Description

Technical Field

[0001] The invention relates to the technical field of temperature reduction and pressure reduction equipment, and in particular to a split temperature reduction and pressure reduction device. Background Art

[0002] The temperature and pressure reducing device, as the name implies, reduces high-temperature and high-pressure steam to low-pressure and low-temperature steam that customers can use. It plays a key role in industry and thermal energy engineering. The split temperature and pressure reducing device is an efficient and reliable steam treatment equipment, which is widely used in various occasions where high-temperature and high-pressure steam needs to be reduced to low-pressure and low-temperature steam. The split temperature and pressure reducing device achieves steam cooling and pressure reduction through two independent processes. First, the steam is decompressed in the pressure reducing valve, and then the decompressed steam is cooled by spraying water. Because a large amount of steam is easily generated inside the pipeline during operation, If the steam directly enters the equipment, it may cause damage to the equipment and even cause a safety accident. Therefore, a temperature and pressure reducer device is needed to reduce the temperature and pressure of the steam to protect the equipment from overheating and overpressure, thereby ensuring the safe operation of the equipment. At present, when cooling and reducing the pressure of the pipeline, the water inlet and nozzle in the temperature and pressure reducing device are used to spray water to cool the steam. Since the steam is transported to the steam cooling device through the pressure reducing valve, the steam contacts the cross-section inside the pipeline during transportation and the steam crowds each other, resulting in the cooling water failing to fully mix with the steam during the falling process, affecting the cooling effect of the steam.
