned at the head end of condenser pipe, another is the hot compartment that is positioned at this condenser pipe offside one end, and it links to each other with compression compartment.
Such cooling device himself has been known, and for example its structure is open in 8288 aspect file US-A-4894996 and US-A-508, but for for simplicity, just is not described in greater detail in this application.
