Description

Split type steam temperature and pressure reducing device Technical Field The utility model relates to the technical field of temperature and pressure reduction, in particular to a split type steam temperature and pressure reduction device. Background In industrial production process, steam temperature and pressure reduction devices are widely applied to a plurality of fields such as energy conversion, chemical industry, food processing and the like, and steam parameters are accurately regulated and controlled so as to meet the requirements of different technological processes. However, the existing steam temperature and pressure reducing device has a plurality of problems. Firstly, the device overall structure is compact, leads to relief pressure valve, governing valve and gas-supply pipe integrated into one piece, very easily appears damaging because of bulky, the structure is complicated in the transportation, and transportation cost is higher. Secondly, in the aspect of steam cooling, the traditional device usually adopts a mode of directly spraying cold water into a pipeline to cool the steam, the mode can lead to local quenching and shock heating phenomena in the pipeline, metal fatigue is extremely easy to be caused due to rapid temperature change, and further a gas pipe is broken, so that the service life of the device is seriously influenced, meanwhile, in the cold water evaporation process, the pipeline is corroded, the pipeline is broken and equipment is damaged, and evaporated substances pollute the steam, so that the normal use of the device is influenced.
