Detailed knowledge of activated carbon fibre filters
Detailed knowledge of activated carbon fibre filtersI. Use environment and design of equipment1、Applicable temperature: ≤60℃ within normal temperature. 2、Applicable humidity: the lower the better ≤20%. 3、Designed line speed range: ≤2m/s. 4、Sorption and recovery wind speed: 0.2m/s--0.3 m/s. 5、Recommended gas residence time after ACF: ≥1 sec. 6、Absorption time: according to different concentrations, the air volume and air speed to decide. II. Calculation of ACF dosage by the known use environment 1、Working time: 8 hours/day. 2、Air volume: 10000 cubic meters/hour. 3、Absorption object: xylene. 4、Import concentration: 500 p.p.m./g. 5、Export concentration: 80 p.p.m./g. 6、First calculate the daily xylene volatilization: working time * air volume * (import concentration - export concentration) = 8 hours * 10000 cubic meters / hour * (500 - 80) p.p.g. = 33.6㎏. 7、Static adsorption rate of xylene adsorption is 45%. 8、Dynamic adsorption rate: 35%, i.e. 1㎏ ACF can adsorb 0.35㎏ xylene under dynamic working conditions. 9、The amount of xylene volatilized is 33.6㎏ per day, and the amount of ACF needed is calculated as 33.6/0.35㎏=96㎏. III. Scope of application of the equipment 1、The recovery device of organic solvent. 2、Purification of drinking water. 3、The removal of harmful and toxic gases. 4、Industrial occasions such as electronic and electrical materials, environmental protection industry, electronic industry, chemical industry, medical physiological health, etc. |
