Design method of high-temperature electric precipitator structure

Abstract

The invention discloses a design method of a high-temperature electric precipitator structure. The design method of the high-temperature electric precipitator structure comprises the following steps:firstly, establishing a three-dimensional model for an electric precipitator according to an actual structure form to form an independent closed system; and then inputting various structural stresses,and enabling the structural strength of the electric precipitator to adapt to a high-temperature working environment through model calculation and structural model selection optimization. The high-temperature electric dust remover has the beneficial effects that through computer modeling and special structural design, the structure of the high-temperature electric dust remover is optimized, the stability of the stand column of the shell is enhanced, the deformation resistance of the shell of the dust remover is enhanced, and the effects of wind loads, temperature loads and internal negative pressure on the dust remover during equipment operation can be better resisted. The shell stand column is connected with the electric precipitation internal steel pipe support, so that a stable structural system can be formed.

Description

technical field [0001] The invention relates to the field of high-temperature electric dust collectors, in particular to a design method for the structure of high-temperature electric dust collectors. Background technique [0002] The dust collector is a high-efficiency dust removal equipment used to collect fine dust. It uses high-voltage direct current to separate solid particles from the airflow, thereby purifying the dusty flue gas. The electrostatic precipitator consists of three parts: the electrostatic precipitator body, the electric control device, and the supporting frame. Among them, the electrostatic precipitator body is composed of inlet reducing pipe, outlet reducing pipe, shell frame, ash bucket, wallboard, pipeline and heat preservation. (see figure 1 ) [0003] The shell of the electrostatic precipitator can be divided into two parts, one part is the steel frame that bears the entire structural weight of the electrostatic precipitator and the external addi...

Problems solved by technology

[0006] For high-temperature electrostatic precipitators, the high temperature of hundreds of degrees during operation causes structural expansion and deformation. The traditional medium and low temperature structural design models and methods cannot meet the requirements for structural strength in the working state, which may easily cause deformation and tearing of the shell structure and damage the structure of the precipitator. , causing a serious security risk
