Corrugated plate molten salt heat storing and heat supplying system and working method thereof

Abstract

The invention discloses a corrugated plate molten salt heat storing and heat supplying system and a working method thereof. The corrugated plate molten salt heat storing and heat supplying system comprises a heat conduction oil heating and heat storing system, a heat supplying system, a central processing unit and molten salt heat storing devices which are internally filled with molten salt, the central processing unit is correspondingly connected with the heat supplying system and the heat conduction oil heating and heat storing system, the plurality of molten salt heat storing devices are arranged in a heat storing tank of the heat conduction oil heating and heat storing system, the heat supplying system is used for performing heat exchange on a heat storage medium in the heat storing tank to achieve stable control and output of an outlet working condition, and the central processing unit is used for achieving automatic control. According to the corrugated plate molten salt heat storing and heat supplying system and the working method thereof, a technology of a heat storing type system with heating and heat storing performed through off-peak electricity and the molten salt and heat releasing performed at peak is utilized to complete peak shaving and valley filling in the aspect of the power, so that the system equipment quantity is greatly reduced, the operation is more stable, and automatic control can be realized.

Description

Technical field [0001] The invention belongs to the technical field of heating systems, and specifically relates to a corrugated plate molten salt heat storage heating system and a working method thereof. Background technique [0002] With the development of the national economy and the continuous improvement of people's living standards, my country's energy demand structure has undergone major changes. On the one hand, there is insufficient peak power, and on the other hand, there are problems such as excessive peak-to-valley difference. The emergence of these contradictions has restricted the development of the national economy. At the same time, high-temperature heat storage technology realizes the storage and release of heat energy through heat storage materials, and can also effectively solve the phenomenon of energy demand and supply mismatch. However, there are still some technical problems in this technology, which restrict its development. In summary, there are mainly t...

AI Technical Summary

Problems solved by technology

[0005] (2) The complexity of the heat conduction oil heating system makes it difficult to realize automatic control when the design requirements are met

[0006] Due to the large number of equipment in the heat transfer oil heating system and unforeseen failures during operation, there are great difficulties in the automatic control of the equipment

[0007] (3) The cumbersomeness of the traditional molten salt heating system requires a large amount of equipment to meet the design requirements

[0009] (4) The start-up process of the traditional molten salt heating system is complicated

[0010] (5) In the traditional molten salt heating system, after the molten salt is melted for the first time, it cannot be solidified again, otherwise it will consume a lot of heat and melt the molten salt again, resulting in waste of heat

[0011] (6) The automation control degree of the traditional molten salt heating system is low
