By this way, the ability of students using basic knowledge and specialized knowledge to solve series of problems in productive practice can be obtained. By solving problems constantly, our understanding and practicing of knowledge can be improved。 by the guiding of teachers and reading of technical materials, our knowledge area can be enlarged. Therefore, graduation design plays an important role in adjusting in the future job and society for students. This design is to manufacture reagent tannin with nutgall. It aims to have an overall understanding of the process and procedure of producing reagent tannin, and to master the basic method and entire procedure of chemical process design and equipment design. This design content includes the following aspects: 1. Calculation of process design: choosing and proofing of flow, calculating of material and heat。 2. Equipment design calculation and model choosing。 3. 1 copy of shop process flow chart 4. 1 copy of evaporator equipment drawing。 5. 1 copy of evaporator equipment design instructions。 6. 1 copy of shop plan view。 7. 1 copy of shop economic analysis and evaluation. 3 目 錄 1. 設(shè)計(jì)任務(wù) 設(shè)計(jì)任務(wù) ......................................................................................................................... 2 設(shè)計(jì) 依據(jù) ......................................................................................................................... 2 2. 選擇生產(chǎn)方法，確定生產(chǎn)工藝與流程 .................................................................................. 4 廠址選擇 ............................................................................................................................ 4 生產(chǎn)方法的選擇 ............................................................................................................... 5 五倍子原料及單寧產(chǎn)品的特性 ....................................................................................... 5 主要工段工藝條件 ............................................................................................................ 6 生產(chǎn)方法的選擇 ................................................................................................................ 7 確定生產(chǎn)工藝流程路線 ................................................................................................. 14 3. 物料衡算 .................................................................................................................................. 14 物料衡算的計(jì)算基準(zhǔn) ................................................................................................... 14 每小時生產(chǎn)能力計(jì)算 ..................................................................................................... 15 畫出生產(chǎn)流程圖，標(biāo)出相關(guān)數(shù)據(jù)，然 后進(jìn)行計(jì)算 ..................................................... 15 純度計(jì)算 .......................................................................................................................... 15 進(jìn)料各工段物料計(jì)算 ...................................................................................................... 16 物料總衡算 ........................................................................................................... 16 噴霧干燥工段 ........................................................................................................ 16 干燥工段損失部分的組分和數(shù)量 ....................................................................... 16 蒸發(fā)工段 ............................................................................................................... 16 浸提工段 ............................................................................................................... 16 浸提工段損失部分的組分及數(shù)量 ....................................................................... 17 4 備料工段 ............................................................................................................... 17 未經(jīng)粉碎的原料的組分和數(shù)量 ........................................................................... 17 備料工段損失部分的組分及數(shù)量 ....................................................................... 18 4. 設(shè)備設(shè)計(jì)及熱量衡算 .............................................................................................................. 18 備料工段 .......................................................................................................................... 18 電瓶車 ................................................................................................................... 18 皮帶輸送機(jī) ........................................................................................................... 18 旋風(fēng)分離器 ........................................................................................................... 20 粉碎機(jī) ................................................................................................................... 20 振動篩 .................................................................................................................... 21 初級振動篩的吸塵裝置 ........................................................................................ 21 貯灰斗 ................................................................................................................... 21
