Liquid oxygen condensing and vaporizing device

Abstract

This invention provides a liquid oxygen condensation and vaporization device, including a vaporization unit comprising a heat dissipation pipe, a flow channel formed inside the heat dissipation pipe, an air inlet pipe inside the heat dissipation pipe, and a first guide channel formed at one end of the heat dissipation pipe, which is connected to the air inlet pipe. Multiple air inlet pipes are provided. This invention is rationally designed. By providing air inlet pipes inside the flow channel, external gas can enter through the air inlet pipes, allowing the gas to flow through the liquid oxygen in the middle of the flow channel, rapidly heating the liquid oxygen and enabling simultaneous vaporization of the liquid oxygen in the middle and outer parts of the flow channel. Furthermore, the multiple heat dissipation pipes allow the liquid oxygen to be discharged through heat dissipation pipes at different locations, preventing hydraulic fluid from accumulating and affecting its vaporization.

Description

Technical Field

[0001] This utility model mainly relates to the field of liquid oxygen condensation and vaporization, and specifically to a liquid oxygen condensation and vaporization device. Background Technology

[0002] Liquid oxygen, as an important industrial gas and propellant, is widely used in steel smelting, chemical synthesis, medical oxygen supply, aerospace, wastewater treatment, and metal cutting due to its high density and ease of storage and transportation. However, liquid oxygen exists in an extremely low-temperature liquid state (approximately -183°C) at atmospheric pressure, while most end-use equipment requires gaseous oxygen at room temperature (or near room temperature). Therefore, the efficient, safe, and stable conversion of liquid oxygen into gaseous oxygen at the required pressure and temperature is an indispensable and critical link in the liquid oxygen supply chain. This process is typically accomplished by a "vaporizer" or "gasifier."

[0003] During the operation of specific embodiments, the inventors discovered the following defects:

[0004] However, when liquid oxygen flows inside the vaporizer, the larger diameter of the internal pipes causes the liquid oxygen on the periphery to vaporize at a faster rate than that in the middle, resulting in uneven vaporization.

[0005] It should be noted that the above content falls within the scope of the inventor's technical knowledge. Due to the vast and complex nature of the technical content in this field, the above content of this application does not necessarily constitute prior art. Utility Model Content
