Hps Clarifier Structure Finite Element Analysis

" A new clarifier " as a type of New raw water purification technology, By compressing process on a conventional clarifier, expanding the scope of water turbidity, improving design structure at the end of the pool, to meet Designed treated water requirements. Compared to conventional water purification process, it has a advantages of strong anti-shock capacity, low cost of investment、eration and maintenance, small area of Covering. Combined with the application effect and experience of technology In some domestic cleaning station. By Comprehensive evaluation of the technical and economic aspects, this process is viewed to a new technology that it is Safe, reliable, affordable in the high turbidity water purification Recently,and it has high popularization value.The body of clarifier is steel reinforced concrete structure in general, By composition of pool wall, column, wall and various support mainly. The new clarifier used frame-shear wall structure form, fully combined to the characteristics of rectangular pools and circular pool, but the whole system structure form is complex, the research of clarify pool structure form is very few in domestic, this paper With structure optimization of the "HPS clarifier" in gansu jinqiao water design and engineering (group) Co., LTD. In "pucheng clean energy chemical industry limited liability company coal chemical industry park because of180tons methanol700000tons of polyolefin plant water supply project the purification project" in is in the background, in the finite element way, the research work are as follows:(1) the research and analysis of the features of the structure of the traditional clarifier which combined with the process requirement, put forward the new clarifier structure. Through calculating, summarizing the deficiencies of the new type of the original clarification structure design, according to the structure, s load characteristics and the special requirements of technology, according to practical situation, proposed the new-style clarifier after optimization.(2) Used a large-scale finite element analysis software MIDAS/Gen, according to the finite element theory knowledge and the characteristics of the clarification, clearing structure, s the load condition and constraint conditions, we establish structure the clarification model of the original and optimized water clarification.(3) according to analysis two structure in static, modal and seismic response spectrum, it found the structure, distribution law of mechanical characteristics and stress and deformation.in the static, dynamic of.Through the comparative analysis, it verified the effectiveness of the new-style clarifier after optimization model in the bearing capacity and economic advantage, to provide reference for the engineering design. (4) Used common concrete clarifier structure, pulling force of the optimal level pull beam is bigger, it is difficult to meet the requirements of degree of crack-resistance, suggested the prestressed concrete structure.This paper researches on the new-style clarifier structure design calculation can provide reference value, have the important meaning for popularization and application for new-style clarifier structure in the domestic.
