Example Embodiment

[0033] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described below with reference to the accompanying drawings and specific examples. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0034] The directional terms mentioned in the present invention, such as "up", "down", "left", "right", "front", "rear", "inside", "outside", etc., are only with reference to the drawings. direction. Therefore, the directional terms are used to describe and understand the present invention, rather than to limit the present invention.

[0035] like Figure 1-Figure 7 and Figure 9 As shown, an air rewarming type LNG vaporizer includes a casing 4, a heat exchange core 5 is fixedly arranged in the casing 4, and the upper part of the left end surface of the casing 4 is connected with a Venturi ...

Abstract

The invention discloses an air rewarming type LNG vaporizer which comprises a shell. A heat exchange core is fixedly arranged in the shell, the upper portion of the right end face of the shell sequentially communicates with a venturi type fluid distributor and an LNG inlet pipe through flanges, and the lower portion of the right end face of the shell communicates with a cold air outlet pipe connector; and the upper portion of the left end face of the shell communicates with an NG outlet pipe connector, and the lower portion of the left end face of the shell sequentially communicates with a venturi type fluid distributor and a hot air inlet pipe through flanges. The air rewarming type LNG vaporizer solves the problem of performance deterioration of a heat exchanger roughly due to low heat exchange efficiency and large flow resistance caused by factors such as local flow channel resistance and poor inlet flow channel distribution of a traditional LNG vaporizer, and the air rewarming typeLNG vaporizer is simple in structure, convenient to machine and easy to clean, greatly improves the heat exchange efficiency of the heat exchanger, and prolongs the service life of the heat exchanger.

Description

technical field [0001] The invention relates to the technical field of radiators, in particular to a novel air reheating type LNG vaporizer and a working method thereof. Background technique [0002] Natural gas (NG) is generally transported in the form of liquefied natural gas (LNG). However, in actual use, whether it is used for industrial energy demand or for civil gas, liquefied natural gas (LNG) often needs to be reheated to Use after gaseous state at room temperature. As an inexpensive low-grade heat source, air has the advantages of low operation and maintenance costs, easy access, and no energy and power consumption. It is widely used in LNG vaporizers used in base-load systems. [0003] There are also many problems in the heat transfer process of the LNG vaporizer, such as uneven distribution of fluid in the flow channel: due to the local resistance of the flow channel (such as the flow resistance of some channels is too high), the distribution of the inlet flow ch...
