The invention discloses a high-pressure industrial steam pressure reducing and cooling device for a thermal power generating unit, and relates to the technical field of electric power industry. The high-pressure industrial steam pressure reducing and cooling device comprises a box body in which a flowing heat absorption medium is stored, a guide-in pipe pipe, a discharge pipe and a flow guiding and cooling mechanism; and the high-pressure industrial steam pressure reducing and cooling device further comprises a pressure reducing and air diffusing assembly and a pressure flow mechanism. The flow guiding and cooling mechanism is arranged in the box body and is used for guiding the steam flow guided in by the guide-in pipe to the pressure reducing and air diffusing assembly and adsorbing the heat of the steam flow in a flow medium heat absorption mode in the flow guide process; and the pressure reducing and flow diffusing assembly is arranged at a flow-guiding port of the flow guiding and cooling mechanism. The whole steam flow is cooled and decompressed by taking impact force generated in the steam flow decompressing process as power to realize circular flowing of the flowing heat-absorbing medium to absorb heat and reduce temperature, power parts such as a motor do not need to be adopted for driving, and energy is saved while the steam flow is effectively cooled and decompressed.
Description
technical field [0001] The invention relates to the technical field of electric power industry, in particular to a decompression and cooling device for high-pressure industrial steam of a thermal power unit. Background technique [0002] In the high-pressure industrial production of thermal power units, a large amount of steam is generated. The current common treatment method for industrial steam is to directly discharge it to the atmosphere. Most of the industrial steam is a high-temperature and high-pressure steam flow, in which the steam flow is discharged through a conduit, and the high temperature will affect the discharge. The surrounding trees and flowers grow, and the impact force generated by the high-pressure jet will destroy the surrounding buildings, so it is necessary to reduce the temperature and pressure of the high-temperature and high-pressure steam. [0003] The existing steam cooling and decompression treatment is to reduce the temperature and pressure by ...
