Heat storage and heat supply system heating heat conduction oil through off-peak electricity and coupling heat pipe heat exchanger

Abstract

The invention discloses a heat storage and heat supply system heating heat conduction oil through off-peak electricity and coupling a heat pipe heat exchanger. The system comprises a heat conduction oil heating and heat storage system, a heat supply system and a central processing unit; and the central processing unit is connected with the heat supply system and the heat conduction oil heating andheat storage system, the heat conduction oil heating and heat storage system comprises a heat storage tank, the heat pipe heat exchanger is arranged in the heat storage tank, the heat pipe heat exchanger is arranged in heat conduction oil, connected with the heat supply system and used for carrying out heat exchange on a heat storage medium in the heat storage tank to achieve stable control and output of an outlet working condition, and the central processing unit is used for realizing automatic control. According to the system, through effective combination with an existing energy configuration problem in China, a heat storage type system effectively utilizing the off-peak electricity for heating, heat storage and peak heat releasing is technically analyzed, and peak shifting and valleyfilling on electric power is completed.

Description

technical field [0001] The invention belongs to the technical field of heat transfer oil heat storage, and in particular relates to a heat storage and heat supply system for electric heating of heat transfer oil coupled with a heat pipe heat exchanger in valleys. Background technique [0002] With the development of the national economy and the continuous improvement of people's living standards, great changes have taken place in the structure of electricity consumption in my country, especially in coastal areas. On the one hand, there are problems such as insufficient peak power, and on the other hand, there are problems such as excessive peak-to-valley differences. The emergence of these contradictions restricts the development of the national economy. For this reason, on the one hand, the power industry department has accelerated the pace of power construction, and on the other hand, it has proposed the policy of "shaving peaks and filling valleys" to make full use of pow...

Problems solved by technology

In the normal operation stage, the heat transfer oil circulates among the circulation pump, electric heater, heat user, oil-gas separator, and circulation pump to transfer the heat of the electric heater to the heat user. At this stage, the heat transfer oil does not pass through the high-level tank, and the heat transfer oil heating system is complicated. sex
