Discharged after discharge or burning disposal.Adhesion or higher organic of low-resistance absorption material absorption boiling point for accommodating Hydrophobic adsorptive resin
After heavy constituent, steam regeneration effect is bad, can be regenerated by appropriate organic solvent, first dissolves heavy constituent and washes out, then uses
Steam blows out organic solvent, recovers organic heavies ability, including absorption precision and capacity.
The adhesion or the low-resistance absorption material for accommodating Hydrophobic adsorptive resin, during for gas treatment, adhere to or accommodate
The absorption property of Hydrophobic adsorptive resin influenceed smaller by gas humidity, bed does not have temperature rise, adsorbance and absorption substantially
Stable accuracy, is substantially not present the degraded of adsorption component, and the organic material of recovery is substantially free of degradable component, repeatedly the suction after regeneration
Attached capacity, absorption precise decreasing are smaller, and service life is longer, thus can obtain wide application.
In practical application, except using single specification the utility model low-resistance adsorb material, can also use including one kind with
Upper resinous type and/or absorption material shape, the composite bed of size, by the different shape based on same resin microsphere and/or
The low-resistance absorption material layering filling of size, or by identical or different shape and/or size based on variety classes resin microsphere
Low-resistance absorption material layering or mixed packing, can also gas or liquid outlet section directly using adsorb or ion exchange resin it is micro-
Ball bed, to obtain bed pressure drop, reclaiming clean removal effect and the balance between the regeneration period.
Now conventional granular, bar shaped activated carbon or NACF, it is de- for the organic matter adsorption cleaning processing in gas
Except when, absorption property is influenceed larger by gas humidity, and bed temperature rise is obvious or larger, adsorbance and absorption precision it is wet by gas
The influence of degree and bed temperature is larger, and adsorbate degraded is also resulted in sometimes, the organic material of recovery is contained more degradable component, many
Substantially, service life is shorter, thus application is limited or effect is not ideal enough for adsorption capacity, absorption precise decreasing after secondary regeneration,
Or operating cost is higher；For during the adsorption cleaning processing of organic matter, adsorption capacity repeatedly after regeneration, absorption to be smart in liquid
Degree declines comparatively fast, and service life is shorter.
