Integral brazing tube bundle type self-supporting air cooling condenser

Abstract

The invention relates to the technical field of condensers, in particular to an integral brazing tube bundle type self-supporting air cooling condenser which comprises a shell. An air cooling cavity is formed in the shell in an axial penetrating manner, a tube bundle mechanism used for condensing steam exhausted by a cylinder into water is arranged in the air cooling cavity, and the tube bundle mechanism comprises a condensing tube and fins used for heat transfer; and an air blowing mechanism for blowing air into the air cooling cavity is mounted at one axial end of the shell. According to the integral brazing tube bundle type self-supporting air cooling condenser, the tube bundle mechanism for condensation is installed in the barrel-shaped shell with openings in the two ends, the air blowing mechanism is used for blowing air into the shell from the opening in one side of the shell, then air enters the shell and is discharged from the opening in the other side to form unidirectional airflow, the air cooling effect on the tube bundle mechanism is achieved, the air generation efficiency is high, and the influence of rain, snow and strong wind in other directions outside is also isolated.

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
