The invention relates to a molten salt furnace tail gas heat exchanger with a preservative effect. The molten salt furnace tail gas heat exchanger with the preservative effect comprises a deaerator and a water-treatment device. The deaerator comprises a water outlet, a water inlet, a spent steam outlet and a steam inlet. The water outlet of the deaerator is connected with a water inlet of an economizer. The water inlet of the deaerator is connected with a water outlet of the water-treatment device through a pump. The spent steam outlet of the deaerator is connected with a condenser. The steam inlet of the deaerator is connected with a steam outlet of a smoke evaporator. Due to the fact that deaerator is additionally arranged, the molten salt furnace tail gas heat exchanger with the preservative effect is stable in deoxidization effect, is not only capable of eliminating oxygen, but also capable of eliminating carbon dioxide and nitrogen. Salt content is not increased in deoxidized water. Therefore, the molten salt furnace tail gas heat exchanger with the preservative effect is capable of utilizing self-produced steam to effectively avoid corrosion of equipment, is capable of saving energy, is capable of saving materials and prolonging service life of the equipment and possesses considerable economic benefit.
Description
technical field [0001] The invention relates to a heat exchanger for tail gas of molten salt furnace, in particular to a heat exchanger for tail gas of molten salt furnace with anti-corrosion function. Background technique [0002] Oxygen, nitrogen, carbon dioxide and other gases are often dissolved in industrial water. The presence of oxygen and carbon dioxide in them is very easy to corrode boilers and other equipment. Corrosion is especially severe in the presence of oxygen. The solubility of gas in water is different under different pressure and temperature, the higher the temperature of water, the lower its solubility. The traditional thermal deoxygenation method uses external steam to heat water to reduce the solubility of oxygen in it, so that the oxygen in the water can escape. The disadvantage is that it uses more steam. Contents of the invention [0003] The technical problem to be solved by the invention is: in order to remove oxygen and carbon dioxide and avo...
