explosion protection for vehicles intended for the transport of Flammable Gases and liquids
Journal of Hazardous Materials, 2009Co-Authors: Hans Forster, Werner GuntherAbstract:In Europe, the transport of Flammable Gases and liquids in tanks has been impacted by new developments: for example, the introduction of the vapour-balancing technique on a broad scale and the steady increase in the application of electronic components with their own power sources; furthermore, new regulatory policies like the ATEX Directives are being enforced in the European Union. With this background in mind, the present investigation aims to provide a basis for future developments of the relevant explosion protection regulations in the safety codes for the transport of dangerous goods (RID/ADR). Specifically, the concentration of gas in the air was measured under various practical conditions while tank vehicles were being loaded with Flammable Gases or liquids. These spot-test data were supplemented by systematic investigations at a road tanker placed in our test field. With respect to non-electrical ignition sources, a closer investigation of the effect of hot surfaces was carried out. With regard to improving the current regulations, the results of our investigation show that it would be reasonable to implement a stronger differentiation of the characteristics of the dangerous goods (gaseous/liquid, flashpoint) on the one hand and of the techniques applied (loading with and without vapour-balancing system) on the other hand. Conclusions for the further development of the current international regulations are proposed.

research on the detection of mixed Flammable Gases using a single catalytic sensor based on rbf neural network
Chinese Journal of Sensors and Actuators, 2009Co-Authors: Tong MinmingAbstract:Based on the sensitivity of catalytic sensor is different in different temperatures,a new method of analyzing Flammable Gases with a single catalytic sensor based on thermostatic detection and RBF neural network theory was put forward.A mathematic model of analyzing the diversiform inFlammable Gases was erected by RBF neural network of dynamic learning algorithm.By the experiment of mixed Gases such as firedamp,carbon monoxide and hydrogen,the result showed the possibility to analyze mixed inFlammable Gases by one catalytic sensor.

research of detecting mixed Flammable Gases with a single catalytic sensor based on rbf neural network
International Conference on Intelligent Computing, 2011Co-Authors: Yu ZhangAbstract:Utilizing the variation in the detection sensitivity of the catalytic sensor under different temperatures, a new method of analyzing inFlammable Gases with a single catalytic sensor based on thermostatic detection and RBF neural network theory is proposed. A mathematical model of analyzing different inFlammable Gases is constructed based on dynamic learning algorithm. Experiments were carried out with sample mixed Gases of firedamp, carbon monoxide and hydrogen. The results show that the mixed inFlammable Gases can be effectively analyzed by the single catalytic sensor.

facile synthesis of zno nanorod arrays and hierarchical nanostructures for photocatalysis and gas sensor applications
Journal of Hazardous Materials, 2011Co-Authors: Rong Li, Changpeng Lv, Wei XuAbstract:Abstract A facile one-step hydrothermal route was demonstrated to grow ZnO nanorod arrays and hierarchical nanostructures on arbitrary substrates without any catalysts and seeds coated before the reaction, which are prerequisite in the current two-step protocol. Meanwhile, ZnO nanoflowers composed of nanorods were obtained at the bottom of the autoclaves in the absence of substrates. An in situ spontaneous-seeds-assisted growth mechanism was tentatively proposed on the basis of the experimental data to explain the growth process of ZnO nanostructures. Moreover, the obtained ZnO nanorod arrays exhibited superior photocatalytic activity for decomposing methyl orange, and the nanoflowers showed better gas sensing performance towards some Flammable Gases and corrosive vapors with high sensitivity, rapid response–recovery characteristics, good selectivity and long-term stability.
