Double-layer columnar heat transfer device, pipeline for heat transfer of fluid substance and method

Abstract

The invention discloses a double-layer columnar heat transfer device, a pipeline for heat transfer of a fluid substance and a method and belongs to a pipeline heating technology. The double-layer columnar heat transfer device comprises a heat conductive columnar casing 1 and partition boards 2, and an inner cavity of the heat conductive columnar casing 1 is closed space and divided by the partition boards 2 into a plurality of cavities 4 parallel to the axial direction of the heat conductive columnar casing; the cavities 4 are filled with a working medium; a plurality of microfins 3 made of a heat conduction material are arranged on the inner walls of the cavities 4 in sequence, arrayed capillary microgrooves 9 are formed between the adjacent microfins 3 and are arranged in a mode which is beneficial to reduction of resistance received by the working medium flowing in the cavities 4; columnar heat pipes are further inserted in the cavities, and arrayed microfins are arranged on the inner walls of the columnar heat pipes. The invention further provides the pipeline based on the columnar heat transfer device and the heating method.

Description

technical field [0001] The invention relates to pipeline heating technology, in particular to a double-layer columnar heat transfer device, a pipeline and a method for fluid material heat transfer. Background technique [0002] In many industrial fields, on the one hand, there is a demand for heating or heat exchange of fluid substances such as oil, water, and gas. On the other hand, a lot of industrial waste heat will be generated, which can be recycled to save energy. Heat transfer equipment for these two needs generally needs to be relatively large, capable of smooth heat transfer and fluid delivery, and the temperature is stable within a certain range during the heat transfer process to ensure safety. [0003] For example, during the process of transporting viscous oil from the underground to the ground, the oil will become very thick at the ground temperature and it is difficult to effectively transport it. Therefore, it is necessary to heat the pipeline at the wellhea...

AI Technical Summary

Problems solved by technology

The reserves of natural gas are limited, and the consumption of natural gas in the process of oil extraction is neither economical nor long-term for the country and the people, and is not conducive to energy conservation and emission reduction

3. Since the place where the water jacket furnace heats the oil pipeline is at the ground engineering point of oil exploitation, natural gas is used as the fuel of the water jacket furnace at the ground engineering point of oil exploitation, and very strict safety management methods must be adopted

However, inserting a heat pipe into a water heater cannot solve the problems of uneven heating of crude oil in the oil pipeline, safety management and shortage of fuel for the heating furnace, etc.

[0007] In summary, the current oil pipeline heating technology has the above defects, and no effective solutions or solutions have been seen
