Towerless deaerator

Abstract

The invention discloses a towerless deaerator which comprises a deoxidizing water tank, wherein a water inlet connecting pipe and an exhausting connecting pipe are arranged at the top of the deoxidizing water tank; the upper space of the deoxidizing water tank is a steam space; the lower space of the deoxidizing water tank is a water storage space; a first-level deoxidizing device is mounted at the water inlet connecting pipe in the deoxidizing water tank; a second-level deoxidizing device is mounted in the steam space; the first-level deoxidizing device comprises a water supply atomizer and an eliminator matched with the water supply atomizer; the second-level deoxidizing device comprises a main steam heating device arranged at the upper part of the steam space; and the main steam heatingdevice is connected with a steam port in the top of the deoxidizing water tank through a flange. Through arranging the first-level deoxidizing device and the second-level deoxidizing device, the towerless deaerator fully releases oxygen and noncondensed gas in water to improve the deoxidizing effect; through arranging the main steam heating device provided with a saturated water drainage channel,steam-gas separation is carried out before steam enters the water storage space, so that the steam proportion is increased, the proportion of saturated water except saline water in the deoxidizing water tank is reduced and the deoxidizing quality is improved.

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 connected to the water inlet of the deaeration water tank; the chamber of the deaeration water tank is provided with steam bubbling The steam bubbler includes at least one main pipe, the top of each main...

Problems solved by technology

However, the steam bubbler in this bubbling deaerator is generally installed at the bottom of the deaeration water tank to ensure the heating of the steam below the liquid level in the water tank. Water, and the position of the steam bubbler is relatively low, saturated water is easy to flow into the deoxygenated water tank, pollute the deoxygenated water in the deoxygenated water tank, and also reduce the temperature of the steam, thereby reducing the pressure in the deoxygenated water tank, affecting the deoxygenated water tank. oxygen effect
