An efficient way to remove oil

When thinking about the degreasing of compressed air, the most likely to think is the degreasing filter. Similar to this, like the degreasing filter, the degreasing effect is actually not very good, but there is an advantage that the price is relatively cheap. For small and medium-sized enterprises, such a small filter saves space and costs. But in fact, this is a misunderstanding. The filter element inside such an oil removal filter is physically adsorbed by the filter element. Most of the oil pollution is removed, but it will no longer work after being absorbed to a certain degree of saturation. The filter element needs to be replaced to ensure the quality of the compressed air. The replacement frequency is generally 3 to 4 months. The replacement time will also be determined according to different working conditions. This type of equipment is generally suitable for areas that do not require high compressed air.
Secondly, the highly clean compressed oil removal filter is the activated carbon filter. This type of equipment deeply adsorbs oil pollution through the adsorption method of activated carbon. This is still a physical adsorption process, but the oil removal effect of this type of filter is more efficient than that of the filter-type oil removal filter. It can achieve a 0-level oil-free state within the effective service life, and it is much more stable, and the price will be slightly lower. expensive. One disadvantage of this type of equipment is that it is prone to "oil poisoning." Oil poisoning means that when the adsorbed oil reaches a certain limit, the adsorbent will be contaminated by the oil, leading to loss of adsorption function and ultimately affecting the quality of compressed air. At this time, the adsorbent must be replaced before the oil can be removed again.
Finally, there is a relatively stable and efficient degreasing method, which is the degreasing method of catalytic oxidation. This type of degreasing equipment uses the special effect of the catalyst, which can produce a catalytic oxidation reaction under certain conditions. The process of chemical reaction, and this kind of equipment has no loss of raw materials, the core material is the catalyst. The catalyst only acts as a catalyst and does not react by itself, so it is relatively stable and can stably remove the oil content in the compressed air up to 0.001mg/m³, which also fills a gap in the market for stable oil removal equipment. The only disadvantage is that the initial investment cost is relatively high, but if you purchase an oil-free air compressor, in addition to the purchase cost, there is also a maintenance cost, which is better than such an oil removal equipment plus an ordinary oil-containing air compressor. This cost is much lower.
