Described shifting board is dislocation pull removable jew.
Described disturbance layer shifting board is located at both sides, space outside surface and is positioned on disturbance layer active clapboard.
Described fan is two groups, shifts to install on two sides, upper space.
The beneficial effects of the utility model:
(1) provide a closed system at different external condition Imitating air nature dry deposition, environment does not have any impact to external world simultaneously.
(2) design the disturbance layer of an air borne dust first, 4 built-in strong electric fans have been installed, by aerodynamic force condition, sufficient disturbance have been carried out to SEDIMENTATION FOR FINE PARTICLE thing.
(3) in practical application, except consuming small part electric power, substantially only complete whole depositing dust process by Action of Gravity Field, economical environment-protective, structure are simple, cost is low and easily operate, can the dry deposition process of simulated atmosphere effectively.Thus provide technical support in Soil-Vegetable System from the biological effectiveness of the heavy metal of dry deposition and variation characteristic thereof.
