Abstract
The utility model discloses an anti-corrosion system for a tube bundle of a reboiler at the bottom of a sewage stripping tower. The anti-corrosion system comprises the reboiler, the stripping tower, a sewage conveying pipeline, a clean liquid pipeline and a precipitate collector, a plurality of drain outlets and a heat exchange inlet are formed in the bottom of the reboiler, and a heat exchange outlet is formed in the top of the reboiler; a liquid extraction opening is formed in the bottom of the stripping tower and is connected to the heat exchange inlet through a pipeline; a liquid inlet is formed in the middle upper part of the side wall of the stripping tower and is connected to the heat exchange outlet through a pipeline; each sewage outlet corresponds to one sewage conveying pipeline and one sediment collector; the sewage outlet is connected to a sewage inlet of the sewage conveying pipeline, a sewage outlet of the sewage conveying pipeline is connected to a sewage inlet of the sediment collector, and a clean liquid outlet of the sediment collector is connected to the liquid inlet through the clean liquid pipeline. The problem that in the prior art, tar powder is deposited on a heat exchange tube of a reboiler, so that the heat exchange tube of the reboiler is corroded is solved.
