操作沼氣脫硫設(shè)備前應(yīng)了解哪些知識(shí)?

沼氣作為可再回用清潔能源,在污染問題日益顯現(xiàn)的情況下逐漸被社會(huì)重視。因沼氣中會(huì)含有硫化氫,燃燒之后易生成二氧化硫等有害物質(zhì),因此在使用沼氣之前須將其中的硫化氬除去。

As a renewable and clean energy, biogas has been paid more and more attention by the society under the condition of increasing pollution problems. Because the biogas contains hydrogen sulfide, it is easy to generate harmful substances such as sulfur dioxide after combustion, so the argon sulfide must be removed before using the biogas.
因?yàn)榱蚧瘹寰哂休^強(qiáng)的損害性,對(duì)人們身體能造成損害,因此應(yīng)實(shí)現(xiàn)脫硫系統(tǒng)自動(dòng)化,減少人工操作步驟。沼氣脫硫設(shè)備自動(dòng)控制系統(tǒng),具有實(shí)現(xiàn)脫硫自動(dòng)控制、運(yùn)行狀態(tài)顯示、風(fēng)機(jī)變頻調(diào)速、故障監(jiān)控報(bào)警等作用,在增加自動(dòng)化水平的前提下,保障脫硫效率,保障脫硫系統(tǒng)能夠安全穩(wěn)定的運(yùn)行,在應(yīng)用前我們應(yīng)對(duì)該設(shè)備作哪些了解呢?接下來我們來探討一下:
Because argon sulfide has strong damage and can cause damage to people's body, the automation of desulfurization system should be realized and manual operation steps should be reduced. The automatic control system of biogas desulfurization equipment can realize automatic desulfurization control, operation status display, fan frequency conversion speed regulation, fault monitoring and alarm. On the premise of increasing the automation level, it can ensure the desulfurization efficiency and ensure the safe and stable operation of the desulfurization system. What should we know about the equipment before application? Next, let's discuss:
 
其一,應(yīng)先了解了沼氣脫硫的意義,根據(jù)沼氣脫硫工藝流程,分析工藝操作過程,給出脫硫控制系統(tǒng)的設(shè)計(jì)方案。了解沼氣脫硫設(shè)備的控制系統(tǒng),包括觸摸屏、模擬量輸入輸出模塊、變頻器等。
First, we should first understand the significance of biogas desulfurization, analyze the process operation process according to the biogas desulfurization process, and give the design scheme of desulfurization control system. Understand the control system of biogas desulfurization equipment, including touch screen, analog input and output module, frequency converter, etc.
其次,對(duì)脫硫控制系統(tǒng)進(jìn)行了軟件設(shè)計(jì),究成了S7-200PLC的控制系統(tǒng)梯形圖設(shè)計(jì)受組分濃度大小不同的影響,風(fēng)機(jī)開度也需隨之進(jìn)行調(diào)整,從而保障輸送的空氣能夠充分反應(yīng)掉,增加脫硫液的再回用效率。系統(tǒng)依據(jù)實(shí)時(shí)檢測到的組分濃度,利用PID控制器計(jì)算出相應(yīng)的空氣進(jìn)量,并通過變頻器對(duì)風(fēng)機(jī)進(jìn)行調(diào)整。在設(shè)計(jì)脫硫液補(bǔ)液、排液以及循環(huán)泵啟停的時(shí)候,不同的操作須對(duì)應(yīng)不同的啟停時(shí)間。
Secondly, the software of the desulfurization control system is designed, and the control system ladder diagram of S7-200 PLC is studied. Due to the influence of different component concentrations, the fan opening also needs to be adjusted, so as to ensure that the transmitted air can fully react and increase the reuse efficiency of desulfurization liquid. According to the component concentration detected in real time, the system uses PID controller to calculate the corresponding air inlet, and adjusts the fan through frequency converter. During the design of desulfurizing liquid replenishment, liquid discharge and the start and stop of circulating pump, different operations must correspond to different start and stop times.
然后,設(shè)計(jì)觸摸屏監(jiān)控界面,利用MCGS組態(tài)軟件完成脫硫控制系統(tǒng)監(jiān)控界面設(shè)計(jì),在組態(tài)環(huán)境下,建立新工程,構(gòu)造實(shí)時(shí)數(shù)據(jù)庫、主控窗口和設(shè)備窗口等,實(shí)現(xiàn)對(duì)系統(tǒng)運(yùn)行的實(shí)時(shí)在線監(jiān)控,對(duì)出現(xiàn)的狀況進(jìn)行及時(shí)響警聲。
Then, the touch screen monitoring interface is designed, and the MCGS configuration software is used to complete the monitoring interface design of the desulfurization control system. Under the configuration environment, a new project is established, and the real-time database, main control window and equipment window are constructed to realize the real-time online monitoring of the system operation and give a timely alarm to the existing conditions.
末后,在現(xiàn)場對(duì)沼氣脫硫設(shè)備系統(tǒng)硬件進(jìn)行組裝,著重檢查可能出現(xiàn)的問題,對(duì)控制系統(tǒng)進(jìn)行調(diào)試。
Finally, assemble the system hardware of biogas desulfurization equipment on site, focus on the possible problems, and debug the control system.
