It will be understood by those skilled in the art that the present invention may be practiced without some of these specific details. In some instances, methods, instrumentalities well known to those skilled in the art have not been described in detail in order to not unnecessarily obscure the present invention.
Example (b): as shown in fig. 1, an electrode boiler device and a control method thereof, include a furnace body 1, a drain 13 arranged at the bottom end of the furnace body 1, a circulating water outlet 2 and a water outlet 12 at the side of the bottom, a second thermometer 11 at the inner side of the bottom, a circulating water inlet 3 at the middle bottom, a pressure gauge 5 at the middle top, an air inlet valve 6 and an exhaust valve 8 at the top, and an electrode 7 at the top, wherein a lifting device 15 is connected with an inner furnace 14 and the furnace body 1, a three-way valve 16 and an electrode 7 of the circulating water inlet 3 are connected with the inner furnace 14, a pressure difference transmitter 4 and a first thermometer 9 are arranged at the bottom end of the inner furnace 14, and a drain valve 10 is arranged at a bulge at the bottom end of the inner furnace 14.

The electrode 7 in the inner furnace 14 is in a net shape, the electrode 7 is made of chromium-zirconium-copper or Q345 steel, and a conducting rod of the electrode 7 penetrates through an insulating porcelain bushing of the furnace body 1 and then is electrically connected with a power bus.
And the water level of the water level transmitter 4 is controlled between the lowest 300 mm and the highest 1100 mm.
The furnace body 1 is 5000 mm high and 2400 mm in diameter.
The diameter of the drain valve 10, the circulating water outlet 2, the circulating water inlet 3, the water outlet 12 and the sewage outlet 13 is 165 mm.
As shown in fig. 2, the pipe wall of the three-way valve 16 is slidably connected with the inner furnace 14, and the inner furnace 14 at the connection position is provided with a spring and a limiting groove.
The method for controlling the lifting of the inner furnace comprises the following steps: the movement control end of the lifting device 15 controls the expansion amplitude of the lifting device 15, so that the inner furnace 14 is controlled to ascend and descend, and the contact area of the electrode 7 and water is changed.
As shown in fig. 3, the power control method: and the signal detection of the electric power transmitter is compared with the set power, and the power control signal corresponds to the liquid level control signal of the inner furnace 14. The power transmitter is formed by superposing three phases of power, and the output power of the full range is 8 MW. According to the deviation of the power and the set value, the power acts on the circulating pump, if the actual power is lower than the set value, the water level of the inner furnace 14 is required to be increased, and otherwise, the water level of the inner furnace 14 is required to be reduced. Specifically, when the boiler power is lower than a set value, the frequency of the circulating pump is increased; and if the power reaches a set value, reducing the frequency of the circulating pump, keeping the water level of the inner furnace 14 constant and keeping the water outlet temperature at the set value.
The water level control method comprises the following steps: when the boiler normally operates, the internal furnace 14 circulating pump is always in an operating state, and through the detection water level of the pressure difference transmitter 4, a feedback signal is provided for the drain valve 10 and the circulating pump, so that the frequency of the circulating pump is adjusted, and the internal furnace 14 water level is controlled. The opening degree of the drain valve 10 is increased and decreased, and the water level of the internal furnace 14 is correspondingly decreased and increased; the water level of the inner furnace 14 is adjusted by the frequency of the circulating pump, and when the frequency of the circulating pump is increased, the water level of the inner furnace 14 is increased; otherwise, the water level of the inner furnace 14 is reduced.
The pressure control method comprises the following steps: the pressure is increased by a nitrogen pressurization system, and when the pressure is increased, the air inlet valve 6 is opened to supplement nitrogen in the boiler so as to increase the pressure of the boiler; the pressure reduction is realized through the exhaust and exhaust valve 8, when the pressure of the boiler exceeds the designed value of 1 MPa, in order to ensure the stable operation of the boiler, the exhaust and exhaust valve 8 of the boiler is opened, and partial gas in the boiler is exhausted, so that the pressure in the boiler is reduced. The vent valve 8 should also be timed to open for a period of time to exclude hydrogen gas that may be generated.
The temperature control method comprises the following steps: the control of the hot water temperature at the water outlet 12 is achieved by varying the thermal power. When the hot water temperature at the water outlet 12 is low, the opening degree of the drain valve 10 is increased, and the water flow is increased.
Total water flow control method: when the total water quantity exceeds the range, a drain outlet 13 is opened for draining; when the total water quantity is lower than the range, water is added through a water feeding pump.
The method for controlling the conductivity comprises the following steps: the conductivity is improved by adding a concentrated solution of trisodium phosphate into the circulating water, and a dosing port is arranged in front of a circulating water inlet 3. The solution in the outer furnace is discharged through a sewage discharge outlet 13, and simultaneously, the feed pump adds demineralized water into the outer furnace to reduce the conductivity. When the conductivity is too high, the conductivity measuring instrument indicates that the early warning signal lamp is on.
The three-phase electrode is directly immersed in water in the internal furnace 14, furnace water added with trisodium phosphate concentrated solution generates current after being electrified, and the furnace water is rapidly heated under the action of the current. When the equipment normally runs or is in a hot standby state, the total amount of water in the outer cylinder of the boiler needs to be kept unchanged, and deoxidized cooling water and electrolyte water added with trisodium phosphate concentrated solution are continuously supplemented.
The boiler device is a three-phase Y-type wiring, each phase is connected with an electrode, and current is directly led into water and flows from a phase electrode to a neutral zero electrode. The high-voltage electrode immerses the water in the inner furnace 14, the inner furnace 14 is in a three-leaf petal shape, the center point of each petal is located at the center of the inner furnace 14, 3 partitions of the inner furnace 14 are uniformly distributed and crossed at 120 degrees, and the bottoms of the partitions of the inner furnace 14 are communicated. The number of high-voltage electrodes is designed according to the electric power of the boiler, and each phase voltage is sent to the corresponding phase electrode by a circuit 2, so that the load current of a single access end is reduced, and the reliability of connection is ensured. Wherein, the electrode material adopts chromium zirconium copper or Q345 steel, and the exterior of the phase electrode is covered with a conductive anticorrosive coating.
The voltage and current monitoring is arranged on each phase electrode of the electrode boiler, and the electrodes are required to be powered off immediately when the following problems occur: triggering over-current/short-circuit protection when the real-time current is monitored to be larger than the rated current; one or two live wires have no voltage, and when the voltage monitored by any phase is 0, the phase-missing protection is triggered; the reason for the voltage phase deviation is that the load driven by a certain phase or two phases is relatively more, and the problem of electrification of the boiler shell is caused by asymmetric load. In the operation process, the unbalance degree of the three-phase voltage does not exceed 10%, and a three-phase unbalance protection mechanism is triggered when the boiler operates in an unbalance range. The grounding wire of the outer cylinder of the boiler is also provided with a voltage monitor, when the measured voltage is greater than a set safety value, the leakage protection is triggered, in addition, the metal shells of the boiler and a power cabinet and a control cabinet thereof or a metal piece which is possibly electrified are reliably electrically connected with the grounding end, and the connecting resistance between the boiler and the grounding end is not greater than 0.1 omega.
