Problems solved by technology

However, the voltage level of the resistance molten salt heater is relatively small, and the heat exchange area and number of the electric heating tubes increase with the increase of the heating power, and the volume of the heater also increases with the increase of the heating power. As a result, the molten salt electric heater of a large-scale energy storage system occupies a very large area, and the construction investment cost is relatively high

Abstract

The invention discloses an electrode type molten salt heater. The electrode type molten salt heater is characterized by comprising an electrode bracket, control shields, three-phase electrodes, neutral electrodes, a power interface, a screw, a movable type connector and a supporting plate which is positioned in an opening of a lower semi-elliptical end socket, wherein the three-phase electrodes are arranged on the inner part of a barrel body; the three-phase electrodes are distributed in the form of a regular triangle inside the barrel body and are supported by the electrode bracket; the upper parts of the three-phase electrodes are connected to the power interface; the circular-ring-shaped neutral electrodes cover the three-phase electrodes; the control shields are arranged between the three-phase electrodes and the neutral electrodes; and a motor drives the screw, the movable type connector and the control shields to rotate or lift, so that an opposite area between the three-phase electrodes and the neutral electrodes is changed. The electrode type molten salt heater has the advantages of being high in heating efficiency, compact in structure, small in floor space, excellent in safety performance and the like.

Description

technical field [0001] The invention belongs to the field of molten salt heating equipment, in particular to an electrode type molten salt heater. Background technique [0002] As a heat transfer and heat storage medium with excellent performance, molten salt has the advantages of high service temperature, high thermal stability, high specific heat capacity, high convective heat transfer coefficient, low viscosity, low saturated vapor pressure and low price, and is widely used Applied in the field of heat storage technology. Chinese patent document CN103836703A, published on June 4, 2014, proposes a molten salt regenerative electric heating centralized heating system, in which the molten salt is heated by a molten salt electric heater and stored in a thermal The salt tank sends molten salt to the molten salt-water heat exchanger during the peak period of electricity consumption during the day, heats the municipal heating circulating water, and generates hot water for heatin...
