Description

一种风机滤器单元和无尘室空气净化系统
【技术领域】
本发明涉及电子产品制造领域, 更具体的说, 涉及一种风机滤器单元和无 尘室空气净化系统。
【背景技术】
很多电子产品为了避免粉尘颗粒影响产品品质, 一般会建立无尘室来过滤 空气中的粉尘等固体颗粒杂质。 参见图 1 无尘室在建筑顶端铺设有风机滤器单 元( Fan Filter Units ,以下筒称 FFU ) ,也就是将风机和过滤器(高效过滤器( ΗΕΡΑ ) 或超高效过滤器(ULPA ) )组合在一起构成自身提供动力的末端净化设备。 风 机从 FFU顶部将空气吸入并经 ΗΕΡΑ过滤, 过滤后的洁净空气在整个出风面以 0.45m/s ± 20%的风速均匀送出。 FFU将空气中的微粒过滤后, 将大微粒封锁在 FFU内部,输出洁净的空气。 大多 FFU由于被粉尘堵塞过滤器而报废无法使用, 因此常常达不到额定的使用寿命。
【发明内容】
本发明所要解决的技术问题是提供一种可延长使用寿命的风机滤器单元和 无尘室空气净化系统。
本发明的目的是通过以下技术方案来实现的:
一种风机滤器单元, 包括风机、 与风机入风口耦合的滤网, 所述滤网的入 风口还设有辅助过滤网, 所述辅助过滤网可过滤的粉尘的最小直径大于所述滤 网可过滤的粉尘的最小直径。
进一步的, 所述辅助过滤网通过螺丝固定或卡扣固定的方式固定在所述风 机滤器单元的入风口。 辅助过滤网需要过滤颗粒较大的粉尘, 因此会很容易积 攒灰尘, 需要经常清理。 做成可拆卸, 可以需要清理的时候拆卸下来, 既方面 清理, 还可以在拆卸后直接更换一个清理好的辅助过滤网, 这样设备也无需停 机, 不影响生产。
一种无尘室空气净化系统, 包括生产层, 以及与生产层连接的风机滤器单 元, 所述风机滤器单元包括风机、 与风机入风口耦合的滤网, 所述滤网的入风 口还设有辅助过滤网, 所述辅助过滤网可过滤的粉尘的最小直径大于所述滤网 可过滤的粉尘的最小直径。
进一步的, 所述滤网和辅助过滤网之间还设有空气冷凝层。 冷凝后的空气 有助于粉尘的积淀、 分离。
进一步的, 所述辅助过滤网通过螺丝固定或卡扣固定的方式固定在所述空 气冷凝层上。 辅助过滤网需要过滤颗粒较大的粉尘, 因此会很容易积攒灰尘, 需要经常清理。 做成可拆卸, 可以需要清理的时候拆卸下来, 既方面清理, 还 可以在拆卸后直接更换一个清理好的辅助过滤网, 这样设备也无需停机, 不影 响生产。
进一步的, 所述空气冷凝层和滤网之间还设有空气回流过滤层。 空气回流 过滤层一方面给各个风机滤器单元供气, 自身也具备一定的粉尘过滤功能。
进一步的, 所述生产层的出风口和所述风机滤器单元之间还设有温控通风 层, 所述辅助过滤网设置在所述温控通风层内。 辅助过滤层位于宽敞的控温通 风层, 更换的时候只需要站在地板上直接更换即可, 非常方便。
进一步的, 所述温控通风层和空气回流过滤层之间还设有回风道, 所述温 控通风层和空气回流过滤层的气流通过回风道相通。 此为一种具体的无尘室空 气净化系统。
进一步的, 所述风机滤器单元的出风口连接到所述生产层的顶部, 其入风 口连接到生产层的底部。 粉尘质量大于空气, 因此会往生产层的底部沉积, 因 此气流生产层底部抽离, 可以将沉积到底部的粉尘抽离, 从生产层抽离的气流 进入风机滤器单元, 经过风机滤器单元过滤后从生产层的顶部吹出, 吹出的气 流可以让悬浮的粉尘加速运动到生产层底部, 从底部抽离, 如此循环往复, 使 生产层保持无尘状态。 进一步的, 所述风机滤器单元的出风口连接到所述生产层的顶部, 其入风 口连接到生产层的底部; 所述生产层的出风口和所述风机滤器单元之间还设有 温控通风层, 所述辅助过滤网设置在所述温控通风层内; 从所述辅助过滤网到 滤网之间依次设有空气冷凝层和空气回流过滤层, 所述辅助过滤网通过螺丝固 定或卡扣固定的方式固定在所述空气冷凝层上; 所述温控通风层和空气回流过 滤层之间还设有回风道, 所述温控通风层和空气回流过滤层的气流通过回风道 相通; 所述辅助过滤网可拆卸。 此为一种具体的无尘室空气净化系统。
发明人研究发现, 粉尘颗粒进入各通风管道, 滤网中, 大的颗粒会先沉积 下来, 然后小的颗粒会粘附在大颗粒表面, 这样灰尘层层堆积, 很快就会堵塞 管道和滤网, 缩短了风机滤器单元和无尘室空气净化系统的使用寿命。 本发明 增加了辅助过滤网, 先将大的粉尘颗粒过滤, 一方面减少了进入到各管道及滤 网的粉尘, 另一方面进入的粉尘颗粒较小, 不容易沉积, 保持了整个风道的畅 通, 使用时只需要定期更换辅助过滤网即可。 这样采用双重过滤, 大小颗粒分 工过滤, 提高过滤效率, 提高 FFU使用寿命, 降低过滤系统更换频率及难度, 降低 FFU耗材成本, 进而提高了整个无尘室空气净化系统的使用寿命。
【附图说明】
图 1是现有的无尘室空气净化系统的示意图;
图 2是本发明实施例的无尘室空气净化系统的示意图。
【具体实施方式】
本发明公开了一种无尘室空气净化系统。 该无尘室空气净化系统包括生产 层, 以及与生产层连接的风机滤器单元, 所述风机滤器单元包括风机、 与风机 入风口耦合的滤网, 所述滤网的入风口还设有辅助过滤网, 所述辅助过滤网可 过滤的粉尘的最小直径大于所述滤网可过滤的粉尘的最小直径。
发明人研究发现, 粉尘颗粒进入各通风管道, 滤网中, 大的颗粒会先沉积 下来, 然后小的颗粒会粘附在大颗粒表面, 这样灰尘层层堆积, 很快就会堵塞 管道和滤网, 缩短了风机滤器单元和无尘室空气净化系统的使用寿命。 本发明 增加了辅助过滤网, 先将大的粉尘颗粒过滤, 一方面减少了进入到各管道及滤 网的粉尘, 另一方面进入的粉尘颗粒较小, 不容易沉积, 保持了整个风道的畅 通, 使用时只需要定期更换辅助过滤网即可。 这样采用双重过滤, 大小颗粒分 工过滤, 提高过滤效率, 提高 FFU使用寿命, 降低过滤系统更换频率及难度, 降低 FFU耗材成本, 进而提高了整个无尘室空气净化系统的使用寿命。
参见图 2, 无尘室空气净化系统的中心是生产层, 生产层内部工事最多, 人 员进出最频繁, 各种设备也在这一层运行, 是无尘室粉尘的主要来源。 风机滤 器单元 (FFU)的出风口连接到所述生产层的顶部, 其入风口连接到生产层的底 部。 粉尘质量大于空气, 因此会往生产层的底部沉积, 因此气流生产层底部抽 离, 可以将沉积到底部的粉尘抽离, 从生产层抽离的气流进入风机滤器单元, 经过风机滤器单元过滤后从生产层的顶部吹出, 吹出的气流可以让悬浮的粉尘 加速运动到生产层底部, 从底部抽离, 如此循环往复, 使生产层保持无尘状态。
生产层的出风口和所述风机滤器单元之间还设有温控通风层, 辅助过滤网 固定在温控通风层; 从辅助过滤网到滤网之间, 依次设有空气冷凝层和空气回 流过滤层。 冷凝后的空气有助于粉尘的积淀、 分离; 空气回流过滤层一方面给 各个风机滤器单元供气, 自身也具备一定的粉尘过滤功能。
温控通风层和空气回流过滤层之间还设有回风道, 温控通风层和空气回流 过滤层的气流通过回风道相通。
辅助过滤网设置在所述温控通风层内, 并通过螺丝固定、 卡扣固定等可拆 卸的方式固定在空气冷凝层上。 辅助过滤网需要过滤颗粒较大的粉尘, 因此会 很容易积攒灰尘, 需要经常清理。 做成可拆卸, 可以需要清理的时候拆卸下来, 既方面清理, 还可以在拆卸后直接更换一个清理好的辅助过滤网, 这样设备也 无需停机, 不影响生产。 而控温通风层邻近生产层, 更换辅助过滤网的时候只 需要站在地板上直接更换即可, 非常方便。 以上内容是结合具体的优选实施方式对本发明所作的进一步详细说明, 不 能认定本发明的具体实施只局限于这些说明。 对于本发明所属技术领域的普通 技术人员来说, 在不脱离本发明构思的前提下, 还可以做出若干筒单推演或替 换, 都应当视为属于本发明的保护范围。
