The inlet pipe is connected to the first inlet valve and the eleventh control valve, the other end of the first inlet valve is connected to the second inlet valve, the third inlet valve and the twelfth control valve, the other end of the second inlet valve and the third inlet valve are Connect to 2# heating furnace, the outlet pipes of 2# heating furnace are respectively connected to the fourth outlet valve and the fifth outlet valve, and the other ends of the fourth outlet valve and the fifth outlet valve are connected to the thirteenth control valve and the fourteenth outlet control valve , the other end of the twelfth control valve is connected to the other end of the thirteenth control valve, the outlet pipe of 1# heating furnace is respectively connected to the eighth outlet valve, the ninth outlet valve, the other end of the eighth outlet valve, the ninth outlet valve The other end of the outlet control valve is connected to the other end of the fourteenth outlet control valve and the tenth control valve, and the other end of the tenth control valve is connected to the other end of the eleventh control valve. The invention guarantees the normal dehydration of crude oil after heating and provides guarantee.

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...
