Description

Technical Field

[0001] The utility model relates to an electrode boiler, in particular to a desalted water level sampling system in an inner cylinder of a high-voltage electrode boiler. Background Art

[0002] At present, the electrode boilers on the market use 10KV high-voltage alternating current to directly heat and produce hot water. The high-voltage electrode boiler is a device that uses the high thermal resistance of water to directly convert electrical energy into thermal energy. After power is turned on, a certain amount of special electrolyte solution is added to the boiler water to make the boiler water conductive at the same time. Due to the conductivity of the water, resistance is generated, and heat is generated to turn the water into high-temperature water. The water can be stored in the heat storage tank during off-peak hours and released during the peak hours of electricity consumption during the day to transport heat. The liquid level of the conductive desalted water in the inner cylinder plays a vital role in the safety and stable operation of the high-voltage electrode boiler. Since the electrode boiler is a closed pressure vessel, the inner cylinder is arranged in the outer cylinder, and the inner cylinder and the outer cylinder are in an insulated isolation state. The inner cylinder carries high voltage electricity. How to set a level meter outside the boiler to conveniently observe the liquid level of the inner cylinder and directly observe the liquid level of the desalted water in the inner cylinder has become a problem that needs to be solved.
