Embodiment
Voltage between electrode is certain and the timing of electrolyte concentration one, and the amount of ions in unit volume is constant, at this moment
The contact area of electrode and electrolyte solution determines the size of heating power.By adjusting electrolyte level Level Change electrode
Submergence, so as to change the contact area of electrode and electrolyte solution, it is possible to achieve regulate and control the purpose of heating power.
In the heated by electrodes equipment of high-power generation steam, it need to ensure to be heated electrolyte concentration stabilization.
The utility model is provided with high-order and two water tanks of low level, uses frequency conversion flow circulating pump, controller and fluid tube
The common internal circulating load for maintaining electrolyte changes the flow of frequency variable circulating pump to keep the concentration of electrolyte aqueous solution in elevated tank
To change the liquid level of elevated tank, reach adjustment heating power purpose.This method is easy to by entering to elevated tank
The structure design at the mouth of a river, it is ensured that current can accomplish that the effusion for being electrolysed aerogenesis is seldom to the souring very little of electrode, and
And electrode corrosion is also very small.
As depicted in figs. 1 and 2, the voltage of three phase mains 5 is applied between three-phase electrode 1 and elevated tank 6 for principle, electricity
The electrolyte of interpolar occurs Ion transfer and produces electric current, and electrolyte is heated.
Elevated tank 6, it is interior to contain high-order electrolyte aqueous solution 2, the high-order electrolyte aqueous solution 2 and low level electrolyte water
Solution 4 is relative, is that the setting in height is different, the low level electrolyte 4 is located in lower water box 8.High-temperature water tank bottom is set
Fluid tube 3 is equipped with, low level electrolyte aqueous solution 4 can be transported to high-order electrolyte aqueous solution 2 by frequency variable circulating pump 7.
When increasing the flow of frequency variable circulating pump 7, due to being equivalently employed without changing by the flow of fluid tube 3, in a high position
The liquid level of electrolyte 2 in water tank 6 rises, the contact area increase with three-phase electrode 1, so increase heating power, passes through control
Device, to stablize the liquid level of high-order electrolyte aqueous solution 2.If reducing power, reduce the flow of frequency variable circulating pump, make
The liquid level of high-order electrolyte aqueous solution 2 reduces.
Three-phase electrode 1 includes the sub- phase electrodes of L1, L2, L3 tri-, and the three roots phase electrode is connected with three phase mains,

As shown in figure 3, it is a high-power electrode constructed by liquid level PCU Power Conditioning Unit in the utility model embodiment
Steam boiler, the bottom of boiler body 31 is electrolyte aqueous solution 26 in lower water box, is electrolyte 23 in elevated tank 24, phase
Electrode is made up of sub- phase electrode 22, described to form the annular combustion perpendicular to the water surface by multiple electrodes body per height phase electrode 22,
Phase electrode is fixed in the electrode tip holder 21 on boiler body 32；Electrolyte 26 enters circulating pump 28 by pump suction pipe 27, passes through
Water pump outlet pipe 29 is sent into elevated tank 14 from water distributor 25.
Start frequency variable circulating pump 28 when boiler works, otherwise the electrolyte concentration in elevated tank 24 is defeated with water vapour
Going out to become increasing, the electrolyte concentration in lower water box can become more and more lower with the backflow of system condensate again,
The circulating pump opened between high-low-position water tank makes solution constantly mix, and to keep electrolyte concentration constant, frequency variable circulating pump 28 starts
Afterwards, the fluid flow flowed down by adjusting the flow of frequency variable circulating pump 28 to make from fluid tube 30 injects less than frequency variable circulating pump 28
Fluid flow, raise the high-order liquid level of electrolyte 23, the electrode body of sub- phase electrode 22 is gradually inserted in electrolyte 23.

When increase frequency variable circulating pump flow when, then the liquid level of electrolyte 3 gradually rises in elevated tank, heating power with
Increase；Conversely, when reducing the flow of frequency variable circulating pump 28, then the liquid level of electrolyte 3 reduces in elevated tank 24, heating power
Reduce.Citing：The flow of frequency variable circulating pump 28 is adjusted to maximum, the liquid level of electrolyte 23 in elevated tank 24 constantly rises, when upper
When being raised to the electrode body for being totally submerged sub- phase electrode 22, controller control frequency variable circulating pump 28 flow, which is equal to, to be passed through in fluid tube 30
The fluid flow flowed down, the liquid level in elevated tank 24 is set to keep constant, then boiler power output reaches 100%.
If controller at this moment is set into input power as the 50% of rated value, controller controls the stream of frequency variable circulating pump 28
Amount reduces so that the flow of frequency variable circulating pump 28 is less than the fluid flow for passing through and being flowed down in fluid tube 30, then the liquid in elevated tank
Potential drop is low, when being reduced to 50% height, the flow increase of frequency variable circulating pump 28 so that the flow of frequency variable circulating pump 28, which is equal to, to be passed through
The fluid flow flowed down in fluid tube 30, then the liquid level in elevated tank 24 maintain again stabilization.So repeatedly, it is required to control
Heating power.
The phase electrode applied in the utility model includes three sub- phase electrodes 22, and three sub- phase electrodes 22 mutually completely cut off, and
Fixed afterwards by electrode tip holder 21 together by wire harness binding.
As shown in figure 4, phase electrode includes three sub- phase electrodes, two of which is sub- phase electrode 32,35, and also one is not shown
Go out, all fixed per height phase electrode by electrode tip holder, the sub- phase electrode 32 is fixed by electrode tip holder 33, the sub- phase electrode 35
Fixed by electrode tip holder 34, three sub- phase electrodes are connected with three phase mains.
In general, the number of phases is more, using the teaching of the invention it is possible to provide electric current it is bigger.According to demand, the utility model can also provide more
Height phase electrode, to tackling phase power supply, can also more height phase electrodes be connected to the one of which of polyphase source, so as to according to need
Ask and power is controlled.
For the utility model without that can continuously adjust heating power by outside machinery, this method will not cause power to dash forward
Become, and electrode life is grown, and electrolysis aerogenesis hardly occurs, is extremely secure, and there will not be mechanical breakdown.
