【摘要】：本論文主要對包頭市地區(qū)工業(yè)廠房在采暖過程中的采暖末端設(shè)備和采暖熱源進(jìn)行了優(yōu)化研究，包頭市地處中國北方地區(qū)，屬于寒冷地區(qū)，所以工業(yè)廠房的采暖問題受到了高度的重視。工業(yè)廠房的采暖形式及在采暖過程中出現(xiàn)主要問題有以下幾個：采暖空間達(dá)不到理想的效果、水平方向和垂直方向的溫度梯度非常大，在設(shè)計過程中，按照計算的負(fù)荷和室內(nèi)設(shè)計要求的溫度布置了足夠的散熱器，但是總是達(dá)不到理想的采暖效果往往不能明確原因。針對這些問題作者通過現(xiàn)場調(diào)研、CFD模擬分析和經(jīng)濟(jì)性分析計算對包頭市某機(jī)械成品加工車間的采暖工程進(jìn)行了優(yōu)化設(shè)計，提出適合工業(yè)廠房的采暖系統(tǒng)。 首先通過對包頭市20家中小型機(jī)械加工廠的現(xiàn)場調(diào)研，了解了一下工業(yè)廠房在采暖過程中所使用的采暖末端設(shè)備、采暖熱源和生產(chǎn)過程中的余熱廢熱情況，經(jīng)過對調(diào)研數(shù)據(jù)的整理分析確定研究方案。 然后運(yùn)用CFD模擬軟件對各個方案進(jìn)行了數(shù)值模擬，對模型從室內(nèi)空氣的溫度場、空氣的速度場等方面對室內(nèi)環(huán)境的熱舒適性進(jìn)行了比較。通過對比傳統(tǒng)散熱器和暖風(fēng)機(jī)在采暖時的室內(nèi)溫度和速度場，得到采用暖風(fēng)機(jī)平行送風(fēng)，，風(fēng)速保持在5m/s，出風(fēng)口角度為水平傾角45°，安裝高度為5m時的采暖效果最好，水平方向和豎直方向上的溫度分布都很均勻。 最后從熱源方面采用經(jīng)濟(jì)性計算分析的方法對工業(yè)廠房的采暖熱源形式做了經(jīng)濟(jì)性評價。通過經(jīng)濟(jì)性的計算結(jié)果分析得到，初投資最高的費(fèi)用是太陽能采暖系統(tǒng)，最低的是污水源熱泵系統(tǒng)；年運(yùn)行費(fèi)用最高的是燃油熱水鍋爐，最低的是污水源熱泵系統(tǒng)；費(fèi)用年值最高的是燃油鍋爐，最低的是污水源熱泵，其次是太陽能采暖系統(tǒng)。 本論文對今后的工業(yè)廠房采暖設(shè)計具有很重要的指導(dǎo)意義，在解決廠房采暖問題作為很好的依據(jù)。
[Abstract]:This paper mainly studies the optimization of heating terminal equipment and heating heat source of industrial plant in Baotou area. Baotou city is located in the north of China and belongs to the cold region. Therefore, the heating problem of industrial factory buildings is highly valued. The heating forms of industrial buildings and the main problems in the process of heating are as follows: the heating space can not achieve the desired results. The temperature gradient in horizontal and vertical direction is very large, in the design process, according to the calculated load and the temperature required by the indoor design, enough radiators are arranged. But always can not reach the ideal heating effect is often not clear reasons. In view of these problems the author through field research. The optimization design of heating engineering in a mechanical finished product processing workshop in Baotou City was carried out by CFD simulation analysis and economic analysis calculation, and the heating system suitable for industrial workshop was put forward. First of all, through the field investigation of 20 small and medium-sized machinery processing plants in Baotou City, we know the end heating equipment, heating heat source and waste heat in the process of production. Through the research data collation and analysis to determine the research program. Then the CFD simulation software is used to simulate the temperature field of the model from the indoor air. The thermal comfort of indoor environment is compared in terms of air velocity field and so on. By comparing the indoor temperature and velocity field of traditional radiator and heating fan, the parallel air supply with heating fan is obtained. When the wind speed is kept at 5 m / s, the outlet angle is 45 擄horizontal dip angle, and the installation height is 5 m, the heating effect is the best, and the temperature distribution in horizontal and vertical direction is very uniform. Finally, the economic evaluation of the heating source form of industrial plant is made by using the method of economic calculation and analysis from the aspect of heat source, and the result of economic calculation is obtained. The highest initial investment is solar heating system, the lowest is sewage source heat pump system; The annual running cost is the highest for oil-fired hot water boiler and the lowest for sewage source heat pump system. The highest annual cost is oil-fired boiler, the lowest is sewage source heat pump, followed by solar heating system. This paper has very important guiding significance for the future industrial workshop heating design, as a good basis to solve the factory building heating problem.
