You and I will have the chance to watch a man take a leap into an unimaginable free fall from the edge of space live. The (lack of) air up there Watch man jump from 96,000 feet Tuesday, I sat at work glued to the live stream of the Red Bull Stratos Mission. I watched the balloons positioned at different altitudes in the sky to test the winds, knowing that if they would just line up in a vertical straight line we would be go for launch. I feel this mission was created for me because I am also a journalist and a photographer, but above all I live for taking a leap of faith the feeling of pushing the envelope into uncharted territory. 專業(yè)好文檔 The guy who is going to do this, Felix Baumgartner, must have that same feeling, at a level I will never reach. However, it did not stop me from feeling his pain when a gust of swirling wind kicked up and twisted the partially filled balloon that would take him to the upper end of our atmosphere. As soon as the 40acre balloon, with skin no thicker than a dry cleaning bag, scraped the ground I knew it was over. How claustrophobia almost grounded supersonic skydiver With each twist, you could see the wrinkles of disappointment on the face of the current record holder and cap (capsule munications), Col. Joe Kittinger. He hung his head low in mission control as he told Baumgartner the disappointing news: Mission aborted. The supersonic descent could happen as early as Sunday. The weather plays an important role in this mission. Starting at the ground, conditions have to be very calm winds less than 2 mph, with no precipitation or humidity and limited cloud cover. The balloon, with capsule attached, will move through the lower level of the atmosphere (the troposphere) where our daytoday weather lives. It will climb higher than the tip of Mount Everest ( miles/ kilometers), drifting even higher than the cruising altitude of mercial airliners ( miles/ kilometers) and into the stratosphere. As he crosses the boundary layer (called the tropopause), he can expect a lot of turbulence. The balloon will slowly drift to the edge of space at 120,000 feet ( miles/ kilometers). Here, Fearless Felix will unclip. He will roll back the door. Then, I would assume, he will slowly step out onto something resembling an Olympic diving platform. Below, the Earth bees the concrete bottom of a swimming pool that he wants to land on, but not too hard. Still, he39。s first satellite Sputnik. I also missed watching Neil Armstrong step foot on the moon and the first space shuttle take off for the stars. Those events were way before my time. As a kid, I was fascinated with what goes on in the sky, and when NASA pulled the plug on the shuttle program I was heartbroken. Yet the privatized space race has renewed my childhood dreams to reach for the stars. As a meteorologist, I39。 專業(yè)好文檔 ㈣本項(xiàng)目年可為國(guó)家交納稅金 38萬(wàn)元,企業(yè) 效益也相當(dāng)可觀。 ㈦貸款償還年限本項(xiàng)目?jī)H作資金流量靜態(tài)分析后得知全部資金 8 年收回(含流動(dòng)資金),如若將流動(dòng)資金別除,再加上年利潤(rùn)也作為還貸,全部資金可望于 56年收回。10000T=28元 包裝物:噸輕鈣需包裝袋 40 個(gè),內(nèi)復(fù)膜塑料包裝袋每只 ,計(jì) 44元。8 年 247。 9噸 /T= 低值易耗品(含修理費(fèi)及勞保用品)每噸 25元。 七、輕鈣產(chǎn)品單位成本計(jì)算: 以生產(chǎn) 1噸產(chǎn)品計(jì): 元 /噸 ㈠成本構(gòu)成: 石灰石:噸產(chǎn)品耗石灰石 噸,每噸石灰石成本 8元, 8元 /T= 燃料(無(wú)煙煤):綜合煤耗 。 ㈣原煤入爐前為了防粉塵飛揚(yáng),作噴水防塵處理。 六、項(xiàng)目環(huán)保措施 ㈠采石 場(chǎng)石灰石撲破及破碎均為開放式生產(chǎn),有少量粉塵排放,生產(chǎn)人員帶防塵口罩可避免粉塵吸入肺部。 石灰燒成后,經(jīng)冷卻至 80℃ 以下,送入化灰機(jī),以石灰4倍的水混合進(jìn)行消化反應(yīng),生成石灰乳漿 ,經(jīng)調(diào)和過篩,再經(jīng)旋葉分離器分離后進(jìn)入貯漿池,等待碳化。 四、輕質(zhì)碳酸鈣產(chǎn)品生產(chǎn)原料主要技術(shù)指標(biāo)和工藝過程 專業(yè)好文檔 ㈠石灰石:破碎成 80180mm塊狀 指標(biāo)名稱 數(shù)(含)量 CaC03 % ≥ 98 SiO2 % ≤ Mgo % ≤ 1 Mn %≤ Fe %≥ ㈡無(wú)煙煤 指標(biāo)名稱 指標(biāo)要求 發(fā)熱量 /kg > 4500 大卡/kg 揮發(fā)份 %≤ 6 灰份 %≤ 12 固定碳 %≥ 80 ㈢主要原材料消耗 每燒成一噸石灰耗 石灰石 ,耗用無(wú)煙煤 。 利用坡地自然地勢(shì),既不侵占農(nóng)田,又可優(yōu)化工藝流程,降低投資。 ㈢選址依據(jù) 該廠址距景白公路較遠(yuǎn),相對(duì)隱蔽,屬非村莊 人口流量偏少地段。 充分考慮礦石開采和爆破產(chǎn)生的粉塵及噪音較大的因素,必須遠(yuǎn)離村莊和人員流動(dòng)量大的場(chǎng)所。就目前江西、浙江兩省輕鈣產(chǎn)量約年 40萬(wàn)噸,僅浙江溫州地區(qū)的年消耗量就大大超出供應(yīng)量,每年還千里迢迢到豫、晉等地進(jìn)貨,可見輕鈣市場(chǎng)需要量將繼續(xù)保持穩(wěn)步增長(zhǎng)的態(tài)勢(shì)。 輕質(zhì)碳酸鈣作為化學(xué)工業(yè)原料,它不僅是一種優(yōu)良的填充劑,同時(shí)又是一種理想的改性劑,并廣泛用于:橡膠工業(yè)、塑料工業(yè)、造紙工業(yè)、建材工業(yè)等方面。 項(xiàng) 目名稱: XX縣 XX鎮(zhèn)輕質(zhì)碳酸鈣有限公司 ⑴ 項(xiàng)目規(guī)模:年產(chǎn)輕質(zhì)碳酸鈣 10000噸。 XX鎮(zhèn)多年來一直雄踞 XX縣經(jīng)濟(jì)發(fā)展的榜首。該鎮(zhèn)礦產(chǎn)資源豐富,近年該鎮(zhèn)人文及自然景觀的開發(fā),為該鎮(zhèn)經(jīng)濟(jì)的迅速掘起,再次插上了騰飛的翅膀。 項(xiàng)目宗旨:以高起點(diǎn)的設(shè)計(jì),先進(jìn)的工藝流程,現(xiàn)代化的管理模式和優(yōu)質(zhì)的產(chǎn)品擠身并占領(lǐng)碳酸鈣市場(chǎng)。其分子式: caco3,產(chǎn)品外觀呈白色粉末狀,無(wú)味,難溶于水和醇,可溶于酸,具有與有機(jī)物很好的親和力的特點(diǎn),并有專業(yè)好文檔 一定的吸潮性。 隨著我國(guó)經(jīng)濟(jì)建設(shè)的迅猛發(fā)展,人民生活水平的不斷提高和消費(fèi)結(jié)構(gòu)的變化,橡膠、塑料、建材行業(yè)對(duì)輕鈣的需求將不斷攀升,尤其是輪胎、鞋業(yè)等制造工業(yè)對(duì)輕鈣的需求量將是空前的。 三、廠址選擇 ㈠廠址選擇的原則 充分考慮景白公路綠色長(zhǎng)廊沿線景色,不被破壞,在專業(yè)好文檔 保護(hù)生態(tài)植被的同時(shí),本著維護(hù) XX 生態(tài)旅游示范區(qū)整體景觀的原則。 ㈡廠址的確定 基于上述選址原則,廠址選定: XX鎮(zhèn)洪源塢大山腳下(土名)。故不污染飲用水源。 因此,該點(diǎn)作為建廠廠址,具有得天獨(dú)厚的有利條件。被抽走的窯氣由管經(jīng)旋風(fēng)除塵器除塵后,經(jīng)篩板式洗滌塔,經(jīng)氣水分離器后,進(jìn)入另一臺(tái)空壓機(jī)車入至儲(chǔ)氣罐后入碳化塔與從貯漿池來 的石灰乳漿作碳化處理。 5 提升機(jī) (窯房 ) 1 6 洗滌塔 1 10 7 漿泵 3 8 脫水機(jī) 3 3 9 旋液分離器 3 10 螺旋輸運(yùn)機(jī) 1 11 皮帶運(yùn)輸機(jī) 1 12 烘干干燥機(jī) (鍋爐 ) 1 50 13 分料盤 1 14 篩分機(jī) 1 12 15 供水、輸送管線 5 16 化驗(yàn)器具 一套 3 17 輸電線路 10KV 700m 7 18 變壓器 350KVA 7 19 電控裝置 6 20 電焊機(jī) 直流 500 型 1 21 工具 22 設(shè)備運(yùn)雜安裝費(fèi)等 25 23 不可預(yù)見費(fèi) 3 24 合計(jì) 專業(yè)好文檔 上述三項(xiàng)合計(jì):該項(xiàng)目共需資金 350萬(wàn)元。經(jīng)化灰后殘碴,集中存入,與鍋爐爐碴待具有一定量后,作生產(chǎn)碴磚原料加工成才(磚)出售。 ㈦包裝工序基本無(wú)粉塵:工人戴普通口罩可保障人身安全 ,由于碳酸鈣含鈣高對(duì)人體一般沒有職業(yè)性危害。 130度 /度 = 水:綜合水耗 18噸,每噸水 ,經(jīng)循環(huán)使用實(shí)耗9噸。10000T/月 = 折舊費(fèi):該項(xiàng)目共需資金 350萬(wàn)元,計(jì)劃 8年收回全部投資,折舊費(fèi)用于還貸款,噸產(chǎn)品應(yīng)提: 350萬(wàn)元 247。 350萬(wàn)元 8%247。 九、項(xiàng)目效益分析 ㈠年銷售收 : 450萬(wàn)元; ㈡年工業(yè)產(chǎn)值: 450萬(wàn)元; ㈢年實(shí)現(xiàn)稅金: 38萬(wàn)元; ㈣年實(shí)現(xiàn)利潤(rùn): ; ㈤年提取折舊費(fèi): (全部用于還貸款) ㈥盈虧平衡點(diǎn)計(jì) 算 產(chǎn)量保本點(diǎn) 產(chǎn)量保本點(diǎn) = = =5423(噸) 年產(chǎn) 5423噸可保本。 ㈢本項(xiàng)目實(shí)施后,可提供就業(yè)機(jī)會(huì) 90人,有一定社會(huì)效益。s note: Judson Jones is a meteorologist, journalist and photographer.
