Abstract

The invention provides a crude oil heating system with a heat storage function. The crude oil heating system comprises a solar collector, a heat medium storage tank and a crude oil heat exchanger. The crude oil heat exchanger comprises a heat exchange unit and a heat storage unit. An outlet of the heat medium storage tank is divided into two paths, one path of the outlet of the heat medium storage tank is connected with an inlet of the solar collector through a pipeline, an outlet of the solar collector is connected with a heat medium inlet of the crude oil heat exchanger through a pipeline, and a heat medium outlet of the crude oil heat exchanger is connected with an inlet of the heat medium storage tank; and the other path of the outlet of the heat medium storage tank is connected with a heat medium inlet of a heat storage unit through a pipeline, and a heat medium outlet of the heat storage unit is connected with the heat medium inlet of the crude oil heat exchanger through a pipeline. The invention further provides a crude oil heating method with the heat storage function. By the adoption of the crude oil heating system, the utilization efficiency of solar heat can be increased, and meanwhile the output stability of the solar heat is improved.

Description

technical field [0001] The invention relates to the field of solar thermal utilization, in particular to the application of solar thermal utilization and heat storage in the field of crude oil heating, mainly inventing a solar heating crude oil equipment and process with heat storage function. Background technique [0002] my country's crude oil has the characteristics of high condensation and high viscosity. At the same time, with the deepening of mining, the proportion of heavy oil reserves will increase and the water content will increase. The energy consumption in the process of mining, gathering and transportation is huge. On the other hand, my country has sufficient sunlight resources, and areas with sunshine hours of more than 2,200 hours, such as Inner Mongolia, Xinjiang, and Gansu, account for more than two-thirds of the country's land area. The energy received by solar radiation is equivalent to the power generation of tens of thousands of Three Gorges Projects or ...
