1、摘要哈爾濱糧庫鍋爐房位于哈爾濱市,該鍋爐房是為了滿足哈爾濱糧庫的工業(yè)生產(chǎn)用汽和廠內(nèi)員工住宅的采暖、生活、通風(fēng)的用汽所建的工業(yè)鍋爐房。本工程屬哈爾濱糧庫獨資建設(shè)項目。本設(shè)計的內(nèi)容主要包括鍋爐的選型、鍋爐給水水處理系統(tǒng)、鍋爐送引風(fēng)系統(tǒng)、運(yùn)煤除渣系統(tǒng)的設(shè)計。本工程選用了2臺重慶鍋爐總廠生產(chǎn)的SHL10-1.27/350-AⅢ型蒸汽鍋爐,燃用哈爾濱煙煤。鍋爐給水水處理系統(tǒng)采用固定床逆流再生單級鈉離子交換器做軟化處理。除氧方式為熱力除氧,故選擇噴霧式全補(bǔ)水熱力除氧器。鍋爐送引風(fēng)系統(tǒng)采用鼓風(fēng)機(jī)和送風(fēng)機(jī)配合使用,鼓風(fēng)機(jī)用于克服風(fēng)道與燃燒設(shè)備的阻力
2、,引風(fēng)機(jī)用于克服鍋爐本體煙道、煙囪及除塵器的阻力。在煙氣處理過程中,為符合煙氣排放標(biāo)準(zhǔn),故采用STC-3系列除塵器對煙氣進(jìn)行脫硫除塵。在運(yùn)煤除渣系統(tǒng)中,因耗煤量較大,所以采用機(jī)械化運(yùn)煤方式,故選用Z型埋刮板輸送機(jī),同時配備RCD型磁選裝置、錘式反沖擊破碎機(jī)等設(shè)備。由于本鍋爐系統(tǒng)為雙鍋筒橫置式鏈條爐排,鍋爐要求連續(xù)除渣,故采用了重鏈?zhǔn)匠鼨C(jī),灰渣由汽車直接運(yùn)走,不需設(shè)置灰渣場。本鍋爐房分三層布置。一層布置泵房、水處理間、配電室及門衛(wèi);二層布置控制室、更衣室、沐浴室及辦公室;三層布置除氧間。引送風(fēng)機(jī)、除塵器布置在風(fēng)機(jī)間內(nèi)。關(guān)鍵詞:鍋爐;
