Pressure swing adsorption nitrogen production equipment with screening and filtering effects and nitrogen production process

Abstract

The invention provides pressure swing adsorption nitrogen production equipment with screening and filtering effects and a nitrogen production process. The pressure swing adsorption nitrogen productionequipment comprises a base, an air pump is arranged on the base, a screening and filtering box is arranged on one side of the air pump, an air suction pipe is installed on an air suction opening of the air pump, and the end, away from the air pump, of the air suction pipe communicates with the top of the screening and filtering box; an electric heating wire is arranged at the top of an inner cavity of the screening and filtering box, a moisture absorber is arranged below the electric heating wire, a particle filter screen is arranged below the moisture absorber, and a vibration motor is installed at the bottom of the particle filter screen. The pressure swing adsorption nitrogen production equipment can effectively filter moisture and dust particles in air, can perform fineness screeningand collection on the filtered dust particles, is high in screening efficiency, facilitates subsequent treatment of particle dust with different fineness, can increase the nitrogen conveying rate of the nitrogen discharge pipe through the design of the piston, meanwhile, when the gas collecting base is blocked, nitrogen conveying is stopped in time, the gas collecting base is prevented from exploding, and certain safety is achieved.

Description

technical field [0001] The invention relates to the technical field of nitrogen preparation, in particular to pressure swing adsorption nitrogen production equipment and a nitrogen production process with screening and filtering effects. Background technique [0002] At present, the commonly used nitrogen production methods mainly include cryogenic distillation, pressure swing adsorption and membrane separation. [0003] The patent document (CN201822023327.7) discloses a pressure swing adsorption nitrogen production equipment, which can effectively provide installation space for nitrogen production equipment by setting a base, and can effectively compress clean air through an air compressor. Therefore, it is sent to the combined filter, and the impurities in the compressed air can be further filtered through the combined filter, so as to provide the purity of the raw material, and then sent to the pressure swing adsorption nitrogen generator through the input pipe. Through ...

AI Technical Summary

Problems solved by technology

However, the pressure swing adsorption nitrogen generating equipment cannot effectively filter the moisture and dust particles in the air

At the same time, the pressure swing adsorption nitrogen production equipment cannot screen and collect dust particles of different fineness, and the nitrogen delivery efficiency is not high. When there is a blockage, it is prone to explosion.
