Abstract
The invention relates to a natural gas collecting and leakage monitoring device, which mainly comprises a water tank. The lower of the water tank is respectively equipped with an inlet and an outlet which are communicated with an enclosed water cooling pipeline of a cooler after a supercharger of a pressure regulating station; baffle plates capable of fully reducing flow velocity of cooling water and effectively collecting gas in the water are arranged in the water tank; a ball-float visor with a valve at the top is arranged at the top of the water tank, and comprises a ball-float cylinder which is vertically arranged at the top of the water tank and communicated with the water tank; a ball float which can flow up and down in the ball-float cylinder is arranged in the ball-float cylinder, and the upper sidewall of the ball-float cylinder is equipped with a visor window used for observation; and an in-situ magnetic flipping liquid-level meter used for observing whether liquid level drops is arranged on the middle sidewall of the water tank.
Description
Technical field
What the present invention relates to is that the rock gas that arranges in the natural gas boosting machine cooling water system of a kind of fuel-burning power plant is collected and leakage monitor, belongs to the fuel-burning power plant design field.
Background technology
At present in the conventional design of natural gas pressure regulating station, fuel-burning power plant, the supercharger aftercooler adopts the enclosed chilled water to cool off, directly return after enclosed chilled water and the natural gas line heat exchange in the full factory enclosed water water circulation system, this design can reduce natural gas temperature after the supercharging, makes the air inlet requirement of its satisfied combustion machine unit.But because the rock gas wall pressure of aftercooler is higher than enclosed water wall pressure, if heat-exchange tube of cooler leaks, then rock gas will enter whole closed Water System, and the hazardous location will enlarge, directly dangerous safety to main building equipment.Therefore must adopt an effective measure, stop this potential safety hazard, guarantee unit safety stable operation.
Summary of the invention
The object of the invention is to overcome in the prior art deficiency of can't the fast monitored natural gas leaking and reporting to the police rapidly; provide a kind of simple in structure; easy to use; cost is low; can effectively avoid the expansion of hazardous location; and find that in time heat exchanger tube leaks, and in time shut down maintenance, guarantee that the rock gas of safety in production is collected and leakage monitor.
The objective of the invention is to finish by following technical solution: described rock gas is collected and leakage monitor, it mainly comprises a water tank, its underpart is provided with respectively enclosed water out and the import that is communicated with voltage regulating station supercharger aftercooler enclosed cooling water pipeline entrance and exit, is provided with the aft cover plate that can fully reduce the chilled water flow velocity and effectively collect gas in the water in the water tank; The top of water tank is provided with a floating-ball viewing mirror device with the top valve.
Described floating-ball viewing mirror device comprises a ball float cylinder that is vertically set on tank top and is communicated with water tank, and this ball float cylinder is built-in with a ball float that can fluctuate in the ball float cylinder, is provided with on the upper portion side wall of ball float cylinder for the visor window of observing.
Be provided with the earth magnetism flap level gauge that whether descends being used for the observation liquid level on the sidewall of described water tank middle part.
The present invention mainly is by the flow velocity of reduction closed-type circulating cooling water, effectively collects gas in the water, and then detection alarm, and it has following technique effect:
One, can effectively collect and monitor the leakage of rock gas, report to the police at central station of floating dock at once in case monitor rock gas;
Two, can use hand-held gas probing instrument to confirm that the gas that leaks is rock gas, and then shutdown inspection and reparation problem;
Three, improve the security of closed Water System, avoided the danger that causes because of the natural gas leaking diffusion.
Description of drawings
Fig. 1 is the local schematic diagram of arranging of voltage regulating station of the present invention supercharger cooling water outlet and inlet pipeline.
Fig. 2 is the structural representation of rock gas collection of the present invention and leakage monitor.
Embodiment
The present invention will be described in detail below in conjunction with drawings and Examples: shown in Figure 1, rock gas of the present invention is collected and leakage monitor is installed on the entrance 2 of voltage regulating station supercharger 1 aftercooler enclosed cooling water pipeline and export 3 places, and the pipeline between the present invention and refrigeratory arranges safety valve as one of means of confirming natural gas leaking.
Shown in Figure 2, the present invention mainly comprises a water tank 4, the bottom of this water tank 4 is respectively arranged with enclosed water inlet 5 and the outlet 6 that is communicated with voltage regulating station supercharger aftercooler enclosed cooling water pipeline, is provided with the aft cover plate 7 that can fully reduce the chilled water flow velocity and effectively collect gas in the water in the water tank 4; The top of water tank 4 is provided with a floating-ball viewing mirror device with top valve 8.
Shown in Fig. 2, described floating-ball viewing mirror device comprises a ball float cylinder 9 that is vertically set on tank top and is communicated with water tank 4, this ball float cylinder 9 is built-in with a ball float 10 that can fluctuate in the ball float cylinder, be provided with on the upper portion side wall of ball float cylinder 9 for the visor window 11 of observing.
Be provided with the earth magnetism flap level gauge 12 that whether descends being used for the observation liquid level on described water tank 4 middle parts or the middle and upper part sidewall.
Embodiment:
The closed-type circulating cooling water entrance enters a large vessel space---water tank 4, and at the water tank 4 interior aft cover plates 7 that arrange, has fully reduced the chilled water flow velocity, can effectively collect gas in the water, comprises collecting rock gas to the headroom of water tank 4;
The top design of water tank 4 has the floating-ball viewing mirror device, during normal operation, because of enclosed water with pressure, and ball float 10 is at the highest notch, when gas is assembled at ball float cylinder 9 tops of floating-ball viewing mirror device, ball float 10 will be descended, this moment little valve that opens the mirror device top, whether be rock gas, if detected by the hand-held detection instrument if gathering air with hand-held gas probing instrument detection, then need the hard stop inspection, until problem is repaired:;
Be designed with regard to earth magnetism flap level gauge 12 between floating-ball viewing mirror device and the water tank middle part, if finding to record liquid level descends, also need adopt with the hand-held detection instrument and survey, to determine the liquid level decrease reason, if really gather due to the rock gas owing to the top, then hard stop inspection is until repair problem;
In case monitor natural gas leaking, then report to the police at central station of floating dock immediately, and in time check and eliminate the natural gas leaking point.
