根据生产工艺、设备布置、排风量大小和生产厂房条件,除尘器系统分为就地除尘、分散除尘和集中除尘三种形式。
According to the production process, equipment layout, exhaust volume and production plant conditions, the dust collector system can be divided into three forms: local dust removal, decentralized dust removal and centralized dust removal.
集中除尘系统
Centralized dust removal system
集中除尘系统适用于扬尘点比较集中,有条件采用大型除尘设备的车间。它可以把排风点全部集中于一个除尘系统,或者把几个除尘系统的除尘设备集中布置在一起。由于除尘设备集中维护管理,回收粉尘容易实现机械化处理。但是,这种系统管道长、复杂,压力平衡困难,初投资大,因此这种系统仅适用于少数大型工厂。
The centralized dust removal system is suitable for the workshop where the dust points are relatively concentrated and large dust removal equipment is available. It can concentrate all the exhaust points in one dedusting system, or arrange the dedusting equipment of several dedusting systems together. Due to centralized maintenance and management of dust removal equipment, it is easy to realize mechanized treatment of recovered dust. However, this kind of system is long, complex, difficult to balance the pressure and large initial investment, so it is only suitable for a few large factories.
分散除尘系统
Decentralized dust removal system
车间除尘设备
当车间内排风点比较分散时,可对各排风点进行适当的组合,根据输送气体的性质及工作班次,把几个排风点合成一个系统。分散式除尘系统的除尘器和风机应尽量靠近产尘设备。这种系统风管较短,布置简单,系统压力容易平衡。由于除尘器分散布置,除尘器回收粉尘的处理较为麻烦。这种系统目前应用较多。
When the exhaust points in the workshop are relatively scattered, the exhaust points can be properly combined, and several exhaust points can be combined into a system according to the nature of the delivered gas and the work shift. The dust collector and fan of the distributed dust removal system should be close to the dust producing equipment as far as possible. This system has short air duct, simple layout and easy system pressure balance. Due to the scattered arrangement of dust collectors, the treatment of dust recovered by dust collectors is more troublesome. This system is widely used at present.
就地除尘
Local dust removal
它是把除尘器直接安放在生产设备附近,就地捕集和回收粉尘,基本上不需敷设或只设较短的除尘管道。如铸造车间混砂机的插入式袋式除尘器、直接坐落在风送料仓上的除尘机组和目前应用较多的各种小型除尘机组。这种系统布置紧凑、简单、维护管理方便。
The dust collector is directly placed near the production equipment to collect and recover the dust on the spot. Basically, there is no need to lay or set a short dust removal pipeline. For example, the plug-in bag filter of sand mixer in foundry workshop, the dust removal unit directly located on the air feed bin and various small dust removal units which are widely used at present. This system is compact, simple and easy to maintain.
