【摘要】：隨著國家經(jīng)濟的建設(shè)和公路事業(yè)的發(fā)展，公路修建的標(biāo)準(zhǔn)不斷提高，這就需要我們提高瀝青路面的攤鋪質(zhì)量。攤鋪機熨平板的預(yù)加熱與否，將嚴(yán)重影響到攤鋪機起步時的攤鋪質(zhì)量。因此為了提高攤鋪機的工作效率和攤鋪質(zhì)量，就需要對熨平板進行高效快速的加熱。 本文以攤鋪機熨平板的加熱系統(tǒng)為研究對象，介紹了現(xiàn)有攤鋪機熨平板加熱的方法，分析其具有的優(yōu)缺點，提出了使用柴油為燃料的新型加熱方法。為了提高柴油的燃燒質(zhì)量，就必須使柴油發(fā)生霧化，霧化效果的好壞將直接影響柴油的燃燒質(zhì)量。介紹了液體霧化的三種主要霧化方式，通過研究燃油的霧化過程，建立射流霧化模型，分析影響霧化的因素，尋找提高霧化的質(zhì)量的方法。研究了單滴油滴蒸發(fā)燃燒的模型和分析了柴油燃燒的過程，計算出柴油完全燃燒時所需的空氣量，產(chǎn)生煙氣的量，分析了攤鋪機熨平板加熱燃燒室內(nèi)燃燒傳熱的過程。對攤鋪機熨平板加熱系統(tǒng)提出可行性方案，分析各種方案的特點，對比它們的優(yōu)缺點，，綜合分析并選擇最優(yōu)方案。通過與使用液化天然氣加熱方法的經(jīng)濟性對比，得出使用柴油為燃料加熱熨平板是一種高效快速并且經(jīng)濟的加熱方法。
[Abstract]:With the development of national economy and highway construction, the standard of highway construction has been improved, which requires us to improve the paving quality of asphalt pavement. The pre-heating of paver ironing plate will seriously affect the paving quality when paver starts. Therefore, in order to improve the working efficiency and spreading quality of paver, it is necessary to heat the ironing plate efficiently and quickly. This paper takes the heating system of paver ironing plate as the research object, introduces the existing paver ironing plate heating method, analyzes its advantages and disadvantages, and puts forward a new heating method using diesel oil as fuel. In order to improve the combustion quality of diesel oil, it is necessary to atomize diesel oil, and the effect of atomization will directly affect the combustion quality of diesel oil. Three main atomization methods of liquid atomization are introduced. By studying the atomization process of fuel, the jet atomization model is established, the factors influencing the atomization are analyzed, and the methods to improve the atomization quality are found. The model of single droplet evaporative combustion and the combustion process of diesel oil are studied. The air volume and the amount of flue gas produced when diesel oil is completely burned are calculated and the process of combustion heat transfer in the combustion chamber heated by ironing plate of paver is analyzed. This paper presents a feasible scheme for paver ironing plate heating system, analyzes the characteristics of various schemes, compares their advantages and disadvantages, and synthetically analyzes and selects the optimal scheme. Compared with the heating method of liquefied natural gas (LNG), it is concluded that using diesel as fuel to heat ironing plate is an efficient, fast and economical heating method.
