Deep atomization deoxygenation double-tube film spinner and deaerator with the same

Abstract

The invention discloses a deep atomization deoxygenation double-tube type membrane spinner and a deaerator with the membrane spinner, including a tower head, the inner top of the tower head is fixed and connected around the shell of the spinner, and the shell of the spinner is fixed inside Connect the outer tube of the spinner, one end of the outer tube of the spinner is fixedly connected to one side of the first connecting sleeve, one side of the first connecting sleeve is fixedly connected to the inner tube of the spinner, the outer tube of the spinner is sleeved on the inner tube of the spinner, The outer wall of the inner tube of the membrane is fixedly connected to the outer wall of one end of the outflow sleeve, the other end of the inner tube of the spin membrane and the outer tube of the spin membrane are fixedly connected to one side of the second connecting sleeve, and the inner wall of the inner tube of the spin membrane is fixedly connected to the outer ring of the barrier ring close to the second connecting sleeve. The deep atomization deoxygenation double-tube type membrane spinner and the deaerator with the membrane spinner, through the set spin membrane inner tube and spin membrane outer tube, can enter the spin membrane inner tube through the condensate water port when the condensed water enters the spin membrane inner tube. The outflow sleeve distributed on the outer wall of the inner tube of the spinner is jetted out, and is distributed between the inner tube of the spinner and the outer tube of the spinner, forming water mist.

Description

technical field

[0001] The invention relates to the technical field of deaerators, in particular to a deep atomization deoxygenation double-cylinder type film spinner and a deaerator with the same. Background technique

[0002] Condensed water and make-up water first enter the water chamber of the inner spiral membrane device of the deaerator head, and spray obliquely from the small hole of the membrane tube to the inner hole under a certain water head pressure to form a jet flow, because the inner hole is filled with rising heating steam , the water absorbs a large amount of heating steam during the jet movement (the test proves that the jet movement has an entrainment effect); in a very short time and a small stroke, a violent mixing and heating effect is generated, the water temperature is greatly increased, and the rotating The water continues to spin down along the inner hole wall of the membrane tube to form a tumbling water film skirt (the critical Reynolds number of ...
