本实用新型公开了一种工业废气治理用活性炭吸附装置,涉及废气治理技术领域,包括过滤筒,所述过滤筒内固定安装有倾斜设置的过滤网,所述过滤筒上转动安装有螺杆,所述螺杆上螺纹套接有刮板,所述刮板靠近过滤网的一端设置有刷毛,所述过滤筒的底端开设有通孔,所述通孔内插设有收集盒,所述收集盒的底端固定连接有底板,所述底板上滑动插设有与过滤筒相插接的插接件,所述底板的截面呈"凹"形.本实用新型通过在过滤筒外侧转动螺杆,以使得螺杆驱动刮板移动,从而在过滤筒外侧即可对过滤网上吸附堵住的杂质进行清理,同时通过过滤网的倾斜设置,使得过滤网上掉落下来的杂质得以被收集盒接住从而方便处理.

铜基改性活性炭吸附净化工业废气中的气态噻吩

Cu-based modified activated carbon prepared by impregnation was used for adsorbents of CHS purification. The active component, oxygen concentration, adsorption temperature, component were investigated for CHS adsorption adsorptive purification. The effects of preparation conditions on the adsorbent were characterized by Nadsorption-desorption (N-BET), scanning electron microscope (SEM), energy dispersive spectrometer (EDS), X-ray photoelectron spectroscopy (XPS) and X-ray diffraction (XRD). The results show that the optimal condition for adsorptive purification are Cuconcentration of 0.1 mol/L, cremation temperature of 300 ℃ and adsorption temperature of 20 ℃, oxygen mass fraction of 1%. The adsorption efficiency can reach 90% within 400 min. The Cu-based modified activated carbon has a higher specific surface area and also the adsorption capacity has greatly improved compared with the pristine sample. Furthermore, it can effectively prevent the active component from sintering during the adsorption process, with CuO as the effective component for purification of CHS.
