Description
Technical field
The utility model relates to a kind of Unloading Device of tank car, particularly a kind of emptying obturator of tank car.
Background technology
At present, the jar mouth of tank car emptying time slot roof gas-phase space directly opens wide to atmosphere, and the gas that volatilizes in the tank car will directly be disposed in the atmosphere, and promptly there is potential safety hazard again in foul air.Especially the crude oil process of unloading need be through the steam jacket heating, and its dusty gas volatile quantity is bigger.
The utility model content
Not enough to prior art, the special emptying obturator that proposes the tank car of a kind of environmental protection, safety of the utility model.
The utility model solves the technical scheme that its technical matters adopted: a kind of emptying obturator of tank car; Comprise airtight assembly of tank car and tidal air assembly; The jar that the airtight assembly of said tank car is placed on said tank car mouthful is gone up and can the jar of said tank car is mouthful airtight, and said tidal air assembly is communicated with the top gas-phase space of said tank car and can makes the interior pressure self-balancing of said tank car; After said tidal air assembly, also be provided with processing equipment, said tidal air assembly is communicated with through pipeline with said processing equipment.
Said processing equipment is set after said tidal air assembly to be meant after gas that said tank car is breathed out is through said tidal air assembly, to discharge and to get into processing equipment and handle; The jar mouthful gas of discharging from tank car directly is disposed to the drawback of atmosphere in the prior art thereby overcome, and the oil gas of breathing out in the tank car is recycled and then energy savings.
The airtight assembly of said tank car comprises revoliving arm and seal cover cap; Said seal cover cap removably is placed on the jar mouthful of said tank car and with the Jar opening sealer of said tank car; Said revoliving arm can be pressed on said seal cover cap the jar mouth of said tank car, and said tidal air assembly is communicated with through said revoliving arm ventilation with the top gas-phase space of said tank car.
Said tidal air assembly comprises getter assembly and expiration assembly; Said getter assembly comprises aspirating air pipe and the self-supporting control cock and the boiler check valve that are communicated with by order before and after the said aspirating air pipe, and the gas vent of said boiler check valve is communicated with through said aspirating air pipe with the top gas-phase space of said tank car; Said expiration assembly comprises expiration pipeline and the flame trap and the outlet valve that are communicated with by order before and after the said expiration pipeline; And the gas feed of said flame trap is communicated with through said expiration pipeline with the top gas-phase space of said tank car, is communicated with said processing equipment through pipeline after the said outlet valve.In the emptying process; When the gas-phase space differential pressure is low to moderate setting value in the tank car; Self-supporting control cock self-opening; Unreactable gas passes through self-supporting control cock and boiler check valve successively through aspirating air pipe, and unreactable gas entering tank car is interior to the tank car tonifying Qi then, and gas-phase space pressure is higher than setting value self-supporting control cock SELF CL in tank car.Wherein, boiler check valve can prevent that gas from falling to go here and there.When gas-phase space pressure rises to setting value in the tank car in the emptying process; Outlet valve is opened automatically; The gas of breathing out in the tank car passes through flame trap and outlet valve successively through the expiration pipeline; The gas of breathing out then gets into processing equipment to carry out oil gas and handles and be recycled, in tank car gas-phase space pressure fall after rise to setting value with interior outlet valve SELF CL.Wherein, flame trap realizes that flame isolates, and can prevent that flame from going here and there mutually.
Said self-supporting control cock is a nitrogen envelope valve.
Said outlet valve is for letting out the nitrogen valve.
The unreactable gas gas transmission pipeline net work also was set before said self-supporting control cock, and said unreactable gas gas transmission pipeline net work is communicated with the admission port of said self-supporting control cock through said aspirating air pipe.
