【正文】 工業(yè)除塵與通風(fēng)課程設(shè)計 I 摘 要 在 煤廠 進(jìn)行生產(chǎn)的過程中散發(fā)的各種有害物粉塵（主要為 煤塵 塵）、有害蒸汽和氣體以及余熱如果不加控制會使室內(nèi)空氣環(huán)境受到污染和破壞，危害人的健康，影響生產(chǎn)的正常進(jìn)行和實驗的效率。因此，有效的控制生產(chǎn)過程中有害物對室內(nèi)空氣的影響和破壞是一個非常重要的問題。工業(yè)通風(fēng)就是研究這方面問題的一門技術(shù)。本設(shè)計為 山西洗煤廠 處理工部的通風(fēng)除塵系統(tǒng)設(shè)計。首先，結(jié)合工程查閱相關(guān)的資料分析確定該 洗煤廠所產(chǎn)生的粉塵的主要類型與性質(zhì)，根據(jù)粉塵的類型與性質(zhì)選擇合適的集氣罩和除塵器。然后，根據(jù)規(guī)范的要求提出了通風(fēng)除塵系統(tǒng)的設(shè)計方案并 進(jìn)行管道布置。根據(jù)工藝選擇排風(fēng)罩罩口形式并計算排風(fēng)量。確定管道斷面形式及尺寸進(jìn)行水力計算選擇凈化設(shè)備和風(fēng)機的型號。選擇風(fēng)管的管材及其安裝方式。最后繪制除塵系統(tǒng)的結(jié)構(gòu)簡圖。 考慮到 煤廠 粉塵污染的特點以及工藝操作的限制，比較各種類型的除塵器，選擇了最合理的通風(fēng)除塵方案，進(jìn)行了通風(fēng)除塵系統(tǒng)的設(shè)計。 關(guān)鍵詞 : 通風(fēng)；除塵；設(shè)計；工業(yè)除塵與通風(fēng)課程設(shè)計 1 Abstract In foundry production process with various harmful dust ( mainly for sand and dust ), harmful steam and gases and heat if not controlled can make indoor air `environment pollution and destruction, harmful to human health, affect the normal production and experimental efficiency. Therefore, effective control of production process of harmful effects of indoor air and damage is a very important problem. Industrial ventilation is studying this issue of a design of Zhejiang’package foundry dust ventilation system design. First, the bination of engineering analysis to determine the type and nature of the dust generated by the foundry access relevant information to select the appropriate set of hood and dust, according to the type and nature of the , according to passes the requirements of the standards, puts forward the ventilation dust removal system design scheme, and piping layout. According to the technology choice exhaust envelope mouth forms of, and calculate the exhaust air. Sure pipe section mode and dimensions, the hydraulic calculation, choose purification equipment and fan models. Choose the pipes and the installation way duct. Finally draw the dedusting system structure diagram. Considering the characteristics of dust pollution as well as the workshop process operation constraints, parison of various types of dust collector, to choose the most reasonable ventilation dust removal scheme, the ventilation and dust removal system design. Keywords: casting ventilation； dust removal； design； hydraulic calculation 工業(yè)除塵與通風(fēng)課程設(shè)計 1 摘 要 I Abstract 1 前言 1 1 工廠簡介 2 2 粉塵 3 粉塵的定義 3 粉塵的分類 3 粉塵的性質(zhì) 3 密度 3 粘附性 3 爆炸性 4 荷電性與比電阻 4 顆粒物的潤濕性 4 顆 粒物的粒徑及粒徑分布 18
