In figure, 1. controller, 2. communication cable, 3. admission line, 4. high-pressure gas pipeline, 5. pressure regulating metering device, 6. diffuse channel, 7. user pipe, 8. explosion proof door, 9. between explosive operation, 10. combustible gas detector, 11. operation room monitoring cameras, 12. audible-visual annunciators, 13. ground monitoring cameras, 14. infrared emission devices.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
The invention provides a kind of compressed natural gas underground gas storage and air feeder, as shown in Figure 1, comprise ground installation and underground installation, underground installation comprise be arranged on underground explosive operation between 9, explosion proof door 8 is provided with in 9 between explosive operation, arrange pressure regulating metering device 5 in explosion proof door 8, pressure regulating metering device 5 connects diffuse channel 6, and diffuse channel 6 is connected to ground and diffuses; Pressure regulating metering device 5 is also connected with user pipe 7, and user pipe 7 is directly gas user air feed; Pressure regulating metering device 5 is also connected with high-pressure gas pipeline 4, and the caliber of high-pressure gas pipeline 4 is between DN300-DN1000, and its pipeline adopts chrome molybdenum, and high-pressure gas pipeline 4 is arranged on underground; High-pressure gas pipeline 4 connects admission line 3, and admission line 3 is filled with compressed natural gas in high-pressure gas pipeline 4; Wherein also be provided with watch-dog in 9 between explosive operation, watch-dog is to be arranged between explosive operation combustible gas detector 10 in 9 and operation room monitoring camera 11.
Wherein ground installation comprises controller 1, and controller 1 is connected with pressure regulating metering device 5 by communication cable 2, and pressure regulating metering device 5 includes automatic cut off device, automatic pressure regulating device, intelligent device for adding odor, flow harvester and control gear; This data information by gathering pressure data in natural-gas transfer pipeline, adding smelly data and data on flows, and is sent to controller 1 by pressure regulating metering device 5, and controller 1 sends and cuts off instruction to automatic cut off device, adds smelly instruction to intelligent device for adding odor; Ground installation also comprises monitoring alarm device, and what monitoring alarm device was concrete is ground monitoring camera 13, audible-visual annunciator 12 and infrared emission device 14.
The using method of a kind of compressed natural gas underground gas storage of the present invention and air feeder is, compressed natural gas is discharged in high-pressure gas pipeline 4 through admission line 3 by compressed natural gas tank car, compressed natural gas is adjusted to by pressure regulating metering device 5 pressure that user needs during use, then through temperature adjustment, measure, add the process such as smelly after supply user by user pipe 7 and use.If can diffuse by the manual diffusion valve on manual unlocking diffuse channel 6 when in working procedure, superpressure phenomenon appears in system arbitrary portion, if manually do not diffuse, safety valve automatically can have been opened and disperse, time under the pressure that pressure diffuses to setting, safety valve cuts out automatically.
Whether combustible gas detector 10 is monitored at any time exists leakage, all situations in operation room monitoring camera 11 policer operation in real time, the entrance of 9 and the safe condition of station district periphery between ground monitoring camera 13 and infrared emission device 14 moment monitoring underground explosive operation, when the arbitrary element in pressure regulating metering device 5 notes abnormalities, by communication cable 2, abnormal signal is sent to controller 1, alarm command is provided to audible-visual annunciator 12 after controller 1 analytic signal, audible-visual annunciator 12 is sounded and light warning, notifies that staff processes exception in time.
When needs operation or maintenance, can leave after operation room flame proof door 8 being closed completely after between operator's opening operation, flame proof door 8 completes work at present, if the fortuitous event such as war, the attack of terrorism occurs, 9 can the interference of isolated extraneous accident of high degree between the explosive operation of underground, blast even if system is affected, between the underground explosive operation of high strength, explosion energy can be imported underground with operation room flame proof door 8 by 9, stops blast to cause surrounding and destroys on a large scale.
