Abstract

The invention is applicable to the related technical field of nitrogen making equipment, and provides a molecular sieve adsorption tower used in nitrogen making equipment, which comprises a main tower body, a molecular sieve adsorption assembly is arranged in the main tower body, and the molecular sieve adsorption assembly comprises two symmetrically arranged first baffles fixedly connected in the main tower body, the interior of the main tower body is fixedly connected with a power motor through a plurality of first connecting rods, the output end of the power motor is fixedly connected with a first rotating shaft, and each group of third baffles is connected with a molecular sieve adsorption plate through a connecting unit. The power pump conveys gas into the main tower body through the gas inlet for molecular sieve adsorption operation, the gas reaches the molecular sieve adsorption plates through the through holes formed in the first barrier plate for molecular sieve adsorption operation, and when the molecular sieve adsorption plate on one side needs to be replaced, the box door is opened, and the box door is opened. The molecular sieve adsorption plate on the non-working side is taken down through the connecting unit, and normal operation is not affected.

Description

technical field [0001] The invention belongs to the technical field of nitrogen making equipment, and in particular relates to a molecular sieve adsorption tower used in nitrogen making equipment. Background technique [0002] Nitrogen, chemical formula N 2 , is a colorless and odorless gas. Nitrogen is chemically inactive. It can react with hydrogen to form ammonia under high temperature and high pressure and catalyst conditions; it can combine with oxygen to form nitric oxide under the condition of discharge; even active metals such as Ca, Mg, Sr and Ba are only available in It can only react with heating, and the high chemical stability of nitrogen is related to its molecular structure. [0003] Now, the spacer type carbon molecular nitrogen generator adsorption tower will be used for the production of nitrogen. The molecular sieve adsorption tower is indispensable in the process of nitrogen production, and its function and structure directly have an important impact on...
