Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
The utility model provides a kind of LNG Liquefied natural gas underground gas storage and air delivery device, as shown in Figure 1, comprises ground installation and underground installation.Wherein underground installation comprise be arranged on underground explosive operation between 14, explosion proof door 15 is provided with in 14 between explosive operation, air feeder 7 is provided with after explosion proof door 15, air feeder 7 is connected with Dewar vessel 4 by drain pipe 5, Dewar vessel 4 is also connected with liquid inlet pipe 3, and liquid inlet pipe 3 is filled with LNG Liquefied natural gas for giving Dewar vessel 4 and flows in air feeder 7 by drain pipe 5; Air feeder 7 is also connected with vaporizer 10 by vaporizer inlet tube 9, and vaporizer 10 is connected to form loop by gasifier exit pipe 11 and air feeder 7 again, and vaporizer inlet tube 9 and vaporizer outer pipe 11 are provided with cryogenic globe valve 6; Air feeder 7 is also connected with diffuse channel 8, and diffuse channel 8 passes on ground, Dewar vessel 4 is provided with Dewar vessel bleeding device 13, and Dewar vessel bleeding device 13 is connected with diffuse channel 8; After gasifier exit pipe 11 connects air feeder 7, air feeder 7 connects user pipe 12, and rock gas is supplied user.
Air feeder 7 is also connected with controller 1 by communication cable 2, controller 1 is for being arranged on the ground installation on ground, controller 1 is responsible for collecting device Operational Limits and coupled touch screen or host computer can be used to carry out operating the object reaching remote control equipment according to parameter current adjustment equipment running status simultaneously, if client needs can increase Ethernet or wireless remote function by desired data teletransmission in handheld device or other computers, when unit exception can automatically be cut off or change and send alarm command to audible-visual annunciator.
A kind of LNG Liquefied natural gas underground gas storage of the utility model and air delivery device also comprise monitoring alarm device, are provided with combustible gas detector 16 and operation room monitoring camera 19 in 14 between explosive operation; Monitoring alarm device also comprises ground installation, comprises the audible-visual annunciator 17, ground monitoring camera 18 and the infrared emission device 20 that are arranged on ground.
The using method of a kind of LNG Liquefied natural gas underground gas storage of the utility model and air delivery device is, LNG Liquefied natural gas tank car fills to Dewar vessel, this device Dewar vessel liquid inlet pipe used is cryogenic hose, being placed at ordinary times between explosive operation, is that extended operation room is connected on the liquid outlet of LNG Liquefied natural gas tank car when needing to Dewar vessel fluid injection; Dewar vessel, for storing LNG Liquefied natural gas and being incubated, can freely be chosen suitable Dewar vessel according to the demand of user's gas-storing capacity thus not lose again the effect of Economy while reaching safety and stability air feed object; LNG Liquefied natural gas is transported to the pipeline of air feeder by the Dewar vessel drain pipe that Dewar vessel connects, and pipeline is furnished with cryogenic globe valve, and pneumatic or electric valve can be used if desired to carry out telecontrol; Air feeder mainly refers to liquefied natural gas gasifying, temperature adjustment, regulator, the multiple choices such as supercharging sled, storage tank supercharging sled, liquefied natural gas gasifying pry regulator and BOG recovery sled of unloading according to different operating mode; Vaporizer is air-heating type gasifier, and the heat exchange area for increasing LNG Liquefied natural gas and air makes LNG Liquefied natural gas fast endothermic vaporize, and carburetor inlet place carries check function, prevents the rock gas after gasifying from blowing back in liquefied natural gas cylinder bottle; Then rock gas is used by user pipe supply user.
And combustible gas detector and the safe condition of operation room monitoring camera at any time between policer operation, ground monitoring camera and infrared emission device are for ensureing the safety of operation room entrance and controller, if it is abnormal that on-the-spot any electric elements detects that equipment occurs, or station district occurs that non-working person swarms into or carries out destroying in violation of rules and regulations, abnormal information can be sent to controller by communication cable, controller, to audible-visual annunciator order, makes its sound warning and light warning.
When the parts in system need calibrating, maintenance or operation time operator open explosion proof door and enter between the explosive operation of underground, worked rear closedown explosion proof door, and not operation necessity must not be opened.If between the explosive operation of the situation such as war, the attack of terrorism of generation underground can the extraneous accident of reduction of high degree on the impact of system, even if it is fried that extraneous accident causes system to occur, build up with high strength cement because of underground buried between the explosive operation of underground, therefore the abrupt release of explosion energy can be stoped and its major part is imported the earth, greatly reduce the collapsing force of accident.
