【摘要】：目前,水資源和能源枯竭問題日益突出,全世界都面臨著資源匱乏的問題,尤其是中國。工業(yè)生產(chǎn)是消耗資源的大戶,然而在實(shí)際生產(chǎn)過程中,水與能量的利用效率卻不容樂觀,水在實(shí)際生產(chǎn)中具有重要地位,不僅僅傳遞質(zhì)量,而且往往也是能量的載體,因此,研究實(shí)際生產(chǎn)過程中的水熱同時(shí)優(yōu)化問題具有重大的現(xiàn)實(shí)意義。系統(tǒng)工程是一種很好的解決水熱同時(shí)優(yōu)化問題的方法,本文提出了一種新的概念性方法來解決水熱同時(shí)優(yōu)化問題,該方法不僅可以解決單污染系統(tǒng)的優(yōu)化問題,而且也可以解決多污染的優(yōu)化問題,與此同時(shí)在熱集成方面我們也分別針對(duì)等溫和非等溫?fù)Q熱網(wǎng)絡(luò)進(jìn)行了討論。該方法的創(chuàng)新性主要表現(xiàn)一下幾個(gè)方法:1將溫度參數(shù)考慮到了水網(wǎng)絡(luò)的設(shè)計(jì)中,實(shí)現(xiàn)了用概念法一次性同時(shí)獲得水熱目標(biāo),而不是順序優(yōu)化獲得目標(biāo)值。2首次用概念方法解決了水熱同時(shí)優(yōu)化中的多污染物問題,具有重要的工程應(yīng)用價(jià)值。3提出一種組合曲線圖,來方便進(jìn)行水網(wǎng)絡(luò)的設(shè)計(jì)。本文的主要研究?jī)?nèi)容包括以下幾個(gè)方面:首先,分析了水熱優(yōu)化的基本原理,其優(yōu)化的本質(zhì)其實(shí)就是各個(gè)過程單元根據(jù)濃度和溫度限定條件,選用一種合理的排序方法對(duì)操作單元進(jìn)行排序,使得最終的優(yōu)化網(wǎng)絡(luò)的目標(biāo)值最小。其次,在此理論的基礎(chǔ)上,我們分別提出了兩種不同的設(shè)計(jì)方法來解決單污染和多污染物的水熱同時(shí)優(yōu)化問題。最后,在每種方法下面我們分別采用兩個(gè)到三個(gè)文獻(xiàn)中的例證對(duì)其方法的有效性進(jìn)行驗(yàn)證,通過驗(yàn)證,我們發(fā)現(xiàn)該方法是有效的,而且能夠得出相比其它文獻(xiàn)更為優(yōu)秀的結(jié)果。
[Abstract]:At present, the problem of water resources and energy depletion is becoming increasingly prominent, and the world is facing the problem of resource scarcity, especially in China. Industrial production is a major consumer of resources, but in the actual production process, Water and energy use efficiency is not optimistic, water in practical production has an important position, not only transfer quality, but also often is the carrier of energy, therefore, It is of great practical significance to study the problem of simultaneous optimization of water and heat in practical production. System engineering is a good method to solve the problem of simultaneous optimization of water and heat. In this paper, a new conceptual method is proposed to solve the problem of simultaneous optimization of water and heat. This method can not only solve the optimization problem of single pollution system, but also solve the problem of multi-pollution optimization. At the same time, in the aspect of thermal integration, we also discuss the isothermal non-isothermal heat transfer network separately. The innovation of this method mainly shows that several methods: 1 take the temperature parameter into account in the design of water network. The problem of multiple pollutants in simultaneous hydrothermal optimization is solved by conceptual method for the first time, instead of sequential optimization to obtain target value .2. In this paper, the main research contents include the following aspects: firstly, the basic principle of hydrothermal optimization is analyzed. The essence of optimization is to select a reasonable sorting method to sort the operation units according to the conditions of concentration and temperature, so that the target value of the final optimization network is minimum. Secondly, on the basis of this theory, We propose two different design methods to solve the problem of simultaneous hydrothermal optimization of single and multiple pollutants. Finally, under each method, we use two or three examples in literature to verify the effectiveness of the method. Through verification, we find that the method is effective and can get better results than other literatures.
