【摘要】：隨著我國(guó)經(jīng)濟(jì)的快速發(fā)展和農(nóng)民生活水平的顯著提高,農(nóng)民對(duì)室內(nèi)熱環(huán)境的要求也越來越高。以化石能源為燃料進(jìn)行供暖,不僅污染環(huán)境,還加劇了我國(guó)的能源危機(jī),威脅國(guó)家的能源安全。利用生物質(zhì)氣化產(chǎn)生的燃?xì)?能有效改善環(huán)境和緩解能源危機(jī)。并且我國(guó)的生物質(zhì)能源總量非常豐富,分布也極其廣泛,為生物質(zhì)氣化供暖提供了客觀條件。所以基于生物質(zhì)能源的農(nóng)村供暖越來越受到人們的關(guān)注和重視,并被逐步進(jìn)行推廣。本文以天津市小塔沽村為供暖對(duì)象進(jìn)行研究,進(jìn)行了供暖熱負(fù)荷估算,并采用方案比較法,針對(duì)農(nóng)村兩種新能源燃?xì)?生物質(zhì)氣化燃?xì)夂蛻粲谜託?分散供暖的經(jīng)濟(jì)效益(投資、運(yùn)行費(fèi)用、投資回收期)、溫室氣體減排和污染氣體減排進(jìn)行了對(duì)比分析。研究結(jié)果表明戶用沼氣分散供暖初投資要高于生物質(zhì)氣化燃?xì)夥稚⒐┡?前者約為后者的1.86倍;戶用沼氣運(yùn)行費(fèi)用也略微高于生物質(zhì)氣化燃?xì)?而生物質(zhì)氣化燃?xì)夥稚⒐┡暮笃诠芾硪獌?yōu)于戶用沼氣分散供暖。另外,戶用沼氣存在副產(chǎn)物經(jīng)濟(jì)效益,每年可高達(dá)29.9萬元,而生物質(zhì)氣化燃?xì)夥稚⒐┡慕?jīng)濟(jì)效益相對(duì)于戶用沼氣來說較低,可忽略不計(jì)。兩種供暖方式溫室氣體減排和污染氣體減排效益接近。就整體而言,生物質(zhì)氣化燃?xì)夥稚⒐┡慕?jīng)濟(jì)性要優(yōu)于戶用沼氣分散供暖的經(jīng)濟(jì)性。特別針對(duì)農(nóng)村落后的管理水平,生物質(zhì)氣化燃?xì)夥稚⒐┡膬?yōu)點(diǎn)就更加突出。因此類似天津郊區(qū)這樣的農(nóng)村地區(qū),供暖期需要大量燃?xì)獾霓r(nóng)村建議采用生物質(zhì)氣化燃?xì)夥稚⒐┡绞�。同時(shí)以小塔沽村為對(duì)象,采用技術(shù)經(jīng)濟(jì)分析方法,對(duì)生物質(zhì)氣化集中供暖和分戶供暖兩種方案進(jìn)行對(duì)比分析,考察供暖設(shè)備、折舊年限、運(yùn)行費(fèi)用等因素對(duì)經(jīng)濟(jì)效益及投資回收期的影響,給出了天津市小塔沽村的供暖優(yōu)化方案。論文最后介紹農(nóng)村居民對(duì)生物質(zhì)氣化分戶供暖所采取的節(jié)能措施,通過實(shí)驗(yàn)研究,比較影響節(jié)能的主要因素。通過e-QUEST軟件對(duì)該用戶的熱負(fù)荷及把門窗減小為原來一半時(shí)的熱負(fù)荷(由于門窗較大,減小為原來的一半,不影響通風(fēng)及人員通行)進(jìn)行模擬,進(jìn)一步驗(yàn)證了實(shí)驗(yàn)結(jié)論,即對(duì)于類似農(nóng)村保溫效果不好的房屋,提高其維護(hù)結(jié)構(gòu)的保溫效果,將能更有效地實(shí)現(xiàn)節(jié)能。本文從經(jīng)濟(jì)適用性、環(huán)境效益角度為類似農(nóng)村地區(qū)燃料、供暖方式選擇提供參考。通過實(shí)驗(yàn)和模擬所得結(jié)論能為農(nóng)村生物質(zhì)氣化分戶供暖節(jié)能措施提供科學(xué)的技術(shù)參考,澄清以往人們對(duì)農(nóng)村分戶供暖節(jié)能措施的一些誤解。
[Abstract]:With the rapid development of Chinese economy and the remarkable improvement of farmers' living standard, farmers' demands on indoor thermal environment are higher and higher.Using fossil energy as fuel for heating not only pollutes the environment, but also intensifies the energy crisis and threatens the national energy security.The gas produced by biomass gasification can effectively improve the environment and alleviate the energy crisis.The biomass energy in China is very abundant and widely distributed, which provides objective conditions for biomass gasification heating.Therefore, people pay more and more attention to the rural heating based on biomass energy, and it is gradually popularized.In this paper, taking Xiaotagu village in Tianjin as the heating object, the heating load is estimated, and the scheme comparison method is adopted.The economic benefits (investment, operating cost, investment recovery period, greenhouse gas emission reduction and pollution gas emission reduction) of two new energy gas (biomass gasification gas and household biogas) heating in rural areas were compared and analyzed.The results show that the initial investment of household biogas dispersion heating is 1.86 times higher than that of biomass gasification gas dispersion heating, and the household biogas operation cost is slightly higher than biomass gasification gas.The later management of biomass gasification gas dispersion heating is better than that of household biogas dispersion heating.In addition, the economic benefit of household biogas is as high as 299000 yuan per year, but the economic benefit of biomass gasification gas dispersion heating is lower than that of household biogas, which can be ignored.The greenhouse gas emission reduction and the pollution gas emission reduction benefit are close to each other.On the whole, the economy of biomass gasification gas dispersive heating is better than that of household biogas dispersion heating.Especially for the backward management level in rural areas, the advantages of biomass gasification gas dispersion heating are more prominent.Therefore, in rural areas such as the suburbs of Tianjin, biomass gasification gas dispersion heating is recommended for the rural areas where a large amount of gas is needed in heating period.At the same time, taking Xiaotagu village as the object, adopting the method of technical and economic analysis, this paper makes a comparative analysis of the two schemes of biomass gasification central heating and household heating, and inspects the heating equipment and the depreciation years.The optimization scheme of heating in Tianjin Xiaotagu Village is given in this paper because of the influence of operation cost on economic benefit and the payback period of investment.Finally, the paper introduces the energy saving measures taken by rural residents in biomass gasification household heating, and compares the main factors affecting energy saving through experimental research.The thermal load of the user and the heat load when the windows and doors are reduced to half of the original are simulated by e-QUEST software. The experimental results are further verified by the simulation of the heat load of the user, which is reduced to the original half because of the large windows and doors, and does not affect the ventilation and the passage of people.That is to say, for houses similar to the poor thermal insulation in rural areas, it will be more effective to save energy by improving the insulation effect of the maintenance structure.This paper provides a reference for the choice of fuel and heating mode in rural areas from the point of view of economic applicability and environmental benefit.The results of experiments and simulations can provide a scientific and technical reference for energy saving measures in rural biomass gasification household heating, and clarify some misunderstandings about energy saving measures for household heating in rural areas in the past.
