The invention discloses an efficient
plant dead steam recycling device. The efficient
plant dead steam recycling device comprises a
condensed water inlet, a
condensed water tank, a
condensed water pump, a desalted water inlet, a mixed water tank, a deoxidizer, a deoxidized water outlet, a gas outlet, a
heating furnace water
injection pump and a deoxidized water pump. The efficient
plant dead steam recycling device is characterized in that dead steam on the top of the condensed water tank is introduced into the mixed water tank to be mixed with 45-DEG C cold desalted water for heat exchange, most dead steam is recycled through condensation, the remaining part is introduced into the deoxidizer to serve as
deoxidization steam, the desalted water heated to about 85 DEG C is delivered to the deoxidizer, deaeration and
deoxidization are conducted in the deoxidizer, separated non-condensable gas such as
oxygen is exhausted from the gas outlet, and deoxidized water obtained after
deoxidization is discharged from the deoxidized water outlet to be provided for steam manifold steam production and
heating furnace pipe water injection. Compared with the prior art, the efficient plant dead steam recycling device has the advantages that the technology is simple, the process continuity is good, energy saving and consumption reducing are achieved, safety and
environmental protection are achieved, complete closed recycling of the dead steam can be achieved, a
steaming phenomenon is completely eradicated on the site, heat waste and heat
pollution are eliminated,
energy resources are saved, and clean production is achieved.
