Description

Technical Field

[0001] This utility model relates to the field of oil extraction equipment technology, specifically, it is a heating furnace. Background Technology

[0002] In existing technology, the heating furnace includes a U-shaped fire tube, a horizontal oil inlet, a fixed flue outlet, and an oil-water separation chamber. Crude oil enters the tank through the horizontal inlet and flows directly to the U-shaped fire tube for heating. Most of the evaporated petroleum gas is used as fuel to supply the fire tube or enters downstream processes, while the oil-water mixture is discharged after gravity separation. This type of heating furnace lacks an isolation structure, allowing the oil-water mixture to flow freely within the tank, resulting in an unclear oil-water interface, a water content exceeding 15% in the oil, and easy exposure of the heating area to gas. The fixed flue outlet is prone to blockage and overpressure, increasing the risk of explosion. It also requires frequent manual disassembly and cleaning, resulting in a short maintenance cycle.

[0003] Therefore, existing technologies need to be improved and enhanced. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a heating furnace with low water content in the oil and to prevent overpressure accidents caused by flue blockage.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A heating furnace includes a cylindrical body, a U-shaped heating tube disposed inside the cylindrical body, and a longitudinal baffle. The heating tube has a fire tube inlet and a flue outlet located outside the cylindrical body. The flue outlet is provided with two flanges and a rupture disc between the two flanges. The longitudinal baffle divides the cylindrical body into a heating zone and an oil collection zone, and the heating tube is located in the heating zone.

[0006] As a further embodiment of this utility model, a chimney is provided at the flue outlet, and a chimney cap is provided at the top of the chimney.

[0007] As a further embodiment of this invention, a lightning rod is provided on the chimney cap.

[0008] As a further embodiment of this utility model, the cylinder is provided with a crude oil inlet pipe, the crude oil inlet pipe having a crude oil inlet located outside the cylinder and a crude oil outlet located inside the cylinder, and the crude oil outlet extending upward into the cylinder with an oil outlet pipe.

[0009] As a further embodiment of this utility model, an oil distribution cap is provided at the top of the oil outlet pipe.

[0010] As a further embodiment of this utility model, a gas outlet pipe is provided on the top wall of the cylinder corresponding to the heating zone, a circular end cap is provided at the top of the gas outlet pipe, and a Z-shaped gas branch pipe is connected to the side wall of the gas outlet pipe, the gas branch pipe having a gas outlet.

[0011] As a further embodiment of this invention, a mist eliminator is provided inside the gas outlet pipe.

[0012] Compared with the prior art, the beneficial effects of this utility model are: Due to the aforementioned structural design, the cylinder is equipped with longitudinal baffles and heating pipes. The longitudinal baffles divide the cylinder into a heating zone and an oil collection zone. After the heating pipes heat the oil-water mixture, the lower layer of water is discharged through the drain outlet, and the upper layer of oil overflows through the longitudinal baffles and collects in the oil collection zone, thereby improving the efficiency of natural oil-water stratification and reducing the water content in the oil to ≤5%. At the same time, the longitudinal baffles ensure that the heating pipes are always immersed in the liquid, eliminating the risk of deflagration. The flue outlet of the heating pipes is equipped with two flanges and a rupture disc between the two flanges. The rupture disc automatically bursts to release pressure when there is overpressure, avoiding explosion accidents. At the same time, the flanges are designed to be removable, which facilitates flue cleaning and reduces downtime losses. Attached Figure Description

The flue outlet 1012 is provided with two flanges 1013 and a rupture disc 1014 between the two flanges 1013. The longitudinal baffle 102 divides the cylindrical body into a heating zone and an oil collection zone. The heating tube 101 is located within the heating zone. Through the above structural design, the cylindrical body is provided with the longitudinal baffle 102 and the heating tube 101, and the longitudinal baffle 102 divides the cylindrical body into a heating zone and an oil collection zone. In the oil collection area and the oil-water mixing area, the heating tube 101 heats the oil-water mixture, and the lower layer of water is discharged through the drain port of the cylinder, while the upper layer of oil overflows through the longitudinal baffle and collects in the oil collection area, thereby improving the efficiency of natural oil-water stratification and reducing the water content in the oil to ≤5%. At the same time, the longitudinal baffle 102 ensures that the heating tube 101 is always immersed in the liquid, eliminating the risk of deflagration. The flue outlet of the heating tube 101 is equipped with two flanges 1013 and a rupture disc 1014 between the two flanges 1013. The rupture disc is a flat rupture disc, which automatically bursts to release pressure when overpressure occurs, avoiding explosion accidents. At the same time, the flanges are designed to be detachable, which facilitates flue cleaning and reduces downtime losses.

[0019] Specifically, a chimney 1015 is provided at the flue outlet 1012, and a chimney cap 1016 is provided at the top of the chimney 1015 to prevent foreign objects from entering the chimney through the open chimney opening, causing blockage or fire hazards; a lightning rod 1017 is provided on the chimney cap 1016 to prevent lightning from directly hitting the chimney cap or the chimney body.

[0020] Specifically, the cylinder 100 is provided with an oil inlet pipe 103, which has an oil inlet 1031 located outside the cylinder 100 and an oil outlet 1032 located inside the cylinder. The oil outlet 1032 extends upward into the cylinder to form an oil outlet pipe 1033, changing the horizontally set oil inlet in the prior art to a vertically upward straight pipe. When oil and gas enter the cylinder, gravity separation is achieved in the vertical branch pipe, that is, the gas moves upward and the liquid falls. An oil diffuser cap 1034 is provided at the top of the oil outlet pipe 1033 to disperse the oil flow.

[0021] Specifically, a gas outlet pipe 104 is provided on the top wall of the cylinder 100 corresponding to the heating zone.
