Concentrating solar heat collection crude oil heating system integrated with heat storing function

Abstract

The invention relates to a concentrating solar heat collection crude oil heating system integrated with a heat storing function. Crude oil is heated through a water bath jacket furnace and a heat exchanger, the water bath jacket furnace and the heat exchanger can be in a parallel connection or a series connection or in a connecting mode by combining the parallel connection and the series connection, the heat exchanger is respectively connected with a solar heat collection device, a buffer tank and a heat storing tank, the buffer tank is respectively connected with the heat exchanger, a circulating pump and a high-level oil storing tank, the solar heat collection device is respectively connected with the circulating pump, the heat exchanger and the buffer tank, the heat storing tank is respectively connected with the heat exchanger, the buffer tank and a low-level oil storing tank, the low-level oil storing tank is respectively connected with the heat storing tank and the high-level oil storing tank, and the high-level oil storing tank is respectively connected with the low-level oil storing tank, the circulating pump and the buffer tank. The concentrating solar heat collection crude oil heating system integrated with the heat storing function has the advantages that the concentrating solar energy can generate higher accumulated heat temperature to heat conduction oil which is used for heating the crude oil, meanwhile, the heat storing function is combined with the system, middle and high temperature solar energy utilization is realized, and photo-thermal efficiency of the whole system is increased.

Description

【Technical field】 [0001] The invention relates to the technical field of solar energy application, in particular to a concentrating solar heat collection heating crude oil system with integrated heat storage function. 【Background technique】 [0002] my country's crude oil generally has a high freezing point, high viscosity, and poor fluidity at room temperature. Therefore, crude oil must be heated during the extraction, processing, storage and transportation of crude oil. At least 20% of the energy consumption in the process of oil production, gathering and transportation in the oil field is used for heating and processing of crude oil. Energy consumption and serious environmental pollution problems, but also there are no small safety hazards. [0003] In order to solve the above problems, it has become a research hotspot in recent years to find energy-saving and clean heating methods to replace conventional oilfield exploitation and gathering methods. The patent with the ...

Problems solved by technology

Most of the widely used heat storage methods in the past use the sensible heat of the temperature change of the heat storage medium to store heat (such as hot water tanks, etc.), which have the disadvantages of large footprint, low heat storage capacity, and large heat storage temperature difference.

And there is no reasonable and effective system configuration and control for situations such as excess solar energy, lack of solar energy, excess crude oil, lack of crude oil, too high temperature of heat transfer oil, and too low temperature of heat transfer oil
