Description

The claimed technical solution relates to the field of electrical heaters designed for heating and evaporation of water in the expenditure mode and in the composition of closed water and steam and water circuits.

"The level of technology." Known electrode water heater (abstract of the application for invention RU 95114849 from 09/04/95, publ. BI 08/20/1997, F24H 1/20), containing electrodes that are "installed at an equal distance with the formation of through channels and are located phases alternately, the electrode water heater, providing enhanced safety, works as follows: heated water flows through the inlet, and, passing through the electrodes, is heated as the working medium of the resistance furnace; The movement of the working medium can be carried out due to the pressure of the hydraulic network (discharge mode) or due to natural circulation (in closed loop mode), DIFFERING by the fact that, to ensure the safety of the electrode water heater and equalize the distribution of potentials, the through electrodes are installed at equal distances with the formation of through channels and arranged in electrical phases are alternately made movable in the plane of rotation, and extra zero electrodes are additionally installed, located along tricheskih phases symmetrically, outside the heating unit.

The plane of rotation coincides with the plane of the electrode.

The study of electrode systems is of great importance in connection with the increase in the field of application of these systems for solving production problems.

The safety of electrode water heaters is given much attention.

From the previously considered examples, the proposed technical solution differs by the extreme location of the additionally installed “zero” electrodes.

The implementation of the invention is performed in such a way that the electrodes, which are installed at an equal distance with the formation of through channels and are alternately arranged in electric phases, are made movable in the plane of rotation outside the heating unit (see the figure).

The implementation of the invention is performed by the extreme location of the zero electrodes, which are installed at an equal distance with the formation of through channels arranged alternately in the electrical phases, which are additionally installed outside the heating unit.

The specified extreme location additionally installed at an equal distance with the formation of through channels outside the heating unit of zero electrodes in electrical phases symmetrically ensures the safety of the installation.

You can make a conclusion about the compliance of the proposed technical solution the criterion of "novelty."

A comparative analysis of the claimed invention also showed that the use of these components in the totality of signs provides a new property - the safety of the installation, due to the distribution of potentials in a conductive medium.

Thus, we can conclude that the proposed technical solutions according to the criterion of "inventive step".

The figure shows a diagram of an electrode water heater: 1, 2 is a housing, 3 is an extreme zero electrode, 4, 5 is an insulator.

Claims (1)

Electrode water heater containing electrodes that are installed at equal distances with the formation of through channels and are alternately arranged in electrical phases, characterized in that the extreme zero electrodes outside the heating unit are additionally installed.
