بررسي ميزان توليد گاز زيستي در يك هاضم تركيبي متشكل از مدل هاي چيني و هندي

The amount of biogas produced in a digester combination of Chinese and Indian models

اين مقاله به بررسي، تحليل، طراحي، ساخت و بهره برداري از يك هاضم جديد بيوگاز خانگي براي مصارف روستايي مي‌پردازد. اين هاضم جديد توانايي توليد متوسط بيش از يك مترمكعب بيوگاز را در روز داراست. ميزان بارگيري اوليه 12 تن خوراك و از آن پس روزانه 40كيلوگرم فضولات دامي مي‌باشد. ميزان گاز خروجي در حالت متعارف و بدون تجهيز برابر 1,014 ليتر در روز است كه با به كار بردن همزن 5/6 درصد، سرپوش 21 درصد و همزن و سرپوش 5/27درصد افزايش مييابد. نتايج تجربي بر حسب تعداد روزهاي آزمايش 1 تا 117 روز ارائه شده است

The review, analysis, design, construction and operation of a digester biogas digester is a combination of Indian and Chinese models is investigated. The digester has a low production, which is one of the reasons, there is an outdoor outlet tank of gas that is wasted. Design and construction of digesters in combination to increase production, mechanical agitator to homogenize the feed gas and the caps were used to collect biogas tank outlet. All calculations for the design of the digester, EES V9.430 is done by software. In analyzing the issue, to identify performance improvements, three types of digester 1.simple, 2.equipped with a stirrer and 3.equipped with a stirrer and lid made and tested. Digester volume of 9,600 liters, feed, including cow dung and water that has been mixed with a ratio of one to one. Two cubic meters of gas to cover its output volume and the volume of 350 liters respectively. It has the ability to produce an average of more than one cubic meter biogas digester with reinforced concrete in the country's northwest border (city of Khoy-city Firuraq) is constructed. decreases. Experimental results based on test days 1 to 117 days, for software modeling has been done over the years.
