Abstract
The present invention relates to a heat exchanger containing the steam of non-condensing gas in condensation, which comprises vertical and alternated pipe bundles composed of a plurality of heat exchanging gas pipes and inlet collecting pipes of steam and non-condensing gas. One end of each pipe is connected with the inlet collecting pipes, and the steam and the non-condensing gas are accepted in a parallel mode. The other end of each pipe is connected with an independent collecting pipe relevant to the pipe bundles. The independent collecting pipe discharges the non-condensing gas into the atmosphere. Each pipe bundle is provided with the independent collecting pipe to prevent the pressure among the pipe bundles from being balanced, and the non-condensing gas in the pipe from backward flowing to form a gas bag. The pipe bundles and a horizontal surface are inclined. The independent collecting pipe is higher than each inlet collecting pipe. The non-condensing gas in the pipe bundle rapidly rises to enter the independent collecting pipe, and particularly when the gas is lighter than the steam; thus, the non-condensing gas can be easily discharged when condensed substances downward flow into the inlet collecting pipes.
