By the physicochemical properties of ether and storage process to set the storage tank area in the factory. According to the production processes and storage places of the petrochemical enterprises for fire protection design analysis to determine the fire risk category. Then based on the petrochemical enterprises for fire protection design and archi tectural design fire code GB5001620xx to determine the spacing of the main building fire in the factory, and regional planning and layout of the storage tank area. Select a tank fire risk area under the explosion and fire hazard, electrical installation design specifications, the specifications of the fire of the fire danger zone dike, explosionproof electrical equipment and storage tank area analyzed. Understanding of the storage place of the fire hazard category, set the production sites of the storage tank area, and ancillary facilities, the construction of the storage area, the function of structures to determine to build, build a fire resistance rating. Layout diagram to draw tanks Chief. Keywords: fire risk, fire resistance rating and spacing of fire, explosionproof electrical equipment, fire extinguishers 防火防爆課程設(shè)計(jì)說(shuō)明書(shū) III 目錄 摘要 ………………………………………………………………………… I ………………………… …………………………………………… 1 、爆炸危險(xiǎn)性 … ………… ……………… …………… …………… 2 揮發(fā)性 ????????????????????????? 2 流動(dòng) /擴(kuò)散性 ??????????????????????? 2 高易燃性 ???????????????????????? 2 蒸氣的易爆性 ??? ? ???? ?????????????? 3 熱膨脹性 ???????????????????????? 3 聚積靜電荷性 ?????????????????????? 3 …………………………………………………………… 4 可燃物質(zhì)的火災(zāi)危險(xiǎn)性分類(lèi) ???????????????? 4 選址和布置 ????????????????????? ?? 4 罐區(qū)與周?chē)O(shè)施的安全距離 ????????????? ?? 4 罐區(qū)建 (構(gòu) )筑物之間的防火間距 ????????????? 5 儲(chǔ) 罐之間的防火間距 ?????????????????? 6 儲(chǔ)罐型式 ???????????????????????? 7 建 (構(gòu) )筑物的耐火等級(jí) ?????????????????? 7 電氣的防爆 ??????????????????????? 7 爆炸危險(xiǎn)環(huán)境區(qū)域劃分 ??????? ?????????? 8 爆炸危險(xiǎn)區(qū)域的范圍確定 ???????????????? 8 爆炸性混合物的分類(lèi)、分級(jí)和分組 ???????????? 8 乙醚罐區(qū)的電氣設(shè)計(jì)要點(diǎn) ???????????????? 8 控制乙醚蒸氣與空氣混合物的濃度 ????????????? 9 減少蒸氣排放 ????????????????????? 9 通風(fēng) ????????????????????????? 9 惰化 ????????????????????????? 9 設(shè)置阻火器 ??????????????????????? 10 管道與閥門(mén) ??????????????????????? 10 噴淋冷卻 ???????????????????????? 10 防火防爆課程設(shè)計(jì)說(shuō)明書(shū) IV 防止靜電與雷擊 ????????????????????? 10 防止靜電 ??????????????????????? 10 防止雷擊 ??????????????????????? 11 消防設(shè)施 ???????????????????????? 11 可燃?xì)怏w報(bào)警及聯(lián)動(dòng)系統(tǒng) ???????????????? 12 滅火系統(tǒng) ??????????????????????? 12 結(jié)論 ……………………………………………………… 15 罐區(qū)規(guī)劃 ???????????????????????? 15 廠(chǎng)址及總平面布置 ??????????????????? 15 油罐組防火堤的布置 ?????????????????? 16 安全距離及道路 ???????????????????? 16 建 (構(gòu) )筑物及附屬設(shè)備 ????????????????? 16 滅火設(shè)施 ??????????????????????? 17 過(guò)程 /設(shè)備設(shè)計(jì)?????????????????????? 17 ……………………………………………………………………… 19 參考文獻(xiàn) ……………… …………………………………………………… 20 防火防爆課程設(shè)計(jì)說(shuō)明書(shū) 1
