The preferred plan that carries out an invention
Gasoline of the present invention reclaims main three the operations recovery gasoline that adopt.Fig. 1 is the schema of expression gasoline recovery process.
Among Fig. 1, at first, when gasoline service station adds gasoline to automobile, because the bottom of pneumatic thickener exists the gasoline of liquid, the top of pneumatic thickener to have saturated gasification gasoline, thus the operation of suction, promptly when refueling, suction is present in the gasification gasoline in the pneumatic thickener, deliver in the gasoline recovery plant, the pressure in the retrieving arrangement is risen, make gasification gasoline form the state (step (following is " S1 ")) of easy condensation.
Then, the gasification gasoline that is drawn onto in the gasoline recovery plant is liquefied at the retrieving arrangement internal recycle, particularly, by making heat-eliminating medium and gasification gasoline in the gasoline recovery plant carry out heat exchange cool gasification gasoline, with the gasoline of condensation/liquefaction with after the gasification gasoline of gas separates, the gasification gasoline of gas repeats to make it the refrigerative operation with the heat-eliminating medium heat exchange again, and the gasification gasoline that reclaims becomes the condensation operation (S2) of liquid gasoline.
Then, the circulation of the gasification gasoline in the gasoline recovery plant is stopped, the gasoline that liquefies is discharged to the discharge operation (S3) in the gasoline withdrawing can.
Below, according to Fig. 2, the formation of the gasoline recovery plant in the embodiment 1 is described.
Among Fig. 2, gasoline recovery plant mainly is made of heat source unit 1 and cycling element 2.In addition, heat source unit 1 has pipe arrangement to connect the 1st loop line of compressor 3 and condenser 4, throttling set 5, vaporizer 6, is connected the groove 7 that holds vaporizer 6 and the 2nd loop line of pump 8 and gasoline condenser 9 with pipe arrangement.In addition, in the 1st loop line flow of refrigerant is arranged,, can use do not have flammable HFC cooling agent (for example R404A, R410A, R407C etc.) or natural cooling agent (CO for example as this cooling agent
2Deng).In addition, deicing fluid (for example, salt solution (ethylene glycol)) circulation is arranged in the 2nd loop line.Moreover, when making the gasification gasoline condensation more than 0 ℃, also can make water.
Below, the action in the heat source unit 1 is described.The gas refrigerant of the high temp/high pressure of compressor 3 compressions is emitted heat at condenser 4 becomes liquid state.The cooling agent that becomes liquid state reduces pressure at throttling set 5 and becomes the gas-liquid two-phase cooling agent of low temperature/low pressure, inflow evaporator 6.In vaporizer 6, absorb heat the salt solution of gas-liquid two-phase cooling agent in groove 7, become gas refrigerant, sucked by compressor 3.Moreover, the flow direction of 17 expression cooling agent.
In addition, the salt solution in the groove 7 is cooled by the cooling agent that heat is supplied with in the vaporizer 6, and this refrigerative salt solution is sent to gasoline condenser 9 through pump 8.In addition, the salt solution in the gasoline condenser 9 carries out heat exchange with the gasification gasoline that is present in the gasification gasoline condensing container 12, absorbs heat and the temperature rising from gasification gasoline.Then, this salt solution is cooled in pump 8 is delivered to groove 7 again.18 expression brinish flow directions.
Below, the action in the cycling element 2 is described.
At first, open the 1st switch-valve 13, reclaim with hose connection upstream side from gasification gasoline and suck gasification gasoline, be stored in the container 11.Moreover this moment, the 3rd switch-valve 15 cut out, and the 2nd switch-valve 14 is closing conditions.Then, when the suction of gasification gasoline finished, control device 16 cut out the 1st switch-valve 13, opens the 2nd switch-valve 14, close the 3rd switch-valve 15 after, start recycle pump 10, make gasification gasoline at cycling element 2 internal recycle.The flow direction of 19 expression gasification gasolines.In this circulation, by behind the container 11, deliver in the gasification gasoline condensing container 12 from recycle pump 10 effusive gasification gasolines, gasification gasoline condensing container 12 in and the salt solution in the gasoline condenser 9 carry out heat exchange and be cooled, a part liquefies.The gasoline storage of liquefaction is in the bottom of gasification gasoline condensing container 12.And uncondensable gasification gasoline by the 2nd switch-valve 14, be recycled pump 10 and suck after, deliver to again and make it cooling in the gasification gasoline condenser 12.Moreover by carrying out this circulation, the concentration of gasification gasoline reduces in time.
Then, control device 16 is opened the 3rd switch-valve 15 through after the specified time running of recycle pump 10 being stopped.So the gasoline that is liquefied, is stored in the bottom by gasification gasoline condensing container 12 utilizes liquid head to be discharged in the gasoline withdrawing can.
By circulating in this wise, the gasification gasoline liquefiable is reclaimed as gasoline.
Below, to utilizing recycle pump 10 gasification gasoline is described in the reason of loop line internal recycle.If make the gasification gasoline circulation, then because long or guaranteed gas flow rate to a certain degree with the duration of contact of gasoline condenser 9 in the gasification gasoline condensing container 12, so can make heat transfer rate does not improve significantly than not making gasification gasoline round-robin occasion, can reduce recovery time, efficient is very good.
Fig. 3 is the graphic representation of analog result of the gasoline recyclability of expression gasoline recovery plant shown in Figure 2.Among Fig. 3, X-coordinate represents that brinish temperature, ordinate zou represent the gasoline rate of recovery (amount of gasoline (g) of the amount of gasoline of liquefaction (g)/recovery), and as seen from Figure 3, the brinish temperature is low more, and then the rate of recovery of gasoline rises more.This is that then the more little cause of the partial vapor pressure of gasoline for example, is about-10 ℃ by making the brinish temperature, the recyclable so far about gasoline more than 90% that is discharged in the atmosphere because brine temp is low more.
Like this, utilize recycle pump 10 to make the gasification gasoline circulation,, can cut down recovery time significantly by liquefaction in gasoline condenser 9.
In addition, use the steam compression type freezing cycle device by heat source machine, can be expeditiously and obtain about-10 ℃ temperature band easily, change that also can follow load simultaneously.
In addition, as the cooling agent of heat source unit 1,,, also can guarantee the security of the gasoline service station that No Open Flames simultaneously so can reduce load to environment owing to use no flammable HFC cooling agent or natural cooling agent.
In addition, the flow direction of gasification gasoline is to flow to the top from the below of gasoline condensing container 12 among Fig. 2, but also can be that appearance as Fig. 4 flows to the below from the top.If flow in this wise, then the gasoline of condensation liquefaction successfully flows to the below, and the efficient of gasification gasoline condensation increases, and the gas-liquid separation efficient of gasoline condensing container 12 also rises thereupon.
Fig. 5 is the pie graph of gasoline recovery plant in the expression embodiment 2, is the figure that establishes pressure detection means 20 between the gasification vapour phase condensing container 12 of the cycling element 2 of the gasoline recovery plant that Fig. 2 represents and the 3rd switch-valve 15.In addition, among Fig. 5,, use identical symbol, save its explanation identical formation with Fig. 2 or equal formation.
Fig. 6 is analog result is carried out in expression to pressure in the cycling element 2 and gasoline rate of recovery relation a graphic representation.Moreover among Fig. 6, X-coordinate represents that pressure, the ordinate zou in the cycling element represent the gasoline rate of recovery (amount of gasoline (g) of the amount of gasoline of liquefaction (g)/recovery).And the pressure in the cycling element 2 changes by the volume that changes in the cycling element 2.In this Fig. 6, for example, (about 1kgf/cm under the normal atmosphere
2When gasification gasoline 70 (liter) absolute pressure) seals among the cycling element of volume 35 (liter), because volume becomes half, so cycling element 2 interior pressure are 2 (kgf/cm
2Absolute pressure).
As seen from Figure 6, the pressure of cycling element 2 is high more, and then the gasoline rate of recovery has the tendency of rising more.Therefore, if utilize recycle pump 10 that gasification gasoline is sent in the cycling element to improve the pressure in the cycling element 2 as far as possible, then the rate of recovery of gasoline increases.
Yet during the gasification gasoline pressurization, kindling temperature reduces, because its dangerous increase, so the pressure of fire service law regulation gasification gasoline is below 0.2MPa.Therefore, pressure detection means 20 are set in the present embodiment, carry out the control of pressure suppression at 0.2MPa.
Particularly, at first, the 1st switch-valve 13 in opened condition, the 2nd switch-valve 14 is that closing condition, the 3rd switch-valve 15 are closing condition, and gasification gasoline is delivered in the cycling element 2 by recycle pump 10, pressure in the cycling element rises at leisure, reaches the 1st specified pressure (0.2MPa is following) at last.When control device 16 confirms that the value of pressure detection means 20 detections surpasses the 1st prescribed value, make the 1st switch-valve 13 become off status by the state of opening, make the 2nd switch-valve 14 become out state by closing shape, the 3rd switch-valve 15 still is an off status, starts recycle pump 10 and makes gasification gasoline at cycling element 2 internal recycle.By trip switch valve in this wise, gasification gasoline is circulated below specified pressure, reclaim.
Fig. 7 is the pie graph of gasoline recovery plant in the expression embodiment 3, is to establish the figure that the pressure that detects according to pressure detection means 20 is judged the calculation apparatus 21 of the saturated usefulness of pressure in the cycling element 2 of gasoline recovery plant shown in Figure 5.In addition, in Fig. 7, identical formation with Fig. 5 or equal formation are used identical symbol, save explanation.
Below, gasoline being reclaimed the determination methods that finishes describe, Fig. 8 is the graphic representation of expression runtime and gasoline yield relation, Fig. 9 is the graphic representation of the pressure dependence in expression runtime and the cycling element 2.Approximately running is in the time of 3 minutes among Fig. 8, and the gasoline yield is saturated, and approximately running is in the time of 3 minutes among Fig. 9, and the pressure in the cycling element 2 is also saturated, illustrates that thus there is correlationship in pressure and the gasoline yield in the cycling element 2.
Therefore, the pressure that applying pressure detection means 20 detects in the cycling element 2 if pressure does not change, then can be judged to reclaim and finish.
Based on this viewpoint, promptly the flowchart text according to the action in Fig. 1 condensation operation, Figure 10 carries out the method that gasoline reclaims.
At first, make the 1st switch-valve 13 be off status, the 2nd switch-valve 14 is out the state that state, the 3rd switch-valve 15 are the pass, starts recycle pump 10 (S10).
Then, the pressure P (t) under the time t that applying pressure detection means 20 detects in the cycling element 2 is stored into (S11) in the calculation apparatus 21.Then, wait for the scheduled time: T second (S12), detect the pressure P (t+T) of cycling element under 2 interior times (t+T) (S13), use calculation apparatus 21 to carry out the calculation (S14) of Δ P=P (t)-P (t+T).Then, control device 16 judges that whether this Δ P is than the 2nd prescribed value ε little (S15).This S15 judges the Δ P occasion littler than ε, can judge that pressure is saturated, and control device 16 stops the running (S16) of recycle pump 10.And S15 judges the occasion little unlike ε, returns S11.
By carrying out such control, not only can reclaim gasoline expeditiously, and can guarantee security fully.
Gasification gasoline in the pneumatic thickener was considered as user's belongings originally, so must consider and the gasoline of the gasoline that reclaims with amount, or return the amount of money that the gasoline with recovery offsets, this occasion shown in the schema of Figure 11, must have the survey yield operation (S4) of measuring the amount of gasoline that reclaims after S3.
Figure 12 is the pie graph of the gasoline recovery plant of expression the present embodiment 4, is in the gasoline recovery plant of Fig. 7, establishes the figure of the under meter 22 of measuring the gasoline yield at the Way out (gasoline withdrawing can side) of the 3rd switch-valve 15.
By constituting in this wise, can measure from gasification gasoline condenser 12 and be discharged to gasoline flow in the gasoline withdrawing can, can deduct the gasoline that is equivalent to reclaim part the amount of money or append gasoline.
In addition, can certainly establish the weight meter and replace under meter 22, measure the weight of the gasoline that reclaims.
In addition, computer is linked to each other with this under meter 22, the flow of measuring according under meter 22 automatically calculates the return amount of money, can also link with the gasoline oiling machine, appends and the corresponding vapour phase of measuring automatically of flow.
Figure 13 is the figure that gasoline recovery plant constitutes in the expression embodiment 5.This gasoline recovery plant does not use the brine refrigeration gasification gasoline, but adopts the mode of directly using cooling agent cool gasification gasoline.
Among Figure 13, heat source unit 1 has the loop line of using pipe arrangement to connect compressor 3 and condenser 4, throttling set 5 and gasoline condenser 9, uses HFC cooling agent (for example R404A, R410A, R407 etc.) or natural cooling agent (CO for example as cooling agent
2Deng).Cycling element 2 uses pipe arrangement to connect recycle pump 10 and container 11, gasification gasoline condensing container the 12, the 1st switch-valve the 13, the 2nd switch-valve 14 and the 3rd switch-valve 15.In addition, use the switch motion of running, the 1st switch-valve 13 and the 2nd switch-valve 14 and the 3rd switch-valve 15 of control device 16 Control Circulation pumps 10.
The control of this cycling element 2 or action are identical with the described state of Fig. 2.
In the heat source unit 1, the high temperature of compressor 3 compression, the highly compressed gas refrigerant is emitted heat at condenser 4 becomes liquid state, becomes the gas-liquid two-phase cooling agent of low temperature, low pressure then through throttling set 5 decompressions, flows in the gasoline condenser 9.In gasoline condenser 9, this gas-liquid two-phase cooling agent absorbs heat from the gasification gasoline of gasification gasoline condensing container 12, become gas refrigerant, is sucked by compressor 3.And the gasification gasoline of gasification gasoline condensing container 12 loses heat, carries out condensation, liquefaction.
