As shown in Figure 2, nitrogen filled-type expansion pressue device of the present invention comprises cycle cooling plating drum 10, expansion pressurized tank 230, nitrogen supply (NS) assembly 250 and replenishes tank 330.
As described in the background technology, above-mentioned cycle cooling plating drum 10 comprises heat resource equipment 1 substantially and meets (cooling heating equipment) 10a.
Heat resource equipment 1 is to concentrate for the district cooling heating to be arranged in a city or the certain zone, and be supplied to each electricity consumption facility or to the device of each existing zone duct net supply heat, roughly comprise waste-heat power generation factory, incinerate the heat exchanger of factory or large-scale cooling heating installation etc. on a large scale.
Be passed to the heat exchanger compartment of each electricity consumption facility by cycle cooling plating drum 10 through the heating agent of above-mentioned heat resource equipment 1 heating, and the heating agent that is transmitted is passed to as the load 10a of each layer electricity consumption facility cooling heating equipment of apartment or building and finishes after the cooling heating, is recycled to heat resource equipment 1 by cycle cooling plating drum 10 again.
In the cycle cooling plating drum 10 of the cooling heating system of said structure, also preferentially possesses the heat storage tank 10b that is used to accumulate the heat that heat resource equipment 1 produced, and this moment, each possesses transfer pump 10c in the inflow side to load 10a, possesses reflux pump 10d in the inflow side of heat source equipment 1.
As shown in Figure 2, above-mentioned heat storage tank 10b is arranged in parallel in cycle cooling plating drum 10, and is used to be provided with the bifurcated pipe of cycle cooling plating drum 10 and heat storage tank 10 in the prior art, can respectively be provided for opening and closing the motor-driven valve of each pipeline as required.Can utilize above-mentioned heat storage tank 10b, transfer pump 10c, reflux pump 10d and motor-driven valve, be combined into various operational modes.
For example, first, under the bigger situation of load, can be by closing the motor-driven valve of the bifurcated pipe side that connects heat storage tank 10b, so that pipeline water is along maximum on the whole closed cycle, thereby make heat resource equipment 1 directly carry out work to load 10a; The second, under do not load 10a or few situation of loading, by open whole motor-driven valves, thereby when making heat resource equipment 1 directly carry out work to load 10a, 10b accumulates heat by heat storage tank; In addition, but stop supplies pump 10c also only moves reflux pump 10d, finishing regenerative operation, or only with heat storage tank 10b to the load 10a operation of dispelling the heat.
In addition, cycle cooling plating drum 10 of the present invention preferentially uses variable flow system (VWV:Variable Water Volume System).Variable flow system is meant the rotation number (inverter control) of utilizing variable speed electric motors, particularly to change to be used to the pump of transferring pipeline water in pipe-line system, with the system of adjusting pump discharge (discharge-amount).In cycle cooling plating drum 10, if the heat that heat resource equipment 1 is produced is big, then the outlet temperature because of heat resource equipment uprises, and increases circular flow thereby quicken reflux pump 10d, so that outlet temperature is maintained within the effective temperature scope.In contrast, under the little situation of heat that heat resource equipment 1 is produced, if keep high flow capacity, then, outlet temperature can not reach the effective temperature that to accumulate to load side or heat storage tank 10b because of reducing, therefore reduce the flow of reflux pump 10d, so that outlet temperature is maintained within the effective supply temperature range.
That is, in the present invention, preferentially heat or the temperature (utilizing calorimeter or temperature sensor) that is produced by real-time detection heat resource equipment 1 changes control reflux pump 10d rotation number according to it, thereby at the heat that is produced after a little while, reduces reflux pump 10d flow.In addition, cycle cooling plating drum 10 load 10a or load 10a are not few having, that is, and and under the few situation of thermal losses, because of need not to the many pipeline water of load 10a side supply, the preferential temperature of passing through to detect by the pipeline water of backflow after the load 10a changes the rotation number of control transfer pump 10c according to it, thereby higher in the temperature of pipeline water, promptly, thermal losses during by load 10a reduces the pump discharge of transfer pump 10c after a little while, to reduce the flow of offered load 10a.
If adopt above-mentioned variable flow system, then can prevent unnecessary energy waste by the rotation number of regulating pump.In addition, as expansion pressue device of the present invention in, even utilize the rotation number of saving the variable flow system adjusting pump of energy according to the volume change of heat resource equipment 1 and load 10a, with change spue pressure and circular flow, also can utilize expansion pressurized tank between transfer pump 10c and reflux pump 10d to keep the pressure of certain limit, so that pipe-line system is kept pressure stable, thereby guarantee the stability and the reliability of cycle cooling plating drum.

As mentioned above, the present invention pressurized tank 230 usefulness nitrogen (N that expand
2) as blanketing gas, and be the supply of above-mentioned nitrogen, connect nitrogen supply (NS) assembly 250 in above-mentioned expansion pressurized tank 230, and in order to regulate with the inflow of swelling water and expansion pressurized tank 230 internal pressures that reflux and change, above-mentioned expansion pressurized tank 230 possesses the various valves of the supply that is used for nitrogen and exhaust and is used to detect the various sensors of expansion pressurized tank 230 internal pressures and numerical digit.
Particularly, and for example shown in Figure 2, the present invention's pressurized tank 230 that expands, comprising: pressure sensor PT1 is used to detect expansion pressurized tank 230 internal pressures; Level sensor LT1 is used to detect the water level of swelling waters in the expansion pressurized tank 230; Filling-valve S1 is used for from above-mentioned nitrogen supply (NS) assembly 250 to expansion pressurized tank 230 inner the supply of nitrogen; Air bleeding valve S2 is expelled to the outside with expansion pressurized tank 230 inner nitrogen; Safety valve when being used for pressure in the groove and rising suddenly, prevents the blast of groove etc. by automatic vent etc.
In the early stage, expansion pressurized tank 230 obtains nitrogen supply (NS) and be filled to first pressing from nitrogen supply (NS) assembly 250, and water level is in ultralow water level according to the open filling-valve S1 of the control of controller (not shown).If pipeline water expands, then pipeline water flows into expansion pressurized tank 230 inside from cycle cooling plating drum 10, and the water level of expansion pressurized tank 230 rises to peak level and detected by level sensor LT1, and detected by pressure sensor PT1 with expansion pressurized tank 230 pressure inside that the inflow of swelling water is risen, thereby when water level and pressure arrive default certain value, detection signal according to above-mentioned pressure sensor PT1 and level sensor PT2, discharge nitrogen by controller (not shown) open row air valve S2, maintain within the safe allowed band with internal pressure with expansion pressurized tank 230.
If because of swelling water is back to cycle cooling plating drum 10 or the few part of passing in time is nitrogen gas dissolved in water again, the pressure of expansion pressurized tank 230 is reduced to below the operating pressure, then will detect pressure that reduces and the water level that detects reduction by level sensor LT1 by pressure sensor PT1, and according to the open filling-valve S1 of above-mentioned detection signal, thereby again to the expansion pressurized tank 230 inner nitrogen of filling, to keep the suitable operating pressure of expansion pressurized tank 230.In the pipe of filling nitrogen, preferentially possesses the check-valves that prevents that nitrogen from flowing backwards.
In addition, if when discharging nitrogen, only use single air bleeding valve, when then any one in pressure sensor PT1, level sensor LT1, controller, air bleeding valve S2 breaks down, because of expansion pressurized tank 230 is connected serially to high-pressure system, exhaust will be proceeded and moment is reduced to below the normal pressure (with the saturated vapor pressure of temperature) pressure, thereby cause the state that can't work that is in of extensive cooling heating system.
For preventing above-mentioned situation, as double security device, in gas extraction system, in expansion pressurized tank 230 water level switch LS1 is set, it detects whether to arrive specific water level by the ON-OFF contact point mode, can when having a power failure, use and failure-frequency low, and preferentially connect and stop very much valve S3 at the exhaust end of air bleeding valve S2, it is in open state at ordinary times all the time, and when above-mentioned water level switch detects water level in the groove and surpasses ordinary water level, closes according to the detection of water level switch LS1.That is, even air bleeding valve S2 continues to discharge nitrogen, the swelling water water level fat pressurized tank 230 inside rises to more than the default suitable water level, and then priming level switch LS1 closes and stops very much valve S3, to prevent the excessive discharge of nitrogen, guarantees the stable of system.
In the present invention, above-mentioned expansion pressurized tank 230 is similar with the expansion slot that is used for prior art cooling heating system on function, but it is different with prior art cooling heating system, it does not possess pressure relief assembly and is series at cycle cooling plating drum 10, therefore, when causing pipeline water to shrink because of the operating pressure of expansion pressurized tank 230 is very high, need not other pressue device, expansion pressue device 230 self can be finished pressurization, and this is maximum difference.In addition, be respectively arranged with expansion tube and return duct on the prior art cooling heating installation, but in the present invention, only connect cycle cooling plating drum 10 and expansion relief groove 230, and this be another characteristics by an expansion capstan 200.
In addition, the cooling heating system comprises the air of a large amount of oxygen with general filling in the expansion slot, but under the situation of using air, is dissolved in the swelling water that flows in the expansion slot because of oxygen, thereby causes Corrosion of Pipeline.Therefore, in the present invention,, will not comprise the nitrogen of oxygen as blanketing gas for preventing corrosive pipeline.Above-mentioned nitrogen supply (NS) assembly 250 is used for pressurized tank 230 the supply of nitrogen that expand to the present invention.
Nitrogen supply (NS) assembly 250 can be the nitrogen gas cylinder of filling a certain amount of nitrogen and carrying out exhaust in expansion pressurized tank 230, it can preserve high-purity nitrogen, and can detect expansion pressurized tank 230 pressure inside by pressure sensor.In addition, also can be when above-mentioned pipeline water expands, the nitrogen in the expansion pressurized tank 230 is directed to trough and compresses the method for using again.But in this case, complicated because of its device, need to continue to change the nitrogen gas cylinder and need to use a large amount of nitrogen, thus the running cost height therefore, consider from the economy aspect, preferentially with nitrogen gas generator 255 as above-mentioned nitrogen supply (NS) assembly 250.
Fig. 5 is the concrete structure figure of nitrogen supply (NS) assembly 250 of the present invention.As shown in Figure 5, at first, utilize air compressor 251 that the air in the atmosphere is compressed to certain pressure and supplies it; Then, be contained in dust in air or foreign matter etc. with air cleaner 252 bag filters; Afterwards, the dry air through air dryer 253 is supplied to separator 254.In separator 254, will separate and remove and be contained in airborne oil gas (OIL VAPOUR).Remove the nitrogen gas generator 255 of the dry air supply of impurity through said process, and will utilize this nitrogen gas generator 255 to generate high-purity nitrogen.The nitrogen that is generated is stored in nitrogen bath 259 after dashpot 256 utilizes oxygen-nitrogen analyzer 257 to calculate oxygen content and removes yang-energy.The nitrogen of being preserved is according to the detection signal of pressure sensor PT1 and level sensor LT1, and the control by controller is supplied to expansion pressurized tank 230.
From nitrogen bath 259 during to expansion pressurized tank 230 the supply of nitrogen, as high compression swelling pressurized tank of the present invention 230 systems in, need with higher pressure compressed nitrogen, could be to the expansion pressurized tank 230 inner nitrogen of filling.Therefore, in the present invention, between nitrogen gas generator 255 and nitrogen, also comprise nitrogen compressor reducer 258, compress paramount pressure, thereby can smoothly nitrogen be filled to high compression swelling pressurized tank 230 inside with the nitrogen that will finally generate.
Pass through said structure, in the rising of the pipeline water Yin Wendu of cycle cooling plating drum 10 and when expanding, swelling water flows into expansion pressurized tank 230, and when pipeline water shrinks, again be back to cycle cooling plating drum 10, and because of expansion pressurized tank 230 high-voltage operations, thereby need not other pressue device, swelling water self is forced into cycle cooling plating drum 10 and refluxes.
In addition, if the system temperature of cycle cooling plating drum 10 rises and cause pipeline water to expand, then water level rising and the nitrogen because of expansion pressurized tank 230 is compressed, thereby system pressure is risen.At this moment, under certain level, allow certain pressure to rise, but, then will stop pressure to rise by discharging nitrogen if rise to more than it.But if even discharging nitrogen so also continues to expand, then water level will continue to rise, and can't continue to accommodate swelling water until expansion pressurized tank 230, thereby have the danger that may cause the groove blast.Therefore, for preventing this type of danger, in nitrogen filled-type expansion pressue device of the present invention, also be provided with from the relief pipe 300 of above-mentioned expansion capstan 200 forks, it is used to discharge the superfluous swelling water of the capacity of accommodating above expansion pressurized tank 230, and preferentially possesses pressure loading valve assembly 310 at this.
As shown in Figure 2, above-mentioned pressure-reducing valve assembly 310 comprises pressure-reducing valve, it is arranged at from the relief pipe 300 of expansion capstan 200 fork and is used for discharging automatically swelling water more than the certain pressure, and comprises that preferentially pressure of motor-driven valve 310a, mechanical type in parallel keeps valve 310b and hand-operated valve 310c.
Pressure of above-mentioned mechanical type is kept valve 310b when the pressure of valve primary side is higher than setting pressure, fluid is expelled to the valve secondary side, thereby the pressure of valve primary side is maintained below the certain pressure, apply power by pilot-actuated valve, spring, dividing plate to valve disc, and when the pressure of valve primary side is higher than certain pressure, open valve disc and make fluid flow out to the valve secondary side, and when primary side pressure reduces, close.
Said electric valve 310a is preferential to be kept valve 310b with pressure of above-mentioned mechanical type and keeps certain pressure differential in parallel, replenishing mutually, thus even also can stable operation when power failure.Promptly, when normal operation, the motor-driven valve 310a that moves in electronic mode and mechanically a pressure of operation keep valve 310b and together move, but under the situation that supply of electric power is interrupted, even the outage of motor-driven valve 310a, also can keep the operation of valve by a pressure of mechanically operation, under situation about having a power failure, stably discharge superfluous swelling water.The force value signal that said electric valve 310a detects according to the pressure sensor PT3 that is arranged at relief pipe 300, open during pressure more than detecting default pressure by the control of controller, to discharge superfluous swelling water.
As shown in Figure 2, above-mentioned pressure-reducing valve assembly 310 also comprises hand-operated valve 310c.Normal operation keeps valve 310b by pressure and motor-driven valve 310a finishes, and above-mentioned hand-operated valve 310c, in trial run, check and very under the situation, manually open and close and use.
The superfluous swelling water of discharging by aforesaid pressure-reducing valve assembly 310 is stored in additional tank 330 temporarily, and when the contraction because of pipeline water causes relief pipe 300 (or expansion capstan 200) pressure to descend, by replenishing water pipe 400 with the superfluous swelling water water supply as a supplement of being preserved.As shown in the figure, make-up pump 410 and check-valves 420 are set on the above-mentioned additional water pipe 400, above-mentioned make-up pump 410 is according to passing through the detected force value signal of pressure sensor PT3, control by controller starts, thereby will be stored in the superfluous supplementing water of replenishing in the tank 330, be back to cycle cooling plating drum 10 by expansion capstan 200.At this moment, exhaust end at above-mentioned make-up pump 410, possess secondary pressure and keep valve 430, even thereby when utilizing the superfluous supplementing water of make-up pump 410 suction, to the certain pressure of 200 transmission of expansion capstan, to guarantee stability, in addition through decompression, by the inverter control of above-mentioned make-up pump 410, only supply required amount.
By said structure, the superfluous swelling water of discharging by relief pipe 300 is stored in temporarily and replenishes after the tank 330, and refluxing again when pipeline water shrinks is supplementing water, thereby when the excessive expansion of pipeline water, also can keep the stability of a system.
In addition, because of in above-mentioned additional tank 330, also may existing oxygen to be dissolved in dyshaemia and corrosive pipeline that supplementing water causes, thereby, preferentially fill low-pressure nitrogen for preventing above-mentioned phenomenon.For this reason, above-mentioned additional tank 330 is connected with nitrogen supply (NS) assembly 250, and in order to fill the nitrogen of the trickle pressure about 0.05kg/G, preferentially is equipped with pressure relief assembly 340 at the nitrogen supply (NS) pipe.Be the filling of the nitrogen of trickle pressure, two pressure-reducing valves of above-mentioned pressure relief assembly 340 preferential series connection are finished accurate step-down through twice.In addition, preferentially on above-mentioned additional tank 330, level sensor LT2 and pressure sensor PT2 are set respectively also, rise to setting value when above to rise to the above or water level of setting value in additional tank 330 internal pressures, by open electronic type air bleeding valve discharge nitrogen.
In addition, the end of above-mentioned relief pipe 300 is connected in and replenishes tank 330, and as shown in Figure 2, and is crooked downwards, so that at the lower side of the replenishing tank 330 superfluous swelling water that spues.If the accident on additional tank 330 of superfluous swelling water spues, then when the water level that replenishes tank 330 is low, in the process that superfluous swelling water is trickled down, might make the nitrogen gas dissolved of filling in swelling water.Therefore, nitrogen gas dissolved for preventing to greatest extent in the present invention in swelling water, thus the end of relief pipe 300 is arranged at the lower side of replenishing tank 330.In addition, the same with expansion pressurized tank 230, can possess anti-eddy current assemblies 240 in the bottom surface sections of above-mentioned additional tank 330.
Even above-mentioned additional tank 330 is set, but, the swelling water of too much pipeline water replenishes tank 330 if flowing into, then because of the gas compression not or the too much filling of inflow gas, will the overvoltage phenomenon take place at additional tank 330, therefore, nitrogen filled-type expansion pressue device of the present invention also preferentially comprises anti-overvoltage assembly 350.Fig. 6 is the concrete structure schematic diagram of above-mentioned anti-overvoltage assembly 350.Above-mentioned anti-overvoltage assembly 350 comprises U-shaped pipe 350a and overflow launder 350b.
Above-mentioned U-shaped pipe 350a is connected near the peak level MaxL1 that replenishes tank 330, when supplementing water surpasses above-mentioned peak level, to make the supplementing water overflow, in addition, even replenish the water level of tank 330 when low, also when internal gas pressure 0.05kg/G is above, discharge nitrogen.As shown in Figure 6, the end of above-mentioned U-shaped pipe 350a is connected in the peak level MaxL1 that replenishes tank 330, and be bent to form the U font downwards, and its terminal bottom surface sections that connects overflow launder 350b, be positioned at the position that is lower than drainpipe 350c or overflow pipe 350d, thereby not only discharge superfluous supplementing water, and after discharging superfluous Compressed Gas also supplementing water immediately, thereby prevent that extraneous gas from flowing into additional tank 330 inside, make to replenish the pressure that tank is kept 0.05kg/G.
Pass through said structure, above-mentioned U-shaped pipe 350a is in the water-filling state all the time, and as shown in Figure 6, is " h " because of being connected in the part water column that replenishes tank 330 sides among the U-shaped pipe 350a, therefore, the target of replenishing tank 330 is kept pressure 0.05kg/G and is equivalent to water column " h ".
In addition, the peak level MaxL2 of above-mentioned overflow launder 350b is lower than the peak level MaxL1 that replenishes tank 330, for this reason, water level switch LS2 is set, reach the situation of peak level MaxL2 with the water level that detects overflow launder 350b, and drainpipe 350c is arranged at the height of peak level MaxL2, carry out draining when above to rise to peak level MaxL2.
In addition, low water level sense switch LS3 is set, becomes the situation of low water level with detection, thereby when overflow launder 350b becomes low water level,, keep the suitable water level of overflow launder 350b from the supply of outside water treatment system 500 acquisition water.In addition, in above-mentioned water treatment system 500 pump 510 is set, and the said pump basis is replenished the detection signal of tank 330 level sensors, when the water that replenishes tank 330 was not enough, driving pump was to additional tank 330 supply water.
In addition,, also comprise at above-mentioned overflow launder 350b: blast pipe 350e, for gas in outside drain tank is in open state all the time; Overflow pipe 350d is used for discharging the water that surpasses peak level MaxL2 because of unexpected overflow to the outside.
As mentioned above, be connected in the pump of water treatment system 500 at ordinary times, according to the detection signal drives of the level sensor LT2 that replenishes tank 330 and supply water, begin water level A to the suitable water level between the water-filling stopping water level B thereby make water level maintain water-filling.At this moment, if because of the superfluous swelling water of relief pipe 300 discharges pass through in the expansion of the mistake of cycle cooling plating drum 10, then the water level that replenishes tank 330 will rise, and the pressure in the groove will become high pressure, and in order to remove above-mentioned high pressure, will be according to the detection signal open row air valve S4 of pressure sensor PT2, thus nitrogen sentenced, reduce pressure.
But above-mentioned air bleeding valve S4 has and may break down or produce excessive pressure suddenly because of excessive expansion.At this moment, will discharge supplementing water by U-shaped pipe 350a and produce overflow, but be equivalent to " h " highly pressure of water column, thereby only when the pressure of supplementing water is above above the pressure that is equivalent to " h ", overflow take place just because of in above-mentioned U-shaped pipe 350a, existing.For example, be 500mm if establish " h ", then Ci Shi pressure is 0.05kg/G.Therefore, only possesses 0.05kg/G with the supplementing water of upward pressure just a road or discharge superfluous nitrogen.According to such structure, even at additional tank 330 overvoltage takes place, also can be limited in below the 0.05kg/G, and if when surpassing 0.05kg/G, the water that replenishes tank 330 is by the 350a overflow of U-shaped pipe and flow into after the overflow launder 350b, the water of certain water level will be expelled to the outside, thereby guarantee the stable of system.
The nitrogen filled-type expansion pressue device of the present invention of said structure need not other pressue devices and swelling water can be back to cycle cooling plating drum 10, and also comprises pressure-reducing valve assembly 310, additional tank 330 and overflow launder 350b etc., thereby guarantees the stability of system.But, because of the present invention with nitrogen as the blanketing gas in the groove, thereby because of the high operating pressure of the expansion pressurized tank 230 of system, improve the solubility of nitrogen, thereby might become factor because of its dyshaemia.And for addressing the above problem, as shown in Figure 2, the present invention also preferentially comprises vacuum degasser 10e, and it takes out a part of pipeline water and be back to pipeline again after outgasing under vacuum state in cycle cooling plating drum 10, and because of destroying environment, should avoid using calculating more and wait medicine.In addition, also can preferentially assist circulating water treatment device (being used to handle the solids that swim such as earth) is set, to improve the water quality of recirculated water.
The foregoing description is only unrestricted in order to explanation the present invention, those of ordinary skill in the art is to be understood that, can make amendment, be out of shape the present invention or be equal to replacement, and not break away from the spirit and scope of the present invention, it all should be encompassed in the middle of the claim scope of the present invention.
