Abstract
The invention provides an air cooling island pipeline freezing prevention structure for overcoming the defects existing in the prior art. Through the structure, it can be guaranteed that a butterfly valve cannot be frozen to burst, the service life of the butterfly valve is prolonged, and the windproof and sandproof effects can be achieved. For solving the technical problems, according to the technical scheme, the air cooling island pipeline freezing prevention structure comprises an air cooling island body, a main pipe and the butterfly valve; the main pipe is connected to the air cooling island body, the butterfly valve is arranged on the main pipe, the main pipe is provided with a freezing prevention box, the butterfly valve is covered with the freezing prevention box, and the freezing prevention box is used for protecting the butterfly valve to prevent the butterfly valve from being frozen to burst. The air cooling island pipeline freezing prevention structure can be widely applied to the field of air cooling island pipeline freezing prevention.
Description
Technical field
Air-Cooling Island freezing prevention tubing structure of the present invention, belongs to Air-Cooling Island freezing prevention tubing technical field.
Background technology
Existing Air-Cooling Island main pipeline butterfly valve easily freezes when closing in the winter time bursting by freezing, owing to air cooling butterfly valve is expensive, causes operating cost to increase, and additionally main pipeline butterfly valve the most easily receives the erosion of dust storm, causes damaging.
Summary of the invention
Instant invention overcomes the deficiency that prior art exists, it is provided that a kind of Air-Cooling Island freezing prevention tubing structure, not only can ensure that butterfly valve, not by bursting by freezing, extends the service life of butterfly valve, and can also play the effect of checking the wind and fixing the shifting sand.
In order to solve above-mentioned technical problem; the technical solution used in the present invention is: Air-Cooling Island freezing prevention tubing structure; including Air-Cooling Island body, supervisor and butterfly valve; described supervisor is connected on Air-Cooling Island body; described butterfly valve is arranged on supervisor; being provided with frost box on described supervisor, butterfly valve is covered by described frost box, and described frost box is used for protecting butterfly valve in order to avoid bursting by freezing.
Being provided with accompanying-heat cable in described frost box, described accompanying-heat cable is wound around and is arranged on butterfly valve, butterfly valve carries out auxiliary heating, it is ensured that butterfly valve is not by bursting by freezing.
It is provided with temperature sensor on described butterfly valve, described temperature sensor is electrically connected with Power Plant DCS control system by wire, described accompanying-heat cable also electrically connects with Power Plant DCS control system, after the temperature signal analytical calculation that temperature sensor is gathered by described Power Plant DCS control system by temperature sensor, when the temperature of butterfly valve is less than design temperature, controls accompanying-heat cable and butterfly valve is heated.
Described butterfly valve is motor-operated isolation valve.
The present invention compared with prior art has the beneficial effect that the present invention adds frost box at Air-Cooling Island main pipeline butterfly valve; accompanying-heat cable is set in frost box; temperature sensor; it is connected with Power Plant DCS control system; automatically heat when accompanying-heat cable is less than technological temperature, can be to air cooling main pipeline and butterfly valve anti-frost protection.Easily freeze when air cooling butterfly valve is expensive and winter closes bursting by freezing, arranges automatic heating device and can well protect the good operation of air cooling motor-operated isolation valve and whole air cooling system, improves temperature mode and the reliability of whole air cooling system.The most applicable in severe cold area.The effect of checking the wind and fixing the shifting sand can be played simultaneously.
