的袋式除尘器的运行过程中，因为粉尘含有相对高量的水和有粉尘的油，湿润吸收，易潮解的功能，它很可能是水膜将形成的粉尘的表面上 从而改善其附着的能力。 显然，这是用于粉末集尘很有帮助。 但是，它也带来困难除灰，尤其是在与高温气体是在高湿度的状态下，冷凝现象会发生，因为外部的气体的冷却。 其结果是，所收集的粉尘将缩放的过滤介质的表面上以引起堵塞，而且也影响的除尘设备的正常运行。 防水和耐油针刺毡可有效防止水渗透，不同种类的油污秽的附件。 与普通的过滤介质相比，它具有防油的质量，以及粘附性和易于分离。

During the functioning of bag dust collector, because powder dust contains a relatively high amount of water and there is powder dust with the features of oil, moister-absorption and easy deliquescence, it is likely that water film will form on the surface of powder dust so as to improve its ability of attachment. Obviously, this is helpful for powder dust collection. However, it also poses difficulty for ash removal, especially when gas with high temperature is in the state of high moisture, condensation phenomenon will arise because of the cooling of external gas. As a result, the collected powder dust will scale on the surface of filtration media to cause blockage, and also influence the normal operation of dust-removal equipment. Water-proof& Oil-proof Acupuncture Felt can effectively prevent the attachment of infiltration of water and different kinds of oil filth. Compared with ordinary filtration media, it possesses the quality of oil-proof, as well as adhesion resistance and easy separation.
