The present invention relates to a kind of have be in heat in transmit connecting and can be along the primary side of circulation in the other direction and the multi-stage heat-exchanger assembly of primary side, wherein this primary side has the feed point that at least two streamwises stagger, and a valve system is set, and this valve system and the acting in conjunction of temperature sensor mechanism and control are by the heat transport fluid stream of primary side.
This multi-stage heat-exchanger assembly is for example open in DE 197 02 897 C2.Here the backflow of opening thermal source by a valve for the embolism of the water for industrial use on the primary side, thus the primary side of heat exchanger is by the flow of hot water mistake from thermal source.Beginning stream temperature according to the heat-carrying agent of primary side is controlled triple valve by temperature sensor.By means of this valve with the hot water-guiding of heat-carrying agent-normally by one or more pipeline section in the heat exchanger.Enlarge thus or dwindle effective heat-transfer area between primary side and the primary side.Also can regulate the capacity of heat exchanger according to the temperature on the primary side, this has obtained the temperature preset of the industrial water system on the primary side equally, or rather the hot length that shortens or prolong heat exchanger by the beginning stream temperature according to thermal source.Make that thus capacity of heat exchanger and current demand are suitable, and for the water for industrial use temperature and improving its stability.
But show that this system is more blunt.
Task of the present invention is to realize the stable regulation of primary side exit temperature.
This task so solves under the situation of the multi-stage heat-exchanger assembly of the described type of beginning, and valve system has the valve of oneself for each feed point.
Use a plurality of valves-its can relative configurations ground less-allow to regulate quickly and better stability.Construct in addition that a plurality of valves-it can be that simple choke valve-ratio uses the triple valve cost cheaper in principle, triple valve has complicated structure.Use this new organization plan heat-carrying agent stream not only can be assigned to the primary side of heat exchanger device according to the form of triple valve, also can supply with heat transport fluid or rather for all feed points.For example can supply with heat transport fluid can only for a feed point that is positioned at the first feed point downstream of primary side thus for the low heat loss of primary side.Because corresponding valve is only regulated little through-current capacity, realized better stability, because little valve can be regulated simpler and more quickly.A kind of littler " effectively " heat exchanger is also arranged, and littler reinforcement is arranged thus.Regulate quicker and more stable thus.The heat transport fluid conductance can be drawn by whole primary side for the heat loss that the primary side exit is bigger.At last also can supply with heat transport fluid simultaneously, thereby realize that the additional heat of primary side loads for all feed points.The classification increase that this energy is supplied with has also realized a kind of more stable adjusting because Xia Chong and on be punched under the situation of combinations thereof scheme and minimized.
Temperature sensor mechanism preferably has at least one temperature sensor, and it detects the temperature of the fluid of primary side.Can control the inflow of the heat transport fluid of primary side thus according to the temperature of the fluid of primary side.
Temperature sensor mechanism preferably has the temperature sensor with the feed point respective numbers, and it is arranged on primary side.Thus better the detection of primary side to the temperature effect of primary side.
When the temperature on the detection primary side in the feed point zone of temperature sensor on primary side is particularly suitable.Can detect effect thus better by the heat transport fluid of each the feed point input on the primary side.Realized much accurate adjusting thus.
At the corresponding valve of this preferred especially each temperature sensor.Just the quantity of temperature sensor is corresponding with the quantity of valve.For example each valve can be controlled by the temperature sensor under it.Where necessary, when observing specific grade, be favourable.A kind of possible method of operating is, at first only the valve supplied with of the feed point that be in downstream of operation on primary side.Have only this valve of working as to open fully, and temperature not enough, just opens a valve, this valve is supplied with to the feed point that is positioned at its upstream.Obtain a kind of method of operating of classification in this way, it can produce desired temperatures in primary side faster.
In a kind of alternative organization plan, temperature sensor is connected with a common controlling organization, this controlling organization control valve.Controlling organization can obtain heat demand from all temperature informations then, can realize that then the another kind of heat transport fluid on primary side distributes, so that obtain the water for industrial use temperature of expectation in the exit of primary side.
Preferably at least one is combined with valve and differential pressure regulator that the feed point that is arranged in the first feed point downstream along flow direction is connected, and this differential pressure regulator keeps constant compression force by valve.By means of this organization plan, heat transport fluid by the supply of valve and thus on the principle heat only depend on the opening degree of this valve by the supply of this valve.This has significantly simplified adjusting.
Describe the present invention in conjunction with the accompanying drawings in detail according to preferred embodiment below.
Accompanying drawing illustrates:
Fig. 1 shows a kind of first organization plan of multi-stage heat-exchanger assembly;
Fig. 2 shows a kind of second organization plan of heat exchanger device;
Fig. 3 shows a kind of the 3rd organization plan of heat exchanger device.
Fig. 1 shows heat exchanger device 1, and it has a heat exchanger 2, and this heat exchanger has a primary side 3 and a primary side 4.Primary side 3 and primary side 4 are only schematically illustrated at this.During they are in each other and conduct heat connect, thereby can be transferred to one other fluid, for example water for industrial use on the primary side 4 by the heat that heat transport fluid is transported to primary side 3.As by shown in the arrow, flow through primary side (in the view of Fig. 1: from right to left), and flow through primary side 4 along opposite direction along first direction.Water for industrial use is imported primary side 4 by inlet 5, and receives at outlet 6 places., and 8 receive to primary side input heat transport fluid, for example from the hot water of district heating equipment by beginning stream 7 by refluxing.
Beginning stream 7 is divided into two branch lines 9,10, and wherein first branch line 9 is connected with first feed point 11 of primary side 3, and second branch line 10 is connected with second feed point 12 of primary side 3.Second feed point 12 is with respect to the through-flow downstream that is positioned at first feed point 11 of primary side 3.That is to say that the heat transport fluid of supplying with first feed point 11 flows through the whole primary side 3 of heat exchanger 2.Supply to the part that heat transport fluid in the primary side 3 only flows through the primary side 3 of heat exchanger at second feed point 12, that is to say first section 13 of primary side 3 and can't help to be used for heat transmission in the heat transport fluid of second feed point, 12 inputs.
Corresponding therewith, primary side 4 also has two portion's sections 14,15, and its middle part 14 always is used for heat is delivered to primary side 4 (perhaps opposite) from primary side 3, and portion's section 15 has only when heat transport fluid and just uses during by branch line 9 input first feed point 11.
In first branch line 9, be provided with first valve 16, and in second branch line 10, be provided with second valve 17.Two valves are in the inflow of feed point 11, the 12 control heat transport fluids that connect separately to primary side 3.When first valve 16 is opened, then supply with heat transport fluid to first feed point 11, these heat transport fluids flow through whole primary side 3 then.When second valve 17 is opened, on second feed point 12, import heat transport fluid, thereby only on second section 14, heat is delivered to primary side 4.Can certainly open two valves 16,17, thereby only some heat transport fluid flows through portion's section 13, and the remainder of primary side 3 is supplied with relatively large heat transport fluid.
For control valve 16,17, be provided with first temperature sensor 18, it is arranged in the scope of first feed point 11, and is provided with second temperature sensor 19, and it is arranged in the scope of second feed point 12.Two temperature that temperature sensor 18,19 detects on the primary side 4.

When will when outlet 6 places obtain to have the water for industrial use of desired temperatures, opening the valve that does not specifically illustrate there.The temperature of water for industrial use that flows through primary side 4 is too low, but its absolute value is not constant, but affected by environment.As long as the temperature that exists in primary side does not also meet given rated temperature, so just detect by second temperature sensor 19, this second temperature sensor is transferred big (aufsteuern) second valve 17, thereby water for industrial use is heated in primary side 4.Enough water for industrial use is heated to desired temperatures in heat is delivered in the level of the portion's section 14 with primary side 4 of heat exchanger 2, that has not just needed other measure.In this case, just first temperature sensor 18 also determines to have reached rated temperature.The adjusting of water temperature is carried out so far, just only by the interaction between second temperature sensor 19 and second valve 17.This adjusting can realize faster, and is very little thereby the danger of starting of oscillation also keeps.
Even first temperature sensor 18 also determines also not reach rated temperature, first temperature sensor 18 is transferred big first valve 16 then, thereby heat additionally can be delivered on portion's section 15 of primary side 4 from primary side 3.
The opening and closing that is to say two valves 16,17 are by 18,19 controls of two temperature sensors.The point of adjustment of valve 16,17 can be controlled by valve control device.Valve control device can be configured to multiple different form.For example valve 16 can cut out and valve 17 is opened, thereby the heat transmission is only carried out in portion's section 14 of primary side 4.Also driver's valve 16,17 like this makes valve 16 open, and valve 17 cuts out.In this case, heat is delivered in portion's section 14 and 15 on the primary side 4 and carries out.Also can open two valves 16,17.Heat is delivered on portion's section 15 of primary side 4 and carries out in this case, and the heat transmission that enlarges on portion's section 14 of primary side 4.
As shown in the figure, valve 16,17 can directly be driven by temperature sensor 18,19, for example by electronic, magnetic force or mechanical trigger mechanism.Also can use can manually operated valve 16,17, and this valve must trigger with the temperature of hand according to sensing or measurement then.
Fig. 2 shows a kind of alternative structure scheme of heat exchanger device, and wherein components identical is provided with identical Reference numeral.
Here the variation of being done is, temperature sensor 18,19 no longer directly with valve 16,17 couplings connection, but join with same controlling organization 20 couplings that trigger valve 16,17.Can also pay close attention to of the influence of the temperature of primary side 3 better by means of this controlling organization 20 to primary side 4.
Fig. 3 shows the another kind of embodiment of multi-stage heat-exchanger assembly, and wherein components identical is provided with the Reference numeral identical with Fig. 1 and 2.
Each valve 16,17 has a driving mechanism 21,22, and wherein driving mechanism 21,22 is by temperature sensor 18,19 controls.
Arranged a pressure-control valve 23 with 17 one-tenth one on second valve row ground, its by diaphragm 24 and capillary 25 before by valve 17 supply pressure and the diaphragm spring 26 that just schematically shows control.Valve 23 is used for by valve 17 pressure being fallen and keeps constant.
16 Temperature Influence that are subjected on the temperature sensor 18 of first valve.Just the opening degree of valve 16 is according to the adjustment in the exit of primary side 4.Second valve 17 is regulated according to the pressure of beginning stream 7, because pressure reduction keeps constant by second valve 17 by means of differential pressure regulator, wherein differential pressure regulator has pressure-control valve 23.
