Abstract

A recovery system of dead steam is prepared as setting steam intake pipe and steam exhaust pipe on the first closed recovery tank, setting pressurization conveying unit for pressurizing inlet steam on steam intake pipe of the first closed recovery tank, connecting steam intake pipe of pressurization conveying unit to dead steam pipe, setting steam sucking unit and the second recovery tank separately before or behind the first closed recovery tank in order to carry out multistage pressurization.

Description

technical field [0001] The invention relates to a exhaust steam recovery system, which can be used for recovery and utilization of exhaust steam of various steam equipment, especially exhaust steam recovery and utilization of steam turbines. Background technique [0002] The exhaust steam of the existing steam turbine is processed through the cooling tower. The steam (exhaust steam) pipe at the end of the steam turbine is directly connected to the condenser. The condenser is a steam-water heat exchanger. Natural cooling water enters the condenser to absorb heat and is The air that is sent to the cooling tower and rises by convection heat transfers heat with the falling cooling water. The exhaust steam in the condenser shrinks sharply from a volume ratio of about 1700:1, forming a vacuum at the end of the steam turbine, thereby increasing the pressure difference between the front and back of the steam turbine and increasing the power generation. The disadvantage of this tech...
