Description
Technical field
The utility model belongs to cooling unit technical field, is specifically related to a kind of Rapid cooling device for turbine.
Background technique
Current steam turbine generally adopts the high-quality such as calcium silicate, alumina silicate thermal insulating material, its thermal insulation property, and Safety performance is obtained for very large improvement, but but considerably increases the wait cool time of overhaul of steam turbine, and single-machine capacity is larger, and its contradiction is more outstanding.Generally adopt the cylinder of method to steam turbine of forced ventilation cooling to cool at present, the main object of steam turbine accelerating cooling is the height of steam turbine, intermediate cylinder.By Theoretical Proof and facts have proved following current cooling more reasonable, thermal shock is produced in air introducing place in order to prevent the cooling incipient stage, control heater heating-up temperature before air is introduced, in advance cooling-air be heated to uniform temperature and change the temperature of cooling-air with the change of cylinder temperature, also needing to control air mass flow simultaneously.But the heated drying air that current cooling equipment cannot provide the suitable cylinder for steam turbine to cool.Need first to carry out warming-up before steam turbine start, and the time cycle of warming-up is long, has a strong impact on the starting time of steam turbine.Steam turbine is when shutting down for subsequent use, and the working life that malaria easily corrodes steam turbine internal unit affects steam turbine even causes potential safety hazard.
Model utility content
The purpose of this utility model is to provide a kind of Rapid cooling device for turbine, has solved the deficiency existed in such scheme.
In order to achieve the above object, technical solution adopted in the utility model is:
A kind of Rapid cooling device for turbine, primarily of suction port flange, oil and water filters, air heater, pipeline, stop valve, pressure gauge, flowmeter, temperature measuring element and gas collecting box composition, suction port flange is provided with on the left of described oil and water filters, connecting tube on the right side of oil and water filters, on the right side of oil and water filters, pipeline is provided with pressure gauge, flowmeter is provided with on the right side of pressure gauge, oil and water filters right lower side is provided with air heater, air heater both sides connecting tube, on the right side of air heater, pipeline is provided with stop valve, below air heater, pipeline connects gas collecting box, temperature measuring element is provided with on the right side of gas collecting box.
Described pipeline is provided with four stop valves.
Pipeline on the right side of described stop valve is provided with air heater.
The utility model can when unit cold start-up, and before start, pre-Hot gas turbine, shortens and even cancel the low speed warming time; During hot starting, first intermediate pressure cylinder be can cool, cylinder temperature and reheat steam temperature matched in advance made; When shutting down for subsequent use, can be used to dry steam turbine, prevent humidity corrosion.Therefore, after using this device, the operational percentage of unit can be improved, alleviate imbalance between power supply and demand, there is obvious realistic meaning and economic benefit.
