Based on above-mentioned technical scheme, the check valve guarantees that the oil gas in the white oil jar discharges to the system along the check valve direction of laying, avoids the interior oil gas backward flow of system to in the white oil jar. The purpose of setting up the gate valve is that this equipment white oil jar of being convenient for can amputate alone, and the gate valve is opened under the normal condition, uses the white oil jar to be in and puts into operation the state, guarantees that oil gas in time effectively discharges, uses with the cooperation of individual valve, makes oil gas discharge to torch system, avoids torch system interior oil gas reverse scurrying into the quick-witted pump white oil jar and seals, damages equipment.
Further, the discharge line includes an upper inclined section, a horizontal section, a vertical section, and a lower inclined section; the last slope section of emission pipeline connects at the white oil tank top, and the last slope section tip extends to the piping lane bottom along the horizontal direction and forms the horizontal segment, and the horizontal segment is terminal vertically upwards arranges to the high torch house steward that goes out, forms vertical section, and the slope of vertical section tip is connected to torch house steward downwards, forms the section that slopes down.
Based on the technical scheme, the flow resistance of the exhaust gas can be reduced by the upper inclined section; the horizontal section is excessively connected with the pipe section and is connected with the upper inclined section and the vertical section. A vertical section: the main pipe of the flare system is arranged at the high point of the device pipe gallery, a vertical pipeline needs to be arranged, and the height of the main pipe of the flare system is 500mm higher than that of the main pipe of the flare; a lower inclined pipe section: are connected to the manifold segments.
Further, the vertical height of the upper inclined section of the discharge pipeline is 500-700 mm.
Preferably, the vertical height of the upper inclined section of the discharge line is greater than 500mm, preferably 700mm, and the upper inclined section can reduce the flow resistance of oil and gas.
Further, the vertical section of the discharge line is at least 500mm above the flare header.
Preferably, the vertical section of the discharge pipeline is 500mm higher than the flare header pipe, so that the oil gas condensate and the sweeping steam condensate in the flare header pipe are prevented from flowing back to the sealed white oil tank.
Further, the lower inclined section of the discharge line is connected at the upper portion of the flare header at a 45 ° orientation. The oil gas of the white oil tank is ensured to be smoothly discharged into the torch system, and the phenomenon that the pipeline condensate flows back to the white oil tank is effectively avoided.
Further, the gate valve is installed at the head end of the vertical section of the discharge line, and the gate valve is provided with an internal screw thread, and the gate valve is connected to the discharge line through the internal screw thread.
Further, the check valve is installed at a lower inclined section of the discharge line.
The invention has the beneficial effects that: the oil gas discharged by the pump white oil tank is introduced into the torch system, the oil gas can be recovered to a fuel gas system in a centralized manner, the pressure channeling influence is eliminated, and the shaft end sealing is effectively ensured.

Detailed Description
In order to make the structure and function of the present invention clearer, the technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention.
Referring to the attached drawing 1, the closed discharge system of the machine pump sealing white oil tank is characterized in that a short section 2 is arranged at the top of the machine pump white oil tank 1, a check valve 3 facing the system and a gate valve 4 with internal screw threads are arranged on the short section, a discharge pipeline 4 is arranged along the direction of the short section at the top of the white oil tank, a mounted discharge pipeline 6 is connected to the gate valve 4 through screw threads, the discharge pipeline comprises an upper inclined section 6.1, a horizontal section 6.2, a vertical section 6.3 and a lower inclined section 6.4, the upper inclined section 6.1 of the discharge pipeline is connected to the top of the white oil tank 1, the vertical height of the upper inclined section is 700mm away from the top of the white oil tank, the pipeline starts to be horizontally arranged and leads to the bottom of a pipe gallery to form the horizontal section 6.2, then the pipeline is vertically arranged upwards to form the vertical section 6.3, and a flare main pipe 5 is inserted into the upper.
