AI Technical Summary

Problems solved by technology

However, at present, there is no standard design theory for the design of the main structure of the electrostatic precipitator. During manufacturing, the design is generally carried out by analogy, and the determination of component material distribution and cross-sectional size is blind, resulting in a large waste of materials.

Embodiment

[0036] Taking a typical smoke box structure of a large electrostatic precipitator as an example, figure 1 , 2 shows a typical traditional smoke box structure, which is composed of wall panels 12, struts 11 and ribs 10. Depend on figure 1 It can be seen that the reinforcing ribs 10 in the traditional smoke box structure are basically evenly distributed parallel ribs.

[0037] (1) Design of reinforcement rib distribution of smoke box structure based on adaptive growth method

[0038] The self-adaptive growth design method is proposed based on the growth mechanism of the branch system in nature. Under the given load and support conditions, the shell element is used to simulate the thin plate shell, and the beam element is used to simulate the stiffener. The beam element of is used as the initial growing rib. On the basis of the finite element analysis, the sensitivity analysis of the growing rib is carried out, and the height of the growing rib is updated according to the heigh...

Abstract

The invention relates to an optimal design method of a smoke box structure of a large electric precipitator. The method includes: optimally designing distribution of reinforcing ribs of the smoke box structure: a design model only comprises a wall plate and a supporting rod, a self-adapting growth method based on the nature branch net morphosis mechanism is adopted, and distribution of the reinforcing ribs of a smoke box is designed with minimum structure strain energy as the design target and under the condition of reinforcing rib volume limiting; and optimally designing dimensions of structure parameters of the smoke box in details with minimum structure mass as the design target and under the condition of meeting structural strength and rigidity requirements, and therefore an optimum smoke box structure with high rigidity and strength and low mass is obtained.

Description

technical field [0001] The invention relates to a method for designing the smoke box structure of an electrostatic precipitator, in particular to a method for designing the reinforcing rib distribution of the smoke box through an adaptive growth method based on the growth mechanism of the branch network in nature, and adopting a size optimization method to make the smoke box structure An optimal design method to meet the design requirements of high stiffness, high strength and light weight. Background technique [0002] Large-scale electrostatic precipitator is a kind of smoke and dust purification equipment to control air pollution. It is more and more widely used in many industries due to its remarkable advantages such as high efficiency, energy saving, and easy maintenance. However, there is currently no standard design theory for the design of the main structure of the electrostatic precipitator. During manufacturing, the design is generally carried out by analogy. The d...
