Abstract

The invention discloses a steam generating method for preparing liquid air. The method is that a heat pump technology or pressurizing expansion is adopted to generate a heat source; a heat pump performs two-stage compression; a solenoid valve is utilized for selecting; a low-temperature compressor is used only at the initial stage, and a low-temperature compressor and a high-temperature compressor are synchronously used at the high-temperature stage, so that the energy efficiency ratio can be effectively increased; a steam-water separator is arranged, and thus the problem of water in air can be avoided; in addition, clean and non-pollution steam, boiled water, hot water and liquid air can be provided; the liquid air is prepared by recycling, cooling and thermally preparing, and therefore, energy conservation and emission reduction can be achieved, and the energy can be effectively utilized.

Description

technical field [0001] The invention relates to the technical field of preparing liquid air, in particular to a steam generation method capable of preparing liquid air. Background technique [0002] Air is a mixture of 78.01% nitrogen, 20.9% oxygen, and argon, neon, xenon, krypton and other rare gases. Liquid air is formed by liquefying air. Liquid air is a light blue liquid. The density is about 0.9. Boiling point -192°C (101.3 kPa, 760 mm Hg). It can be stored and transported in steel cylinders. Widely used as a source of oxygen. Air is compressed, cooled to a low temperature, and then expanded. There are many existing methods and devices for liquefying gas. No matter which method or device is used, a large amount of heat will be generated, and the heat will be taken away and lost by cooling water, which cannot achieve energy saving and emission reduction. Contents of the invention [0003] In view of the above-mentioned defects of the prior art, the present inven...
