For example, in the situation that utilize adsorption-desorption tower 4a adsorbed gasoline steam, in adsorbent cooler 13a, heat of adsorption owing to making gasoline vapour be adsorbed in adsorbent 9a, the temperature of refrigerating medium 7 rises, in adsorbent cooler 13b, the heat of desorption due to from adsorbent 9b desorption steam oil vapour the time, the temperature of refrigerating medium 7 descends.Also again flow into condensation tube 2 from refrigerating medium 7 interflow of adsorbent cooler 13a and adsorbent cooler 13b outflow respectively.
In addition, be provided with the liquid level gauge 55 for detection of the liquid level of inner refrigerating medium 7 in the side of condensation tube 2.And, be provided with the refrigerant temperature detectors 12 such as thermistor(-ter) (thermistor) for detection of the temperature of inner refrigerating medium 7, thermometer in condensation tube 2.The temperature information detected by this refrigerant temperature detector 12 is transported to diagram abridged controlling organization, and the mode maintained in prescribed limit with the temperature by refrigerating medium 7 is controlled refrigerant loop B.This controlling organization is controlled the switching of each magnetic valve, the driving frequency of each pump, the driving frequency of compressor 41, the rotating speed of air blast 46, the aperture of each pressure-reducing valve etc.
At this, the elemental motion of gasoline vapor recovery apparatus 100 is described.
At first, make refrigerant loop B action, reduce the temperature of refrigerant evaporator 44.Particularly, by drive compression machine 41, make refrigerant circulation, thereby reduce the temperature that is located at the refrigerant evaporator 44 in condensation tube 2.Now, be filled in the temperature that condensation tube 2 interior refrigerating mediums 7 are reduced to regulation.Then, when refrigerating medium 7 arrives the temperature of regulation, stop the driving of compressor 41.When the temperature of refrigerating medium 7 rises to the scope of regulation when above, restart the driving of compressor 41.
That is, diagram abridged controlling organization, according to the temperature information from refrigerant temperature detector 12, is controlled the compressor 41 of refrigerant loop B, thereby the temperature of refrigerating medium 7 is maintained to the scope of regulation.Like this, be controlled at the scope of regulation by the temperature of the refrigerating medium 7 by condensation tube 2, make gasoline vapour reclaim the ready of running.Afterwards, when adding liquified petroleum from gasoline meter 101 to automobile etc., start gasoline vapour and reclaim running.
While in the petrol tank from fuel oil supply nozzle 102 to automobile etc., adding liquified petroleum, the gasoline vapour of discharging from oil filler attracted to gasoline vapour liquefaction and reclaims in the A of loop, and gasoline vapour reclaims running to start thus.That is, the running of by forming gasoline vapour liquefaction, reclaiming the petrol pump 1 of loop A, attract gasoline vapour liquefaction to reclaim loop A gasoline vapour via fuel oil supply nozzle 102, thereby start gasoline vapour, reclaims running.The gasoline vapour that is attracted on one side in the gasoline condenser 24 condensation tube 2 in gradually cooling one side from above below the flow direction.The part liquefaction of chilled gasoline vapour is also flowed out from condensation tube 2.
The gasoline liquefied is caught, reclaims by gas-liquid separator 3, and separates from the air that comprises gasoline vapour.The liquified petroleum caught by gas-liquid separator 3 is returned in gasoline meter 101 and is again utilized.And the gasoline vapour of liquefaction does not flow into adsorption-desorption tower 4a or adsorption-desorption tower 4b.That is, owing to only in condensation tube 2, can't liquefying, reclaiming whole gasoline vapours, thus also need in adsorption-desorption tower 4a and in adsorption-desorption tower 4b, adsorb and the desorption steam oil vapour, and reclaimed.
In the situation that utilize adsorption-desorption tower 4a adsorbed gasoline steam, the 2nd magnetic valve 26a is opened to control, the 2nd magnetic valve 26b is carried out to closing control, the air of the gasoline vapour that makes to comprise effluent gases liquid/gas separator 3 flows in adsorption-desorption tower 4a.In adsorption-desorption tower 4a, utilize the adsorbent 9a adsorbed gasoline steam of the inside that is located at adsorption-desorption tower 4a.Therefore, due to adsorbed gasoline steam the air from comprising gasoline vapour, so gasoline vapour concentration reduces.For example, by adsorbent 9a adsorbed gasoline steam, make the content of gasoline vapour below 1vol%.Then, this air, via the 3rd magnetic valve 27a and the 1st pressure-reducing valve 28 that are opened and control, is discharged into atmosphere from outlet 10.
On the other hand, in adsorption-desorption tower 4b, carry out the desorb of the gasoline vapour of adsorbent 9b absorption.Particularly, by driving, separate sucking pump 5, make the air be taken into from air entry 11 by the 2nd pressure-reducing valve 31 decompressions, and flow into adsorption-desorption tower 4b via the 4th magnetic valve 32b.That is, the gasoline vapour of adsorbent 9b absorption by the air that flows into adsorption-desorption tower 4b from adsorbent 9b desorb.Then, the content that is included in airborne gasoline vapour increases (that is, gasoline vapour concentration uprises), and flows out from adsorption-desorption tower 4b, again utilizes.
The gasoline vapour flowed out from adsorption-desorption tower 4b is desorbed pump 5 and attracts, and again flows into gasoline adsorption with pipe arrangement 29(, gasoline vapour condensation/absorption loop A
1).Afterwards, with the gasoline vapour interflow flowed into from fuel oil supply nozzle 102, and flow into condensation tube 2.Like this, in gasoline vapor recovery apparatus 100, can realize the raising of the rate of recovery of gasoline vapour.In addition, the temperature in adsorption-desorption tower 4a and adsorption-desorption tower 4b being maintained to low temperature, is in order to improve condensation performance and absorption property, the temperature of refrigerating medium 7 is maintained above freezing, is in order to prevent moisture freezes involved together with gasoline vapour.
Adsorption-desorption tower 4a and adsorption-desorption tower 4b are every the volume read-out of stipulating or carry out handoff functionality according near the gasoline vapour concentration outlet of adsorption-desorption tower 4a or adsorption-desorption tower 4b.This be because, utilize the amount of the adsorbable gasoline vapour of adsorbent 9a and adsorbent 9b institute to have the boundary of regulation, in order to carry out continuous operation, need switch the sorption and desorption of gasoline vapour.In above-mentioned example, suppose to make the adsorption-desorption tower 4a played a role as adsorption tower to play a role as desorber, the situation that the adsorption-desorption tower 4b that makes to play a role as desorber plays a role as adsorption tower.Wherein, the switching of adsorption-desorption tower 4a and adsorption-desorption tower 4b is undertaken by the switching of controlling each magnetic valve.
At this, the temperature that explains the refrigerating medium 7 in condensation tube 2 maintains.
The temperature of the gasoline vapour attracted from fuel oil supply nozzle 102 is generally the temperature more than environment temperature.During gasoline condenser 24 interior conducting when this gasoline vapour at condensation tube 2, refrigerating medium 7 is heated under the effect of the condensation heat of the impact of the temperature of gasoline vapour and gasoline vapour.And, in adsorption-desorption tower 4a or adsorption-desorption tower 4b, gasoline vapour produces heat of adsorption while being adsorbed agent 9a or adsorbent 9b absorption, the refrigerating medium 7 that flows into adsorption-desorption tower 4a or adsorption-desorption tower 4b is adsorbed the heat heating.For the temperature that suppresses this refrigerating medium 7 rises and its temperature is maintained within the limits prescribed, make refrigerator 6 runnings.
In the situation that more than the temperature of the refrigerating medium 7 in the temperature information detected according to refrigerant temperature detector 12 judgement condensation tube 2 rises to the scope of regulation, diagram abridged controlling organization makes refrigerator 6 runnings, in the situation that the temperature of the refrigerating medium 7 in the temperature information detected according to refrigerant temperature detector 12 judgement condensation tube 2 is reduced in the scope of regulation, the running of refrigerator 6 is stopped.In addition, in order to prevent invading and condensation tube 2 has been implemented to adiabatic processing to the heat of condensation tube 2, thereby make this condensation tube 2 not be vulnerable to the impact of the outside air temperature varies such as high temperature exterior air, low temperature extraneous air.
But, in the situation that continue for a long time in the zubzero temperature scope such as external air temperatures such as winters, being subject to the impact of external air temperature, the temperature of the refrigerating medium 7 in condensation tube 2 is likely low than set point of temperature.An example as wherein, can list the situation that makes in the winter time gasoline service station stop for a long time.When the temperature of refrigerating medium 7 is lower than prescribed limit, with moisture freezes involved together with gasoline vapour in gasoline condenser 24 interior conductings.Like this, the pressure loss that gasoline vapour liquefaction is reclaimed in the A of loop increases, and in the worst situation, gasoline vapour liquefaction is reclaimed loop A and stopped up.Therefore, carry out the as described below moisture freezes of avoiding in gasoline vapor recovery apparatus 100 and move 1.
［ avoiding moisture freezes action 1 ］
Even in the long-term stopped process of gasoline service station, also all the time the temperature of refrigerating medium 7 is monitored, perhaps after connecting the power supply of gasoline vapor recovery apparatus 100, refueled/reclaimed before running the temperature of refrigerating medium 7 is monitored, judge that could carry out gasoline vapour reclaims and turn round.For example, the temperature that controlling organization reclaims the refrigerating medium 7 of running before starting at the judgement gasoline vapour is for example below-2 ℃ the time, stops the driving of petrol pump 1.; gasoline vapor recovery apparatus 100 is when switching to common oiling running; the moisture freezes of avoiding that adds heat run that is started refrigerating medium 7 moves 1, and above-mentioned common oiling running can be refueled and moves and do not carry out gasoline vapour and reclaim running from gasoline meter 101.
The heat release of the brine pump 8 that the refrigerating medium 7 in condensation tube 2 can produce when driving brine pump 8 is heated.Then, in the temperature of refrigerating medium 7, for example arrive+2 ℃ the time, controlling organization judgement involved moisture together with gasoline vapour does not freeze, and the action of petrol pump 1 is started.That is, switch to and can carry out moving and carrying out gasoline vapour and reclaim the running of turning round from the oiling of gasoline meter 101.By like this, in gasoline vapor recovery apparatus 100, can avoid freezing of the interior moisture of condensation tube 2.

Whether the pressure information detected by this pressure detector 70 is transported to diagram abridged controlling organization, for the temperature that judges refrigerating medium 7, be reduced to below prescribed limit.Consider when moisture freezes involved together with gasoline vapour, the pressure loss in gasoline vapour liquefaction recovery loop A increases or loop A obstruction is reclaimed in gasoline vapour liquefaction, therefore, if increase the discharge pressure of the gasoline vapour of being discharged by petrol pump 1, the burden of petrol pump 1 increases, the pressure rise detected by pressure detector 70, and the current value of supplying with to petrol pump 1 increases.Therefore, by judge pressure whether rise to setting more than or detect the variation of current value, whether the temperature that can judge refrigerating medium 7 is reduced to below prescribed limit.
For example, controlling organization reclaims supply to petrol pump 1 current value of running before starting at the judgement gasoline vapour and when above, stops the driving of petrol pump 1 for regulation.That is, gasoline vapor recovery apparatus 100 is avoided moisture freezes action 1.In addition, in Fig. 2, illustrated the situation of utilizing pressure detector 70 to detect the value of the electric current of supplying with to petrol pump 1, but be not limited to this, also can be provided for detection and detect the value of the electric current of supplying with to petrol pump 1 to the current detector of the value of the electric current of petrol pump 1 supply.
In addition, also can be for example, by the stopping period (, the stopping period more than 1 day) of gasoline service station (specifically, being gasoline meter 101) as the judgment standard of avoiding moisture freezes action 1.That is,, if such as waiting gasoline service station is stopped for a long time in the winter time, it is high that the temperature that can be judged as refrigerating medium is reduced to the following possibility of prescribed limit.Therefore, controlling organization also can be according to the stopping period of gasoline service station, and the temperature of judging refrigerating medium 7 is reduced to below prescribed limit, and is avoided moisture freezes action 1.In addition, at the above-mentioned judgment standard of avoiding moisture freezes to move at 1 o'clock of beginning, also can suitably combine.
