Description

Technical Field

[0001] The utility model relates to the technical field of water bath type desuperheaters, in particular to a water bath type desuperheater for desuperheating superheated steam. Background Art

[0002] The water bath desuperheater for superheated steam desuperheating is a device used to prepare dry saturated steam. Dry saturated steam refers to the state in which steam and its liquid coexist under thermal equilibrium conditions under a specific pressure, and the steam does not contain liquid water particles. The superheated steam is flowed through isobaric saturated water after flow adjustment. The isobaric saturated water absorbs the superheated part and evaporates. The superheated steam overflows from the water bath, carrying a small amount of saturated water, which is intercepted and separated by a micron-level filter to obtain dry saturated steam.

[0003] At present, the commonly used superheated steam cooling method is pipeline spraying, that is, spraying water into the steam pipeline. The water is atomized and mixed in the pipeline for a certain time and length to obtain slightly superheated steam. The slightly superheated degree of the outlet steam is controlled by the amount of water sprayed. However, it requires a longer straight pipe mixing section, cannot obtain fully saturated steam, and has a limited flow ratio range. Utility Model Content

After the superheated steam is adjusted in flow state, it flows into the interior of the storage tank through the gas transmission pipe and the air inlet pipe, and then heats the hot water inside the storage tank. The isobaric saturated water absorbs the superheated part and evaporates. The superheated steam overflows from the water bath, carrying a small amount of saturated water and flowing upward. It flows through the micron-level filter to intercept and separate, separates water molecules, and then obtains dry saturated steam. The dry saturated steam is discharged to the outside through the exhaust pipe. There is no requirement for a straight pipe section, and the full flow range can be adjusted steplessly to obtain saturated steam, thereby improving the practicality of the water bath desuperheater for superheated steam cooling.
