Anti-freezing LNG (Liquefied Natural Gas) gasifying device and manufacturing method thereof

Abstract

The invention provides an anti-freezing LNG (Liquefied Natural Gas) gasifying device. The anti-freezing LNG gasifying device comprises a gasifying device buttress, a waterproof layer and a heat insulation layer, wherein a gap is formed on the surface of the gasifying device buttress and an exposing end of the gasifying device buttress is exposed in the air; the waterproof layer is paved on the surface of the exposing end of the gasifying device buttress; the waterproof layer is formed by coating the surface of the gasifying device buttress with a waterproof material and the gap is filled through the waterproof layer; the heat insulation layer is paved on the outer surface of the waterproof layer and the heat insulation layer is prepared from a heat insulation material; the anti-freezing LNG gasifying device can keep good utilization performance when being used under various environments.

Description

technical field [0001] The invention belongs to the field of chemical equipment, and in particular relates to a freeze-resistant LNG gasifier and a manufacturing method thereof, wherein the freeze-resistant LNG gasifier can maintain good performance when used in various environments. Background technique [0002] Liquefied natural gas (LNG) has become the main gas source or transitional gas source for cities that currently cannot use pipeline natural gas for gas supply, and it is also a supplementary gas source or peak shaving gas source for many cities that use pipeline natural gas for gas supply. As liquefied natural gas is more and more widely used in real life, the LNG gasification station also came into being. The LNG gasification station is a satellite station for receiving, storing and distributing LNG. To the user's middle adjustment place. LNG gasification stations have been gradually built in many small and medium-sized cities with developed economies and energy s...

AI Technical Summary

Problems solved by technology

Repeated cycles will cause the concrete to slowly crack and peel off, and the steel bars in the buttresses will also corrode without the protection of concrete, which greatly reduces the safety of the gasifier foundation

[0008] Of course, in the prior art, certain measures have been taken for the heat preservation of the gasifier, such as jacketed water heating, heating cables around the equipment pipes and simple insulation layers, and building sheds outside the equipment, etc., but the heat preservation effect of these measures Neither is good, that is to say, the antifreeze performance of the gasifier of the prior art still cannot meet the needs of actual life and production.
