Description
Technical Field
The utility model relates to a water bath type reheater field especially relates to a water bath type reheater of adopting U-shaped heat exchange tube.
Background
The water bath type reheater is used for heating the relatively cold gas by 60-70 ℃ water in the water bath type reheater, and the gas is converted from a low-temperature gas state to a normal temperature, so that the gas supply amount is sufficient, and the pressure is stable. Because the water bath type reheater consumes more energy, aiming at the reality, the water bath type reheater needs to fully absorb heat as much as possible and reduce energy consumption.
The principle is that the heat exchange is carried out through physical heat exchange: when the low-temperature gas passes through the heat exchange tube from the inlet, the low-temperature gas exchanges heat with water heated by a heat source, so that the low-temperature gas is converted into a normal-temperature gas state and reaches the outlet. In the process, because the temperature difference of the inlet and the outlet of the heat exchange tube is large, the expansion with heat and the contraction with cold are obvious, and the requirements on the properties of the heat exchange tube material, such as ductility, elongation, thermal expansion coefficient and the like, are relatively high. Especially, the bending position of the heat exchange tube needs to be reasonably designed. At present, straight pipes and bent pipes are assembled and welded in most forms in the market, and the straight pipes and the bent pipes exist in a single-in single-out form. Not only the welding process is tedious, the cost is wasted, but also the welding quality of the welding joint can not be ensured, so that the product quality can not be better ensured.
