【正文】 te in China hav being upto 29, and the plants having 3000 t to 10000 t, being upto 85.The aluminum sulfate production capacity has reached million t, yield breakthroughs 950,000 t, after the United States and Japan, the third in the world live。Aluminum sulfate production in the problem is that the unreasonable design, equipment is not supporting, yield and quality are unable to meet its mind and requested some smaller manufacturers, leading to poor economic returns serious backlog of products, investment is not possible, so that some enterprises back heavy The economic burden of production of a major Al Grey, Al Jardine, of aluminum hydroxide, bauxite atmospheric pressure, such as coal gangue pression method, all of the advantages and disadvantages pared to that of raw materials for the production of kaolin Aluminum sulfate, a lowcost raw materials, high yield, good quality products, processcontrol advantages, in the course of preparation of the highactivity waste residue can be used as the highsilicon material, but also as a fine of paint and sheet metal products fill, so as to achieve a prehensive Use and no waste residue emissions, have a positive environmental significance of raw materials used for the production of kaolin aluminum sulfate, with the design of purpose and guiding ideology.Kaolin production of aluminum sulfate, kaolin After pretreatment process, rule out the possibility of kaolin in the rough quartz sand, impurities, the glass used in the production of cement, by Kaolin concentrate, after calcination activated, crushing, screening sent to the production workshop, with 55 percent of the sulfuric acid Mixed easily sent to the reactor, the reaction of acid leaching, settlement, and in the separation and processing of aluminum sulfate be qualified easily, and sent to concentration crystallization tank, concentrated fruit and refined through the grinder will crush aluminum sulfate crystals, Packaging.在造紙工業(yè)中可作紙的填料和處理造紙工業(yè)廢水。（1）流程示意圖（2）反應(yīng)式A l2O32H2O+3H2SO4+13H2O→Al2(SO4)3+㎏/hh0kJ/㎏Q=%+(1－%) =103kJ求得Al2(SO4)103kJ。103kJ，Al2(SO4)103kJ，103kJ。熱量衡算表入料吸熱(103kJ)硫酸浸取高嶺土中氧化鋁的反應(yīng)是典型的液固反應(yīng)，物料在反應(yīng)過程中的體積基本不變。一般說來，在滿足工藝要求的CA0和XB時，通過式(7)計算平均反應(yīng)時間和反應(yīng)溫度的關(guān)系，然后綜合考慮設(shè)備投資和操作費用，選擇適宜的反應(yīng)溫度和平均反應(yīng)時間，再計算反應(yīng)器容積?？紤]到搪鉛工藝的實施和搪鉛時的鉛中毒， 釜體和釜蓋須采用法蘭連接。簡擺顎式破碎機結(jié)構(gòu)緊湊簡單，偏心軸等傳動件受力較?。挥捎趧宇€垂直位移較小，加工時物料較少有過度破碎的現(xiàn)象，動顎顎板的磨損較小。其位于磨輥下端，鏟刀與磨輥同轉(zhuǎn)過程中把物料鏟起拋喂入磨輥輥環(huán)之間，形成墊料層，該料層受磨輥旋轉(zhuǎn)產(chǎn)生向外的擠壓力將物料碾碎，由此達(dá)到制粉目的。注：提升機輸運物料至料倉一定量后，先停止破碎機而后再停止提升，此項應(yīng)由儲料量現(xiàn)時變動。在過濾理論研究方面，濾渣層過濾阻力和孔隙率的測算、過濾速度、過濾設(shè)備的模擬和放大、稀薄液體澄清過濾和動態(tài)過濾機理，以及過濾介質(zhì)的研究，都是重要的課題。表12 一些主要設(shè)備表序號名稱數(shù)量主要參數(shù)功率ＫＷ總價萬元供貨單位1顎式破碎機2臺破碎抗壓強度不超過320兆帕2河南紅星礦山機器有限公司設(shè)計2雷蒙磨2臺最大進(jìn)料細(xì)度15 20mm1550鄭州市宏科機械設(shè)備有限公司3反應(yīng)釜4個℃1750大連通達(dá)反應(yīng)釜廠4煅燒爐120定制5板式過濾機2個33宜 興 市 精 益 機 械 廠6濃縮結(jié)晶鍋4個夾套直徑Φ1500筒體直徑Φ140020無錫市雪浪發(fā)酵工程設(shè)備廠7成品粉碎機2臺1310定貨總計68185[17]由于此工藝反應(yīng)過程中硫酸不易揮發(fā)，所以基本不產(chǎn)生廢氣；工藝流程中酸不斷的被稀釋并與高嶺土反應(yīng)，所以最后少量酸性廢水經(jīng)過中和后可以直接排放；廢渣則可用于制造水泥及濕法生產(chǎn)高模數(shù)水玻璃。 廠房層數(shù)的設(shè)計要根據(jù)工藝流程的要求、投資、用地的條件等各種因素，進(jìn)行綜合的比較，然后才能最后決定。 廠房的寬度問題，生產(chǎn)廠方為了盡可能利用自然采光和通風(fēng)以及建筑經(jīng)濟上的要求，一般單層廠房寬度不宜超過30m，多層廠房寬度不宜超過24m，廠房常用寬度有9m、12m、15m、18m,也有用24m的。廠房的垂直布置要充分利用空間，每層高度取決于設(shè)備的高低、安裝的位置、檢修要求及安全衛(wèi)生等條件。這類廠房還應(yīng)設(shè)置必要的輕質(zhì)屋面、或增加外墻以及門窗的泄壓面積。此外，也可采用室內(nèi)、露天聯(lián)合布置方法。（3）生
