产品详细介绍
除尘布袋可以说是除尘器的心脏而滤袋的选用则至关重要,因为它直接影响除尘器的除尘效果。
拒水防油布袋可有效防止水及各种油污物沾附和渗透和普通滤袋相比,不仅具有防水防没特性而且对粉尘而言还具有抗粘结性和易剥离性。通常在使用高原式电磁脉冲阀除尘器时,必须对除尘器滤袋做好选择,一台除尘器是否能够正常的工作,除尘布袋的作用是必不可少的,所以我们也要对除尘滤袋做出好选择,最好是选择优质的滤袋。
我们在选择时,应当注意,滤布必须有合适的孔隙,允许空气顺利通过而阻挡细小的粉尘进入滤布内部。细小颗粒的粉尘一旦进入滤布内部,就无法将其清除,造成滤布透气性能大大下降,除尘阻力增大,甚至滤袋无法再使用。这也是为什么除尘器滤袋纤维直径要求较细、滤布较“密实”的原因。
总之,在选择滤袋材料时,最好参考相关资料或请教专业生产厂和专家。现在滤袋生产厂很多,品种差异大.价格差异也大。在选择滤袋时要综合考虑价格、使用寿命和处理物料的物性。特别是外购除尘器时不能单纯考虑价格。还必须考虑其配置和材料。有的滤袋处理某种粉尘有效,但对其他粉尘可能不是最佳。滤布结构可以是毡制的或编织的。大多数毡制品由于纤维间的毛细作用会吸潮但一些特殊的毡制品比如玻璃纤维针织毡可以在一定程度上防潮。毡制品纤维的不规则排列,孔隙均匀,同时为了保证其强度,滤袋厚度较厚,除尘效率高。 在一些重要场合或粉尘细的物料,特别是具有较高表面气流速度的除尘器滤袋经常采用。编织的纤维织品是用纺纱编织而成的。纺纱间有各种花纹的孔隙,表面光洁,容易设计成可以保持或脱离滤饼的滤布。为了进一步提高表面性能,可以用硅酮树脂喷涂,获得耐磨表面、改进滤饼的脱离或降低滤袋的吸潮能力。对熔点低、粘附性大的各种化学药品最好采用编织纤维的滤袋。In short, when the in select filter bag material, it is best to refer to the relevant information, or consult a professional production factory and experts. The filter bag plant a lot of species differences. Price difference. The choice of filter bag and comprehensive consideration of the physical properties of price, service life and processing materials. Especially outsourcing precipitator, can not simply consider the price. Configuration and materials must also be considered. Some some sort of dust filter bag processing, but other dust may not be the best. Filter cloth structure can be felted or woven. Most carpet products due to the capillary action between the fibers will absorb moisture but some special carpet products such as a glass fiber knitted mat can to a certain extent on the moisture. Felts fibers irregularly arranged, uniform porosity, in order to ensure its strength at the same time, the bag is thicker, high dust removal efficiency. In some important occasions fine material or dust, particularly those having high surface air velocity precipitator bag often used. The woven fiber fabric is woven with spinning. Spinning between various patterns of pores, smooth surface, easy to design a filter cloth can be kept out of cake. In order to further improve the surface properties can be sprayed with a silicone resin, the wear surface, to improve the detachment of the filter cake, or reduce moisture absorption capacity of the bag. Preferably, the adhesion to a large variety of chemicals using the low melting point, the woven fiber filter bag.
