Description

Technical Field

[0001] The utility model relates to the technical field of electric heating devices, in particular to a molten salt electric heating device. Background Art

[0002] The heating of the molten salt tank is generally based on the steam produced by the plant. Under normal operation, it can meet the minimum temperature requirement of 160℃ for the molten salt tank. When the plant is undergoing a major overhaul, the steam is stopped at the same time, and the heat source for the molten salt tank cannot be guaranteed. As the temperature drops, the molten salt begins to solidify. It is necessary to wait until the molten salt in the molten salt tank is completely melted when the steam is operating normally before the start-up procedure can be carried out, which seriously delays the start-up date and also affects the normal start-up of the alkylation unit, posing a hidden danger to whether the unit can be started on schedule. Therefore, we propose a molten salt electric heating device. Utility Model Content
