Problems solved by technology

[0005] The solution provided by the prior art can better remove the oxygen in the water body, but since the non-condensable gas is directly discharged from the exhaust pipe to the atmosphere during the oxygen removal process, the exhaust noise is large during the process of removing the non-condensable gas. At the same time, part of the steam is also discharged together, resulting in a waste of part of the energy

The upper part of the housing, the first deaeration housing and the second deaeration housing are hollow and communicated with each other, the upper part of the second deaeration housing is provided with a water chamber, and the second deaeration housing on both sides of the water chamber is connected to the water inlet , a vertical nozzle pipe is arranged in the water chamber, the upper and lower ports of the nozzle pipe are arranged outside the water chamber, the water inlet hole is spirally arranged on the surface of the nozzle pipe, the upper end of the second deaeration shell on the upper part of the water chamber is connected to the exhaust assembly, and the water chamber A water distribution component is installed in the second deaeration shell at the lower part, a packing layer is set under the water distribution component, and a third steam input pipe is set between the water distribution component and the packing layer; Effectively recycle water and reduce steam discharge, solve the problem of exhaust with water to reduce water resource loss, stable operation, no vibration and noise.

Description

technical field [0001] The invention belongs to the technical field of boiler feed water deaeration, and in particular relates to a thermal spin film deaerator. Background technique [0002] With the development of high-parameter and large-capacity generator sets, the system is becoming more and more complex, and the increase in the capacity of a single unit makes the requirements for the economy, safety and reliability of the entire unit operation higher, and the requirements for water supply quality are becoming more and more stringent. The presence of dissolved oxygen in water is an important cause of corrosion. In order to make the unit run safely and stably, and to prevent the corrosion of boiler and steam turbine equipment, it is necessary to reduce the oxygen content of the feed water. In addition, the dissolved oxygen in the condensed water also affects the operation safety of the water supply system and the entire thermal system. When the condensed water with high ...
