Description

Technical Field

[0001] The utility model relates to the technical field of molecular sieve drying, in particular to a rapid drying device for preparing molecular sieves. Background Art

[0002] Carbon molecular sieve is a new type of adsorbent developed in the 1970s. It is an excellent non-polar carbon material. Carbon molecular sieve for nitrogen production is used to separate air-enriched nitrogen. It adopts a normal temperature and low-pressure nitrogen production process. Compared with the traditional deep cold and high-pressure nitrogen production process, it has the advantages of less investment cost, faster nitrogen production speed, and lower nitrogen cost. Therefore, it is the preferred pressure swing adsorption air separation nitrogen-enriched adsorbent in the engineering industry. This nitrogen is widely used in the chemical industry, petroleum and natural gas industry, electronics industry, food industry, coal industry, pharmaceutical industry, cable industry, metal heat treatment, transportation and storage.

[0003] Most existing molecular sieve drying devices use rotary stirring to improve the drying effect during use. However, the molecular sieve will become brittle due to the increase of internal moisture during the drying process. Moreover, the molecular sieve may be broken during the stirring process, making it difficult to carry out subsequent processing of the broken molecular sieve or directly causing the broken molecular sieve to be unable to be processed subsequently.
