Self-cleaning mechanical filter for potentially explosive atmospheres
Dustdown® ATEX is a very high efficiency self-cleaning mechanical filter, equipped with an automatic on-line cleaning system with a Reverse Jet of compressed air. Dustdown® was designed by Tecnosida® to address the specific problems associated with treating emissions potentially explosive that are subject to the 2014/34/EU directive.
The air to be treated enters the lower part of the dust remover, passes through a pre-filtering chamber that allows the coarse dust to precipitate, protecting the filter from excessive dust loads.
The flow then reaches the filtering surface and passes through it with consequent realization of the separation of the particulate. The dust collected by the numerous sleeves precipitates to the bottom of the filter where the hoppers direct it to the collection system (cochlea, rotary star valve, clapet valve or screw with conduit/pipe) or automatic discharge. In this case, the hopper must be more angular than the friction angle of the recovered pollutant, in order to avoid deposits of material.
The filtering surface is made of sleeves of various antistatic materials suitable for use in potentially explosive areas. It is kept in perfect condition thanks to automatic cleaning cycles managed on the basis of the filter pressure loss readings to limit the compressed air consumption and increase the lifetime of the sleeves.
DUSTdown® ATEX is equipped with a sealing structure made of reinforced material able to withstand high pressure resulting from possible explosions. The junction flanges are also equipped with jumpers which guarantee equal-potential continuity.
Depending on the classification of the application area, the filter is equipped with various components specially sized for use in potentially explosive atmospheres.
The main components of the ATEX filter are:
