The present invention is a cleaning system and a servicing unit thereof, adopts spheroid to clear up the fluid conducting tube of condenser and other various heat exchangers.
The operating principle of the present invention being cleared up system and servicing unit thereof can obtain better understanding by following with reference to the accompanying drawing illustration.
Fig. 1 a-1c clears up system 10 at the sketch in different operating stage for the present invention, in order to cleaning condenser 12.Condenser 12 has fluid conducting tube 14, and cooling liquid as water, makes fluid (as steam or the cooling gas) condensation in the space between the condenser tubes 14 of flowing through through fluid conducting tube.Do the circulation pumping by 20 pairs of cooling fluids of pump in closed circuit, be positioned at entry conductor 22, the condenser tubes 14 that condenser 12 upstream side are connected with condenser 12 inlet header casees 16 and be positioned at condenser 12 downstreams and the delivery channel 24 that is connected with condenser 12 outlet header casees 18 closed circuit comprising.
In general, cleaning system 10 comprises three parts: a plurality of spheroids 26, in order to make forced circulation and to remove bacterium and the fouling that has produced via condenser tubes 14; Separator 28; With spheroid EGR 30.Separator 28 is between condenser 12 downstreams and spheroid EGR 30.Separator 28 is in order to tell spheroid 26 after spheroid 26 each process condenser tubes 14 from the fluid of circulation in system 10.Separator 28 is delivered to spheroid 26 in the spheroid EGR 30 by conduit 32.Spheroid EGR 30 is between in order to the separator 28 and condenser 12 upstream examples of accepting spheroid 26 from the spheroid EGR.Spheroid EGR 30 is in order to pass through the upstream side of conduit 34 with spheroid 26 directive condensers 12.
The characteristics that now just from separator 28 spheroid 26 are emptied completely and are sent to the 30 concrete decision design of adopting of spheroid spheroid EGR are described as follows.For obtaining the other improvement that separator 28 is adopted is then explained by Fig. 3 a-3q in addition following from sieving the condition that is emptied completely spheroid 26 58.At first, the outlet header case neck 18a of condenser tubes 14, inlet 46 are identical with the area of section that sieves 58 substantially, thereby make from condenser 12 and make substantially laminar flow stably by the fluid that separator 28 flows to delivery channel 24.Secondly, pressure reduction on the cross-section sieve wall plane is connect to the greatest extent as far as possible in zero, spheroid 26 is unlikely when mobile in sieve 58 zones to be pressed sieve 58 wall bodies and does freely to go in ring in sieving thereby make.This pressure reduction just can draw the sieve 58 perforate gross areas under at least about the situation that is five times in its area of section fully.But if the outlet header case neck 18a of condenser tubes 14, inlet 46 and sieve 58 area of section and inequality, then sieving the 58 perforate gross areas should be at least about being five times in the general area of section that is determining the condenser tubes 14 outlet header case neck 18a of flow.Must be pointed out that the total open area of sieve is defined as the gross area of sieve aperture.The 3rd, preferably spheroid outlet 50 is located at the center of sieve 58, produce the last one vortex strongly when leading pressure is following delivery channel 24 in so that the leading pressure spheroid conduit 32 in drops to, thereby make spheroid 26 whole emptyings from separator 28.
In general, spheroid EGR 30 has four parts.At first be in order to collect spheroid 26 in order to it is injected the gatherer 60 of entry conductor 22.Gatherer 60 with in order to the conduit 32 of accepting spheroid 26 from separator 28 be connected in order to conduit 34 spheroid 26 directive condensers 12 upstreams.Gatherer 60 preferably has enough storage volumes so that whole spheroid 26 enters circulation.Next is a tight tank 62, in order to storing the injecting fluid of a constant volume, leads 14 positive upstream so that will exist wherein spheroid 26 to take to pipe via emitting of gatherer 60 fluid.Jar 62 can fill with fluid by the discharge port of gatherer 60 or from independent fluid source (not shown), preferably has enough memory capacity so that will exist the whole spheroids in the gatherer 60 to inject in the main channel of fluid.The 3rd is compressor 64, emits the calibrated shot fluid in order to the air hose 66 feed compressed air by band valve 68 to improve jar 62 interior leading pressure.The 4th is pressure reducer 70, makes cleaning system 10 perform the preparation of spheroid 26 circulations next time in order to reduce jar 62 interior pressure.Pressure reducer 70 can be a valve or a pump.In general, pressure-reducing valve 70 is to floss hole 71 dischargings.Compressor 64, valve 68 and pressure-reducing valve 70 can be done manual operation by certain procedure operation or when need are cleared up condenser 12 to it by the timer (not shown).
In a preferred embodiment of the invention, preferably gatherer 60 and jars 62 is combined in the single casing 72, casing has an opening 74, and spheroid 26 is by this opening turnover.Gatherer 60 has sieve 76, store in order to recycling in order to tell spheroid 26 from the cooling fluid that is entered by opening 74 by pipeline 32.Jar 62 has a catch tray 78 and a pipe 80, and catch tray is in order to collect the cooling fluids that flowed out by sieve 76, and pipe hangs from above downwards from catch tray.Casing 72 also can be established a sight glass 82 so that observe the collection of spheroid 26 and emit with a drain valve 84 so that cleaning and maintenance.Gatherer 60 and jar 62 also can be done the split setting.
As shown in Figure 2, another characteristics of the present invention are, can be retrofited to spheroid EGR 30, make with spheroid 26 bring this device into be non-all also be that most cooling fluid is entered circulation and do not cause wherein a part to be discharged from floss hole 71 as waste liquid.In this case, the memory capacity of jar 62 can be given increasing, makes it have enough capacity to store the cooling fluid of all spheroid 26 being brought into gatherer 60.With regard to specific device, second jar 86 also can be set and by taking over 88 overflows of accepting from jar 62.In this case, compressor 64 is by air line 90 that valve 92 is housed and the pressure-reducing valve 94 feed compressed air that are connected with jar 86.Spheroid EGR 30 preferably has sensor 96a, 96b, in order to the big and amount low capacity of amount that is limited to cooling fluid in the spheroid EGR 30.
Now press the operation cycle of accompanying drawing 1a-1c explanation cleaning system 10.As shown in Figure 1a, spheroid 26 was stored in the gatherer 60 before with its directive pipeline 14 upstreams, shown in Fig. 1 b, spheroid 26 was dispersed in the whole condenser 12 before telling by separator 28, shown in Fig. 1 c, spheroid 26 was stored in the separator 28 before it is sent to spheroid EGR 30.
By open valve 68, shut off valve 70 also starts compressor 64 and makes compressed air enter jars 62 upstreams that can make the spheroid 26 directive condenser 12 under fluid pressure promotes in the gatherer 60 by ajutage 66.Leading pressure to jar 62 is regulated, and the injecting fluid of a constant volume is wherein flowed by pipe 80 and spheroid gatherer 60, thereby drive spheroid 26.When spheroid EGR 30 is emitted spheroid 26, the leading pressure in jars 62 close check valve 36 greater than cooling fluid downstream pressures in the condenser 12, make check valve 38 unlatchings simultaneously greater than cooling fluid upstream pressure condenser 12 in.Close and pressure-reducing valve 70 is opened at injection spheroid 26 back valves 68, make the pressure reduction that formation impels check valve 38 to close between the leading pressure in the cooling fluid of the condenser 12 of flowing through and jars 62.
After with somewhere, spheroid 26 directive condensers, 12 upstream, spheroid just is forced to pass condenser 12 and make clockwise direction circulation substantially along with cooling fluid main flows in the cleaning system 10.Spheroid 26 passes condenser tubes 14 and assembles in separator 28 sieves 58.Spheroid 26 is made slowly elliptical motion when condenser 12 downstreams flow to delivery channel 24 by bypass manifold 44 shown in A substantially at cooling fluid in the zone of sieve 58.
Generally be enough to make be non-all also be after big portion spheroid 26 accumulates in certain hour in the sieve 58, start spheroid EGR 30 and make that leading pressure drop to suddenly below the delivery channel 24 interior main pipe pressure in jars 62.This unexpected step-down is flowed the cooling fluid by separator 28 and is turned to suddenly, makes most of cooling fluid no longer emit along delivery channel 24 by fluid issuing 48 but emit along conduit 32 by spheroid outlet 50.Therefore, spheroid 26 is no longer done motion slowly but by the strong vortex of cooling fluid spheroid 26 is taken to spheroid EGR 30 by spheroid outlet 50 in sieve 58, thereby from sieving emptying spheroid 26 58.
From sieving 58 behind the emptying spheroid 26, regulating tank 62 internal pressures make the cool stream body weight of the separator 28 of flowing through flow to delivery channel 24 through fluid issuing 48 again.Emit and deposit jars 62 o'clock in by sieving 76 making the cooling fluid that drives spheroid 26, spheroid 26 is just accumulated in it in gatherer 60 by sieve 76, can make jars 62 to be full of cooling fluid in case of necessity, make the injecting fluid of the enough capacity of storage in jar so that will all exist the spheroid in jars 60 to inject entry conductor 22 from independent source.According to the speed that cover layer and other objects deposit, carry out above-mentioned circulation termly in condenser tubes 14.
Shown in Fig. 3 a-3g, in separator 28, taked further improvement so that discharge whole spheroids 26 58 from sieving.In shown in Fig. 3 a-3c separator 28 being made improvements, make fluid issuing 48 in shown in Fig. 3 d, the 3g separator 28 being made improvements, make fluid issuing 48 near inlet 46 near spheroids outlet 50.In general, it is 50 better that fluid issuing 48 is exported near spheroids, because the mobile spheroid 26 that impels of fluid by fluid issuing 48 be near spheroids outlet 50, thereby is convenient to the emptying spheroid.But, in some is installed, spatially can not satisfy this layout requirement, thereby just make fluid issuing 48 nearly inlets 46.
In general, improvement is to obtain following these effects.At first, reduce the eddy current that fluid issuing 48 causes because fluid is flowed through, particularly near spheroid outlet 50.Secondly, impel spheroid 26, make by the pulling force of the increase of the vortex that pressure drop caused in the spheroid conduit 32 to spheroid 26 near spheroid outlet 50.The 3rd, can act directly on the spheroid 26 substantially by the vortexs that pressure drop caused in the spheroid conduit 32, thereby increase pulling force spheroid 26.At last, the motion of about bundled ball body 26 and reduce spheroid 26 and depart from the degree that spheroid exports 50 axis, thereby increase the vortex pulling force that produces by the pressure drops in the conduit 32.
Shown in Fig. 3 a-3c, imperforate section 98 is set near near sieve 58 terminations and spheroid outlet 50 can makes sieve 58 be suitable for weakening near the spheroid 50 eddy current.Imperforate section 98 can do substantially that (Fig. 3 is a) to the extension of full circle tubular (Fig. 3 b) from half flute profile.Also can be to sieve 58 do flexible handle and can make separator 28 have infundibulate insert body 100 (Fig. 3 c), with its slot towards spheroid outlet 50 with its wide mouthful towards inlet 46.Sieve 58 and insertion body 100 constitute the wall body of continuity substantially, are the certain constraintss of spheroid 26 formations between inlet 46 and spheroid outlet 50.Insert the elliptical motion of body 100 about bundled ball bodies 26, make the pulling force of vortex more concentrated, so that export 50 emptying spheroids 26 by spheroid.
Shown in Fig. 3 d, 3e, make the imperforate section 102 close fluid issuings 48 in order to weaken eddy current on the sieve 58, thereby spheroid 26 suffered interference are reduced to a minimum.Can be provided with in separator 28 from spheroid outlet 50 makes spheroid 26 be easier to from separator 28 discharge with guiding by the vortex pulling force that pressure drop was produced in the conduit 32 to the insertion body 104 that inlet 46 extends.
Shown in Fig. 3 f-3g, retrofit to sieving 58, make it become the sieve 108 that shrinks shape sieve 106 or have tight waist portions 110.Sieve 106 dwindles the degree of scatter of spheroid 26 towards spheroid outlet 50, makes by the vortex that pressure drop caused in the conduit 32 to increase its pulling force to spheroid 26.On the contrary, sieve 108 makes spheroid 26 remain near the spheroid outlet 50 after spheroid is by tight waist portions 110, and here, vortex is easy to emptying spheroid from separator 28.
As shown in Figure 4, separator 112 has two components from device 112a, 112b.The structure of separator 112a, 112b is similar to separator 28, therefore, and to adopt identical numbering with class A of geometric unitA.Below for for the purpose of obviously, make inlet 46a and inlet 46b substantially toward each other, separator 112 also has valve 114a-114b, lays respectively at fluid issuing 48a, 48b.
The operation with regard to separator 112 now describes.In normal operation, valve 114a-114b opens, and makes the cooling fluid of the condenser tubes 12 of flowing through be divided into two equal portions substantially and flows to delivery channel 24 via separator 112a, 112b.Therefore, spheroid 26 is entering two separator 112a-112b by 30 ejaculations of spheroid EGR through being divided into two equal portions substantially after the condenser tubes 14.For clarity sake, accumulate in that spheroid 26 in the separator 112a is shown spheroid 26a and the spheroid 26 that accumulates in the separator 112b is shown spheroid 26b.
After spheroid 26 is assembled, temporary close one of among valve 114A, the 114b, for example valve 114a closes, so that from the emptying spheroid 26a of separator 112a.Shut off valve 114a turns to original fluid of flowing through separator 112a and makes the fluid of the condenser 12 of all the flowing through separator 112b that flows through, thereby spheroid 26a is rested in the sieve 58a zone substantially.The stop of spheroid 26a makes it be easy to make leading pressure among the spheroid conduit 32a be lower than leading pressure in the inlet 46a and make the separator 112a and cause under the situation of strong vortex and carry out emptying of flowing through starting spheroid EGR 30.Behind emptying spheroid 26a, valve 114a opens, valve 114b temporary close, thus make spheroid 26b emptying from separator 112b similarly.Behind emptying spheroid 26b, valve 114b opens again and makes separator 112 recover its normal running.
Fig. 5 a, 5b illustrate second embodiment 116 of cleaning system, wherein adopt the venturi apparatus 118 that is communicated with gatherer 60 by conduit 34, in order to spheroid 26 suction are positioned at the entry conductor 22 of condenser tubes 14 upstreams.Venturi apparatus 118 has the bypass manifold 120 between inlet tube 122 and outlet 124, bypass manifold has narrow section 126, make on the entry conductor 22 closing of normally open valve 128 cause fluid to turn to and the bypass manifold 120 of flowing through, thereby make high-velocity fluid suction spheroid 26 from gatherer 60 of the narrow section 126 of flowing through.Must be pointed out, even when valve 128 is opened, the fluid venturi apparatus 118 of still flowing through, but, because the diameter of entry conductor 22 there is no tangible pressure drop greater than narrow 126 diameter in inlet header case 16.Gatherer 60 preferably has the rotating sieve 130 under actuator 132 controls, makes it get first mode of operation so that keep and collect spheroid 26 here, gets second mode of operation so that emit spheroid 26 when valve 128 cuts out.
