Description
Technical field
The utility model relates to the rock gas arranged in the natural gas boosting machine cooling water system of a kind of fuel-burning power plant and collect and leakage monitor, belong 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 carry out cooling, after enclosed chilled water and natural gas line heat exchange, directly return in full factory enclosed water water circulation system, this design can reduce natural gas temperature after supercharging, makes the air inlet requirement of its satisfied combustion machine unit.But due to the rock gas wall pressure of aftercooler, higher than enclosed water wall pressure, if heat-exchange tube of cooler leaks, rock gas will enter whole closed Water System, and hazardous location will enlarge, the direct 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 purpose of this utility model is to overcome in prior art the 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 shut down in time maintenance, guarantee that the rock gas of safety in production is collected and leakage monitor.
The purpose of this utility model completes 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 water in water tank; The top of water tank is provided with a device of the floating-ball viewing mirror 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, on the upper portion side wall of ball float cylinder, is provided with for the visor window of observing.
On the sidewall of described water tank middle part, be provided with once the earth magnetism flap level gauge for observing liquid level whether descend.
The utility model is mainly by reducing the flow velocity of closed-type circulating cooling water, effectively collecting gas in 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 once monitor rock gas;
Two, can use the gas that hand-held gas probing instrument confirm to leak is rock gas, and then shutdown inspection repair problem;
Three, improve the security of closed Water System, avoided the danger caused because of the natural gas leaking diffusion.
The accompanying drawing explanation
Fig. 1 is the local schematic diagram of arranging of voltage regulating station of the present utility model supercharger cooling water outlet and inlet pipeline.
Fig. 2 is the structural representation of the collection of the utility model rock gas and leakage monitor.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in detail: shown in Fig. 1, rock gas described in the utility model is collected and leakage monitor is installed on the entrance 2 of voltage regulating station supercharger 1 aftercooler enclosed cooling water pipeline and exports 3 places, safety valve is set on the pipeline between the utility model and refrigeratory as one of means of confirming natural gas leaking.
Shown in Fig. 2, the utility model 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 water in water tank 4; The top of water tank 4 is provided with a device of the floating-ball viewing mirror 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, on the upper portion side wall of ball float cylinder 9, is provided with for the visor window 11 of observing.
On described water tank 4 middle parts or middle and upper part sidewall, be provided with once the earth magnetism flap level gauge 12 for observing liquid level whether descend.
Embodiment:
The closed-type circulating cooling water entrance enters a large vessel space---water tank 4, and, at the interior aft cover plate 7 that arranges of water tank 4, has fully reduced the chilled water flow velocity, can effectively collect gas in water, comprises and collects the headroom of rock gas to 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, to make ball float 10 descend, micro-valve that opens the mirror device top now, survey with hand-held gas probing instrument whether gather air be rock gas, if detected by the hand-held detection instrument, need the hard stop inspection, until problem is repaired:;
Between floating-ball viewing mirror device and water tank middle part, be designed with regard to earth magnetism flap level gauge 12, recording liquid level if find descends, also need to adopt and surveyed with the hand-held detection instrument, to determine the liquid level decrease reason, if really because top is gathered due to rock gas, hard stop inspection, until repair problem;
Once monitor natural gas leaking, report to the police at central station of floating dock immediately, and check in time and eliminate the natural gas leaking point.
