Description
Technical Field
The utility model belongs to the technical field of energy storage, and particularly relates to a single-medium multiphase heat storage box.
Background
The gas heating furnace is the main energy consumption and waste gas emission equipment in the oil gas gathering and transportation process, and the number of heating furnaces of different types established in various large oil fields in China is tens of thousands at present, so that the energy consumption and the carbon emission are remarkable. With the increasingly strict requirements on energy and environmental protection worldwide and the realization of 'double carbon' targets in China, each large oil field adopts a multi-energy coupling heating mode such as an electric heating furnace, an air source heat pump, photo-thermal and the like to replace a fuel gas heating furnace, if the electric heating furnace and the air source heat pump are directly adopted to realize system heating without considering peak-valley electric difference, the system has high power consumption and poor economy, the solar heat collection day illumination time is limited, and non-illumination time heat collection cannot be realized, so that continuous low-cost heating of crude oil for 24 hours cannot be ensured. The multiphase heat accumulating box is one heat accumulating and releasing device with inorganic phase change material. The energy storage device can store energy converted or transmitted by various energy sources such as electric energy, heat energy and the like in a heat energy form and release the energy in need of the energy storage device so as to meet the energy requirements of different fields. For example, in the field of oilfield life, a multiphase heat storage tank may be used to store solar thermal energy for heating and hot water use, and in the field of oilfield production, it may be used to store high temperature thermal energy to support heating and steam generation during production. Therefore, the multiphase heat storage box has wide application prospect and plays an important role in realizing sustainable energy development.
The following problems generally exist in the prior composite heat accumulator structure (authorized bulletin number: CN 220250123U) in use:
1. Adopts an electrothermal structure, and has high energy consumption. First, in terms of energy waste, high energy consumption means that the heat storage tank needs to consume more electric energy when storing and releasing heat energy, which results in energy waste. In the case of limited resources, energy waste may exacerbate the problems of energy shortage and environment. Secondly, in terms of environmental pollution, electrical energy is typically obtained from fossil fuels or other non-renewable energy sources, and the energy conversion process thereof emits carbon dioxide and other pollutants from the isothermal chamber. Therefore, the high energy consumption of the electrothermal structure may indirectly cause problems such as environmental pollution, climate change and the like. Thirdly, in terms of economic cost increase, high energy consumption can lead to the increase of the operation cost of the heat storage box, including power consumption, maintenance cost and the like. This may burden the economy of an individual, business or institution and reduce its competitiveness. Fourth, in terms of sustainability problems, sustainability of the thermal storage tank is affected in the case of high energy consumption. Excessive consumption of energy may lead to exhaustion of energy and limit long-term availability of the heat storage tank, so that there is an urgent need for a heat storage tank that does not require electric heating.
2. The pressure in the heat storage box cannot be detected, and when the pressure is too high, the internal structure is possibly damaged, namely, in the aspect of safety risk, the too high internal pressure can cause safety accidents such as leakage and explosion of the heat storage box, and potential threats are caused to personal safety and property. Secondly, in the aspect of equipment damage, the excessive pressure can bring huge pressure load to the internal structure and equipment of the heat storage box, and the rupture or damage of parts such as a pipeline, a heat storage medium container, a valve and the like can be caused, so that the normal operation of the heat storage box is influenced. Thirdly, in the aspect of energy efficiency reduction, when the internal pressure of the heat storage box is too high, the flow performance of the heat storage medium can be influenced, so that the heat transfer efficiency is reduced, and the energy efficiency of the heat storage box is reduced.
