【正文】 股份有限公司和安徽科威金屬材料股份公司的鉛冶煉流程。 生產(chǎn)方法和工藝流程 鉛精礦、河沙、石灰石、碎煤、鐵礦及從余熱鍋爐和電除塵器回收的鉛煙灰通過(guò)配比經(jīng)皮帶機(jī)送到圓盤(pán)制粒機(jī)上被潤(rùn)濕、混合并制成球粒,球粒通過(guò)皮帶機(jī)和可逆配膠帶輸送機(jī)加入到球料倉(cāng)中。)時(shí),經(jīng)烤爐后加入液體鉛和渣,在余熱鍋爐、電除塵、排煙機(jī)、煙灰輸送系統(tǒng)和通風(fēng)系統(tǒng)都投入運(yùn)行后,將底吹爐從準(zhǔn)備位置轉(zhuǎn)至吹煉位置(0176。金屬、爐渣和氣相之間連續(xù)反向流動(dòng),產(chǎn)出的粗鉛從出鉛口虹吸放出,高鉛渣從渣口連續(xù)放出。粗鉛經(jīng)初步火法精煉除去銅,然后經(jīng)電解,陰極析出的鉛經(jīng)熔化鑄錠即得鉛錠產(chǎn)品;陽(yáng)極泥經(jīng)分解,提取銀、銻、鉍等金屬。 生產(chǎn)過(guò)程如下:冶煉車(chē)間除塵器出來(lái)的SO2煙氣進(jìn)入文氏管降溫和除塵,再去泡沫塔進(jìn)一步降溫除塵,文氏管和泡沫塔用稀酸噴淋,淋灑下來(lái)的稀酸循環(huán)使用。發(fā)電機(jī)組采用上海產(chǎn)全套設(shè)備。 總平布置方案 (1)廠址概述 廠址***林場(chǎng),規(guī)劃占地500畝。 (2)總平面布置初步方案 擬將冶煉車(chē)間布置在廠址的西部,其南面布置堆場(chǎng)、地磅,東面為電解車(chē)間,其北面布置為發(fā)電站和硫酸車(chē)間。各建筑在滿(mǎn)足使用要求的前提下力求安全、經(jīng)濟(jì)、美觀大方。 (2)水源泵房、軟水站、制氧站、化驗(yàn)室、地磅房、食堂采用磚混結(jié)構(gòu)。 經(jīng)處理達(dá)到飲用水標(biāo)準(zhǔn)后的井水作為生活用水。 廠區(qū)內(nèi)雨水通過(guò)廠區(qū)內(nèi)的雨水溝匯集后排到廠外。 二、項(xiàng)目建設(shè)過(guò)程中對(duì)環(huán)境的影響及治理措施 在建設(shè)施工過(guò)程中應(yīng)嚴(yán)格控制棄土、揚(yáng)塵、噪聲的影響。廢渣水淬用水循環(huán)使用,不外排,循環(huán)水利用率達(dá)95%以上;制酸車(chē)間排污經(jīng)石灰水中和處理后達(dá)標(biāo)排放。 鉛塵、鉛煙主要產(chǎn)生于配料、輸送和冶煉過(guò)程,本項(xiàng)目采用密封式生產(chǎn),鉛塵、鉛煙等有害氣體的逸出量很少。通過(guò)選用低噪聲設(shè)備、在室內(nèi)安裝、加減震器和隔音罩等措施,可以確保噪聲達(dá)標(biāo)。 (三)冶煉煙氣的余熱用于發(fā)電,年發(fā)電量1800萬(wàn)Kwh/a,大大減少外購(gòu)電量。 (七)做好設(shè)備維護(hù),降低設(shè)備故障,合理安排生產(chǎn),減少頻繁開(kāi)機(jī)、關(guān)機(jī)。 各建筑物根據(jù)情況設(shè)置疏散樓梯及安全出口。第九章 勞動(dòng)保護(hù)和職工安全衛(wèi)生 一、勞動(dòng)保護(hù) 本項(xiàng)目盡可能采取各種措施,改善工人的勞動(dòng)和操作條件,確保工人健康。 (四)對(duì)于生產(chǎn)中產(chǎn)生噪音的地方,盡可能選用低噪音設(shè)備,同時(shí)抑制噪音傳播。 (二)廠區(qū)內(nèi)生產(chǎn)區(qū)和辦公生活區(qū)分開(kāi),人流和貨流盡可能分開(kāi),確保人身安全。 (六)高溫、強(qiáng)電場(chǎng)所設(shè)置明顯警示標(biāo)志。第十章 企業(yè)組織和勞動(dòng)定員 一、企業(yè)組織 企業(yè)實(shí)行董事長(zhǎng)領(lǐng)導(dǎo)下的總經(jīng)理負(fù)責(zé)制,擬設(shè)總經(jīng)理1人,副經(jīng)理2人,并設(shè)銷(xiāo)售部、供應(yīng)部、生產(chǎn)技術(shù)部、財(cái)務(wù)部、后勤保衛(wèi)部、維修部、化驗(yàn)室等職能部門(mén)。第十二章 投資估算及資金籌措 一、投資估算 (一)投資估算范圍 包括平整場(chǎng)地,廠房、辦公用房、職工宿舍、食堂、配電房的建設(shè);設(shè)備購(gòu)置及安裝;供配電工程、給排水工程和道路硬化、圍墻、綠化等工程以及其他費(fèi)用等。 (三)估算結(jié)果 項(xiàng)目總投資估算為45890萬(wàn)元,其中一期建設(shè)投資24145萬(wàn)元,二期投資21745萬(wàn)元建設(shè),詳見(jiàn)附表2。項(xiàng)目計(jì)算期為11年,其中建設(shè)期為1年零6個(gè)月,生產(chǎn)期為9年零6個(gè)月。 增值稅稅率為17%,新企業(yè)所得稅法將于2008年1月1日起實(shí)施,本項(xiàng)目企業(yè)所得稅稅率適用25%。10000=8100萬(wàn)元。10000=。 水電 項(xiàng)目年外購(gòu)電量6800萬(wàn)度,年電費(fèi)為4420萬(wàn)元。 折舊 為便于計(jì)算,無(wú)形資產(chǎn)和遞延資產(chǎn)并入固定資產(chǎn)一起計(jì)提折舊,折舊年限統(tǒng)一取10年,殘值率取5%,折舊額為: 1852695%247。 其他費(fèi)用 包括銷(xiāo)售費(fèi)用等,按銷(xiāo)售收入的2%計(jì),每年為4980萬(wàn)元。 ,產(chǎn)品出廠價(jià)按500元/噸計(jì),年銷(xiāo)售收入為4250萬(wàn)元。 合計(jì)銷(xiāo)售收入為249540萬(wàn)元。 投資利潤(rùn)率:%。 八、財(cái)務(wù)分析結(jié)論本項(xiàng)目財(cái)務(wù)評(píng)價(jià)各項(xiàng)指標(biāo)較好,%,高于基準(zhǔn)收益率;折現(xiàn)率為10%時(shí),財(cái)務(wù)凈現(xiàn)值為30386萬(wàn)元;(含建設(shè)期1年),較短;盈虧平衡分析表明,項(xiàng)目具有較強(qiáng)的抗風(fēng)險(xiǎn)能力。t agree with the disciplinary action your employer has taken against youappealeddamagesbased agreement.
