Abstract

A separator for preparing nitrogen is provided. The separator comprises a cavity, a gas feeding path, a gas discharging path and carbon molecular sieve layers, wherein the gas feeding path is disposed at the bottom of the separator, the gas discharging path is disposed at the top of the separator, the carbon molecular sieve layers comprise a first carbon molecular sieve layer, and the first carbon molecular sieve layer is disposed in the cavity of the separator in a laminated manner. Through the technical scheme, separation effects of the carbon molecular sieve layers of the separator can be effectively improved, the nitrogen production efficiency is increased, the separator is simplified, nonuniform pressure in the cavity is prevented, and the separator is small in size and convenient to dismount and maintain.

Description

technical field [0001] The invention belongs to the technical field of producing nitrogen, and in particular relates to a separator and a system for producing nitrogen. Background technique [0002] Existing nitrogen production devices generally use high-quality carbon molecular sieves as adsorbents, and use the principle of pressure swing adsorption to directly obtain nitrogen from compressed air; under a certain pressure, due to dynamic effects, the diffusion rate of oxygen and nitrogen on carbon molecular sieves The difference is large. In a short period of time, oxygen molecules are adsorbed by carbon molecular sieves, and nitrogen molecules are enriched in the gas phase to achieve the separation of oxygen and nitrogen. However, the carbon molecular sieve layer of the existing separator has obvious differences in the adsorption capacity of oxygen with the change of pressure, so that the efficiency of nitrogen production is not high; the utilization rate of the carbon mol...
