Liquid nitrogen vaporization device

Abstract

The invention provides a liquid nitrogen vaporization device. The liquid nitrogen vaporization device comprises a low-temperature container, a low-temperature liquid nitrogen pump, a vaporizer and a high-pressure gas cylinder. The low-temperature container is a horizontal vacuum heat insulation low-temperature container, the design pressure is 0.8 MPa, the low-temperature container comprises an inner barrel body and an outer barrel body, the inner barrel body is fixed to the outer barrel body through a stainless steel sling, and a middle interlayer is filled with pearlife. The low-temperatureliquid nitrogen pump is a horizontal double-row piston pump of 45-50 MPa, the vaporizer is a room temperature type vaporizer of 45-50 MPa, an inner casing pipe is a stainless steel pipe, the tail of aheat exchange finned tube is made of an aluminum alloy, and the high-pressure gas cylinder is an S-type seamless structural steel cylinder of 45-50 MPa. The liquid nitrogen vaporization device provided by the invention mainly achieves nitrogen supply under various working conditions, has the characteristics of being flexible, safe, reliable and easy to operate, can meet the gas supply requirements of various industries and is especially used for nitrogen in remote areas conveniently.

Description

technical field [0001] The invention relates to a liquid nitrogen vaporization device, in particular to a skid-mounted liquid nitrogen vaporization device. Background technique [0002] Liquid nitrogen is nitrogen in a liquid state. Liquid nitrogen can be produced by special equipment, or it can be obtained as a by-product in the process of producing liquid oxygen. With the rapid development of my country's aerospace, energy, chemical industry, military and other fields, the demand for high-pressure nitrogen is increasing year by year. The traditional supply of nitrogen is mainly to build a high-pressure nitrogen production system on the spot or use high-pressure cylinder trucks for transportation. The former The investment is large and the effect is slow, while the latter has low transportation efficiency and poor stability, which has gradually failed to meet the development needs of various industries. [0003] In this context, in order to achieve fast and efficient high-p...
