Problems solved by technology
However, electrode heating will always be accompanied by electrode corrosion and water electrolysis to generate gas. Electrode corrosion will affect the service life of electrodes; water electrolysis consumes electric energy, which will reduce the efficiency of electric heating, and hydrogen accumulation may also cause safety hazards.

Abstract
The invention discloses a novel immersed heating electrode. The novel immersed heating electrode comprises an electrode body and an electrode stem. The electrode body is of a closed hollow barrel-shaped structure with an arc-shaped upper top and an arc-shaped lower bottom. Through holes are formed in the arc-shaped upper top and the arc-shaped lower bottom. The lower end of the electrode stem is fixed to the arc-shaped upper top, the electrode stem is sleeved with an insulation ceramic protection tube, and the upper end of the electrode stem is exposed out of the insulation ceramic protection tube. The electrode body is arranged to be in the shape of a hollow barrel with the arc-shaped upper top and the arc-shaped lower bottom, so that the contact area of the electrode and water is increased, and the current intensity of the surface of the electrode is lowered. Meanwhile, the adsorbability of the electrode to gas generated by electrolysis of water is increased, so that corrosion of the electrode is effectively stopped. Meanwhile, by means of the through holes formed in the arc-shaped upper top and the arc-shaped lower bottom of the electrode body, the stability of the electrode body in water is guaranteed.
Description
technical field [0001] The invention relates to the field of electric heating, in particular to a novel immersion heating electrode. Background technique [0002] In electric boiler heating technology, resistance heating is an indirect heating method, relying on high-temperature wall-to-water heat transfer, so it is difficult to avoid heat loss and electric heating response lag; the current of electrode heating directly acts on water to generate heat, during the heating process The heat loss generated is extremely small, and at the same time, the electrode heating can also use high-voltage electricity above 10kV, which has a wide voltage range and can withstand the impact of grid voltage fluctuations. Therefore, electrode heating technology is almost the only choice for large-scale electric boiler equipment. [0003] In addition to high thermal efficiency, electrode heating also has the advantages of fast response speed, high reliability, and low failure rate of electric hea...
