Description

An electrode boiler based on pressure regulation system

technical field

The present invention relates to the field of boilers, in particular to an electrode boiler based on a pressure regulation system.

Background technique

With the continuous improvement of boiler technology's requirements for "carbon peaking" and "carbon neutrality", the grid-connected scale of wind, solar and other renewable energy sources in China continues to grow rapidly. Renewable energy consumption space, on the other hand, also provides a more flexible technical form for renewable energy heating, providing higher flexibility and reliability for the entire power system.

Due to the inability to form a good fit between wind resources, light resources and electrical load demands in terms of time and region, the development of new energy in the Three North Regions of my country is faced with the problem of high curtailment of wind and light. During the heating period in winter, in order to meet the heating demand, it is necessary to maintain a high electrical load, which reduces the peak-shaving capacity of the power grid, which directly causes a large number of wind power and photovoltaics to be unable to connect to the Internet, resulting in abandoned wind and solar energy, wasting a lot of resources. "Setting electricity by heat" mainly means that the power generation of the unit is constrained by the heat load and does not have the ability to adjust. Therefore, this type of electricity cannot participate in the peak regulation of the power grid, which increases the difficulty of "shaving peaks and filling valleys" in the power grid.

The realization means of power to heat technology mainly include resistance boiler and electrode boiler. However, because of its low power, resistance boilers have a maximum thermal power of only 6 MW, which makes it difficult to achieve large-scale consumption of wind and solar energy. The high-voltage electrode boiler has the characteristics of high power, high energy saving, high efficiency, high safety, high stability, no pollution, no noise, no emission and long life, and has excellent technical advantages compared with conventional resistance boilers.

In order to effectively adjust the power of the electrode boiler, an existing method is to adjust the position of the adjusting shield provided on the outer casing of the phase electrode by adjusting mechanisms such as lead screw structure and adjusting gear, so as to realize the power adjustment of the counter electrode boiler. In the water environment, the adjusting gear is easily damaged and the maintenance cost is high.

Preferably, the detection unit includes:

The pressure detection unit is arranged inside the first flow channel, detects the steam pressure, and is connected with the control unit;

The pneumatic piston pushes up and down according to the steam generated by the electrolyzed water inside the first flow channel;

Detection unit detection and control principle:

As shown in Figure 15, the control unit includes a rotary valve 13, two conductive resistors 12 and a resistance baffle 11. The rotary valve is connected to the pressure monitoring unit, and the pneumatic piston is connected to one of the conductive resistors. The pneumatic piston is due to the steam content in the boiler body.

The pressure detection unit formulates a depressurization control signal to the control module, and sends an alarm signal to the control unit. The control center sends out control signals to reduce the internal pressure of the boiler and improve the electrical stability of the overall device and the power conversion efficiency of the device.

As shown in Figure 1-13, the control method of the present invention includes:

Power control principle:

The power control process includes a power transmitter and a liquid level sensor. The power transmitter is detected by the signal of the electric power transmitter to form a power control signal. The liquid level sensor measures the liquid level of the inner cylinder; as shown in Figure 1, the power control It is completed by comparing the signal detection of the electric power transmitter WT with the set power, and the power control signal corresponds to the inner cylinder liquid level control signal. The power transmitter WT is composed of three-phase power superposition, and the output power of the full scale is 8 MW.

The size of the water resistance R is related to the water level of the inner cylinder. The rise and fall of the water level H1 in the inner cylinder corresponds to the fall and rise of the water resistance R, the electric power W and R are inversely proportional, and the fall and rise of R corresponds to the rise and fall of the electric power W, that is, the rise and fall of H1 corresponds to the rise and fall of the electric power W.

Power control method: Act on the circulating pump according to the deviation between the power and the set value. If the actual power is lower than the set value, the water level in the inner cylinder should be increased; otherwise, the water level in the inner cylinder should be lowered. Specifically, when the boiler power is lower than the set value, the frequency of the circulating pump should be increased; if the power reaches the set value, the frequency of the circulating pump should be reduced to keep the water level constant and the outlet water temperature at the set value.

Pressure control principle:

The pressure control mainly detects the pressure of the inner cylinder through the pressure gauge. The pressure gauge is located in the upper half of the outer cylinder of the boiler to measure the inner pressure of the boiler and ensure that the pressure does not exceed the safety limit, and is not lower than the corresponding saturation pressure of the hot water temperature of the inner cylinder. ; As shown in Figure 2, the pressure control method: the increase of the pressure is realized by the nitrogen pressurization system. When the pressure is increased, the electric valve 2 of the pressure system is opened to supplement the nitrogen in the furnace to increase the boiler pressure; the pressure is reduced by the exhaust electric valve. Valve 1 is realized. When the boiler pressure exceeds the design value of 1 MPa, in order to ensure the stable operation of the boiler, the boiler exhaust gas regulating valve is opened to remove part of the gas in the furnace to reduce the pressure in the furnace. The exhaust regulating valve should also be opened regularly for a period of time to remove the hydrogen that may be generated.

Temperature control principle:

Thermometer: A thermometer is set at the hot water outlet and the outlet of the three-way valve at the user end of the heat exchanger; as shown in Figure 3 and Figure 4, the control of the hot water temperature at the user end is achieved by changing the thermal power. The control of the outlet water temperature of the pneumatic three-way valve is realized by changing the opening degree of the bypass side of the pneumatic three-way valve. If the return water temperature is higher than the set value, reduce the opening of the bypass side of the three-way valve.

Inner cylinder water level control principle:

Water level transmitter: The water level measurement range of the inner cylinder is H1=(0~1200 mm) (4~20 mA). The normal inner cylinder water level is controlled by the power signal, and the water level is controlled between the minimum 300 mm and the maximum 1100 mm.

As shown in Figure 5 and Figure 6, when the boiler is in normal operation, the circulating pump in the inner cylinder is always running. Through the detection of the water level by the differential pressure transmitter in the inner cylinder, the feedback signal is provided to the drain valve and the circulating pump, and the frequency of the circulating pump is adjusted. , used to control the water level of the inner cylinder. The opening of the drain valve increases and decreases, corresponding to the decrease and increase of the water level H in the inner barrel; the frequency of the circulating pump adjusts the water level in the inner barrel. When the frequency of the circulating pump increases, the water level in the inner barrel increases; otherwise, the water level in the inner barrel decreases.

Total water control principle:

Differential pressure transmitter for inner and outer cylinders: The inner and outer cylinders are equipped with differential pressure transmitters to obtain the liquid level of the inner and outer cylinders. The inner cylinder measures the liquid level to calculate the water volume of the inner cylinder and converts it into volume. After conversion, the volume is added to the liquid level of the outer cylinder. The corresponding volume does not exceed the upper critical value, that is, when all the water in the inner cylinder is discharged to the outer cylinder, the liquid level does not exceed the safe water level of the outer cylinder.

As shown in Figure 7, there is a sewage outlet at the bottom of the outer cylinder. When the total water volume exceeds the range, open the outer cylinder drain valve and discharge through the outer cylinder drain valve. When the total water volume is lower than the range, add water through the feed pump to raise the water level in the cylinder.

Conductivity control principle:

Conductivity measuring instrument: The conductivity detector is arranged at the inlet of the circulating water in the inner cylinder.

As shown in Figure 8, the conductivity control method: improving the conductivity is achieved by adding trisodium phosphate concentrate in the circulating water, and the dosing port is set before the inlet of the inner cylinder of the boiler circulating water. Reduce the conductivity and discharge the solution in the outer cylinder through the sewage outlet, and at the same time, the feed pump adds demineralized water into the outer cylinder. During operation, the electrical conductivity is converted to normal temperature electrical conductivity within a certain range. An early warning signal should be given if the conductivity is too high.

Safety protection process:

As shown in Figure 9 and Figure 10, due to the particularity of using high-voltage electricity in the high-voltage electrode boiler, each phase electrode is equipped with voltage and current monitoring, and the electrode should be powered off immediately when the following problems occur:

1) Over current protection/short circuit protection. Trigger overcurrent/short circuit protection when the real-time current is greater than the rated current;

2) Phase loss protection. It means that there is no voltage on one or two live wires. When any one phase detects that the voltage is 0, the phase loss protection is triggered;

3) Three-phase unbalance protection. The reason for the voltage bias is that there are relatively many loads driven by one phase or two phases, and the load asymmetry leads to the problem of electrification of the boiler shell. During operation, the three-phase voltage unbalance degree does not exceed 10%, and the three-phase unbalance protection mechanism is triggered when the boiler runs within the unbalanced range.

4) Leakage protection. The grounding wire of the outer cylinder of the boiler is also equipped with voltage monitoring. When the measured voltage is greater than the set safety value, the leakage protection will be triggered. In addition, the metal shell of the boiler, its power cabinet, and the control cabinet or the metal parts that may be charged should be connected to the grounding terminal. Have a reliable electrical connection, and the connection resistance between it and the ground terminal should not be greater than 0.1Ω. The grounding wire and the grounding terminal should have sufficient current-carrying capacity and size respectively to be able to withstand the maximum grounding current that may be generated, and meet the relevant requirements of GB50065; the grounding resistance is generally not greater than 4Ω.

Step SA1: Turn on the machine, it can only be started when the boiler is in a cooling state;

Step SA2: start the electrical safety protection system, the hydrogen control system and the inner tank water level high limit control system;
