Description

In a large amount of gas, produce the method and the equipment thereof of pressure pulse

The invention relates in a large amount of gas, particularly be contained in and produce the method for may command pressure pulse selectively in the gas in large-sized space.Here a large amount of gas of indication also comprises the mixture of all gases, for example air.

The invention still further relates to the equipment that is used to realize said method.

The processing of the mechanical energy that the generation pressure pulse need improve in a large amount of gas.The energy of this raising shows as the potential energy form of local compression in a large amount of gases and the kinetic energy that is changed by local velocity.Energy in the pulse is swung between the maximum value zero, and the energy of two kinds of forms is synchronous each other.

The energy of this pressure pulse can be used for different purposes under certain conditions, such as preventing that the particle in this gas from falling on the space sidewall that holds this gas, and will fall and become a kind of tectal this particle removal on the above-mentioned sidewall and fall.This pulse also can be used to promote the mixing of two kinds of gas with various working medium, is used for mixing and being used to make a kind of gas to obtain uniform others of a kind of gas and this pearl of liquid or solid particle.Like this; the processing of all gases of occasion that the application of pressure pulse just can be used for cleaning and that will mix in industrial different phase, that burn, chemical reaction, work done etc., and be used for processing to the working medium of the form of the solid particle that is suspended in gas or liquid bead.

A kind of feasible condition of a large amount of gases being carried out this processing is the pulse with a sizable acoustic energy.

For processing, when the frequency of its used pulse the following optimum efficiency that obtains in limited time near the sound that can hear at above-mentioned these air in using.Be unlike in the damping that the pulse under this low frequency is subjected to and go through evil under the upper frequency like that.In addition, long wavelength can make pulse round stopping that dividing plate propagates into all parts that reach this space with uniform acoustic pressure power level.

For a large amount of gas is handled, the known method that is used to produce pressure pulse or sound wave in the time of in gas is contained in large-sized space does not also have to produce enough energy and satisfies above-mentioned various application.

The pressure pulse that produces in a large amount of gases for example has been used for the cleaning to the component sidewall that holds gas.But, lack pulse oscillator and limited the cleaning that is applied to this class formation of reduced size with enough efficient.

Adopt example that ping cleans in Swedish patent file 80 07 150-9 numbers (publication number is 425 No. 597) and in No. 2033130, the B. P., all to disclose.

By disclosed method in the above-mentioned file, the pulse energy that is produced is higher, but many applications are still disliked too low.

Specially planting in the file 8007 150-9 number disclosed method in Sweden is the pressure difference of utilizing between two spaces that periodically are communicated with each other, when gas since exist pressure difference by a space when flow in another space, just produced pulse.Pulse oscillator comprises a pipe that is used to produce pressed gas, and this pipe is provided with one by engine-driven rotating cylinder valve.The pipe of mutual coaxial arrangement and valve and be provided with a groove.When valve rotates at the groove on the valve just through the groove on the pipe, then pipe with around it between just form and be communicated with, just two grooves outflows by aligning mutually of gas thus so just produce a pulse.This pulse is amplified in a resonatron then, and its frequency is about 20 hertz.Adopting the resulting waveform of this device is sinusoidal wave basically, and the energy distribution that this waveform was caused in the pulse interval is unfavorable.Between around the inside of this pipe and it, keep this pressure difference value, just need supply pressure air continuously.The compressor that is used to produce pressed gas so just need be that back pressure works without cessation with the pressure of gas pipe.Therefore need a higher useful horsepower input that is used for the compression work that is directly proportional with the acoustic energy that obtains.The major part of this merit is as heat loss.In addition, pulse has just produced when pressurized gas.Owing to have valve, these valves just dash and do not leave pipe, so its energy can not be utilized.This energy also falls as heat loss.The low acoustic efficiency of this method has limited obtainable output power economically and in fact all.

And the sounding device of being introduced for No. 2033130 for british patent specification, the generation of ping is that the opening between two spaces that can periodically be communicated with mutually of a gas stream through having different pressures is produced.In this situation, this opening is by the to-and-fro motion guiding valve control of the diaphragm of a closed end that is connected resonatron.On a certain initial position, when guiding valve is restricted to a narrow groove with opening, just produce a very weak low-frequency sound wave, this diaphragm is being vibrated under the determined a certain frequency by resonatron.Promote like this this guiding valve under same frequency back and forth fortune  torr dip in pain Chi y order  tomb  yarn and alarm cutting to pieces and sillyly bury lettuce and closely question and receive the pretty U Buddhist nunnery of the well-behaved a small tinkling bell of  location ⑸  demons and monsters  and show favour to that to closely question the wet ɡ  of the Na barium Wen meat and fish dishes Lu 007150-9 number existing shortcoming of raising identical.But, there is an advantage to utilize positive feedback to reach, guaranteed harmonious between the resonant frequency of resonatron and the pulse frequency by this diaphragm.

Employing is by No. 2033130 disclosed methods of british patent specification, and maximum can reach the sound output of 1.5Kw.Be intended for use to blow off cigarette ash as a modified model and use, be used for such as crossing hot heater, heat exchanger, the metal cleaning equipment of steam boiler factories such as vapor economizer and preheater.Because the output of the power of this pulse oscillator is restricted this method and can only be used for less factory.For the joint device of the boiler that surpasses 300 megawatts and the cleaning of crossing hot heater, the power of the pulse that is taken place is not enough.

An object of the present invention is to provide a kind of method that is used for producing at a large amount of gas pressure pulse, total power that this method provided is higher than the known numerical value that the whole bag of tricks reached.

Reach according to this purpose of the present invention, wherein specified this method comprises that described pulse is produced by a valveless displacement device in introduction, wherein when equipment pressure of pulsating pressure and a large amount of gases when exit orifice is opened be different.

Another object of the present invention provides a kind of equipment, and total sound output of the pressure pulse that this equipment produced will be higher than the known numerical value that various pressure pulse generator reached.

According to the present invention, this purpose reaches, specified this a kind of valveless displacement device that produces described pulse that comprises in introduction wherein, and be to design like this, promptly when this equipment when its exit orifice is opened, the pressure in the equipment is different with pressure in a large amount of gases.

According to optimum implementation of the present invention, the working condition of this equipment such as same compressor, and also the pressure in the described equipment is the pressure that surpasses a large amount of gases.So just lead and set up a kind of favourable power relation between the consumption the worker of resultant sound output and this equipment.

Under some application, designing the pressure that a kind of like this equipment is lower than in a large amount of gases its pressure in this equipment can be more better.But this selection scheme can cause top pointed power relation to reach lower value.

The same with the whole bag of tricks in the above each patent publications, utilized the pressure difference value in two spaces that can periodically be interconnected to produce pulse according to method of the present invention.

Mention as the front, the pulse that known method produced all is sine-shaped, but by means of according to method for generating pulse of the present invention, can obtain a kind of the flowing of very high speed of the opening that just is communicated with in the very short starting stage of pulse interval of flowing through, pulse interval is more slowly by the mobile of opening when stopping.Flow strong concentrate and help the sound output that reaches high, because the sound output of fluctuation and being directly proportional with the speed difference integrated square of gas mean velocity.

Another importance according to method for generating pulse of the present invention is that pulse is directly to produce by means of the device of setting up pressure difference between two spaces that can periodically be communicated with each other.Under this condition, when it carried out work as compressor, the consumption of its energy was limited in being used for the compression work energy needed according to equipment of the present invention, up to this equipment till the moment that its outlet is opened.The gas that exports of flowing through makes the working room of compressor and the pressure difference between its outlet reach balance in this moment soon.Because the pressure in outlet passage is atmospheric pressure normally, the remaining gas part that is used to replace in the working room no longer needs work done.Owing to produce stress-free gas, thereby its energy changes into immediately the acoustic energy in the working room except being pressed at short notice, is increased considerably aspect acoustic efficiency.

In addition, because pulse is directly to produce by the outlet of gas stream through equipment, this sound wave energy can be utilized, otherwise it is increasing to become in pressurized container.

According to the present invention, the generation of pulse is to be based upon on the basis of the principle that can form high power pulse.According to distinguished characteristics of the present invention, it be in the pulse interval with efficiently finish and with the energy changing of strengthening.The sound output that the pulse that can produce had is more much higher than the numerical value that has been reached up to now thus.This just makes it reach the degree that in fact can't reach with known the whole bag of tricks to the various application facet that the pressure pulse processing of this a large amount of gases is mentioned on be used for.

The detailed description of most preferred embodiment of the present invention is explained further that these embodiments just play an exemplary role in this application below with reference to following accompanying drawing.

Fig. 1 represents to be used to clear up a kind of pulsing device of steam boiler;

Fig. 2 represents a schematic top view of compressor shown in Figure 3, and this diagrammatic sketch has deleted some to the invention belongs to the detail section of non-main contents.

Fig. 3 represents a schematic representation as a pulse oscillator of compressor operating;

Fig. 4 is an air velocity of passing through the exit orifice of compressor with curve representation in the release.

Fig. 5 shows the embodiment who goes in a large amount of gases with pulse distribution to two separation.

Fig. 1 represents a kind of steam boiler 27, is stained with cigarette ash and similar sediments on the internal surface of this boiler.A kind of equipment that comprises pulse oscillator 2 of the present invention is connected on the steam boiler 27 by an air conduit 4.Pressure in the steam boiler 27 is for being lower than the some millibars of barometric pressure.It between pulse oscillator 2 and steam boiler a resonator 3.

Pulse oscillator 2 is one and has the male rotor 13 that is meshed and the screw compressor of female rotor 14.Because such compressor is well-known, so its working principle is just enough as long as be briefly described.

In Fig. 2 and compressor shown in Figure 3, male rotor 13 has two spirality leaf lobes 15, and this leaf lobe mainly is positioned at and changes in the outside of pitch circle and have protruding geometric form.Between two leaf lobes, be formed with two spiral grooves.Female rotor 14 has three spirality leaf lobes 16 that have middle groove in corresponding mode.The leaf lobe 16 of female rotor 14 mainly is positioned at the inside of the pitch circle of this rotor, and has the side of spill.

The leaf lobe 15,16 of rotor 13,14 is meshing with each other with each groove and cooperates, and forms a man type working room between rotor 13,14 and cylindrical shell on every side 25.Cylindrical shell 25 has two cylinders and intersects the shape that forms, and each cylinder is equipped with one in the rotor 13,14.During rotation, the working room is moved axially to the other end that has outlet by an end that has entry port of this equipment 2.

Only be connected in each working room of aeration phase with entry port, at this moment air is sucked in the working room, at compression stage entry port and outlet are all closed, at this moment air is carried towards outlet, compress simultaneously, and only be connected with outlet at exhaust phase, at this moment air leaves the working room.

This compressor 2 carries out work with overcompression, promptly the air compression in the working room is arrived the pressure level that surpasses the pressure in the outlet passage 4.This excess pressure is appropriate, and its value is about 0.3 to 1 crust.When being communicated with outlet, air just flows out from the working room with high speed, and this excess pressure just feeds through to outlet passage 4 by exit orifice 23, and pressure there is near atmospheric pressure.Produce outside fast flowing by pressure difference, and only occurred over just the working room in the initial very short period, produced a very strong pressure pulse thus.Therefore the pressure in the both sides of exit orifice 23 is balance basically, and exhaust process is under the ever-reduced situation of the volume of working room, and only the displacement by air realizes.Change in flow is very strong in the pulse interval like this.

In Fig. 4, with curve representation air velocity by outlet between working room's exhaust cycle.Obtained strong pressure pulse in the starting stage of exhaust process.After this, outwards flow out with quite low speed.This speed value is unsettled, swings owing to be subjected to high-speed influence to produce some in the starting stage.

Transient energy value in a surge movement is and square being directly proportional of the difference of instantaneous velocity and mean velocity.The concentration degree that is concentrated to an acoustic energy in the short burst like this in period of waves still is listed as more by force than its rate process.This will cause the output of its power than a pure sinusoidal waveform can reach usually much higher.

In the illustrated process, its pulse frequency is 20 hertz in plotted curve.T on the t coordinate just represents 0.05 second like this.When the working room towards the moment that outlet is opened, this compressor is to carry out work under the over pressure condition greater than barometric pressure 0.32 crust.

Exit orifice 23 is radial and axial guiding.The radial directed in hole 23 partly is by three edge section 24a, b, and c forms.The first edge section 24a is by a bit the beginning of the half of intersections of two cylindrical shells on the cylindrical shell 25, and stretches out obliquely and reaches high pressure end wall 26 to cylindrical shell one side of something that male rotor 13 is installed.The second edge section 24b be by the half of intersections of two cylindrical shells on the cylindrical shell 25 but be positioned at than above-mentioned first more by a bit the beginning of entrance point, extend upward and arrive high pressure end wall 26 obliquely along cylindrical shell one side of something that female rotor 14 is installed.The 3rd edge section 24c with the intersection conllinear of cylindrical shell, couples together above-mentioned two points.

The axial lead in hole 23 partly is by three edge section 24d, e, and f forms.The first edge section 24d is by beginning the loading body 17 that (the first edge section 24d place of the radial directed part that this point is 23 two end part in the hole) extends internally agley and radially extend male rotor 13 on the point on the outward edge of end wall 26.The second edge section 24e by on the outward edge of end wall 26 a bit on begin the dress carrier 18 that female rotor 14 is inwardly stretched out and radially extended in (the second edge section 24b place that this point is the radial directed part at 23 two end part in the hole) agley.The 3rd edge section 24f is that two the inners with an above-mentioned 24d edge section and the 2nd 24e edge section couple together.

In order to obtain to produce the peak output of pulse, rotor leaf lobe 15,16 is done fan addiction 9,20 on its circle edge, so that can instantaneously open.For the same reason, the edge section 24a of exit orifice, b, d, its shape of e, in the moment of opening, edge 19,20 that corresponding leaf lobe 15,16 with it, 21,22 parallel.

The interior stream of air and outflow are all by leaf lobe 15,16 Collaborative Control that have the aperture.Being communicated with between working room and its outlet passage 4 is at the edge, tip 19,20 of the leaf lobe 15,16 that advances to above-mentioned working room with in the end edge 21 of the rear end of above-mentioned leaf lobe like this, 22 respective edges section 24a through outlet 23, b, d, the moment of e opens.Therefore, do not need valve that the interior stream and the outflow of air are controlled.

In the moment that the inside and the passage between the outlet passage 4 of equipment 2 have just been opened, as shown in Figures 2 and 3, air just between the edge, tip 19 of the edge section 24a by exit orifice 23 and male rotor lobes lobe 15 formed groove and between the edge, tip 20 of the edge section 24b of exit orifice and male rotor lobes lobe 16 formed groove radially flow out, and between the back edge 21 of edge section 24d that passes through at exit orifice and male rotor lobes lobe 15 the groove that forms and between the back edge 22 of the edge section 24e of exit orifice and female rotor lobes lobe 16 formed groove shaft to outflow.

In most preferred embodiment, a leaf lobe group of being made up of several leaf lobes is selected.Enter each working room with regard to the air that makes large volume like this, and can also be with the edge section 24a of the exit orifice 23 of the work that matches with each leaf lobe, b, d, the total length of e is done more greatly.Big edge length produces superior unlatching performance, because strive maximum flow in the moment of opening, so that the pulse that obtains concentrating.The tip speed of rotor 13,14 is faster, just opens sooner, and in given pulse under frequency condition, leaf lobe number tip speed more at least is higher.The number of leaf lobe 15,16 can be 3 or less.Rotor 13,14 has the leaf lobe 15,16 of unequal number, so that each leaf lobe is opened synchronously towards outlet.A kind of low frequency obtains with respect to rotor thus, and the volume of air with big as far as possible unit pulse obtains in addition.The rotating speed of compressor 2 is selected like this, pulse frequency is in 10 to 50 hertz of scopes, and optimum value is about 20 hertz.Can to reach maximum value be 20 kilowatts sound output in the pulse of Chan Shenging like this.

Pressure pulse imports steam boiler 27(Fig. 1 into by a pipe-line system that comprises passage 4 resonator 3).Resonator 3 between compressor 2 and steam boiler 27 amplifies with the basic sound wave of the pulse that is produced by compressor 2.The length of resonator 3 will be joined, so that provide and the i.e. 20 hertz of mutually harmonious a kind of resonant frequencies of the frequency of pulse for a large amount of air in this system.

In order to remove the cigarette ash that adheres on steam boiler 27 each wall, do not need pulse oscillator to carry out work continuously.Interval between each operation cycle must be able to not too prolong on the other hand, because can make soot layer thickness too big so that steam boiler work Economy is had a negative impact like that.In many cases, with 10 minutes interval, he was a suitable circulation in the cycle for the worker in 30 seconds.For the interval of the such weak point between two operation cycles, when being in pause period, generally do not advocate to stop the work of compressor.A large amount of startings then will cause this compressor parts heavy wear.

For compressor 2 is turned round continuously, be provided with air tapping equipment 5,6.Compressor inlet is led to from the working room that closes in a return flow line 6 that disposes cut-off valve 5.By opening cut-off valve 5, the atmospheric pressure that makes pressure in the working room and compressor 2 be in emissions status balances each other.Because when outage period, compressor 2 is running downs, so energy consumption can be ignored.

When pulse frequency with the resonant frequency of the air of pulse transmission to the pipe-line system of steam boiler 27 when corresponding, then the pulse on each wall of steam boiler 27 just reaches maximum intensity.

This situation can reach according to two kinds of different modes in principle.Both can make it consistent, and also can make it consistent by changing resonant frequency with pulse frequency by changing pulse frequency with the resonant frequency of this system.In first kind of mode, can come to the resonance directions adjustment by the rpm of adjusting compressor 2.

In the embodiment shown in fig. 1, control procedure is to realize by the resonant frequency that changes resonator 3.Resonator 3 one of configuration can be by the end wall 7 of a certain reference position displacement for this purpose.The size of resonator 3 will be done to such an extent that can provide an i.e. resonant frequency of 20 hertz of pulse frequency that roughly is equivalent at a certain temperature to intrasystem air, and makes this end wall 7 place its reference position.In the course of the work, this end wall 7 is adjusted on the position that accurate resonance takes place.In this case, can compensate for the intake temperature deviation with for the deviation of other parameter of the resonant frequency that may change this system.This movable end wall 7 also provides the possibility that compressor 2 is turned round under other revolution, because the position of this end wall 7 can be complementary with the pulse frequency that has changed.

The position of end wall 7 can be by for example being arranged on steam boiler 27 certain point of inside on sensor device 8 measure that the intensity of pulse controls, end wall 7 is moved to through measurement to have on the position of maximum strength then.This process preferably utilizes a microprocessor 9 to carry out automatically.The pulse strength that also can utilize movable end wall 7 to control in the steam boiler 27 makes it reach a certain numerical value that departs from maximum strength, and this may occur in some cases, therefore needs.

Amplification adjustment by means of movable end wall in the resonator can replace with the method for air temperature in this system of change or replenish.Because wavelength is directly proportional with the velocity of sound, and the velocity of sound is directly proportional with the square root of kelvin temperature, so variation of temperature will change the resonant frequency of this system.The adjustment of temperature can realize by many modes: by the variable restrictor in compressor 2 inlet passages 12; Guiding valve by can regulating compressor internal compression rate to one of compressor 2 configuration or by with air by compressor outlet passage 4 or turn back to its import by his chamber of a certain worker who closes and can realize.And the adjustment of temperature can also be controlled by the signal that is passed by sound intensity sensor 8.

As to the replacement of the resonator of a separation or to it replenish, a large amount of gases 1 steam boiler 27 in itself just can be used as a resonator, the resonant frequencies that can adjust pulse frequency and these a large amount of gases 1 are complementary.Use this pulse and do not adopt the resonance amplification of any kind also can accomplish.

Being provided with that a return passage 11 is used for air is led to import by outlet passage 4 is needs, in order to avoid a large amount of colder air are pumped in the steam boiler 27.Because pressure steam boiler 27 in is a little less than atmospheric pressure, certain of the upstream extremity that this just need flow in return air is provided with the air inlet restriction (about 1 millibar) of an appropriateness on a bit.

In embodiment described and expression in the drawings, pulse produces by a compressor, and the air in this compressor in the working room had been compressed to a certain excess pressure before being discharged from through the air outlet.Provide a kind of favourable economic operation to the energy consumption aspect like this.

In another embodiment, not shown, pulse is to produce on the opposite direction of outlet with air stream.This produces by a displacement device, and this establishes fan the air gas and not compressed of stand by pump, for example by a root's blower or a kind ofly do not have the screw compressor of internal compression to finish.In this embodiment, need be with the air throttling in the inlet passage of equipment to about 0.5 crust or lower.This force value will be retained to this working room when outlet is opened till.Basically the air that is in atmosphere pressure state in this moment is entered through the air outlet with high speed flow by outlet passage and is in the working room that is lower than atmospheric pressure, produces a strong pressure pulse thus.Because the volume of this working room constantly dwindles, air just is compressed and turns back to outlet passage then.

The consumption of this replacement type embodiment desired power will be higher than described above a kind of.This power is to become heat waste to lose to a great extent.A small amount of empty cloud is pumped in the boiler thereby these air have higher temperature.

In represented embodiment, certain work cycle is described.This circulation certainly changes with respect to work and the length of outage period.Work cycle also can be such, has been to obtain the pulse frequency that changes between two different numerical value, and the revolution of equipment changed between two operation cycles.And when this equipment running hours, the frequency that this pulse oscillator can change is carried out work.

When carrying out work, if when requiring to have maximum amplification in whole circulation, then suggestion correspondingly changes the resonant frequency of system, for example carries out displacement by the end wall 7 with resonator 3 between the position of two separation and realizes with the frequency that changes.

Described equipment is not the single space that is only limited to cleaning steam boiler factory.By channel system being provided with a subchannel, as shown in Figure 5, then pulse can transfer to two or more separated spaces 1 ', 1 " in.Can under situation about hocketing, be to realize to each separated space while or the cleaning that hockets thus by mobile conversion equipment of configuration in the subchannel.
