Description
Technical field
The utility model relates to oil field CO
2the displacement of reservoir oil with bury Above Ground Technology field, be specifically related to liquid CO
2be transported to the supercharging after objective by tank vehicles to unload and storage tank storage.
Background technique
At oil field CO
2the displacement of reservoir oil with bury field, early stage small-scale pilot test usually adopt road transporting mode, i.e. liquid CO
2be transported to Oil Field by tank vehicles, and then unload and enter CO
2storage tank stores for subsequent use.Due to CO
2special nature, the change of temperature, pressure all can cause CO
2gasification, the direct result after gasification is exactly CO
2pressure of storage tank raises, thus causes the liquid CO in tank car storage tank
2the difficulty of unloading because tank car internal pressure is not enough, be embodied in length consuming time of unloading, in tank car storage tank, residual capacity is many, CO
2even be difficult to be pumped in storage tank go.
Summary of the invention
The utility model aims to provide one can increase tank car storage tank pressure, improves the supercharging speed-raising type CO of efficiency of unloading
2tank car discharge system.
The utility model supercharging speed-raising type CO
2tank car discharge system, comprises liquid CO
2tank car, is provided with liquid CO in tank car
2storage tank, is characterized in that liquid CO
2storage tank is provided with liquid phase output pipe and gas phase intake line; Wherein liquid phase output pipe is divided into left and right two-way, left and CO
2storage tank is connected, and right wing is connected with the entrance of water-bath type heater; The outlet of water-bath type heater is connected with gas phase intake line.
Preferably, liquid CO
2be provided with pressure-detecting device in storage tank, the right wing of liquid phase output pipe is provided with valve.
More preferably, described pressure-detecting device is pressure transmitter, and described valve is solenoid valve.
Or further preferably, gas phase intake line is provided with safety valve and check valve.
Supercharging speed-raising type CO described in the utility model
2tank car discharge system, overcomes existing CO
2tank car storage tank is unloaded flow process length consuming time and the incomplete shortcoming of discharging, improves CO by heating water bath
2tank car storage tank pressure, working efficiency high, clean environment firendly during use and sustainablely carry out operation.

Embodiment
Embodiment one
As shown in the figure, supercharging speed-raising type CO of the present utility model
2tank car discharge system, comprises liquid CO
2tank car, is provided with liquid CO in tank car
2storage tank 1, liquid CO
2storage tank 1 is provided with liquid phase output pipe 8 and gas phase intake line 10.
Liquid phase output pipe 8 is divided into left and right two-way, and left directly connects CO
2storage tank, normally unloads to storage tank.Right wing connects water-bath type heater 11.The outlet of water-bath type heater 11 is connected with gas phase intake line 10.Water-bath type heater 11 is by liquid towards CO
2heating, by the CO after gasification
2turn back to liquid CO
2storage tank 1 gas-phase space is liquid CO
2storage tank 1 supercharging.
Liquid CO
2storage tank 1 is provided with pressure transmitter 2, and tank car is provided with solenoid valve 7 to the liquid phase output pipe 8 of water-bath type heater 11, when pressure transmitter 2 detects liquid CO
2when in storage tank 1, pressure is lower than setting value, solenoid valve 7 is opened automatically, and liquid carbon dioxide is heated by pipeline.
Water-bath type heater 11 passes through gas phase intake line 10 by gaseous state CO
2return liquid CO
2in storage tank 1.Gas phase intake line 10 is provided with safety valve 9 and check valve 4.Safety valve 9 pairs of pipelines play a protective role, when water-bath type heater 11 exports gaseous state CO
2exceed critical value, make loine pressure too high, safety valve 9 take-off pressure release automatically.Check valve 4 is used for preventing liquid CO
2storage tank 1 overpressure, reverse backflow is to water-bath type heater 11.
Water-bath type heater 11 can adopt electric heating, and is provided with heater control cabinet 12, realizes the setting of bath temperature, and this water-bath type heater has temperature automatically controlled function.
During use, first add water appropriate location in water-bath type heater 11, setting outlet temperature.Then solenoid valve 7 cracking pressure is set.
Unload in process, as liquid CO
2storage tank 1 Pressure Drop is to setting value, and solenoid valve 7 is opened automatically, liquid CO
2enter water-bath type heater 11 by pipeline to heat, gaseous state CO
2return liquid CO
2storage tank 1 is its pressurization.Time more than pressure recover to setting value, solenoid valve 7 cuts out automatically.
