Description

Technical Field

[0001] The utility model relates to the technical field of electrode boilers, in particular to an electrode boiler with cyclic heat exchange. Background Art

[0002] Electrode boilers are heated by electrodes. Electrode heating is a technology that uses the high thermal resistance of water to directly convert electrical energy into thermal energy and generate steam. The heating voltage uses medium voltage electricity, with a voltage of ≥6kV. The same boiler has different heating voltages and different powers, because the heating power is proportional to the square of the voltage.

[0003] In the patent document with publication number CN214094414U, an electrode boiler with cyclic heat exchange is disclosed. The device uses a condensing shell and a reflux pipe to allow the steam generated by the electrode boiler body during use to enter the condensing shell, cool down, and then flow back to the inside of the electrode boiler body through the reflux pipe. This can reduce the pressure on the electrode boiler body during use, prevent damage to the boiler due to excessive internal pressure, and reduce the probability of dry burning of the electrode boiler.

[0004] However, the insulation protection and buffering effect of the device for electrode boilers still need to be improved.

[0005] Therefore, we propose an electrode boiler with cyclic heat exchange to solve the above problems. Utility Model Content

[0012] Preferably, the top structure of the buffer plate is an arc-shaped surface, so that it can fit well with the bottom of the boiler shell, thereby further improving the stability of the boiler shell.
