Foreword
This standard was drafted in accordance with the rules given in GB/T 1.1-2009.
This standard replaces GB/T 12919-1991 "marine control air purification device." Compared with GB/T 12919-1991, the main technology
The changes are as follows.
--- Modify the name of "marine control air purifier technical conditions";
--- Cancel the "terminology" chapter (see.1991 edition Chapter 3);
--- Increased rated flow range (see 3.2.1 and 3.2.2,.1991 version 4.2.1 and 4.2.2);
--- Modify the value of intake pressure (see 3.2.1 and 3.2.2,.1991 version 4.2.1 and 4.2.2);
--- Increased pressure dew point requirements (see 3.2.1 and 3.2.2);
--- Added "design and structure" (see 4.1);
--- Added "appearance quality" (see 4.2);
--- Modify the atmospheric pressure dew point, pressure drop, the level of solid particles and oil content requirements (see 4.3.2.4.3.3.4.4.4.4.3.5,.1991
Version 4.2.1 and 4.2.2);
--- Increased noise requirements (see 4.3.8);
--- Modify the "Dielectric Strength" requirement (see 3.9.3,.1991 version 5.11);
--- Modify the "insulation resistance" requirements (see 4.3.10,.1991 version 5.10);
--- Revised "environmental adaptability" requirements (see 4.4,.1991 version 5.9);
--- Modify the strength test and tightness test dwell time values (see 5.3.7 and 5.3.8,.1991 version 6.3.2 and 6.3.3).

3 categories
3.1 type
According to the purification device using different drying methods, the purification device is divided into.
a) Freeze-type decontamination unit. Compress air is cooled to its dew point by refrigeration equipment to separate the moisture in the compressed air, dried
After the compressed air and then through the precision filter to remove impurities, get clean compressed air;
b) adsorption purification device. The use of adsorbent to absorb moisture in the compressed air, compressed air after drying and then through a precision filter
Exclude impurities, get clean compressed air.
3.2 Specifications
3.2.1 Freezing purification device specifications in Table 1.
