Problems solved by technology

[0003] Nitrogen is usually liquefied into liquid nitrogen for easy storage and transportation, and then let it absorb heat and vaporize for use when in use. At present, the existing liquid nitrogen vaporization devices generally have incomplete vaporization, and the utilization rate of the heat exchange medium in most vaporization devices is Not high, can not achieve recycling, causing waste of resources

Abstract

The invention discloses a liquid nitrogen vaporizer. An inner cavity is arranged in a vaporizer body, an upper cover is welded at the upper end of the inner cavity, a threaded hole is formed in the middle of the upper cover, a sealing ring is arranged on the upper portion of the upper cover, a flange plate is arranged on the upper portion of the sealing ring, a spiral pipe is wound around the outer surface of the inner cavity, the lower end of the spiral pipe communicates with the bottom of the lower end of the inner cavity and is welded and fastened on the outer wall of the inner cavity, a through hole is formed in the edge of the upper cover, the upper portion of the spiral pipe is provided with a through hole in a sleeve fit mode, the spiral pipe is welded on the upper cover, and a nitrogen outlet is formed in the upper end of the spiral pipe. According to the vaporizer, nitrogen is gradually vaporized from bottom to top through the spiral pipe, so that the vaporization of the liquid nitrogen is more sufficient, the efficiency is higher, a heat exchange medium liquid and a heat exchange circulation device are used for circularly vaporizing the liquid nitrogen, the phenomenon ofwaste of a cooling medium is effectively avoided, and resources are saved.

Description

technical field [0001] The invention relates to a vaporization device, in particular to a liquid nitrogen vaporizer. Background technique [0002] Although nitrogen is more than oxygen in the atmosphere, because of its inactive nature, people only know nitrogen after they know oxygen. Due to the chemical inertness of nitrogen, it is often used as a protective gas to prevent certain objects from being oxidized by oxygen when exposed to the air. Filling the granary with nitrogen can prevent the grain from being moldy or germinating, and can be stored for a long time. Liquid nitrogen can also be used as a deep cryogen. As a cryogen, it is often used in hospitals for speckle removal, bags, beans, etc., and high-purity nitrogen is used as a carrier gas for chromatographs and other instruments. [0003] Nitrogen is usually liquefied into liquid nitrogen for easy storage and transportation, and then let it absorb heat and vaporize for use when in use. At present, the existing liqu...
