Concentrating type solar heat collecting and crude oil heating system

Abstract

The invention relates to a concentrating type solar heat collecting and crude oil heating system. Crude oil is heated through a water bath jacket furnace and a heat exchanger, the water bath jacket furnace and the heat exchanger are connected in parallel or in series parallel to be used in combination, a heat transfer oil inlet and a heat transfer oil outlet of the heat exchanger are connected with a solar heat collector and a buffer tank respectively, a heat transfer oil inlet and a heat transfer oil outlet of the buffer tank are connected with the heat exchanger and a circulating pump respectively, a heat transfer oil inlet and a heat transfer oil outlet of an oil supplementing tank are connected with an oil supplementing pump and the circulating pump respectively, a gasified heat transfer oil outlet of the buffer tank is connected with a gasified heat transfer oil inlet of the oil supplementing tank, a heat transfer oil inlet and a heat transfer oil outlet of the solar heat collector are connected with the circulating pump and the heat exchanger respectively, and the heat transfer oil outlet of the solar heat collector is also connected with the buffer tank. The system has the advantages that concentrating solar power can generate higher heat collecting temperature to have heat transfer oil heated and to be used for heating the crude oil, medium and high temperature utilization in the solar power is realized, and optical heat efficiency of the whole system is improved.

Description

【Technical field】 [0001] The invention relates to the technical field of solar energy application, in particular to a concentrating solar heat collection and heating crude oil system. 【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 publication number CN1654879 and t...

Problems solved by technology

[0004] However, in the existing technology, only non-concentrating solar collectors are used in the crude oil heating device with solar heat collection, and the heat collection temperature is relatively low.

The non-concentrating solar energy heating and transporting crude oil system usually heats the heat transfer medium water to about 80°C, and uses the sensible heat of the water to heat the crude oil. The thermal efficiency of the whole system is low, and the solar energy utilization rate is not high.

And there is no reasonable and effective system configuration and control for the situations of 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
