Abstract

The invention discloses a steam-to-air discharging white fog eliminating device. The device comprises a steam-air heat exchanger (10) and a compressed air injector (20), wherein the compressed air injector (20) comprises an outer shell (21), an inner nozzle (22) and an inner cavity (23), a steam inlet and a mixed gas outlet are formed in the outer shell (21), the outlet end of the inner nozzle (22) faces the mixed gas outlet of the outer shell (21), the steam-air heat exchanger (10) comprises a steam inlet, a steam outlet, a compressed air inlet and a compressed air outlet, the steam outlet ofthe steam-air heat exchanger (10) communicates with the steam inlet on the outer shell (21), and the compressed air outlet of the steam-air heat exchanger (10) communicates with the inlet end of theinner nozzle (22). According to the steam-to-air discharging white fog eliminating device, a temperature and saturation of to-air discharging steam can be reduced, so that a large amount of white foggenerated by steam cooling during steam outward discharging can be eliminated.

Description

technical field [0001] The invention relates to a whitening device for discharging water vapor to the air. Background technique [0002] As my country's environmental protection requirements become increasingly stringent, the management of "running, leaking, dripping, and leaking" in various production plants is imminent, such as the large amount of heat saturation generated by steam venting pipeline outlets in mass production equipment and boiler periodic sewage tanks. The steam is directly discharged to the atmosphere on the spot, and the vented steam will be mixed with relatively low-temperature cold air in the atmosphere at the discharge outlet to cool down, and "small droplets" will be precipitated and form white mist, commonly known as "white steam". This results in evaporative loss of water resources. At the same time, the hot "small droplets" discharged at high altitude in summer will cause burns to the inspection personnel, and the cold "small droplets" in winter wil...
