Nitrogen production device by pressure swing adsorption

Abstract

The invention discloses a nitrogen production device by pressure swing adsorption, and belongs to the technical field of nitrogen production. The nitrogen production device includes a housing and an intake valve installed at one end of the outer side of the housing, a fixing plate is installed at the position, near the intake valve, in the housing, a dust filter screen is arranged at the bottom, on the outer side of the fixing plate, in the housing, a buffer assembly is arranged on the side, facing the intake valve, of the fixing plate, the outer side of the dust filter screen is fixed to thehousing, a partition plate is installed at the bottom of the housing, groove bodies are fixedly formed in the inner side of the partition plate and the outer side of the dust filter screen, and the partition plate including the dust filter screen and the housing structure are filled with distilled water. According to the nitrogen production device by pressure swing adsorption, by opening the intake valve to introduce mixed gas into the housing, the high-pressure mixed gas collides and buffers with the buffer assembly on the fixing plate, the buffered mixed gas passes through the dust filter screen and enters the distilled water of the partition plate including the dust filter screen and the housing structure for dust removal, the good dust removal action is achieved, and thus the nitrogenproduction device by pressure swing adsorption can better provide pure nitrogen.

Description

technical field [0001] The invention relates to nitrogen preparation equipment, in particular to a pressure swing adsorption nitrogen production device, which belongs to the technical field of nitrogen production. Background technique [0002] Nitrogen, with the chemical formula N2, is a colorless and odorless gas under normal conditions. Generally, nitrogen is less dense than air. Nitrogen accounts for 78.08% (volume fraction) of the total atmosphere. It is one of the main components of air. At standard atmospheric pressure When nitrogen is cooled to -195.8°C, it becomes a colorless liquid, and when cooled to -209.8°C, liquid nitrogen becomes a snow-like solid. The chemical properties of nitrogen are inactive, and it is difficult to react with other substances at room temperature. So it is often used to make preservatives. However, under high temperature and high energy conditions, it can undergo chemical changes with certain substances to produce new substances useful to ...

Problems solved by technology

[0003] In the process of adsorption nitrogen generation in the current pressure swing adsorption nitrogen generation device, there will often be a large amount of dust that is not easy to filter, and the filtration process of the current adsorption nitrogen generation device is not sufficient, and the buffering of the high-pressure mixed gas entering it is not enough.
