【摘要】：隨著我國環(huán)境污染問題的日趨嚴重,現在政府以《環(huán)境保護法》為有力武器,加大對環(huán)境污染的監(jiān)督檢查和處罰力度。大氣污染是我國現階段環(huán)境污染的主要成分之一。其主要表現是:以燃煤排放的煙塵和二氧化硫為主要污染物的大氣污染;粉塵是大氣環(huán)境中涉及面最廣、危害最嚴重的一種污染物。中國大氣污染主要是由燃煤造成的。主要污染物是煙塵和二氧化硫。末端治理仍是我國長期以來治理環(huán)境污染的一種基本手段。電除塵器是治理燃煤排放的煙塵的主要手段之一。隨著電除塵器單臺處理煙氣量越來越大及排放濃度越來越小,電除塵器也越做越大,單臺長、寬、高經常達到35×30×25米,其是大跨度空間結構設備,因此其單臺鋼耗量也越來越大,經常單臺重量達到1000多噸,其單臺造價也越來越高,因此要對電除塵器進行結構優(yōu)化設計降低鋼耗量,提高企業(yè)產品市場競爭力。針對電除塵器存在的問題,通過調研、分析、對比各種優(yōu)化分析方法,本文采用STAAD結構計算分析軟件對電除塵器結構的零部件進行了有限元分析與設計,并根據軟件分析計算結果,對電除塵器的進氣口、出氣口、灰斗、電除塵器的底梁、進出氣端端墻及頂梁等結構的主要承重部件進行了優(yōu)化設計,優(yōu)化結果表明,這樣既增加了結構的穩(wěn)定性又充分的利用了材料的性能,減輕了設備的重量,降低了成本,提高了產品性價比,提高了產品的市場競爭力。
[Abstract]:With the increasingly serious problem of environmental pollution in China, the government is now using the Environmental Protection Law as a powerful weapon. Air pollution is one of the main components of environmental pollution in our country at present. Its main manifestation is: air pollution with smoke and sulfur dioxide from coal combustion as the main pollutants; Dust is the most extensive in the atmospheric environment. The air pollution in China is mainly caused by coal combustion. The main pollutants are soot and sulfur dioxide. Terminal control is still a basic means of environmental pollution control in China for a long time. The dust collector is one of the main methods to control the smoke and dust from coal combustion. As the amount of flue gas is increasing and the emission concentration is becoming smaller and smaller by the single ESP, The electrostatic precipitator is becoming bigger and bigger, with a single length, width and height of 35 脳 30 脳 25 meters. It is a large span space structure equipment. Therefore, its steel consumption per unit is also increasing, and the weight of a single unit is often more than 1000 tons, and the cost of a single unit is increasing. Therefore, it is necessary to optimize the structure design of ESP to reduce steel consumption and improve the market competitiveness of enterprise products. In view of the problems existing in ESP, through investigation, analysis and comparison of various optimization analysis methods, In this paper, the finite element analysis and design of the structure parts of the electrostatic precipitator are carried out by using the STAAD structure calculation and analysis software. According to the results of the analysis and calculation of the software, the air inlet, the outlet, the ash hopper and the bottom beam of the electrostatic precipitator are analyzed. The optimum design of the main load-bearing parts of the structure, such as the end wall and the top beam, is carried out. The optimization results show that the stability of the structure is increased, the performance of the material is fully utilized, the weight of the equipment is reduced, and the cost is reduced. Improve the product price-performance ratio, improve the market competitiveness of the product.
