本文通过中石化大牛地气田第二甲醇污水处理站倒班点太阳能热水系统的应用实例,分析了太阳能热水系统在该类地区应用的实用性、经济性和优势,并针对该类地区的区域特点对于系统设计应着重考虑的问题及应对措施进行了详细的说明。该倒班点位于内蒙古地区乌审旗境内,运行结果证明太阳能热水系统完全能够在处理寒冷地区的油气田倒班点推广应用,节能效果明显。 This paper analyzes the practicality, economy and advantage of solar hot water system applied in this kind of area through the application example of the solar hot water system of the second methanol wastewater treatment station in Sinopec Daniudi Gas Field. In addition, Features For system design should focus on the consideration of problems and countermeasures were described in detail. The shift point is located in Wushen County, Inner Mongolia. The operation results show that the solar water heating system can fully popularize the application of oil and gas fields in cold areas and energy saving effect is obvious.
