Accompanying drawing explanation
Fig. 1 is the structural representation of LNG storage tank of the present utility model.
Embodiment
In order to further illustrate principle of the present utility model and structure, now by reference to the accompanying drawings preferred embodiment of the present utility model is described in detail.
LNG storage tank is mainly used in the LNG Liquefied natural gas of splendid attire deep cooling, and is this LNG Liquefied natural gas cold insulation, prevents it from gasifying.In the filling process of LNG storage tank, conveniently judge whether storage tank is filled, usually, overflow height position (the highest liquid level) place of tank body is provided with spill pipe, and this spill pipe extends to tank body in tank body.
The utility model provides a kind of LNG storage tank can be positioned on the hull such as boats and ships or marine engineering equipment, and whether this LNG storage tank can this LNG storage tank of automated security monitor be full of.
As shown in Figure 1, LNG storage tank 10 of the present utility model comprises a tank body 11, the spill pipe from extraction in tank body 11, the overflow cylinder 13 be connected with this spill pipe and the temperature controlling device 14 be arranged on overflow cylinder 13.
Tank body 11 comprises interior tank body 111 and outer tank body 112, is filled with thermoinsulation material between interior tank body 111 and outer tank body 112.Interior tank body 111 for filling LNG liquid, but easily to gasify because of this LNG liquid and LNG liquid can produce certain rocking in tank body, therefore interior tank body 111 can not be full of, and is generally only charged to 90% of interior tank body 111 volume.This interior tank body 111 is provided with a flow-off at the highest liquid level 20 place, spill pipe is connected to this interior tank body 111 by this flow-off and is communicated with space in this interior tank body 111, make when LNG liquid is filled into the highest liquid level 20 of this interior tank body 111, LNG liquid flows into spill pipe.
It is (not shown that this spill pipe comprises spill pipe in tank, Fig. 1 only illustrates the flow direction of spill pipe liquid in this tank) and the outer spill pipe 12 of tank, in this tank, one end of spill pipe is connected to the flow-off place of interior tank body 111 and is communicated with interior tank body 111, and in tank, the other end of spill pipe is connected with outer spill pipe 12 one end of tank by the dual-sided splice being arranged on outer tank body 112 place.
Outer spill pipe 12 the other end of tank is connected to overflow cylinder 13.This overflow cylinder 13 comprises a pipe 131 and for closing this pipe 131 and being positioned at the shrouding 132 on this pipe 131 top.This overflow cylinder 13 can be stainless steel overflow cylinder.
LNG liquid in interior tank body 111 and the cryogenic gas of part LNG liquid gasification flow into overflow cylinder by spill pipe.
Temperature controlling device 14 is arranged on the top of this overflow cylinder 13, and it comprises temperature transducer and warning device, and temperature transducer is electrically connected with warning device.The temperature value of detection for detecting the temperature in overflow cylinder 13, and is converted to electrical signal by temperature transducer.When the temperature that temperature transducer detects is lower than setting value, warning device automatic alarm.
This LNG storage tank 10 also comprises and is arranged on overflow cylinder 13 top and the blow-down pipe 15 be connected with overflow cylinder 13.This blow-down pipe 15 is for being discharged into after the liquid gasification in overflow cylinder 13 in air.
Further, this LNG storage tank also comprises controller and is arranged on tank body and fills solenoid valve on house steward's valve, and solenoid valve, temperature transducer and warning device are electrically connected with controller respectively.This controller can be PLC (programmable controller).
When LNG Liquefied natural gas flows into overflow cylinder 13, temperature sensor senses to the temperature value of this overflow cylinder 13 lower than predetermined temperature value time, this temperature value is converted to electrical signal by temperature transducer, and this electrical signal is fed back to controller, controller by this electrical signal compared with setting value, if be less than setting value, then controller is to warning device one electrical signal, this warning device is reported to the police, and this controller is to the solenoid valve power-off filled on house steward's valve simultaneously, stops filling of LNG Liquefied natural gas.
As mentioned above, this warning device is capable of automatic alarm, reports to the police after also can giving a signal by controller again.
In addition, above-mentioned overflow cylinder, temperature controlling device, blow-down pipe can be placed in a casing, and this casing can directly be placed on hull.
LNG storage tank of the present utility model is as follows for the process realizing monitoring tank level:
In LNG storage tank filling process, if deep cooling LNG liquid do not reach tank body the highest liquid level time, the cryogenic gas of part deep cooling LNG liquid gasification is introduced in overflow cylinder in spill pipe, temperature controlling device carries out electrical signal feedback according to temperature now, PLC compares according to feedback electrical signal and setting value (this setting value sets according to deep cooling LNG fluid temperature), if be now greater than setting value, PLC does not take any action; If deep cooling LNG liquid reach tank body the highest liquid level time, deep cooling LNG liquid flows into overflow cylinder in spill pipe, temperature controlling device is according to this temperature signal fed-back current signals, PLC compares according to fed-back current signals and setting value, now setting value should be less than, PLC sends signal to warning device, simultaneously to the solenoid valve power-off filled on house steward's valve, stops filling of LNG liquid.
Cryogenic gas after cryogenic gas in overflow cylinder and deep cooling LNG liquid gasification is thrown in the air of safety zone by blow-down pipe, thus realizes the automatically-monitored and warning to the full liquid level of LNG storage tank.
To sum up, LNG liquid in tank body is introduced in overflow cylinder by spill pipe by LNG storage tank of the present utility model, and temperature controlling device is set in overflow cylinder, when temperature controlling device detects that temperature in overflow cylinder is lower than setting value, temperature controlling device automatic alarm, thus realize the automatically-monitored and warning to the full liquid level of LNG storage tank.In addition, if when this LNG storage tank being placed on hull, this overflow cylinder also can stop the liquid flowed out from spill pipe to contact with deck in ship structure, protection deck.
In addition, this LNG storage tank is also provided with blow-down pipe on overflow cylinder, to be thrown in the air of safety zone by the cryogenic gas flowed in overflow cylinder and the cryogenic gas after deep cooling LNG liquid gasification by blow-down pipe, ensure the personnel of LNG storage tank periphery and the safety of property.
These are only better possible embodiments of the present utility model, and unrestricted protection domain of the present utility model, all utilization the utility model specifications and the change of the equivalent structure done by accompanying drawing content, be all included in protection domain of the present utility model.
