【摘要】：往復(fù)壓縮機(jī)屬于化工過(guò)程工業(yè)中最重要的大型設(shè)備之一,在工藝過(guò)程中需要消耗巨大的能量,由于工藝過(guò)程的變化,對(duì)與氣量的要求并不是一成不變的,這就需要對(duì)壓縮機(jī)進(jìn)行調(diào)節(jié),目前在大型壓縮機(jī)上應(yīng)用比較廣泛的調(diào)節(jié)方式主要是旁路調(diào)節(jié),但是回流的氣體是經(jīng)過(guò)壓縮的,壓縮機(jī)的能耗并沒(méi)有降低,國(guó)內(nèi)外學(xué)者普遍比較青睞并著力探究的調(diào)節(jié)方法是部分行程頂開(kāi)進(jìn)氣閥的氣量調(diào)節(jié)方法。 本文主要以?shī)W地利賀爾碧格公司研發(fā)的HydroCOM系統(tǒng)作為研究對(duì)象,從理論上研究推導(dǎo)調(diào)節(jié)工況下壓縮機(jī)的排氣量的計(jì)算,使用CFD軟件對(duì)壓縮機(jī)氣閥內(nèi)氣體的流動(dòng)進(jìn)行模擬分析,探究其壓力場(chǎng)和速度場(chǎng)在閥腔直徑不同的情況下壓力損失的變化以及速度場(chǎng)的分布,通過(guò)實(shí)地參與HydroCOM系統(tǒng)的安裝調(diào)試工作,研究分析其系統(tǒng)構(gòu)成與控制邏輯,通過(guò)調(diào)試分析其節(jié)能與優(yōu)化效果,發(fā)現(xiàn)HydroCOM能夠有效地節(jié)約能源,使壓縮機(jī)運(yùn)行更加平穩(wěn),思考該系統(tǒng)在焦化裝置上使用過(guò)程中出現(xiàn)的問(wèn)題并提出分析推斷。最后進(jìn)行無(wú)級(jí)調(diào)量系統(tǒng)的設(shè)計(jì)嘗試,使用labview虛擬儀器軟件進(jìn)行調(diào)節(jié)系統(tǒng)的設(shè)計(jì)研究,針對(duì)氣閥在卸荷裝置作用下工況的改變以及可能造成的影響進(jìn)行了分析,并作出氣閥設(shè)計(jì)和選材的建議。
[Abstract]:Reciprocating compressor is one of the most important equipment in the chemical process industry. It needs huge energy in the process. This requires the compressor to be adjusted. At present, the most widely used regulation methods on large compressors are bypass regulation, but the reflux gas is compressed, and the compressor energy consumption has not been reduced. Domestic and foreign scholars generally favor and focus on the adjustment method of partial stroke open inlet valve. In this paper, the HydroCOM system developed by Helbig Company of Austria is taken as the research object, and the calculation of compressor exhaust volume under regulating working condition is studied theoretically, and the flow of gas in compressor valve is simulated and analyzed by CFD software. The variation of pressure field and velocity field under the condition of different diameter of valve cavity and the distribution of velocity field are probed into. Through participating in the installation and debugging of HydroCOM system, the system composition and control logic are studied and analyzed. Through debugging and analyzing its energy saving and optimization effect, it is found that HydroCOM can save energy effectively and make the compressor run more smoothly. The problems in the process of using the system in coking plant are considered and the analysis and inference are put forward. Finally, the stepless regulation system is designed and studied by using labview virtual instrument software. The change of the working condition of the valve under the action of unloading device and its possible influence are analyzed. And make the air valve design and material selection recommendations.
