Abstract

The invention discloses a deoxygenation head. The deoxygenation head comprises a barrel body, an exhaust outlet formed in the top end of the barrel body and a water outlet formed in the bottom end of the barrel body, the water outlet is provided with a connection flange, the barrel body is internally provided with a rotary membrane deoxygenation layer, a first steam layer, a filtration layer and a second steam layer in sequence from top to bottom, the rotary membrane deoxygenation layer comprises a rotary membrane set water chamber, multiple rotary membrane pipes which are vertically arranged in the rotary membrane set water chamber at intervals and a lyophobic water inlet, a demineralized water inlet and a condensed water inlet which are formed in the barrel wall and communicated with the rotary membrane set water chamber, and water permeation holes are formed in the rotary membrane pipes. The deoxygenation head is simple in structure, deoxygenation is conducted twice through the rotary membrane deoxygenation layer and the filtration layer, deoxygenation efficiency is greatly improved, and the deoxygenation head is adapted to industrialized application.

Description

technical field [0001] The invention relates to a deaeration device for boiler feed water, in particular to a deaeration head for physical treatment. Background technique [0002] The deoxygenation head of the prior art adopts the thermal deoxygenation method, and there are many equipments, and the maintenance is troublesome. When the equipment is running, it needs to carry out multi-stage slurry reaction, and the running time is long. [0003] Chinese patent authorization announcement number 202188490U discloses a boiler self-deaeration structure device, including a feed water deaeration device and a steam drum, an integrated deaeration head is set on the steam drum, the steam drum doubles as a deaeration water tank, and the steam drum is connected to the deaeration head The deaeration head is equipped with a water chamber of a film generator group, a water spray tray, a liquid vapor net filler and an exhaust device. However, its structure is complicated and its production...
