Description

Technical Field

[0001] This utility model relates to the field of heating devices, and in particular to a heating device for feeding a water vapor stripping tower. Background Technology

[0002] Stripping is a unit operation used to recover absorbed solutes and separate the absorbent from the solute for regeneration. In some cases, stripping is also used to remove light components from liquids, such as in the oil refining industry where steam is often used as a stripping agent to remove light components from oil products. Therefore, stripping can be used in conjunction with absorption or alone. Stripping towers can be plate towers or packed towers. Regardless of the tower type, the feed enters from the top and exits from the bottom; the desorbent enters from the bottom, contacts the liquid feed countercurrently, and exits from the top along with the stripped components. Unlike absorption towers, the concentrated end is at the top and the dilute end is at the bottom. In stripping towers, the equilibrium partial pressure of the solute in the liquid phase is greater than that in the gas phase. During stripping, the solute molecules need to be converted into gas, making it an endothermic process. Therefore, the stripping agent temperature is generally equal to or greater than the feed temperature; otherwise, the stripping effect will be reduced.

[0003] In the operation of stripping towers, steam is often used as a stripping agent to remove light components from liquid materials and to assist in the separation of absorbents from melting, or to heat the feed material during feeding. However, most existing steam generators suffer from improper exhaust speed, which affects the heat exchange and slows down the heating rate. Furthermore, they have high energy requirements during use and are not energy-efficient or environmentally friendly. Therefore, a heating device for feeding water stripping towers is proposed.
