Description

一种工业滤袋除尘器
技术领域
本发明属于滤袋除尘领域，具体一种工业滤袋除尘器。
背景技术
袋式除尘器在工业生产中广泛使用，由于其结构简单易于维护，在实际使用过程中得到了广泛的好评。现有的袋式除尘器大都由滤袋框和除尘袋的组合构成，并且，现有的袋式空气过滤器只采用一层滤袋过滤的方式，其过滤效果有限，不能够高效完成灰尘较多、颗粒较大的空气过滤作业，且在过滤灰尘较多、颗粒较大的气流时，除尘袋很容易发生堵塞，导致除尘袋的除尘周期有限，除尘袋上沉积的灰尘不易去除干净。同时除尘袋在过滤过程中由于其本身机械性能有限，导致了过滤高强气流中的灰尘时，除尘袋在长期使用过程中，尤其是在高温条件下长期使用过程中，除尘袋的寿命有限，过滤性能逐步下降。
发明内容
本发明的目的在于提供一种工业滤袋除尘器，通过静电除尘结合后期的布袋除尘最大限度地去除尘粒，同时通过浸碳除尘网的改性，实现除尘与浸碳效果的同时提升。
本发明通过以下技术方案实现：
本发明提供了一种工业滤袋除尘器，包括除尘器的本体，本体的一端设置入口，另一端设置除尘袋，本体内部设置浸碳除尘网，其中浸碳除尘网两端设置导线接头，浸碳除尘网与入口之间的本体内部设置有电晕线。
进一步地，所述的工业滤袋除尘器，本体上设置有插槽，浸碳除尘网以可拆卸的方式插入插槽。
进一步地，所述的工业滤袋除尘器，除尘袋与本体以可拆卸方式连接。
进一步地，所述的工业滤袋除尘器，浸碳除尘网与入口之间的本体底部设置储尘仓，储尘仓上设置有仓门。
进一步地，所述的工业滤袋除尘器，浸碳除尘网由以下重量份计的组分制备而成：环氧树脂6-8份，聚二甲基硅氧烷3-8份，聚氧乙烯脂肪酸酯1-3份，碳粉15-20份，二异氰酸酯4-8份，2,6-二叔丁基对甲酚0.5-1份，酚醛树脂4-7份，苯乙烯2-5份，丙纶纱线20-30份，聚醚二元醇2-5份和溶剂300-350份。
更进一步地，环氧树脂可为双酚A型环氧树脂；溶剂可为甲苯、正丁醇或异丁醇。
更进一步地，浸碳除尘网的制备方法如下：
步骤1，将环氧树脂粉碎至粒径200μm以下，得到环氧树脂粉末；
步骤2，将环氧树脂粉末与丙纶纱线混合，得纱线混合物，再在表面涂刷聚醚二元醇和聚二甲基硅氧烷的混合物，然后热压成型；
步骤3，将碳粉分散于溶剂中，加入聚氧乙烯脂肪酸酯，混合后在氮气保护条件下加入二异氰酸酯，2,6-二叔丁基对甲酚，酚醛树脂和苯乙烯，混合后得到浸碳混合液；
步骤4，将步骤2热压成型后的纱线浸入步骤3得到的浸碳混合液中，35-40℃下反应130-150分钟，然后再在60-70℃条件下反应250-280分钟，降至室温，取出纱线，烘干，得到浸碳纱线；
步骤5，将浸碳纱线进行织网，得到浸碳除尘网。
更进一步地，步骤4中烘干的温度可为80-100℃。
本发明提供的工业滤袋除尘器利用浸碳除尘网作为电极和除尘载体，能够最大限度地发挥除尘效果，不仅通过静电除尘能够吸附尘粒，同时作为除尘网自身也能够发挥除尘作用，进而提高了除尘效果。
本发明提供的静电除尘能够有效的进行前期的尘粒的过滤和去除，很好的避免了后期除尘袋除尘过程中由于大量尘粒造成的堵塞。
本发明还提供了浸碳除尘网及其制备方法，该浸碳除尘网具有良好的综合性能，不仅增强了滤网的机械性能，同时经涂覆后的滤网表面水滴角达到了126°以上，同时显著提升了滤网的拉伸断裂强度。滤网上的灰尘能够较为容易的被清除，延长了滤网使用寿命。
本发明提供的浸碳除尘网，通过将丙纶纱线进行改性，使得其更加容易与后期浸碳混合液中的组分共聚来提高碳粉与纱线的结合力。丙纶纱线混合改性后，在后期浸碳过程中，浸碳混合液中的二异氰酸酯，2,6-二叔丁基对甲酚，酚醛树脂和苯乙烯在共聚改性的过程中，通过低温(35-40℃)改性嫁接与高温(60-70℃)共聚反应，能够与改性后的丙纶纱线共聚结合，从而牢固地将碳附着在纱线表面，形成复合共聚体，显著增强了纱线的机械性能，同时在表面形成聚合表面的防水膜层，增强了灰尘的易去除性。
本发明通过将丙纶纱线的改性浸碳，巧妙地实现了静电除尘与滤网特性的双重提升，将以上特性通过特定组分与制备方式的结合协同实现。
