Activated carbon filter for components of nitrogen generating unit

Activated carbon filter, pressure vessel, pressure vessel is filled with coarse sand and high quality activated carbon.

Function: In the water treatment system, the activated carbon filter can absorb the residual chlorine is unable to get rid of the pre-filter on its degradation to prevent secondary reverse osmosis membrane, the adsorption of small organic molecules also leaks the pre-stage and other polluting substances, the role of the water is more obvious adsorption removal, colloidal odor and pigment, heavy metal ions, but also has the effect of reducing COD. In order to further reduce the inlet SDI value RO, SDI < 5, TOC < 2.oppm.

The activated carbon filter works through the carbon bed. Carbon is. The activated carbon particles composed of the carbon bed have a large number of pores and specific surface areas, and have strong adsorption capacity. Water through the carbon bed, the use of activated carbon adsorption water organic pollutants effectively. In addition, the amorphous part of the surface of the activated carbon, the organic pollutants containing oxygen functional groups, are effectively absorbed by the carbon bed water with activated carbon. Activated carbon filter is a more commonly used water treatment equipment, seawater desalination system as a pretreatment can effectively ensure the service life of the equipment, improve the quality of water, pollution prevention, especially to prevent post-stage reverse osmosis membrane, free oxygen ion exchange resin and other toxic substances pollution.

The main factors affecting the adsorption and service life of activated carbon filtration are: the type and concentration of air pollutants, the filter material at the residence time, the temperature and humidity of the air.

In actual use, according to the type of pollutants, concentration and flow conditions, determine the form of filter and activated carbon species.

The activated carbon filter pressure swing adsorption nitrogen machine in the assembly after the purification system, the nitrogen device, the main role is to be treated by the cold dryer, Wanda precision filter out the compressed air in the oil, water and other substances, in addition to deodorization, acid removal, etc., so the compressed air into the nitrogen machine in a small purification. In general, the activated carbon filter will be replaced in 4,000 hours of use, (about half a year), otherwise the oil removal is not net, which can poison the carbon molecular sieve, thus affecting the purity of nitrogen.

There should be a good dust collector downstream of the activated carbon filter, and its efficiency and specifications should not be less than F7. In order to prevent dust clogging the upstream and downstream filters of activated carbon materials; Dust filter activated carbon itself stops.
