Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of heat exchange, in particular to an integrated high-efficiency intelligent heat exchange device for oilfield stations. BACKGROUND

[0002] After crude oil enters the oilfield station through the gathering pipeline, it is first separated by a gas-liquid separator, and then dehydrated by heating. In the heating and dehydration stage, the equipment used by the oilfield station to heat the crude oil is a heat exchanger, which is a device that exchanges heat with hot water or steam. The heat exchanger uses hot water or steam as a heat medium, and the oilfield station generally uses hot water for heat exchange. At present, most of the heat exchangers in the station use manual stop valves, and then the heat exchange effect is observed by observing the temperature of the heat medium and the cold medium at the inlet and outlet of the heat exchanger. If the temperature of the cold medium outlet decreases, the opening of the stop valve is increased to increase the flow of the heat medium and increase the temperature of the cold medium outlet. If the temperature of the cold medium outlet is too high, the opening of the stop valve is reduced to reduce the flow of the heat medium and reduce the temperature of the cold medium outlet.

[0003] Manual control of the stop valve requires a lot of time and labor, which is inconvenient. When the crude oil enters the shell side of the heat exchanger for heat exchange, the flow type heat exchange is easy to cause the heat exchange efficiency of the crude oil to be not high, and increasing the contact time of the crude oil with the heat medium can fully exchange heat, but it will reduce the overall efficiency.
