一种空气深度干燥装置

Air degree of depth drying device

Abstract

本实用新型提供一种空气深度干燥装置,包括按空气流通方向依次连接的空气压缩机、冷干机、纯化系统和冷箱,所述冷箱内设置有主换热器、透平膨胀机和霜雪捕集器,纯化系统、主换热器、透平膨胀机和霜雪捕集器按空气流通方向依次连接,霜雪捕集器和主换热器之间设置有空气复温管道,用于将经过霜雪捕集器的空气复热至常温,得到露点为-80℃以下的深度干燥空气,主换热器与深度干燥空气出管连接。本实用新型可以将空气的露点降到-80℃~-100℃,满足对空气干燥度有更高要求的技术领域。
The utility model provides an air degree of depth drying device, include the air compressor who connects gradually according to the circulation of air direction, cold machine, hydrogen purification system and the cold box done, be provided with main heat exchanger, turboexpander and frost and snow trap in the cold box, hydrogen purification system, main heat exchanger, turboexpander and frost and snow trap connect gradually according to the circulation of air direction, are provided with air rewarming pipeline between frost and snow trap and the main heat exchanger for the air that will pass through the frost and snow trap is warm to normal atmospheric temperature again, obtains the dew point and goes out the pipe connection for the degree of depth dry air below - 80 DEG C, main heat exchanger and degree of depth dry air. The utility model discloses can arrive - 80 DEG C - - 100 DEG C with the depoint depression of air, satisfy the technical field who has requirements at the higher level to the air drying degree.
