Embodiment Construction
[0028] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0029] see figure 1 , figure 2 , image 3 with Figure 4 , Schematic diagram of the experimental device for the study of flow field and pollutant diffusion in urban continuous canyon streets. Field tracer mechanism, street valley floor heating mechanism and multi-parameter measurement mechanism;
[0030] see figure 1 , the wind tunnel mechanism includes a simple tunnel structure 5 and a longitudinal ventilation device, the simple tunnel structure 5 has a height of 1.8-2.2 meters, a width of 1.5-2 meters, and a length of 15-20 meters. The longitudinal ventilation device is composed of more than two frequency conversion fans 6 and more than two diversion air ducts 7, forming a honeycomb structure to provide stable ambient wind for continuous canyon streets; the wind tunnel mechanism generates urban wind through more than two frequency conversion fan...
