Gas Flow-Field Numerical Simulation And Capture Effect Research Of Up-suction Hood

Most of China's shoe-making industry to manual brushing adhesive production, the production process widely used solvent-based adhesives, adhesive in these solvents if not taken effective measures, the health workers will cause great harm.In order to reduce the harm, shoe-making industry has been using low toxicity, non-toxic adhesive solve the problem of toxic hazards, but at the end of the bond to help connect parts, in order to ensure cohesive and adhesive bonding product quality production process requirements, not still need to avoid the use of the solvent-containing adhesive. To improve the air quality of hand-brushing workplaces, occupational health standards meet the requirements of the ventilation detoxification measures must be taken. According to manual brushing workplaces adhesive characteristics of the work, select external exhaust hood (suction hood) control. On the use of suction hood trap control, it should also be considered that the shoe-making workshop gooey-brushing workplace space layout, production process conditions and human relations, and so on, initially determined the location and shell size, be taken airflow numerical simulation and physical model of combining the re-testing methods, in order to maximize production in line with the actual operating conditions to identify external enclosures physical parameters and trapping efficiency of the relationship between the selection of reasonable parameters. In this paper, through the establishment of FLUENT computational fluid dynamics software model, under cover internal airflow velocity vector flow, air flow field of organizational forms, has been selected for the exhaust hood shell specifications, covering population size, shell form.In this paper, the experimental identified suitable footwear adhesives hand brushing the exhaust hood workplace forms for different Shuajiao area I find the mask size, height, baffle, ventilation conditions of the five parameters on the effect of control , obtained under different conditions on the suction hood breathing with the fixed point of collection efficiency measured the changes in the law.This paper concluded manual brushing adhesive workplace exhaust hood selection of the design provides a useful basis of data for similar workplace ventilation control with detoxification learn.
