Fully submerged electrode boiler with internal water distributor structure

Abstract

This application discloses a fully submerged electrode boiler with an internal water distributor structure, including a pot shell, a phase electrode, a zero electrode and an isolation shield. The phase electrode and the zero electrode are fixed in the pot shell, and the phase electrode is located In the zero electrode, the isolation shield is movably arranged in the pot shell, and the isolation shield is located between the phase electrode and the zero electrode, the number of the phase electrode and the zero electrode is equal, and the number of the phase electrode It is an integer multiple of 3. Optionally, it also includes a water distributor, a connecting pipe and a flexible sealing sheet. The water port is sealed with the flexible sealing sheet, the water outlet port of the zero electrode is open, the water inlet of the water distributor communicates with the circulation outlet, and the water outlet of the water distributor communicates with the circulation outlet through the connecting pipe. The spaces in the zero electrode are connected, and the tube lengths of each connecting tube are equal.

Description

technical field [0001] The invention relates to the field of boilers, in particular to a fully submerged electrode boiler with an internal water distributor structure. Background technique [0002] Patent CN110375286A provides a fully submerged electrode steam boiler with a circulation device. This kind of boiler is powered by three-phase electricity, and three pairs of phase electrodes (reference number 2 in the document) and zero electrode (document In reference number 5), each pair of phase electrodes and the zero electrode rely on the water between the two to conduct electricity, and each phase electrode is connected to a live wire of three-phase electricity. In this electrode steam boiler, a partition (reference number 6 in the text) is set in the pot shell, and the space in the boiler is divided into upper and lower parts by the partition. The upper part is water with a higher temperature, and the lower part is water. The water with a lower temperature and the lower p...

Problems solved by technology

[0003] Since the water under the partition is continuously gushing towards the phase electrode and the zero electrode, and the water inlet end of the zero electrode is completely open, so when the water under the partition gushes to the zero electrode There is a turbulent flow phenomenon, so the water flow into each zero electrode per unit time is different, and the water flow through each zero electrode per unit time is different, which further leads to three zeros. The temperature of the water in the electrodes is inconsistent, and the inconsistent water temperature will cause the conductivity of the water to be different, and the conductivity will be different. The resistance between the phase electrodes and the zero electrodes is inconsistent, and the resistance between the three pairs of phase electrodes and the zero electrodes is inconsistent, which will cause the power supply equipment to trip

To sum up, in order to avoid tripping, the electric boiler provided by the patent CN110375286A must ensure that the water flow into each zero electrode in a unit time is consistent, and the completely open state of the water inlet end of the zero electrode determines that there must be a cause The turbulent flow of water will cause the water flow into the zero electrode per unit time to be inconsistent.

Similar to this situation, the electric boilers provided by the patent CN108151298A and the patent CN110068002A also have the situation that the resistance between the three pairs of phase electrodes and the zero electrode is inconsistent due to the turbulent flow of water.
