Description
Technical field
The present invention relates to the method and apparatus removing incrustation scale and/or prevent incrustation scale.Especially, the present invention relates to from accommodate fluidic pipeline or other ducted bodies, remove incrustation scale or prevent that wherein incrustation scale gathers.
Background technology
The water hardness is the standard of measurement of calcium and magnesium ion concentration in the water.A lot of regional water hardness are generally very high in the world, and the very high meeting of the water hardness causes incrustation scale in pipeline or other water system inner accumulated.Incrustation scale is calcite structure (calcite structure) normally, and it forms the hard material of white usually.The calcite structure is the crystalline structure that is precipitated as the cubic(al)grating form of rule and densification by the lime carbonate molecule.Incrustation scale influences pipeline, valve or the pipe fitting of equipment usually, and these equipment comprise hot-water system, evaporative cooler, heat exchanger and cooling tower.Gathering of incrustation scale causes the transmission ofenergy loss, the higher and working cost increase of the used power of hot-water system and cooling tower.The incrustation scale of sufficient amount can gather and stop up the current by pipeline or this kind equipment pipe fitting.Incrustation scale also can promote the growth of mould (mould), mould and bacterium.
Relate to heating and flow through that the fluidic system of pipeline is easier to be subjected to the influence that solid sediment gathers, thereby this is to produce the possibility of leaving over fat, protein and mineral substance class dirt because the easier evaporation of the fluid of heating increases.This type of dirt is also sometimes referred to as " incrustation scale ".Here so-called " incrustation scale " except being closed by fat, protein, mineral substance and huge legendary turtle thereof the throw out of salt, also comprises microbial film and bioactive sludge.Therefore terminology used here " incrustation scale " mean comprise them be equal to the alternate material, thereby also mean pipeline or the intravital any solid sediment of other hollow.The present invention be more particularly directed to for example removal of incrustation scale in milk-product or the milk industry of food-processing or health processing industry.The pipeline inner fluid adds a pasteurization that example is a milk of hot-work.Incrustation scale produces in the pipeline that holds milk and dairy product, incrustation scale comprises sedimentary many types when milk heats, for example: when milk is heated to fatty deposit, proteins precipitate, the beta-lactoglobulin of 110 ℃ of formation and forms sedimentary mineral substance and the mineral substance huge legendary turtle is closed salt when milk is heated to more than 100 ℃.Traditional incrustation scale removal technology is not very effective for the removal of the incrustation scale that the inner-walls of duct that accommodates milk gathers, and this is because it is not suitable for the stalling characteristic (the distinct properties of milk) of milk.In this specification sheets, the incrustation scale that forms in holding the pipeline of milk of indication comprises when the throw out of milk along the temperature curve formed all kinds of when heating that comprises processing temperature.
At present existing a lot of equipment comprise: magnetic machine, electromagnetic system and electronics scale removal device (electronic de-scalers) in order to handle incrustation scale.
Magnet and magnetic machine provide limited incrustation scale removal effect, and have for example shortcoming of iron of the impurity of introducing, and iron is coated in the zone that is placed with magnet, thus the magnetic intensity of the magnet that further weakens.This method has the effect of permanently-polarised as everyone knows.The magnet that removes descale is difficult to correct the installation, and many experts think that magnet can not produce any significative results.
Electromagnetic system is worked in the mode that is similar to magnetic system, yet some electromagnetic systems are included as the magnetic field oscillation of payment permanent magnet poles effect.Magnetic effect only acts on short straight-tube portion, thus this system only partial action in the flow velocity of water by pipe section and water more senior general to cause handling the effect of magnetic system of incrustation scale more little.
Electronics scale removal device transmit electronic signal give around or near the coil of pipeline.Quite long pipeline has been crossed in final signal transmission, and what therefore have improvement avoids output incrustation scale effect.The example of electronics scale removal device is at United States Patent (USP) 5,514, sets forth to some extent in 283 and 5,074,998.
United States Patent (USP) 5,514,283 disclose a kind of water treatment device, and this device can prevent that incrustation scale from producing and removing the precipitation of scales thing.This device comprises the main coil of the pipeline outside that is installed in required processing.Circuit is electrically connected and transmits the successive radiofrequency signal and gives coil so that generate an electromagnetic field in water with main coil.The frequency of the actuation signal that produces by circuit and the control that amplitude is subjected to the microphone input.Microphone relies on the pipeline and monitors turbulent flow.The information that circuit will read from turbulent flow changes into signal and the actuation signal that produces of circuit is relevant with the turbulent flow of water thus.In the another one embodiment, actuation signal produces according to the transmitter in order to measure water flow velocity that is installed in the pipeline.Yet, the little help of this embodiment, this is exceedingly difficult because flow monitor is installed in pipeline.
Microphone is not effective ways of measuring water flow velocity, and this is because before signal is suitable for drive coil, needs a large amount of circuit in order to filter the signal by microphone generating.Microphone is influenced by other noise source interferential also easily, and this can cause uncertain signal is offered main coil.Also having a difficult problem is United States Patent (USP) 5,514, and 283 device mainly is designed for water and any gauged again method is not provided, so as its also can be applicable to water than other fluids with different qualities.
United States Patent (USP) 5,074,998 have also described a kind of device, and this device has coil can produce magnetic field in order to prevent in the pipeline incrustation scale and produce and also can remove descale in pipeline.Driven element provides the actuation signal of changeable frequency to coil.This device also can comprise transmitter, and this transmitter provides the data about water flow velocity in the pipeline, thereby can be made an explanation by controller can corresponding change actuation signal for these data.Flow rate sensor both can be intrusive mood (invasive) transmitter, also can be external sensor, and external sensor can be responded to coupling or be thermally coupled to pipeline.
For the intrusive mood transmitter is installed, must cuts off and open institute's metal conduit, so the installation costs height and the operational difficulty of intrusive mood transmitter.Therefore, the intrusive mood transmitter is very not attractive selection when the repacking existing installation.Induction coupling or thermal coupling transmitter have overcome the installation difficulty relevant with the intrusive mood transmitter.Yet induction coupling or thermal coupling transmitter are complex apparatus and compare the result of its generation with the intrusive mood transmitter accurate inadequately more.Although an embodiment described in the present invention does not comprise transmitter, United States Patent (USP) 5,074,998 are not described in this case the method for magnetic field for correcting characteristic again yet.With United States Patent (USP) 5,514,283 is disclosed similar, United States Patent (USP) 5,074, and disclosed device and be not suitable for the fluid different in 998 with the characteristic of water, therefore, the incrustation scale removal effect is not good in these cases.

Embodiment
With reference to the accompanying drawings 1, it provides the synoptic diagram of first embodiment of incrustation scale removal/preventer 10, and this incrustation scale removal/preventer 10 comprises the producer 15 with positive terminal 20 and negative terminal 30.Signal wire 40 makes between positive terminal 20 and the negative terminal 30 and is electrically connected.Signal wire 40 forms first coil 50 and second coil 60 round pipeline 70.Second circle, the 90 usefulness binding bands of first circle 80 of first coil 50 and second coil 60 or similar mode are fixed on the pipe 70.Same, last circle 110 usefulness binding bands of last circle 100 of first coil 50 and second coil 60 or similar mode are fixed on the pipe 70.First coil 50 and second coil 60 keep at a certain distance away separately, and this distance is equivalent to by a duct length that coil is occupied.Should be noted that incrustation scale removal/preventer 10 can only comprise a coil or also can comprise the coil of greater amt.Provide the power supply (not shown) in order to power to producer 15.When producer 15 excites generation signal 120, in accompanying drawing 3, illustrated quality of signals, signal is delivered to signal wire 40.
In order to calculate round the preferable methods of the total number of turns of the signal wire 40 (this signal wire has formed first coil 50 and second coil 60) of pipeline 70 by under establish an equation and provide:
The number of turn of every coil=(cross-sectional area of K * pipeline)/(electric current * coil quantity), it can be abbreviated as:
T＝(Kσ)/(IN)。
For all pipe diameters, constant K equals 15,000, and just negative float 20%.Therefore, for each different application of incrustation scale removal/preventer 10, after the different electric current outputs of having considered under the different mode of incrustation scale removal/preventer own, the preferred number of turn can be calculated acquisition.It should be noted that the K that under different environment, should use different numerical value.For example when pipeline 70 contains water, should use the K of different numerical value when containing milk with pipeline 70.
The number of turn of installing when incrustation scale removal/preventer 10 is during less than the specified numerical value of equation, during the entire cross section of passing pipeline 70 signal 120 will can not provide required frequency energy numerical value and therefore the incrustation scale effect removing/prevent will reduce.Increase surpasses the specified number of turn of equation as mentioned above, and this is only producing very little or inapparent improvement aspect incrustation scale removal.Yet the expense that the number of turn of greater number will increase incrustation scale remover 10 makes that also the installation of incrustation scale remover 10 is complicated simultaneously.In addition, increase the effect that the number of turn can cause permanently-polarised, this effect is similar to the effect that the prior art equipment that includes permanent magnet or oscillating magnet is suffered.Equation does not need all long correlation by coil 50 and 60 numbers of turn and pipeline 70, and makes that the intensity of signal 120 is relevant with the flow velocity of fluid 140 (shown in the accompanying drawing 2).Thus, incrustation scale removal/preventer 10 can adapt to different line sizes and not needs according to the data that produce by transmitter conditioning signal 120.
