Cut-in oxygen purification device

Abstract

The invention discloses a cut-in oxygen purification device. The cut-in oxygen purification device includes a device body; the device body is mainly composed of a gas inlet, a gas outlet, a rotationalflow zone, a drying zone, a carbon dioxide removal zone, a nitrogen catalytic-adsorption zone and a buffer zone; the gas inlet is formed in the bottom of the left side wall of the device body, the gas outlet is formed above the right side wall of the device body, the rotational flow zone, the drying zone, the carbon dioxide removal zone, the nitrogen catalytic-adsorption zone and the buffer zoneare separated through partitions, the drying zone, the carbon dioxide removal zone and the nitrogen catalytic-adsorption zone are internally provided with lifting devices, the tops of the liftin devices are fixedly connected with abutting plates, the bottoms of the abutting plates are provided with annular plates, the nitrogen catalytic-adsorption zone is communicated with the drying zone througha communication pipe, the communication pipe is provided with a one-way valve, a rotating shaft is arranged in the rotational flow zone, and the surface of the rotating shaft is fixedly connected withrotating blades. According to the device, the purification efficiency is high, the oxygen purification effect is good, and the purification effect of oxygen is further improved through circular processing.

Description

technical field [0001] The invention relates to the field of oxygen production and processing, in particular to a cut-in oxygen purification device. Background technique [0002] Oxygen is widely used in the industrial field, and the application of oxygen involves all walks of life. [0003] According to the difference in the boiling point of oxygen and nitrogen in industry, the air separation equipment is used to produce oxygen; first, the air is dedusted and purified to remove carbon dioxide and water vapor, and then pressurized at low temperature to liquefy the air; by controlling the temperature to evaporate liquid air, the boiling point is lowered The low liquid nitrogen evaporates first, and the rest is liquid oxygen with a higher boiling point. [0004] This method can be used to prepare oxygen on a large scale to meet the needs of industrial development; however, the purity of the prepared oxygen is low, and the oxygen contains impurity gases such as water vapor, ca...

Problems solved by technology

[0004] This method can be used to prepare oxygen on a large scale to meet the needs of industrial development; however, the purity of the prepared oxygen is low, and the oxygen contains impurity gases such as water vapor, carbon dioxide gas, and nitrogen, so oxygen needs to be further processed and purified to prepare high purity oxygen
