Embodiment Construction

[0019] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0020] Such as Figure 1 to Figure 2As shown, a high-efficiency compact LNG vaporizer includes a shell 1 and a heat exchange core 2. The shell 1 is a six-petal flower-shaped cylinder with a cavity. The inflow and outflow ports of the heat exchange medium; the heat exchange core 2 is composed of several groups, each group consisting of 4 stacked regular hexagonal veneers, any of the regular hexagonal veneers corresponds to the There are several grooves on one plane, and each group of 4 regular hexagonal veneers is staggered and stacked at 60° relative to the groove mouth, and they are stacked and connected in the housing 1. The six corners of the regular hexagonal veneers are connected to the The casing 1 is connected by welding to form six mutually independent vertical airtight cavities corresponding to the ...

Abstract

The invention discloses a high-efficiency compact type LNG carburetor. The high-efficiency compact type LNG carburetor comprises a shell and a heat exchange core body, the shell is a hexapetalous-flower-shaped cylinder with a cavity, cambered surfaces of the hexapetalous-flower-shaped cylinder are respectively provided with inflow openings and outflow openings used for heat exchange media, the heat exchange core body is formed by a plurality of groups of laminated regular hexagonal single boards, each group is formed by 4 regular hexagonal single boards, a plane between any corresponding two edges of the regular hexagonal single board is provided with a plurality of channels, opposite channel openings of the 4 regular hexagonal single boards in each group form 60 degrees and tightly attached and laminated in the shell in a staggered manner, and six corners of the regular hexagonal single boards are connected with the shell in a welding manner to form six mutually independent vertical sealed cavities respectively corresponding to the inflow openings and the outflow openings. According to the high-efficiency compact type LNG carburetor, heat exchange of three heat exchange media in the same carburetor is accomplished, the heat exchange area of the carburetor is increased, the work pressure and the vaporization efficiency for the operation of the LNG carburetor are increased, and the size and the weight of the LNG carburetor are reduced.

Description

technical field [0001] The invention relates to a vaporizer, more specifically, relates to a high-efficiency and compact LNG vaporizer with multi-media fine channels. It belongs to the technical field of heat transfer enhancement. Background technique [0002] LNG vaporizer is the core equipment to realize the storage and transportation of liquefied natural gas to the use of gaseous natural gas. The equipment can be placed both onshore and offshore. However, the construction of onshore LNG gasification stations faces more serious constraints, such as large space occupation, difficulty in moving, and inherent danger of handling LNG, which also makes nearby residents very repulsive. Therefore, in many cases, an offshore LNG vaporization station is considered a better solution for a fast-track supply of natural gas. Whether it is an onshore LNG vaporization station or an offshore LNG vaporization station, the vaporizer is the key equipment in the LNG vaporization system to r...
