Towerless deaerator

Abstract

The invention discloses a towerless deaerator. The towerless deaerator comprises a deoxidization water tank; a water inlet, a vapor inlet and an oxygen exhaustion port are formed in the top of the deoxidization water tank; a water inlet pipe is mounted at the water inlet; a water inlet nozzle is mounted in the water inlet pipe in the deoxidization water tank; a vapor distribution mechanism is mounted in the deoxidization water tank; a height adjustment mechanism of the vapor distribution mechanism is arranged at the top of the deoxidization water tank; the vapor distribution mechanism comprises a vapor inlet pipe connected with the vapor inlet in a sealing manner; a vapor distribution pipe is fixed at the bottom end of the vapor inlet pipe; vapor branch pipes are mounted on the steam distribution pipe; and a rotation spray head is mounted at the outer end of each vapor branch pipe. According to the towerless deaerator, the height adjustment mechanism can be used for adjusting the height of the whole vapor distribution mechanism according to water level condition in the deoxidization water tank, so that vapor can be reasonably distributed to everywhere in the deoxidization water tank; the rotation spray head can be used for driving the water in the deoxidization water tank to move circularly while spraying out vapor, so that the deoxidization effect of the water at everywhere isimproved, the generation of incrustation can be avoided and the deoxidization effect is high.

Description

technical field [0001] The invention relates to a feed water deaeration technology, in particular to a deaerator without a tower. Background technique [0002] As a main equipment for removing dissolved oxygen and other gases in the feed water of the thermal system, the thermal deaerator can effectively prevent thermal equipment from corroding and ensure the safe operation of the thermal system. The main deaerators in the prior art are bubbling deaerators and rotary film deaerators. These deaerators are mainly composed of a deaeration tower head, a deaeration water tank, connecting pipes and external parts. [0003] The prior art discloses a bubbling deaerator, which includes a deaeration water tank, and a water inlet nozzle is installed at the bottom end of the water inlet pipe connected to the water inlet of the deaeration water tank; a steam bubbler is arranged in the chamber of the deaeration water tank The steam bubbler includes at least one main pipe, the top of each ...

AI Technical Summary

Problems solved by technology

However, the height of the steam bubbler in this bubbling deaerator cannot be adjusted according to the needs, especially when the water level is low, because the position is fixed, the steam cannot be sprayed into the water from under the water surface, and the range that the steam can reach Limited, sometimes, there will be local overheating, and it is impossible to achieve uniform heating in the entire water tank
