Taking an aluminum tank semitrailer as an example, this essay aim to analyze the strength and stiffness of the tank semitrailer and obtain stress and strain characteristics under different conditions on the basis of a finite element model, by using the finite element analysis software. By carrying on modal analysis in different work conditions, the essay gets the dynamic performance parameters of the tank. The results show that the tank fully meets the requirements of using, and the performance parameters of the tank will be foundation for the optimization.

Simultaneous desulfurization and denitrification removes SO2 and NOx from flue gas in one unit and only uses one absorbent. Using urea as absorbent removing SO2 and NOx in semi-dry spouted bed has the enormous developmental potential and wide foreground for it overcomes two shortages of wet process such as the amount of urea is large and the waste water is difficult to handle. The chemical absorption mechanism and thermodynamics of SO2 and NOx with urea were studied, the operating condition optimization of spouted bed was determined through several repeating experiment, the effects of some important operational parameters such as molar ratio of urea and gaseous pollutant, inlet temperature of flue gas and approach to adiabatic saturation temperature on SO2 and NOx removal efficiency were analyzed. The results provide a foundation for the commercial scale application of simultaneous desulfurization and denitrification technology.

In this paper the desulfurization and denitration of simulation flue gas using calcium hypochlorite as absorbent was studied experimentally. Absorption experiments of the desulfurization and denitration in calcium hypochlorite solutions were carried out in a Porous Globular Gas Liquid Reactor (PGGLR) which was a new and innovative core design. Three experiments were conducted at NTP conditions. The mechanism of removal for SO2 and NOX was investigated. Under these experiment conditions, the removal efficiency of 100%, 67% for SO2 and NOX were achieved. The results can offer valuable references for industrial application.

Spouted bed with porous draft tube is an improved type of conventional spouted bed which is a special kind of fluidized bed. Hydrodynamic characteristics are vital to design and normal operating of spouted bed with porous draft tube, but less research has been carried out. Two key hydrodynamics factors including maximum spouted bed height and minimum spouting velocity were studied by a series of experiments. The effects and mechanisms of features of draft tube including diameter, installing position and hole opening ratio on hydrodynamics factors were analyzed. The results are of great value to the design and optimization of spouted bed with porous draft tube and broad the engineering application sphere of spouted bed.

In order to improve the quality of semi-trailer tanker design, shorter the development cycle, lower cost, and combine with structural features of its own semi-trailer tanker, the use of modular design theory, a module partition, structural analysis and interface settings and other methods of semi- trailer to the overall structure of tanker design the general framework of semi-trailer tanker. With the UG/OPEN and Microsoft C++6.0 development tools, parameterize the parts of semi-trailer tanker. Developed in the context of the semi-trailer tanker UG rapid design system design module, and verify its feasibility.
