The utility model discloses the constitution includes: a cooling water inlet pipeline (1), a water return pipeline (13), a cooling water inlet header (4) and a cooling water return header (12); the cooling water inlet pipeline penetrates into the protective box (19) to be communicated with the cooling water inlet collecting pipe, and the cooling water inlet collecting pipe is communicated with the cooling water return collecting pipe through a plurality of cooling pipes (5) surrounding the high-pressure cutoff module; the water return pipe penetrates into the protective box and is communicated with the cooling water return header. The utility model is used for high pressure emergency trip module cooling and protection.
Description
Technical Field
The utility model relates to a high pressure interdiction module cooling and protection field specifically are a low-cost, safe high pressure interdiction module protection and cooling device.
Background
The high-pressure interruption module is a key component of a turbine regulating security system, controls an oil discharge port of safety oil of an EH oil system of a turbine and is a general hub of the whole interruption system. When the unit needs emergency shutdown, the shutdown signal sent by DEH or ETS makes four high-voltage interruption solenoid valves on the high-voltage interruption module lose power, and simultaneously, the quick-closing solenoid valves of each throttle and the main throttle are electrified, so that the safe oil pressure is quickly discharged, each throttle is quickly closed, and the steam inlet passage of the steam turbine is interrupted. The high-pressure cutoff modules of the #1 and the #2 engines of the factory are placed near a main high-pressure valve of a steam engine room with the pressure of 6 meters, the temperature of an electromagnetic valve is high in the daily operation process, the long-term high-temperature operation environment is not good for the relevant sealing parts of the high-pressure cutoff modules, the relevant sealing parts are easy to age and further lose efficacy, high-pressure oil is filled in the cutoff modules, once the sealing parts lose efficacy, high-pressure cutoff safety oil is drained, all oil inlet isolation valves are disconnected, high-pressure oil in all oil engine chambers is drained at the same time, and the engine sets are shut off, so that the engine sets are not stopped. Meanwhile, the EH oil is leaked on the spot and is not easy to clean because the EH oil is toxic. And the periphery is provided with a plurality of high-temperature high-pressure steam pipelines, and if leakage occurs, the high-pressure cutoff module device is easy to be damaged. Meanwhile, the interruption module device is not protected at all, so that the electromagnetic valve is easy to operate due to mistaken touch of people, and the unit is not stopped (such as cleaning equipment for cleaning environmental sanitation personnel is touched by mistake). The high temperature of the solenoid valve can cause the temperature rise of a cable insulating part electrified by the solenoid valve, and the heat can be generated by the current flowing through the coil of the solenoid valve. A large amount of heat cannot be taken away, which may cause overheating of the coil and the insulating member. If the insulating part is damaged due to overheating, the coil discharges, and control over the electromagnetic valve is lost. Overheating damage to the coil can also lead to failure of the solenoid control. According to the knowledge of the inquiring manufacturer, if the temperature of the electromagnetic valve is high for a long time, the service life of the electromagnetic valve is shortened. And advise not to run longer than 80 ℃. And four electromagnetic valves in the high-voltage blocking module are provided with temperature monitoring devices, and the temperature is uploaded to the front of the DCS disk.
At the present stage, a measure for ensuring that the high-pressure cutoff module does not operate at high temperature and protects is to draw an isolation fence, and when the environmental temperature is continuously higher than 25 ℃ and any one of the temperatures of the electromagnetic valves exceeds 75 ℃, a temporary fan is additionally arranged near the high-pressure cutoff module to operate continuously to assist in cooling. Because the temporary fence can not completely isolate and protect, and the reliability of temporary fan equipment is not high, a low-cost and safe high-voltage interruption module protecting and cooling device is designed for the reason.
Disclosure of Invention
The utility model aims at providing a stable high pressure interdiction module cooling and protector in order to compensate the not enough of prior art, this equipment covers the module with the dustcoat, still keeps apart outside heat source when accomplishing the protection, takes away the heat that the module operation produced with water-cooling circulation flow.
The above purpose is realized by the following technical scheme:
a cooling and protection device for a high-pressure emergency break module comprises a cooling water inlet pipeline, a water return pipeline, a cooling water inlet header and a cooling water return header;
the cooling water inlet pipe penetrates into the protective box and is communicated with the cooling water inlet collecting pipe, and the cooling water inlet collecting pipe is communicated with the cooling water return collecting pipe through a plurality of cooling pipes which surround the high-pressure cutoff module;
the water return pipe penetrates into the protective box and is communicated with the cooling water return header.
The cooling and protection device for the high-pressure emergency interruption module is characterized in that a cover plate above the protection box is connected with the side surface through a buckle.
The cooling and protection device for the high-pressure emergency trip module is characterized in that an inlet manual door is installed on a cooling water inlet pipeline.
The cooling and protection device for the high-pressure emergency trip module is characterized in that a return water pipeline is provided with a return water manual door.
Has the beneficial effects that:
1. the utility model discloses can realize the protection to high pressure interdiction module to and isolated external heat source, prevent that steam conduit from touching the harm of high pressure interdiction module and the risk of people for the mistake on every side.
2. The utility model discloses set up many cooling tubes that encircle on high pressure interdiction module, the cooling tube is the copper pipe, the heat that produces when closed hydrologic cycle flows and takes away high pressure interdiction module operation can play best cooling effect, current add interim fan under high temperature environment on every side, the easy insulation damage of power connection of interim fan leads to the fan bad operation, the fan is long-time to be moved simultaneously, equipment reliability is not enough, lay cable and fan long-time operation moreover, consume higher.
