Description
Technical field: the present invention relates to a kind of three-phase electromagnetic induction heating method is exactly positive 3n (n >=1) limit tee section three-dimensional winding iron core liquid three-phase electromagnetic induction heating method
Background technology:
At present for the electromagnetic-induction heating method of heating liquid, mainly contain high frequency and refined two kinds of work.Chinese patent ZL200810022997.5 and ZL201010113132.7 is high-frequency electromagnetic induction heating; European patent EP 0383272A2 and Chinese patent ZL97106984.4 is power frequency heating; Chinese patent ZL0111341874 and Chinese patent ZL201110340219.2 is three-phase main-frequency electromagnetic induction heating; The product of these two patents and exploitation thereof, is better than existing like product in efficient, life-span, environmental protection and security performance etc.But also there are following two major defects in these two patents and products thereof: the iron core of (1) heater is EI structure, the length of each phase magnetic circuit is different, in any case arrange one, two windings and each annex, all cannot ensure structural three-phase symmetrical, all cannot obtain the magnetic distribution of three-phase symmetrical, thus can not reach optimum in energy-conservation, efficient, life-span, security performance etc.(2) heater surrounds the Secondary Winding of iron core and each phase winding, and being the main heating element of heater, is again protecting sheathing and the radiator of iron core and each phase winding.This structure, makes iron core, a winding and main heating element and by between heating liquid, there is direct heat exchange, and the temperature exporting hydrothermal solution directly will affect the temperature rise of iron core and a winding, even causes the accelerated ageing of iron core and a winding.When the bad condition such as open-phase operation or terminal short-circuit appears in power distribution network, this structure may cause the overheated of certain phase iron core or winding.
Summary of the invention:
The invention discloses a kind of positive 3n limit tee section three-dimensional winding iron core liquid three-phase electromagnetic induction heating method.The three-dimensional winding iron core structure of positive 3n (n >=1) the limit tee section of the method, completely different from the core structure structure of ZL0111341874 and ZL201110340219.2 and other electromagnetic induction heater, as shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4, Fig. 5, Fig. 6.This three-dimensional winding iron core can adopt conventional cold-reduced silicon sheet also can adopt non-crystaline amorphous metal, even can adopt the amorphous and nanocrystalline soft magnetic alloy material that magnetic characteristic is more excellent.
The three-dimensional winding iron core structure of this 3n limit tee section ensure that heater three-phase magnetic circuit full symmetric, on this basis, the installation of a winding, the installation of the liquid inner cool tube line of iron core and a winding and extraction, the installation of totally-enclosed Secondary Winding (circle) is fixed, the installation of cylindrical tube shape outer wall is fixed, even the extraction etc. of a winding power line, can ensure three-phase full symmetric.Thus ensure that the three-phase full symmetric of this heating means and the overall electromagnetic field of device.The three-dimensional winding iron core structure of this three-phase full symmetric, in low-loss, low noise, the aspects such as volume is little, strong overload capacity, to compare with the iron core of other structure with EI and have significant advantage, exciting current even can reduce by 92%, falls damage and can reach 25-35% (cold rolled silicon steel).
Heater of the present invention: assemble a winding on the three-dimensional winding iron core of 3n limit tee section is the inwall of heating container by the closed stainless steel case surrounding iron core and a winding, to be also the number of turn be 1 Secondary Winding, as shown in Figure 7, Figure 8; Double-deck cylindrical tube shape stainless steel case is the outer wall of heating container, as shown in Figure 1, Figure 2, shown in Fig. 4, Fig. 5.Principle of heating of the present invention: the internal layer of the inner and outer wall of heating container concentrates heating, the liquid of heating container inside self distribution heating.This mode of heating is substantially identical with line-frequency induction heating with existing high frequency.Greatest feature of the present invention and technical advantage, have employed positive 3n limit tee section three-dimensional winding iron core, and three-phase symmetrical each annex (comprising each fixed installation point) is set, ensure that the hree-phase symmetry in heater overall structure, thus ensure that the full symmetric distribution of whole heater three-phase electricity magnetic field.This is also the essential distinction of the present invention and existing similar inventions patent and product.The foundation stone of the series of advantages such as this is that the present invention is efficient, energy-conservation, safety, environmental protection, occupation of land are few.
Iron core of the present invention and a winding adopt the type of cooling cold in liquid.Iron core of the present invention and a winding, the tubular structure formed by stainless steel material is totally-enclosed to be wrapped, the totally enclosed closed surface shell of this tubular, to be the equivalent number of turn be 1 3n Secondary Winding, being the inwall of heating container, is also the concentrated heater of a heating liquid, as shown in Figure 7, Figure 8; Another concentrated calandria of heater be the inwall of double-deck cylindrical tube shape totally enclosed frame as shown in Figure 1, Figure 2, shown in Fig. 4, Fig. 5.Arrange the liquid inner cool tube line of vertical direction at each rib place of positive 3n (n >=1) limit shape and (or) every limit midline, iron core and a winding and cooling system heat-barrier material thereof and Secondary Winding are isolated.The heat that the cooling tube tape of iron core and a winding is walked still heats the liquid in low-temperature insulation container.The structure that iron core and a winding and Secondary Winding are isolated is the difference of another essence of the present invention and patent ZL0111341874 and ZL201110340219.2.This structure of the present invention, substantially increases the temperature range of heater heat outputting liquid.This restricts the deciding factor of the temperature of patent ZL0111341874 and ZL201110340219.2 heat outputting liquid just.Because two parts exist direct heat exchange, the temperature exporting hydrothermal solution directly affects the temperature rise of iron core and a winding, even causes the accelerated ageing of iron core and a winding, reduces service life.Heater is connected on the secondary side of power distribution network, when there is voltage or current fluctuation in distribution secondary, because existing three-phase main-frequency induction heating apparatus cannot ensure the full symmetric of three-phase magnetic circuit, the saturated of certain phase or heterogeneous magnetic circuit can be caused, the loss of part iron core and a winding can sharply increase, and the temperature now in high-temp liquid container has been in rated temperature, the fast ripe heat radiation of high-temp liquid container cannot be passed through, thus part iron core and a winding temperature can be caused to rise fast, insulate heat is caused to puncture the whole heater of harm, even can bring out pernicious security incident.This is the present invention's basic reason that the two is separated just.In order to make full use of all heat energy, the present invention needs to arrange at least low and high temperature two liquid topic cool-bags, the wherein cooling system heat exchange of low-temperature insulation container and iron core and a winding, can be the Inlet fluid that high-temperature heating liquid cool-bag provides uniform temperature.The heat of this iron core of the present invention, a winding and Secondary Winding is isolated, and is valuable feature of the present invention.The isolation technology of this iron core, a winding and heater, heating container, has two important function: (1) makes the output temperature of heater can enclose interior adjustment certain; (2) solve the heat dissipation problem of iron core and a winding system, fundamentally ensure that safety and the life-span of iron core and a winding.When power distribution network occurs that voltage and current fluctuates, automatic regulating system can also regulate the temperature of iron core and a winding cooling liquid, safety and energy-conservation between, the present invention ensure that safety first from the operation principle of heater.
The present invention the tap different according to winding can realize the adjustment of output liquid temperature.The tap of the different number of turn of correspondence of a winding is set and leading-out terminal.Because the number of turn of a winding is fewer, power output is larger, if a ceiling voltage presses 400V (virtual value) design, and a corresponding minimum power output of the full number of turn of winding.A winding is merotomized, draws with the form of tap, the hydrothermal solution temperature that the corresponding needs of each group tap export.Adopt a simple intelligent controller, just can realize output liquid temperature, safe and energy-conservation automatic adjustment.
The present invention has the function of certain digestion Distribution Network Harmonics.Different from the power supply of existing all kinds of power frequency and high-frequency electromagnetic induction liquid heating, the present invention allows containing a series of higher hamonic wave in three phase mains, and when humorous containing high order in power supply, the efficiency of heating surface is higher.This is because the high frequency electric source of existing thermatron is quadratic transformation, must be lossy, and power supply of the present invention directly takes from power distribution network; The electromagnetic induction heating efficiency of high frequency is higher, but iron loss and copper loss are also higher, direct safety and the life-span affecting iron core and a winding, iron core of the present invention and winding have independently cooling system and heater and high-temp liquid container to be isolate, thus the higher hamonic wave of power distribution network can be made full use of, not only efficient but also safety.This is ZL200810022997.5, ZL201010113132.7, ZL0111341874, ZL201110340219.2 etc., all unserviceable.Along with the increase of harmonic load and the networking of various clean energy resource, the harmonic content of power distribution network increases and low-pressure side is active, and the harmonic wave digesting power distribution network even can obtain the award of power supply department.
The present invention can the various clean energy resource of efficiency utilization (for solar photovoltaic generation system).A winding electric source of the present invention has a set of parallel connection power supply switching device shifter, can attack directly to be switched to solar photovoltaic generation system and directly to power.Existing nearly all liquid electric Metal-magnetic needle, all need be reverse into (three-phase) power frequency supply or be modulated into high frequency electric source, this pilot process must have certain energy loss (efficiency of inverter be about 80%, the efficiency of high-frequency converter lower).Solar photovoltaic powered system of the present invention only needs 6 IGCTs and simple delay control circuit, as shown in Figure 9, output voltage waveforms as shown in Figure 10, wherein E is the DC voltage of solar photovoltaic powered system, T is the artificial selected primitive period, such as can select T=0.02 second, usually according to the DC voltage E of photovoltaic power supply system and the temperature integrated selected of output liquid.The Fourier progression of Figure 10 is
This is the three-phase non-sinusoidal voltage of one group of symmetry, does not have DC component.It is better when this three-phase voltage only has first-harmonic to heating effect ratio of the present invention.Time in the direct current of clean energy resource containing larger ripple, heating efficiency of the present invention is higher.Visible electric power system of the present invention is convenient very flexibly, compared with the induction heater needing power frequency or high frequency electric source to power, substantially reduces the added losses of electric power system, improve the power supplying efficiency of clean energy resource system with other.
The present invention can realize the distributed heating of liquid self.The present invention creates the electromagnetic fiele distribution of space symmetr and three-phase full symmetric in heating container inside.The electromagnetic fiele of this three-phase full symmetric, by the loss of magnetic reversals of liquid and polarization loss, can realize the distributed heating of liquid self, improves the efficiency of heating surface of heater.
The present invention can suppress the formation of incrustation scale or other carbon deposit, dirt effectively.The present invention creates the electromagnetic fiele distribution of space symmetr and three-phase full symmetric in heating container inside, make molecule (atom) remagnetization and the polarization fast in a plurality of directions of fluid molecule and impurity, effectively prevent the formation of incrustation scale, carbon deposit and dirt.
The iron core of heater of the present invention and a winding, sealed completely by the inwall of heating container, defines the Secondary Winding (circle) of three-phase full symmetric as shown in Figure 7, Figure 8.The electric current of Secondary Winding has two, and one is the circulation around each post (comprising vertical and all cylinders that are level) axis; One is perpendicular to the circulation in each closed-loop path of bottom surface, is being parallel to the algebraical sum identically vanishing of Zhong Ge limit, two loops up and down electric current of bottom surface.Spatially the Secondary Winding (outer wall of heating container is cylindric) of three-phase symmetrical, creates the Magnetic fluxleakage distribution of three-phase symmetrical, as shown in figure 11.Figure 11 is the space Magnetic fluxleakage distribution schematic diagram of a certain moment heating container inside.In electromagnetic fiele, magnetic field and electric field are interdependences, and by the restriction of drawing instrument, electric-field intensity line (power line) orthogonal with magnetic induction line in Figure 11 does not draw.
As can be seen from Figure 11, stray field take vertical center line as axle three-phase symmetrical; About perpendicular in the laterally zygomorphic plane of split of center line, stray field is symmetrical up and down; The stray field three-phase symmetrical that 3n limit on each horizontal plane is other.The in like manner piezomagnetic theory three-phase symmetrical of each position and magnetic field orthotropic.This is that one can be rated as perfect SYMMETRIC ELECTROMAGNETIC field distribution.The magnetic distribution of this space of the present invention and three-phase full symmetric has two important function: (1) makes liquid from the elect magnetic field heating in space and three-phase symmetrical.Different from the concentrated heating of heating container inside and outside wall, this is a kind of distributed heating.By polarization loss and the magnetization loss liquid conducting self-heating of liquid, further increase the efficiency of heating surface.(2) make the molecule of liquid, the molecule of impurity or atom, at the elect magnetic field of space full symmetric and three-phase full symmetric, almost comprehensive remagnetization and polarization, effectively prevent the formation of incrustation scale, carbon deposit or dirt.In electromagnetic fiele, fluid molecule or impurity molecule (atom), be subject to the effect of two kinds of moments, the moment of magnetic dipole and the moment of electric dipole, and these two kinds of moments are spatially orthogonal, differ in time
(to first-harmonic
), quick shift (magnetization and polarization are alternately) in a plurality of directions, impurity is difficult to be formed incrustation scale, carbon deposit or dirt by absorption.
Inwall (the Secondary Winding adding the heating container of this special shape of hot charging of the present invention, also be main calandria), area is large, space and three-phase full symmetric, the electromagnetic fiele produced also is space and three-phase full symmetric, heating surface (area) (HS is large, homogeneous heating, the efficiency of heating surface is high, is obviously better than existing three-phase electromagnetic induction heating method and device.
The outer wall of heating container of the present invention adopts double-deck cylindrical tube shape structure, and interlayer can vacuumize, also can filling with insulation material, to reduce heat loss.
Maximum technical advantage of the present invention have employed positive 3n limit tee section three-dimensional winding iron core.Such as n=1, phase sequence clockwise A, B, C; As n=2, phase sequence clockwise A, B, C, A, B, C; As n=3, phase sequence clockwise A, B, C, A, B, C, A, B, C;Due to the container outer wall of 3n limit tee section three-dimensional winding iron core and cylindrical tube shape, ensure that the hree-phase symmetry in overall structure.This iron core and outer wall construction, ensure that the inner cold system adding iron core and a winding, various annex, fixed position and weldment, lead-in wire and outlet etc., still can keep the full symmetric on three-phase structure.Structural three-phase symmetrical ensure that the three-phase symmetrical electrically.Ensure that the full symmetric distribution in the three-phase electricity magnetic field of heater.This is greatest feature of the present invention, is also basic assurance and the theoretical foundation of the series of advantages such as efficient, energy-conservation, safety, occupation of land are few.
