【摘要】：所謂空分,簡言之就是空氣分離,即將空氣中的主要成分,氧氣、氮?dú)�、二氧化碳以及氬氣等分離出來,達(dá)到各種純度、溫度以及壓力要求的各種產(chǎn)品。所謂空分系統(tǒng),就是要完成上述所有要求的精確可靠的控制系統(tǒng)。 空分由于其行業(yè)特殊性,也存在一些特殊的潛在危險因素,比如：火災(zāi)(純氧),容器爆炸(壓力設(shè)備爆炸),中毒和窒息(高純氣體泄露)以及凍傷等等。普萊克斯作為全球空分行業(yè)中最注重安全生產(chǎn)的公司,對生產(chǎn)運(yùn)營安全非常的重視,反映到我們儀器儀表專業(yè)就是我們有專門的環(huán)境氧檢測系統(tǒng),故障狀態(tài)下的Emergency ShutDown System或者區(qū)域隔離系統(tǒng)以及獨(dú)立的火災(zāi)報警系統(tǒng)和緊急狀態(tài)下的逃生系統(tǒng)等。 本項(xiàng)目是為安徽華誼化工有限公司的配套裝置,主要是按照該廠的生產(chǎn)需求設(shè)計(jì),為該廠配套提供高純度的氧氣和氮?dú)狻Ｖ饕獨(dú)怏w的產(chǎn)量是O2:80000Nm3/h, N2:20000Nm3/h。用氣量比較巨大而且穩(wěn)定,其純度要求在99.5%-99.9%之間,因此本項(xiàng)目選擇深冷分離。 本文的研究目的是運(yùn)用Praxair的專利技術(shù),搭建一套可靠高效節(jié)能環(huán)保的全廠控制系統(tǒng)。主要研究內(nèi)容包括控制平臺的選定,按照既定的工藝參數(shù)進(jìn)行全廠儀表的選型,完成相應(yīng)控制回路的管線以及電路連接圖紙?jiān)O(shè)計(jì),配合軟件部門完成全廠軟件件聯(lián)合調(diào)試,另外還包括設(shè)計(jì)安全的環(huán)境氧檢測系統(tǒng)、火災(zāi)報警系統(tǒng)、逃生系統(tǒng)、區(qū)域隔離系統(tǒng)等等的設(shè)計(jì)與實(shí)施,保證全廠系統(tǒng)全面建立,安全實(shí)施。
[Abstract]:The so-called air separation, in short, is the separation of the main components of the air, oxygen, nitrogen, carbon dioxide, argon and so on, to achieve various purity, temperature and pressure requirements of a variety of products. The so-called air separation system is to complete all the above-mentioned accurate and reliable control system. Because of its industry particularity, air separation also has some special potential risk factors, such as fire (pure oxygen), vessel explosion (pressure equipment explosion), poisoning and asphyxiation (high purity gas leakage) and frostbite, etc. Plaix, as the most safe production company in the global air separation industry, attaches great importance to the safety of production and operation, reflecting that our instrumentation specialty is that we have specialized environmental oxygen detection systems. Fault Emergency ShutDown System or area isolation system, independent fire alarm system and emergency escape system, etc. This project is for Anhui Huayi Chemical Co., Ltd., mainly designed according to the production requirements of the plant to provide high purity oxygen and nitrogen for the plant. The main gas output is O 2: 800 Nm 3 / h, N 2: 200 N m 3 / h. The volume of gas is large and stable, its purity is between 99.5% and 99.9%, so this project chooses cryogenic separation. The purpose of this paper is to set up a set of reliable, high efficiency, energy saving and environmental protection control system by using the patent technology of Praxair. The main research contents include the selection of the control platform, the selection of the whole plant instrument according to the established process parameters, the completion of the design of the corresponding control circuit pipeline and circuit connection drawing, and the joint debugging of the whole factory software parts with the software department. It also includes the design and implementation of a safe environmental oxygen detection system, a fire alarm system, an escape system, an area isolation system, and so on, to ensure the overall establishment and safe implementation of the whole plant system.
