Safe anti-freezing and anti-blocking technological method and safe anti-freezing and anti-blocking technological device for heating furnaces

Abstract

The invention discloses a safe anti-freezing and anti-blocking technological system and a safe anti-freezing and anti-blocking technological device for heating furnaces, and belongs to the technical field of oil field ground engineering. The safe anti-freezing and anti-blocking technological device is characterized in that an inlet pipeline is connected with a first inlet valve and an eleventh control valve, the other end of the first inlet valve is connected with a second inlet valve, a third inlet valve and a twelfth control valve, the other end of each of the second inlet valve and the third inlet valve is connected with a heating furnace II, an outlet pipeline of the heating furnace II is respectively connected with a fourth outlet valve and a fifth outlet valve, the other end of each of the fourth outlet valve and the fifth outlet valve is respectively connected with a thirteenth control valve and a fourteenth outlet control valve, the other end of the twelfth control valve is connected with the other end of the thirteenth control valve, an outlet pipeline of a heating furnace I is respectively connected with an eighth outlet valve and a ninth outlet valve, the other end of the eighth outlet valve and the other end of the ninth outlet valve are connected with the other end of the fourteenth outlet control valve and a tenth control valve, and the other end of the tenth control valve is connected with the other end of the eleventh control valve. According to the safe anti-freezing and anti-blocking technological method and the safe anti-freezing and anti-blocking technological device for the heating furnaces, disclosed by the invention, normal dehydration on crude oil after heating is ensured.

Description

technical field [0001] The invention relates to a process method and device for safely preventing freezing and blocking of a heating furnace, and belongs to the technical field of oil field surface engineering. Background technique [0002] The crude oil heating equipment of the centralized processing station in the Shixi oilfield operation area adopts two 5000W tubular heating furnaces, which are designed in parallel during construction, that is, one is used and the other is used. It is not easy to spare the furnace during the actual production process in winter The thermal insulation and commissioning of the oil will bring difficulties to the heating of crude oil in winter and the normal dehydration of crude oil, resulting in unqualified product quality, affecting the diplomatic work of crude oil, and bringing hidden dangers to safe production. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention provides a proc...
