Front flow guiding plate-this guide plate is that upper and lower two edges of boards are fixed on the device case front portion up and down on the inwall, leaves the vertical panel in gap with device case;
Back guide plate-this back guide plate be positioned at the device case mid-rear portion, be positioned at two vertical panels on the same cross section; Its upper and lower both sides are separately fixed at device case up and down on the inwall; Side is fixed on the device case sidewall, and leaves clearance channel between the guide plate after two;
Chemical filtering layer-this filter layer is two groups, is symmetricly set between front flow guiding plate and back guide plate along the device case axial direction, is made up of the chemical filtering medium that filters sieve plate and be filled between sieve plate;
Rearmounted filter plate-this postposition filter plate is arranged at the device case afterbody, and its limit portion is fixed on the device case inwall.
The air filter of a kind of air compressor of the utility model, the filtration sieve plate that it is characterized in that its chemical filtering layer are three and form two filling spaces that the filter medium of SOx, NOx is filtered in one of them filling space filling, another filling filtration Cl
2And the filtering agent of other gaseous acid contact scar thing.
The air filter of a kind of air compressor of the utility model is characterized in that its rearmounted filter plate is three layers, and the gap is provided with, and is respectively rearmounted primarily efficient filter plate, rearmounted medium air filtration plate and rearmounted high efficiency filter plate.
The air filter of a kind of air compressor of the utility model; Special in airborne sour gas; Mode through the two-stage chemisorption cleans air; First order chemical filtering is used to remove airborne big dust particle and SOx, NOx, and second level chemical filter is used to remove airborne Cl
2And other gaseous acid contact scar thing.When the corresponding sorbent, gaseous contaminant at first is adsorbed in the sorbent at air, carries out chemical reaction with wherein active substance, converts metastable material to, thereby reaches the purpose that purifies air.Filter filtering scheme flow process is:
The air filter of a kind of air compressor of the utility model can effectively be removed airborne solid particulate matter and sour gas, installs simply, and is easy to maintenance, can realize the on-bne repair of filter.
