An integral brazed tube bundle type self-supporting air-cooled condenser

Abstract

The present invention relates to the technical field of condensers, in particular to an integrally brazed tube bundle type self-supporting air-cooled condenser, which includes a shell, and an air-cooling cavity is axially penetrated in the shell, and a utility A tube bundle mechanism for condensing cylinder exhaust steam into water, the tube bundle mechanism includes condensing tubes and fins for heat transfer, and a blower mechanism for blowing air into the air-cooled cavity is installed on one axial end of the housing . In the present invention, the tube bundle mechanism for condensation is installed in a cylindrical casing with openings at both ends, and a blower mechanism is used to blow air into the casing on one side of the casing, and then the air enters the casing and is discharged from the opening on the other side. A unidirectional airflow is formed to realize the air cooling effect on the tube bundle mechanism, and the wind generation efficiency is high, and it also isolates the influence of rain, snow and strong wind from other directions outside.

Description

technical field [0001] The invention relates to the technical field of condensers, in particular to an integral brazed tube bundle type self-supporting air-cooled condenser. Background technique [0002] The condenser is an important part of the condensing steam turbine device, and its working performance directly affects the thermal economy and operational reliability of the entire device. The condenser performs the task of cold source in the steam turbine device, and the system will The exhaust steam of the steam turbine condenses into water and takes away the heat released when the steam condenses. There are two types of condensers: water-cooled condensers and air-cooled condensers. [0003] Air-cooled condensers generally use fans to pass horizontally outside the tube bundle or to ventilate naturally, while steam flows in the tube bundle and is condensed into water. In the prior art, the space between the tube bundle and the fan of many air-cooled condenser products is r...

AI Technical Summary

Problems solved by technology

[0003] Air-cooled condensers generally use fans to pass horizontally outside the tube bundle or to ventilate naturally, while steam flows in the tube bundle and is condensed into water. In the prior art, the space between the tube bundle and the fan of many air-cooled condenser products is relatively open. It is easily affected by the ambient temperature, rain, snow and strong wind, and it is also prone to the problem of hot air recirculation. Due to the low specific heat of the air and the susceptibility to interference, the fans generally need to be large, which will cause the problem of high noise
