Embodiment Construction

[0012] The air-temperature type LNG vaporizer involved in the present invention, such as figure 1 and figure 2 As shown, it includes a frame and finned tubes, the finned tubes are arranged in parallel to form an array, and the finned tubes are divided into two arrays, namely 8-finned tubes and 12-finned tubes, the finned tubes are The tube has a built-in spiral guide.

[0013] Further, the finned tube adopts a built-in liquid-absorbing core, and the built-in liquid-absorbing core is a stainless steel belt. At this time, due to the capillary phenomenon of the surface tension of the liquid, the liquid in the liquid film is adsorbed in the narrow gap between the liquid-absorbing core and the inner wall of the finned tube, and the liquid in the liquid film absorbs heat and gasifies to form tiny bubbles. When the tiny bubbles flow upward and When the larger bubbles are formed, they escape from the small holes on the upper surface of the liquid-absorbing core, and finally detach ...

Abstract

The invention relates to an air temperature type LNG gasifier. The air temperature type LNG gasifier comprises a frame and finned tubes, the finned tubes are arranged in parallel to form arrays, the finned tubes are divided into two arrays including eight-fin fin tubes and 12-fin finned tubes, and spiral flow guide parts are arranged in the finned tubes. The gasifier is good in heat exchange effect and small in size.

Description

technical field [0001] The patent of the invention relates to an air-temperature LNG gasifier, which belongs to the technical field of liquefied natural gas. Background technique [0002] The construction and development of LNG (liquefied natural gas) receiving terminals has been going on for quite a long time, and they are mainly distributed in land and coastal areas. In recent years, with the enhancement of people's awareness of environmental protection and safety, LNG receiving terminals have gradually developed in the direction of environmental protection, economy, safety and flexibility, from the traditional land to sea. The LNG gasifier is the core heat transfer equipment of the receiving terminal. At present, the types of gasifiers commonly used in LNG receiving stations include open-frame gasifiers, submerged combustion gasifiers, intermediate medium gasifiers and air-temperature gasifiers. [0003] Air-temperature vaporizer is a heat exchange equipment commonly us...
