Description

Technical Field

[0001] The utility model relates to an electrode hot water boiler, in particular to a fully immersed three-phase electrode hot water boiler with uniform output of each electrode. Background Art

[0002] The fully immersed electrode hot water boiler uses 10KV high-voltage three-phase AC electrodes to energize the boiler water in the boiler, and uses the high thermal resistance of water to directly convert electrical energy into thermal energy. A certain amount of special electrolyte solution is added to the boiler water of this boiler to make the boiler water conductive and generate resistance. The three three-phase electrodes form a current loop through the boiler water to heat the boiler water. The entire electrode boiler is a closed container, and a water separation plate is set at the bottom of the closed boiler cylinder. The water separation plate separates the lower part of the furnace cavity from the middle and upper parts. A lower protective shield with electrodes is fixed in the furnace body above the water separation plate, and a lower protective shield is fixed directly above the lower protective shield. An upper protective shield with electrodes is provided, and the upper protective shield and the lower protective shield are provided correspondingly. A liftable protective shield is provided between the upper protective shield and the lower protective shield, and the electrode is suspended in the liftable protective shield between the upper protective shield and the lower protective shield. The above three sets of protective shields are provided in the furnace body, and three-phase electrodes are provided correspondingly. The furnace body is filled with boiler water, and each protective shield and the motor are fully immersed in the boiler water; desalinated cold water enters the furnace body cavity below the water distribution plate from the middle water inlet at the lower end of the boiler body, and a plurality of internal water inlets are evenly distributed on the water distribution plate. The cold water in the furnace body cavity below the water distribution plate enters the furnace body cavity through these internal water inlets. The water moves upward and is heated by the three-phase electrodes to become hot water, which is then output from the hot water outlet at the top of the boiler. The liftable protective shields of the three electrodes are connected to a lift operating rod. The lift mechanism is raised or lowered by operating the lift operating rod to achieve the up and down movement of the three liftable protective shields. The movement of the three liftable protective shields can change the resistance between the electrodes, thereby adjusting the thermal power of the boiler. The desalted water in the fully immersed electrode hot water boiler is always in a dynamic circulation process. Therefore, the water flowing through the three electrodes is required to be as uniform and uniform as possible. The existing equipment has limited space in the furnace cavity below the water distribution plate. , the cold water entering from the center of the bottom of the boiler cannot be evenly distributed to the internal water inlets, resulting in uneven output of the three electrodes; in addition, during the operation of the boiler, if it appears at extremely low load (below 15%), or high load (above 95%), or other abnormal operating conditions, it is very easy to produce water electrolysis reaction, and produce trace amounts of hydrogen on the electrodes. The conventional upper protective shield needs to fix the sealed conductive rod and the insulating porcelain bottle, and the top is sealed. Hydrogen will gather in the upper protective shield. When the hydrogen gathers to a certain extent, it may explode. How to solve this problem is a problem that the existing equipment needs to solve. Summary of the invention
