An electrode boiler is also called an electrode boiler, and is a boiler that heats water using electric energy. A conventional electrode boiler is disclosed in patent document No. CN 111623331A.
Taking a liquid level regulating electrode boiler as an example, the heating principle is as follows: the three-phase electrode in the boiler inner cylinder is immersed in the boiler water containing electrolyte, and the boiler water with certain conductivity is directly heated after the three-phase electrode is electrified. The furnace water is used as a conductor in the heating process, high-voltage current is generated in the furnace water, and the furnace water is rapidly heated, so that controllable hot water or steam is generated. The water circulation inside the furnace is that hot water in the inner cylinder flows into the outer cylinder by means of gravity, and the water circulation outside the furnace is that water in the outer cylinder enters the inner cylinder after heat exchange through the heat exchanger by the circulating pump. The boiler inner cylinder is isolated from the outer cylinder by adopting an insulating material, and the connection of the inner cylinder and the outer cylinder is insulated. The liquid level regulating electrode boiler forms zero potential at the center of the inner cylinder due to the symmetrical structural characteristics of the electrodes (the neutral point is formed at the center point of three phases due to symmetry), and the outer cylinder body of the boiler and water flow are prevented from being electrified.
However, when the hot water in the inner cylinder flows into the outer cylinder by gravity, the liquid level of the hot water in the outer cylinder is impacted, so that the liquid level measurement of the outer cylinder is inaccurate; moreover, the hot water in the inner cylinder falls into the central point of the liquid level of the hot water in the outer cylinder, so that the hot water in the outer cylinder is not uniformly mixed, and the temperature of the output hot water is unstable.
