Abstract
The utility model relates to a delivery pipeline control device used for a liquefied gas desulfurization system, which comprises a liquefied gas inlet pipe, a gas inlet valve, a liquefied gas buffer tank, an electric pump front valve, an electric pump, an electric pump rear valve, a delivery valve, a desulfurizing tower valve, a pipeline and a desulfurizing tower. A bridging pipeline is arranged between the liquefied gas inlet pipe and the rear end of the electric pump rear valve, and bridging valves are arranged at the front and the rear ends of the bridging pipeline respectively. The utility model has the advantages of simple structure, low electric energy consumption and low pipeline loss.
Description
Technical field
The utility model relates to desulfuration of liquefied gas systems technology field, relates to the transport pipe control device in a kind of desulfuration of liquefied gas system specifically.
Background technology
Liquefied gas in the desulfuration of liquefied gas system is at first to enter the liquefied refinery gas surge tank, export the desulfuration of liquefied gas tower to through liquefied gas motor-mount pump supply power then and carry out desulfuration of liquefied gas, this type of desulfuration of liquefied gas system at gas pressure hour, need power to replenish, and when gas pressure is higher, the work of liquefied gas motor-mount pump will cause waste of electric energy, has increased pipeline power consumption and production cost.
The utility model content
The purpose of this utility model is exactly the defective that exists at prior art, provide a kind of simple in structure, save electric energy and reduced transport pipe control device in the desulfuration of liquefied gas system of pipeline power consumption.
Its technical scheme is: comprise liquefied gas inlet pipe, air intake valve, liquefied gas surge tank, motor-mount pump early gate, motor-mount pump, motor-mount pump late gate, carry valve, thionizer valve, pipeline and thionizer, it is characterized in that: the rear end at liquefied gas inlet pipe and motor-mount pump late gate is connected with the cross-over connection pipeline, and the rear and front end of cross-over connection pipeline is separately installed with the cross-over connection valve.
Cooperate or thread fit for welding between described cross-over connection pipeline and the cross-over connection valve.
The utlity model has advantage simple in structure, that save electric energy and minimizing pipe loss.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
Embodiment
Elaborate by embodiment below in conjunction with Figure of description:
As shown in drawings,
The utility model comprises liquefied gas inlet pipe 1, air intake valve 2, liquefied gas surge tank 3, motor-mount pump early gate 4, motor-mount pump 5, motor-mount pump late gate 6, carries valve 7, thionizer valve 8, pipeline 13 and thionizer 9; Rear end at liquefied gas inlet pipe 1 and motor-mount pump late gate 6 is connected with cross-over connection pipeline 11, and the rear and front end of cross-over connection pipeline 11 is separately installed with cross-over connection valve 10,12.
Cooperate or thread fit for welding between cross-over connection pipeline 11 and the cross-over connection valve 10,12.
In the use, when the liquefied gas intake pressure is low, close cross-over connection valve 10,12, open air intake valve 2, motor-mount pump early gate 4, motor-mount pump late gate 6, carry valve 7 and thionizer valve 8, liquefied gas enters liquefied gas surge tank 3 by liquefied gas inlet pipe 1 through air intake valve 2, carry out power and replenish entering motor-mount pump 5 through motor-mount pump early gate 4, then through motor-mount pump late gate 6, carry valve 7, thionizer valve 8 and pipeline 13 to be transported to thionizer 9 to carry out desulfurization;
When the liquefied gas intake pressure is higher, at first closes air intake valve 2, motor-mount pump early gate 4, motor-mount pump late gate 6 and stop the work of motor-mount pump 5; Open cross-over connection valve 10,12 then, liquefied gas is transported to thionizer 9 by liquefied gas inlet pipe 1 through cross-over connection valve 10, cross-over connection pipeline 11, cross-over connection valve 12, conveying valve 7, thionizer valve 8 and pipeline 13 and carries out desulfurization, do not work owing to motor-mount pump 5 this moment, and got rid of liquefied gas surge tank 3, reach the purpose of saving electric energy and reducing pipe loss.
Claims (2)
1, the transport pipe control device in a kind of desulfuration of liquefied gas system, comprise liquefied gas inlet pipe, air intake valve, liquefied gas surge tank, motor-mount pump early gate, motor-mount pump, motor-mount pump late gate, carry valve, thionizer valve, pipeline and thionizer, it is characterized in that: the rear end at liquefied gas inlet pipe and motor-mount pump late gate is connected with the cross-over connection pipeline, and the rear and front end of cross-over connection pipeline is separately installed with the cross-over connection valve.
2, the transport pipe control device in the desulfuration of liquefied gas according to claim 1 system is characterized in that: cooperate or thread fit for welding between cross-over connection pipeline and the cross-over connection valve.
